[0025] Reference Figure 2 , 3, Hollow structure and center axis diameter size matching the inner surface of the sliding sleeve 2 is connected to the outer surface of the center axis 1 and is arranged on both sides of the center axis 1 respectively, four connecting forks are welded on each sliding sleeve 2, the connecting fork is fork U-shaped, with two prongs; On each prong, two opposite through holes are arranged respectively, such as the connecting fork marked as 3, its structure and function represent all connecting forks, other connecting forks have similar functions to connecting fork 3, which will not be repeated here; The connecting rod 4 of the rod-shaped steel structure is also provided with a through hole, which corresponds to the through hole on the prong of the fork-shaped component. When connecting, the connecting rod 4 is inserted into the middle of the prong, the through holes on the prong and the through holes on the connecting rod 4 are completely aligned, and then the pin shaft 5 is used to pass through the through holes of the prong and the connecting rod 4 in turn, realizing the connection of the two. After the pin shaft 5 is inserted, the fork-shaped component and the connecting rod 4 form a rotatable angular relationship, and the rotation angle can be adjusted according to actual needs; The other end of each connecting rod 4 connected with the sliding sleeve 2 is connected with the side beam 6 in the same pin shaft connection mode, the two side beams 6 are square steel pipes parallel to the center axis 1 and arranged on both sides of the center axis 1, the length is approximately equal to the length of the center axis 1, the side beam 6 is connected with the connecting seat of 8 wheels in the direction of the pipeline wall through welding, which has two symmetrical ears, the ears are provided with through holes for connection, the middle part is used for cooperation with the wheels, and the side of the side beam 6 has a flat welding surface. When welding, uniform welding is performed along the fitting part of the connecting seat and the side beam 6, a firm weld is formed, the connecting seat and the side beam 6 are connected stably, the middle part of the two ears of the connecting seat is provided with 6 walking wheels 7 and 2 driving wheels 8, the hub of the walking wheel 7 and the driving wheel 8 is provided with a mounting hole corresponding to the through hole of the ear of the connecting seat, the axle of the walking wheel 7 and the driving wheel 8 is inserted through the through hole of the ear of the connecting seat and the mounting hole of the hub, and nuts, washers and other accessories are installed at both ends of the axle to fasten the wheels to rotate around the axle, realizing the connection of the connecting seat and the wheels.

[0026] The two driving wheels 8 are oppositely arranged at the end of each side beam 6 on the same side, and the driving wheels 8 are connected to the motor 10 through the belt 9. The motor is a pneumatic motor, which is fixed on the motor base by screws, and the motor base is fixed on the side beam 6 by screws. The pneumatic motor is connected to the air compressor through the air pipe. After the air compressor is started, the pneumatic motor works to drive the driving wheel 8 to rotate through the belt 9 and drive the walking wheel 7 to realize the walking in the pipeline of the device.

[0027] On the outer surface of the central shaft 1 on the side close to both ends of the central shaft 1 and also the side of the sliding sleeve 2, two adjusting nuts 1101 are installed, on the other side of the sliding sleeve 2 away from the adjusting nuts 1101, two nuts 1102 are installed, the outer surface of the central shaft 1 is provided with threads matched with the adjusting nuts 1101 and the nuts 1102, a spring 12 is arranged between the sliding sleeve 2 and the nuts 1102, one end of the spring 12 is in contact with the sliding sleeve 2, and the other end is in contact with the nuts 1102; when the device is running in the pipeline, it encounters uneven places such as concave-convex sections or welds on the inner wall of the pipeline, the spring 12 plays a role of buffering and self-adaptive adjustment. The specific performance is as follows: when encountering convex parts, the spring 12 is compressed to absorb impact energy and reduce the direct impact on the walking wheel 7; when encountering concave parts, the spring 12 is stretched to push the sliding sleeve 2, ensuring that the walking wheel 7 is always in contact with the inner wall of the pipeline, realizing smooth and continuous walking.

[0028] This structure can make the device adapt to the complex conditions of the inner wall of different pipelines, significantly enhance the reliability and stability of the operation in the pipeline. Compared with the prior art, the present application reduces the need for frequent adjustment and maintenance, reduces the use cost and operation difficulty. Moreover, the precise control of the position of the sliding sleeve 2 by the adjusting nuts 1101 can adapt to pipelines of various diameters, greatly improving the versatility and practicality of the device. When the diameter of the pipeline is large, rotate the adjusting nuts 1101 away from the sliding sleeve 2, the sliding sleeve 2 moves towards the adjusting nuts 1101, the acute angle between the central shaft 1 and the connecting rod 4 increases, the straight-line distance between the side beam 6 and the central shaft 1 increases, the side beam 6 drives the walking wheel 7 and the driving wheel 8 to adhere to the inner wall of the pipeline, completing the adaptation to the change of the diameter of the pipeline. Conversely, when the diameter of the pipeline is small, the corresponding adjustment can be realized by performing the opposite operation.

[0029] Reference Figure 4At the other end away from the driving wheel 8, the central shaft 1 is connected with one end of the rotator 13, the other end of the rotator 13 is installed on the output shaft of the speed reducer 14, the other output shaft of the speed reducer 14 is installed with the nozzle assembly, the nozzle assembly includes the high-pressure gun rod 18 and the nozzle 19 connected with the high-pressure gun rod 18 and internally passing, the high-pressure gun rod 18 and the nozzle 19 have three groups, are arranged in a circle vertically, the rod end of each group of high-pressure gun rod 18 is connected with a nozzle 19 through screw thread, the angle interval of each group of high-pressure gun rod 18 and nozzle 19 is 120°, the arrangement can make the cleaning surface wider, and the cleaning effect is optimal. The speed reducer 14 is a worm gear reducer, the input shaft of the speed reducer 14 is connected with the output shaft of the driving motor 15, and the output shaft is directly connected with the worm 16 in the speed reducer 14. The driving motor 15 is a pneumatic motor, which is fixedly connected below the speed reducer through screw connection. The pneumatic motor is connected with the air compressor through an air pipe. After the air compressor is started, the driving motor 15 is started, and the output rotary power directly drives the high-speed rotation of the worm 16. The worm 16 is meshed with the worm gear 17, and the rotation of the worm 16 drives the worm gear 17 to complete the rotary motion at right angles and rotates at a lower speed and a larger torque, thereby completing the conversion of speed reduction and torque increase. The rotation of the worm gear 17 drives the output shaft of the speed reducer 14 connected therewith to rotate.

[0030] The speed reducer 14 is internally designed with a hollow shaft and two output ends, and the output end of the speed reducer 14 is threadedly connected with the rotator 13. The rotator 13 is internally provided with a pair of closely matched inner and outer bearings. The inner bearing is tightly sleeved on the extended part of the hollow output shaft of the speed reducer 14 and synchronously rotates with the output shaft of the speed reducer 14. The outer bearing is arranged in a specially designed fixing sleeve, and the fixing sleeve is stably connected with the central shaft 1 through screw and pipe. In this way, when the speed reducer 14 operates, the central shaft 1 remains non-rotating, thereby ensuring the stable flow of water.

[0031] The end of the speed reducer 14 away from the central shaft 1 is directly threadedly connected with the high-pressure gun rod 18 through the hollow output shaft of the speed reducer 14. High-pressure water can enter the high-pressure gun rod 18 and the nozzle 19 from the water pump through the water inlet pipe, the central shaft 1, the rotator 13, and the speed reducer 14 after being pressurized. After the driving motor 15 is started, the inner worm 16 rotates, the worm 16 is meshed with the worm gear 17, and the hollow output shaft of the speed reducer 14 is driven to rotate through speed reduction and torque increase. The rotator 13 connected with the hollow output shaft rotates around the stationary outer bearing under the driving of the inner bearing. Since the hollow output shaft is directly connected with the high-pressure gun rod 18, the high-pressure gun rod 18 also rotates synchronously.

[0032] Working principle:

[0033] The pipeline high-pressure flushing device is transported to the cleaning site in a split form. After arrival, the actual pipeline diameter and specific conditions are considered for assembly. First, the hollow steel pipe structure center shaft 1 is placed in position, and one end of the water inlet pipe is connected to the center shaft 1 through a pipe fitting, and the other end is connected to the water pump. Then, the two hollow sleeves 2 are respectively sleeved on the outer surfaces of the center shaft 1 on both sides, connected through the connecting fork on the sleeve 2 and the connecting rod 4 and the side beam 6, fixed by the pin shaft 5, and the structure is stable. The wheel connecting seat is installed on the side beam 6, and the corresponding number of walking wheels 7 and drive wheels 8 are installed according to the requirements. At the same time, according to the diameter of the pipeline, the position of the sleeve 2 is adjusted by rotating the adjusting nut 1101 on the center shaft 1, so that the side beam 6 drives the walking wheel 7 to fit the inner wall of the pipeline, and the preliminary assembly is completed.

[0034] After assembly is completed, the working state is started. The air compressor is started to supply air to the air motor. By setting a high-precision flow control valve on the air pipe, the air flow into the air motor is accurately controlled, and the rotating speed of the drive wheel 8 is accurately adjusted, so that the walking speed and rotating speed of the device are accurately controlled. When the drive wheel 8 rotates and drives the walking wheel 7 to travel in the pipeline, the spring 12 between the sleeve 2 and the nut 1102 plays a buffering and self-adaptive adjusting function to ensure smooth operation.

[0035] At the same time, the driving motor 15 rotates to drive the worm 16 in the speed reducer 14 to rotate, and the worm 16 is meshed with the worm wheel 17 to realize speed reduction and torque increase, thereby driving the rotator 13 and the high-pressure gun rod 18 to rotate synchronously. The water flow pressurized by the water pump is sprayed from the high-speed rotating high-pressure gun rod 18 and the nozzle 19 through the water inlet pipe, the center shaft 1, the rotator 13, and the hollow shaft channel of the speed reducer 14, and the three groups of nozzles 19 distributed at 120° on the circumference can efficiently clean the inner wall of the pipeline in all directions without dead angle, thereby completing the pipeline cleaning work.

[0036] It should be noted that the above is the working process of the entire device, and the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.

[0037] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
