[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a snowfall measuring device for automatically measuring snowfall within a predetermined time, and particularly to a structure of a snow receiving plate for collecting snowfall samples for measuring snowfall.

[0002]

[Prior art]

 As a conventional device for automatically measuring the amount of snowfall, as shown in FIG. 2, it is possible to rotate 180 degrees in the horizontal axis direction by the support arm 3 in the middle of the pillar 1 standing on the ground, and both sides thereof. A snow receiving plate 2 is provided for collecting snowfall, and a light projecting unit 4 and a light receiving unit 5 for measuring the amount of snowfall are provided above the snow receiving plate 2 so that the snow receiving plate 2 receives light from the light projecting unit 4. The amount of snowfall is measured by detecting the incident angle changes of the reflected light from the surface and the snowfall sample surface at the light receiving part 5, and then the support arm 3 rotates the snowcover 2 by 180 degrees and the snowcover concerned. The heater 6 that heats both snowfall surfaces of 2 separately is provided, and the structure is used to remove the remaining snow. (Actual fair No. 4-9594)

Further, the snowfall measuring device filed by the applicant of the present application on the same date as the present application, as shown in FIG. 3, is capable of vertically moving up and down on the column 11 and being rotatable in the horizontal axis direction. The plate 12 is provided by the support arm 13 and the connecting part 14, and the distance measuring part 15 composed of an ultrasonic wave transmitter / receiver for measuring the amount of snowfall is provided above the plate 12, and before and after the elapse of a predetermined time by the timer 16. The data processing unit 17 detects and calculates the arrival time difference of the reflected wave from the surface of the snow plate 12 and the snowfall surface of the sound wave to measure the snowfall amount, and the data output unit 18 displays or records it. After the output of the above data, the snow reception plate 12 is rotated 90 degrees or more by the rotation of the support arm 13 by the control unit 19 such as a motor after the output of the above data, and the snow is removed by its own weight. The structure is prepared for measurement.

[0004]

However, in the former structure of removing snowfall in the above-mentioned conventional example, the snowfall removal of the snowfall after measuring the amount of snowfall on one surface of the snowboard 2 is performed by removing the snowboard 2 by 180 degrees. The surface is rotated once so that one side faces downward, and only one side is heated with a heater to melt the remaining snow. Therefore, even if the heating is applied to only one surface, the heating may affect the other snow-receiving surface close to it, especially in order to improve the accuracy of snowfall measurement like the latter. In the natural environment, snow collecting is performed, that is, the snow receiving plate 2 is set on the snow surface to measure and collect snow. However, in the case of this measuring device, the snow receiving plate 2 is buried in the snow. Melting the remaining snow by heating loses the natural environmental conditions of the surrounding area where snowfall is collected, and is difficult to apply to such measuring devices. The latter structure rotates the snow receiving plate 12 by 90 degrees or more and removes it by the weight of the snowfall. It depends on the material and surface treatment of the surface of the snow receiving plate 12, but There is a concern that it may not be excluded. The present invention was made to solve the above-mentioned conventional problems, and it is an object of the present invention to reliably eliminate snowfall on the snow receiving plate 2 and improve the accuracy of snowfall measurement. .

[0005]

[Means for Solving the Problems]

 The snowfall measuring device of the present invention displays or records the snowfall within a predetermined time based on the snow receiving plate, the distance measuring unit provided above the snow receiving plate, and the measurement result of the distance measuring unit. In a snowfall measuring device comprising a data output unit for controlling the snowfall and a control unit for driving the snowfall removing means of the snowboard, a snowfall having an edge portion for removing snowfall on the upper surface of the snowboard. A slide bar for exclusion is slidably provided.

[0006]

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an embodiment of a snow receiving plate according to the present invention. (A) is a partially cutaway perspective view, (b) is a front view showing the front plate of (a) with the front plate removed, and (c) is FIG. 7 is a partially enlarged view of a slide bar provided on the snow receiving plate. In FIG. 1, reference numeral 20 denotes a snow receiving plate, the details of which are as follows. Reference numeral 21 denotes a case on a box having a snow receiving plate 22 on the upper surface thereof and bearing portions 25 on both side plates 24 thereof, and 26 denotes a drive shaft whose both ends are pivotally supported by the bearing portion 25 of the side plate 24. A pair of sprockets 27a are provided at both ends thereof, and a gear 28 connected to a gear 30 of a motor 29 of a drive source is provided at an intermediate portion thereof. Reference numeral 31 is a shaft that makes a pair with the drive shaft 26, both ends of which are axially supported by the bearing portion 25 of the side plate 24, and a pair of sprockets 27b are provided at both end portions thereof similarly to the drive shaft 26. . Reference numeral 32 denotes a belt that is wound around each of the sprockets 27a and 27b of the drive shaft 26 and the shaft 31, and a slide bar 33 having edge portions 33a provided on both sides in the longitudinal direction is fixed to both belts 32 and 32. Has been done. A stopper 34 for the slide bar 33 is provided at each corner of the snow receiving portion 22.

Next, the operation of this embodiment will be described. Like the conventional snowfall measuring device, after the snowfall on the snow receiving plate has been measured, the snowfall on the snow receiving plate is removed in preparation for the next measurement. For example, a motor 29 is driven by a control signal (not shown) from the data processing unit, and the power of the motor rotates the drive shaft 26 by coupling the gears 30 and 28 to rotate the sprockets 27a at both ends thereof. Therefore, the slide bar 33 fixed to the pair of belts 32, 32 hung around the sprocket 27a and the sprocket 27b of the shaft 31 moves forward and backward on the snow receiving portion 22 as the belts 32, 32 move. It slides on. Since the slide bar 33 is provided over both front ends of the snow receiving plate 20 including the snow receiving portion 22 and the belts 32, 32, all snowfall is eliminated. In addition, it is also possible to widen the operation range by making a part of the slide bar 33, which abuts on the stopper 34, a part of the cut portion. Moreover, in order to surely remove the snowfall by the slide bar 33, the both sides thereof are the edge portions 33a as described above, but in order to increase the contact pressure with the snow receiving portion 22, the surface of the belt 32 is removed from the snow receiving portion 22. The structure will be such that the position is slightly lowered. Further, the operation of reversing the slide bar 33 in the front-rear direction is controlled by such a method that the switch is operated so as to be reversed when the slide bar 33 moves to the position where it abuts on the stopper 34.

Although the slide bar 33 is moved by using the belts 32 and 32 in this embodiment, a chain, a wire or the like may be used instead of the belt. Further, the shape of the slide bar 33 may be a height such that snow can be sufficiently removed, or a curved shape such that snowfall is easily caught. Further, although the explanation is given that the snow removal is performed only by the slide bar 33, the support arm 23 is rotated in the horizontal axis direction to remove the snow by the own weight of the snow, or simultaneously, the slide bar 33 is moved to remove the snow. With this configuration, snowfall can be eliminated more reliably.
