AI Technical Summary
The anti-blocking devices in the existing subway water supply and drainage system lack anti-backflow function, which may cause ground water to flow back into the subway station during heavy rainfall, affecting passenger safety and equipment operation.
An anti-clogging device for subway water supply and drainage has been designed, which includes a main mechanism and an anti-backflow mechanism. The coordination of a counterweight block, a mounting block, a baffle, and a magnetic block is used to ensure that the baffle always fits the bottom of the drainage tube. The limiting buffer block and the sealing sheet are combined to achieve sealing. At the same time, multi-stage filtration through the mounting frame, filter cartridge, and grille cover prevents clogging by debris.
It effectively prevents backflow, ensures smooth water flow, prevents sewer liquid backflow, avoids equipment damage, and prevents downstream pipeline blockage through multi-stage filtration, keeping the environment in the subway station clean and the equipment running stably.

Description
Technical Field
[0001] The utility model relates to the technical field of subway water supply and drainage, in particular to an anti-blocking device for subway water supply and drainage. Background Art
[0002] The subway is an urban public transportation system that is usually located in underground tunnels, but may also run on the ground or on viaducts. The subway (also known as underground railway, underground railway or simply "subway") is an urban rail transit system located underground or above the ground. It is a modern public transportation tool that can run on fixed tracks through electric traction vehicles, providing a convenient, fast and safe way of travel. In summary, the subway is an efficient urban public transportation tool designed to provide urban residents with a fast, reliable and safe way of travel.
[0003] The subway water supply and drainage system is a crucial component of subway stations and the tunnels along the lines. It provides essential domestic water and removes sewage, wastewater, and rainwater generated within the stations. The water supply and drainage system is crucial for ensuring the normal operation of subway stations and the safety of passengers. Comprising a combination of water supply and drainage systems, the stable operation of the subway water supply and drainage system is crucial for ensuring passenger safety and maintaining a clean subway station environment. With technological advancements, future water supply and drainage systems may integrate more intelligent technologies and sustainable development strategies to improve efficiency and environmental performance.
[0004] Anti-clogging drains are widely used in subway drainage systems. The anti-clogging drains in the existing technology usually do not have an anti-backflow function. Although they meet the use requirements to a certain extent, it is found in actual use that in heavy rainfall weather, if the drains do not have an anti-backflow function, ground water may flow back into the subway station, affecting passenger safety and equipment operation. Utility Model Content
[0005] The purpose of the present utility model is to provide an anti-blocking device for subway water supply and drainage, so as to solve the problems raised in the above-mentioned background technology.
[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an anti-blocking device for subway water supply and drainage, comprising a main body mechanism, a backflow prevention mechanism fixedly installed at the bottom of the main body mechanism, the backflow prevention mechanism comprising a second drainage cylinder, mounting blocks are rotatably installed on the left and right sides of the bottom of the second drainage cylinder, a block is fixedly installed inside the second drainage cylinder, a block is fixedly installed on the side of the mounting block close to the block, a counterweight is fixedly installed on the side of the mounting block away from the mounting block, the second drainage cylinder is fixedly installed at the bottom of the main body mechanism, and the block is arranged at the top of the joint between the two sets of block plates.
[0007] Preferably, limit buffer blocks are fixedly installed on both the left and right sides of the second drainage cylinder.
[0008] Preferably, sealing sheets are fixedly mounted on the bottoms of the second drain cylinder and the stopper.
[0009] Preferably, a magnetic block is fixedly mounted on the top of the stop block.
[0010] Preferably, the main body structure includes a mounting frame, a first drainage cylinder is fixedly installed on the bottom of the mounting frame, a first mounting groove is provided on the top of the first drainage cylinder, a filter cartridge is movably installed on the top of the first mounting groove, a plurality of filter holes are provided on the outer wall of the filter cartridge, a second mounting groove is provided on the top of the mounting frame, and a grille cover is movably installed on the top of the second mounting groove.
[0011] Preferably, an extension rod is fixedly installed inside the filter cartridge, and a handle is fixedly installed on the top of the extension rod.
[0012] Preferably, a disassembly hole is provided on one side of the grille cover, and a water guide slope is provided inside the mounting frame.
[0013] Compared with the prior art, the beneficial effects of the present invention are: the anti-blocking device for subway water supply and drainage;
[0014] 1. The coordination between the counterweight, mounting block, and baffle ensures that the baffle always adheres to the bottom of the second drain cylinder without external interference. This in turn ensures that the baffle always adheres to the bottom of the second drain cylinder and the baffle, sealing the bottom of the second drain cylinder and preventing sewer liquid from flowing back. When water flows down from the interior of the main mechanism, the baffle overcomes the force of the counterweight and tilts downward to complete drainage. After drainage is completed, the baffle automatically resets under the action of the counterweight.
[0015] During the above process, the blocking piece is magnetically attracted to the bottom of the blocking piece by the magnetic block to ensure stable fixation, and the sealing piece ensures the sealing of the joints between the blocking piece, the second drainage cylinder and the blocking piece. The limiting buffer block limits the inclination angle of the mounting block and cushions the impact of the counterweight block to prevent the mounting block from excessive rotation or the counterweight block from hitting the second drainage cylinder and causing damage;
[0016] 2. The device is installed on the mounting frame, and the water flow is guided through the first drainage cylinder for drainage. The water flow inside the first drainage cylinder is filtered by the cooperation between the filter cartridge and the filter holes. Large particles of debris are intercepted by the filter holes and stored inside the filter cartridge, preventing blockage of the downstream pipeline.
[0017] In the above process, larger debris is filtered through the grille cover to achieve multi-stage filtration. The cooperation between the extension rod and the handle allows the staff to directly lift the filter cartridge through the handle when cleaning it to avoid direct contact with the garbage at the bottom of the filter cartridge. The disassembly hole makes it easy for the staff to disassemble the grille cover, and the water flow is guided by the water guide slope to maintain smooth water flow.
