Description

Technical Field

[0001] This utility model relates to the field of bridge and structural engineering technology, specifically to a drone-based prefabricated coating repair device for bridge maintenance. Background Technology

[0002] Bridge maintenance involves regular inspections and repairs to ensure that bridges remain in good working order. Bridge coating is a key process in bridge corrosion protection. It primarily involves spraying anti-corrosion paint onto the outer surface of the bridge, forming a protective coating that isolates the bridge from direct contact with moisture, oxygen, and corrosive media (such as chloride salts). This reduces corrosion on the bridge's outer surface and significantly extends the structure's service life.

[0003] As bridges age, the coating on their outer surface gradually peels off due to weathering and rain erosion. Therefore, relevant personnel need to regularly use equipment to repair the bridge coating.

[0004] However, the lack of an adjustment mechanism in the existing technology makes it inconvenient to adjust the direction and angle of spraying, and also makes it inconvenient to spray and repair different parts of the bridge, resulting in low repair efficiency. In order to solve the shortcomings of the lack of an adjustment mechanism in the existing technology, this application sets up components such as a reversing shell and a positioning shell, thereby achieving the effect of adjusting the spraying direction and angle by setting up components such as a reversing shell and a positioning shell, thereby improving repair efficiency. Therefore, a new solution is needed to solve this problem. Utility Model Content

The output end of the second motor, the second worm 9 and the second worm gear 8, drive the sleeve 10 and nozzle 11 to rotate up and down. The first worm gear 6 and the second worm gear 8 can limit the rotation amplitude of the nozzle 11, thereby preventing the nozzle 11 from contacting and colliding with the propellers and other components of the UAV carrier 1.

[0020] Two positioning grooves 12 are formed on the outer surface of the sleeve 10. Each positioning groove 12 is connected to the inside of the sleeve 10.

[0026] The positioning tube 24 can clamp and limit the hose 25, and the second worm gear 8 can drive the camera 23 to rotate with the spray nozzle 11 through the U-shaped clamp 22, so that the camera 23 can easily observe the position of the spray repair.

[0027] The implementation principle is as follows: The UAV carrier 1 is started and hovered at a predetermined position. The pump is started, and the pump delivers the paint from the storage tank 21 to the spray nozzle 11 through the hose 25 and flange 19 and sprays it out. The first motor is started, and the output end of the first motor drives the first worm 7 to rotate. The first worm 7 drives the first worm wheel 6 to rotate.
