Therefore, by monitoring the thickness of snow and ice on the road surface and improving the level of traffic management, the above disasters can be avoided. Utility Model Content

[0028] See attached Figure 1 and 2 , Embodiment 1 provides a ground snow and ice thickness detection device, which is applied in the following scenarios: airport runways and outer edges of mountain roads.

[0029] A ground snow and ice thickness detection device comprises an outer cylinder 4, which is buried in the monitored road surface, an inner cylinder 3 is arranged in the outer cylinder 4, and the inner cylinder 3 can be removed from the outer cylinder 4. A lifting mechanism 1 and a circuit board 11 are arranged inside the inner cylinder 3. The lifting mechanism 1 pushes the inner cylinder 3 to move up and down inside the outer cylinder 4. A stroke displacement sensor is arranged on the lifting mechanism 1 to measure the stroke of the lifting mechanism 1; a battery compartment 14 is arranged on the top of the inner cylinder 3, a sensor support arm 7 is arranged on the top of the battery compartment 14, and a sensor housing 16 is arranged at the end of the sensor support arm 7. A snow layer detection sensor 5 and an ice layer detection sensor 6 are arranged in the sensor housing 16. The stroke displacement sensor, the snow layer detection sensor 5 and the ice layer detection sensor 6 are all connected to the circuit board 11. The snow layer detection sensor 5 is used to measure the snow layer thickness, and the ice layer detection sensor 6 is used to detect the ice layer thickness; a battery is arranged in the battery compartment 14, and the battery supplies power to the lifting mechanism, the lifting stroke sensor, the snow layer detection sensor 5 and the ice layer detection sensor 6.

[0030] The snow layer detection sensor 5 is a non-contact distance measuring sensor, which is installed at the bottom of the sensor housing 16. For example, ultrasonic wave or radar.

[0031] The ice layer detection sensor 6 is a displacement sensor installed at the bottom of the sensor housing 16. Figure 4In this embodiment, the ice layer detection sensor 6 comprises an ice-contacting cone 17, an ice-contacting cone sliding cavity 18, an ice-contacting cone sliding rod 19 and an ice-contacting sensor 20. The ice-contacting cone sliding cavity 18 is provided in the sensor housing 16. The ice-contacting cone sliding rod 19 is slidably arranged in the ice-contacting cone sliding cavity 18. A card table is provided on the top of the ice-contacting cone sliding rod 19 and matches and contacts with the ice-contacting sensor 20. The bottom of the ice-contacting cone sliding rod 19 is the ice-contacting cone 17. The ice-contacting sensor 20 is connected to the circuit board 11. The card table on the top of the ice-contacting cone sliding rod 19 prevents the ice-contacting cone sliding rod 19 from falling off from below.

[0032] See attached Figure 2 and 3 An outer shield 23 is provided on the outer side of the upper part of the inner cylinder 3, and the outer shield bottom flange 21 of the outer shield 23 is fixed on the outer cylinder top flange 30 of the outer cylinder 4, forming a closed shell as a whole to cover the inner cylinder 3, and a slide groove 24 is provided on the side wall of the outer shield 23, and the top of the slide groove 24 is inclined to one side, and the sensor support arm 7 extends out of the outer shield 23 from the slide groove 24.

[0033] When the sensor support arm 7 slides to the top of the slide slot 24, the top of the slide slot 24 tilts, and the sensor support arm 7 drives the inner cylinder 3 to rotate sideways, and the battery compartment 14 and the electric pull rod 8 and other components in the inner cylinder 3 rotate accordingly. Since the counterweight 12 is movably connected and plugged with the inner cylinder 3, the counterweight 12 does not move when the inner cylinder 3 rotates.

[0034] When it snows, due to the obstruction of the sensor support arm 7 and the sensor housing 16, there will be less snow under the sensor support arm 7 and the sensor housing 16, resulting in inaccurate measurement data. Therefore, the utility model sets the top of the slide 24 to an inclined state. When the sensor support arm 7 rises to the top of the slide 24, it will turn sideways, and the sensor support arm and the sensor housing 16 will bypass the blocked position, so that the snow layer detection sensor 5 and the ice layer detection sensor 6 can accurately measure.

[0035] The height of the slide groove 24 on the outer shield 23 allows the sensor support arm 7 to reach the highest position. The bottom edge of the outer shield 23 is provided with an outer shield bottom flange 21, and the outer shield bottom flange 21 is fixed to the flange on the upper edge of the outer cylinder 4 for fixing to the ground with screws, forming a protective shell as a whole to prevent rainwater from entering.

[0037] See attached Figure 1The lifting mechanism 1 includes an electric pull rod 8, a counterweight 12 and a bearing 13, and the stroke displacement sensor is a rope displacement sensor 9; an opening is provided at the bottom of the inner cylinder 3, and the counterweight 12 is inserted and arranged at the opening. A bearing 13 is provided on the counterweight 12, and the rope displacement sensor 9 is fixed inside the inner cylinder 3. The top end of the electric pull rod 8 is connected to the rope displacement sensor 9, and the bottom end of the electric pull rod 8 is connected to the bearing 13. The rope of the rope displacement sensor 9 is connected to the rope displacement sensor frame 10, and the rope displacement sensor frame 10 is installed at the lower part of the push rod of the electric pull rod 8, and the rope displacement sensor 9 is connected to the circuit board 11.

[0038] In this embodiment, the counterweight 12 is a heavy hammer.

[0039] See attached Figure 5 and 6 Embodiment 2. In order to cope with extreme weather, such as blizzard weather, etc., an outer protective cover 23 can be added on the basis of the ground snow and ice thickness detection device in Embodiment 1. An L-shaped vertical pole 25 is provided on the top of the outer protective cover 23 or on the road surface next to the outer protective cover. The end of the top cross bar of the L-shaped vertical pole 25 is matched with a radar ranging sensor 26. A flange 27 is provided at the bottom of the L-shaped vertical pole 25. The flange 27 fixes the L-shaped vertical pole 25 to the top of the outer protective cover 23 or on the road surface next to the outer protective cover 23. The radar ranging sensor 26 is connected to the circuit board 11 through a cable 29.

[0040] See attached Figure 7 A solar power supply system 28 is installed on the L-shaped pole 25, and the solar power supply system 28 supplies power to the radar ranging sensor 26. The solar power supply system 28 includes a solar panel, and the angle between the solar panel and the ground is 60 degrees, so as to facilitate the natural sliding of snow in winter.

[0041] The method of using the utility model comprises the following steps:

[0042] ① Drill a hole on the monitored ground and install the ground snow and ice thickness detection device into the hole; at this time, the sensor support arm 7 extends outward, and the snow layer detection sensor 5 and the ice layer detection sensor 6 on the sensor housing 16 face the monitored road surface;

[0043] ② By measuring the highest point of the electric pull rod 8 at the inner cylinder 3, the upper limit value of the pull rope displacement sensor 9 is set, and the distance between the non-contact distance measurement sensor and the ground is calibrated at the same time; the inner cylinder 3 is moved downward by the electric pull rod 8, and the inner cylinder 3 drives the sensor support arm 7 and the sensor housing 16 to move downward, the ice-contacting cone 17 at the bottom of the ice-contacting cone slide bar 19 contacts the ground and is pressed, the ice-contacting cone slide bar 19 moves upward, and the card table 22 at the top of the ice-contacting cone slide bar 19 contacts the ice-contacting sensor 20, so that the action of the ice-contacting sensor 20 is set to the lower limit value of the pull rope displacement sensor 9, and the ground is the distance measurement reference point;

[0044] ③ When it is necessary to measure the thickness of the snow and ice layers on the monitored road surface, the non-contact ranging sensor measures the thickness of the snow layer on the ground; the electric pull rod 8 moves the inner cylinder 3 downward, and the inner cylinder 3 drives the sensor support arm 7 and the sensor housing 16 to move downward, and the ice-contacting cone 17 at the bottom of the ice-contacting cone slide 19 is inserted into the snow layer until it contacts the ice surface and is pressed, and the top card platform 22 of the ice-contacting cone slide 19 contacts the ice-contacting sensor 20, and the ice-contacting sensor 20 transmits a signal to the circuit board 11, and the electric pull rod 8 stops moving, and the pull rope displacement sensor 9 measures the stroke of the electric pull rod 8, transmits the signal to the circuit board 11, and calculates the thickness of the ice layer.

[0045] ④ After it snows, due to the obstruction of the sensor support arm 7 and the sensor housing 16, there will be less snow under the sensor support arm 7 and the sensor housing 16, resulting in inaccurate measurement data. Therefore, the utility model sets the top of the slide 24 to an inclined state. When the sensor support arm 7 rises to the top of the slide 24, it will turn sideways, and the sensor support arm and the sensor housing 16 will bypass the blocked position, so that the snow layer detection sensor 5 and the ice layer detection sensor 6 can accurately measure.

[0046] ⑤ When used on mountain roads, in order to cope with the thick snow layer in blizzards, an L-shaped pole 25 can also be installed. The L-shaped pole 25 is set on the top of the outer shield 23 or on the road surface next to the outer shield 23. The end of the top cross bar of the L-shaped pole 25 is matched with a radar ranging sensor 26. The radar ranging sensor 26 is connected to the circuit board 11 in the inner tube 3 via a cable. The radar ranging sensor 26 has a range of not less than 8 meters and a beam angle of not more than 8 degrees. It can accurately monitor the snow layer several meters thick on mountain roads.
