Rainwater collection well

Abstract

The invention provides a rainwater collection well, and belongs to the technical field of fixed buildings. The invention solves the problem that the existing rainwater collection well is prone to be blocked and thereby is poor to drain. The rainwater collection well comprises a well pedestal, a shaft and a rainwater collection well loop, wherein one end of the shaft is connected with the well pedestal while the other end is connected with the rainwater collection well loop, a water inlet is formed in the rainwater collection well loop, at least one drain hole is formed in the well pedestal, the water inlet communicates with the drain hole, a mud settling cavity is arranged at the bottom of the well pedestal, the drain hole is positioned on the side part of the well pedestal and higher than the mud settling cavity, a cone-shaped filter is arranged on the rainwater collection well loop, first sieve meshes are distributed in the outer circumferential surface of the filter, second sieve meshes are distributed at the bottom part of the filter, the filter stretches into the well pedestal after passing through the shaft, and the bottom part of the filter is positioned in a range corresponding to the drain hole. The filter of the rainwater collection well takes the shape of a cone, so that the gap between the filter and the rainwater collection well is gradually increased from the top down, rainwater flows down from the gap therebetween, and thereby drainage is smoother.

Description

technical field

[0001] The invention belongs to the technical field of fixed buildings, and relates to a rainwater collection system, in particular to a rainwater collection well. Background technique

[0002] The rainwater harvesting system is a system that collects rainwater during the rainfall process, and treats the collected rainwater to meet discharge or use standards. Rainwater collection wells are set up on roads, around buildings, etc., and rainwater can enter the pipe network of the rainwater collection system through the rainwater collection wells for subsequent processing of the collected rainwater.

[0003] Existing rainwater collection wells, for example, a surface rainwater storage and seepage device disclosed in Chinese patent [Application No. 201410049040.5; Publication No. CN103866841A], includes a well cover, a grid anti-drop basket, a flood storage infiltration area and a sinking area arranged sequentially from top to bottom. Mud area; there are penetrat...
