Description
Technical Field
[0001] The utility model relates to the technical field of urban drainage pipes, in particular to an anti-backflow device for urban drainage pipes. Background Art
[0002] Sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and coping with natural disasters caused by rainwater. It can also be called a "water-elastic city". When it rains, it absorbs water, stores water, infiltrates water, and purifies water. When needed, the stored water is "released" and used. Building a sponge city, coordinating the natural ecological function and the artificial intervention function, effectively controlling rainwater runoff, and realizing the urban development mode of natural accumulation, natural infiltration, and natural purification is conducive to repairing the urban water ecology, conserving water resources, enhancing the city's flood prevention capacity, expanding the effective investment of public products, improving the quality of new urbanization, and promoting the harmonious development of man and nature.
[0003] A sponge city drainage channel disclosed in publication number CN219527869U improves the problem of over-complexity in drainage channel assembly.
[0004] However, this sponge city drainage channel has the following disadvantages:
[0005] Drainage channels are used to discharge accumulated water on urban roads and sewage from residents. When discharging these sewage, if sewage backflows, sewage may flow back into residential areas or office areas, polluting the environment and posing a threat to human health.
[0006] As an urban drainage pipe, when the accumulated water on the road is discharged through the urban drainage pipe, foreign objects and garbage will enter the pipe together, which will cause the pipe to be blocked for a long time, and the accumulated water cannot be discharged, resulting in waterlogging. Utility Model Content
[0007] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a device for preventing backflow of urban drainage pipes, thereby solving the problems raised in the above-mentioned background technology.
[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:
[0009] A device for preventing water backflow in urban drainage pipes comprises: a drainage channel, a partition plate is fixedly connected to the middle of the top of the drainage channel, a flow hole is opened on the surface of the partition plate, an anti-backflow component for preventing water backflow is fixedly connected to the surface of the flow hole, and filtering components for filtering impurities inside the urban drainage are arranged inside the two ends of the drainage channel.
[0010] Optionally, the anti-reverse component includes a spring fixedly connected to the surface of the flow hole, one end of the spring is fixedly connected to a blocking ball, a conical square tube is provided inside the drainage channel and on one side of the blocking ball, and the outer surface of the conical square tube is wide on the left and narrow on the right.
[0011] Optionally, the filtering assembly includes a water tank arranged at both ends of the drainage channel, the inner wall of the water tank is provided with a pad, the surface of the pad is provided with a frame plate, the inner wall of the frame plate is provided with a filter net for filtering impurities inside the water flow, and handles are axially symmetrically provided on both sides of the top of the frame plate, and there are two handles.
[0012] Optionally, a conical square cylinder is provided inside the drainage channel and on one side of the blocking ball. The outer surface of the conical square cylinder is wide on the left and narrow on the right. The surface of the blocking ball is sleeved on the inside of the conical square cylinder, and a through hole smaller than the diameter of the blocking ball is provided at one end of the conical square cylinder. The design of the conical square cylinder allows the blocking ball to be affected by the spring force and to be fixed inside the conical square cylinder, thereby blocking the flowing water and preventing backflow.
[0013] Optionally, a water tank cover is provided on the top of the water tank, and a plurality of water-permeable grooves for circulating water are provided on the top of the water tank cover in a rectangular array. The design of the water-permeable grooves enables water to flow into the water tank through the water-permeable grooves when water accumulates on the urban road surface, thereby completing the discharge of water accumulated on the urban road.
[0014] Optionally, square grooves for conveying drainage are provided on both sides of the water reservoir, and there are two square grooves. The design of the square grooves allows the water source inside the drainage channel to remain in a flowing state.
[0015] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:
[0016] 1. The anti-backflow device for urban drainage pipes, through the setting of anti-backflow components, when the drainage channel is used as the drainage pipe in the urban road, when the sewage inside the drainage channel passes through the conical square tube, the water flow will enter from the through hole at one end of the conical square tube and begin to impact the barrier ball, so that the barrier ball is impacted by the water flow to generate pressure and compress the spring, thereby causing the barrier ball to move inside the conical square tube. At this time, the water flow can continue to flow from the inside of the conical square tube to one side of the partition plate. When backflow occurs, the water flow flows in the opposite direction, and the barrier ball has no pressure generated by the impact of the water flow. It will be affected by the spring elastic force, and the barrier ball will be firmly pressed inside the conical square tube, thereby preventing the water flow from passing through, thereby avoiding the backflow of sewage, and avoiding backflow to residential areas or office areas, playing a role in protecting the environment and protecting human health.

The city drainage pipe anti-backflow device, through the setting of filtering components, when the accumulated water on the city road surface enters the water tank through the permeable groove, the foreign matter and garbage in the accumulated water will be filtered by the filter net, thereby preventing the accumulated water from carrying foreign matter and garbage to flow inside the drainage channel and causing blockage. At the same time, the staff can regularly open the pool cover, pull the handle, and clean the foreign matter and garbage on the filter net, thereby ensuring the cleanliness of the water flow inside the drainage channel, avoiding pipe blockage and improving drainage efficiency.
