The limit sliders 246 are slidably connected to the circular column 1 through the limit slots 245.

When the cleaning brush 231 is in contact with the cleaning surface 236 of the cleaning brush 231, the cleaning brush 231 is in contact with the cleaning surface 236 of the cleaning brush 231. When the cleaning brush 231 is in contact with the cleaning surface 236 of the cleaning brush 231, the cleaning brush 231 is in contact with the cleaning surface 236 of the cleaning brush 231. When the cleaning brush 231 is in contact with the cleaning brush 231, the cleaning brush 231 is in contact with the cleaning surface 236 of the cleaning brush 231. The second threaded hole 247 rotates inside, so that the connecting column 3 slides inside the circular column 1. The movement of the connecting column 3 causes the first latch 216 to slide inside the arc-shaped groove 215, so that the support rod 214 rotates with the second latch 217 as the axis. Since two parallel support rods 214 are provided inside each U-shaped plate 211, the support rod 214 adjusts the distance between the U-shaped plate 211 and the circular column 1 during the rotation. After the distance between the U-shaped plate 211 and the circular column 1 is adjusted appropriately, when the device is placed inside a pressure pipe of corresponding diameter, a force is applied to the U-shaped plate 211, which can move the U-shaped plate 211 toward the direction of the circular column 1. The U-shaped plate 211 drives the support rod 214 to rotate during the movement. The support rod 214 rotates on the surface of the first latch 216, so that the connecting column 3 slides inside the circular column 1. The connecting column 3 slides During the cleaning process, the spring 241 can be stretched, and under the action of the spring 241, the roller 213 can have a corresponding force on the inner wall of the pressure pipe. Under the action of the friction between the roller 213 and the pressure pipe, the circular column 1 does not rotate inside the pressure pipe when the rotating disk 232 and the cleaning brush 231 rotate. By rotating the second threaded rod 243, the device can be adapted to pressure pipes of different diameters and the force between the device and the pressure pipe can be adjusted, thereby avoiding the problem of the device rotating during the cleaning process of the pipe wall of the pressure pipe, improving the scope of application of the device. When cleaning the pipe wall of the pressure pipe, the power lines of the second motor 234 and the first motor 228 are connected to the battery 222. When the wheel disc 226 is placed inside the pressure pipe, under the action of the gravity of the second U-shaped block 225, the wheel disc 226, the square slide 224 and the battery 222, the roller 213 and the cleaning brush 231 rotate. The square slide plate 224 slides inside the Z-shaped plate 221 until the wheel disc 226 contacts the pipe wall of the pressure pipe and has a corresponding force. The operation controller starts the first motor 228 and the second motor 234. The operation of the second motor 234 drives the rotating disk 232 to rotate. The rotation of the rotating disk 232 drives the cleaning brush 231 to rotate. The cleaning brush 231 rotates in contact with the pipe wall of the pressure pipe inside the pressure pipe. The operation of the first motor 228 drives the wheel disc 226 to rotate through the linkage shaft 227. The wheel disc 226 and the pressure pipe rotate in contact, thereby pushing the device to move inside the pressure pipe. As the cleaning brush 231 continues to rotate, the pipe wall cleaning and descaling process of the pressure pipe is realized, which is conducive to moving the device inside the pipe wall of the pressure pipe, thereby achieving the effect of cleaning the pipe wall of the pressure pipe when the cleaning brush 231 rotates.

It should be noted that the sliding of the cylindrical block 242 inside the circular column 1 drives the limiting slider 246 to slide inside the limiting groove 245. The setting of the limiting groove 245 and the limiting slider 246 facilitates the sliding of the cylindrical block 242 inside the circular column 1, thereby preventing the cylindrical block 242 from rotating inside the circular column 1 and causing damage to the spring 241.

It should be noted that: when the connecting column 3 moves, the support rod 214 can be driven to rotate on the surface of the second pin 217, and under the action of the first pin 216 and the arc-shaped groove 215, the U-shaped plate 211 can be moved toward or away from the circular column 1. The interior of each U-shaped plate 211 is rotatably connected to two support rods 214, and the two support rods 214 are parallel to each other, so that the U-shaped plate 211 is always parallel to the circular column 1. When a force is applied to the U-shaped plate 211, the spring 241 can be compressed or stretched, so that the device can have a corresponding force on the pressure pipe. Under the action of the friction between the roller 213 and the pressure pipe, the circular column 1 does not rotate inside the pressure pipe when the rotating disk 232 and the cleaning brush 231 rotate, and when the wheel 226 rotates, the device can be pushed to move inside the pressure pipe.

It should be noted that: under the action of gravity of the second U-shaped block 225, the wheel 226, the square skateboard 224 and the battery 222, the square skateboard 224 slides inside the Z-shaped plate 221 until the wheel 226 contacts the pipe wall of the pressure pipe and has a corresponding force. When the wheel 226 rotates on the pressure pipe wall, the device can move inside the pressure pipe. If the device does not move when the wheel 226 rotates, the load can be added to the placement plate 223 to increase the force between the wheel 226 and the pressure pipe, so that the device can move.

It should be noted that there are three clamping assemblies 21, which are arranged in a ring array on the surface of the circular column 1. Under the action of the connecting column 3, the distance between the circular column 1 and the three U-shaped plates 211 is always the same, so that the force exerted by the rotating disk 232 on the inner wall of the pressure pipe remains uniform, ensuring the effect of cleaning the pipe wall.

Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
