Novel large and small rainwater diversion well for sponge city

Abstract

The invention discloses a novel large and small rainwater diversion well for a sponge city. The novel large and small rainwater diversion well comprises a well lid and a water storage pipeline communicated with a well body, wherein an annular mounting seat is fixedly mounted in the well body through threads, two groove bodies are formed in the inner wall of the annular mounting seat, and a flow guide cylinder is fixedly mounted on the lower surface of the annular mounting seat; and a floating block is mounted in the flow guide cylinder through a sliding structure, a water outlet hole matched with the water storage pipeline is formed in the flow guide cylinder, two sealing rings matched with the water storage pipeline are further fixedly mounted on the flow guide cylinder, and the sealing rings are located on two sides of the water storage pipeline. The novel large and small rainwater diversion well has the advantages that by means of matched use of a water collecting seat, a magnetic block I and a magnetic block II, the floating block can move downwards to restore to the initial position to shield the water storage pipeline after the water collecting seat is filled with rainwater in heavy rainy weather or continuous long-time light rainy weather, and large damage caused by the fact that too much rainwater is conveyed to a grass planting ditch through the water storage pipeline is avoided.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to a new type of large and small rainwater diversion wells for sponge cities. Background technique [0002] Water wells are an important part of the construction of sponge cities. Today's water wells have added a diversion function. In light rainy weather, rainwater can be stored and directly used to irrigate the corresponding plants, which has certain positive benefits. Excessive rain will lead to excessive water in planting parts, which will have a certain impact on the normal production of plants; [0003] After searching, the Chinese authorized utility model patent with the patent number CN207660076U discloses a new type of large and small rainwater diversion well for sponge cities. In the circle, and press the sewage intercepting hanging basket and the guide tube, the guide tube is fixedly arranged on the upper end of the well body. [0004] This diversion well has the ...

AI Technical Summary

Problems solved by technology

[0004] This diversion well has the following obvious shortcomings: in heavy rain or continuous light rain, a large amount of rainwater will be transported and irrigated the plants, and most of the plants are planted outdoors. The plant itself and the planting soil have absorbed a lot of water. At this time, the rainwater transported through the water storage pipe will cause too much water, which will easily cause the leaves of the plants to turn yellow or directly wash away part of the planting soil.
