When the brushing head 30 moves vertically upward following the connecting beam 10, one brushing roller 32 can brush the corrosion protection agent sprayed from the discharge port 311 to the steel On the wall 200; when the brush head 30 moves vertically downward following the connecting beam 10, another brush roller 32 can brush the corrosion protection agent sprayed from the discharge port 311 onto the steel wall 200. In other words, when the brush head 30 moves vertically up and down, the corrosion protection agent sprayed from the discharge port 311 can be applied to the steel wall 200.
[0069] Optionally, the base 31 includes a plate body 312 and a storage bin 313 fixed to the plate body 312; the brush roller 32 is rotatably arranged on the plate body 312; the discharge port 311 is strip-shaped, and the discharge port 311 is painted along The extending direction of the roller 32 is arranged in the storage bin 313, the discharge port 311 is communicated with the internal space of the storage bin 313, and the storage bin 313 is externally connected with a supply pipe 33.

At the same time, the two motors 211 work to make the connecting beam 10 move down at a uniform speed, and the brush head 30 moves down synchronously. The corrosion protection agent is extruded from the discharge port 311 by The application roller 32 of the application head 30 applies evenly. After the connecting beam 10 reaches the bottom end of the vertical guide rail 40, the two motors 211 reverse to make the connecting beam 10 return to the top end of the vertical guide rail 40.
[0090] (7) After the connecting beam 10 is returned to its position and above the water surface, the brush head 30 is translated for a certain length along the connecting beam 10 and locked, so that the new painting position overlaps the painted area. After completion, repeat step (6).
