[0028] Please refer to Figure 1 , a pipeline cleaning device for water conservancy projects, including a water tank 1. Four corners at the rear of the water tank 1 are fixedly connected with driving wheels 3. One side of the upper end of the water tank 1 is fixedly connected with a liquid inlet mechanism 4;

[0029] The driving wheels 3 enable the device to move forward stably along the pipe wall. The liquid inlet mechanism 4 balances the air pressure inside and outside the water tank 1 through the conduction of air, so that the water in the water tank 1 can be stably input and output.

[0030] In the prior art, the driving wheel 3 includes a telescopic rod. A spring is arranged inside the telescopic rod. The spring is fixedly connected with a stabilizing rod. The outer end of the stabilizing rod is fixedly connected with a motor. The motor is rotationally connected with the wheel through a rotating shaft. During the implementation process, when the motor is started, the wheel starts to move forward along the pipe wall.

[0031] The front end of the water tank 1 is fixedly connected with a protection device 5. Four corners at the front of the protection device 5 are also fixedly connected with driving wheels 3. The inner bottom wall of the protection device 5 is fixedly connected with a driving device 10 and a water pumping device 2;

[0032] The protection device 5 blocks sediment and garbage from entering the inside of the device during the operation of the device. The driving device 10 can provide the power of rotational flushing for the cleaning device 7 and the scraping device 9. The water pumping device 2 pumps the water in the water tank 1 and conveys the water to the water diversion mechanism 6.

[0033] The center of the front end of the protection device 5 is fixedly connected with a water diversion mechanism 6. The driving device 10 is rotationally connected with a cleaning device 7, two water spraying devices 8 and a scraping device 9. Among them, the scraping device 9 is on the front side of the cleaning device 7;

[0034] The scraping device 9 can scrape off the thicker sediment and dirt on the pipe wall and cut the mud with high water content. The cleaning device 7 can wash the thinner sediment on the pipe wall to further clean the pipe wall. The water diversion mechanism 6 introduces the water pumped by the water pumping device 2 into the water spraying device 8. The water spraying device 8 sprays high-pressure water onto the pipe wall to soften the soil on the pipe wall and wash away part of the sediment.

When the water pressure in the water pipe is unstable, the water in the water tank 1 can ensure that the water pump 21 stably pumps water. When the water supply in the water pipe is cut off, the water in the water tank 1 can continue to maintain the operation of the device for a period of time.

[0038] Furthermore, to achieve the function of the inlet pipe 41 of the inlet liquid mechanism 4 to balance the pressure, refer to Figure 2 , the inlet liquid mechanism 4 includes an inlet pipe 41 fixed to the placement groove, and a sealing plug 42 is stuffed inside the inlet pipe 41, and a handle is fixedly connected to the upper end of the sealing plug 42;

[0041] During the implementation process, the motor is turned on, the driving motor 101 drives the rotating shaft 102 to rotate, and further drives the cleaning device 7 and the scraping device 9 to rotate.

[0042] Specifically, to achieve the function of the water diversion mechanism 6 to provide rotational power, refer to Figure 5, the water intake mechanism 6 includes a first water intake pipe 61 and a first annular housing 62.

[0043] First, the first water intake pipe 61 guides the water at the output end of the water pump 21 into the inner cavity of the first annular housing 62. Then the water automatically flows into the second annular housing 63, and then the second water intake pipe 64 conducts the water into the water spraying device 8. Since the second annular housing 63 can rotate with the rotating shaft 102, the second water intake pipe 64 and the second annular housing 63 can conduct the water flow during the process of following the rotating shaft 102.

A sponge brush 74 is fixedly connected to the outer surface of the support handle 73;

[0045] First, before the device enters the pipeline, the first telescopic rods 71 can be manually compressed to make the size of the cleaning device 7 adapt to the pipe wall. During the cleaning process, the sponge brush 74 is driven by the rotating shaft 102 to rotate to achieve the cleaning effect. The sponge brush 74 on the support handle 73 can be connected to the support handle 73 through structures such as snap fasteners commonly used in the prior art during implementation, which is convenient for later operation of the snap fasteners to replace the sponge brush 74.

[0047] The above-mentioned connecting water pipe 82 can connect a number of high-pressure water gun heads 81 on the same side together, and then the high-pressure water can be sprayed out through a number of high-pressure water gun heads 81 simultaneously through the second water intake pipe 64;

[0048] During the implementation process, the water diversion pipeline two 64 introduces water into the connecting water pipe 82. After the water enters the connecting water pipe 82, it is ejected through the high-pressure water gun head 81 to wash the pipe wall.

[0049] Specifically, to achieve the purpose of scraping the sediment in the pipeline by the scraping device 9, refer to Figure 4 , the scraping device 9 includes four second telescopic rods 91.
