Composite color steel tile for wall

The invention belongs to the technical field of color steel tiles, in particular to a composite color steel tile for a wall. The composite color steel tile includes a floating platform, a fixed wall, a door hole, a color steel tile sliding wall, a door-shaped frame, sliding rails, a connecting rod, a sliding groove, a water wheel, a gear, a rack, a rotating shaft and a rotating pin; the fixed wall is arranged on the floating platform, and the door hole is formed in one side of the fixed wall; a rotating shaft is rotatably connected to the position, between the fixed wall and the edge of the floating platform, on the floating platform; the door-shaped frame is arranged at the position, between the rotating shaft and the fixed wall, on the floating frame; the sliding rails are slidably connected to the upper end and the lower end of the door-shaped frame, the sliding rail located under the door-shaped frame is fixedly connected to the floating platform, and the sliding rail located above the door-shaped frame is fixedly connected with the fixed wall; the rack is fixedly connected to the side, away from the fixed wall, of the door-shaped frame; and sea water pushes the water wheel to rotate to drive the color steel tile sliding wall to be attached to the door hole through the drive of the rotating shaft, the gear, the rack, the door-shaped frame and the connecting rod, and finally, the color steel tile sliding wall completely closes the door hole to prevent waves from entering a room and damaging experimental instruments.
