When the water pump works again, it will extract the water in the soil through the filter pipe and discharge it out through the outlet pipe to achieve the purpose of precipitation.

[0014] The present invention has the following beneficial effects: 1. In the present invention, when the water pump extracts water from the soil around the channel, the water in the soil will be extracted by the water pump through the filter tube and discharged outward. When the water is extracted and flows, it will flow through the filter plate. When the water flows again, it will carry soil through the filter plate. When the surface of the filter plate is blocked by the water flow carrying soil, a closed space will be formed inside the main body and the filter tube. When the water pump continues to extract, the negative pressure generated by the rotating plate during extraction will transmit the adsorption force to the filter plate through the multiple holes on the inner plate. The bottom of the inner plate slides upward under the adsorption of suction. When the sliding plate slides upward, it pushes the hollow tube to slide outward through multiple rotating plates. When the multiple hollow tubes slide outward on the surface of the filter tube, they push the filter plate to slide outward and also generate an outward supporting force for the stones inside the channel. When the multiple filter plates support outward, it can reduce the density of the stones after being washed by the water flow when the water flow carries the soil, causing the soil to block the spaces between the stones, affecting the flow speed of the water when it is extracted, thereby increasing the precipitation rate of precipitation.

[0015] 2. According to the present invention, when the sliding disk slides upward after being subjected to the adsorption force, the upward sliding of the sliding disk will drive the fixed frame and the center ring to slide synchronously on the surface of the central shaft. When the center ring slides upward, it will slide upward in the threaded groove on the outer surface of the central shaft through the internal insertion rod and drive the central shaft to rotate while sliding. When the central shaft rotates, it will drive the cross-tooth plate to rotate synchronously. When the cross-tooth plate rotates, it will push the bevel gear and the gear rod to slide outward on the fixed frame 2. When the gear rod slides outward under the rotation of the cross-tooth plate, the gear rod will also rotate while sliding through the meshing of the bevel gear and the cross-tooth plate when the cross-tooth plate rotates. When the gear rod slides, it will slide into the inside of the rectangular groove through the fixed frame 2 and the hollow tube and mesh with a plurality of auxiliary teeth inside the rectangular groove. Then, after the gear rod meshes with the auxiliary teeth, The surface of the auxiliary tooth slides backward while rotating. When the gear rod rotates, it will drive the filter plate to slide upward on the surface of the hollow tube through the auxiliary teeth. Then, when the outer top of the cross-tooth plate passes the side wall of the bevel gear, the bevel gear is reset under the action of the tension spring and drives the gear rod to disengage from the auxiliary tooth. At this time, the filter plate will be pulled downward by the limit spring 2. When the filter plate slides up and down, the surface of the filter plate will rub against the stones. The friction between the filter plate and the stones can remove the soil blocked on the surface of the filter plate, causing the soil to fall off the surface of the filter plate, thereby restoring the water flow capacity of the filter plate and reducing the impact of soil on the flow of water on the filter plate when the filter plate is reset. This can reduce the impact of soil on the flow of water on the filter plate when it is blocked for a long time, thereby improving the precipitation effect.

[0016] 3. In the present invention, when the filter plate is pushed outward and reset by the hollow tube, it will slide back and forth. When the filter plate slides upward, it will drive the cleaning ring to slide upward through the reset of the movable plate and the telescopic spring rod. At the same time, when the filter plate slides outward, the filter plate inside the cleaning ring will slide outward under the elastic force of the auxiliary spring and contact the side wall of the filter plate. Then, when the cleaning ring drives the arc-shaped cleaning plate extending outward to slide upward, it will scrape between the side wall of the filter plate and the side wall of the filter tube. Then, when the filter plate is reset, it will compress the arc-shaped cleaning plate to make it slide into the inside of the cleaning ring. Then, when the movable plate is reset, it will push the movable plate to the inside of the cleaning ring. The movable cleaning ring slides downward, and the dirt on the movable plate and the side walls of the filter tube are scraped off when the cleaning ring and the arc-shaped cleaning plate slide back and forth, thereby reducing the situation in which the dirt adheres to the surface of the filter tube when the dirt passes through the gap of the filter plate and the filter tube with the water flow into the interior of the filter tube after the filter plate slides outward, and reducing the situation in which the surface of the filter tube is clogged due to the dirt adhering to the surface of the filter tube after the filter plate slides outward. The sliding cleaning on the side walls of the filter tube and the filter plate can further enhance the cleaning of the dirt adhesion and can also enhance the outward flow speed of water during precipitation, thereby further enhancing the precipitation efficiency.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] A method for using a foundation pit dewatering device, a foundation pit dewatering device, the method comprising the following steps: S1: Excavating a channel: First, a cylindrical channel is excavated around the foundation pit as required, and then the filter assembly 11 is connected to the main body 1, and then the main body 1 is placed inside the channel and stones are filled between the main body 1 and the channel; S2: Placement and sealing: Then, place the water pump 121 with the water outlet pipe 122 inside the main body 1 so that it contacts the inner plate 111, and then install the vacuum plug 123 on the top of the main body 1 to seal it; S3: Extracting precipitation: After completion, the water pump 121 is started. When the water pump 121 works again, it will extract water in the soil through the filter pipe 101 and discharge it out through the outlet pipe 122 to achieve the purpose of precipitation.

[0032] When in use, first dig a cylindrical channel around the foundation pit as needed, then connect the filter assembly 11 to the main body 1, then place the main body 1 inside the channel and fill stones between the main body 1 and the channel, then place the water pump 121 with the outlet pipe 122 inside the main body 1 so that it contacts the inner plate 111, then install the vacuum plug 123 on the top of the main body 1 to seal it, and after completion, start the water pump 121. When the water pump 121 works again, it will extract water in the soil through the filter tube 101 and discharge it outward through the outlet pipe 122 to achieve the purpose of precipitation.

[0033] When the water pump 121 extracts water from the soil around the channel, the water in the soil will be extracted by the water pump 121 through the filter tube 101 and discharged outward. When the water is extracted and flows, it will flow through the filter plate 312. When the water flows again, it will carry soil through the filter plate 312. When the surface of the filter plate 312 is blocked by the flow of soil carried by the water, a closed space will be formed inside the main body 1 and the filter tube 101. When the water pump 121 continues to extract, the negative pressure generated by the rotating plate 212 during extraction will transmit the adsorption force to the filter plate 312 through the multiple holes on the inner plate 111. The bottom of the inner plate 111 slides upward under the adsorption of suction. When the sliding plate 213 slides upward, it pushes the hollow tube 311 to slide outward through the multiple rotating plates 221. When the multiple hollow tubes 311 slide outward on the surface of the filter tube 101, they push the filter plate 312 to slide outward and also generate an outward supporting force for the stones inside the channel. When the multiple filter plates 312 support outward, it can reduce the density of the stones after being washed by the water flow when the water flow carries the soil, causing the soil to block the space between the stones, affecting the flow speed of the water when it is extracted, thereby increasing the precipitation rate of precipitation.

[0034] Since the adsorption force of the water pump 121 is relatively large, when the sliding disc 213 slides under the influence of the adsorption force, it will push the filter plate 312 to slide outward. When the filter plate 312 slides outward after being pushed, the sliding of multiple filter plates 312 supports the stones and the water flows through the gaps between the multiple filter plates 312 and between the filter plates 312 and the filter tube 101 to enter the interior of the filter tube 101 for extraction. When the water flows through the gap into the interior of the main body 1, the enclosed adsorption force inside the main body 1 will disappear. When the enclosed adsorption force disappears, the sliding disc 213 will be reset under the pulling action of the reset spring, and the filter plate 312 will be reset synchronously with the sliding disc 213.

[0035] When the sliding plate 213 slides upward after being attracted, the upward sliding of the sliding plate 213 drives the fixing frame 411 and the center ring 412 to slide synchronously on the surface of the center shaft 413. When the center ring 412 slides upward, it slides upward in the thread groove on the outer surface of the center shaft 413 through the internal insertion rod and drives the center shaft 413 to rotate while sliding. When the center shaft 413 rotates, it drives the cross tooth plate 421 to rotate synchronously. When the cross tooth plate 421 rotates, it drives the bevel gear 423 and The gear rod 424 slides outward on the second fixing frame 422. When the gear rod 424 slides outward under the rotation of the cross tooth plate 421, the gear rod 424 will also rotate while sliding through the meshing of the bevel gear 423 and the cross tooth plate 421 when the cross tooth plate 421 rotates. When the gear rod 424 slides, it will slide through the second fixing frame 422 and the hollow tube 311 to the inside of the rectangular groove 313 and mesh with several auxiliary teeth inside the rectangular groove 313. Then, the gear rod 424 rotates while sliding. After the rod 424 is meshed with the auxiliary teeth, it will slide backward on the surface of the auxiliary teeth and rotate at the same time. When the gear rod 424 rotates, it will drive the filter plate 312 to slide upward on the surface of the hollow tube 311 through the auxiliary teeth. Then, when the outer top of the cross-tooth plate 421 passes the side wall of the bevel gear 423, the bevel gear 423 is reset under the action of the tension spring and drives the gear rod 424 to disengage from the auxiliary teeth. At this time, the filter plate 312 will be pulled downward by the limit spring 2. When the filter plate 312 When sliding up and down, the surface of the filter plate 312 and the stones will rub against each other. The friction between the filter plate 312 and the stones can remove the mud blocking the surface of the filter plate 312, causing the mud to fall off the surface of the filter plate 312, thereby restoring the water flow capacity of the filter plate 312 and reducing the blockage of the mud on the filter plate 312 when the filter plate 312 is reset. In addition, the blockage of the filter plate 312 by the mud for a long time can reduce the impact on the flow of water, thereby improving the precipitation effect.

[0036] When the filter plate 312 is pushed outward and reset by the hollow tube 311, it will slide back and forth. When the filter plate 312 slides upward, it will drive the cleaning ring 322 to slide upward through the reset of the movable plate 321 and the telescopic spring rod 323. At the same time, when the filter plate 312 slides outward, the filter plate 312 inside the cleaning ring 322 will slide outward under the elastic force of the auxiliary spring and contact the side wall of the filter plate 312. Then, when the cleaning ring 322 drives the arc-shaped cleaning plate 324 extending outward to slide upward, it will scrape between the side wall of the filter plate 312 and the side wall of the filter tube 101. Then, when the filter plate 312 is reset, it will compress the arc-shaped cleaning plate 324 to make it slide into the inside of the cleaning ring 322. Then, when the movable plate 321 is reset, it will pass through the movable plate 3 21 pushes the cleaning ring 322 to slide downward, and when the cleaning ring 322 and the arc-shaped cleaning plate 324 slide back and forth, the dirt on the movable plate 321 and the side wall of the filter tube 101 will be scraped off, thereby reducing the situation in which the dirt adheres to the surface of the filter tube 101 when the dirt passes through the gap of the filter plate 312 and the filter tube 101 with the water flow into the interior of the filter tube 101 after the filter plate 312 slides outward, and reducing the situation in which the surface of the filter tube 101 is clogged due to the dirt adhered to after the filter plate 312 slides outward. By sliding cleaning on the side walls of the filter tube 101 and the filter plate 312, the cleaning of the dirt adhesion can be further enhanced, and the outward flow speed of the water flow during precipitation can also be enhanced, thereby further enhancing the precipitation efficiency.
