Description

Adjustable cable marking device Technical field

The utility model relates to the technical field of cable channel safety facilities, and more particularly, to an adjustable cable marking device.

Background technique

The cable sign pile is also called: power cable sign pile, sign pile, natural gas sign pile passage vertical sign pile. Commonly used in the direction signs and warning signs of electric power, communication, gas, water, railway geographic pipeline routes. It is used to indicate the pipeline route on both sides of downtown, scenic area, green belt, bushes and top pipe.

At present, cable marker piles are generally installed on cable channels in fields, farmlands, green belts, etc. outside the sidewalks, highways and other channels. The road surface along the cable line is generally straight lines every 20 meters and the cable branches, turns, Install a cable marker pile at joints, entering buildings, etc. to warn people.

However, most of the cable marker piles used traditionally are made of concrete, which makes it heavy. When users need to carry it, it is very inconvenient, and the structure of traditional cable marker piles is simple and functional. Single, and it is very difficult to insert the cable marker pile into the ground.

In addition, the existing cable sign piles are used as signs and warning signs for cables buried in the ground. They are exposed for many years and are easily affected by external factors. Due to the current requirements of the safety ring standard of the power grid: the length of the power cable marking pile is fixed, the length is only 400mm, and the height of the exposed ground is only 150mm. If the location of the cable marking pile is installed in a green belt or industrial area, the cable marking pile is covered with soil, weeds, and foreign objects. It is difficult for the staff to find the specific location of the cable marking pile and the cable. As a result, the original cable marking piles are in the same shape, thus losing their due role and burying a lot of hidden safety hazards. If the operation management of the cables is not properly implemented by the operating personnel, it will directly lead to the damage of the underground cables in some infrastructure sites. The number of incidents has increased significantly. In recent years, there have been more than 20 incidents of construction digging and accidental damage to power in the area of a power supply bureau, causing direct and indirect economic losses of over 20 million yuan. Whether the cable marking pile can play its due role as a label warning for a long time is related to the safe and reliable operation of the power grid.
