[0027] Example 1

[0028] Reference Figure 1 , 2 and 4, which is the first embodiment of the utility model, provides a metal pipeline anti-corrosion and rust removal device, including a telescopic rust removal mechanism 100 and a dust removal mechanism 200;

[0029] The telescopic rust removal mechanism 100 includes a wire brush 101, an electric telescopic rod 102, a transmission roller 103 and a motor 104. The wire brush 101 is fixed on the electric telescopic rod 102, and the electric telescopic rod 102 is fixed on the front side of the transmission roller 103. The transmission roller 103 is provided with two groups, and the two groups of transmission rollers 103 are respectively arranged on both sides of the metal pipe to be rusted, and the transmission roller 103 is connected to the motor 104.

[0030] The dust removal mechanism 200 includes a sealed connection cover 201, a dust collection cover 202, a dust collection pipe 203, a dust collection fan 204, and a dust collection box 206. The dust collection cover 202 is fixed to the rear side of the wire brush 101, the sealed connection cover 201 is arranged on the rear side of the dust collection cover 202, the sealed connection cover 201 is slidably connected to the electric telescopic rod 102, and the winding roller 205 is arranged on the sealed connection cover 201; the dust collection pipe 203 is wound on the winding roller 205, and the two ends of the dust collection pipe 203 are respectively The sealing connection cover 201 is respectively connected with the dust collection hood 202 and the dust collection fan 204, and the dust collection fan 204 is connected with the dust collection box 206; the sealing connection cover 201 is provided with a sealing ring 2011 adapted to the pipe to be derusted, and the sealing ring 2011 is nested in the front end of the dust collection pipe 203; the rear side of the sealing connection cover 201 is also arranged with a limit baffle 2012 used in conjunction with the sealing connection cover 201, and the limit baffle 2012 is fixed on the ground to limit the backward movement distance of the sealing connection cover 201.

[0031] In this embodiment, when in use, the pipe to be derusted is placed on the transmission roller 103, and then the motor 104 is started to drive the two sets of transmission rollers 103 to rotate, and the transmission rollers 103 drive the pipes connected thereto to rotate continuously.

[0032] At the same time, the electric telescopic rod 102 is started, and the wire brush 101 is pushed gradually into the pipe by the electric telescopic rod 102. The brush wires on the surface contact the inner wall, thereby achieving a rust removal effect during the rotation of the pipe.

[0033] When the electric telescopic rod 102 pushes the wire brush 101 to move, the wire brush 101 drives the dust cover 202 to be inserted into the pipe synchronously, and the dust suction fan 204 is started, so that the dust suction fan 204 sucks the rust debris generated in the process of pipe rust removal into the dust collecting box 206 through the dust suction pipe 203.

[0034] In this process, when the sealing connection cover 201 is tightly attached to the end of the pipeline, the sealing ring 2011 covers the outside of the pipeline, forming a semi-sealed structure for the pipeline to prevent rust from escaping.

[0035] Example 2

[0036] Reference Figures 1 to 5 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that: the dust removal mechanism 200 also includes a winding roller 205, a winding gear 207 and a telescopic rack group 208 used in conjunction with each other, as well as a duct bracket 209, a ball screw 210, and a motor 211, and the end of the winding roller 205 is connected to a winding shaft 2051, and the winding shaft 2051 is rotatably mounted on the winding bracket 2052, and the winding bracket 2052 is fixed on the sealing connection cover 201; the winding shaft 2051 is connected to the end of the winding roller 205, and the winding shaft 2051 is rotatably mounted on the winding bracket 2052, and the winding bracket 2052 is fixed on the sealing connection cover 201; the winding shaft 2051 is connected to the end of the winding roller 205, and the winding shaft 2051 is connected to the end of the winding roller 205, and the winding shaft 2051 is connected to the sealing connection cover 201; ... One end of 051 passes through the winding bracket 2052 and is fixedly connected to the winding gear 207. The top of the winding gear 207 is meshed and transmission-connected with the telescopic rack group 208. The telescopic rack group 208 is arranged at the bottom of the electric telescopic rod 102. A duct bracket 209 is also arranged on the front side of the winding roller 205. A pipe threading slot is provided on the duct bracket 209 for the dust collection pipe 203 to pass through. A ball screw 210 is connected to the bottom of the duct bracket 209, and the end of the ball screw 210 is connected to the motor 211.

[0037] The remaining structures are the same as those of Example 1.

[0038] In this embodiment: when the sealing connection cover 201 is in close contact with the end of the pipe and the position remains unchanged, the electric telescopic rod 102 continues to push the wire brush 101 and the dust cover 202 to move, and the telescopic rack set 208 meshes with the winding gear 207, driving the winding shaft 2051 to rotate in the positive direction, and the winding shaft 2051 gradually lengthens the dust collection pipe 203 to facilitate the use with the moving dust cover 202. At the same time, the motor 211 is started, so that the motor 211 drives the ball screw 210 to rotate, and drives the dust collection pipe 203 to move back and forth horizontally along the direction of the ball screw 210 through the pipe bracket 2052, so that the dust collection pipe 203 outputs evenly.

[0039] After the dust removal is completed, the motor 211 is stopped, the electric telescopic rod 102 is retracted, and then the sealing connection cover 201, the wire brush 101 and the dust cover 202 are retracted together. When the sealing connection cover 201 moves to the limit baffle 2012, the movement is blocked and the position remains unchanged. The electric telescopic rod 102 continues to be retracted. At this time, the telescopic rack group 208 is engaged with the winding gear 207, driving the winding shaft 2051 to rotate in the opposite direction.

[0040] The dust collection pipe 203 is rolled up with the winding shaft 2051 to prevent entanglement and knotting. At the same time, the motor 211 is started through the cooperation of the synchronous wheel 211 and the synchronous belt 212, so that the motor 211 controls the duct bracket 2052 again to drive the dust collection pipe 203 to move reciprocatingly horizontally along the direction of the ball screw 210, so that the dust collection pipe 203 is evenly rolled up.

[0041] It is worth noting that the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
