Technical Field
The invention relates to the technical field of electric power facilities, in particular to an underground cable protection device convenient to maintain.
Background
After the modern society, due to the reasons of urban land shortage, high traffic pressure, city appearance construction and the like, a plurality of cables are also increasingly overhead to the underground. Compared with an overhead line, the underground cable has the advantages of small occupied area, reliable power transmission, strong anti-interference capability and the like.
The underground cable has unsafe factors such as rat damage, ant gnawing, soil corrosion and the like, the possibility of electric leakage of the cable is increased, in addition, the load is increased, the self aging is realized, the protection consciousness of partial construction units on electric power facilities is thinner in the construction process, the cable is often subjected to fault due to brutal construction, the power supply can not be normally carried out, and the like, and the potential hazard of external force damage threatens the safe operation of a cable line. Therefore, the life of residents and the production stoppage of factories are influenced, and especially, the loss caused by scientific research units such as industrial and mining hospitals cannot be estimated.
Once the underground cable is damaged, it is time consuming and labor intensive to repair the cable. Generally, it takes a long time to find a fault point, and after finding the fault point, the earth surface is excavated, the damaged part of the cable is cut off, and then an intact cable is reconnected by an insulation joint, and finally the cable is buried. Usually, a cable is damaged, the repair time is dozens of hours, and the repair cost is quite high. If the cable is laid, the protective tube is installed, and the maintenance is more troublesome. Some cables need to be pulled out completely, the cables need to be replaced again, or a damaged section of the cable needs to be replaced, and then the cable needs to be installed in the protective pipe again. Some excavate a section of earth's surface near the fault point, cut off protection tube and cable, after changing the new cable, connect the protection tube, bury the cable well. The maintenance is time-consuming, labor-consuming and very troublesome.
Therefore, a device for protecting underground cables is needed, which can play a certain role in fixing cables, protect electric wires and cables, prolong the service life of the electric wires and cables, facilitate the maintenance of the damaged cables, improve the construction efficiency, reduce the construction strength, ensure the smooth and safe operation of the underground cables, and ensure the normal operation of people's life and production.
The patent No. CN106253192A discloses a device of protection wire and cable, belong to electrical equipment technical field, comprising a bottom plate, be equipped with a plurality of fixed establishment on the bottom plate, fixed establishment includes the bottom plate by the bottom to last setting, middle fixed plate and an upper fixed plate, the bottom plate, the side of middle fixed plate and upper fixed plate is together fixed through a side fixed plate, be equipped with parallel arrangement's wire and cable protection pipe between bottom plate and the middle fixed plate, be equipped with parallel arrangement's wire and cable protection pipe between middle fixed plate and the upper fixed plate. The wire and cable fixing device is simple in structure, reasonable in design and convenient to install, can fix wires and cables to a certain extent, reduces the occupied area of the wires and cables, can protect the wires and cables, prevents the wires and cables from being corroded, prolongs the service life of the wires and cables, improves the safety of the wires and cables, and ensures the personal safety of people and the normal production of the people. However, the protection tube of the present invention is supported and fixed only by the fixing plates, the distance between the adjacent fixing plates is large, and the protection tube is required to be covered with soil, cement, or the like, and thus, the protection tube with the cable mounted thereon is easily deformed after a long time use, which affects the service life of the protection tube and further the service life of the cable.
The patent with the publication number of CN106921139A discloses a cable supporting and protecting device, which comprises a frame body, wherein the upper surface of the frame body is provided with more than one fiber cement protecting tube, the fiber cement protecting tubes are connected to the frame body in a rolling manner and are internally provided with sealing connecting tubes, the sealing connecting tubes are detachably connected to the fiber cement protecting tubes, the diameters of the threading tubes in the fiber cement protecting tubes are different, the lower surface of the frame body is provided with a supporting plate, two ends of the supporting plate and two sides of the frame body are on the same horizontal line, the supporting plate and the frame body are connected through an adhesive layer, the lower surface of the supporting plate is provided with a protecting plate, and the protecting plate is connected with the supporting plate through detachable screws. However, the support legs of the invention are not beneficial to long-time use of the underground cable, the service life of the cable can be influenced because the underground soil is loose and uneven and the stability of the support legs is influenced, and the invention does not solve the problem of difficult maintenance and construction of the cable.
