Description

Technical Field

[0001] The utility model belongs to the technical field of sewer pipe dredging, and particularly relates to a sewer pipe dredging and silt cleaning device. Background Art

[0002] Blockage problems caused by silt deposition often occur in sewers. The adhesion and deposition of silt will affect the water flow of sewer pipes and have a non-negligible impact on the drainage system. To solve the above problems, a dredging and silt cleaning device is needed to regularly clean sewer pipes.

[0003] In the Chinese utility model patent with the publication number CN220814201U, a sewer silt cleaning device is disclosed. The horizontal pipe is driven to rotate by a forward and reverse motor, and then the hollow cone block and the front pipe can rotate. Moreover, the automatic walking mechanism can be driven to fit and walk along the inner wall of the pipe. When the fifth rotating shaft rotates, it can drive the fourth rotating shaft and the third rotating shaft to rotate. Then, the worm can drive the worm wheel to rotate, and the second rotating shaft can drive the first rotating shaft to rotate to complete the fitting of the scraper with the inner wall of the pipe. During the overall walking process, a high-pressure water source is connected by a rubber hose, and the overflow holes spray water onto the inner wall of the pipe. The rotating scraper can loosen the silt, making it easy to dilute and flow out. This device is suitable for cleaning various sewer pipes and has market promotion value. However, when the first drive shaft rotates, through the cooperation of the bevel gear set, the rotation directions of the left and right two second drive shafts at the same height position are opposite to each other. Therefore, it will cause a non-negligible serious interference to the normal walking of the device, affecting the normal operation of the device. Moreover, the extension length of each group of automatic walking mechanisms needs to be manually adjusted, resulting in inconvenient operation.

[0039] The working principle of the present utility model is as follows:

[0040] During use, first select an external hose 5 with an appropriate length and connect the end away from the rotary joint 4 to an external water pump. Then select a wire with an appropriate length to energize the servo motor 12. Subsequently, the staff adjusts the extending length of the movable rod 35 from the fixed rod 33 according to the inner diameter of the sewer pipe to be dredged until the scraping plate 36 can contact the inner wall of the sewer pipe, and then tighten the first bolt 34 to position the movable rod 35 and the scraping plate 36.

During the rotation adjustment process of the traveling component 8, the first gear 83 and the third gear 87 on the outer side of the same connecting rod 84 can always be engaged with the second gear 85, which is convenient for the subsequent stable movement of the device.

[0041] After the adjustment is completed, the device can be placed into the sewer pipe. At this time, both the scraping plate 36 and the traveling wheels 88 are in contact with the inner wall of the pipe. When the servo motor 12 is started to control the second conical tooth 13 to rotate rapidly, the conveying pipe 2 and the dredging component 3 can be driven to rotate rapidly through the first conical tooth 6. The external water source can be conveyed to the hollow disc 31 through the external hose 5, the rotary joint 4 and the conveying pipe 2, and then sprayed onto the inner wall of the pipe by multiple high-pressure nozzles 32, which can wash the sludge on the inner wall of the sewer pipe. The rotating scraping plate 36 can scrape the stubborn sludge on the inner wall of the pipe, resulting in more thorough cleaning and better dredging effect. Moreover, when the conveying pipe 2 rotates, the spiral part 7 can be used to drive the worm wheel 82 to drive the first horizontal shaft 81 and the first gear 83 to rotate. At this time, through the second gear 85, the third gear 87 and the traveling wheels 88 can be driven to rotate synchronously, and the rotation directions of the upper and lower sets of traveling wheels 88 are opposite, which is convenient for the stable movement and operation of the device in the sewer pipe and is convenient for completing the efficient dredging of the sewer pipe.
