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 regulating device based on a sponge city concept and a running method, relates to the technical field of rainwater source emission reduction and water source protection, and discloses a method suitable for cleanly collecting roof rain and conserving groundwater. The roof rainwater source regulating device based on the sponge city concept comprises a flow abandoning system, a water storing system, a groundwater conserving system and a control system. When the device runs, a control unit receives signals of a liquid level switch and a sensor and controls the opening and closing state of an arc-shaped gate and a flow abandoning hole valve, and the aims of emission reduction and process control of an urban roof rainwater source are achieved. The roof rainwater source regulating device is ingenious in design and high in automation degree and can greatly avoid surface runoff flood peaks, weaken urban runoff pollution loads, save rainwater resources, conserve groundwater, easily relieve the drainage pressure of an urban pipe network, reduce the probability of floods and ensure life and property safety of people.

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...
