[0004]

The parabolic antenna for broadcasting satellite reception and line-of-sight communication described above has a very narrow directivity, and the antenna support angle and direction are major factors that affect the characteristics of the antenna. . However, in the antenna supporting device in the conventional example, in the case of FIG. 7 and FIG. 8, when the wind pressure due to the wind is received from, for example, the direction of W3, this structure is received by the entire pole 17, so that a relatively rotational moment is not generated. , W1 and W2, when a wind pressure is applied, a rotational moment is generated in the direction M, and the U-shaped bolt 16 and the pole 17 are loosened for a long time and the direction of the main reflecting mirror 14 is changed. The problem occurs. In addition, FIG.
In the case of, since the distance between the pole 4 and the reflecting mirror 1 is long, a larger rotation moment is generated. That is, the rotational moment M2 is generated with respect to the wind pressure W1, and the rotational moment M1 is generated with respect to the wind pressure W2. Particularly, when the wind pressure is W1, the largest rotational moment is generated, which causes a problem that the direction of the reflecting mirror 1 is changed. In view of the above problems, the present invention particularly provides a support device that supports an antenna with a support member having a certain length, and an antenna support that prevents rotation of the antenna by a structure that cancels a rotation moment due to wind pressure received by the antenna. The purpose is to provide a device.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides an antenna supporting device for supporting an antenna on a support by a supporting member, wherein the antenna and a balance means for receiving wind pressure. A support member for fixing the antenna and the balance means, and a fixing means for fixing the support member to the column, the balance means being provided in a direction substantially orthogonal to a radio wave arrival direction of the antenna. In addition, the antennas are arranged at positions substantially symmetrical with respect to the supporting column so as to receive a wind pressure load substantially equal to a wind pressure load from the direction of arrival of the radio wave of the antenna.
Wind pressure weighting is the weighting force determined by the shape and area. Small parabolic antennas are usually not equipped with a radome to prevent snow damage. Therefore, the arrival direction of the radio wave is curved, and the shape is such that wind pressure is easily applied by the wind. Therefore, when the wind is strong, a considerable amount of wind pressure is applied to the support member, and a rotation moment is generated with the support as a fulcrum. This causes the antenna to rotate and deteriorate the directivity of the radio wave. In order to prevent this, there is a method of increasing the frictional resistance by thickening the support pillar or strengthening the fixation with the support pillar, or making the shape of the support pillar into a prismatic shape to obtain a fixing force that overcomes the rotational moment. However, these methods are disadvantageous in that they are costly and that the orientation of the antenna cannot be adjusted freely. Therefore, a wind pressure load equal to the wind pressure load applied to the antenna is created, and a rotation moment is generated in a direction to cancel the rotation moment. According to the invention, the balance means is provided in a direction substantially orthogonal to the radio wave arrival direction of the antenna, and the balancer is centered on the column so as to receive the wind pressure load substantially equal to the wind pressure load from the radio wave arrival direction of the antenna. Since the antennas are arranged at symmetrical positions, the rotational moment can be canceled to prevent the antenna from rotating and the directional characteristics can be stabilized.

The invention according to claim 2 is an antenna supporting device for supporting an antenna on a support by a supporting member,
The antenna, a balance means for receiving a wind pressure, a support member for fixing the antenna and the balance means, and a fixing means for fixing the support member to the support column, wherein the balance means is a radio wave arrival direction of the antenna. Is provided in a direction substantially orthogonal to and a direction substantially parallel to, and the pillar is centered so as to receive wind pressure load from the direction of arrival of radio waves of the antenna or wind pressure load from the side direction of the antenna. It is characterized in that they are arranged at positions substantially symmetrical to each other. It is not possible to confirm in advance which direction the wind will come from with respect to the antenna. The wind with the highest wind pressure is from the front and back of the antenna, and the second is the wind with the side of the antenna. Therefore, in order to cancel it, it is preferable to make the balance means L-shaped so as to receive the wind from the side surface. According to such a technical means, the balance means is provided in a direction parallel to a direction substantially orthogonal to the radio wave arrival direction of the antenna, and the wind pressure is applied from the antenna radio wave arrival direction or the wind pressure is applied from the side surface direction of the antenna. Since it is arranged in a symmetrical position about the pillar so as to receive a wind pressure load substantially equal to the load,
Wind pressure load from the side of the antenna can be offset.
According to a third aspect of the present invention, the balance means has an L-shape, and the balance means is oriented substantially orthogonal to the radio wave arrival direction of the antenna and the balance means is substantially orthogonal to the radio wave arrival direction of the antenna. It is also an effective means of the present invention that the balance means oriented in the parallel direction is configured to receive different wind pressure loads. Wind pressure load from the side of the antenna
Since the area exposed to the wind and the surface shape are convexly curved, the wind pressure load is overwhelmingly smaller than the front surface. Therefore, the shape is determined such that the wind pressure load of the balancing means is also reduced in proportion thereto. According to such technical means, the wind pressure load in the direction substantially orthogonal to the arrival direction of the radio wave of the antenna,
Since the wind pressure weights are formed in different shapes parallel to the direction of arrival of radio waves from the antenna, the wind pressure weights are well balanced, and the rotational moment can be further reduced.

The invention according to claim 4 is also an effective means of the present invention in that the wind pressure load of the balance means in a direction substantially orthogonal to the radio wave arrival direction of the antenna can be adjusted. The wind pressure applied to the antenna changes variously depending on the shape and area of the antenna. It is possible to measure the wind pressure load in advance and prepare a balance means having the same wind pressure load, but if the antenna is replaced after that, the balance means must be changed. Therefore, if the wind pressure load of the balancing means can be adjusted, it is possible to cope with the change of the antenna. According to such a technical means, since the wind pressure load of the balance means can be adjusted, it is possible to set an appropriate wind pressure load, and it is possible to flexibly deal with the change of the antenna. Further, the invention of claim 5 is an effective means of the present invention, wherein the balance means is integrally formed in a direction substantially orthogonal to a direction of arrival of radio waves of the antenna and in a direction substantially parallel to the direction. Originally, the balance means is not always necessary due to the characteristics of the antenna. Therefore, it is preferable to realize it by a method with the lowest possible cost. According to this technical means, the balance means is integrally configured in a direction substantially parallel to the direction of arrival of radio waves from the antenna and in a direction parallel to the direction of arrival of the radio waves. . Further, the invention of claim 6 is an effective means of the present invention, wherein the balance means is formed separately in a direction substantially orthogonal to a direction of arrival of radio waves from the antenna and a direction substantially parallel to the direction. . The wind pressure load from the side of the antenna may be almost negligible depending on the shape of the antenna. In this case, the balancing means for the side surface is not required, so this selection is possible if the front surface and the side surface are separately configured. According to such a technical means, the balance means is separately configured in a direction substantially parallel to the direction of arrival of radio waves from the antenna and in a direction parallel to the direction, so that unnecessary balance means can be eliminated, resulting in cost reduction. Becomes

According to a seventh aspect of the present invention, there is provided an antenna supporting device for supporting an antenna on a support by a supporting member,
The antenna, a balance means for receiving wind pressure, a support member for fixing the antenna and the balance means, and a fixing means for fixing the support member to the column, the balance means in the same shape as the antenna. Is formed and is provided in a direction substantially orthogonal to the radio wave arrival direction of the antenna, and is substantially symmetrical about the pillar so that the wind pressure load from the antenna radio wave arrival direction and the wind pressure load from the side surface are received substantially equally. Is further retracted by the thickness of the antenna at the position. The wind pressure applied to the antenna is the second largest after the wind pressure applied from the back.
However, the shape of the back surface of the antenna is convexly curved, and the projected area is the same as that of the front surface, but the wind pressure load is significantly different. For this reason, in the case of the flat plate balancer, the wind pressure applied to the balancer by the wind from the back surface may be increased and the balance may be lost. Therefore, if you use a balancer that has exactly the same shape as the antenna, you can solve such a problem.In addition, in order to cancel the wind pressure load from the side, the balancer is deliberately retracted by the thickness of the antenna. It is arranged so that the balance means receives wind pressure from the side under the same conditions as the antenna. According to such a technical means, since the wind pressure load from the direction of arrival of the radio wave of the antenna and the wind pressure load from the side surface are received substantially equally, the antenna is further arranged at a symmetrical position with respect to the support column by the thickness of the antenna. , It is possible to cancel the wind pressure load from all directions. Further, the invention of claim 8 is an effective means of the present invention, wherein the balance means is made of a dielectric material having a high radio wave transmittance. The main reflector of the antenna has the role of reflecting radio waves and focusing the radio waves on the feedphone. Therefore, it is preferable that there is nothing around the antenna that causes unnecessary reflection. Therefore, it is preferable that the material of the balancer is also a material that reflects radio waves. According to such a technical means, since the balance means is made of a dielectric material having a high radio wave transmittance, unnecessary reflection can be suppressed, a rotation moment due to wind pressure load can be prevented, and the balance means can be lightened.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to the embodiments shown in the drawings. However, the constituent elements, types, combinations, shapes, relative arrangements, and the like described in this embodiment are merely explanatory examples, not the gist of limiting the scope of the present invention thereto, unless specifically stated. .. FIG. 1 is a configuration diagram of an antenna support device according to a first embodiment of the present invention. (A) is the top view, (b)
[Fig. 3] is a rear view seen from the view A of (a). This configuration has a main reflection mirror 20 that reflects and focuses radio waves, a feedphone 21 that receives fixed and focused radio waves and that emits radio waves, and an antenna fixing that fixes the main reflection mirror 20 to a support member 23. A member 22, a balance plate 26 that receives wind and generates wind pressure, a support member 23 that fixes the antenna fixing member 22 and the balance plate 26, and a U-shaped bolt 24 that supports and fixes the support member 23 to a support column 28. The balance plate 26 is fixed by bolts 27 in a direction orthogonal to the radio wave arrival direction of the main reflecting mirror 20. In the figure, the U-shaped bolt 24 is fixed to the support column 28 by two nuts 25, but the number may be any number. Further, a fixing method other than the U-shaped bolt may be used.

Next, a description will be given of the case where the wind hits the antenna supporting device having this structure in the directions W1 and W2. When W is a wind pressure load, the rotational moment generated by the support member 23 with the support 28 as a fulcrum by the wind pressure load W1 generated by the main reflecting mirror 20 is M1. If the support member 23 and the support column 28 are fixed by a frictional force that overcomes the rotational moment M1, the support member 23 does not rotate. However, if this rotational moment M1 is constantly applied for a long period of time, the frictional force gradually decreases, and there is a risk that the rotational moment M1 cannot be resisted and the motor rotates. Therefore, in the present embodiment, the main reflecting mirror 20 is placed at a position symmetrical with the main reflecting mirror 20 about the support column 28.
The balance plate 26 having the same wind pressure load as the above is arranged. As a result, due to the wind pressure load W2 generated on the balance plate 26, a rotation moment M2 is generated which is generated by the support member 23 with the support 28 as a fulcrum. Here, since the main reflecting mirror 20 and the balance plate 26 are close to each other, the wind pressure loads W1 and W2 are equal, and as a result, the rotational moments M1 and M2 are also equal. Moreover, since the directions of M1 and M2 are opposite to each other, they cancel each other out, and as a result, rotation does not occur. As described above, the wind pressure weighting is the weighting force determined by the shape and the area.
Small parabolic antennas are usually not equipped with a radome to prevent snow damage. Therefore, the arrival direction of the radio wave is curved, and the shape is such that wind pressure is easily applied by the wind. Therefore, a considerable amount of wind pressure is applied to the support member 23 in a strong wind, and a rotation moment is generated with the support column 28 as a fulcrum. This causes the antenna to rotate and deteriorate the directivity of the radio wave. In order to prevent this, there is a method of increasing the frictional resistance by thickening the support pillar or strengthening the fixation with the support pillar, or making the shape of the support pillar into a prismatic shape to obtain a fixing force that overcomes the rotation moment. However, these methods are disadvantageous in that they are costly and that the orientation of the antenna cannot be adjusted freely. Therefore,
Create a wind pressure load equal to the wind pressure load on the antenna,
Generate a rotation moment in a direction that cancels the rotation moment. As a result, the balance plate 26 is provided in a direction substantially orthogonal to the radio wave arrival direction of the antenna, and is placed symmetrically with respect to the support column 28 so as to receive the wind pressure load substantially equal to the wind pressure load from the antenna radio wave arrival direction. Since the antenna is arranged, the rotation moment is canceled to prevent the antenna from rotating and the directional characteristics can be stabilized.

FIG. 2 is a block diagram of an antenna support device according to a second embodiment of the present invention. (A) is the top view, (b) is the rear view seen from the C view of (a). Since the same components are designated by the same reference numerals, duplicate description will be omitted. 2 is different from FIG. 1 in that the shape of the balance plate is different and the balance plate is L-shaped to cancel the wind pressure load from the side surface. The structure of this balance plate is such that the stay 30 is attached to the support member 23, and the balance plate 31 is retracted from the main reflecting mirror 20 so as to accurately apply wind pressure load from the side surface.

Next, a description will be given of a case where the wind hits the antenna supporting device having this structure in the directions W1, W2, W3 and W4. If W is the wind pressure load, the main reflecting mirror 20
The support member 23 is supported by the support 28 by the wind pressure load W1 generated in
The rotational moment generated with the fulcrum as the fulcrum is M1. If the support member 23 and the support column 28 are fixed by a frictional force that overcomes the rotational moment M1, the support member 23 does not rotate. However, if this rotational moment M1 is constantly applied for a long period of time, the frictional force gradually decreases, and there is a risk that the rotational moment M1 cannot be resisted and the motor rotates. Therefore, in the present embodiment, at a position symmetrical with the main reflecting mirror 20 about the pillar 28,
A balance plate 31 having a B surface having the same wind pressure load as that of the main reflecting mirror 20 is arranged. Thereby, B of the balance plate 31
The supporting member 23 is supported by the support 2 by the wind pressure load W2 generated on the surface.
A rotation moment M2 is generated which is generated with 8 as a fulcrum. Here, since the main reflecting mirror 20 and the balance plate 31 are close to each other, the wind pressure loads W1 and W2 are equal, and as a result, the rotational moments M1 and M2 are also equal. Moreover, M1 and M
Since 2 is in the opposite direction, they cancel each other out, and as a result, rotation does not occur. The balance plate 31 also has an A surface having the same wind pressure load W4 as the side surface of the main reflecting mirror 20. Thereby, the wind pressure load W4 generated on the A surface of the balance plate 31
As a result, a rotation moment M2 generated by the support member 23 with the support column 28 as a fulcrum is generated. Here, since the main reflecting mirror 20 and the balance plate 31 are close to each other, wind pressure loads W3 and W4 are applied.
Are equal and, as a result, the rotational moments M1 and M2 are also equal. Thus, it is not possible to confirm in advance which direction the wind will come from with respect to the antenna. The wind with the highest wind pressure is from the front and back of the antenna, and the second is the wind with the side of the antenna. Therefore, if the balance plate 31 is L-shaped so as to cancel it, and the wind from the side surface is also received, the wind pressure load from the side surface of the antenna can be canceled.

FIG. 3 is a configuration diagram of an antenna support device according to a third embodiment of the present invention. (A) is the top view, (b) is the rear view seen from the C view of (a). Since the same components are designated by the same reference numerals, duplicate description will be omitted. 3 is different from FIG. 2 in that the shape of the balance plate is different, and the stay is omitted and one plate is L-shaped and directly attached to the support member 23. The configuration of this balance plate is such that the balance plate 33 is directly attached to the support member 23 by the bolts 32, and the A surface of the balance plate 33 is projected rearward from the main reflecting mirror 20 so that the wind pressure from the side surface is accurately received. I have to. The operation of this structure is the same as in the case of FIG. As a result, the material cost of the balance plate 33 is low, and further, the processing is easy and the cost can be reduced.

FIG. 4 is a configuration diagram of an antenna support device according to a fourth embodiment of the present invention. (A) is the top view, (b) is the rear view seen from the C view of (a). Since the same components are designated by the same reference numerals, duplicate description will be omitted. 4 is different from FIG. 3 in that
The point is that the surface B and the surface B are separate bodies, and the surface B can be expanded and contracted. In this configuration, the support member 23 receives a wind pressure load on the side of the T-shape on the support member 23, the balance plates 34 and 35 receive wind pressure load from the direction of arrival of the radio wave, and the support member 2 for supporting them.
The balance plate 34 is formed of four bolts 37, and two long holes 38 are formed in the balance plate 34.
It is slidably supported by a stay 39 provided in the No. 5. The wind pressure applied to the antenna changes variously depending on the shape and area of the antenna. It is possible to measure the wind pressure load in advance and prepare a balance plate having the same wind pressure load, but if the antenna is replaced after that, the balance plate must also be changed. Therefore, if the balance plate is slid up and down to adjust the wind pressure load as described above, it is possible to cope with the change of the antenna. As a result, it is possible to set an appropriate wind pressure load and flexibly respond to antenna changes.

FIG. 5 is a configuration diagram of an antenna support device according to a fifth embodiment of the present invention. (A) is the top view, (b) is the rear view seen from the A view of (a). Since the same components are designated by the same reference numerals, duplicate description will be omitted. 5 is different from FIGS. 1 to 4 in that the support member is of a crank type and the balancing means is not the plate shape but the same shape as the antenna. This is because not only the wind pressure applied from the front surface but also the wind moment applied from the side surface and the back surface accurately cancels the rotational moment. This configuration is composed of a crank type support member 53, a curved type balance means 50 arranged at a position symmetrical to the main reflecting mirror 20, and a balance means fixing member 51 fixed to the support member 53. . As described above, the wind pressure applied to the antenna is the second largest next to the wind applied to the wind pressures W4 and W5 from the back. However, the shape of the back surface of the antenna is convexly curved, and the projected area is the same as the front surface, but the wind pressure load is smaller than that of the front surface. For this reason, in the case of the flat balance plate, the wind pressure applied to the balance plate against the wind from the back becomes large and the balance may be lost. Therefore, such a problem can be solved by using the balance means 50 having the same shape as the shape of the antenna. Further, in order to cancel the wind pressure load from the side surface, the shape of the support member 53 is made into a crank shape, and the balance means is formed. 50 is intentionally arranged at a position retracted by the thickness of the antenna, and the balance means 50 is also subjected to wind pressure load from the side surface under the same conditions as the antenna. As a result, the wind pressure load from all directions can be offset.
As described above, the main reflecting mirror 20 of the antenna serves to reflect the radio waves and focus the radio waves on the feedphone 21. Therefore, it is preferable that there is nothing around the antenna that causes unnecessary reflection. Therefore, it is preferable that the balance plate and the balance means are made of a material that reflects radio waves. To that end, if the material is made of a dielectric material having a high radio wave transmittance, unnecessary reflection is not caused, a rotational moment due to wind pressure is prevented, and it is possible to realize a light weight.

[0016]

As described above, according to the present invention, the balance means is provided in a direction substantially orthogonal to the radio wave arrival direction of the antenna, and the wind pressure is applied from the radio wave arrival direction of the antenna. Since the struts are arranged symmetrically with respect to the support so as to receive a wind pressure load substantially equal to, the rotation moment can be canceled to prevent the antenna from rotating and the directional characteristics can be stabilized. According to a second aspect of the present invention, the balance means is provided in a direction parallel to a direction substantially orthogonal to a radio wave arrival direction of the antenna, and a wind pressure load from a direction of arrival of the radio wave of the antenna or a wind pressure load from a side direction of the antenna. Since the columns are arranged symmetrically with respect to each other so as to receive substantially the same wind pressure, it is possible to cancel the wind pressure from the side surface of the antenna. According to a third aspect of the present invention, the wind pressure load in the direction substantially orthogonal to the radio wave arrival direction of the antenna and the wind pressure load in the direction parallel to the radio wave arrival direction of the antenna are formed in different shapes. The balance is improved and the rotation moment can be further reduced.

Since the wind pressure load of the balance means can be adjusted, the wind pressure load can be set to an appropriate level and the antenna can be flexibly changed. According to a fifth aspect of the present invention, the balance means is integrally formed in a direction substantially parallel to the direction of arrival of radio waves from the antenna and in a direction parallel to the direction.
Mass production with molds is possible and cost can be reduced. According to a sixth aspect of the present invention, since the balance means is separately formed in a direction parallel to a direction substantially orthogonal to the radio wave arrival direction of the antenna, unnecessary balance means can be removed, resulting in cost reduction. . According to a seventh aspect of the present invention, since the antenna is disposed at a position symmetrical with respect to the support column so as to be further retracted by the thickness of the antenna so as to receive the wind pressure applied from the radio wave arrival direction of the antenna and the wind pressure applied from the side surface substantially equally, Wind pressure load from the azimuth can be offset. Claim 8
Since the balance means is made of a dielectric material having a high radio wave transmittance, unnecessary reflection can be suppressed, a rotation moment due to wind pressure loading can be prevented, and the weight can be realized.
