Summary of the invention
Goal of the invention: the purpose of this utility model is in order to overcome deficiency of the prior art; provide a kind of structure arrangement reasonable; easy for installation, can meet the installation requirement of the different cross-sections of cable, waterproof, the novel cable transition joint waterproof anti-explosion protection box that explosion-proof, flameproof effect is good.
Technical scheme: in order to solve the problems of the technologies described above, a kind of novel cable transition joint waterproof anti-explosion protection box described in the utility model, it comprises protection box body, described protection box body has two, be divided into left protection box body and right protection box body, described protection box body is hollow type pyramidal structure, in described protection box body one end, be provided with butt joint edge, the other end is provided with laddering incoming line, described protection box body is from laddering incoming line to the ascending formation pyramidal structure of butt joint edge, on described protection box body, be provided with and let out energy hole or hole for injecting glue, in described protection box body outside, be provided with screw connecting hole.
Described left protection box body and right protection box body, by the docking of butt joint edge left and right, are screwed connection.
On described left protection box body and right protection box body, be respectively provided with one and let out energy hole or hole for injecting glue.
The cross section of described protection box body is circular.
The minimum diameter of described laddering incoming line is 70mm.
Described protection box body is ABS protection box body.
The utility model adopts unique multilayer flashing groove, and ethylene-propylene diene copolymer foaming adhesive tape sealing, guarantees product sealing effectiveness, is applicable under water or severe running environment, prevents cable joint water inlet, guarantees cable reliability service; Good fire resistance: the fire prevention of VO level, can avoid cable joint because of fault burning or blast, combustion and other parallel cables or equipment; Box body upper design has special-purpose pressure release pore, and during operation, through special-purpose lid sealing, the waterproof of cable joint, protection against the tide in the time of both can guaranteeing to move also can be carried out pressure release by assigned direction when cable joint is blasted, and avoid destroying other equipment; Volume is little, lightweight, is convenient for carrying and installs, and is adapted at the narrow space areas such as tunnel, cable trough and installs; Capable of being combined pair of component private cable casting glue used simultaneously, makes this protection box and cable joint become the integral body of a sealing.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model structure arrangement is reasonable, adopt laddering connection jaws, can meet the installation requirement of the different cross-sections of cable, adopt two-part structure, volume is little, lightweight, be convenient for carrying and install, be adapted at tunnel, install in the narrow space areas such as cable trough, by being used in conjunction with private cable casting glue, become the integral body of a sealing, waterproof, explosion-proof, flameproof effect is good, adopt two letting out of upwards laying can hole, can be when cable joint be blasted, by assigned direction, carry out pressure release, avoid destroying other equipment, realistic instructions for use.
Embodiment
Below by drawings and Examples, the utility model is further described.
As shown in Figure 1, a kind of novel cable transition joint waterproof anti-explosion protection box described in the utility model, it comprises protection box body 1, described protection box body 1 has two, be divided into left protection box body 2 and right protection box body 3, described protection box body 1 is hollow type pyramidal structure, in described protection box body 1 one end, be provided with butt joint edge 4, the other end is provided with laddering incoming line 5, described protection box body 1 is from laddering incoming line 5 to the ascending formation pyramidal structure of butt joint edge 4, on described protection box body 1, be provided with and let out energy hole or hole for injecting glue 6, in described protection box body 1 outside, be provided with screw connecting hole 7, described left protection box body 2 and right protection box body 3 dock by butt joint edge 4 left and right, are screwed connection, on described left protection box body 2 and right protection box body 3, be respectively provided with one and let out energy hole or hole for injecting glue 6, the cross section of described protection box body 1 is circular, the minimum diameter of described laddering incoming line 5 is 70mm, described protection box body 1 is ABS protection box body.The utility model structure arrangement is reasonable, adopt laddering connection jaws, can meet the installation requirement of the different cross-sections of cable, adopt two-part structure, volume is little, lightweight, be convenient for carrying and install, be adapted at the narrow space areas such as tunnel, cable trough and install, by being used in conjunction with private cable casting glue, become the integral body of a sealing, waterproof, explosion-proof, flameproof effect good, adopts two letting out of upwards laying can hole, can be when cable joint be blasted, by assigned direction, carry out pressure release, avoid destroying other equipment, realistic instructions for use.
The utility model provides a kind of thinking and method; method and the approach of this technical scheme of specific implementation are a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvements and modifications; these improvements and modifications also should be considered as protection range of the present utility model, in the present embodiment not clear and definite each part all available prior art realized.
