Sewage-intercepting and flow-abandoning type rain collector capable of performing back flushing automatically

Abstract

The invention provides a sewage-intercepting and flow-abandoning type rain collector capable of performing back flushing automatically. The sewage-intercepting and flow-abandoning type rain collector comprises an automatic control system, a flow-abandoning sensor and a rain water before-collection treating and distributing device. The flow-abandoning sensor at least comprises a flow-abandoning regulating chamber and a photoelectric liquid level sensor installed in the flow-abandoning regulating chamber; the rain water before-collection treating and distributing device at least comprises a base and a rail water distributing treating pool installed on the base, and the rain water distributing treating pool sequentially comprises a potential-reduction adsorption cavity, a flow distribution cavity and a sediment collection cavity from top to bottom; and the automatic control system at least comprises a power source, a singlechip and a conductor. The rain water collector takes raininess and rainwater quality into accounts and simultaneously can regulate the flow abandon amount at the initial rainfall stage, and the abandoned rail water is discharged after treatment, so that the abandoned rain water can be prevented from polluting the underground water. The sewage-intercepting and flow-abandoning type rain collector can further perform automatic back flushing, is improved in using benefit, and simultaneously can convert the potential energy of the rain water into electric energy so as to supply power for the rain water collector.

Description

technical field [0001] The invention relates to a rain collector, in particular to a sewage interception and waste flow rain collector capable of automatic backwashing, which belongs to the field of rainwater collection. Background technique [0002] my country has a vast territory, with great climate differences, and the annual rainfall distribution is very uneven, generally decreasing from the annual average of 1600 ram in the southeast coast to less than 200 mm in the northwest inland. The area south of the Yangtze River has abundant rainfall, and the annual rainfall is above 1000mm. Most of the annual rainwater is mostly concentrated in summer, and it is often heavy rain or rainstorm, resulting in a large amount of water accumulation in a very short period of time. Therefore, the roof of the building needs to be equipped with a rainwater drainage system, and the roof, The rainwater on the road surface should be drained and utilized in time, otherwise it will cause flood...

AI Technical Summary

Problems solved by technology

At present, the existing rainwater harvesting devices at home and abroad cannot flexibly adjust the discarded flow of initial rainfall according to the actual situation, and do not consider the relationship between rain intensity and rainwater quality

Moreover, the waste flow pool consumes a lot of energy, is large in size, and high in cost, resulting in zero or even negative benefits for rainwater collection.

At the same time, the direct discharge of abandoned rainwater has caused irreversible pollution to groundwater.
