Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings.

[0043] Such as Figure 1-Figure 4 As shown, the roof rainwater source control device based on the sponge city concept of the present invention includes a control system 1 , a waste flow system 2 , a water storage system 3 and a groundwater conservation system 4 .

[0044] Among them, the control system 1 includes a lock chamber 11, an arc gate 12, a hinge seat 13, a hoist 14 and a control unit 15. The lock chamber 11 is vertically arranged and fixed on the outer wall of the building. The upper and lower walls of the lock chamber 11 are respectively A circular water inlet 111 and a circular water outlet 112 are provided, and a rectangular water outlet 113 is provided on the right side wall.

[0045] The abandonment system 2 includes an initial rainwater abandonment box 21, a float level switch 22, a light sensor 23 and an abandonment hole 24. The initial rainwater aban...

Abstract

The invention discloses a roof rainwater source control device and an operating method based on the concept of a sponge city, relates to the technical fields of rainwater source reduction and water resource protection, and is a method suitable for cleanly collecting roof rain and conserving groundwater. The roof rainwater source control device based on the sponge city concept of the present invention includes a waste flow system, a water storage system, a groundwater conservation system and a control system. The opening and closing state of the orifice valve realizes the purpose of reducing the source of urban roof rainwater and controlling the process. The invention is ingenious in design and high in automation, can greatly stagger surface runoff flood peaks, reduce urban runoff pollution load, save rainwater resources, and conserve groundwater, which is conducive to alleviating the drainage pressure of urban pipe networks, reducing the probability of floods, and protecting people's lives and property Safety.

Description

technical field [0001] The invention relates to the technical fields of rainwater source reduction and water resource protection, in particular to a roof rainwater source control device and an operating method based on the sponge city concept. Background technique [0002] The global shortage of water resources is related to food security, ecological security, environmental security, economic security, and even life security. It is a major problem that needs to be solved urgently. According to the official statistics of the Ministry of Water Resources, my country's current shortage of water resources is very serious. The per capita amount of fresh water resources is only 2,200 cubic meters, which is only a quarter of the world's average level. One of the most resource-poor countries. In recent years, every rainy season, cities around the world have taken turns to stage the scene of "city looking at the sea", causing serious flood disasters, casualties and property losses. I...
