Description

Technical Field

[0001] This invention relates to the field of hydrodynamic control technology, specifically a hydrodynamic control device for groundwater pollution prevention and control. Background Technology

[0002] Groundwater pollution is a phenomenon caused by human factors that deteriorate groundwater quality. The main causes of groundwater pollution include: direct discharge of industrial wastewater into the ground, intrusion of polluted surface water into underground aquifers, and seepage of water contaminated by human or animal excrement or excessive pesticide use. The result of pollution is an increase in the levels of harmful components in groundwater, such as phenols, chromium, mercury, arsenic, radioactive substances, bacteria, and organic matter. Polluted groundwater is harmful to human health and industrial and agricultural production. Current technologies utilize hydrodynamic control to treat groundwater pollution.

[0003] Hydrodynamic control refers to the use of a well system to artificially alter the hydraulic gradient of groundwater by pumping or injecting water into the aquifer, thereby separating contaminated water bodies from clean water bodies. Depending on the arrangement of the well system, hydrodynamic control can be divided into upstream and downstream watersheds. An upstream watershed involves placing a row of injection wells upstream of the contaminated water body to inject clean water into the aquifer, creating an underground watershed at that well location and preventing clean water from upstream from replenishing the contaminated water body. Simultaneously, a row of pumping wells is placed downstream to extract and treat the contaminated water. A downstream watershed involves placing a row of injection wells downstream of the contaminated water body to create a watershed downstream, preventing the contamination plume from spreading downstream. Simultaneously, a row of pumping wells is placed upstream to extract clean water and inject it downstream. Similarly, hydrodynamic control is generally used as a temporary measure in the initial stages of groundwater pollution remediation to prevent the spread of pollutants.

[0004] While it is possible to prevent the pollution plume from spreading downstream by placing pumping wells downstream and injection wells upstream, this process requires the pumping wells to be submerged in groundwater. Prolonged immersion in water will accelerate the corrosion of the metal of the wells themselves, rendering them unusable. In addition, the groundwater may contain some solid pollutants, which can easily cause pipe blockage and corrosion as they enter the pipeline with the pumping wells. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a hydrodynamic control device for groundwater pollution prevention and control to solve the problems mentioned in the background. The present invention has a novel structure, with a row of pumps installed inside the installation box, which can move up and down together with the lifting assembly. When groundwater needs to be extracted, the installation box is lowered, and the pumps extract the polluted groundwater. At the same time, the cleaning assembly cleans the front of the filter plate to prevent pollutants from clogging the filter plate. When not in use, the installation box and pumps are raised to prevent the pumps from being corroded by long-term immersion in water.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hydrodynamic control device for groundwater pollution prevention and control, comprising a top frame, with vertical columns fixed to both sides at the front and rear ends, and the bottom of each column having a pointed tip; a front plate fixed to the front end of the top frame, and a filter plate fixed to the bottom of the front plate; a water quality monitoring sensor mounted on the surface of the filter plate; a mounting box at the bottom of the top frame, with a drain plate fixed to the bottom of the mounting box; multiple sets of water pumps fixedly mounted at equal intervals on the top of the drain plate; an inlet at the bottom of the front end of each water pump; and a main pipe connected to the top of the rear end of each water pump. The main pipe extends out from one side of the box, and the end of the main pipe is connected to a connecting box. A feed pipe is fixed to the bottom of the other end of the connecting box. A lifting assembly is provided on the top of the top frame. The lifting assembly includes a winding seat. Three sets of winding seats are fixed at equal intervals on the top of the top frame. A pull rope is wound on the winding shaft of the winding seat. The pull rope passes through the top frame and is fixedly connected to the top of the mounting box. A cleaning assembly is provided at the front end of the front plate and the filter plate. The cleaning assembly includes a mounting frame. Multiple water wheels are rotatably mounted at equal intervals on the surface of the mounting frame. The position of the water wheels corresponds to the water inlet. A sweeping plate is provided at the rear end of the water wheels. The sweeping plate slides in contact with the outer surface of the filter plate and the front plate.

[0007] Furthermore, sliders are fixed on both sides of the mounting box corresponding to the positions of the vertical columns, and the sliders are slidably sleeved on the vertical columns. Heat dissipation grooves are provided on the back and top of the mounting box.

[0008] Furthermore, the lifting assembly also includes a shaft, the top of the top frame is rotatably mounted on the shaft via a bearing, the winding shaft of the winding seat is fixedly connected to the shaft, a drive motor is fixedly mounted on the top frame at one end of the shaft, and the output end of the drive motor is fixedly connected to the shaft.

[0009] Furthermore, the cleaning assembly also includes a bearing seat, which is provided on one side of the water wheel and is rotatably sleeved on the mounting frame. Both ends of the mounting frame are fixedly connected to the slider. A connecting rod is rotatably installed on the bearing seat at the position corresponding to the sweeping plate, and the sweeping plate is fixedly connected to the connecting rod.

[0010] Furthermore, a first gear is fixed at the center of the waterwheel, and a second gear is meshed with the top of the first gear. A first bevel gear is fixed at the shaft of the second gear. A second bevel gear is fixed at one end of the connecting rod near the first bevel gear, and the first bevel gear and the second bevel gear are meshed together. The second gear and the first bevel gear are rotatably mounted on the shaft seat.

[0011] Furthermore, a fixing plate is fixed on one side of the connecting box, and the fixing plate is fixedly connected to the top frame. A plug plate is slidably inserted into one end of the connecting box corresponding to the main pipe, and the plug plate passes through the upper and lower ends of the connecting box. The main pipe is fixedly inserted through the plug plate. A first connecting ring is slidably sleeved on one end of the main pipe that enters the connecting box, and a second connecting ring is slidably sleeved on the surface of the delivery pipe.

[0012] Furthermore, a return spring is fixed at an equal distance from the rear end of the first connecting ring, and the other end of the return spring is fixedly connected to the outer wall of the main pipe. The first connecting ring and the second connecting ring are inserted into each other.

[0013] Furthermore, a bidirectional electric push rod is fixed to the bottom of the connecting box, and both extended ends of the bidirectional electric push rod are fixed with contact plates. One contact plate of the bidirectional electric push rod is fixedly connected to the second connecting ring.

[0014] Furthermore, a bottom frame is fixed to the back of the filter plate, and multiple right-angle plates are equidistantly mounted inside the bottom frame via a rotating shaft and a torsion spring, with the vertical surfaces of the right-angle plates in contact with the back of the filter plate.

[0015] Furthermore, a top rod is fixed to the top of the right-angle plate, and a ball is provided at the upper end of the top rod, with the ball of the top rod in sliding contact with the bottom of the drain plate.

[0016] The beneficial effects of this invention are:

[0017] 1. This invention uses a drive motor to rotate the shaft, and the winding shafts of the three winding seats rotate synchronously to wind up the pull rope. The installation box moves vertically, and the bottom leaves the water surface and enters the interior of the top frame. The bottom drain plate can drain the water on the water pump to avoid residual water stains. When the winding seat unwinds the pull rope, the installation box descends along the vertical column by its own weight until the bottom is inserted into the water surface. The water inlet of the water pump corresponds to and contacts the filter plate. The filter plate blocks solid pollutants in the underground sewage. The heat dissipation grooves on the back and top of the installation box can ensure the heat dissipation capacity of the water pump during operation.

[0018] 2. This invention uses a mounting frame and a slider for fixed connection, so the cleaning component moves together with the mounting box, leaving or inserting into the water surface together. This reduces corrosion of the gear structures within the cleaning component. When the mounting box descends, the water wheel inserts into the water surface. The natural flow velocity of the groundwater and the suction generated when the water pump draws groundwater provide the surrounding water flow with the force to drive the water wheel to rotate. As a result, the first gear rotates with the water wheel and meshes with the second gear. The first bevel gear rotates with the second gear and meshes with the second bevel gear. The connecting rod and the sweeping plate rotate with the second bevel gear. The sweeping plate performs a circumferential cleaning of the front of the filter plate, removing accumulated solid pollutants and preventing blockage of the water pump inlet.

[0019] 3. In this invention, the two extended ends of the bidirectional electric push rod retract, and the first connecting ring and the second connecting ring are inserted. A sealing ring can also be set at the insertion position to improve the sealing performance. Thus, the groundwater pumped by the water pump can be transported through the main pipe and then sent out through the delivery pipe. When the bidirectional electric push rod moves the two contact plates away, the first connecting ring slides backward under the action of the return spring, which facilitates the separation of the main pipe and the delivery pipe. The movement of the installation box will not be interfered with by the delivery pipe.

[0020] 4. When the mounting box is pulled upward by the lifting assembly, the right-angle plate gradually flips from a flat state to a vertical state under the elastic force of its own torsion spring, and the vertical surface of the right-angle plate contacts the back of the filter plate. This function is to reduce the probability of filter plate deformation caused by the water flow impact force after the mounting box is raised. When the mounting box is raised to the highest point, the top of the top rod contacts the drain plate. Then, when the mounting box is lowered, the drain plate will press the ball at the top of the top rod to restore the right-angle plate to a flat state, keeping it parallel to the bottom frame, and serving as the bottom support of the mounting box.

[0021] 5. Compared with the prior art, the present invention has a row of water pumps installed inside the installation box, which can move up and down with the lifting component. When it is necessary to extract groundwater, the installation box is lowered and the water pumps extract the groundwater. At the same time, the cleaning component cleans the front of the filter plate to prevent pollutants from clogging the filter plate. When not in use, the installation box and water pumps are raised to avoid the water pumps being corroded by being immersed in water for a long time. Attached Figure Description

Detailed Implementation

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] Please see Figures 1 to 9This invention provides a technical solution: a hydrodynamic control device for groundwater pollution prevention and control, comprising a top frame 1, with vertical columns 13 fixed to both sides of the top frame 1 at the front and rear ends, and the bottom of the vertical columns 13 having pointed ends; a front plate 11 fixed to the front end of the top frame 1, and a filter plate 12 fixed to the bottom of the front plate 11; a water quality monitoring sensor mounted on the surface of the filter plate 12; a mounting box 2 at the bottom of the top frame 1, and a drain plate 22 fixed to the bottom of the mounting box 2; and equidistant mounting brackets on the top of the drain plate 22. The system is equipped with multiple sets of water pumps 23. Each water pump 23 has an inlet 24 at its front bottom and a main pipe 25 connected to its rear top. The main pipe 25 extends from one side of the mounting box 2, and its exit end is connected to a connecting box 5. A delivery pipe 51 is fixed to the bottom of the other end of the connecting box 5. The top of the top frame 1 is equipped with a lifting assembly 4, which includes a winding seat 43. Three winding seats 43 are equidistantly fixed to the top of the top frame 1, and a pull rope 44 is wound onto the winding shaft of each winding seat 43. The pull rope 44 passes through the top frame 1 and is fixedly connected to the top of the mounting box 2. A cleaning component 3 is provided at the front end of the front plate 11 and the filter plate 12. The cleaning component 3 includes a mounting frame 31. Multiple water wheels 33 are rotatably mounted at equal intervals on the surface of the mounting frame 31. The positions of the water wheels 33 correspond to the water inlet 24. A sweeping plate 34 is provided at the rear end of each water wheel 33, and the sweeping plate 34 slides in contact with the outer surfaces of the filter plate 12 and the front plate 11. When using the device, it is placed downstream of the underground water body, with rows of water wheels arranged upstream. The water injection well connects the outlet pipe 51 to the external sewage treatment tank, and connects the supernatant outlet of the sewage treatment tank to the water injection well to achieve the downstream watershed treatment method. The groundwater quality is monitored by the water quality monitoring sensor on the filter plate 12. When pollution is detected, the lifting component 4 lowers the installation box 2, and the water pump 23 in the installation box 2 pumps the groundwater pollution and transports it to the sewage treatment tank for treatment through the main pipe 25. When there is no pollution, the lifting component 4 raises the installation box 2 and the water pump 23 away from the water surface to reduce the corrosion effect.

[0034] In this embodiment, sliders 21 are fixed on both sides of the mounting box 2 corresponding to the positions of the vertical columns 13, and the sliders 21 are slidably sleeved on the vertical columns 13. Heat dissipation grooves 26 are provided on the back and top of the mounting box 2. The lifting assembly 4 also includes a shaft 41. The top of the top frame 1 is rotatably mounted with the shaft 41 via bearings. The winding shaft of the winding seat 43 is fixedly connected to the shaft 41. A drive motor 42 is fixedly mounted on the top frame 1 at one end of the shaft 41, and the output end of the drive motor 42 is fixedly connected to the shaft 41. The drive motor 42 drives the shaft 41 to rotate, and the winding shafts of the three sets of winding seats 43 rotate... The reel rotates synchronously, winding up the pull rope 44. The mounting box 2 moves vertically, and its bottom leaves the water surface and enters the interior of the top frame 1. The water on the pump 23 can be drained through the bottom drain plate 22 to avoid residual water stains. When the winding seat 43 unwinds the pull rope 44, the mounting box 2 descends along the vertical column 13 by its own weight until its bottom is inserted into the water surface. The water inlet 24 of the pump 23 corresponds to and contacts the filter plate 12. The filter plate 12 blocks solid pollutants in the underground sewage. The heat dissipation grooves 26 on the back and top of the mounting box 2 can ensure the heat dissipation capacity of the pump 23 during operation.

[0035] In this embodiment, the cleaning component 3 further includes a bearing 32. A bearing 32 is provided on one side of the water wheel 33, and the bearing 32 is rotatably sleeved on the mounting bracket 31. Both ends of the mounting bracket 31 are fixedly connected to the slider 21. A connecting rod 39 is rotatably mounted on the bearing 32 corresponding to the position of the sweeping plate 34, and the sweeping plate 34 is fixedly connected to the connecting rod 39. A first gear 35 is fixed at the center of the water wheel 33, and a second gear 36 is meshed with the top of the first gear 35. A first bevel gear 37 is fixed at the axis of the second gear 36. A second bevel gear 38 is fixed at the end of the connecting rod 39 near the first bevel gear 37, and the first bevel gear 37 and the second bevel gear 38 are meshed. The second gear 36 and the first bevel gear 37 are rotatably mounted on the bearing 32. The mounting bracket 31... Fixedly connected to slider 21, the cleaning component 3 moves together with the mounting box 2, leaving or inserting into the water surface together, which can reduce corrosion of the gear structure inside the cleaning component 3. When the mounting box 2 descends, the water wheel 33 inserts into the water surface. The natural flow velocity of the groundwater and the suction generated when the water pump 23 draws groundwater provide the flow force to the surrounding water flow, thereby driving the water wheel 33 to rotate. As a result, the first gear 35 rotates with the water wheel 33 and meshes with the second gear 36. The first bevel gear 37 rotates with the second gear 36 and meshes with the second bevel gear 38. The connecting rod 39 and the sweeping plate 34 rotate with the second bevel gear 38. The sweeping plate 34 performs a circumferential cleaning of the front of the filter plate 12, cleaning up the accumulated solid pollutants and preventing blockage of the water pump 23 inlet 24.

[0036] In this embodiment, a fixing plate 58 is fixed to one side of the connecting box 5, and the fixing plate 58 is fixedly connected to the top frame 1. A plug plate 52 is slidably inserted into one end of the connecting box 5 corresponding to the main pipe 25, and the plug plate 52 extends from the upper and lower ends of the connecting box 5. The main pipe 25 is fixedly passed through the plug plate 52. A first connecting ring 53 is slidably sleeved at one end of the main pipe 25 that enters the connecting box 5, and a second connecting ring 55 is slidably sleeved on the surface of the delivery pipe 51. A return spring 54 is fixed at equal distances at the rear end of the first connecting ring 53, and the other end of the return spring 54 is fixedly connected to the outer wall of the main pipe 25. The first connecting ring 53 and the second connecting ring 55 are inserted together. A bidirectional electric push rod 56 is fixed to the bottom of the connecting box 5, and a contact plate 57 is fixed to both extended ends of the bidirectional electric push rod 56. One contact plate 57 of the bidirectional electric push rod 56 is fixedly connected to the second connecting ring 55. The length of the plug plate 52 can meet the requirements of the main pipe 25 as it moves with the mounting box 2. When moving up and down, the insert plate 52 always maintains a seal on one side of the connecting box 5, which can satisfy both the up and down movement of the main pipe 25 and the sealing of the connecting box 5. The two ends of the connecting box 5 corresponding to the insert plate 52 should also be equipped with sealing strips to improve the sealing. The main pipe 25 moves downward and gradually aligns with the delivery pipe 51. At this time, the back of the first connecting ring 53 contacts the contact plate 57 at the other end of the bidirectional electric push rod 56. The two extended ends of the bidirectional electric push rod 56 are retracted, and the first connecting ring 53 and the second connecting ring 55 are inserted. A sealing ring can also be set at the insertion position to improve the sealing. Thus, the groundwater pumped by the water pump 23 can be transported through the main pipe 25 and then sent out from the delivery pipe 51. When the bidirectional electric push rod 56 moves the two contact plates 57 away, the first connecting ring 53 slides backward under the action of the return spring 54, which facilitates the separation of the main pipe 25 and the delivery pipe 51. The movement of the mounting box 2 will not be interfered with by the delivery pipe 51.

[0037] In this embodiment, a bottom frame 6 is fixed to the bottom back of the filter plate 12, and multiple right-angle plates 61 are equidistantly mounted inside the bottom frame 6 via a rotating shaft and a torsion spring. The vertical surfaces of the right-angle plates 61 are in contact with the back of the filter plate 12. A top rod 62 is fixed to the top of each right-angle plate 61, and a ball is provided at the upper end of the top rod 62. The ball of the top rod 62 is in sliding contact with the bottom of the drain plate 22. When the mounting box 2 is pulled upward by the lifting assembly 4, the right-angle plates 61 gradually flip from a flat state to a vertical state under the elastic force of their own torsion springs. The vertical surface of the right-angle plate 61 contacts the back of the filter plate 12. This is to address the issue that the filter plate 12 is more prone to deformation due to the impact of water flow after the mounting box 2 is raised. With the support of the right-angle plate 61, the probability of deformation of the filter plate 12 can be reduced. When the mounting box 2 is raised to its highest point, the top of the top rod 62 contacts the drain plate 22. Subsequently, when the mounting box 2 is lowered, the drain plate 22 will press the ball at the top of the top rod 62 to restore the right-angle plate 61 to a flat shape, keeping it parallel to the bottom frame 6, and serving as the bottom support of the mounting box 2.

[0038] When using the device, it is placed downstream of the underground water body, with rows of injection wells arranged upstream. The outlet pipe 51 is connected to the external sewage treatment tank, and the supernatant outlet of the sewage treatment tank is connected to the injection wells to achieve downstream watershed treatment. The groundwater quality is monitored by the water quality monitoring sensor on the filter plate 12. When pollution is detected, the lifting assembly 4 lowers the installation box 2, and the water pump 23 inside the installation box 2 extracts the polluted groundwater and transports it to the sewage treatment tank for treatment through the main pipe 25. When there is no pollution, the lifting assembly 4 raises the installation box 2 and the water pump 23 away from the water surface to reduce corrosion. The drive motor 42 drives the shaft 41 to rotate, and the winding shafts of the three sets of winding seats 43 rotate synchronously to wind up the pull rope 44. As the installation box 2 moves vertically, its bottom detaches from the water surface and enters the interior of the top frame 1. The bottom drain plate 22 drains water from the pump 23, preventing residual water stains. When the winding seat 43 unwinds the pull rope 44, the installation box 2 descends along the vertical column 13 under its own weight until its bottom is submerged in the water. The inlet 24 of the pump 23 aligns with and contacts the filter plate 12, which blocks solid pollutants in the underground sewage. The heat dissipation grooves 26 on the back and top of the installation box 2 ensure the pump 23's heat dissipation capacity during operation. As the installation box 2 descends, the water wheel 33 inserts into the water surface. The natural flow velocity of the underground water and the suction generated when the pump 23 draws in groundwater provide the surrounding water flow with the force to drive the water wheel. Rotation of wheel 33 causes the first gear 35 to rotate along with the water wheel 33 and mesh with the second gear 36. The first bevel gear 37 rotates along with the second gear 36 and meshes with the second bevel gear 38. The connecting rod 39 and the sweeping plate 34 rotate with the second bevel gear 38. The sweeping plate 34 performs a circumferential cleaning of the front of the filter plate 12, removing accumulated solid contaminants and preventing blockage of the water pump 23 inlet 24. The length of the insert plate 52 is sufficient to ensure that the insert plate 52 always blocks one side of the connecting box 5 when the main pipe 25 moves up and down with the mounting box 2. This satisfies both the up-and-down movement of the main pipe 25 and the sealing within the connecting box 5. Sealing strips should also be provided at both ends of the connecting box 5 corresponding to the insert plate 52 protruding to improve sealing. As the main pipe 25 moves downwards, it gradually aligns with the delivery pipe 51. At this point, the back of the first connecting ring 53 contacts the contact plate 57 at the other end of the bidirectional electric push rod 56. The two extended ends of the bidirectional electric push rod 56 retract, and the first connecting ring 53 and the second connecting ring 55 interlock. A sealing ring can be installed at the interlocking position to improve sealing. Thus, the groundwater pumped by the water pump 23 can be transported through the main pipe 25 and then delivered out of the delivery pipe 51. When the bidirectional electric push rod 56 moves the two contact plates 57 away, the first connecting ring 53 slides backwards under the action of the return spring 54, facilitating the separation of the main pipe 25 from the delivery pipe 51. The movement of the mounting box 2 is not interfered with by the delivery pipe 51. When the mounting box 2 is pulled upwards by the lifting assembly 4...The right-angle plate 61, under the elastic force of its own torsion spring, gradually flips from a flat state to a vertical state, and the vertical surface of the right-angle plate 61 contacts the back of the filter plate 12. This is to address the issue that the filter plate 12 is more prone to deformation due to the impact of water flow after the mounting box 2 is raised. The support of the right-angle plate 61 on the back reduces the probability of deformation of the filter plate 12. When the mounting box 2 reaches its highest point, the top of the top rod 62 contacts the drain plate 22. Subsequently, as the mounting box 2 descends, the drain plate 22, by pressing the ball at the top of the top rod 62, restores the right-angle plate 61 to a flat state, keeping it parallel to the bottom frame 6, thus serving as a bottom support for the mounting box 2.
