Automatic rainwater discarding, collecting and washing device and operating method thereof

Abstract

The invention discloses an automatic rainwater discarding, collecting and washing device and an operating method thereof. The automatic rainwater discarding, collecting and washing device comprises a discarding, water-collecting and washing control cavity, a collected water filtering cavity, a discarding cavity, a collected rainwater inlet, a collected rainwater outlet, a discarded rainwater outlet, a discarding control hole, a collected rainwater through hole, a discarding cavity washing control hole, a valve body control plate, a collected rainwater partition plate, a discarded rainwater partition plate, a bottom plate, a water inlet end plate and a water outlet end plate top cover; the automatic rainwater discarding, collecting and washing device is cuboid-shaped; the vertical collected rainwater partition plate is arranged in an inner cavity of the automatic rainwater discarding, collecting and washing device, and is used for dividing the inner cavity of the automatic rainwater discarding, collecting and washing device into a left side cavity body and a right side cavity body; the volume of the left side cavity body is 1.5 to 3 times that of the right side cavity body. The automatic rainwater discarding, collecting and washing device is simple and convenient to process, small in size and low in production cost; the clean state of the whole device can be effectively ensured; and the normal operation of the device can be ensured all the time.

Description

technical field [0001] The invention belongs to the technical field of sponge cities, and in particular relates to an automatic rainwater waste collection and cleaning device and a working method thereof. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water for use when needed. [0003] During the initial rainfall, the first 2~5mm of rainwater is generally seriously polluted and the flow rate is relatively small. Rainwater dissolves a large amount of acid gases in the air, car exhaust, factory exhaust and other polluting gases, and generally contains a certain ...

AI Technical Summary

Problems solved by technology

[0006] The invention provides a simple initial rainwater single-chamber discarding tube. (1) The volume of most of the discarding devices is set to the volume of all the initial rainwater, which is too large, inconvenient to operate, and high in cost; (2) manual operation is used to discharge the initial rainwater The device is easy to fail due to operational problems; although the volume of the waste flow device equipped with an automatic switch is small, it has the disadvantages of complex structure and high cost, so as to achieve small size, low cost, and only one cavity can realize the whole process of rainwater collection and disposal.
