Environment-friendly water collecting device used for urban landscaping distributed infiltrating irrigation

Abstract

The invention relates to an environment-friendly water collecting device used for urban landscaping distributed infiltrating irrigation. The environment-friendly water collecting device comprises a well body used for collecting rainwater and infiltrating irrigation pipes connected with the well body and buried underground. The well body comprises a water collecting well and an infiltrating irrigation well connected with the water collecting well. A grate is arranged at a water inlet of the water collecting well, and a filtering basket with filtering media is connected to the lower portion of the grate. The infiltrating irrigation pipes are connected to the infiltrating irrigation well. Each infiltrating irrigation pipe comprises a pipe body, a water outlet channel is formed in each pipe body in the length direction, an expanding groove with an opening facing the outside of each pipe body is formed in the portion, along one side of the corresponding water outlet channel, of the corresponding pipe body, each expanding groove is only provided with the corresponding opening facing the outside of the corresponding pipe body, a sealing edge capable of being attached to the outer wall of the corresponding expanding groove to close the corresponding water outlet channel accordingly is formed on the other side of the corresponding water outlet channel, an expanding body which can expand after absorbing water to enable the outer wall of the corresponding expanding groove to be attached to the corresponding sealing edge accordingly is arranged in the corresponding expanding groove, and a plurality of elastic reset structures are arranged at an opening of each expanding groove. By means of the environment-friendly water collecting device, rainwater can be collected to infiltrate urban landscaping, landscaping water can be saved, the structure is simple, and use is convenient.

Description

technical field [0001] The invention relates to a seepage irrigation device, in particular to an environment-friendly water collection device for distributed seepage irrigation in urban greening. Background technique [0002] Urban greening facilities can improve the quality of urban natural ecology and are conducive to environmental protection. At the same time, they can increase the aesthetic effect of urban landscapes, increase urban economic benefits, help urban disaster prevention, and purify air pollution. It is an important goal of modern urban construction and management to increase the coverage rate of urban greening and make it exert greater ecological and landscape benefits. On the other hand, urban water resources are increasingly tense, while rainwater resources are not well utilized. How to collect and make good use of rainwater runoff from urban pavements, and meet the water demand for urban greening without increasing the pressure on municipal water resource...

AI Technical Summary

Problems solved by technology

[0004] However, in order to avoid excessive irrigation, the existing infiltration irrigation pipes are equipped with valves to control the opening and closing of the infiltration irrigation pipes, and a soil moisture detector needs to be installed to monitor the soil moisture in real time. The use cost is high, but the soil moisture detector cannot The soil moisture is evenly detected, and the water outlet area of ​​the infiltration irrigation pipe is large, so it is impossible to irrigate a specific location, resulting in poor irrigation effect

In addition, the filter device of the collection well is generally provided with a grate at the water inlet of the collection well, but the grate can only filter larger impurities, and smaller impurities such as sediment will still enter the water collection well, resulting in blockage of the seepage irrigation pipe
