Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipes, in particular to an anti-clogging municipal engineering drainage pipe model. Background Art

[0002] In recent years, the weather has changed abnormally, especially in the summer rainy season, when heavy rains often occur. The drainage capacity of urban sewers is insufficient, and the rainwater is mixed with mud and other debris, so the drainage pipes are very easy to be blocked. However, traditional sewer pipes are directly connected together, and relevant staff need to detect the blockage location in sections and dismantle the pipes to remove the silt. This workload is large and the work efficiency is low. In an emergency, the city may be flooded due to the inability to remove the blockage in time, and in serious cases, it may cause casualties.

[0003] The prior art discloses the application number: CN 206667425 U. The device can automatically clean the location where the blockage will occur, but when the parts in the drain pipe are damaged, they cannot be replaced in time, resulting in a decrease in the drainage effect of the drain pipe. In addition, the sealing of the drain pipe is poor, and water leakage often occurs, which further reduces the service life of the drainage pipe and increases the probability of accidents. It cannot prevent large impurities from entering the pipe, increasing the risk of device damage. For this reason, we propose a model of anti-blocking municipal engineering drain pipes. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an anti-clogging municipal engineering drainage pipe model.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, a sealing strip is provided at the contact portion between the upper tube body and the lower tube body, and a strip-shaped matching groove is provided at the position of the upper tube body and the lower tube body corresponding to the sealing strip.

[0008] Preferably, a filter screen is provided at one end of the first tube body away from the second tube body, and a protrusion matching the first tube body is provided at a side of the filter screen close to the first tube body.

[0009] Preferably, a scraping plate is provided at the lower end of the annular sleeve and is in close contact with the inner wall of the first tube body, and the front end of the scraping plate is in an arc shape and is in close contact with the inner wall of the tube body.

[0010] Compared with the prior art, the utility model proposes an anti-clogging municipal engineering drainage pipe model, which has the following beneficial effects: when a blockage is detected in the pipe body, the driving motor drives the gear to rotate through the transmission shaft, and the gear drives the annular sleeve to rotate, thereby driving the scraper plate to clean the impurities in the pipe body in time and restore the drainage effect of the sewer pipe. The device is divided into two parts, upper and lower, and is fixed with bolts during installation, which improves the efficiency of disassembly and installation, and when the parts in the pipe body are damaged, the damaged parts can be replaced in time. The first pipe body is equipped with a filter screen, and large impurities cannot enter the pipe body, further ensuring the smooth drainage of the drain pipe. BRIEF DESCRIPTION OF THE DRAWINGS
