Self-locking hook of unmanned aerial vehicle rescue equipment for power transmission line

Abstract

The invention relates to a self-locking hook of unmanned aerial vehicle rescue equipment for a power transmission line, the self-locking hook comprises a base, a first hook and a second hook, the top end of the base is provided with a slot, a hanging hole is formed among the first hook, the second hook and the base, the base is movably connected with a limiting assembly, and a reset spring is arranged between the limiting assembly and the base; the self-locking hook has the advantages that the self-locking hook is hung on a power transmission line through the hanging hole formed among the first hook, the second hook and the base, the first hook cannot rotate due to the limitation of the limiting assembly on the first hook, and the second hook cannot rotate upwards due to the limitation of the guide arc section and can only rotate towards the slotting direction; the hung self-locking hook has a self-locking function, secondary damage caused by falling of the hook in the operation process can be effectively prevented, meanwhile, the whole self-locking structure does not adopt an electronic mode, operation is convenient and easy, meanwhile, electromagnetic interference factors are avoided, the failure rate is reduced, and operation safety is improved.

Problems solved by technology

[0002] With the development of my country's electric power industry, the iron towers of high-voltage transmission lines have been built higher and higher, and bigger and bigger, so it has brought great risks to electric power technicians during maintenance. Once the safety equipment appears during climbing operations Faults or other emergencies (such as sudden physical discomfort, weather changes), falling from a high place, being suspended in the air by a seat belt for a long time will cause suspension trauma (seat belt suspension syndrome) and gradually lose consciousness, plus There is no self-rescue ability due to factors such as fear, impact and injury, and the rescue time is very urgent. If the fall occurs in the "three-span" section or the large-span section such as mountains, canyons, and rivers, the rescue will be more difficult. Most of the transmission lines are located in the wild and remote. Rescue methods such as conventional high-altitude tools, high-altitude rescue vehicles, and helicopters are often limited by factors such as terrain, micro-meteorology, wire elasticity, and road traffic.
