Safety warning device for power transmission line

Abstract

The invention discloses a safety warning device for a power transmission line. The safety warning device comprises a left moving plate, a right fixing plate is arranged at one side of the left movingplate, the left moving plate and the right fixing plate are both of U-shaped structures, and openings of the two plates are oppositely arranged. The left moving plate and the right fixing plate are fixedly connected through connecting shafts which are symmetrically arranged front and back, the left ends of the connecting shafts are inserted into the left moving plate and are in threaded connectionwith an inner cavity of the left moving plate, and the right ends of the connecting shafts are inserted into the right fixing plate and rotationally connected with a motor arranged on the right sideface of the right fixing plate through a transmission mechanism. The inner side of the opening end of the left moving plate is fixedly connected with a supporting plate, a hydraulic oil tank and a hydraulic pump are arranged on the upper surface of the supporting plate, and hydraulic lifting columns are arranged on the upper surface of the left moving plate and the upper surface of the right fixing plate. According to the safety warning device, the length and the height of a warning frame can be adjusted according to different sites, so that the warning board can be adjusted to the position where pedestrians can pay attention, and meanwhile the dismounting and carrying are convenient.

Description

technical field [0001] The invention relates to the technical field of warning devices, in particular to a power transmission line safety warning device. Background technique [0002] Electricity is an indispensable energy in our life, work and study. Without electricity, our society may be paralyzed. Therefore, when there is a sudden power outage in a certain area, the power company will assign a rescue engineering team to the fastest speed. To complete the power rescue and timely supply power to the people. [0003] When carrying out emergency repair and erection of power transmission lines, it is generally more dangerous. Construction workers need to wear insulation equipment to carry out construction. During construction, warning signs need to be placed outside to remind the public. Because the warning signs have been exposed for a long time. It will be corroded, which is not convenient for long-term use. Therefore, it is necessary to place the warning signs in the warn...

Problems solved by technology

[0003] It is generally more dangerous when carrying out emergency repair and erection of transmission lines. Construction personnel need to wear insulation equipment to carry out construction. During construction, warning signs need to be placed outside to remind the masses, because the warning signs have been exposed for a long time It will be corroded and not easy to use for a long time. Therefore, it is necessary to place the warning sign in the warning frame to improve the service life. However, the length and height of the existing warning frame are fixed, and it is not easy to place in some narrow places. , so it is not easy to transport, and difficult to disassemble
