Description

Technical Field

[0001] This utility model relates to the field of snow cover detection technology, and in particular to a snow cover depth detection device. Background Technology

[0002] Snow detection utilizes reflected signals from navigation systems such as GNSS-R, and is mainly used for monitoring sea level height, wind speed and direction, sea ice height, and snow depth. GNSS-R is based on the radio physics microwave signal scattering theory, and analyzes the changes in parameters such as intensity, frequency, phase, and polarization direction between the reflected signal of the target object and the direct GNSS signal to perform detection.

[0003] A search revealed a snow depth detection device (CN221666896U), which uses an ice-breaking mechanism to break up the ice shell on the snow surface during snow depth detection, thereby reducing the impact of the ice shell on the detection results. The device includes a moving mechanism, a lifting mechanism, a rotating mechanism, an extension mechanism, a clamping mechanism, and an ice-breaking mechanism. The lifting mechanism, rotating mechanism, and extension mechanism are all mounted on the moving mechanism and the extension mechanism, respectively. The clamping mechanism and the ice-breaking mechanism are also mounted on the extension mechanism. The moving mechanism moves, the lifting mechanism moves up and down, the rotating mechanism rotates, the extension mechanism extends, the clamping mechanism clamps, and the ice-breaking mechanism breaks the ice.

[0004] When this technical solution is in use, the detection device is clamped and fixed by the movement of two side plates. When the device is in use, the ice-breaking mechanism needs to break the ice. The shaking generated by breaking the ice will be transmitted to the side plates through the extension mechanism, causing the side plates and the detection device to shake. Since the side plates can only clamp and fix the outer wall of the detection device, the detection device will deflect between itself and the side plates due to the shaking, causing the angle of the detection device to change and affecting the detection accuracy.

[0005] Therefore, we propose a snow depth detection device. Utility Model Content

[0006] The present invention mainly solves the technical problem that the existing technology can only clamp and fix the detection device to the outer wall, and the detection device will deflect under shaking, thus affecting the detection accuracy, and provides a snow depth detection device.

[0008] Furthermore, the side clamping plate is annular and adapted to the outer wall of the detection device body. The extrusion plate is fixedly connected to the top of the wall opposite to the side clamping plate. The upper clamping plate is frustum-shaped. A telescopic rod and a return spring are provided on the upper clamping plate and the wall opposite to the top of the clamping box. The cross section of the extrusion plate near the upper clamping plate is inclined, and the inclined parts of the upper clamping plate and the extrusion plate are in contact.

[0009] Furthermore, the sliding seat is fixedly connected to both ends of the clamping box, the extension rod is slidably connected to the inner wall of the sliding seat, the drive motor is fixedly connected to the side of the sliding seat away from the extension rod through the motor frame, the extension rod has a through threaded hole, and the adjusting screw is threadedly connected to the inner wall of the threaded hole.

[0010] Furthermore, the clamping box has limit grooves on both the upper and lower ends, and limit sliders are slidably connected to the inner walls of the limit grooves. The limit sliders are fixedly connected to the upper and lower ends of the side clamping plate.

[0011] Furthermore, a through hole is provided in the middle of the bottom of the clamping box, and an annular guide ring is provided at the bottom of the clamping box, with the top of the cross-section of the guide ring being inclined.

[0013] Furthermore, multiple linearly arranged fixing grooves are provided in the gap between the outer wall of the side clamping plate and the protective ring. Buffer balls are fixedly connected in the fixing grooves. The buffer balls are elastic, and one side of the buffer balls is in contact with the inner wall of the protective ring.

[0014] Beneficial effects

[0015] This invention provides a snow depth detection device. It has the following beneficial effects:

[0016] (1) The snow depth detection device can clamp and fix the upper and lower ends and side walls of the detection device body through the clamping mechanism, driving mechanism and upper clamping plate, so as to maintain the stability of the position of the detection device body and avoid the shaking of the clamping box during ice breaking when only the side wall of the detection device body is squeezed and fixed, which would cause the detection device body to deflect and thus affect the detection accuracy of the detection device body.

[0017] (2) The snow depth detection device, through the setting of the protective ring and buffer ball, can protect the detection device body through the elasticity of the protective ring, avoid the friction between the detection device body and the side clamping plate when the detection device body deflects, and avoid damage to the detection device body. Furthermore, the deformation of the protective ring and buffer ball under compression can buffer the stress of shaking, further preventing the detection device body from deflecting due to shaking and affecting the detection accuracy of the detection device body.

[0025] Example 1: A snow depth detection device, such as Figure 1As shown, the device includes a lifting mechanism 1, an extension mechanism 2 at the top of the lifting mechanism 1, and an ice-breaking mechanism 3 at the bottom of the tail end of the extension mechanism 2. (The bottom of the lifting mechanism 1 is equipped with a base, and the four corners of the base are equipped with wheels for movement. The top of the lifting mechanism 1 is equipped with a rotating mechanism, the extension mechanism 2 is located at the top of the rotating mechanism, the ice-breaking mechanism 3 contains a rotating shaft and an ice-breaking drill, the tail end of the extension mechanism 2 is equipped with a motor, the rotating shaft is located at the output end of the motor, and the ice-breaking drill is located at the bottom end of the rotating shaft in a circumferential position.) The part in parentheses represents the prior art, which will not be elaborated here. When it is needed, the lifting mechanism 1 is moved to a suitable position by the wheels at the bottom of the base and raised to a suitable height. Then, the rotating mechanism drives the ice-breaking mechanism 3 to rotate to the required angle. Finally, the motor drives the ice-breaking drill to rotate through the rotating shaft to break the ice.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, a clamping box 4 is fixedly connected to the outer wall of the tail end of the extension mechanism 2. The detection device body 5 is movably installed inside the clamping box 4. A clamping mechanism for clamping and fixing is provided inside the clamping box 4. The clamping mechanism includes side clamping plates 6 set on both sides of the inner wall of the clamping box 4 and an upper clamping plate 8 set at the top of the inner wall of the clamping box 4. The side clamping plates 6 and the upper clamping plate 8 clamp and fix the side wall and top of the detection device body 5.

[0027] The clamping box 4 is equipped with a drive mechanism at both ends for moving the side clamping plate 6. The drive mechanism includes a sliding seat 11 and an extension rod 12 disposed between the clamping box 4 and the side clamping plate 6. The extension rod 12 is slidably connected to the inner wall of the sliding seat 11. A drive motor 13 is disposed on the inner wall of the sliding seat 11. An adjusting screw 14 is disposed at the output end of the drive motor 13. The adjusting screw 14 is threadedly connected to the inner wall of the extension rod 12. By rotating the adjusting screw 14, the extension rod 12 is driven to slide in the sliding seat 11, thereby driving the side clamping plate 6 to move. A pressing plate 9 is disposed on the top of the outer wall of the side clamping plate 6 for driving the upper clamping plate 8 to move. By pressing the upper clamping plate 8 with the pressing plate 9, the upper clamping plate 8 is driven to move down and clamp and fix the top of the detection device body 5.

[0028] like Figure 3 and Figure 5 As shown, the side clamping plate 6 is arc-shaped and fits the outer wall of the detection device body 5. The extrusion plate 9 is fixedly connected to the top of the wall opposite to the side clamping plate 6. The upper clamping plate 8 is arc-shaped and made of elastic material at the bottom. The upper clamping plate 8 and the clamping box 4 are provided with a telescopic rod 15 and a return spring 16 on the top opposite wall. The return spring 16 is sleeved on the outer wall of the telescopic rod 15. The cross section of the extrusion plate 9 near the upper clamping plate 8 is inclined. The inclined parts of the upper clamping plate 8 and the extrusion plate 9 are in contact.

[0029] When the side clamping plate 6 moves, the pressing plate 9 moves synchronously with the side clamping plate 6. Due to the limiting force of the telescopic rod 15 on the upper clamping plate 8 and the elastic force of the return spring 16, the upper clamping plate 8 and the pressing plate 9 can be kept in contact. When the pressing plate 9 moves, it can press the inclined surface of the upper clamping plate 8 through its inclined part, causing the upper clamping plate 8 to move downward along the telescopic direction of the telescopic rod 15, so that it can move to the top of the detection device body 5 and clamp and fix the detection device body 5.

[0030] like Figure 4 As shown, the sliding seat 11 is fixedly connected to both ends of the clamping box 4, and the extension rod 12 is slidably connected to the inner wall of the sliding seat 11. The drive motor 13 is fixedly connected to the side of the sliding seat 11 away from the extension rod 12 through the motor frame. Both the sliding seat 11 and the extension rod 12 are rectangular structures to avoid deflection between the extension rod 12 and the sliding seat 11, which would affect the adjustment of the position of the extension rod 12. A through threaded hole is opened in the extension rod 12, and the adjusting screw 14 is threadedly connected to the inner wall of the threaded hole.

[0031] When it is necessary to move the side clamping plate 6 to clamp and fix the detection device body 5, the drive motors 13 on both sides are turned on. The start of the drive motors 13 can drive the adjusting screw 14 to rotate. The rotation of the adjusting screw 14 drives the extension rod 12 to slide in the sliding seat 11 through the threaded hole on the extension rod 12. Then, the movement of the extension rod 12 drives the side clamping plate 6 to move synchronously to clamp and fix the detection device body 5.

[0032] like Figure 3 As shown, the clamping box 4 has limit grooves on both the upper and lower ends. Limit sliders 10 are slidably connected to the inner wall of the limit grooves. The limit sliders 10 are fixedly connected to the upper and lower ends of the side clamping plate 6. The side clamping plate 6 is moved and limited by the sliding of the limit sliders 10 in the limit grooves.

[0033] A through hole is provided in the middle of the bottom of the clamping box 4. A ring-shaped guide ring 7 is provided at the bottom of the clamping box 4. A gap is provided between the guide ring 7 and the through hole for placing the detection device body 5. The guide ring 7 and the through hole are located on the same axis. The top of the cross-section of the guide ring 7 is inclined.

[0034] When it is necessary to clamp and fix the detection device body 5, the detection device body 5 is placed inside the guide ring 7. It can then enter the gap between the guide ring 7 and the through hole as guided by the inclined surface of the guide ring 7. The detection device body 5 detects the depth of the snow through the through hole at the bottom.

[0035] In summary, through the clamping mechanism, driving mechanism, and upper clamping plate 8, the detection device body 5 is placed at the bottom of the clamping box 4, which limits and fixes the bottom of the detection device body 5. The drive motor 13 starts and drives the extension rod 12 to move, which in turn drives the side clamping plate 6 to move and clamp and fix the outer wall of the detection device body 5. The pressing plate 9 presses the upper clamping plate 8, which moves the upper clamping plate 8 down to clamp and fix the top of the detection device body 5. Thus, the upper and lower ends and the side walls of the detection device body 5 can be clamped and fixed, keeping the position of the detection device body 5 stable. This avoids the shaking caused by the clamping box 4 during ice breaking when only the side walls of the detection device body 5 are pressed and fixed, which would cause the detection device body 5 to deflect and thus affect the detection accuracy of the detection device body 5.

[0036] like Figure 6 As shown, a protective ring 17 is provided at the inner ring of the side clamping plate 6. The protective ring 17 is made of multiple ring-shaped blocks with semi-circular cross-sections arranged in a circumferential pattern and fixedly connected to the inner ring of the side clamping plate 6. The protective ring 17 is made of elastic material.

[0037] Multiple linearly arranged fixing grooves are provided in the gap between the outer wall of the side clamping plate 6 and the protective ring 17. A buffer ball 18 is fixedly connected in the fixing groove. The buffer ball 18 is spherical and elastic, and one side of the buffer ball 18 is in contact with the inner wall of the protective ring 17.

[0038] When the side clamping plate 6 clamps and fixes the detection device body 5, the protective ring 17 on it contacts the outer wall of the detection device body 5. The outer wall of the detection device body 5 squeezes the protective ring 17, causing it to deform and fit against the outer wall of the detection device body 5. This protects the outer wall of the detection device body 5 from damage caused by friction with the side clamping plate 6 when the detection device body 5 deflects. Furthermore, the deformation of the protective ring 17 squeezes the buffer ball 18, and the deformation of the protective ring 17 and the buffer ball 18 buffers the stress when the detection device body 5 shakes, thus improving the stability of the detection device body 5.

[0039] By using the protective ring 17 and buffer ball 18, the elasticity of the protective ring 17 can protect the detection device body 5, preventing the detection device body 5 from being damaged by friction with the side clamping plate 6 when it deflects. Furthermore, the deformation of the protective ring 17 and buffer ball 18 under compression can buffer the stress of shaking, keeping the detection device body 5 fixed and stable, and further preventing the detection device body 5 from deflecting due to shaking, which would affect the detection accuracy of the detection device body 5.

[0040] The working principle of this utility model is as follows: When it is necessary to clamp and fix the detection device body 5, the detection device body 5 is placed in the gap between the guide ring 7 and the through hole. At this time, the drive motors 13 on both sides are turned on. The start of the drive motors 13 drives the adjusting screw 14 to rotate. The rotation of the adjusting screw 14 drives the extension rod 12 to slide in the sliding seat 11 through the threaded hole on the extension rod 12. Then, the movement of the extension rod 12 drives the side clamping plate 6 to move synchronously to clamp and fix the detection device body 5. When the side clamping plate 6 moves, the pressing plate 9 moves synchronously with the side clamping plate 6. The movement of the pressing plate 9 can press the inclined surface of the upper clamping plate 8 through its inclined part, bringing... The upper clamping plate 8 moves downward along the telescopic direction of the telescopic rod 15, and can move to the top of the detection device body 5 to clamp and fix the detection device body 5. The detection device body 5 detects the depth of snow accumulation through the through hole at the bottom. When the side clamping plate 6 clamps and fixes the detection device body 5, the protective ring 17 on it contacts the outer wall of the detection device body 5. The outer wall of the detection device body 5 can squeeze the protective ring 17, causing the protective ring 17 to deform and fit against the outer wall of the detection device body 5. The deformation of the protective ring 17 also squeezes the buffer ball 18. Then, the deformation of the protective ring 17 and the buffer ball 18 buffers the stress when the detection device body 5 shakes.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
