[0026] It includes a pipeline 1, a guide block 2 is placed inside the pipeline 1, an inner frame 3 is fixedly installed at the top of the guide block 2, a connecting rope 4, the connecting rope 4 is wound around the top of the inner frame 3, one end of the connecting rope 4 is wound around an outer frame 5, a circle of equally spaced nozzles 6 are arranged on the outer surfaces of the inner frame 3 and the outer frame 5, a circle of equally spaced electric push rods 7 are arranged on the outer surface of the guide block 2, a pulley 8 is fixedly installed on the telescopic rod of the electric push rod 7, and the pulley 8 is lapped on the inner wall of the pipeline 1;

[0027] When spraying a vertical power pipeline, place the outer frame 5 on the outer surface of the bottom end of the pipeline 1, place the guiding block 2 inside the top end of the pipeline 1, then turn on the electric push rod 7. After that, the telescopic rod of the electric push rod 7 pushes the pulley 8 to move outward and contact the inner wall of the pipeline 1. Then, lower the guiding block 2, and under the action of gravity, the guiding block 2 drives the inner frame 3 to move downward. The inner frame 3 sprays materials on the inner wall of the power pipeline. After that, the inner frame 3 drives the connecting rope 4 to move downward, and then the connecting rope 4 drives the outer frame 5 to move upward along the outer surfaces of the guiding wheel 10 and the moving wheel 12. The outer frame 5 sprays materials on the outer wall of the power pipeline.

[0028] Further, a placement frame 16 is fixedly installed at the top of the inner frame 3. A liquid extraction pump 17 is arranged on the inner wall of the placement frame 16. The water outlet of the liquid extraction pump 17 is threadedly connected to one side of the inner frame 3. The water inlet of the liquid extraction pump 17 is connected to a hose 18. The top end of the hose 18 is connected to a storage tank 19. A connecting pipe 20 is arranged on the outer surface of the hose 18, and the bottom end of the connecting pipe 20 is threadedly connected to one side of the outer frame 5.

[0029] During the coating process, place the storage tank 19 on the bracket. By turning on the liquid extraction pump 17, the liquid extraction pump 17 pumps the materials from the inside of the storage tank 19 into the inner frame 3 and the outer frame 5 respectively through the hose 18 and the connecting pipe 20, and then sprays them through the nozzle 6 for feeding. The placement frame 16 protects the liquid extraction pump 17, so that the liquid extraction pump 17 moves with the inner frame 3 through the placement frame 16.

[0035] Working principle: When spraying the power pipeline, by turning on the guide block 2, the inner frame 3 is driven to slide along the inner wall of the power pipeline to complete the feeding of the inner wall of the power pipeline. Then, the connecting rope 4 is driven to move leftward, and then the outer frame 5 is driven to move rightward to complete the feeding of the outer wall of the power pipeline, improving the practicability of the device and the feeding efficiency. In addition, by clamping the pipeline 1 with the limiting frame 15, the support frame 9 is stabilized, and further the guide wheel 10 is stabilized. The guide wheel 10 and the driving wheel 12 guide the connecting rope 4, making the operation of the device more stable.
