Description

Technical Field

[0001] The utility model relates to the technical field of rainwater collection and treatment, and in particular to a rainwater collection and treatment system for a sponge city. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept, which means that the city can adapt to environmental changes and deal with natural disasters caused by rainwater like a sponge, and has good elasticity. It can also be called a "water-elastic city". The internationally accepted term is "low-impact development rainwater system construction", which absorbs, stores, infiltrates and purifies water when it rains, and releases and utilizes the stored water when needed, so as to realize the free migration of rainwater in the city.

[0003] For rainwater collection and treatment, existing technologies include:

[0004] Chinese patent publication number CN214415757U discloses a rainwater collection and treatment system for sponge cities, including a downpipe for receiving rainwater and a filter installed in the downpipe for filtering rainwater, and also includes a mounting mechanism movably installed in the downpipe, the downpipe is provided with a accommodating groove for accommodating the mounting mechanism, and the mounting mechanism is used for the filter to be detachably installed in the downpipe.

[0005] It can be seen from this that when collecting rainwater, a filter is needed to filter the large particles of impurities in the rainwater. After the rainwater is filtered, a large amount of impurities will accumulate on the surface of the filter and need to be cleaned. The prior art installs a snap assembly on the outer surface of the filter to facilitate disassembly and cleaning of the filter. However, after the filter filters the rainwater, impurities such as leaves will accumulate on the surface, which is not convenient for taking the filter to clean. In addition, the surface of the filter is more dirty, and it is not convenient for staff to take it manually. Therefore, a rainwater collection and treatment device that can easily clean the rainwater collection filter is needed.

[0006] In view of this, the utility model provides a rainwater collection and treatment system for a sponge city. Utility Model Content

[0022] Working process:

[0023] When filtering rainwater, rainwater naturally flows to the cover plate in the depression, and flows from the cover plate into the water storage tank inside the collection tank. Impurities in the rainwater are filtered through the filter screens on both sides of the water storage tank, and the impurities behind the filter screens are collected by the collection box placed at the bottom of the inner wall of the water storage tank.

[0024] When cleaning the impurities collected in the collection box, open the cover to allow the threaded hole on the top of the lifting column to leak out, use an adapted threaded column to rotate and install it into the lifting column through the threaded hole, and the staff pulls the lifting column connected to the threaded column to drive the collection box to rise. When the collection box rises, the scraper scrapes off the impurities stuck to the filter screen, and finally pulls out the collection box to clean the impurities accumulated in the collection box.
