Description

Technical Field

[0001] The utility model relates to the technical field of bare wire insulation spraying devices, specifically a bare wire insulation spraying device based on a drone. Background Technique

[0002] A bare wire insulation spraying device is a device specifically used for insulating the bare wires on power transmission lines. In the power industry, bare wires refer to wires without an insulating layer. Such wires are common in overhead transmission lines because they usually use air as a natural insulator. However, in order to improve safety, prevent short circuits and electric shock accidents, it is sometimes necessary to insulate the bare wires.

[0003] Existing bare wire insulation spraying devices are not convenient for local spraying on live 10kV bare wires where trees grow under and near 10kV distribution computer overhead lines. It is easy to cause faults such as short circuit tripping when the conductive trees that have been rained on are next to the wires, and it reduces the safety of construction workers. It cannot operate in complex terrains, etc., reducing practicality. Therefore, a bare wire insulation spraying device based on a drone needs to be proposed. Content of the Utility Model

Below the adjustable nozzle, a nozzle shutdown and flow control unit is fixedly connected. Below the nozzle shutdown and flow control unit, a detachable electric spray pot is movably connected.

[0006] Preferably, the number of the takeoff and landing fans is four, and the takeoff and landing fans are symmetrically arranged with the vertical center line of the drone platform as the axis of symmetry.
