Description

Technical Field

[0001] The invention relates to the technical field of unmanned aerial vehicles, and in particular to a cabin paint spraying system based on an unmanned aerial vehicle. Background Art

[0002] Drones, as unmanned aircraft, achieve unmanned flight through radio remote control or autonomous control. Among them, tethered drones use their unique tethered cables to connect to ground power sources as a power source, abandoning the limitations of traditional lithium batteries and thus having the ability to hover in the air for a long time.

[0003] Existing tethered drones are usually used in high-risk areas due to their ability to hover in the air for a long time. When dealing with the complex structures and varying heights of ships, traditional manual spraying faces significant safety risks when operating at high altitudes and in narrow spaces. Drone spraying operations can efficiently cover large areas, which not only improves work efficiency, but also significantly enhances the safety of operations, effectively ensuring the safety of ships during maintenance.

[0004] When the existing tethered UAV is in use, in order to further improve the efficiency of the spraying operation, the spraying equipment on the UAV is connected to the material storage box on the ground through a spiral centrifugal pump and a material guide hose according to the electrical connection between the tethering cable and the ground power supply box. However, since the end of the material guide hose is fixedly connected to the spiral centrifugal pump, when the UAV needs to be raised or lowered according to demand during the spraying operation, the material guide hose will accumulate on the ground, which will not only cause the material guide hose to be tangled, making it difficult to store the material guide hose, but will also cause passers-by to trip. In order to be able to evenly reel or release the material guide hose, a UAV cabin spray material system is now provided, which can eliminate the disadvantages of the existing device.
