Description

Hydraulic self-cleaning rainwater storage tank

Technical Field

The utility model belongs to the technical field of municipal works, concretely relates to water conservancy automatically cleaning rainwater regulation pond.

Background

Currently, stormwater storage ponds are a common structure in water storage systems for collecting contaminated stormwater beyond the drainage capacity of the downstream pipelines. The inlet water of the rainwater storage tank often contains a large amount of pollutants, dissolved and suspended small-particle pollutants can be discharged into a downstream sewage treatment plant for treatment gradually after the rainfall stops, and the pollutants are easy to convey through pipelines. However, the garbage and the large-volume solid pollutants in the rainwater are one of the pollutants which are difficult to transport and treat, and the pollutants can be deposited in the storage tank and difficult to clean, and are difficult to convey to a downstream sewage treatment plant through a pipeline.

Therefore, the rainwater storage pond generally intercepts garbage and large-volume pollutants by arranging the grating, and the grating is usually required to be continuously cleaned by mechanical facilities for ensuring that the grating can continuously run without being blocked, so that the equipment foundation investment is increased, and the operation and maintenance cost is increased.

Disclosure of Invention

In order to overcome the defect that above-mentioned prior art exists, the utility model aims to provide a water conservancy automatically cleaning rainwater regulation pond can be according to the volume of damming of upstream water volume size regulation, when the upstream water volume is big, can reduce the volume of damming automatically and reduce the quality of water impact to low reaches sewage treatment plant.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a hydraulic self-cleaning rainwater storage tank comprises a tank cavity 7 and a storage hopper 3 arranged on one side of the tank cavity 7, wherein an upper cover 5 is arranged on one side, close to the storage hopper 3, of the top end of the tank cavity 7, a water inlet pipe 8 is arranged on one side, far away from the storage hopper 3, of the upper cover 5, and a transverse roller grid 9 is horizontally arranged below the water inlet pipe 8; go up to be provided with connecting rod 6 in the uncap 5, the bottom swivelling joint of connecting rod 6 has the hook end 10 of clearance grid 1, and the top of clearance grid 1 is connected through pivot 4 with storage hopper 3.

The top end of the connecting rod 6 extends out of the upper cover 5.

The storage hopper 3 is equipped with ejection of compact swash plate 2 near pond chamber 7 one side, and pivot 4 sets up in ejection of compact swash plate 2's top.

The upper cover 5 is vertically deviated from the roller grill 9.

The drum grill 9 rotates clockwise or counterclockwise according to the flow direction of the water.

Said hook end 10 is in contact with the drum grate 9.

The beneficial effects of the utility model reside in that:

1. the potential energy of rainwater falling automatically is converted into the kinetic energy of the rotation of the roller grid 9, so that the energy is saved and the efficiency is high.

2. The roller grille 9 deviates from the vertical direction of the upper cover 5, so that the roller grille 9 rotates clockwise or anticlockwise, and the structure is reasonable.

3. In the process of rotating the roller grille 9, the hook end 10 of the cleaning grille 1 automatically scrapes the garbage on the roller grille 9 and stores the garbage in the hook end 10 of the cleaning grille 1, and the connecting rod 6 can be lifted after the hook end 10 is full of the garbage, so that the garbage enters the storage hopper 3 along the discharge inclined plate 2; reasonable structure, no need of additional electric machinery, low cost and good effect.
