Description

Technical Field

[0001] The invention relates to the technical field of road drainage, and in particular to a rainwater outlet capable of intercepting initial rainwater and domestic sewage discharged on sunny days. Background Art

[0002] On urban roads, especially in old urban areas, the runoff generated at the beginning of the rain will wash the surface, forming relatively dirty initial rainwater. The direct discharge of this initial rainwater will have an impact on the environment. Traditional rainwater inlets do not have the function of intercepting initial rainwater. They collect surface rainwater from the beginning of the rain until the rain stops, which is not conducive to environmental protection. At the same time, in some old urban areas, there is often sewage discharge from restaurants and shops along the street. This part of domestic sewage directly enters the rainwater inlet. Traditional rainwater inlets have no interception capacity for this part of sewage, so it will also have an adverse impact on the environment. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a rainwater inlet with the function of intercepting initial rainwater and domestic sewage discharged on sunny days, which intercepts domestic sewage discharged on sunny days and part of the initial rainwater and sends them to a sewage treatment plant, thereby realizing the diversion of initial rainwater and domestic sewage discharged on sunny days from rainwater in the middle and late stages of rainfall.

[0004] The technical solution of the present invention is: a rainwater inlet capable of intercepting initial rainwater and domestic sewage discharged on sunny days, which internally comprises a rainwater inlet component and an opening and closing component for controlling the rotation of a baffle.

[0005] The rainwater inlet assembly comprises a sewage connecting pipe and a rainwater connecting pipe; the sewage connecting pipe and the rainwater connecting pipe are staggered in the same direction, and the bottom elevation of the rainwater connecting pipe is higher than the top elevation of the sewage connecting pipe.

[0006] The opening and closing assembly includes a rotating rod with a baffle, a connecting cross bar, a force transmission rod with a rainwater collection and emptying cup on the top, a spring, a starting limit block, and an ending limit block; the bottom of the rainwater collection and emptying cup is higher than the top of the rainwater connecting pipe; the force transmission rod and the connecting cross bar are hinged at a first fulcrum; one end of the connecting cross bar is hinged at a second fulcrum with the rotating rod; the other end of the connecting cross bar is connected to the spring, and the spring is vertically arranged along the side wall of the rainwater outlet, the upper end of the spring is fixed on the side wall of the rainwater outlet, and the other end can be stretched downward, and a starting limit block and an ending limit block are respectively arranged on the stretching path; a counterweight is arranged under the force transmission rod; the upper end mounting point of the rotating rod is located directly above the sewage connecting pipe, and the rotating rod can rotate around the upper end mounting point; a baffle is arranged at the lower end of the rotating rod, and the baffle can cover the sewage connecting pipe opening; when the moving end of the spring is in the starting limit block position, the baffle is away from the sewage connecting pipe; when the moving end of the spring is in the ending limit block position, the baffle completely covers the sewage connecting pipe.

[0007] Based on the above technical features: there is a mesh at the mouth of the rainwater collection and emptying cup.

[0008] Based on the above technical features: the wall of the rainwater collection and emptying cup has micropores.

[0009] Based on the above technical features: the bottom of the baffle is an arc with a circular mounting point at the upper end.

[0010] On sunny days, there is no water in the rainwater collection and emptying cup, the spring contracts and is in the starting limit block position, the baffle is in the open state, and the domestic sewage discharged on sunny days is discharged through the sewage connecting pipe.

[0011] At the beginning of rainfall, water begins to accumulate in the rainwater collection and draining cup. The increased weight stretches the spring, causing the baffle to rotate and partially blocking the sewage connecting pipe. The initial rainwater is still discharged from the sewage connecting pipe.

[0012] In the middle and late stages of rainfall, the rainwater collection and draining cup is filled with water, the spring is stretched to its maximum length and is at the end limit block position, the baffle completely covers the sewage connecting pipe, the sewage connecting pipe channel is closed, and the rainwater in the middle and late stages is discharged through the rainwater connecting pipe.

[0013] After the rainfall stops, the rainwater collected and in the air defense cup seeps out through the micropores and is drained, the spring contracts to the starting limit block position, and the baffle is fully opened.

[0014] Compared with the prior art, the present invention has the following beneficial effects: it can intercept the scattered domestic sewage discharged on the street on sunny days and enter the municipal sewage network, and can intercept part of the initial rainwater, reducing the impact on the environment, which is conducive to the separation of clean and dirty water in the urban drainage system.
