[0002] As the global demand for water resources continues to increase, water conservancy projects occupy an important position in the infrastructure construction of various countries. As a key component of water conservancy projects, the operating efficiency and life of water conservancy pipelines directly affect the effective utilization of water resources and the overall benefits of the project. However, due to long-term exposure to the natural environment, the walls of water conservancy pipelines are susceptible to corrosion and rust, which not only reduces the water delivery capacity of the pipelines, but may also cause pipeline ruptures, water leakage and other problems, seriously affecting the safety and reliability of water conservancy projects.

[0003] Traditional pipe wall rust removal methods mainly include manual rust removal, chemical rust removal and mechanical rust removal, etc. These methods have their own advantages and disadvantages. Among them, manual rust removal: This method relies on workers to manually grind and rust the inner wall of the pipe, which is inefficient and labor-intensive, and it is difficult to meet the needs of large-scale water conservancy projects. Mechanical rust removal uses mechanical equipment for rust removal. Although it is more efficient, it is difficult to enter some narrow or complex pipes due to the large size of the equipment, and its scope of application is limited. Therefore, a water conservancy pipeline wall rust removal device is needed to solve the above problems. Summary of the invention

The auxiliary wheel is docked with the end of the auxiliary plate to make the auxiliary wheel cooperate with the universal wheel to improve the stability of the equipment when it moves or rotates on the inner wall of the pipeline.

[0010] Preferably, an adjusting component is provided on the side of the left triangular plate, and the adjusting component includes an axis plate fixed on the outer side of the left triangular plate, a movable plate is inserted into the interior of the axis plate through a through groove, and the end of the movable plate is connected to a pressure plate, the pressure plate is in contact with the surface of the rubber tube, a locking bolt is inserted into the front side of the axis plate through a threaded hole, and the axial end of the locking bolt is in contact with the surface of the movable plate, and the movable plate can move in the axis plate to push the pressure plate during the movement, and the movement of the pressure plate can push the annular groove end of the rubber tube, which is convenient for offsetting the outlet of the rubber tube, and then the sandblasting direction of the rubber tube can be adjusted.

[0011] Preferably, the inner wall of the pressure plate is designed to be V-shaped, and the inner wall of the pressure plate is provided with teeth grooves. The surface of the rubber tube is provided with an annular groove that matches the pressure plate. The V-shaped design on the inner side of the pressure plate can ensure that various types of rubber tubes can be pushed with an angle offset.

[0012] Preferably, an annular groove is opened on the inner wall of the limiting ring plate, and a plurality of balls are embedded and arranged in the annular groove. The bottom end of the ball contacts the inner wall of the annular groove of the ring plate, and the balls rotate by friction between the ring plate and the limiting ring plate, thereby ensuring the smoothness of rotation between the ring plate and the limiting ring plate.

The rotation of the gear ring can control the synchronous rotation of the straight steel cylinder and the frame, and then the adjusted rubber cylinder is controlled to rotate, so that the abrasive particles sprayed by the rubber cylinder can impact and remove rust on the inner wall of the pipe during rotation.

[0014] The present invention has at least the following beneficial effects: 1. By setting up a sandblasting tube, movable components and spray head accessories, the rust removal operation on the inner wall of the pipeline can be realized. Compared with the traditional structure, the device connects the end of the sandblasting tube with the hexagonal cylinder shaft, and the piston rod end of the first cylinder is extended and retracted to push the universal wheel to contact the inner wall of the pipeline. The auxiliary plate is connected to the outside of the piston rod end of the first cylinder, and the auxiliary plate surface is provided with an auxiliary wheel. The auxiliary wheel and the universal wheel can cooperate to adapt to the inner wall of pipelines with different inner diameters, and play a better auxiliary support operation to ensure the stability of the frame suspended in the pipeline. The staff holds the sandblasting tube in the pipeline and pushes it. The abrasive sprayed from the sandblasting tube can be sprayed from the rubber tube to remove the rust on the inner wall of the pipeline. The sandblasting tube can be bent freely, and the overall volume of the movable component is small, so it can be adapted to polish some narrow or complex pipelines and improve the polishing effect.

[0015] 2. By setting the adjustment component, the direction of the rubber tube sandblasting nozzle can be preparatory adjusted. The device sets the rubber tube at the end of the straight steel tube. The rubber tube and the end of the straight steel tube can move freely. By pushing the movable plate, the movable plate can push the pressure plate to push the rubber tube. The rubber tube can be tilted on the surface of the straight steel tube, which is convenient for tilting the rubber tube, thereby changing the spraying angle, and the inner tube can be directly sprayed and rust-removed on one side.

[0016] 3. By setting up a driving component, the surrounding sandblasting and rust removal operation of the inner wall of the pipeline can be realized. The device is connected to the right side of the right triangular plate through a flange connection plate. The shaft end of the driving motor rotates to control the rotation of the gear. The gear can control the rotation of the gear ring, so that the gear ring drives the sleeve ring plate to rotate on the surface of the limit ring plate. The rotation of the gear ring can drive the right triangular plate auxiliary support to rotate. At the same time, the sleeve ring plate can drive the straight steel cylinder to rotate synchronously, and then control the abrasive sprayed from the rubber cylinder to perform surrounding rust removal on the inner wall of the pipeline, further improving the rust removal effect of the rust on the inner wall of the pipeline.

[0017] 4. By setting the sandblasting tube and the hexagonal barrel shaft, the hexagonal barrel shaft and the sandblasting tube can be separated independently. In daily use, the sandblasting tube and the hexagonal barrel shaft are connected by bolts to complete the rust removal operation of the pipeline. The detachable design between the sandblasting tube and the hexagonal barrel shaft can also be convenient for the staff to place them in daily life. After the sandblasting tube is separated from the hexagonal barrel shaft, the sandblasting equipment and the sandblasting tube can be used independently, so that the sandblasting tube can perform hand-held blasting and rust removal operations on the outside of the pipeline, further improving the rust removal effect.

[0018] 5. By setting up a winding rack, the sandblasting tube can be wound and placed on the outside of the winding rack for daily placement. The sandblasting tube can be automatically stored after the sandblasting operation is completed, reducing the trouble of manual operation and making full use of the space outside the sandblasting machine to ensure that the sandblasting tube can be stored neatly and orderly when not in use.

[0030] An annular groove is formed on the inner wall of the limiting ring plate 42 , and a plurality of balls 43 are embedded and arranged in the annular groove. The bottom ends of the balls 43 are in contact with the inner wall of the annular groove of the sleeve ring plate 44 .

[0031] A driving motor 51 is installed at the top of the hexagonal cylindrical shaft 41, and a gear 52 is connected to the shaft end of the driving motor 51.

The protective cover plate 55 consists of a baffle end and a ring plate end.

[0032] The surface of the hexagonal cylinder shaft 41 is designed with a hexagonal structure as a whole. The ring plate 44 and the limit ring plate 42 are designed to be rotated. When the gear ring 53 rotates, the gear ring 53 can control the ring plate 44 to rotate on the surface of the limit ring plate 42, which is convenient for controlling the overall rotation of the movable component 3 to ensure that the abrasive particles sprayed by the rubber cylinder 46 can remove rust from the inner wall of the pipeline.

The damage cannot be discovered in time, thereby ensuring the convenience of daily maintenance of the straight steel cylinder 45.

[0033] The universal wheel 33 can be pushed by the piston rod end of the first cylinder 32, so that the universal wheel 33 can be against the inner wall of the pipeline to adapt to different pipeline states. At the same time, the universal wheel 33 can rotate freely, which is convenient for the frame 31 to move in the pipeline. The cylinder seat end of the first cylinder 32 can move freely on the inner wall of the left triangular plate 313, so that the first cylinder 32 can be adjusted to a suitable position, which is beneficial to the rotation state of the frame 31.

After the movable plate 392 is moved and adjusted, the locking bolt 394 moves in the threaded hole of the shaft plate 391 and then contacts the surface of the movable plate 392, thereby locking and fixing the movable plate 392.

[0034] The V-shaped design on the inner side of the pressure plate 393 can ensure that various types of rubber tubes 46 can be pushed with an angle offset. The tooth groove on the inner wall of the pressure plate 393 cooperates with the ring groove on the surface of the rubber tube 46 to adjust the deflection of the rubber tube 46 to ensure the stability of the adjustment of the rubber tube 46. When the ring plate 44 rotates on the surface of the limiting ring plate 42, the friction ball 43 between the ring plate 44 and the limiting ring plate 42 rotates to ensure the smoothness of the rotation between the ring plate 44 and the limiting ring plate 42.

[0035] Working principle: According to the attached Figure 1 With attached Figure 4 As shown, during use, the sandblasting tube 2 can be butted against the right side of the hexagonal cylindrical shaft 41 by bolts. Figure 6 As shown, the first cylinder 32 is started, and the piston rod end of the first cylinder 32 is extended and retracted to push the universal wheel 33 to move, so that the universal wheel 33 and the auxiliary wheel 38 are in contact with the inner wall of the pipe. At this time, in order to facilitate the rotation of the right triangular plate 311, the second cylinder 35 is used to assist the first cylinder 32; Secondly, after placing the equipment inside the pipeline, the sandblasting equipment 1 can be started. The abrasive particles of the sandblasting equipment 1 are ejected through the sandblasting tube 2 and enter the inside of the hexagonal cylinder shaft 41. The abrasive particles pass through the straight steel cylinder 45 and are ejected from the rubber cylinder 46, so as to facilitate the impact and rust removal operation on the inner wall of the pipeline. At this time, the sandblasting tube 2 can be slowly pushed by the hand. Figure 4 As shown, the driving motor 51 is started, and the shaft end of the driving motor 51 can control the driving motor 51 to rotate, and the driving motor 51 can drive the gear ring 53 to rotate, so that the gear ring 53 drives the flange plate 54 to control the frame 31 to rotate, and the frame 31 can drive the universal wheel 33 and the auxiliary wheel 38 to rotate in the pipeline. At this time, the gear ring 53 rotates and can synchronously drive the collar plate 44 to drive the surface of the limit ring plate 42 to rotate, and then control the rotation of the ball 43. The rotation of the collar plate 44 can also drive the straight steel cylinder 45 to rotate on the surface of the inner liner 47, and the straight steel cylinder 45 can drive the rubber cylinder 46 to rotate, and then the inner wall of the pipeline is derusted. Finally, before sandblasting, Figure 7As shown, the movable plate 392 can be pushed, and the movable plate 392 pushes the pressure plate 393. The pressure plate 393 can apply force to the groove on the surface of the rubber tube 46 during movement, thereby making the rubber tube 46 tilt and bend at the end of the straight steel tube 45. When the frosted particles are sprayed out from the rubber tube 46, the rust removal operation on the inner wall of the pipeline is facilitated.
