[0002] In the field of water conservancy engineering, corrosion and rust will occur on the outer wall of water conservancy pipelines during operation. At present, the common methods for removing rust from the outer surface of water conservancy pipelines are sandblasting with a sandblasting machine or manual grinding with a wire brush installed on a pipeline cleaning tool.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a rust removal device for the outer surface of water conservancy engineering pipelines, which has the following beneficial effects:

[0016] (1) This utility model is provided with a movable plate, a lower mounting plate and an upper mounting plate. The movable plate is equipped with movable wheels at the four corners of its bottom surface. When in use, the movable plate can be moved to directly below the pipe to be treated. The top surface of the movable plate is symmetrically equipped with an electric push rod, and the output end of the electric push rod is connected to the lower mounting plate. The first guide slide rod fixedly installed on the movable plate is sleeved in the first guide slide sleeve fixedly installed on the lower mounting plate. Therefore, the working height of the lower mounting plate can be adjusted by the electric push rod. The top surface of the lower mounting plate is symmetrically welded with a lower bracket, and the upper mounting plate is fixedly welded with an upper bracket. The upper bracket and the lower bracket are symmetrically opened on opposite sides. The system features a sliding groove with a sliding block embedded within it. A semi-circular rotating plate is fixedly mounted on each sliding block. Connecting blocks are symmetrically fixed to the side walls of the upper and lower brackets, and fixing bolts can be screwed into these connecting blocks. This allows the upper and lower brackets to be connected and fixed. Depending on the installation height of the pipe to be derusted, the lower and upper mounting plates can be moved synchronously by an electric push rod. This aligns the central axis of the tangential surfaces of the two sets of semi-circular rotating plates with the central axis of the pipe's tangential surface, enabling subsequent pipe derusting. This system is suitable for derusting water conservancy pipelines at different installation heights, offering a wider range of applications and greater practicality.

[0017] (2) This utility model is provided with a fixed connecting plate, a semi-circular rotating plate, and an arc-shaped rust removal plate. The fixed connecting plate is fixedly welded between the inner walls of the semi-circular rotating plates on the same side, and a nut is installed in the center of the fixed connecting plate. An adjusting threaded rod shaft is screwed into the nut. A bearing seat is installed at the bottom end of the adjusting threaded rod shaft, and the bearing seat is fixedly installed on the arc-shaped rust removal plate. A second guide slide rod is symmetrically fixedly installed on the top surface of the arc-shaped rust removal plate. A second guide sleeve is symmetrically fixedly installed on the fixed connecting plate, and a second guide slide rod is sleeved inside the second guide sleeve. Therefore, when the worker rotates the adjusting threaded rod shaft, the arc-shaped rust removal plate can be moved along the second guide slide rod until the wire brush fixedly installed on the inner side of the arc-shaped rust removal plate abuts against the outer surface of the pipe. By adjusting the position of the arc-shaped rust removal plate, it can be applied to the rust removal of the outer surface of pipes with different diameters. On the other hand, a semi-gear ring is fixedly installed on the outer wall of the semi-circular rotating plate, so that the two semi-gear rings can be combined into one gear ring. At the same time, an installation cavity is opened in the lower bracket, and a servo motor is installed in the installation cavity. The output end of the servo motor is connected to a drive shaft, and a drive gear is fixedly installed on the drive shaft. The drive gear meshes with the semi-gear ring. So when the servo motor drives the drive shaft to rotate, it can drive the semi-circular rotating plate, together with the fixed connecting plate and the arc-shaped rust removal plate, to rotate. At this time, the rotating wire brush can be used to automatically clean the rust on the surface of the pipe. A rust collection box is placed on the lower mounting plate to collect the cleaned rust debris for subsequent processing. Thus, automatic rust removal driven by the servo motor is realized, saving manpower, improving rust removal efficiency, and making it more practical. Attached Figure Description

An electric push rod 2 is symmetrically mounted on the top surface of the movable plate 1, and its output end is connected to the lower mounting plate 4. A first guide slide rod 17 fixedly mounted on the movable plate 1 is sleeved within a first guide slide sleeve 7 fixedly mounted on the lower mounting plate 4. Therefore, the height of the lower mounting plate 4 can be adjusted using the electric push rod 2. A lower bracket 8 is symmetrically welded to the top surface of the lower mounting plate 4, and an upper bracket 10 is fixedly welded to the upper mounting plate 15.

This allows for derusting operations on water conservancy engineering pipes at different installation heights, with a wider range of applications and stronger practicality. In addition, this utility model is equipped with a fixed connecting plate 13. A semi-circular rotating plate 16 and an arc-shaped rust-removing plate 9 are connected by a fixed connecting plate 13 welded to the inner wall of the semi-circular rotating plate 16 on the same side.
