Abstract

The invention provides an underground cable protective device convenient for maintenance and belongs to the technical field of electric power facilities. The device comprises a cable, a protection mechanism used for protecting the cable and a support mechanism arranged below the protection mechanism. The protection mechanism comprises a plurality of protection tubes and a plurality of three-way connectors connected with the protection tubes. A plurality of flexible rubber strips are arranged on both sides of the inner part of each protection tube. First joints, perpendicular to the protection tubes, of the three-way connectors are provided with caps. The support mechanism comprises a base plate and side plates arranged on the two sides of the base plate. The lower portions of the side plates are provided with several rotating shafts. Several cover plates are arranged on the side plates. The lengths of the cover plates are equal to the lengths of the protection tubes. The both ends of the cover plates are semi-circular. The protection mechanism and the support mechanism are both of non-metallic materials. The device of the invention can protect underground cables, provides convenience for maintenance after faults occur to the underground cables, can effectively reduce the construction intensity of the underground cables and can raise the construction efficiency.

Description

technical field [0001] The invention relates to the technical field of electric power facilities, in particular to an underground cable protection device which is convenient for maintenance. Background technique [0002] In the modern society, due to the shortage of urban land, high traffic pressure, city appearance construction and other reasons, many cables have also gone underground from the original overhead. Compared with overhead lines, underground cables have the advantages of small footprint, reliable power transmission, and strong anti-interference ability. [0003] Underground cables are damaged by rats, ants, soil corrosion and other unsafe factors, which increase the possibility of cable leakage. In addition, due to the increased load, self-aging and some construction units' awareness of power facility protection during construction Thin, brutal construction leads to the constraints of factors such as frequent failure of cables and failure to supply power normal...
