[0002] The water supply and drainage project is a project used to deal with water supply, wastewater discharge and water quality improvement. It is one of the basic infrastructure for the development of cities and industries, and is also a major component of municipal engineering. The anti-seepage and water-stopping structure of the water supply and drainage project is usually located on the inner side of the main sewage pipe and the branch sewage pipe. The anti-seepage and water-stopping structures in the existing technology have limited anti-seepage and water-stopping effects and are not convenient for filtering garbage in the sewage introduced into the main sewage pipe. For this reason, application number: 202121820036.6 discloses an anti-seepage and water-stopping structure based on the water supply and drainage project, including: a main sewage pipe, a branch sewage pipe is arranged on the right side of the main sewage pipe, and the main sewage pipe and the branch sewage pipe A transfer pipe is provided on the inner side; a flange is fixedly connected to the inner and outer sides of the main sewage pipe and the branch sewage pipe, and flanges are fixedly connected to the outer sides of the left and right ends of the transfer pipe; a stop valve is installed on the inner side of the middle part of the transfer pipe, and a filter screen that is engaged with the transfer pipe is provided on the left side of the stop valve; a sealing plate is provided on the right side of the stop valve; the anti-seepage and water-stopping structure based on the water supply and drainage project is convenient for installing the anti-seepage and water-stopping structure on the inner side of the main sewage pipe and the branch sewage pipe, and at the same time, it has good anti-seepage and water-stopping and backflow prevention effects, and is convenient for filtering garbage in the sewage introduced into the main sewage pipe to prevent it from flowing into the branch sewage pipe;

[0003] The above patent discloses an anti-seepage and water-stopping structure based on a water supply and drainage project, which can achieve the purpose of preventing water seepage, backflow and filtering garbage by setting a sealing gasket, an anti-backflow structure and a filter net. However, its anti-seepage and water-stopping effect has not been effectively improved, which is mainly reflected in the following points: 1. It cannot reduce the impact of sewage. When the impact force of sewage is large, the sealing gasket is easily damaged by the impact, which in turn causes the risk of seepage and leakage; 2. The filtered garbage cannot be discharged and cleaned in time, and the filter net is prone to blockage due to the static accumulation of garbage after long-term filtration. When the filter net is blocked, the sewage cannot flow, resulting in sewage backflow and seepage; based on the above situation, we have redesigned and proposed an anti-seepage and water-stopping structure based on a water supply and drainage project.

[0028] Working principle: When in use, when sewage enters the main drainage pipe 101, the sewage first passes through the water hole 11 on the left, the filter screen 10 on the left and the one-way valve 9 on the left to hit the two triangular guide plates 8. The sewage follows the inclined surface of the triangular guide plate 8 and hits the top of the fan-shaped diverter block 4. The fan-shaped diverter block 4 diverts the sewage to both sides. The diverted sewage passes through the diverter hole on the diverter plate 1 and enters the three-way diverter pipe 100 through the sealing ring 103. At this time, the filter screen 10 on the left blocks the garbage in the sewage at its top. When the sewage hits the triangular guide plate 8, the sewage will enter the three-way diverter pipe 100 through the sealing ring 103. When the sewage is on the guide plate 8, the impact force of the sewage will be unloaded for the first time. When the sewage hits the fan-shaped diversion block 4, the sewage will be diverted, which can unload the impact force of the sewage for the second time. When the sewage flows through the diversion plate 1, the sewage will be diverted again, so that the sewage can be unloaded for the third time. By unloading the sewage multiple times, the flow rate of the sewage flowing through the sealing ring 103 is significantly reduced, thereby significantly reducing the impact force on the inner wall of the sealing ring 103, thereby effectively reducing the risk of damage to the sealing ring 103 due to the large impact force, and achieving the purpose of preventing the sealing ring 103 from being damaged and leaking;

[0029] The threshold of the extrusion pressure is set in advance by the controller 2. When the sewage hits the fan-shaped diverter block 4, the fan-shaped diverter block 4 will be squeezed to move downward. The fan-shaped diverter block 4 drives the pressure sensor 5 to squeeze the guide rod 6 and transmits the detected pressure value to the controller 2. The pressure sensor 5 detects the reaction force of the extrusion. When the water flow is small, the extrusion pressure will decrease. When it is detected that the extrusion pressure is lower than the threshold, it proves that the filter plate 10 on the left is blocked. At this time, the controller 2 controls the sound and light alarm 3 to emit a sound and light alarm to remind personnel. At the same time, the controller 2 controls the multi-stage electric telescopic rod 13 on the left to start in reverse, and controls the multi-stage electric telescopic rod 13 on the right to open forward. The multi-stage electric telescopic rod 13 on the left drives the blocking plate 12 on the left to move right to block the water hole 11 on the left. The multi-stage electric telescopic rod 13 on the right drives the blocking plate 12 on the right to move right to release the blockage of the water hole 11 on the right. At this time, the sewage is converted to pass through the water hole 11 on the right and the filter plate on the right. After cleaning, the left filter screen plate 10 can be moved back into the main drainage pipe 101. When the pressure sensor 5 detects that its squeezing force is lower than the threshold value again, the multi-stage electric telescopic rod 13 on the left is controlled to start forward and the multi-stage electric telescopic rod 13 on the right is controlled to open in the reverse direction, so that the water hole 11 on the left is opened and the water hole 11 on the right is blocked. At this time, the sewage is converted to enter through the water hole 11 on the left again, and the filter screen plate 10 on the right can be moved out for cleaning, thereby achieving the purpose of automatic alternating filtration of the two filter screen plates 10 and being able to remind personnel in time when cleaning is needed. By automatically alternating filtration and reminding personnel to clean, the risk of water backflow and seepage caused by clogging of the filter screen plate 10 can be effectively reduced, and the stability of anti-seepage can be improved.

[0030] In addition, the setting of the one-way valve 9 allows water to flow out in one direction only, and there will be no situation where the water that has flowed out will flow back and seep out again, thereby achieving the effect of preventing backflow and stopping water.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
