[0017] Please refer to Figures 1-3 , an embodiment provided by the present utility model:

[0018] A high-pressure rotary jet drill pipe cleaning mechanism includes a high-pressure rotary jet pipe 1. A push plate 2 is slidably connected inside the high-pressure rotary jet pipe 1. A protection shell 3 is fixedly connected to the bottom of the push plate 2. A motor 4 is fixedly connected inside the protection shell 3. The bottom of the output shaft of the motor 4 is fixedly connected to a liquid storage tank 5. A limit pipe 6 is fixedly connected to the outside of the liquid storage tank 5. A telescopic pipe 7 is slidably connected inside the limit pipe 6. One end of the telescopic pipe 7 away from the liquid storage tank 5 is fixedly connected to a brush plate 8. A flexible brush 801 is arranged on the brush plate 8, and the flexible brush 801 is in contact with the inner wall of the high-pressure rotary jet pipe 1.

[0019] Furthermore, the high-pressure rotary jetting pipe 1 serves to inject cement into the ground, and the propulsion mechanism 10 serves to drive the push plate 2 to move within the high-pressure rotary jetting pipe 1. The exterior of the push plate 2 can be slidably connected to the high-pressure rotary jetting pipe 1, serving to scrape off impurities on the inner wall of the high-pressure rotary jetting pipe 1.

[0020] Furthermore, the protective shell 3 is fixedly connected to the motor 4 to maintain the stability of the motor 4. The output shaft of the motor 4 is fixedly connected to the liquid storage tank 5, such that the motor 4 can drive the liquid storage tank 5 to rotate after starting. The liquid storage tank 5 serves to store water, and the liquid filling pipe 501 facilitates the user to add water into the liquid storage tank 5.

[0021] Furthermore, the liquid storage tank 5 is fixedly connected to the limiting pipe 6, such that when the liquid storage tank 5 rotates, it can drive the limiting pipe 6, the telescopic pipe 7, the brush plate 8, and the flexible brush 801 to rotate. The limiting pipe 6 is slidably connected to the telescopic pipe 7 to maintain the stability of the telescopic pipe 7. The telescopic pipe 7 is fixedly connected to the brush plate 8 to maintain the stability of the brush plate 8. The brush plate 8 is provided with a flexible brush 801, and the flexible brush 801 is in contact with the inner wall of the high-pressure rotary jetting pipe 1, such that when the flexible brush 801 rotates, it can clean the inner wall of the high-pressure rotary jetting pipe 1.

[0022] Furthermore, through holes 802 are formed inside the brush plate 8, such that the water in the liquid storage tank 5 can flow to the flexible brush 801 through the limiting pipe 6, the telescopic pipe 7, and the through holes 802, facilitating the flexible brush 801 to clean the inner wall of the high-pressure rotary jetting pipe 1.

[0023] Furthermore, the return spring 9 provides elastic force to push the flexible brush 801 on the brush plate 8 into contact with the inner wall of the high-pressure rotary jetting pipe 1.

[0024] Working principle: Pour water into the liquid storage tank 5 through the liquid filling pipe 501. Extend the push plate 2 into the high-pressure rotary jetting pipe 1 through the propulsion mechanism 10. The return spring 9 pushes the flexible brush 801 into contact with the inner wall of the high-pressure rotary jetting pipe 1. The water flows to the flexible brush 801 through the limiting pipe 6, the telescopic pipe 7, and the through holes 802. The motor 4 drives the liquid storage tank 5, the limiting pipe 6, the telescopic pipe 7, the brush plate 8, and the flexible brush 801 to rotate. The flexible brush 801 cleans the inner wall of the high-pressure rotary jetting pipe 1. The propulsion mechanism 10 pushes the push plate 2 and the flexible brush 801 to move within the high-pressure rotary jetting pipe 1, pushing out the impurities inside the high-pressure rotary jetting pipe 1, thus achieving the effect of cleaning the inside of the rotary pipe and solving the problems raised in the background art.
