Rescue system and method for transmission line fall accident

Abstract

The invention discloses a rescue system and method for a power transmission line falling from a height, comprising: an unmanned aerial vehicle, which is used to carry a hook connected with a descending device, ascend to the position of the power transmission line where the trapped person is, and place the hook Hanging on the power transmission line; the hook is used to connect with the power transmission line during rescue; at the same time, it provides a high-altitude fixed point for the descending device; the descending device is used to make the trapped person slowly descend; one end of the descending device is connected to The hook is connected as the high-altitude fixed point of the descender. The rescue device and method of the present invention are simple and easy to implement, and can be completed without professional rescue training; mutual rescue is organized through the operation team, and the response speed is fast, and the rescue can be completed quickly before the trapped person suffers from suspension trauma.

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 a power transmission line falling from a height. 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] UHV and EHV transmission lines have the characteristics of wide regional span, high distance to the ground, complex path environment, "three spans" (crossing high-speed railways, expressways and important transmission channels), high risk, and changeable meteorological disasters. [0004] During a large number of high-altitude operations such as tower climbing, wiring, accessory installation, tightening and unwinding, and acceptance of transmission lines, operators may fall from heights due to emergencies such as physical conditions, working environment, and wire torsion. [0005] After the acci...

AI Technical Summary

Problems solved by technology

However, this method requires professional rescuers to go up to the rescue, and the requirements for rescuers are relatively high. They must go through years of training and practice to be competent. Moreover, many key details such as the breaking strength of the rope equipment and the strength of the rescue system should also be paid attention to during rescue. Problems, not conducive to quick and effective rescue

[0008] Moreover, the rescue methods disclosed in the prior art all require rescuers to be close to the trapped people to rescue them.

Because high-altitude rescue of transmission lines is different from ordinary high-rise building (structure) rescue, rescuers often need to have special skills such as tower climbing, live work, wire shifting, etc. Social rescue forces (armed police, fire brigade, civil rescue teams, etc.) Often have insufficient mastery of the special skills of high-altitude rescue on the line, and cannot effectively carry out rescue work

[0009] 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.

[0010] 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; the second is that the rescuers cannot reach the trapped people to start rescue
