Technical Field

[0001] The utility model belongs to the technical field of pipe network dredging devices, and specifically relates to an adjustable municipal pipe network dredging device. Background Technique

[0002] The municipal pipe network is an urban infrastructure construction composed of multiple pipe network systems, covering multiple aspects such as roads, drainage, water supply, gas, heat, and electricity, and can mainly achieve multiple functions such as water supply, drainage, and gas supply.

[0003] During the long-term use of the municipal pipe network, a large amount of silt, garbage, sand and other sundries are easily accumulated inside, resulting in pipeline blockage, poor water flow, etc. The municipal pipe network dredging device can clean the deposits in the pipe network to restore the drainage and other functions of the pipe network.

[0004] When cleaning the municipal pipe network, it is common to scrape the inner wall of the municipal pipe network by rotating the cutter head. However, the inner diameter specifications of some municipal pipes are not consistent. For pipes with a smaller inner diameter, the rotating cutter head may not be able to effectively enter, and for pipes with a larger inner diameter, the cleaning range of the rotating cutter head may be limited, requiring repeated operations, thus increasing the cleaning time and labor cost.

[0008] Preferably, a filter screen is installed at one end of the first water pipe; a first scraper is fixedly connected to the inside of one end of the second water pipe through a connecting frame, and the cleaning end of the first scraper contacts the surface of the filter screen.

[0009] Preferably, a mounting bracket is mounted on the first telescopic rod, and a protective bracket is fixedly connected to the middle of one end of the mounting bracket via a spring column.

When the liquid is sprayed out through the high-pressure nozzle rack, the central nozzle will directly spray onto the scraping rack. At this time, the liquid will generate a certain thrust on the scraping rack. The thrust is transmitted to the second telescopic rod through the connecting rod, and then the scraping rack is pushed to move slightly through the second telescopic rod to automatically adjust the degree of fit between the scraping rack and the inner wall of the pipe, so that the scraping rack can fit more closely to the uneven or dirt-accumulated places on the inner wall of the pipe, so as to adapt to the changes in the inner wall of the pipe in real time, reduce the cleaning dead corners caused by loose fit, and improve the cleaning effect.
