Description

Technical Field

[0001] This invention relates to the field of geological disaster monitoring and prevention technology, specifically a geological disaster prevention and monitoring sampling device. Background Technology

[0002] Geological disasters, triggered by natural stress or human activities, can cause various types of geological damage, threatening people's lives and property and harming the ecological environment. The core of geological disaster prevention and control is to first assess the risk of unstable geological bodies, and then intervene in the disaster development process using professional geological engineering measures to avoid or reduce the harm caused by the disaster. The occurrence conditions, spatial distribution, and runoff transport patterns of groundwater are core elements influencing the evolution of geological disasters; therefore, routine groundwater monitoring is essential. Regularly collecting groundwater samples for analysis allows for accurate understanding of groundwater dynamics, providing a reliable basis for geological disaster risk prediction and hazard assessment.

[0003] For example, Chinese patent CN120177119A discloses a geological disaster prevention and monitoring sampling device, including a base. A mounting frame is fixedly connected to one side of the upper surface of the base, and a support frame is fixedly connected to one side of the right end of the mounting frame. A take-up reel is rotatably mounted at both ends of one side of the support frame. The sampling cup can pass through a through hole at the bottom of the housing. The housing is also equipped with an elastic radial pushing mechanism to prevent suspended matter on the water surface from adhering to the sampling cup. This invention utilizes an elastic radial pushing mechanism to drive multiple elastic cloths to move radially simultaneously, thus moving suspended matter away from the area where the sampling cup is about to descend. This avoids situations where clumps of foreign matter suspended on the water surface below the sampling cup adhere to the surface of the sampling cup when it enters the water, blocking the inlet hole and preventing water from entering the sampling cup normally, thus ensuring the smooth progress of the sampling work.

[0004] Through in-depth research, the inventors of this application discovered that the aforementioned patent's supporting pushing mechanism is complex and has a high failure rate. Furthermore, while the patent uses a pushing mechanism to remove floating debris from the water surface, this only addresses the problem of surface suspended clumps interfering with sampling. In actual operational scenarios, in addition to floating debris on the surface, various types of debris and impurities are distributed underwater. When the sampling cup sinks into the water to collect samples, underwater impurities easily clog the cup's inlet channel. Once a blockage occurs, the operator must pull the entire sampling device out of the water and clean the cup before sampling can resume, significantly reducing the overall efficiency of groundwater sampling. Summary of the Invention

[0005] This invention provides a geological disaster prevention and monitoring sampling device, which aims to solve the shortcomings of existing technologies, such as complex pushing mechanism structure, high failure rate, and inability to avoid underwater impurities interfering with sampling. This device has a simple and reliable structure, and can effectively block underwater impurities, ensuring the smooth progress of sampling operations.

The system includes: a moving component, wherein the pushing unit is used to push away floating debris on the water surface; a lifting box, which is connected to one end of a traction rope via a driving component, the lifting box including an operating box, a water inlet channel communicating with the operating box, and a screen plate installed at the other end of the water inlet channel, wherein an electronic valve is installed inside the water inlet channel; an underwater anti-clogging unit, which is installed inside the water inlet channel and is used to clean impurities attached to the outer wall of the screen plate in real time; and a conversion unit, which is installed inside the operating box and, in cooperation with a telescopic tube, enables multiple continuous water sample collection operations.

[0007] Preferably, the take-up unit includes two sets of upright plates fixedly connected to the top of the cabinet. A rotating rod is rotatably connected between the two sets of upright plates via bearings. A take-up roller is fixedly sleeved on the outer side of the rotating rod. A drive motor is provided on the outer side of one set of upright plates. The output end of the drive motor is fixedly connected to one end of the rotating rod. A traction rope is wound around the outer circumference of the take-up roller.

[0008] Preferably, the transmission assembly includes multiple sets of uprights fixedly connected inside the cabinet. Each upright has a gear rotatably connected inside. Each gear has a follower rod fixedly connected to both sides of its side surface. Each follower rod has a transmission rod rotatably connected to its outer side. The end of the transmission rod away from the follower rod is rotatably connected to a push plate via a pin. The push plate is rotatably connected to the bottom of the cabinet via a hinge.

[0009] Preferably, the drive assembly includes a connecting plate fixedly connected to one end of the traction rope, and multiple sets of racks are fixedly connected to the bottom of the connecting plate. Each set of racks is meshed with a corresponding gear, and the bottom of each rack is fixedly connected to the top of the lifting box.

[0010] Preferably, the underwater anti-clogging unit includes an impeller rotatably connected inside the water inlet channel. The impeller is fixedly sleeved on the outside of the transmission rod two. The transmission rod two extends to the outside of the water inlet channel and is rotatably connected to the water inlet channel. A fixing plate is fixedly connected to the end of the transmission rod two away from the water inlet channel.

[0011] Preferably, a pull plate is rotatably connected to the outer side of the fixed strip, and a sliding plate is rotatably connected to the end of the pull plate away from the fixed strip. Sliding grooves for the sliding plate to slide are provided on both sides of the water inlet channel, and a striking element is fixedly connected to the outer side of the end of the sliding plate close to the screen plate.

[0012] Preferably, the conversion unit includes a lead screw rotatably connected inside the control box, a brushless motor fixedly installed on the outside of the control box, the output end of the brushless motor fixedly connected to one end of the lead screw, a guide rod fixedly connected inside the control box, a telescopic pipe communicating with the water inlet channel at the junction with the control box, and mating blocks fixedly connected to both sides of the telescopic pipe extending to one end of the control box, one mating block being threadedly connected to the lead screw on one side, and the other mating block being slidably connected to the guide rod on the other side.

[0013] Preferably, the operation box has several sets of sampling bottles installed inside, the inner wall of the operation box has slots that fit the sampling bottles, and the operation box has a door on the front side.

[0014] Preferably, the bottom of the cabinet is provided with several sets of air cushions, and the periphery of the cabinet is provided with an air pump for use with the air cushions.

[0015] Preferably, a control panel is provided on the outer side of the handrail.

[0016] By adopting the above technical solution, the operator uses the handrails and casters on the outside of the cabinet to transport the device to the designated sampling point. The air pump around the cabinet is then activated to inflate the air cushion at the bottom of the cabinet. The expanded air cushion increases the grounding area of ​​the equipment, counteracts the displacement caused by operational vibrations and water disturbances, and also allows the device to be placed on the water surface for operation due to buoyancy. Next, the operator issues an operation command through the control panel, activating the drive motor to rotate the rotating rod and take-up roller between the two sets of vertical plates in the forward direction. The take-up roller releases the traction rope wound around the outer periphery, and the traction rope pulls the lifting box downwards at a uniform speed. The connecting plate and rack at the top of the lifting box descend synchronously. The rack drives the gear to rotate, causing the follower rod and transmission rod to move sequentially. This causes the push plate at the bottom of the cabinet to rotate downwards and unfold, pushing floating debris away from the sampling area. When the lifting box sinks to the preset water depth, the electronic valve in the water inlet channel opens, and the water flows through the screen plate at the end of the water inlet channel into the interior of the water inlet channel and impacts the impeller. The impeller drives the transmission rod, the fixed strip plate, and the pull plate. The combined motion drives the sliding plate to slide back and forth along the grooves on both sides of the water inlet channel. The striking parts on the sliding plate continuously strike the outer wall of the screen plate, thereby shaking off attached impurities in real time to prevent the screen plate from clogging. The water sample continuously flows through the water inlet channel and the telescopic tube into the sampling bottle in the operating box. After the sampling of a single bottle is completed, the electronic valve closes. Then, the brushless motor starts and drives the lead screw to rotate. The lead screw, together with the guide rod, drives two sets of mating blocks to move, causing the telescopic tube to move horizontally to align with the next sampling bottle. Then, the electronic valve reopens to continue sampling, and so on, to complete the water sample collection of all sampling bottles. After all the sampling work is completed, the drive motor runs in reverse, the take-up roller winds up the traction rope, and lifts the lifting box upward to reset. The rack moves upward and drives the gear to rotate in reverse. Each transmission component resets in sequence, the push plate rotates back to the closed state, and finally, the cabinet door on the front side of the cabinet and the box door of the operating box are opened in sequence to take out the collected sampling bottle and release the gas in the air cushion. Then, the moving wheels and the handrail transfer device can be used to complete the entire geological disaster prevention and monitoring sampling operation.

[0017] This invention provides a geological disaster prevention and monitoring sampling device. It has the following beneficial effects: 1. By setting up a pushing unit, the present invention can drive the push plate to unfold during the lowering of the lifting box, thereby actively pushing away floating debris on the water surface and avoiding interference with sampling. The push plate adopts a combination structure of hard material in the upper section and elastic rubber in the lower section, which has excellent sealing performance when closed and can effectively prevent debris from seeping into the sampling area from the gaps, further ensuring the cleanliness of the sampling environment.

[0018] 2. This invention, by setting up an underwater anti-clogging unit, relies on the power of water flow to drive the impeller to rotate, which drives the striking parts to continuously strike the screen plate, shaking off the attached underwater impurities in real time, preventing the screen plate from clogging at the source, eliminating the need for frequent manual cleaning of the equipment, and greatly improving the efficiency of operation; at the same time, the conversion unit is used in conjunction with electronic valves and telescopic tubes to automatically switch sampling bottles, realize the continuous collection of multiple sets of water samples, and achieve a high degree of automation.

[0021] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see the appendix Figure 1 -Appendix Figure 8 This invention provides a geological disaster prevention and control monitoring sampling device, including a cabinet 1, a cabinet door 101 hinged to the front of the cabinet 1, a handrail 102 integrally welded to the outside of the cabinet 1, and four casters 103 at the bottom corners of the cabinet 1; a cable reel 2, located on the top of the cabinet 1, with a slot on the outside of the cabinet 1 for a traction rope 205 to pass through, the cable reel 2 being used to pull and drive a lifting box 4 to rise and fall; a pushing unit 3, including a transmission component 301 inside the cabinet 1 and a drive component 302 fixedly connected to the top of the lifting box 4, the pushing unit 3 being used to push away floating debris on the surface of the water; and a lifting box 4, connected to one end of the traction rope 205 via the drive component 302. The lifting box 4 includes an operation box 401, a water inlet channel 402 connected to the operation box 401, and a screen plate 403 set at the other end of the water inlet channel 402. An electronic valve is installed inside the water inlet channel 402. An underwater anti-blocking unit 5 is set inside the water inlet channel 402 and is used to clean impurities attached to the outer wall of the screen plate 403 in real time. A conversion unit 6 is set inside the operation box 401 and, in cooperation with the telescopic tube 7, enables multiple continuous water sample collection operations. Several sets of sampling bottles 8 are installed inside the operation box 401. The inner wall of the operation box 401 has a slot adapted to the sampling bottles 8. A door is opened on the front side of the operation box 401, and a control panel 11 is set on the outside of the handrail 102.

[0023] Specifically, the operator uses the four corner casters 103 at the bottom of cabinet 1, along with the handrails 102 on the outside of cabinet 1, to push the entire device to the sampling point. Then, the operator issues a work command via the control panel 11 on the outside of the handrails 102. The cable reel 2 at the top of cabinet 1 operates and releases the traction rope 205. The traction rope 205 pulls the lifting box 4 downwards. The drive assembly 302 at the top of the lifting box 4 descends synchronously, cooperating with the transmission assembly 301 inside cabinet 1 to unfold the closed push plate 3015 outwards, pushing floating debris from the water surface below cabinet 1 away from the sampling area. When the lifting box 4 sinks to the preset water depth, the electronic valve inside the water inlet channel 402 opens, and the water passes through the sieve. The screen plate 403 flows into the water inlet channel 402. The water flow drives the underwater anti-blocking unit 5 in the water inlet channel 402 to operate. The striking part 507 continuously strikes the outer wall of the screen plate 403 to clean the attached impurities in real time and effectively prevent the channel from being blocked. At the same time, the conversion unit 6 inside the operation box 401 drives the telescopic tube 7 to align with different sampling bottles 8 in the box in turn to complete the continuous collection of multiple sets of water samples. After the sampling operation is completed, the take-up unit 2 rotates the traction rope 205 in the opposite direction, and the lifting box 4 and the drive component 302 rise synchronously. The push plate 3015 closes and resets. Finally, the cabinet door 101 of the cabinet body 1 and the box door of the operation box 401 are opened in turn to take out the sampling bottle 8 that has been collected. The entire sampling operation is then completed.

[0024] Please see the appendix Figure 2 -Appendix Figure 3 The take-up unit 2 includes two sets of upright plates 201 fixedly connected to the top of the cabinet 1. A rotating rod 202 is rotatably connected between the two sets of upright plates 201 through a bearing. A take-up roller 203 is fixedly sleeved on the outside of the rotating rod 202. A drive motor 204 is provided on the outside of one set of upright plates 201. The output end of the drive motor 204 is fixedly connected to one end of the rotating rod 202. A traction rope 205 is wound around the outer periphery of the take-up roller 203.

[0025] Specifically, after the staff issues a work command through the control panel 11, the drive motor 204 installed on the outside of a set of upright plates 201 in the take-up unit 2 starts. The output end of the drive motor 204 drives the rotating rod 202 between the two sets of upright plates 201 to rotate. The rotating rod 202 drives the take-up roller 203 fixedly sleeved on the outside to rotate in the forward direction. The take-up roller 203 gradually releases the traction rope 205 wrapped around its outer periphery. The traction rope 205 passes through the slot opened on the side wall of the cabinet 1 and pulls the lifting box 4 down at a uniform speed. When the lifting box 4 reaches the preset sampling depth, the drive motor 204 stops running. After the water sample is collected, the drive motor 204 is controlled to run in reverse to lift the lifting box 4 up to the initial position.

[0026] Please see the appendix Figure 4 -Appendix Figure 6The transmission assembly 301 includes multiple sets of uprights 3011 fixedly connected inside the cabinet 1. Gears 3012 are rotatably connected inside each upright 3011. Follower rods 3013 are fixedly connected to both sides of each gear 3012. Transmission rods 3014 are rotatably connected to the outer side of each follower rod 3013. A push plate 3015 is rotatably connected to the end of the transmission rod 3014 away from the follower rod 3013 via a pin. The push plate 3015 is rotatably connected to the bottom of the cabinet 1 via a hinge. The drive assembly 302 includes a connecting plate 3021 fixedly connected to one end of a traction rope 205. Multiple sets of racks 3022 are fixedly connected to the bottom of the connecting plate 3021. Each set of racks 3022 meshes with a corresponding gear 3012. The bottom of each rack 3022 is fixedly connected to the top of the lifting box 4.

[0027] Specifically, when the take-up unit 2 releases the traction rope 205 to move the lifting box 4 downward, the connecting plate 3021 and multiple sets of racks 3022 connected to the traction rope 205 descend accordingly. Each set of racks 3022 drives the gear 3012 on the corresponding upright 3011 to rotate. The follower rods 3013 fixed on both sides of the gear 3012 rotate with the gear 3012. The follower rods 3013 push the transmission rod 3014 connected to the outer side to swing. The push plate 3015 connected to the end of the transmission rod 3014 through the pin rotates downward around the hinge at the bottom of the cabinet 1, thereby moving the surface of the water. Floating debris is pushed away from the sampling area. After sampling is completed, the traction rope 205 lifts the lifting box 4 upward. The rack 3022 moves upward in sync and drives the gear 3012 to rotate in the opposite direction, causing the follower rod 3013 and the transmission rod 3014 to reset. The push plate 3015 is kept closed again. The push plate 3015 is divided into upper and lower parts. The upper part that connects with the transmission rod 3014 is made of hard material, and the lower part is made of elastic rubber material. This structural design effectively improves the sealing effect of the push plate 3015 in the closed state, preventing surface debris from seeping into the sampling area through gaps.

[0028] Please see the appendix Figure 7 The underwater anti-clogging unit 5 includes an impeller 501 rotatably connected inside the water inlet channel 402. The impeller 501 is fixedly sleeved on the outside of the transmission rod 502. The transmission rod 502 extends to the outside of the water inlet channel 402 and is rotatably connected to the water inlet channel 402. A fixing plate 503 is fixedly connected to the end of the transmission rod 502 away from the water inlet channel 402. A pull plate 504 is rotatably connected to the outside of the fixing plate 503. A sliding plate 505 is rotatably connected to the end of the pull plate 504 away from the fixing plate 503. Sliding grooves 506 are provided on both sides of the water inlet channel 402 for the sliding plate 505 to slide. A striking element 507 is fixedly connected to the outside of the end of the sliding plate 505 near the screen plate 403.

[0029] Specifically, when the lifting box 4 sinks to the preset water depth and the electronic valve in the water inlet channel 402 is opened, the water flows through the screen plate 403 into the water inlet channel 402 and impacts the impeller 501, causing the impeller 501 to rotate continuously. The impeller 501 drives the transmission rod 2 502 fixed on the outside to rotate synchronously. One end of the transmission rod 2 502 extends out of the water inlet channel 402 and drives the fixed strip plate 503 to swing back and forth. Then, the fixed strip plate 503 pulls the hinged pull plate 504, which in turn pushes the sliding plate 505 to move back and forth in a straight line along the sliding grooves 506 on both sides of the water inlet channel 402. The striking part 507 at the end of the sliding plate 505 continuously strikes the outer wall of the screen plate 403, shaking off the attached impurities in time, effectively preventing the screen plate 403 from clogging, ensuring smooth water intake, and improving the overall sampling efficiency.

[0030] Please see the appendix Figure 8 The conversion unit 6 includes a lead screw 601 rotatably connected inside the control box 401. A brushless motor 602 is fixedly installed on the outside of the control box 401. The output end of the brushless motor 602 is fixedly connected to one end of the lead screw 601. A guide rod 603 is also fixedly connected inside the control box 401. A telescopic tube 7 is connected at the intersection of the water inlet channel 402 and the control box 401. Both sides of the telescopic tube 7 extending to one end of the control box 401 are fixedly connected to mating blocks 604. One mating block 604 is threadedly connected to the lead screw 601, and the other mating block 604 is slidably connected to the guide rod 603.

[0031] Specifically, after the electronic valve in the water inlet channel 402 is opened, the water sample flows sequentially through the screen plate 403, the water inlet channel 402, and the telescopic tube 7 into the corresponding sampling bottle 8. After sampling of a single bottle is completed, the electronic valve is temporarily closed. Then, the brushless motor 602 on the outside of the control box 401 is started, and its output end drives the lead screw 601 to rotate. The lead screw 601 drives the displacement of one side of the mating block 604, and the other side of the mating block 604 slides smoothly along the guide rod 603. The two sets of mating blocks 604 synchronously drive the telescopic tube 7 to move as a whole, aligning the water outlet with the next empty sampling bottle 8. After that, the electronic valve is opened again to carry out the sampling operation, which greatly improves the efficiency of continuous sampling.

[0032] Please see the appendix Figure 2 The bottom of the cabinet 1 is equipped with several sets of air cushions 9, and the perimeter of the cabinet 1 is equipped with air pumps 10 that work in conjunction with the air cushions 9.

[0033] Specifically, the air pump 10 is started, and the air pump 10 inflates the air cushion 9 at the bottom of the cabinet 1. The air cushion 9 gradually expands and lifts the entire cabinet 1, which increases the contact area between the equipment and the ground, effectively offsetting the displacement problems caused by equipment vibration and water disturbance. In addition, the inflated air cushion 9 also has a buoyancy effect, which can support the entire device to be placed directly in the water environment for operation, adapting to more sampling scenarios.

[0034] Workflow: The operator uses the handrail 102 and casters 103 on the outside of the cabinet 1 to move the device to the designated sampling point. The operator then starts the air pump 10 around the cabinet 1 to inflate the air cushion 9 at the bottom of the cabinet 1. The inflated air cushion 9 increases the ground contact area of ​​the equipment, counteracts displacement caused by operational vibrations and water disturbances, and also allows the device to be placed on the water surface for operation due to buoyancy. Next, the operator issues a work command through the control panel 11, activating the drive motor 204, which drives the rotating rod 202 and take-up roller 203 between the two sets of upright plates 201 to rotate forward. The take-up roller 203 releases the traction rope 205 wound around its outer periphery, and the traction rope 205 pulls the device upwards. The lifting box 4 moves downward at a constant speed. The connecting plate 3021 and rack 3022 at the top of the lifting box 4 descend synchronously. The rack 3022 drives the gear 3012 to rotate, causing the follower rod 3013 and transmission rod 3014 to move in sequence. As a result, the push plate 3015 at the bottom of the cabinet 1 rotates downward and unfolds, pushing floating debris on the water surface away from the sampling area. When the lifting box 4 sinks to the preset water depth, the electronic valve in the water inlet channel 402 opens. The water flows through the screen plate 403 at the end of the water inlet channel 402 and enters the interior of the water inlet channel 402, impacting the impeller 501. The impeller 501 drives the transmission rod 502, the fixed strip 503, and the pull plate 501. 04. The sliding plate 505 is driven to slide back and forth along the grooves 506 on both sides of the water inlet channel 402 in coordination with the movement. The striking parts 507 on the sliding plate 505 continuously strike the outer wall of the screen plate 403, thereby shaking off attached impurities in real time to prevent the screen plate 403 from clogging. The water sample continuously flows through the water inlet channel 402 and the telescopic tube 7 into the sampling bottle 8 in the operation box 401. After sampling of a single bottle is completed, the electronic valve closes. Then, the brushless motor 602 starts and drives the lead screw 601 to rotate. The lead screw 601, in conjunction with the guide rod 603, drives the two sets of mating blocks 604 to move, causing the telescopic tube 7 to move horizontally to align with the next sampling bottle 8. Subsequently, the electronic valve reopens. Continue sampling, and repeat the process to collect water samples from all sampling bottles 8. After all sampling is completed, the drive motor 204 reverses, the take-up roller 203 winds up the traction rope 205, and the lifting box 4 is lifted and reset. The rack 3022 moves upward and drives the gear 3012 to rotate in the opposite direction. Each transmission component is reset in sequence, and the push plate 3015 rotates back to the closed state. Finally, the cabinet door 101 on the front side of the cabinet 1 and the box door of the operation box 401 are opened in sequence to take out the collected sampling bottles 8 and release the gas in the air cushion 9. Then, the entire geological disaster prevention and monitoring sampling operation can be completed by using the moving wheels 103 and the handrail 102 to transfer the device.
