Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rainwater treatment, in particular to a sponge city abandoned flow type rainwater recycling system. BACKGROUND

[0002] The sponge city refers to the city that can be like a sponge in terms of adaptation to environmental changes and response to natural disasters, etc., and has good "elasticity" in terms of water absorption, water storage, water penetration, water purification, water release and utilization when needed. The sponge city construction should follow the principles of ecological priority, etc., and combine natural ways with artificial measures to maximize the storage, penetration and purification of rainwater in the urban area under the premise of ensuring the safety of urban drainage and flood control, and promote the utilization of rainwater resources and ecological environment protection.

[0003] In the rainwater collection and utilization system of the sponge city, the abandoned flow of rainwater is crucial, because the initial rainwater runoff often contains impurities such as bird droppings, paper scraps, leaves, etc. If it is allowed to freely enter the rainwater well and water storage tank, not only will it increase the working strength of the filter, causing the filter to be blocked, but also after a long time of operation, the impurities will be deposited at the bottom of the pool, which is difficult to clean in the later period, and eventually will cause the entire system to be paralyzed, so the initial rainwater needs to use the abandoned flow device to abandon the initial rainwater containing more impurities, and collect and utilize the relatively clean rainwater in the later period.

[0004] In the existing rainwater abandoned flow device, in order to filter the initial rainwater, a filter screen is arranged to intercept the impurities in the initial rainwater, but the filter screen is easily blocked by impurities, thereby reducing the rainwater filtration effect. SUMMARY

[0005] In order to improve the rainwater filtration effect, the present application provides a sponge city abandoned flow type rainwater recycling system.

[0006] The sponge city abandoned flow type rainwater recycling system provided by the present application adopts the following technical scheme:

[0014] By adopting the technical scheme, when the top plate moves, the control block moves along the control groove, so that when the top plate moves out of the avoiding groove, the top plate drives the sealing plate to close the opening of the sinking box.

[0015] Optionally, two sealing plates are arranged in the sinking box.

[0016] By adopting the technical scheme, when the opening of the sinking box is exposed, the sealing plate is located in the sliding cavity, compared with one sealing plate, when two sealing plates move, the sliding distance of one sealing plate is short, and the part entering the sliding cavity is less, so that the interference of the receiving cavity to the filter hole on the filter plate is reduced, and the filtering effect of the filter plate is improved.

[0022] By adopting the above technical scheme, if there are a large amount of impurities in the rainwater, when the rainwater passes through the main water inlet pipe, the impurities in the rainwater will block the infrared light emitted by the infrared emitter, so that the infrared receiver cannot receive the infrared signal emitted by the infrared emitter opposite to it, at this time, the electromagnetic valve on the first shunt pipe is controlled to be opened, and the electromagnetic valve on the second shunt pipe is controlled to be closed; when the rainwater has no impurities or only contains a small amount of fine impurities, the infrared receiver can receive the infrared signal, at this time, the electromagnetic valve on the first shunt pipe is controlled to be closed, and the electromagnetic valve on the second shunt pipe is controlled to be opened, thereby realizing the shunting of the initial rainwater.

[0026] 3. If there are a large number of impurities in the rainwater, when the rainwater passes through the main water inlet pipe, the impurities in the rainwater will block the infrared light emitted by the infrared generator, so that the infrared receiver cannot receive the infrared signal emitted by the infrared emitter opposite to it. At this time, the electromagnetic valve on the first shunt pipe is opened, and the electromagnetic valve on the second shunt pipe is closed. When the rainwater has no impurities or only contains a small amount of fine impurities, the infrared receiver can receive the infrared signal. At this time, the electromagnetic valve on the first shunt pipe is closed, and the electromagnetic valve on the second shunt pipe is opened, so as to realize the diversion of the initial rainwater.
