Background technique

The rainwater outlet refers to the facilities for collecting surface water in the pipeline drainage system, and the structure for collecting rainwater on the rainwater pipes or confluence pipes. The rainwater from roads, grasslands, and even the roofs of some buildings first enters the rainwater outlet through the grate, and then flows into the river or lake through the connecting pipe. The rainwater inlet is the entrance of rainwater into the city underground, an important facility for collecting ground rainwater, and the channel that sends the rainwater from the sky directly to the urban river and lake water system. It is the primary channel for materials to enter the water environment, which not only drains urban roads, but also replenishes urban water bodies.

At present, the rainwater outlet used in China is composed of a well body, a well bottom and a rainwater grate. The well body is located below the surface and is connected to the sewer pipe. A large number of solid particle pollutants and suspended pollutants enter rivers and lakes with rainwater inlets, causing water pollution; when rainwater is discharged into static water bodies such as lakes, it will cause sedimentation in the water body and shallow water level. It takes a lot of manpower and material resources to carry out dredging frequently; and because the concentration of solid particulate pollutants and suspended pollutants in the rainwater inlet is blocked, the water conveying capacity is reduced, and the garbage left after the rain will be soaked in the rainwater. Gradually rotten and emit odor, breeding mosquitoes and flies, polluting the environment.

Based on this, the utility model designs a multi-layer rainwater filtering device for water conservancy and municipal engineering to solve the above problems.

The driving paddle 8 is installed in the cylindrical sleeve 132. , the driving rod 9 is slidably matched with the wall-clearing frame 7 through the limit key 91 and is connected in rotation.

When it rains, the rainwater concentrates and enters the filter device 6 at the top. Since the baffle ring 4 is slidingly matched with the bottom of the filter device 6, the rainwater will be collected at the bottom of the filter device 6. Under the action, the elastic element 5 is pressed down and lowered. With the downward movement of the elastic element 5, the bottom of the filter device 6 is separated from the retaining ring 4, and the rainwater falls from the bottom of the filter device 6 into the filter device 6 of the next layer. The garbage is left in the filter device 6 and circulated in sequence, and the large, medium and small garbage in the rainwater is separated from the rainwater one by one. Under the action of water, it quickly gathers in the cylindrical sleeve 132, and then flows into the urban drainage;

When the water flow passes through the cylindrical sleeve 132, the driving paddle 8 rotates under the impact of the water flow, the driving paddle 8 drives the driving rod 9 to rotate, and the driving rod 9 drives the wall cleaning frame 7 to rotate through the limit key 91, and the wall cleaning frame 7 is opposite to the filter device. 6. The side walls are cleaned to prevent the garbage filtered in the rainwater from blocking the filter device 6. The impact of the water flow is used to drive the wall cleaning frame to rotate, complete the cleaning work, and save energy, and solve the problem that the existing sewer pipes are easily damaged. Clogging of garbage, leading to the problem of reduced water delivery capacity.

The filter device 6 includes a slip ring 61 slidably fitted with the mounting portion 11 , and a filter barrel 62 is fixedly connected to the inner wall of the slip ring 61 .
