Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, and more specifically, to a testing device for soil pollution prevention and control. Background Technology

[0002] Soil pollution not only damages the ecological environment but also poses a direct threat to human health through the food chain. Crops grown in contaminated soil may absorb and accumulate harmful substances, potentially causing various diseases in humans, such as cancer, nervous system disorders, and immune system diseases. Therefore, timely and accurate detection of soil pollution is crucial for implementing effective prevention and control measures and protecting the ecological environment and human health.

[0003] A search revealed that patent application CN201921469884.X discloses a detection device for soil pollution prevention. The lower limiting ring has symmetrically arranged grooves on both sides of its upper end face. These grooves engage with a lower fixing block on the lower side of a fixing rod. An upper fixing block is fixed to the upper end of the fixing rod, and this upper fixing block engages with grooves on both sides of the lower end face of an upper fixing plate. A screw hole is located in the middle of the upper fixing plate, and an adjusting rod is engaged inside the screw hole. The adjusting rod extends through the screw hole to the lower side of the upper fixing plate, and an electromagnet is fixed to the lower side of the adjusting rod. By adding the adjusting rod, the threads on the side of the adjusting rod engage with a through hole in the middle of the upper fixing plate. This design facilitates adjusting the distance between the adjusting rod and the lower limiting ring by rotating the adjusting rod, and it also facilitates adjusting the height of the test cone according to the actual needs of the detection. However, it still has the following drawbacks:

[0004] (1) The existing detection devices are not convenient to insert the test cone into the soil at different depths, so it is inconvenient to detect soil at different depths;

[0005] (2) In the existing technology, soil needs to be dug manually to test the soil, which results in low testing efficiency and the testing device is inconvenient to move flexibly.

[0006] Therefore, we have made improvements to this and proposed a detection device for soil pollution prevention and control. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this embodiment proposes a detection device for soil pollution prevention and control, including a frame 1, a ground insertion mechanism 2 on the frame 1, a mounting plate 3 on the upper side of the frame 1, a lifting mechanism 4 on the frame 1 for adjusting the height of the mounting plate 3, a mounting frame 5 on the outer side of the mounting plate 3, a reversing mechanism 6 between the mounting plate 3 and the mounting frame 5, a first motor 7 fixedly connected inside the mounting frame 5, the drive end of the first motor 7 penetrating through the bottom wall of the mounting frame 5 and fixedly connected to a drill rod 8, an insertion rod 9 fixedly connected to the upper end face of the mounting frame 5, and a test cone 10 fixedly connected to the top end of the insertion rod 9; the drill rod 8 is driven to rotate by the first motor 7, and the drill rod 8 is lowered in conjunction with the lifting mechanism 4 to automatically drill a detection hole. The test cone 10 is prior art and will not be described in detail here.

[0031] like Figure 1 and Figure 5As shown, in a preferred embodiment, based on the above method, the ground insertion mechanism 2 further includes two symmetrical supports 201 fixed to the upper surface of the frame 1. Each support 201 contains a rotatable threaded bidirectional screw 202. Two movable blocks 203 are symmetrically threaded onto the bidirectional screw 202. A rotating rod 204 is rotatably connected to the bottom end of each movable block 203. A connecting block 205 is rotatably connected to the bottom end of each rotating rod 204. A lifting plate 20 is fixedly connected to the bottom ends of two adjacent connecting blocks 205. 6. The lifting plate 206 is slidably connected to the bracket 201. A set of grounding posts 207 are evenly fixedly connected to the lower end face of the lifting plate 206. The top of the grounding post 207 passes through the frame 1 and extends downward. When the bidirectional screw 202 rotates, the two moving blocks 203 will move closer or further away from each other. The movement of the moving blocks 203 drives the lifting plate 206 to slide up and down in the bracket 201 through the rotating rod 204 and the connecting block 205. When the lifting plate 206 descends, the grounding post 207 is inserted into the ground to fix the frame 1.

[0032] like Figure 1 and Figure 5 As shown, in a preferred embodiment, based on the above method, the ends of the bidirectional screw 202 are further provided with driven bevel gears 208 that penetrate the side wall of the bracket 201. Support plates 209 are fixedly connected to the rear ends of the two brackets 201. A drive shaft 2010 is rotatably connected between the support plates 209. Two driving bevel gears 2011 that mesh with the driven bevel gears 208 are fixedly connected to the drive shaft 2010. A crank handle 2012 is fixedly connected to one end of the drive shaft 2010. Rotating the crank handle 2012 drives the drive shaft 2010 and the driving bevel gears 2011 to rotate, which in turn drives the bidirectional screw 202 to rotate through the driven bevel gears 208.

[0033] like Figure 1 and Figure 3 As shown, in a preferred embodiment, based on the above method, the lifting mechanism 4 further includes a vertical frame 401 fixed at the center of the upper end face of the frame 1. A threaded rod 402 is rotatably connected inside the vertical frame 401. A second motor 403 is fixedly connected to the upper end face of the vertical frame 401. The driving end of the second motor 403 passes through the top wall of the vertical frame 401 and is fixedly connected to the top end of the threaded rod 402. A lifting block 404 is threadedly connected to the threaded rod 402. The outer end of the lifting block 404 is fixedly connected to the mounting plate 3. A guide rod 405 is slidably connected inside the lifting block 404. The upper and lower ends of the guide rod 405 are fixedly connected to the upper and lower ends of the vertical frame 401, respectively. The second motor 403 drives the threaded rod 402 to rotate, causing the lifting block 404 to rise and fall, thereby facilitating the adjustment of the height of the drill rod 8 or the test cone 10.

[0034] like Figure 1 , Figure 3 and Figure 4As shown, in a preferred embodiment, based on the above method, the reversing mechanism 6 further includes a bearing 601 fixed at the center of the outer wall of the mounting plate 3. A connecting shaft 602 is fixedly connected to the inner wall of the inner ring of the bearing 601. The outer end of the connecting shaft 602 is fixedly connected to the mounting frame 5. A worm gear 603 is fixedly connected to the connecting shaft 602. An assembly plate 604 is fixedly connected to the outer wall of the mounting plate 3. A third motor 605 is fixedly connected to the assembly plate 604. The driving end of the third motor 605 passes through the assembly plate 604 and is fixedly connected to a worm 606 that meshes with the worm gear 603. The third motor 605 drives the worm 606 to rotate. The worm 606, through meshing with the worm gear 603, drives the connecting shaft 602 and the mounting frame 5 to rotate, causing the mounting frame 5 to rotate 180 degrees, thereby realizing the reversal of the positions of the drill rod 8 and the test cone 10.

[0035] like Figure 1 and Figure 2 As shown, in a preferred embodiment, based on the above method, a universal wheel 11 is fixedly connected to each of the four corners of the lower end face of the frame 1, and a handrail 12 is fixedly connected to the upper end face of the rear end of the frame 1; the universal wheel 11 and the handrail 12 facilitate the movement of the frame 1, thereby facilitating the movement of the detection device and increasing flexibility.

[0036] Specifically, when using the detection device for soil pollution prevention and control: First, the frame 1 is moved to the position to be tested using the casters 11 and the handle 12. Then, the crank 2012 is turned, which drives the drive shaft 2010 and the driving bevel gear 2011 to rotate. This, in turn, drives the driven bevel gear 208 to rotate the double-acting screw 202. The double-acting screw 202 causes the two moving blocks 203 to move closer to each other. The lifting plate 206 is lowered through the rotating rod 204 and the connecting block 205, which causes the ground insertion post 207 to be inserted into the ground. Then, the first motor 7 is started to rotate the drill rod 8, and the second motor 403 is started to drive the threaded rod 4. 02 rotates, causing the lifting block 404 to descend, which in turn causes the drill rod 8 to descend and drill into the soil. After drilling to a suitable depth, the drill rod 8 rises, and the third motor 605 drives the worm gear 606 to rotate. The worm gear 606, through meshing with the worm wheel 603, drives the connecting shaft 602 and the mounting frame 5 to rotate, causing the mounting frame 5 to rotate 180 degrees, thereby reversing the positions of the drill rod 8 and the test cone 10. Then, the second motor 403 drives the threaded rod 402 to rotate, causing the lifting block 404 to descend, which in turn causes the mounting frame 5 to drive the insertion rod 9 and the test cone 10 to be inserted into the soil to detect soil pollution.

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
