Slope direct-buried cable protection device for mountainous area

Abstract

The invention relates to the field of power transmission line cables. Aiming at displacement damages caused by the rain washing to a pre-buried cable in a mountainous area in the prior art, the invention provides a slope direct-buried cable protection device for the mountainous area. The device is characterized in that a cable is provided with cable protection sleeves at set intervals; parts, located at two sides of the cable protection sleeve, of the cable are respectively provided with a pre-buried part buried in soil; elastic parts are respectively disposed between the pre-buried parts and the cable protection sleeves. The device is simple in structure. During the laying of a slope direct-buried cable, angle irons are respectively buried at two sides of the cable at intervals, and the cable is sleeved by a protection sleeve layer. The protection sleeves are connected with the angle irons through an adjustable elastic device. When the soil covering the surface of the cable is lost, the cable can be fixed through the angle irons, and the elastic device can counteract the impact on the cable from a part of external forces, thereby achieving the protection of the cable. The device can reduce the impact damages caused by the external force to the cable, protect the cable, and guarantee the power utilization reliability of a scenic region.

Description

technical field [0001] The invention relates to the field of power transmission line cables, in particular to a protective device for directly buried cables on slopes in mountainous areas. Background technique [0002] With the development of my country's economy, society and power grid construction, the load of electricity consumption continues to increase. In recent years, people's living standards have been continuously improved, spiritual life has been continuously enriched, and tourism has become a new fashion. In order to protect the original appearance of scenic spots, while providing clean and beautiful For the mountainous scenic area, the original transmission tower method has been gradually replaced by cables because it is not in harmony with the landscape. The geology of mountainous areas is generally dominated by rocks, the terrain is complex, and the cable laying method is relatively simple. Most of them are directly buried. However, the disadvantage of direct bu...

AI Technical Summary

Problems solved by technology

The geology of mountainous areas is generally dominated by rocks, the terrain is complex, and the cable laying method is relatively simple. Most of them are directly buried. However, the disadvantage of direct burying is that the surface of the cable will be displaced and damaged after being washed by the soil in the mountainous rainy season. In order to better protect the cable , To ensure the reliability of power supply in scenic spots, this protection device is specially invented
