Intelligent sponge urban rainwater-collecting and recycling system and application thereof

Abstract

The invention discloses an intelligent sponge urban rainwater-collecting and recycling system and an application thereof. In the system, a water pump (13) is arranged in a water storage tank (27), wherein the water pump (13) is connected with an intelligent controller (5) through an external wire (3); the intelligent controller (5) is connected with a humidity sensor (1) embedded in a plant soil layer (6) through the external wire (3); a reversed filter layer (7) is arranged under the plant soil layer (6); a macadam blind ditch (9) and a water filtering channel (8) are arranged under the reversed filter layer (7); the water filtering channel (8) is communicated with the water storage tank (27); the water pump (13) is used for conveying irrigation water to the plant soil layer (6) through an irrigation water pipe (12). According to the invention, the water filtering channel is connected with the bottom of the water seepage position, so that the multiple functions, including seepage, storage, use, draining, and the like, are integrally combined with each other and the rainwater recycling system is further optimized. The water feeding and draining manners of the rainwater device are intelligently controlled, so that the automation purpose can be achieved.

Description

technical field [0001] The invention belongs to the technical field of intelligent engineering in municipal engineering, and in particular relates to an intelligent sponge city rainwater collection and reuse system and its application. Background technique [0002] my country is a country with relatively poor water resources and extremely uneven temporal and spatial distribution. The year-to-year variation of water resources is large, and the distribution of precipitation and runoff is concentrated in the summer months; successively abundant and successively dry years occur alternately, resulting in frequent drought disasters in some areas and prominent contradictions between supply and demand of water resources. The total amount of water resources in my country is more than 2.8 trillion m3, ranking sixth in the world, but the per capita water resources are only 2300 m3, about 1 / 4 of the world average level. 81% of the country's water resources are concentrated in the Yangt...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide an intelligent and automatic intelligent sponge city rainwater collection and reuse system and its application for the three aspects of storage, use and drainage of excess rainwater in sponge cities, so as to solve the difficulty in collecting excess rainwater in existing sponge cities problems, and save more irrigation water for urban greening
