The two springs 204 are fixedly connected to the inner wall of the movable column 2. When the two movable rods 201 move towards the outside of the movable column 2, the baffles 203 can squeeze the springs 204.

[0025] On one inner side of the movable column 2, a first electric push rod 206 is fixedly installed. The output end of the first electric push rod 206 is fixedly installed with a driving block 207, and the driving block 207 extends between the two movable wheels 205. Both sides of the driving block 207 are inclined, and the two movable wheels 205 are respectively in contact with the inclined sides of the two driving blocks 207. When the first electric push rod 206 pushes the driving block 207 to descend, the two movable rods 201 can be pushed to move outside the movable column 2. When the driving block 207 ascends, in cooperation with the spring 204, the two movable rods 201 can be made to approach each other, so as to adjust the position of the scraping plate 202, so that the scraping plate 202 can contact the inner wall of pipes of different sizes.

[0026] A toothed ring 210 is fixedly installed on the outer surface of the movable column 2. On one side of the outer surface of the rust removal column 1, a driving motor 208 is fixedly installed, and the output end of the driving motor 208 is fixedly installed with a first gear 209. The first gear 209 meshes with the toothed ring 210. When the driving motor 208 drives the first gear 209 to rotate, the gear can be driven to rotate, so as to drive the movable column 2 to rotate.

[0027] A plurality of sliding grooves 101 are formed on the outer surface of the rust removal column 1. Two movable rings 102 are movably connected inside the sliding grooves 101, and the movable rings 102 can move along the sliding grooves 101.

[0028] A plurality of guiding components are arranged on the opposite sides of the two movable rings 102. The guiding components include guiding wheels 104. On the opposite sides of the two movable rings 102, extension arms 103 are movably connected, and the two extension arms 103 are both movably connected with the guiding wheels 104. When the two movable rings 102 move in opposite directions, the two extension arms 103 can push the guiding wheels 104 to move, so that the guiding wheels 104 can contact the inner walls of pipes of different sizes.

[0029] Two second electric push rods 105 are fixedly installed on the outer surface of the rust removal column 1, and the output ends of the two second electric push rods 105 are respectively fixedly connected with the two movable rings 102.

[0030] Two rotating shafts 301 are movably installed inside the fixed head 3, and the sandblasting gun 302 is fixedly connected with the two rotating shafts 301. On one side of the outer surface of the fixed head 3, a second gear 303 is movably installed, and the second gear 303 is fixedly connected with one of the rotating shafts 301. When the second gear 303 rotates, the sandblasting gun 302 can be rotated, so as to adjust the angle of the sandblasting gun 302.

[0031] On one side of the outer surface of the fixed head 3, a third electric push rod 305 is fixedly installed, and a rack 304 is fixedly installed at the output end of the third electric push rod 305. The rack 304 meshes with the second gear 303. The third electric push rod 305 pushes the rack 304 to move, and the moving rack 304 can drive the second gear 303 to rotate.

[0032] Inside the rust removal column 1, there is a motor for driving the fixed head 3 to rotate. The motor inside the rust removal column 1 can drive the fixed head 3 to rotate.

[0033] The working principle of the present utility model is as follows: After the inside of the pipeline is cleaned, the first electric push rod 206 pushes the driving block 207 downward, so that the two movable rods 201 can move outward from the movable column 2 until the two scraping plates 202 are pushed into contact with the inner wall of the pipeline, and then the device can be withdrawn from the pipeline. During this process, the two scraping plates 202 will bring out the sand and rust that have fallen inside the pipeline, and the gear drives the toothed ring 210 to rotate, so as to adjust the positions of the two scraping plates 202, which is convenient for cleaning the rust and sand that have fallen inside the pipeline.
