Uncoiling method and system for guide rope of electric power of unmanned helicopter

Abstract

The invention discloses a static cable electric laying method and a system of an unmanned helicopter. A pay-off stand is carried by an unmanned helicopter, one end of the static cable is wound on the pay-off wheel of the pay-off stand, the other end thereof sequentially passes through the conduit tube and the rope blasting device of the pay-off stand, and the free end of the static cable is attached with weight; when the unmanned helicopter achieves the appointed drop point, the weight drops under the action of braking force; when the weight achieves the appointed position, a land station sends an instruction to the unmanned helicopter for asking the helicopter to continue the mission flight course, the unmanned helicopter flies to next line tower according to the flight course set in advance. The invention uses an aircraft the density of which is larger than the air density, therefore, the anti-wind capability is strong, and safe flying control requirements in complicated environmentcan be met. The unmanned helicopter can hover at a proper airspace according to the operation requirements, the camera carried on the unmanned helicopter can assist the land station to judge the distance to the personnel on the tower, thus ensuring the safe flying distance.

Description

technical field [0001] The invention relates to high-voltage overhead transmission line installation technology, in particular to a method and system for deploying high-voltage cable guide ropes by using an unmanned helicopter. Background technique [0002] In the field of high-voltage overhead transmission line installation, it is often difficult to deploy the guide rope after the online tower is erected. , these means increase the intangible cost for the line erection in a sense. At the same time, in the process of deploying the guide rope, we expect the guide rope to be deployed with tension, so as to avoid the accident caused by the sag problem of the guide rope. [0003] The prior art related to the patent of the present invention includes: [0004] 1) Patent Publication No. CN 1083979A discloses a method for setting off a remote control model helicopter. The realization method of this technology is to use the model remote control helicopter to carry the guide rope, ...

AI Technical Summary

Problems solved by technology

This technical method has the following advantages and disadvantages: this technology has the advantages of being easy to deploy and having low environmental requirements for deployment, but at the same time this technology also reflects its shortcomings from some angles, for example, it is difficult to achieve much lift for remote control model helicopters. Requirements for the release of wires between the towers. After the flight height of the model helicopter reaches a certain height, it is difficult for the operator to distinguish the attitude of the remote control model helicopter, and give normal control fingers to achieve stable flight with tension. At the same time, during the flight, The remote control model helicopter is difficult to fly according to the ideal flight route due to human visual deviation, and the guide rope is difficult to accurately fall on the crossarm of the line tower, and the subsequent deployment is difficult

Advantages and disadvantages of this technology: This technology has the advantages of fast speed and strong wind resistance, but the implementation of this technology has the following difficulties. The aircraft cannot hover, and it is difficult to cooperate with the staff above the wire tower during the laying-out operation. And the aircraft has strict requirements on the take-off and landing sites, so it is not suitable for field operations. Often because of the problem of the take-off and landing sites, the aircraft can only reach the setting-off operation area after flying several kilometers of routes.

Advantages and disadvantages of this technology: This technology requires very little ground conditions

However, there are the following problems: if a hydrogen airship is used, there is a danger of explosion, and it is inconvenient to fly near existing high-voltage cables; if a helium airship is used, there will be high cost of helium, difficulties in recycling, and difficulties in supplying helium in economically underdeveloped areas, etc. Problem; if a hot air balloon is used, the gas fuel carried by the aircraft is easy to leak, which may easily cause burning accidents during the flight

However, it is difficult to accurately calculate the path and landing point of the rocket carrying the guide rope, which may cause accidental injuries to the staff on the tower or the ground personnel.
