By combining a vertical plate, rotating gears, sliding rods, a box, and a spraying mechanism, it solves the problem of existing spraying devices being inefficient in spraying steel structures. However, this device still has the following drawbacks: low spraying stability during use; the spray pattern cannot automatically adapt to the steel structure components being processed; it is not convenient for large-area spraying of the steel structure surface; spraying is limited to the four corners; and it cannot target gaps in the steel structure.

[0006] In this solution, a servo motor rotates a screw, driving the main moving seat to move within the guide groove. As the main moving seat moves up and down, it sprays the steel structure surface through a split-flow fan-shaped nozzle. Meanwhile, a synchronous electric telescopic rod is used to extend and retract, adjusting the hinge angle of the connecting plate and the spraying distance and range of the split-flow fan-shaped nozzle to adapt to different sizes of steel structure widths.

[0014] In this design, the screw rotates, driving the drive gear to rotate, which in turn drives the driven gear plate to rotate, causing the clamping seat to rotate. This, combined with the up-and-down moving split fan-shaped spray nozzle, allows for all-around spraying.
[0015] Compared with the prior art, the beneficial effects of this utility model are: 1) The servo motor rotates the screw, driving the main moving seat to move in the guide groove. At this time, the main moving seat moves up and down, and the feed pump pumps the internal rust inhibitor into the three-way pipe and sprays it out through the split fan-shaped nozzle. The split fan-shaped nozzle sprays the steel structure surface. At this time, the hinge angle of the connecting plate is adjusted by the synchronous electric telescopic rod to adjust the spray distance and spray range of the split fan-shaped nozzle to adapt to the width of steel structures of different sizes, and effectively spray the corners of the steel structure. 2) The screw rotates, driving the drive gear to rotate, which in turn drives the driven gear plate to rotate, causing the clamping seat to rotate. This, combined with the up-and-down moving split fan-shaped spray nozzle, allows for all-around spraying. Attached Figure Description
