Multistage filtration rainwater collecting well device

Abstract

The invention provides a multistage filtration rainwater collecting well device. The multistage filtration rainwater collecting well device comprises a water taking pipe and a water pump; a rainwatercollecting cover is of an opening-closing structure, a filtration leak net is located in the rainwater collecting cover, and the rainwater collecting cover is mounted at the top of a rainwater collecting pipe; two well covers are mounted at the tops of the rainwater collecting pipe and the water taking pipe correspondingly; and a filer element shell is located in the rainwater collecting pipe, andthe bottom of the rainwater collecting pipe communicates with the top of a water storage tank. Waste materials contained in rainwater are intercepted and filtered advantageously, and the situations that the waste materials flow into the multistage filtration rainwater collecting well device along with rainwater, the interior of the multistage filtration rainwater collecting well device is blocked, and the water storage effect of the multistage filtration rainwater collecting well device is affected are avoided; by matching with the use of the filtration leak net, small particle impurities contained in rainwater can be intercepted and filtered, thus the small particle impurities are attached into the filtration leak net, the content of visible impurities in the rainwater is decreased, andthe situation that the number of the impurities in the rainwater is excessively large, and consequently the quality of a water body in the multistage filtration rainwater collecting well device is affected is avoided.

Description

technical field [0001] The invention belongs to the technical field of rainwater collection, and more specifically relates to a rainwater collection well device for multi-stage filtration. Background technique [0002] With the development of urban greening, the amount of water used for urban greening is gradually increasing. For cities with a shortage of water resources, the huge water consumption is likely to cause a burden on the urban water supply. It is collected and stored so that the green plants can be watered in seasons when rainfall is scarce, so as to reduce the consumption of water resources. [0003] The inventors found that there are existing similar rainwater collection devices, such as a garden rainwater collection device mentioned in patent application number CN201721468904.2. A garden rainwater collection device, including a plurality of rainwater collection mechanisms embedded on the ground and connected to each other, each of the rainwater collection mec...

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a rainwater collection well device with multi-stage filtration to solve the problem that the existing similar rainwater collection devices have poor interception effect on the garbage contained in the rainwater, and the garbage in the rainwater is easy to flow into the device Blocking the inside of the device will affect the rainwater circulation effect inside the device, and the effect of adsorption and filtration of a large number of impurity particles contained in the rainwater is poor, which will easily affect the quality of rainwater inside the device.
