Recoil intercepting rainwater recovery device

Abstract

The invention relates to a recoil intercepting rainwater recovery device. The device comprises a water collecting cylinder, a water pump, a slag discharging device, a water storage tank and a controlsystem, the water collecting cylinder and a rainwater collecting water inlet pipe communicate, an inner cavity of the slag discharging device communicates with the bottom of the water collecting cylinder through a first sewage disposal pipe, the slag discharging device is provided with a second sewage disposal pipe, the water outlet end of the first sewage disposal pipe and the water inlet end ofthe second sewage disposal pipe are provided with intercepting plates, the water pump is mounted in the water collecting cylinder, a water outlet of the water pump is connected with one end of a recoil pipe, the other end of the recoil pipe extends into the inner cavity of the slag discharging device and can impact the intercepting plate through water pumping to close the first sewage disposal pipe and the second sewage disposal pipe, the slag discharging device and the water storage tank are connected through a clean water pipe, a liquidometer is arranged in the water collecting cylinder, isconnected with the control systems and controls running of the water pump through the control system, sufficient recycling of rainwater particularly rainwater during large rainfall can be ensured, sink sundries and impurities in the device can be subjected to automatic flow abandoning and discharging, and the influence of the sewage disposal on rainwater recycling efficiency can be reduced.

Description

technical field [0001] The invention belongs to the technical field of rainwater collection and utilization equipment, and in particular relates to a recoil interception rainwater reuse device. Background technique [0002] With the rapid development of urban economy, urban infrastructure construction is also accelerating development, coupled with the increasing urban population, the demand for water sources is becoming more and more urgent. The existing municipal construction generally does not involve the collection and utilization of rainwater, resulting in the loss and waste of rainwater. If the rainwater in rainy days can be collected for daily use, it will greatly reduce the municipal water burden. [0003] In the process of rainwater collection, heavy dirt and impurities will be mixed in the rainwater. It is necessary to solve the pollution problem in the collection device under the premise of ensuring the highest possible rainwater recovery efficiency, especially whe...

The existing municipal construction generally does not involve the collection and utilization of rainwater, resulting in the loss and waste of rainwater. If the rainwater in rainy days can be collected for daily use, this will greatly reduce the municipal water burden

[0003] In the process of rainwater collection, heavy dirt and impurities will be mixed in the rainwater. It is necessary to solve the pollution problem in the collection device under the premise of ensuring the highest possible rainwater recovery efficiency, especially when the rainwater is fully recovered when the rainfall is heavy. However, there is no corresponding product on the market that can solve such practical problems
