These factors are not conducive to a quick and effective rescue
[0007] Moreover, the rescue methods disclosed in the prior art all require rescuers to be close to the trapped people to rescue them.
Because the current technology generally takes a long time to respond and rescue, the trapped people may have suffered suspension trauma and lost consciousness and mobility due to long-term suspension, which may easily lead to casualties and must be approached by rescuers.
[0008] In actual rescue, it is often precisely because of factors such as high altitude, high tower height, strong wind, and ice-covered lines that operators fall from heights; this will cause two problems: First, rescuers need to carry a large number of heavy rescue vehicles. It takes a lot of manpower and time for the equipment to climb up the iron tower and walk on the power line, and the rescuers will also be in danger because of these factors; second, the rescuers cannot reach the trapped people to start rescue

Embodiment 1
[0043] In one or more embodiments, a rescue system for an accidental fall from a height of a power transmission line is disclosed, referring to figure 1 ,include:
[0044] The unmanned aerial vehicle is used to carry one end of the insulating rope to ascend to the position of the power transmission line where the trapped person is, and hang the insulating rope on the power transmission line;
[0045] Insulated ropes are used to connect with live power transmission lines during rescue; at the same time, they provide high-altitude fixed points for descenders;
[0046] The descending device is used to slowly descend the trapped persons; one end of the descending device is connected with an insulating rope, which serves as a high-altitude fixed point of the descending device.
[0047] Specifically, in order to prevent the impact of the discharge of the transmission line on the UAV, the distance between the UAV and the transmission line should be kept at least 1 meter.

Embodiment 2
[0060] In one or more implementations, a rescue method for a power line falling from a height under live conditions is disclosed, refer to figure 2 , including the following procedures:
[0061] Step 1: Rescuers choose an insulated rope with sufficient length, connect the UAV and descender to the insulated rope, tie a knot at a suitable position, connect the lock and counterweight, and turn on the power of the UAV;
[0062] Step 2: Rescuers control the drone to rise above the trapped people, use the drone to hang the insulating rope on the transmission line near the trapped person, and make the part of the insulating rope with the lock close to the trapped person when descending , to make it easy to get. After the trapped people get the rope, the drone releases the insulating rope, and then monitors the scene aside;
[0063] Step 3: The trapped person buckles the lock into the knot of the descending device, and the connection between the rope and the wire is completed at thi...

Abstract
The invention discloses a rescue system and method for a high-altitude falling accident of a power transmission line under an electrified condition. The rescue system for the high-altitude falling accident of the power transmission line under the electrified condition comprises an unmanned plane, an insulating rope and a descent control device. The unmanned plane is used for carrying one end of the insulating rope to rise to the position of the power transmission line where a trapped person is located, and hanging the insulating rope to the power transmission line; the insulating rope is used for being connected with an electrified power transmission line during rescue; meanwhile, a high-altitude fixing point is provided for a descent control device; the descent control device is used for enabling the trapped person to descend slowly; one end of the descent control device is connected with the insulating rope and serves as the high-altitude fixing point of the descent control device. The rescue system and method for the high-altitude falling accident of the power transmission line under the electrified condition have the beneficial effects that a rescue device and method are simple and easy to implement, and a rescue can be completed without professional rescue training; mutual rescue is organized through an operation group, response speed is high, and the rescue can be rapidly completed before the trapped person suffers from a suspension wound.
Description
technical field [0001] The invention relates to the technical field of high-altitude emergency rescue, in particular to a rescue system and method for an accidental fall from a high place of a power transmission line under electrified conditions. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Live work on transmission lines is an important technical measure to ensure the safe and economical operation of the power grid, an indispensable technical means to improve the reliability of power supply and equipment integrity, and a major technical achievement in power production. Improving the reliability of power supply has become an important task at present, which requires us to vigorously carry out the maintenance and repair of live work to improve the reliability of power supply and the quality of power supplied to users. [0004] In recent...
