Rainwater runoff control apparatus

Abstract

The invention discloses an initial rainwater runoff control device, which comprises a controller, a runoff collection pipe and a rainwater collection hopper, wherein, an electromagnetic valve connected with the controller is arranged in the runoff collection pipe; the lower end of the rainwater collection hopper is provided with a first rainwater monitoring hopper and a second rainwater monitoring hopper; a first floating ball, a first water outlet, a first overflow port and a first water level probe are arranged in the first rainwater monitoring hopper; a second floating ball, a second wateroutlet, a second overflow port and a second water level probe are arranged in the second rainwater monitoring hopper; and the first water level probe and the second water level probe are respectivelyconnected with the controller. Compared with the prior art, the device adopts a microcomputer control technology and has a control principle different from other devices; the microcomputer control has good stability, high accuracy, convenient operation, practicability and safety, and has greatly improved environment adaptability compared with the prior device; in addition, a microcomputer has lower power, so the device is more environment-friendly and energy-saving.

Description

technical field [0001] The invention relates to an initial rainwater runoff control device, which is used for the collection and treatment of initial rainwater and the collection and reuse of clean rainwater in the later stage, so as to reduce the harm to the environment and improve the utilization efficiency of rainwater, belonging to the technical field of rainwater runoff control. Background technique [0002] A large number of studies at home and abroad have shown that the initial rainwater runoff on roads, bridge decks, and roofs is seriously polluted and environmentally harmful, while the later rainwater runoff is relatively clean and can be reused after simple treatment. , Different regions, different places, and different rainfall types will cause great differences. And the runoff that needs to be collected in different places and locations is different. For example, in the living quarters, it is necessary to discard the initial rainwater and collect the later rainwa...
