Description

Technical Field

[0001] This utility model relates to the field of drone spraying device technology, specifically to a combined multi-rotor drone that can be used for anti-rust spraying of power transmission and distribution towers. Background Technology

[0002] Transmission towers are the support points for overhead lines. A single-circuit transmission tower has one circuit installed on it, while a double-circuit transmission tower has two circuits installed on it. A single circuit means that one load has one power supply circuit, while a double circuit means that one load has two power supply circuits.

[0003] Currently, rust removal using rust-treated solutions can also be used to remove rust from transmission towers. Although using rust-treated solutions can save the rust removal step and transform the original rust layer into a dense chelated film that adheres to the substrate surface, giving the substrate a better anti-corrosion effect, the spraying process mostly involves workers climbing to a designated height to spray the rust-preventive spray on a designated location, which is quite dangerous for the workers. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the aforementioned shortcomings of existing technologies, this utility model provides a combined multi-rotor drone that can be used for rust prevention spraying on power transmission and distribution towers.

The output end of the servo motor 34 is fixedly connected to a buckle plate 36 through a connecting ring 35. The top end of the buckle plate 36 is fixed inside the gun body 31 through a pin. The top ends of the buckle plate 36 and the paint can 4 are both fixed with hinge seats 391. A drive rod 39 is sleeved between the two sets of hinge seats 391.

[0030] The front end of the drone device 1 is equipped with a supplementary light 11, and one end of the power compartment 32 is electrically connected to the servo motor 34 via a switch 33. Through the combination structure of the drone device 1 and the paint can 4, the user can remotely control the drone device 1 to perform paint protection and rust prevention operations at a designated location.
