Description
Technical Field
The invention belongs to the technical field of cable joint protection devices, and particularly relates to a detachable explosion-proof device for an underground cable joint.
Background
The above-mentioned underground cable refers to a cable provided in an underground pipe gallery, and the aforementioned detachable explosion-proof device is an additional protection device for a cable joint provided outside the cable joint. The structure of the cable splice and its function are well known in the art and are visible in the published chinese patent literature, such as the "a new cable intermediate splice explosion protection device" recommended by CN105576596B and the "a high voltage cable intermediate splice fire and explosion protection device" provided by CN106786329a, etc.
As known in the art, a cable joint (also referred to as a "cable intermediate joint", hereinafter, the same) is the weakest part of a cable, and a cable joint is inevitably used in a power system, a thermal power plant, a nuclear power plant, a hydroelectric power plant, a petrochemical industry, and the like in using the cable. The large section cable is calculated in units of reels, if the unwinding (unwinding) length (total length) of the reels is 500 meters, there is one cable connector every 500 meters.
In recent years, urban power supply cables are being developed toward the erection of underground pipe galleries, that is, cables are being erected on gallery walls of underground pipe galleries, and as the amount of electricity used increases, cables are required to be added in the underground pipe galleries, thus involving a problem of construction safety. Because the original cable is in the power supply state continuously in the construction process of the frame-added cable, and because the cable joint is the weakest area (namely the part) of the cable as described above, once combustible gas or combustible liquid leaks in the underground pipe gallery construction area, the combustible gas or combustible liquid is ignited through high temperature or open fire, and cable fire and explosion are extremely easy to occur. In addition, if dust is seriously raised in the construction area of the underground pipe gallery or sundries are piled up and touch the cable joints, or limbs and tools of constructors touch the cable joints, cable fire and explosion can exist. Protection of the cable joint of a cable previously laid and in an operating state (energized state) is therefore necessary during additional cabling.
Technical information for additional protection of cable connectors is known in the published chinese patent literature, typically a "cable intermediate connector explosion-proof protection box" as introduced in CN103633610a, which is composed of two semi-cylindrical shells that can be butted together, a neck is formed at each of two ends of the two semi-cylindrical shells, fastening grooves are provided at intervals in the middle sections of the two shells, fastening rings are provided in the fastening grooves, and when in use, the cable intermediate connector is shielded by the two shells, and the two shells are fixed by the fastening rings. Although the technical effect described in the 0012 section of the specification can be reflected to a certain extent, the following disadvantages exist in the structure of the patent: firstly, because the shell is of a two-flap structure, the two shells are matched with each other by virtue of a plurality of semi-annular fastening rings, and each pair of fastening rings is connected with each other by virtue of two fasteners such as screws, the two shells are troublesome to manufacture and install and the installation efficiency is low; secondly, because the number of parts is large and the parts are independent, the repeated disassembly and the use are inconvenient, and because after the operation of additionally erecting the cable in one area of the pipe gallery is completed, when a constructor transfers to another area, if the explosion-proof device temporarily arranged on the original cable connector in the certain area can be disassembled and transferred to the original cable connector in the other area, the double functions of saving resources and guaranteeing the safety of the constructor can be achieved; thirdly, since cable holders are generally provided on the corridor wall of the underground pipe corridor in a horizontally cantilever state at positions corresponding to both ends of the cable connector, both end portions of the cable connector are supported by the cable holders, and damage to the cable due to occurrence of deflection deformation is avoided, so that the two housings proposed in the patent interfere with the cable holders. Also, CN10496708B announces that "an integral high-voltage cable explosion-proof joint box", which can objectively honor the advantages described in paragraphs 0022 to 0029 of the specification, but has no borrowable meaning for temporarily protecting the cable joints of the original cables when additional cabling work is performed in the underground piping lane because of its non-detachable mobility.
The applicant has advantageously explored and devised and developed the solution described below with respect to the prior art.
