[0031] like Figures 1 to 7 As shown, the rotary drive assembly 2 is arranged on the cross-shaped substrate 1, and the rotary drive assembly 2 includes a middle disc 201, a drilling motor 202, a gear 203, a gear ring 204 and a motor seat 205. The middle disc 201 is rotatably engaged in the cross-shaped substrate 1, the motor seat 205 is fixed below the cross-shaped substrate 1, the drilling motor 202 is fixed on the motor seat 205, the gear 203 is fixed on the output end of the drilling motor 202, and the gear ring 204 is fixed on the middle disc 201, and the gear ring 204 is meshed with the gear 203.

[0032] like Figures 1 to 7As shown, the depth control component 3 includes a lifting cylinder 301, a top plate 302, an upper disc 303 and a plurality of transmission rods 304. The lifting cylinder 301 is fixed on the cross-shaped base plate 1, the top plate 302 is fixed on the telescopic end of the lifting cylinder 301, the upper disc 303 is rotatably engaged in the top plate 302, the top ends of the plurality of transmission rods 304 are fixedly connected to the upper disc 303, the plurality of transmission rods 304 are slidably connected to the middle disc 201, and the bottom ends of the plurality of transmission rods 304 are fixedly connected to the circular semiconductor refrigeration plate 4.

[0033] like Figures 1 to 7 As shown, the sampling cylinder assembly 5 also includes a curved handle 511. The sampling cylinder assembly 5 is provided with no less than three groups. A hooked electronic scale 6 is fixedly provided under the middle disc 201 and the upper disc 303. The curved handle 511 is detachably connected to the hooked electronic scale 6.

[0034] like Figures 1 to 7 As shown, a plurality of heat dissipation fins 401 are fixedly provided above the circular semiconductor cooling plate 4 .

[0035] like Figures 1 to 7 As shown, a ground pile 101 is fixed on the cross-shaped base plate 1 . Example

[0036] When inspecting the safety of the site, staff first drive ground stakes 101 into the snow around the sampling point to maintain the overall stability of the device. They then power the circular semiconductor cooling chip 4, keeping the sampling tube assembly 5, which fits snugly beneath it, at a lower temperature. This prevents frictional heat from overheating during subsequent drilling and sampling, further preventing the snow sample from melting directly inside the sampling tube assembly 5, which could affect the accuracy of the moisture content and safety test results.

[0037] The operator controls the drilling motor 202 to rotate continuously in one direction, while simultaneously controlling the lifting cylinder 301 to reduce its extension and retraction. The contraction of the lifting cylinder 301 drives the top plate 302, the upper disc 303, and the transmission rod 304 downward, causing the sampling barrel assembly 5 below the transmission rod 304 to move downward and into deeper snow layers. The rotation of the drilling motor 202 drives the middle disc 201 through the gear 203 and the gear ring 204. The sliding connection between the middle disc 201 and the transmission rod 304 drives the upper disc 303, the circular semiconductor cooling plate 4 below it, and the sampling barrel assembly 5 to rotate continuously. This allows the drill bit 504 at the bottom of the sampling barrel assembly 5 to rotate downward, enabling drilling and sampling of harder and deeper snow layers.

[0038] As the sampling cylinder assembly 5 rotates and moves downward, the sampling principle is as follows: the sampling slot 505 of the lower cone bottom shell 502 is interconnected with the sampling slot 505 of the inner cone bottom shell 503. As the sampling cylinder moves downward, the snow layer can be squeezed and sent into the upper cylinder 501. After reaching the preset sampling depth, the staff controls the movement of the electric-controlled rail trolley 508, which pulls the opening and closing connecting rod 509 and the inner cone bottom shell 503 through the arc-shaped idle track 507, causing the sampling slot 505 on the inner cone bottom shell 503 to rotate, gradually shifting the position of the sampling slot 505 on the lower cone bottom shell 502, and finally sealing the bottom of the upper cylinder 501.

[0039] After the upper cylinder 501 is sealed, the operator turns off the drilling motor 202 and controls the lifting cylinder 301 to extend, causing the top plate 302, transmission rod 304, and sampling tube assembly 5 to move upward. Once the sampling tube assembly 5 is above ground, the operator can unscrew the threaded connection between the threaded sleeve 510 and the circular semiconductor cooling plate 4 by twisting. The operator then hangs the curved handle 511 of the newly removed sampling tube assembly 5 on the hooked electronic scale 6 below the upper disc 303 to measure the weight of the unmelted snow sample. Subsequently, the curved handle 511 is hung on the hooked electronic scale 6 below the middle disc 201. The hot end of the circular semiconductor cooling plate 4 is used to heat the snow sample in the sampling tube assembly 5, causing it to melt rapidly. The weight of the melted snow sample is then measured on the hooked electronic scale 6. Finally, the operator can calculate the moisture content of the snow sample based on these two weight measurements and assess the safety of the ski resort.

[0040] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
