[0012] Preferably, a plurality of electric drive wheels are provided at the bottom of the mobile box.

[0013] Preferably, the side walls of the movable box are provided with a plurality of guide rollers.

[0014] A municipal pipeline desilting method comprises the following steps:

[0015] The mobile box is placed into the pipeline through the inspection well so that the end cleaning plate is in close contact with the inner wall of the pipeline, and the other end of the municipal pipeline is temporarily blocked. Water is input into the pipeline through the pumping mechanism. When the water level in the pipeline reaches the predetermined position, the scraper rotates to hang down the silt on the inner wall of the pipeline. The stirring plate rotates to fully stir the silt scraped off by the scraper with the water in the pipeline to keep it in a suspended state to avoid re-deposition. At the same time, the pumping mechanism pumps the mixed liquid after cleaning to the outside to complete the entire pipeline cleaning.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] The present invention provides a municipal pipeline dredging device. When the municipal pipeline needs to be dredged, a mobile box or the like is placed into the pipeline through an inspection well so that an end face cleaning disk is closely attached to the inner wall of the pipeline, and the other end of the municipal pipeline is temporarily blocked. Water is pumped into the pipeline through a pumping mechanism, and a motor is started at the same time. The motor can drive the spur gear to rotate, thereby driving the first end face gear and the second end face gear meshed with the motor to rotate. When the first end face gear rotates, it can drive the scraper on the inner wall of the pipeline to drop the silt on the inner wall of the pipeline with the scraper on its peripheral side. When the second end face gear rotates, it can drive the stirring plate on the peripheral side to fully stir the silt scraped off by the scraper with the water in the pipeline to put it in a suspended state to avoid re-deposition. At the same time, it also helps to use the pumping mechanism to pump the mixed liquid cleaned to the ground for centralized treatment. The equipment can replace manual pipeline dredging, reduce the safety risk of workers entering the pipeline, and effectively solve the problems of low cleaning efficiency and high labor consumption when manually dredging the pipeline.

[0018] Furthermore, a clean water tank can be used to store water, which is then pumped into the first hollow shaft through a water pipe. In this way, when dredging the pipeline, the water ejected from the first hollow shaft can not only assist in cleaning the sludge that is firmly adhered to the pipeline between the scrapers on the first hollow shaft, but can also suspend the cleaned sludge in time. At the same time, it can also cooperate with the sludge suction mechanism to ensure that the water inside the pipeline is always in an ideal position, further improving the cleaning effect of the equipment on the pipeline.

[0019] Furthermore, the mud suction port of the mud suction mechanism is close to the stirring plate, so that the mixed mud suspended after being processed by the stirring plate can enter the mud delivery pipe through the mud suction pipe in time, and then enter the filter tank through the mud delivery pipe through the mud discharge pipe. The mud pump can provide power for this process. When the mixed mud enters the filter tank, the mud screen can separate the silt and water. The silt will remain on the mud screen, and the water will enter the clean water tank again through the mud screen, which can increase the water utilization efficiency and effectively save water resources. The silt on the mud screen is also easier to transport than the mixed mud.

[0020] Furthermore, the leakage holes on the scraper can prevent the scraped sludge from forming resistance to the rotation of the scraper when there is a lot of sludge in the pipeline, and the spirally arranged stirring plate can further enhance its ability to stir the sludge evenly in the water.

The first hollow shaft 507 is provided with a plurality of scrapers 509 in a circumferential array on the side away from the end of the protective shell 501. The scrapers 509 can scrape the sludge in the pipeline. The second hollow shaft 508 is provided with a plurality of stirring plates 510 in a circumferential array on the side close to the end of the scraper 509. The stirring plates 510 fully stir the sludge scraped off by the scrapers 509 with the water in the pipeline to keep it in a suspended state to avoid re-deposition. At the same time, it also helps to use the pumping mechanism 6 to pump the cleaned mixed liquid to the ground for centralized treatment.

[0028] like Figure 1 As shown, the pumping mechanism 6 includes a clean water tank 61, in which a water pump 62 is provided. Figure 3 and Figure 4As shown, the water pump 62 is connected to one end of a water pipe 63, and the other end of the water pipe 63 sequentially penetrates the moving box, the side wall of the end cleaning disk 4 away from the stirring plate 510, and the side wall of the protective shell 501 away from the stirring plate 510, and is rotatably connected to the end of the first hollow shaft 507 away from the scraper 509, and the water pipe 63 and the first hollow shaft 507 are connected, and a mud suction mechanism 64 is provided in the clean water tank 61. The clean water tank 61 can be used to store water, and the water pump 62 is used to send water into the first hollow shaft 507 through the water pipe 63. In this way, when desilting the pipeline, the water ejected from the first hollow shaft 507 can not only assist in cleaning the sludge firmly adhered to the pipeline between the scraper 509 on the first hollow shaft 507, but also suspend the cleaned sludge in time, and can also cooperate with the mud suction mechanism 64 to ensure that the water inside the pipeline is always in an ideal position, further improving the cleaning effect of the equipment on the pipeline.

When the first end face gear 503 rotates, it can drive the scraper 509 on its peripheral side to hang down the silt on the inner wall of the pipeline, and the second end face gear 504 When rotating, the stirring plate 510 on its side can fully stir the sludge scraped off by the scraper 509 with the water in the pipeline to make it suspended to avoid re-deposition. At the same time, the mud pump 643 in the pumping mechanism 6 is started to pump the cleaned mixed liquid into the filter tank 645 in the clean water tank 61. When the mixed mud enters the filter tank 645, the mud screen 646 can separate the sludge and water, and the sludge remaining on the mud screen 646 is transported and processed, and the water will enter the clean water tank 61 again through the mud screen 646 to be used continuously. After cleaning a section of the pipeline, the electric drive wheel 2 is used to move the equipment until the entire pipeline is cleaned.
