An overhead cable police aircraft and its installation method

Abstract

The present invention provides an aerial cable police aircraft and its installation method. Its body consists of two hemispheres to form a hollow sphere structure, and the front and rear sides of the sphere are provided with connecting mechanisms for assembling the two hemispheres into a sphere. The connection mechanism includes a hinge on one side of the sphere and a locking structure on the other side of the sphere; one of the hemispheres is fixed with a hanging piece, and the hanging piece includes a first hook connected to the overhead cable. A hook part and a second hook part used to connect the sling during installation; the other said hemisphere is provided with a through hole for the sling to pass through during installation; the hinge is an automatic reset hinge. By adopting the present invention, the two hemispheres can be safely, conveniently and quickly assembled on the overhead cable. During the process, there is no need to hang the middle part of the cable through equipment such as pulleys, helicopters, elevators, etc., and workers can operate on the ground, reducing large-scale The installation difficulty and potential safety hazards of the sphere on the overhead line reduce the labor intensity of the workers and improve the working efficiency.

Description

technical field [0001] The invention relates to the field of transmission line identification, in particular to identification products used in power overhead lines to warn aviation aircraft and ships traveling in rivers and seas. Background technique [0002] The height of the tower of the high-voltage transmission and distribution line has reached 110 meters. With the development of my country's economy and the opening of low-altitude flight, the number of various types of aircraft is increasing, and the frequency of use is increasing. It is used in agriculture, sightseeing, photography and many other aspects. Flight activity is also becoming more active. Low-altitude flight brings convenience to our life, but it also brings some serious safety problems. For example, some cables cross the river, cross the sea and the air, if there is no proper sign to remind the pilot of the aircraft and the pilot of the ship, the power line The location and altitude will seriously affect ...

AI Technical Summary

Problems solved by technology

However, the existing police aircraft generally use pre-twisted wire clamps to fix and install it on the lightning protection cable. During installation, it needs to be suspended in the middle of the cable through equipment such as pulleys, helicopters, and elevators. It belongs to high-altitude operations, and the construction is extremely difficult. inconvenient, dangerous

In addition, the installation quality will be different due to the different technical proficiency and responsibility of the construction personnel, and the fixed point of the pre-twisted wire clip is exposed outside the police aircraft, which is easily affected by the environmental climate and birds staying on the pre-twisted wire. Corrosion, loosening of pre-twisted wires, etc.

Especially in the environment of strong wind and snow, the spherical surface is hit by strong wind and loaded by snow, which will increase the load of overhead cables, leaving a safety hazard for the safe production and operation of transmission lines in the future
