Description

Technical Field

[0001] The present application relates to the technical field of municipal road drainage, and in particular to a road drainage filtering structure. Background Art

[0002] Road drainage structure is a common structure, which is mainly used to drain the accumulated water or rainwater on the road surface into the sewer to reduce the accumulation of water on the road. During the drainage process, multiple diversion pipes drain the accumulated water on the road surface into the drainage pipes. The drainage capacity of the drainage pipes is large, and the diversion pipes are prone to carry mud, fallen leaves, etc. into the drainage pipes while guiding the accumulated water on the road surface. The blockage of the drainage pipes and the cleaning of debris are common problems.

[0003] The utility model patent with announcement number CN206888164U proposes a road drainage filtering device, including a water inlet component with a water inlet arranged vertically upward, the water inlet upper cover is provided with a filter plate, the water inlet component has a rotating shaft arranged horizontally and laterally inside and along its center line, the rotating shaft is connected to at least one rotating wheel which is rotated by the impact of the water flow and drives the rotating shaft to rotate, the rotating shaft is meshed with a transmission shaft arranged vertically upward through a bevel gear, and a cleaning member connected to the upper end of the transmission shaft and capable of rotating along the upper surface of the filter plate is provided on the upper surface of the filter plate.

[0004] The above-mentioned device cannot effectively filter small particles of gravel and soil in rainwater. Gravel and soil will still flow into the municipal drainage system with rainwater and settle and accumulate in the drainage system, which will cause blockage of the municipal drainage system after a long time. Utility Model Content

[0005] The purpose of the utility model is to solve or at least alleviate the problem that the existing devices are unable to filter small particles of soil and gravel, resulting in the gravel and soil still flowing into the municipal drainage system with rainwater and settling and silting in the drainage system, which can easily cause blockage of the municipal drainage system after a long time.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A road drainage and filtering structure comprises a vertically arranged water filter pipe, a filtering structure is installed in the inner cavity of the water filter pipe, a storage assembly for storing impurities is installed on one side of the water filter pipe, a drainage assembly is also provided below the storage assembly, a horizontally arranged sedimentation pipe is connected to the bottom end of the water filter pipe, a drainage pipe is fixedly connected to the bottom wall of the sedimentation pipe at one end away from the water filter pipe, two groups of water retaining blocks are provided in the inner cavity of the sedimentation pipe, a plurality of water retaining blocks in the two groups are alternately staggered along the length direction of the sedimentation pipe, and a collection box is detachably connected to the lower surface of the middle section of the sedimentation pipe.

[0008] By adopting the above technical scheme, after the surface water on the road is collected, it enters the inner cavity of the filter pipe through the top of the filter pipe and is initially filtered by the first filter screen. Since the first filter screen is inclined, large particles of impurities that cannot pass through the first filter screen slide down along the first filter screen under the impact of rainwater and its own gravity and enter the inner cavity of the sewage storage pipe for storage. Part of the rainwater that enters the sewage storage pipe with the impurities passes through the second filter screen and flows back along the return pipe to the bottom of the filter pipe and enters the sedimentation pipe, and is finally discharged into the municipal drainage system through the drainage pipe. Since the sedimentation pipe is horizontally arranged and a plurality of water retaining blocks are provided in the sedimentation pipe, the flow rate of rainwater entering the sedimentation pipe is greatly reduced, so that small particles of sediment can slowly settle in the sedimentation pipe, and the settled sediment is stored in the collection box to prevent small particles of sediment from entering the municipal drainage system. The problem of the inability of the existing device to filter small particles of soil and gravel is avoided as much as possible, resulting in gravel and soil still flowing into the municipal drainage system with rainwater and settling and silting in the drainage system, which is easy to cause blockage of the municipal drainage system after a long time.

[0011] Optionally, the filtering structure is a first filter screen embedded in the inner cavity at the top end of the water filter pipe, the first filter screen is arranged obliquely, and the peripheral side of the first filter screen is fixedly connected to the inner wall of the water filter pipe.

[0012] By adopting the above technical solution, a first filter is set to filter large particles of impurities in rainwater. The first filter is tilted so that the large particles of impurities can slide along the first filter under the impact of rainwater and its own gravity and be collected in the storage component, thereby avoiding the blockage of the first filter by large particles of impurities, which may lead to poor drainage of the filter pipe.

[0013] Optionally, the storage component is a sewage storage pipe fixedly connected to the outer wall of one side of the water filter pipe connected to the lower end of the first filter screen, the bottom end of the sewage storage pipe is inclined downward, and the end of the sewage storage pipe away from the water filter pipe is screwed with a screw cap.

[0014] By adopting the above technical solution, a sewage storage pipe is provided for storing large particles of impurities, and a screw cap is screwed on one end of the sewage storage pipe away from the water filter pipe. When a large amount of impurities are collected in the sewage storage pipe, the user can screw the screw cap to open it, thereby discharging the impurities collected in the sewage storage pipe, making it convenient for the user to clean the impurities in the sewage storage pipe.

[0015] Optionally, the drain assembly includes a return pipe arranged below the sewage storage pipe, both ends of the return pipe are respectively connected to the sewage storage pipe and the inner cavity of the filter pipe, and a second filter is fixedly connected to the inner cavity of the connecting end of the return pipe and the sewage storage pipe.

[0016] By adopting the above technical scheme, a return pipe is provided to return the rainwater that enters the inner cavity of the sewage storage pipe together with impurities to the inner cavity at the bottom end of the filter pipe, and a second filter screen is provided to filter the returned rainwater. A right-angle block is provided on the side of the return pipe and the sewage storage pipe close to the filter pipe. The two right-angle sides of the right-angle block are welded to the return pipe and the sewage storage pipe respectively, and the hypotenuse of the right-angle block is welded to the side wall of the filter pipe, so as to reinforce the return pipe and the sewage storage pipe.

[0017] Optionally, one end of the sedimentation tube is sealed, and an elbow joint is provided between the open end of the sedimentation tube and the bottom end of the water filter tube, and the open end of the sedimentation tube is connected to the bottom end of the water filter tube through the elbow joint.

[0018] By adopting the above technical solution, a bend pipe joint is provided to connect the open end of the sedimentation pipe with the bottom end of the filter pipe, so that rainwater after preliminary filtration can flow into the sedimentation pipe for sedimentation.

[0019] Optionally, the collecting box is in a rectangular box-shaped structure, a magnetic ring in an annular structure is fixedly connected to the top of the collecting box, and the collecting box is magnetically connected to the inner wall of the through hole opened at the bottom of the sedimentation tube through the magnetic ring.
