[0043] In an optional embodiment, the adjusting assembly 24 comprises a spring 241, a cylindrical block 242, a second threaded rod 243 and a bearing 244, the spring 241, the cylindrical block 242 and the second threaded rod 243 are all arranged inside the cylindrical groove 4, the cylindrical block 242 is located between the spring 241 and the second threaded rod 243, the two ends of the spring 241 are fixedly connected with the circular column 1 and the cylindrical block 242 respectively, the bearing 244 is installed on the side of the cylindrical block 242 away from the spring 241, and the second threaded rod 243 is inserted into the inside of the bearing 244, the second threaded rod 243 is rotationally connected with the bearing 244 and the cylindrical block 242, and the cylindrical block 242 is slidingly connected inside the circular column 1.

[0046] In the embodiment, when the pipeline wall of the pressure pipeline needs to be cleaned, the rotating disc 232 is matched with the corresponding type according to the size of the pipeline wall, so that the cleaning brush 231 is attached to the pipeline wall of the pressure pipeline. When the rotating disc 232 is replaced, the knob disc 2310 is rotated, the rotation of the knob disc 2310 drives the first threaded rod 238 to rotate, after the first threaded rod 238 is rotated out of the first threaded hole 237, the hexagonal insert block 236 can be slid out of the hexagonal groove 235, so that the rotating disc 232 can be replaced. The replaced rotating disc 232 is sleeved on the surface of the hexagonal insert block 236. The first threaded rod 238 is rotated to be screwed into the first threaded hole 237, so that the hexagonal insert block 236 is attached to the inside of the hexagonal groove 235, the replacement of the rotating disc 232 is realized. The second threaded rod 243 is rotated, the second threaded rod 243 is rotated in the second threaded hole 247, so that the connecting column 3 slides in the circular column 1. The movement of the connecting column 3 drives the first bolt 216 to slide in the arc-shaped groove 215, so that the support rod 214 rotates around the second bolt 217. Since the inside of each U-shaped plate 211 is provided with two parallel support rods 214, the support rod 214 adjusts the distance between the U-shaped plate 211 and the circular column 1 during rotation. After the distance between the U-shaped plate 211 and the circular column 1 is adjusted appropriately, the device is placed in the pressure pipeline with the corresponding diameter. When the U-shaped plate 211 is subjected to a force, the U-shaped plate 211 moves towards the circular column 1. The U-shaped plate 211 drives the support rod 214 to rotate during movement. The support rod 214 rotates on the surface of the first bolt 216, so that the connecting column 3 slides in the circular column 1. The connecting column 3 can stretch the spring 241 during sliding. Under the action of the spring 241, the roller 213 has a corresponding force with the inner wall of the pressure pipeline. Under the action of the friction between the roller 213 and the pressure pipeline, the circular column 1 does not rotate in the pressure pipeline when the rotating disc 232 and the cleaning brush 231 rotate. By rotating the second threaded rod 243, the device can be applied to pressure pipelines with different diameters, and the force between the device and the pressure pipeline can be adjusted, so that the device does not rotate during cleaning of the pipeline wall of the pressure pipeline, the application range of the device is improved. When the pipeline wall of the pressure pipeline is cleaned, the power lines of the second motor 234 and the first motor 228 are connected with the storage battery 222. When the wheel disc 226 is placed in the pressure pipeline, the square slide plate 224 slides in the Z-shaped plate 221 under the action of the gravity of the second U-shaped clamp block 225, the wheel disc 226, the square slide plate 224 and the storage battery 222, until the wheel disc 226 contacts the pipeline wall of the pressure pipeline with a corresponding force. The controller is operated to start the first motor 228 and the second motor 234. The operation of the second motor 234 drives the rotating disc 232 to rotate,The rotation of the rotating disc 232 drives the rotating of the cleaning brush 231, the cleaning brush 231 rotates in the pipe wall of the pressure pipeline, the operation of the first motor 228 drives the rotating of the wheel disc 226 through the linkage shaft 227, the wheel disc 226 rotates in the pipe wall of the pressure pipeline, thereby pushing the device to move in the pressure pipeline, and the cleaning of the pipe wall of the pressure pipeline and the descaling process are realized by the continuous rotation of the cleaning brush 231, which is beneficial to the movement of the device in the pipe wall of the pressure pipeline, thereby realizing the effect of cleaning the pipe wall of the pressure pipeline in the rotating of the cleaning brush 231.

[0047] It should be noted that the cylindrical round block 242 slides in the circular column 1 to drive the limiting sliding block 246 to slide in the limiting sliding groove 245, the limiting sliding groove 245 and the limiting sliding block 246 are arranged to facilitate the sliding of the cylindrical round block 242 in the circular column 1, and to avoid damage to the spring 241 caused by the rotation of the cylindrical round block 242 in the circular column 1.

[0048] It should be noted that the connecting column 3 can drive the support rod 214 to rotate on the surface of the second bolt 217, and the U-shaped plate 211 can move towards or away from the circular column 1 under the action of the first bolt 216 and the arc-shaped groove 215, two support rods 214 are rotatably connected in the interior of each U-shaped plate 211, 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, the spring 241 can be compressed or stretched when the U-shaped plate 211 is subjected to an external force, so that the device has a corresponding force on the pressure pipeline, and under the action of the friction force between the roller 213 and the pressure pipeline, the circular column 1 does not rotate in the pressure pipeline when the rotating disc 232 and the cleaning brush 231 rotate, and the device can move in the pressure pipeline when the wheel disc 226 rotates.

[0049] It should be noted that under the gravity of the second U-shaped block 225, the wheel disc 226, the square slide plate 224 and the battery 222, the square slide plate 224 slides in the Z-shaped plate 221 until the wheel disc 226 contacts the pipe wall of the pressure pipeline with a corresponding force, and the device can move in the pressure pipeline when the wheel disc 226 rotates in the pipe wall of the pressure pipeline, if the wheel disc 226 rotates and the device does not move, a weight can be added to the placing plate 223 to increase the force between the wheel disc 226 and the pressure pipeline, thereby enabling the device to move.

[0050] It should be noted that the number of clamping assemblies 21 is three, and arranged in a circular array on the surface of the circular column 1, under the action of the connecting column 3, so that the distance between the circular column 1 and the three U-shaped plates 211 is always the same, and then the rotating disc 232 uniformly applies force to the inner wall of the pressure pipeline, ensuring the cleaning effect of the pipeline wall.

[0051] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features.
