AI Technical Summary
Because the height of traditional drains is lower than that of the road surface, it is easy for garbage and leaves to gather and block, affecting normal drainage.
A new municipal road drainage device was designed, including an upright drainage pipe, a cover plate, a through drain outlet, a central cylinder, a floating cavity filter plate and a floating cylinder. When the rainfall increases, the water in the floating cavity causes the float to float, driving the hollow filter plate to lift up, making it difficult for garbage and leaves to block, and the rainwater drains through the filter plate.
Effectively prevent garbage and leaves from blocking the drain outlet, ensuring normal drainage of rainwater, and accelerating drainage through the drainage hole, which to a certain extent inhibits the odor of the sewage discharge pipeline.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of road drainage devices, in particular to a novel municipal road drainage device. Background Art
[0002] In order to facilitate drainage, the height of traditional drain outlets is slightly lower than the road surface, which makes it easy for garbage and leaves to gather here and cause blockage, seriously affecting normal drainage. Utility Model Content
[0003] The technical problem to be solved by the utility model is: in order to overcome the above problems, a novel municipal road drainage device is provided, which solves the above problems.
[0004] The utility model solves the technical problem by adopting the following technical solutions:
[0005] A novel municipal road drainage device comprises an upright drainage pipe, the lower end of which is connected to a municipal sewage pipe, the upper end of which is flush with the road surface, a cover plate is installed on the upper end of the drainage pipe, a plurality of through drainage ports are arranged at intervals on the cover plate, a central cylinder is fixedly arranged in the drainage pipe, a hollow filter plate is arranged to slide up and down in the middle of the cover plate, and a float is fixedly connected to the lower end of the hollow filter plate.
[0006] Preferably, the central cylinder has a floating cavity open upward, and water added to the floating cavity will cause the floating cylinder to float, thereby lifting the hollow filter plate, wherein a hollow cavity is provided in the hollow filter plate and a plurality of filter holes are provided through the front and back.
[0007] Preferably, a plurality of drainage channels are provided in an annular shape on the outer side wall of the central tube for normal drainage in non-rainstorm conditions.
[0008] Preferably, a plurality of drainage holes are provided at intervals in the middle of the central tube so as to enable the buoy to float after rainwater flows into the float cavity in a rainstorm environment, thereby accelerating the drainage of water through the drainage holes.
[0009] Preferably, the upper end of the central tube is provided with an outward inclined surface.
[0010] Preferably, when the buoy is not floating, the upper end surface of the hollow filter plate is flush with the upper end surface of the cover plate.
[0011] The advantages and positive effects of the utility model are as follows: after the rainfall increases, the excess rainwater is collected into the float cavity so that the float and the hollow filter plate float up, thereby making the hollow filter plate higher than the road surface, so that it is difficult for garbage, leaves and other objects to completely block the hollow filter plate with a certain height, and the rainwater is drained through the hollow filter plate that passes through, and the drainage is ensured by ensuring that the float remains floating until most of the water is discharged from the drainage hole, and because the drainage hole is usually pressed by the float and the flow area of the drainage channel is limited, the odor from the sewage pipe is suppressed to a certain extent. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0013] Figure 1 It is a structural schematic diagram of the utility model;
[0014] Figure 2 yes Figure 1 Schematic diagram of the top view of the middle drain pipe 11 and the cover plate 13. DETAILED DESCRIPTION
[0015] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.
[0016] The following is a further description of the embodiments of the present invention in conjunction with the accompanying drawings:
[0017] like Figure 1-2 As shown, a new municipal road drainage device described in the utility model includes an upright drainage pipe 11, the lower end of the drainage pipe 11 is connected to the municipal sewage pipe 10, the upper end of the drainage pipe 11 is flush with the road surface, a cover plate 13 is installed on the upper end cover of the drainage pipe 11, a plurality of through drainage ports 19 are arranged at intervals on the cover plate 13, a central cylinder 12 is fixedly provided in the drainage pipe 11, a hollow filter plate 18 is slidably provided in the middle of the cover plate 13, and a float 17 is fixedly connected to the lower end of the hollow filter plate 18.
[0018] Preferably, the central cylinder 12 has a floating cavity 16 which is open upwards. When water is added to the floating cavity 16, the floating cylinder 17 will float up, thereby lifting up the hollow filter plate 18. The hollow filter plate 18 has a hollow cavity therein and a plurality of filter holes extending through the front and back.
[0019] Preferably, a plurality of drainage channels 14 are provided in an annular shape on the outer wall of the central tube 12 for normal drainage in non-rainstorm conditions.
[0020] Preferably, a plurality of drainage holes 15 are provided at intervals in the middle of the middle tube 12 so as to enable the buoy 17 to float after rainwater flows into the float chamber 16 in a rainstorm environment, thereby accelerating the drainage of the drainage holes 15 .
[0021] Preferably, the upper end of the middle tube 12 is provided with an outward inclined surface.
[0022] Preferably, when the buoy 17 is not floating, the upper end surface of the hollow filter plate 18 is flush with the upper end surface of the cover plate 13 .
[0023] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
