Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a lifting mechanism for a cabin of an unmanned aerial vehicle and an unmanned inspection vehicle. Background Art

[0002] With the rapid development of electric power technology, people's demand for electricity is getting higher and higher. Therefore, the normal operation of substations is particularly important to people. However, due to the complex spatial installation of substation equipment, the current conventional inspection methods include manual and wheeled robot inspections. This inspection method often fails to inspect in place and has inspection blind spots. It cannot cover the external insulation, leads, wire clamps, connectors, meters, etc. of various equipment in the substation, making it difficult to ensure the quality, safety and efficiency of the inspection.

[0003] The existing substation inspection vehicle with automatic take-off and landing of drones, although it avoids the need for inspectors to get off the vehicle to take off and recover the drone, still requires personnel to drive the vehicle to the destination. In addition, the scissor-fork connecting rod mechanism used in the automatic take-off and landing mechanism is lightweight, but the lifting is not stable, which affects the take-off and landing of the drone. When driving on uneven roads, the overall mechanism will slow down, and long-term use will affect the service life of the drone nest. After each use, it is extremely inconvenient to refuel the vehicle and charge the nest. Utility Model Content
