Description

Technical Field

[0001] The present invention belongs to the technical field of geological disaster prevention and control monitoring, and specifically relates to a sampling device for geological disaster prevention and control monitoring. Background Art

[0002] Geological disasters refer to geological phenomena formed under the action of natural or human factors that cause damage and losses to human life, property, and the environment. Geological disaster prevention and control is to evaluate adverse geological phenomena and, through effective geological engineering technical means, change the process of these geological disasters to prevent or mitigate the occurrence of disasters. Among them, the state, distribution, and flow characteristics of groundwater directly affect the occurrence and development of geological disasters. Therefore, regular monitoring of groundwater quality is particularly crucial. By sampling and analyzing groundwater, the state and characteristics of groundwater can be understood, thereby predicting and evaluating the risk of geological disasters.

[0003] The patent with the publication number CN215811797U discloses a sampling device for geological disaster prevention and control monitoring, including a trolley. On the upper right side of the top of the trolley, there is a vertical frame. On the upper part of the right side of the vertical frame, a wire reel is rotatably arranged. The left end of the wire reel is connected to a driving motor. A lifting rope is wound around the wire reel. The lifting end of the lifting rope is tied to a sampler. Between the left side of the vertical frame and the bottom plate of the trolley, there is a reinforcing rib plate. This patent remotely controls the telescopic cylinder to start through a wireless transmission module, so that the water inlet hole can be remotely opened or closed. Then, the sampler is lifted by the lifting rope. The whole groundwater sampling process is simple and fast to operate, and the structural design is simple and reasonable, which is convenient for actual use. In this patent, the sampling structure is designed on the trolley, which can be conveniently and labor-savingly moved to the sampling position, and a flow velocity sensor is designed, which can detect the underground water flow velocity to obtain more sufficient disaster information.

[0004] However, the above technical solution still has the following deficiencies in the actual application process: By inserting the sampling cup into the groundwater, the groundwater enters the sampling cup through the water inlet hole for sampling. Since groundwater is often related to surface water to a certain extent, when surface water flows into the groundwater, it may carry some foreign matters such as plant roots and animal hairs, and these foreign matters may suspend on the water surface and form lumps. When there are lump foreign matters suspended on the water surface below the sampling cup, when the sampling cup enters the water, foreign matters may adhere to the surface of the sampling cup and cover the water inlet hole, resulting in the groundwater being unable to smoothly enter the inside of the sampling cup and affecting the normal sampling work. In order to avoid this situation and change the descending position of the sampling cup, it will also deviate from the original sampling location, affecting the accuracy of subsequent analysis results.

[0005] Therefore, the present invention provides a sampling device for geological disaster prevention and control monitoring. Summary of the Invention

[0010] Preferably, a plurality of partition plates are fixedly connected to the inner cavity wall of the sampling cup. A plurality of water inlet pipes are arranged on the sampling cup. A solenoid valve is arranged on one side of the water inlet pipe. The partition plates divide the inside of the sampling cup into a plurality of storage cavities.

[0011] Preferably, a plurality of connecting rods one are rotatably arranged on the upper end surface of the installation ring. One end of the connecting rod one is rotatably connected with a connecting rod two. One end of the connecting rod two is rotatably connected with one end of the adjusting rod.

[0012] Preferably, a gear ring is sleeved and rotatably connected to the outer ring of the installation ring. Tooth blocks are intermittently arranged on the inner ring of the gear ring. A gear is fixedly connected to one end of the connecting rod one. The gear meshes with the tooth blocks on the inner ring of the gear ring. A motor four is fixedly connected to one side of the installation ring. The output end of the motor four is fixedly connected to one end of the connecting rod one.

[0013] Preferably, one side of the upper end face of the inner cavity of the housing is fixedly connected with a limiting rod, the limiting rod is slidably connected with a connecting ring, the lower end face of the connecting ring is fixedly connected with a connecting rod, the lower end of the connecting rod is fixedly connected with a chute plate, both sides of the chute plate are slidably connected with clamping rods, one side of the clamping rod is fixedly connected with an elastic strip, and a plurality of rectangular grooves through which the clamping rods can pass are arranged at the bottom of the housing.

[0014] Preferably, one side of the connecting ring is threadedly connected with a threaded rod, the upper end of the threaded rod is rotatably arranged on the housing, and one side of the upper end face of the housing is fixedly connected with a second motor, and the output end of the second motor is fixedly connected with the upper end of the threaded rod.

[0016] Preferably, one side of the upper end face of the base is fixedly connected with a handle, and a plurality of universal wheels are arranged on the lower end face of the base.

[0017] The beneficial effects of the present invention are as follows: 1. For the geological disaster prevention and control monitoring and sampling device of the present invention, when the sampling cup descends to an appropriate depth, the electromagnetic valve on the water inlet pipe can be opened to allow groundwater to flow into the sampling cup through the water inlet pipe. Moreover, since the partition divides the inner cavity of the sampling cup into multiple storage cavities, different depths of groundwater can be made to flow into different storage cavities respectively by sequentially opening the electromagnetic valves at different positions. After the sampling is completed, the sampling cup is removed from the groundwater, and groundwater samples at different depths can be obtained, which is beneficial to improving the accuracy of subsequent analysis results.

[0018] 2. For a geological disaster prevention and control monitoring sampling device described in the present invention, by using an elastic radial pushing mechanism and driving multiple elastic cloths to move radially simultaneously, the suspended matter is moved away from the area where the sampling cup is about to descend, thus avoiding the situation that when the sampling cup enters the water, foreign matter agglomerates are suspended on the water surface below the sampling cup, and foreign matter adheres to the surface of the sampling cup, covering the water inlet hole and preventing water from flowing into the sampling cup normally, ensuring the smooth progress of the sampling work. At the same time, it also avoids the situation that the sampling cup deviates from the original sampling location due to adjusting the position of the sampling cup, affecting the subsequent analysis results. Moreover, during the entire sampling process, the elastic cloth can intercept the suspended matter, and the suspended matter will not move into the enclosure formed by multiple elastic cloths, thus avoiding the situation that when the sampling cup rises, the suspended matter adheres to the surface of the sampling cup, affecting the subsequent sampling effect of the sampling cup. And when the sampling cup completes sampling and returns from the water to the housing, the clamping rod can be driven to pass through the rectangular groove, so that the two clamping rods slide and approach each other simultaneously until the elastic strip is in close contact with the surface of the elastic cloth, and then the clamping rod is continuously driven to descend. During the descent of the clamping rod, the elastic strip can scrape off the suspended matter attached to the surface of the elastic cloth, thus realizing the removal of the suspended matter on the surface of the elastic cloth and avoiding the situation that in the subsequent sampling process, the elastic cloth always carries these suspended matters, affecting the elasticity of the elastic cloth and the interception effect on the suspended matter.

[0019] 3. For a geological disaster prevention and control monitoring sampling device described in the present invention, the staff holds the handle, and the whole device can be moved by using the universal wheels, which is relatively convenient. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0023] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work belong to the scope of protection of the present invention.

[0024] Please refer to Figures 1-9 , the present invention provides a technical solution: a geological disaster prevention and control monitoring sampling device, including a base 1, one side of the upper end face of the base 1 is fixedly connected with a mounting bracket 2, one side of the right end face of the mounting bracket 2 is fixedly connected with a support frame 5, both ends of one side of the support frame 5 are rotatably provided with a wire reel 1 7, a lifting rope 1 8 is wound on the wire reel 1 7, the end of the lifting rope 1 8 is provided with a connecting block 17, and a housing 9 is installed on the connecting block 17 through a plurality of lifting ropes 3 16. One side of the inner cavity of the housing 9 is rotatably provided with a wire reel 2 21, a lifting rope 2 15 is wound on the wire reel 2 21, the end of the lifting rope 2 15 is provided with a sampling cup 10, and the sampling cup 10 can pass through the through hole at the bottom of the housing 9. An elastic radial pushing mechanism for preventing suspended matter on the water surface from adhering to the sampling cup 10 is also provided on the housing 9; The elastic radial pushing mechanism includes a mounting ring 12 fixedly connected to one side of the outer wall of the housing 9. A plurality of adjusting rods 27 are distributed along the radial direction and slidably connected to the mounting ring 12. The end of the adjusting rod 27 is fixedly connected with a displacement column 28, and an elastic cloth 29 is fixedly connected between adjacent displacement columns 28.

[0025] In this embodiment, as Figure 1 , Figure 3 , Figure 6 shown, one side of the support frame 5 is fixedly connected with a motor 1 6, and the output end of the motor 1 6 is fixedly connected to one end of the wire reel 1 7.

[0026] One side of the inner cavity of the housing 9 is fixedly connected with a motor 3 22, and the output end of the motor 3 22 is fixedly connected to one end of the wire reel 2 21.

[0027] A plurality of partition plates 20 are fixedly connected to the inner cavity wall of the sampling cup 10. A plurality of water inlet pipes 14 are arranged on the sampling cup 10. A solenoid valve 19 is arranged on one side of the water inlet pipe 14. The partition plates 20 divide the interior of the sampling cup 10 into a plurality of storage cavities.

[0028] Specifically, place the base 1 in a suitable position. First, use the first motor 6 to drive the first wire reel 7 to rotate, so as to unwind the first lifting rope 8, lower the housing 9 to the water surface. Then, use the third motor 22 to drive the second wire reel 21 to rotate, so as to unwind the second lifting rope 15, and make the sampling cup 10 extend into the groundwater. When the sampling cup 10 descends to a suitable depth, the solenoid valve 19 on the water inlet pipe 14 can be opened to make the groundwater flow into the sampling cup 10 through the water inlet pipe 14. And because the partition plates 20 divide the inner cavity of the sampling cup 10 into a plurality of storage cavities, so, by sequentially opening the solenoid valves 19 at different positions, the groundwater at different depths can flow into different storage cavities respectively. After the sampling is completed, then move the sampling cup 10 out of the groundwater, and groundwater samples at different depths can be obtained, which is beneficial to improving the accuracy of subsequent analysis results.

[0029] In this embodiment, as Figure 2 、 Figures 4-9 shown, a plurality of first connecting rods 31 are rotatably arranged on the upper end surface of the mounting ring 12. One end of the first connecting rod 31 is rotatably provided with a second connecting rod 32. One end of the second connecting rod 32 is rotatably connected to one end of the adjusting rod 27.

[0030] A gear ring 13 is sleeved and rotatably connected to the outer ring of the mounting ring 12. Tooth blocks are intermittently arranged on the inner ring of the gear ring 13. One end of the first connecting rod 31 is fixedly connected with a gear 33. The gear 33 meshes with the tooth blocks on the inner ring of the gear ring 13. One side of the mounting ring 12 is fixedly connected with a fourth motor 30. The output end of the fourth motor 30 is fixedly connected to one end of the first connecting rod 31.

[0031] One side of the upper end surface of the inner cavity of the housing 9 is fixedly connected with a limiting rod 23. A connecting ring 25 is slidably connected to the limiting rod 23. The lower end surface of the connecting ring 25 is fixedly connected with a connecting rod 26. The lower end of the connecting rod 26 is fixedly connected with a sliding groove plate 34. Clamping rods 36 are slidably connected to both sides of the sliding groove plate 34. One side of the clamping rod 36 is fixedly connected with an elastic strip 37. A plurality of rectangular grooves through which the clamping rods 36 can pass are arranged at the bottom of the housing 9.

[0032] One side of the connecting ring 25 is threadedly connected with a threaded rod 24. The upper end of the threaded rod 24 is rotatably arranged on the housing 9. One side of the upper end surface of the housing 9 is fixedly connected with a second motor 11. The output end of the second motor 11 is fixedly connected to the upper end of the threaded rod 24.

[0033] One side of the upper end of the clamping rod 36 is threadedly connected with a bidirectional threaded rod 18. Both ends of the bidirectional threaded rod 18 are rotatably arranged on the chute plate 34. One side of the chute plate 34 is fixedly connected with a fifth motor 35. The output end of the fifth motor 35 is fixedly connected with one end of the bidirectional threaded rod 18.

[0034] Specifically, when the existing geological disaster prevention and control monitoring sampling device is in use, the sampling cup 10 is inserted into the groundwater. The groundwater enters the sampling cup 10 through the water inlet hole for sampling. Since the groundwater is often related to the surface water to a certain extent, when the surface water flows into the groundwater, it may carry some foreign matters such as plant roots and animal hairs. And these foreign matters may suspend on the water surface and form lumps. When there are lump foreign matters suspended on the water surface below the sampling cup 10, when the sampling cup 10 enters the water, foreign matters may adhere to the surface of the sampling cup 10 and cover the water inlet hole, resulting in the groundwater being unable to enter the sampling cup 10 smoothly, affecting the normal sampling work. And when changing the descending position of the sampling cup 10 to avoid this situation, it will also deviate from the original sampling location, affecting the accuracy of the subsequent analysis results. Therefore, to solve the above problems, when this embodiment is in use, in the initial state, the sampling cup 10 is inside the inner cavity of the housing 9, and the distance between the plurality of displacement columns 28 is small. When the housing 9 descends until the end of the displacement column 28 contacts the water surface, the fourth motor 30 is used to drive the connecting rod one 31 on one side to rotate. Then, under the action of the gear 33, the toothed ring 13 can be rotated, so that the plurality of connecting rods one 31 and the connecting rods two 32 rotate simultaneously, and the plurality of adjusting rods 27 slide radially along the mounting ring 12 at the same time, so that the distance between the plurality of displacement columns 28 becomes larger. And when the displacement column 28 moves, the elastic cloth 29 also moves and is stretched, so that the volume of the cavity formed by the plurality of elastic cloths 29 gradually becomes larger. During this process, the suspended matters on the water surface below the sampling cup 10 will be pushed by the elastic cloth 29, so that the suspended matters move away from the area where the sampling cup 10 is about to descend. When the enclosure formed by the plurality of elastic cloths 29 is sufficient to accommodate the sampling cup 10, the second wire reel 21 can be driven to rotate, so that the sampling cup 10 enters the water for sampling. Thus, it is avoided that when there are lump foreign matters suspended on the water surface below the sampling cup 10 and the sampling cup 10 enters the water, foreign matters adhere to the surface of the sampling cup 10 and then cover the water inlet hole, resulting in the water flow being unable to enter the sampling cup 10 normally, ensuring the smooth progress of the sampling work. At the same time, it also avoids the situation that the sampling cup 10 deviates from the original sampling location due to adjusting the position of the sampling cup 10, affecting the subsequent analysis results. And during the whole sampling process, the elastic cloth 29 can intercept the suspended matters, and the suspended matters will not move into the enclosure formed by the plurality of elastic cloths 29. Furthermore, it is avoided that when the sampling cup 10 rises, the suspended matters adhere to the surface of the sampling cup 10, affecting the subsequent sampling effect of the sampling cup 10. Moreover, since the elastic cloth 29 intercepts the suspended matter on the water surface, the suspended matter is also likely to adhere to the surface of the elastic cloth 29. When there is a large amount of suspended matter accumulated on the surface of the elastic cloth 29, during the subsequent sampling process, the elastic cloth 29 will always carry this suspended matter, thus affecting the elasticity of the elastic cloth 29 and the interception effect on the suspended matter. Therefore, to avoid this situation, after the sampling cup 10 completes sampling and returns from the water into the housing 9, since the elastic cloth 29 is aligned with the rectangular groove at the bottom of the housing 9 at this time, the motor two 11 can be driven to rotate the threaded rod 24, causing the connecting ring 25 to descend, and the clamping rod 36 passes through the rectangular groove. After the elastic cloth 29 is between the two clamping rods 36, the motor five 35 can be used to drive the bidirectional threaded rod 18 to rotate, causing the two clamping rods 36 to slide and approach each other simultaneously until the elastic strip 37 is in close contact with the surface of the elastic cloth 29. Then, the clamping rod 36 is continuously driven to descend. During the descent of the clamping rod 36, the elastic strip 37 can scrape off the suspended matter attached to the surface of the elastic cloth 29. Moreover, since the elastic strip 37 has a certain elasticity, when the elastic strip 37 scrapes off the suspended matter on the surface of the elastic cloth 29, it will not cause damage to the elastic cloth 29, thus realizing the removal of the suspended matter on the surface of the elastic cloth 29 and avoiding the situation that during the subsequent sampling process, the elasticity of the elastic cloth 29 and the interception effect on the suspended matter are affected due to the elastic cloth 29 always carrying this suspended matter.

[0035] In this embodiment, as Figure 1 shown, one side of the upper end surface of the base 1 is fixedly connected with a handle 3, and a plurality of universal wheels 4 are arranged on the lower end surface of the base 1.

[0036] Specifically, the staff holds the handle 3, and the whole device can be moved by using the universal wheels 4, which is relatively convenient.

[0037] Working principle: The operator holds the handle 3, and the entire device can be moved by using the universal wheels 4. When the base 1 is placed in the appropriate position, first use the first motor 6 to drive the first wire reel 7 to rotate, and then the first lifting rope 8 can be unreeled, so that the housing 9 descends to the water surface. Then use the third motor 22 to drive the second wire reel 21 to rotate, and the second lifting rope 15 can be unreeled, so that the sampling cup 10 extends into the groundwater. When the sampling cup 10 descends to the appropriate depth, the solenoid valve 19 on the water inlet pipe 14 can be opened, so that the groundwater flows into the sampling cup 10 through the water inlet pipe 14. And because the partition plate 20 divides the inner cavity of the sampling cup 10 into multiple storage cavities, different depths of groundwater can flow into different storage cavities by sequentially opening the solenoid valves 19 at different positions. After the sampling is completed, the sampling cup 10 is removed from the groundwater, and groundwater samples at different depths can be obtained, which is conducive to improving the accuracy of subsequent analysis results. And when the housing 9 descends to the end of the displacement column 28 contacting the water surface, use the fourth motor 30 to drive the first connecting rod 31 on one side to rotate, and then the gear ring 13 can be rotated under the action of the gear 33, so that multiple first connecting rods 31 and second connecting rods 32 rotate simultaneously, and multiple adjusting rods 27 slide radially along the mounting ring 12 at the same time, so that the distance between multiple displacement columns 28 becomes larger. And when the displacement column 28 moves, the elastic cloth 29 also moves and is stretched, so that the volume of the cavity formed by multiple elastic cloths 29 gradually becomes larger. During this process, the suspended matter on the water surface below the sampling cup 10 will be pushed by the elastic cloth 29, so that the suspended matter moves away from the area where the sampling cup 10 is about to descend. When the enclosure formed by multiple elastic cloths 29 is large enough to accommodate the sampling cup 10, the second wire reel 21 can be driven to rotate, so that the sampling cup 10 enters the water for sampling, thus avoiding the situation that when there are lump foreign objects suspended on the water surface below the sampling cup 10 and the sampling cup 10 enters the water, foreign objects adhere to the surface of the sampling cup 10 and then cover the water inlet hole, resulting in the inability of water to normally enter the sampling cup 10, ensuring the smooth progress of the sampling work. At the same time, it also avoids the situation that the sampling cup 10 deviates from the original sampling location due to the adjustment of the position of the sampling cup 10, affecting the subsequent analysis results. And during the entire sampling process, the elastic cloth 29 can intercept the suspended matter, and the suspended matter will not move into the enclosure formed by multiple elastic cloths 29, thus avoiding the situation that when the sampling cup 10 rises, the suspended matter adheres to the surface of the sampling cup 10, affecting the subsequent sampling effect of the sampling cup 10;Furthermore, since the elastic cloth 29 has an intercepting effect on suspended matter on the water surface, the suspended matter is also easily attached to the surface of the elastic cloth 29. When a large amount of suspended matter accumulates on the surface of the elastic cloth 29, the elastic cloth 29 will always carry these suspended matter during the subsequent sampling process, thereby affecting the elasticity of the elastic cloth 29 and the intercepting effect of the suspended matter. Therefore, in order to avoid this situation, when the sampling cup 10 completes sampling and returns from the water to the shell 9, since the elastic cloth 29 is aligned with the rectangular groove at the bottom of the shell 9 at this time, the motor 21 can drive the threaded rod 24 to rotate, so that the connecting ring 25 descends, and the clamping rod 36 passes through the rectangular groove. When the elastic cloth 29 is between the two clamping rods 36, The motor 5 35 is used to drive the bidirectional threaded rod 18 to rotate, so that the two clamping rods 36 slide and approach each other at the same time, until the elastic strip 37 is closely attached to the surface of the elastic cloth 29, and then the clamping rod 36 is driven down. During the descent of the clamping rod 36, the elastic strip 37 can scrape off the suspended matter attached to the surface of the elastic cloth 29. Moreover, since the elastic strip 37 has a certain elasticity, the elastic strip 37 scrapes off the suspended matter on the surface of the elastic cloth 29 without damaging the elastic cloth 29, thereby achieving the removal of the suspended matter on the surface of the elastic cloth 29, and avoiding the elasticity of the elastic cloth 29 and the interception effect of the suspended matter being affected by the elastic cloth 29 always carrying these suspended matter in the subsequent sampling process. ;
