Description

Technical Field

[0001] This utility model relates to the field of radon soil detection, specifically a radon sampler. Background Technology

[0002] A radon meter is an instrument used to detect the concentration of radon gas in the environment. Radon is a colorless, odorless, and tasteless radioactive gas produced by the decay of radioactive elements such as uranium and thorium in the Earth's crust. Long-term exposure to high concentrations of radon gas increases the risk of lung cancer; therefore, radon meters play an important role in environmental monitoring, building safety assessments, and other fields.

[0003] To facilitate the detection and treatment of radon concentration in soil, it is often necessary to set up a sampler to take samples from the soil. However, current samplers cannot take samples from different depths sequentially, which affects their usability. Utility Model Content

A guide cylinder is located at the center of the support frame, and a rotating rod is rotatably mounted on the top of the support frame. A rotation drive assembly for driving the rotating rod is mounted on the support frame. A rotating disk is located at the bottom of the rotating rod, and several support frames are fixedly arranged at equal intervals on the outer side of the rotating disk. A second motor is mounted on the top of one support frame, and a first screw is mounted on the motor shaft of the second motor. The bottom of the first screw is rotatably connected to the support frame, and a first sliding plate is threaded onto the first screw. The first sliding plate is slidably connected to the support frame and has a drilling assembly mounted on it.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model drives a rotating rod to rotate via a rotation drive assembly, which in turn drives a rotating disk to rotate, and the rotating disk drives a support frame to rotate. This allows the drilling assembly and sampling assembly to be rotated sequentially to the top of the guide cylinder for drilling and sampling, thus facilitating soil sampling at different depths and allowing for convenient sampling of radon concentration in the soil.

A rotating disk 12 is provided at the bottom of the rotating rod 8. Several support frames 13 are fixedly arranged at equal intervals on the outer side of the rotating disk 12. A second motor 14 is provided at the top of one end of each support frame 13. A first screw 15 is mounted on the motor shaft of the machine 14. The bottom of the first screw 15 is rotatably connected to the support frame 13. A first sliding plate 16 is threadedly connected to the first screw 15. The first sliding plate 16 is slidably connected to the support frame 13, and a drilling assembly is mounted on the first sliding plate 16. A third motor 19 is fixedly mounted on the support frame 13. A second screw 20 is mounted on the motor shaft of the third motor 19. The bottom of the second screw 20 is rotatably connected to the support frame 13. A second sliding plate 21 is threadedly connected to the second screw 20, and a sampling assembly is mounted on the second sliding plate 21.

[0021] This invention uses a rotation drive assembly to drive a rotating rod 8 to rotate, which in turn drives a rotating disk 12 to rotate. The rotating disk 12 then drives a support frame 13 to rotate, thereby rotating the drilling assembly to the top of the guide cylinder 7. A second motor 14 then drives a first screw 15 to rotate, which in turn drives a threaded sliding plate 16 to move downwards. The drilling assembly passes through the guide cylinder 7 and moves downwards to drill holes in the soil. The rotation drive assembly then drives each support frame 13 to rotate to one side of the guide cylinder 7. A third motor 19 then drives a second screw 20 to rotate, which in turn drives a second sliding plate 21 to move downwards. The second sliding plate 21 then drives a sampling assembly into the borehole, facilitating soil sampling.

[0022] See Figure 1 In one embodiment of this utility model, the rolling assembly includes a support leg 2 fixedly connected to the bottom of the support frame 1. A roller 3 is provided at the bottom of the support leg 2, and a brake 4 is provided at the outer end of the roller 3.

[0023] See Figure 1 In one embodiment of this utility model, a pair of handrails 5 are symmetrically arranged on the side wall of the support frame 1, and a handle 6 is provided on the top of the handrails 5. The arrangement of the handrails 5 and the handle 6 can facilitate the movement and handling of the sampler.

[0024] See Figure 2 In one embodiment of this utility model, the rotation drive assembly includes a first motor 9 fixedly connected to the support frame 1. A drive gear 10 is mounted on the motor shaft of the first motor 9, and a driven gear 11 is meshed on the drive gear 10. The driven gear 11 is connected to the rotating rod 8. When the first motor 9 works, the first motor 9 drives the drive gear 10 to rotate the meshed driven gear 11. The driven gear 11 can drive the rotating rod 8 to perform rotational orientation adjustment.

[0025] See Figure 3 In one embodiment of the present invention, the drilling assembly includes a drilling motor 17 fixedly connected to the top of the first sliding plate 16, and a drill rod 18 is provided at the bottom of the drilling motor 17.

The mounting frame 23 is driven to move downward by the telescopic rod 22, and the sampling cylinder 25 is driven to rotate by the rotating motor 24 to achieve rotational sampling of the soil at the bottom of the borehole.

[0027] Working principle: This utility model uses the handle 5 and the handle 6 to push the sampler to the sampling position. The first motor 9 drives the driving gear 10, which in turn drives the meshing driven gear 11. The driven gear 11 drives the rotating rod 8, which in turn drives the support frame 13 to rotate and adjust. The support frame 13 drives the drilling assembly to the top of the guide cylinder 7. The second motor 14 then drives the first screw 15 to rotate. The first screw 15 drives the threaded sliding plate 16 to move downwards. During the downward movement of the first sliding plate 16, the drilling motor 17 drives the drill rod 18 to rotate. The drill rod 18 performs drilling on the soil. After drilling, the rotating rod 8 is driven to rotate by the rotation drive assembly. The rotating rod 8 drives the support frame 13 to rotate synchronously. The support frame 13 drives the sampling assembly to rotate to the top of the guide cylinder 7. The third motor 19 works and drives the second screw 20 to rotate. The second screw 20 drives the threaded second sliding plate 21 to move downward. In conjunction with the telescopic rod 22, the mounting frame 23 moves downward. The rotating motor 24 drives the sampling cylinder 25 to perform rotational sampling on the soil inside the borehole, which facilitates the detection and processing of radon concentration in the soil.
