Sponge city rainwater purification device

Abstract

The invention relates to the technical field of rainwater purification, and discloses a sponge city rainwater purification device which comprises a filtering bin, an inclined groove is formed in the outer surface of the filtering bin, a filtering device is fixedly installed in the inclined groove, and blocking devices are fixedly installed at the positions, located above the filtering device, in the filtering bin. The water depth in the inner cavity of the floating bin is gradually increased and gradually submerges the side floating block, at the moment, the side floating block gradually moves in the vertical upward direction under the action of buoyancy, at the moment, a traction rope II is fixedly installed on one side of a scraper, and the bottom of the side floating block is fixedly connected with one end of the traction rope II; a side floating block gradually pulls a scraping plate in the floating process, a blocking device is in an open state, at the moment, a certain amount of accumulated water exists at the top of the blocking device, and the accumulated water directly scours the top of a filtering device to a certain degree, so that the problem of blockage caused by too many impurities at the top of the filtering device is solved; and the stability of the device is further improved.

Description

Technical field [0001] The present invention relates to the field of rainwater purification technology, specifically a sponge city rainwater purification device. Background [0002] With the progress of urbanization, the urban environmental construction is also gradually valued by people, in recent years put forward a water resources management strategy and method, is a new generation of urban stormwater management concept, known as sponge city, refers to the city can be like a sponge, in adapting to environmental changes and responding to natural disasters caused by rainwater and other aspects of good resilience, is one of the construction goals of today's cities. [0003] In the construction process of sponge city, it is necessary to consider the collection, treatment and discharge of rainwater in all aspects, for example, in the treatment of rainwater, it is necessary to filter the debris in the rainwater, to avoid rainwater carrying a large number of food residues or animal c...
