Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rotating structure made of a fluid suitable for use in decorations and monuments placed in parks, gardens, ponds, etc.

[0002]

[Prior Art]

 In the parks, gardens, etc., stone spheres as a monument and ornaments, and spheres placed on a base may be installed to entertain the public's eyes.

[0003]

[Problems to be solved by the device]

 Traditional monuments are installed in parks and other places and do not move, so there is more fun than appearance and is easy to get tired of.

Therefore, it is desired to develop not only a beautiful appearance but also a moving structure.

The present invention is to provide a rotating structure made of a fluid which has a special appearance and is beautiful, and which can be noticed by the public due to the movement caused by rotation.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the structure of the present invention comprises a base, a cylindrical pressure chamber formed downward in the center of the base, and rotatably disposed at the opening of the pressure chamber. And a fluid supply passage which is connected to the pressure chamber and is formed in the base in a tangential direction of the sphere. The sphere is formed of a material having a specific gravity of 1 or more, for example, stone material.

[0007]

[Action]

 When high-pressure fluid, such as water, is supplied from the fluid supply passage, the internal pressure of the pressure chamber rises and the sphere floats.

Since the fluid in the pressure chamber is guided from the tangential direction of the spherical body, it flows in the rotational direction in the pressure chamber and flows onto the base through the gap between the spherical body and the opening while applying a rotational force to the spherical body.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the rotary structure according to the present invention installed in a pond 6 in a park.

However, this rotating structure is preferably placed in a green space of a park, a home garden, a front door of a building, a rooftop, or other place where people gather, and is used as a so-called ornament or monument.

The rotating structure A is a rectangular, cubic or cylindrical base 1 made of stone, concrete, metal or the like, and a material having a specific gravity of 1 or more rotatably arranged on the base 1. For example, it is composed of a stone material, a metal material, or a sphere 4 made of these and a synthetic material of plastics.

A cylindrical pressure chamber 2 is formed downward in the center of the base 1, and the depth of the pressure chamber 2 is formed to be equal to or larger than the diameter of the spherical body 4, and the diameter of the opening 3 thereof. Also has a diameter equal to or preferably smaller than that of the sphere 4.

The sphere 4 is concentrically and rotatably abutted on the opening 3 of the pressure chamber 2 at rest.

The outer periphery of the sphere 4 is in contact with the opening 3 at the center or slightly below the center.

One or a plurality of pressure fluid supply passages 5, 5 are horizontally formed in the body of the base 1 in the tangential direction of the sphere 4, and the outlets of the fluid supply passages 5, 5 are pressure chambers 2 It is opened inside and the other inlet is connected via a pipe 7 to a pressure source such as a pump.

When a pressure fluid having an arbitrary pressure, for example, high-pressure water is supplied through the pipe 7 and the fluid supply passages 5 and 5, this water is introduced into the pressure chamber 2 and flows in the rotation direction in the pressure chamber 2. The overflowed water tries to flow on the base 1 through the opening 3.

Since water is forcibly introduced, the pressure chamber 2 has a high pressure, and the sphere 4 floats with the increased pressure.

At this time, since the specific gravity of the spherical body 1 is 1 or more, the spherical body 1 does not flow out together with water, and only slightly floats while balancing with the internal pressure of the pressure chamber 2.

When the sphere 4 floats, a small gap is formed between the sphere 4 and the opening 3, and the water 8 flows on the base 1 through this gap.

At this time, a rotational force is applied to the sphere 4 by the flow of water in the pressure chamber 2 in the rotation direction and the flow of water flowing along the rotation direction from the gap, and the sphere 4 rotates slowly because it does not float. . For this reason, the public pays attention to the rotation of a heavy sphere, and finds value in its appearance as well as its movement.

The rotation speed of the sphere 4 can be changed by the supply pressure, the size of the pressure chamber 2, and the size of the gap between the sphere 4 and the opening 3.

As shown in FIG. 3, as the surface processing of the sphere 4 and the processing of the opening 3 are more precise and closer to a perfect circle, the water 8 flows smoothly on the base 1, and the rotation of the sphere 4 and the water flow are combined. Give beauty.

On the other hand, when the surface of the sphere 4 is formed to be slightly rough, the size of the gap between the sphere 4 and the opening 3 changes during the rotation of the sphere 4, and the high-pressure water is directed to the arrow 8a as shown in FIG. As shown, it can be sprayed upward, horizontally, etc. from this gap to give another beauty.

[0025]

[Effect of the device]

 The present invention has the following effects.

1) When high-pressure water is supplied to the pressure chamber, the sphere arranged above the pressure chamber rotates while floating. Therefore, due to the beauty of the sphere and the movement of the sphere, it is easy to catch the eyes of the public when it is used as an ornament or monument, and it is interesting and never boring.

2) The size of the gap between the sphere and the opening of the pressure chamber can be changed by precisely processing the surface of the sphere into a perfect circle or roughing it, and the effluent flows out from this gap. Changes can be made to the flow of pressure fluid.
