Description

Technical Field

[0001] The utility model relates to the technical field of pollution control, in particular to a permeable reaction wall for groundwater pollution control. Background Art

[0002] Groundwater pollutants mainly come from hazardous waste disposal sites, septic tanks, underground sewage pipe leaks, pesticide and fertilizer residues carried in agricultural runoff, urban garbage and highway waste, underground or open-pit mines, contaminated surface water, underground oil storage tanks and oil pipeline leaks, and accidental leaks of organic liquids.

[0003] For example, the Chinese utility model patent with patent publication number CN215975015U includes a reaction wall and a base, wherein a slot is arranged on the top surface of the base, the reaction wall is hollow and has a plurality of water holes arranged perpendicular to the water flow direction, and a socket adapted to the slot is arranged on the bottom surface of the reaction wall. At the same time, the interior of the reaction wall of the patent is divided into a plurality of reaction chambers, so that each reaction chamber can be repaired and maintained separately during repair and maintenance, thereby reducing the maintenance cost and the difficulty of later repair. However, although the patent allows the entire wall to be removed from the base for inspection and repair when the wall is damaged; the wall is divided into a plurality of reaction chambers, and each of them is provided with a top cover, so that the reaction chamber can be repaired and maintained separately. The invention can realize one-time inspection and maintenance, which reduces the difficulty of later maintenance. However, when the wall is pulled out, the sewage is still flowing because it is not stopped. The polluted water flows into the treated clean water area without being blocked, causing the treated clean groundwater to be polluted again. At the same time, since the subsequent water area is a planned clean water area, the only way to treat it again is to install the infiltration reaction wall again, which will undoubtedly greatly increase the cost of groundwater pollution control. At the same time, when the infiltration reaction wall is repaired later, the same problems as above will arise, thus entering a vicious circle. In view of this, we propose a infiltration reaction wall for groundwater pollution control. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and to provide a permeable reaction wall for groundwater pollution control, which can solve the problem of sewage continuing to flow after the wall is extracted.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A permeable reaction wall for groundwater pollution control comprises a base, wherein two relatively arranged fixed walls are fixedly connected to the upper portion of the base, a filter wall is fixedly connected between the two fixed walls, a filter plate is slidably connected to the inside of the filter wall, the upper surface of the filter plate extends out of the upper surface of the filter wall, a sliding groove is provided on one side surface of the two fixed walls, and a stop plate is slidably connected to the inside of the sliding groove.

[0007] A driving groove is provided on the rear surface of the intercepting plate, and the driving groove is arranged to be inclined as a whole. A locking groove is provided on the inner wall of the driving groove. Rotation grooves are closed and opened on the left and right surfaces of the filter plate, and an intercepting structure is arranged inside the rotation groove.

[0008] Preferably, the stopping structure includes two rotating shafts, both of which are rotatably connected to the inner wall of the rotating groove, the outer surfaces of the two rotating shafts are respectively sleeved with clamping blocks, the side surfaces adjacent to the two clamping blocks are provided with arc grooves, the outer surfaces of the two rotating shafts are both sleeved with gears, the two gears are meshed with each other, the outer surface of the upper rotating shaft is sleeved with a worm wheel, the outer surface of the worm wheel is meshed with a worm, the upper end of the worm rotates to pass through the upper surface of the filter plate, and the inside of the driving groove is slidably connected to a driving rod.

[0009] Preferably, a locking block is provided at one end of the driving rod close to the driving groove, the locking block is adapted to the locking groove, the driving rod is adapted to the two arc grooves, the interior of the driving rod is set to be hollow, and the outer surface of the driving rod is fixedly connected to a spring.

[0010] Preferably, the other end of the spring is fixedly connected to a pressing block, and one end of the pressing block close to the driving rod is fixedly connected to a displacement column.

[0011] Preferably, the other end of the displacement column slides through the interior of the driving rod, and the locking block slides through the interior of the driving rod.

[0012] Preferably, a return spring is sleeved on the outer surface of one end of the locking block located inside the driving rod, and the other end of the return spring is fixedly connected to the inner wall of the driving rod.

[0013] Preferably, a support sleeve is fixedly connected to the inner wall of the driving rod, and an internal sliding sleeve of the support sleeve is provided with two displacement plates, and upper and lower side surfaces of the two displacement plates are provided with inclined grooves.

[0014] Preferably, the oblique grooves on the two displacement plates are arranged oppositely, the front surface of the right displacement plate is fixedly connected to the front locking block, and the rear surface of the left displacement plate is fixedly connected to the rear locking block.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) When the filter plate is damaged or needs to be repaired or replaced, the filter plate is pulled up and the filter plate rises to cooperate with the interception structure and the driving groove to make the two interception plates close to each other. When the filter plate is pulled out, the water flow is intercepted by the interception plate. Through the above structure, when the filter plate is replaced or repaired, the interception structure can automatically drive the interception plate to intercept the water flow, thereby avoiding the problem of untreated water entering the treated water area due to the weakening of the filtering effect and causing secondary pollution.

[0017] (2) In the infiltration reaction wall for groundwater pollution control, after the displacement column moves, it cooperates with two oppositely arranged inclined grooves to drive the two displacement plates to move. At the same time, since the inclined grooves are oppositely arranged, the two displacement plates will move in opposite directions. At the same time, since the front surface of the right displacement plate is fixedly connected to the front locking block, and the rear surface of the left displacement plate is fixedly connected to the rear locking block, the two displacement plates will drive the two locking blocks to retract into the inside of the driving rod, thereby unlocking the driving rod, and then the filter plate can be lifted and pulled. After lifting, the worm gear is rotated in the opposite direction to relock the driving rod. Through the above structure, when the filter plate is pulled out, it can be directly pulled out by rotating the worm gear, and the driving rod will not fall again due to gravity after it is raised, so that when reinstalling, it only needs to repeat the operation, reducing the complexity of the operation.

Through the above structure, when the filter plate 4 is replaced or repaired, the stopping structure can automatically drive the stopping plate 6 to stop the water flow, thereby avoiding the problem of untreated water entering the treated water area due to the weakening of the filtering effect and causing secondary pollution.

[0028] Furthermore, the stop structure includes two rotating shafts 10, both rotating shafts 10 are rotatably connected to the inner wall of the rotating groove 9, the outer surfaces of the two rotating shafts 10 are respectively sleeved with clamping blocks 11, and the side surfaces of the two clamping blocks 11 are close to each other. The outer surfaces of the two rotating shafts 10 are sleeved with gears 13, and the two gears 13 are meshed with each other. The outer surface of the upper rotating shaft 10 is sleeved with a worm wheel 14, and the outer surface of the worm wheel 14 is meshed with a worm 15. The upper end of the worm 15 rotates and penetrates the upper surface of the filter plate 4. The inside of the driving groove 7 is slidably connected with a driving rod 16, and a locking block 17 is provided at one end of the driving rod 16 close to the driving groove 7. The locking block 17 is adapted to the locking groove 8, and the driving rod 16 is adapted to the two arc grooves 12.

[0029] Working principle: By rotating the worm 15, the worm 15 synchronously drives the worm wheel 14 to rotate. After the worm wheel 14 rotates, it drives the upper gear 13 to rotate through the upper rotating shaft 10.

After the two clamping blocks 11 rotate, they clamp the driving rod 16 and squeeze the pressing block 19 while clamping. After the pressing block 19 is squeezed, the spring 18 is compressed, and the displacement column 20 is driven to move at the same time. After the displacement column 20 moves, it cooperates with two oppositely arranged inclined slots 24 , driving the two displacement plates 23 to move. At the same time, since the inclined grooves 24 are arranged in opposite directions, the two displacement plates 23 will move in opposite directions. At the same time, since the front surface of the right displacement plate 23 is fixedly connected to the front locking block 17, and the rear surface of the left displacement plate 23 is fixedly connected to the rear locking block 17, the two displacement plates 23 will drive the two locking blocks 17 to retract into the inside of the driving rod 16, thereby unlocking the driving rod 16, and then pulling the filter plate 4. After pulling, the worm 15 is rotated in the opposite direction to relock the driving rod 16.
