According to the present invention, the sensor part is structurally supported stably, and by measuring the amount of snow by the method of directly touching the snow accumulated by the sensor part, accurate measurement is possible.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown below in FIG. 2, the snow meter 20 according to the present invention basically includes a sensor unit 100 for measuring snow amount, and a driving unit 200 for driving the sensor unit 100 to move in the vertical direction. It is configured to include).

In particular, the snow meter 20 according to the present invention may be characterized in that the driving unit 200 takes the following structure.

That is, the driving unit 200 is a motor 210 for generating a driving force, a screw member 220 is rotated about the vertical direction by the motor 210 and the screw member 220 is formed on the outer peripheral surface, the screw member 220 The screw unit 222 is screwed and moved along the screw member 220 by the rotation of the screw member 220 may be configured to include a moving member 230, the sensor unit 100 is installed.

Therefore, the sensor unit 100 is installed on the moving member 230 and moved along the screw member 220 to sense the height of the snow 1 directly stacked at the height of the snow 1 in which the sensor 100 is stacked. Since the snow amount can be measured, the effect that accurate measurement is possible can be acquired.

In particular, since the sensor unit 100 is firmly supported by the screw member 220 instead of the chain or the belt, the sensor unit 100 can sense the snow 1 accumulated in a stable posture without shaking by the wind. As a result, accurate measurement can be obtained.

Here, the moving member 230 is a screw portion 242 is formed to be screwed to the screw portion 222 of the screw member 220 and the threaded portion member 240 is coupled so that the sensor unit 100 is integrally behaved, The screw forming member 240 may be configured to include a guide member 250 to guide the linear movement along the screw member 220.

That is, the screw forming member 240 may be moved along the screw member 220 by screwing with the screw member 220, the screw forming member 240 by the guide member 250 screw member 220 By being constrained to rotate about, the sensor unit 100 along with the screw forming member 240 may be linearly moved along the screw member 220.

Screw forming member 240 may take a variety of structures, it may be more preferable to take a ring shape that is fitted to the outside of the screw member 220 for a firm and stable coupling with the screw member 220.

The guide member 250 may take a variety of structures, but includes at least one guide rod 252 installed in parallel with the screw member 220 and fitted with the screw forming member 240 or the sensor unit 100 to be movable. It is more preferable in terms of being configured such that it can be implemented in a simple structure, and can be guided firmly and stably.

Only one guide rod 252 may be provided, but two or more guide rods 252 may be provided for structural stability.

The sensor unit 100 may take a variety of structures, but it may be more effective to take a structure that can measure the amount of snow while directly touching the accumulated snow from the upper side of the stacked snow as follows.

That is, the method of measuring the height of the eye by touching the eye 1 directly accumulated by the sensor is not an indirect and complicated method of measuring snow quantity by radiating light waves, ultrasonic waves, etc. from the upper surface of the eye 1 accumulated as in the prior art. Drunk.

Therefore, as in the prior art, there is no fear of local settlement due to heat caused by light waves, ultrasonic waves, and the like, and the influence of irregular reflection angles and scattering phenomena of light waves and ultrasonic waves can be eliminated. Since it can be prevented, the effect that accurate measurement is possible can be obtained.

In addition, since the height of the accumulated snow 1 can be sensed directly, it is possible to obtain the effect that the calculation of the amount of snow can be made simple.

In addition, since the sensor unit 100 is movable in the vertical direction by the driving unit 200, even if the height of the snow 1 accumulated with the passage of time continues to increase, it is possible to obtain the effect that the continuous measurement is possible. .

Furthermore, the sensor unit 100 may be more preferably installed in the sensor support 270 protruding from the screw forming member 240 to a predetermined length as follows.

That is, the heat due to driving of the driving unit 200 affects the surrounding eyes to some extent, and the snow height around the screw member 220 is measured to be relatively low.

However, in the present invention, since the measurement point of the sensor unit 100 may be moved away from the periphery of the screw member 220 by the sensor support so as not to be affected by the heat dissipated from the snow level meter 20, the actual eye height is increased. The measurement can be performed, and the effect of the measurement accuracy can be further improved.

On the other hand, the present invention forms the appearance of the snow meter 20, the case 300 is formed with an opening 302 so that the sensor unit 100 is projected to the outside to measure the height of the snow (1) accumulated on the outside It may be characterized in that it further comprises a.

That is, since the driving unit 200 may be protected by the case 300, the driving unit 200 may be prevented from being contaminated by snow or dust, and the driving limit of the driving unit 200 may be prevented due to freezing or jamming. The effect can be prevented.

Here, the opening 302 of the case 300 is formed long in the vertical direction for the vertical movement of the sensor unit 100, but may take the structure always open as a whole, although not shown, the upper and lower sides of the sensor unit 100 Portions other than the protruding portion of the sensor unit 100 may be shielded by a shielding member or the like, which may be moved up or down depending on the movement.

As illustrated in FIGS. 2 to 5 by the snow meter 20 according to the present invention, the snow amount measured by sensing the height of the snow 1 accumulated at one measurement point by one sensor unit 100 is measured. And it may be configured to sense the height of the snow (1) accumulated at two or more measurement points for more accurate measurement.

In the latter case, as shown in FIGS. 2 to 5, two or more snow meter 20 provided with one sensor unit 100 may be installed in the enclosure 10. However, in order to install two or more snow gauges 20, the size of the enclosure becomes very large, the equipment burden caused by the installation of two or more snow gauges 20, measurement by two or more snow gauges 20 Problems with the data can be generated.

Therefore, as shown in FIGS. 6 to 8, two or more sensor units 100 are provided in one snow meter 20, so that the snow amount can be measured at two or more measurement points with one snow meter 20. It can take advantage of that.

For a simpler structure, the two or more sensor units 100 are integrally driven by one driving unit 200, so that each sensor unit 100 can move relative to the driving unit 200 in the vertical direction. More preferably 200).

For example, the sensor units 100A and 100B, which are A and B, are initially moved downward by the driving unit 200 on the same height line. Even though the A sensor unit 100A first touches the eye, the driving unit 200 is moved. Continues to be driven until the B sensor unit 100B touches the eye, as shown by a dotted line in FIG. 7, the A sensor unit 100A has a B sensor due to a failure due to touch with the stacked eye 1. It is located on the upper side relative to the part 100B.

At this time, it may be configured to measure the sensing height of each of the two or more sensor unit 100, more simply may be configured as follows.

That is, by sensing the height of the eye by the lowermost sensor unit 100 of the two or more sensor units 100, and the displacement (L) of the two or more sensor units 100, this displacement value is measured for each sensor unit 100. The height of the eye by each sensing unit can be measured by reflecting the height of the eye by

For example, as shown in FIG. 7, when the A sensor unit 100A is positioned above the B sensor unit 100B among the A and B sensor units 100A and 100B, the driving unit 200 may be driven. The height of the B sensor part 100B becomes the height of the snow 1 accumulated by the B sensor part 100B, and the height of the B sensor part 100B is the height of the A sensor part 100A and the B sensor part 100B. It can be the sum of the displacements (L).

In this way, if the height of the eye is measured by the two or more sensor units 100, by calculating the average value of the measurement result, it is possible to obtain an effect that a more accurate amount of snow can be measured.

The displacement L of the two or more sensor units 100 may be implemented by the displacement sensing unit 106 of various methods such as sensing the position of each sensor unit 100 using light waves, ultrasonic waves, or the like as shown. Can be.

On the other hand, for structural stabilization of the two or more sensor unit 100, as shown in Figures 6 to 8 may further include an elastic member 102 for supporting each of the sensor unit 100 by the elastic force.

In addition, it may further include a sensor guide unit 104 for guiding the two or more sensor unit 100 so that the relative movement of the two or more sensor unit 100 is possible only in a straight line in the vertical direction.

The sensor guide part 104 may have various structures, and as an example, an opening part which is fixed to the screw forming member 240 and opened so that the sensor part 100 protrudes and moves in the vertical direction relative to each other. It is possible to take the structure of the case 104B in which 104A) is formed.

Since the above has been described only with respect to some of the preferred embodiments that can be implemented by the present invention, the scope of the present invention, as is well known, should not be construed as limited to the above embodiments, the present invention described above It will be said that both the technical idea and the technical idea which together with the base are included in the scope of the present invention.
