Embodiment 1

[0032] Such as Figure 1-6 , an environmentally friendly rainwater grate for intercepting and diverting initial rainwater, it includes a casing 1, an inner sleeve 2 is suspended and installed inside the casing 1 through an elastic connector, and a device for The interception cover plate 3 for retaining the initial rainwater, the inner cover plate 4 is arranged at the top center of the inner sleeve 2, the rainwater discharge pipe 6 is arranged at the bottom of the outer shell 1, and the initial rainwater interception pipe 5 is connected to the bottom of the outer shell 1. It can intercept and divert the initial rainwater, and finally discharge it to the sewage treatment plant through the sewage pipeline for treatment.

[0033] Further, the elastic connecting member adopts an elastic rope or a spring, and uses its own weight for adjustment and control.

[0034] Preferably, the initial elastic force of the elastic rope or spring is greater than the gravity of the inner sleeve 2,...

Embodiment 2

[0041] A method for using an environmentally friendly rainwater grate for intercepting and diverting initial rainwater, comprising the following steps:

[0042] Step 1, in the initial stage of rainfall, the initial rainwater gradually collects near the rainwater grate, and first enters the space between the inner sleeve 2 and the outer shell 1 of the rainwater grate through the intercepting cover plate 3;

[0043] Step 2, after the initial rainwater enters the rainwater grate, it is discharged to the municipal sewage pipe through the initial rainwater interception pipe 5;

[0044] Step 3, as the rainfall continues, the rainwater flow becomes larger and larger, and the rainwater enters the rainwater grate inner sleeve 2 over the interception cover plate 3; as the rainwater in the rainwater grate inner sleeve 2 becomes more and more, affected by its own gravity, the falling To the bottom of the rainwater grate shell, the initial rainwater interceptor gate 9 is controlled by the ...

Abstract

The invention discloses an environment-friendly rainwater grate. The grate comprises a shell, an inner sleeve is installed in the shell in a suspended mode through an elastic connecting piece, and a closure cover plate used for closure of the initial rainwater is arranged between the shell and the inner sleeve. An inner cover plate is arranged in the center of the top of the inner sleeve, a rainwater drainage pipe is arranged at the bottom of the shell, and the bottom of the shell is communicated with an initial rainwater intercepting pipe. Initial rainwater can be intercepted and shunted and finally discharged to a sewage treatment plant through a sewage pipeline to be treated.

Description

technical field [0001] The invention belongs to the field of rain drainage facilities, and specifically discloses an environment-friendly rainwater grate for intercepting and diverting initial rainwater and a use method thereof. Background technique [0002] There are many pollutants on the ground in the downtown area of ​​the city. In the early stage of rainfall, the rainwater dissolves a large amount of polluting gases in the air. After landing on the ground, because of washing the ground and roof, the initial rainwater contains a large amount of pollutants, and the pollution degree even exceeds that of ordinary cities. domestic sewage. If it is directly discharged into the river through the rainwater pipe, it will pollute the water environment. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the background technology, and propose an environmental protection rainwater grate and its use method for intercepting and d...
