Abstract
The utility model discloses a kind of cable explosion-proof box having from fire-extinguishing function concurrently, including shell and fire extinguishing item, the shell have wave structure in the axial direction；The fire extinguishing item includes magnesium oxide particle and nitrile rubber clad, and nitrile rubber clad is hollow tubular structure, closed at both ends, and magnesium oxide particle is filled with inside nitrile rubber clad；The fire extinguishing item is bonded in case inside recess by binder, and the fire extinguishing item is completely attached to shell inner recess and contact portion is bonded by binder；The cable explosion-proof box shell has wave structure, also has fire extinguishing item on the inside of armored cassette, and when explosion time occurs for cable connector, the shell of wave structure is deformable to be stretched, and fire extinguishing item rupture, a fire extinguishing internal oxidation magnesium granules spread out, play the role of from fire extinguishing.
Description
Technical field
The utility model belongs to field of cable technology, specifically a kind of cable explosion-proof box having from fire-extinguishing function concurrently.
Background technology
Cable often needs to two cables being attached when being laid with, and the tie point of two cables is known as cable connector,
Since cable is layed in underground more, cable connector is easy to aging in the long-term use, may lead to sparking, short circuit, when serious
It can explode, after cable connector explodes at one, by other cables on fire that ignite, cause second accident, so, cable
Joint is all made of cable explosion-proof box, and cable connector is placed in armored cassette, prevents at cable connector the intensity of a fire after explosion on fire
Other cables are spread to, existing cable explosion-proof box is mostly by the sealing performance for the armored cassette that explodes, after on fire, due to explosion-proof
In box amount of oxygen it is limited and can not sustained combustion, but since explosion-proof box seal tape contact line road is long, contact area is big, can not ensure
Band can be fitted and connected portion completely everywhere, poor sealing performance, and if cable connector explode, armored cassette can be caused to deform,
It can not more ensure the sealing performance of armored cassette, to which the sprawling of the cable connector rear intensity of a fire on fire from explosion can not be prevented.
Invention content
Goal of the invention：The purpose of this utility model is provided a kind of with fire extinguishing work(certainly for the deficiency in current technology
The cable explosion-proof box of energy, the cable explosion-proof box shell have wave structure, also have fire extinguishing item on the inside of armored cassette, when cable connects
Hair gives birth to explosion time, and the shell of wave structure is deformable to be stretched, and fire extinguishing item rupture, a fire extinguishing internal oxidation magnesium granules spread out, rise
It is acted on to from fire extinguishing.
Technical solution：To achieve the above object, the utility model provides a kind of cable explosion-proof box having from fire-extinguishing function concurrently,
Including shell and fire extinguishing item, the shell has wave structure in the axial direction；The fire extinguishing item includes magnesium oxide particle and fourth
Fine rubber adhesive, nitrile rubber clad is hollow tubular structure, closed at both ends, and filling is aerobic inside nitrile rubber clad
Change magnesium granules；The fire extinguishing item is bonded in case inside recess, the fire extinguishing item and shell inner recess by binder
It completely attaches to and contact portion is bonded by binder.
Further, the magnesium oxide particle size is 0.1-1mm.Further, the armouring unit is pps material systems
At.
Advantageous effect：A kind of cable explosion-proof box having from fire-extinguishing function concurrently described in the utility model, the cable explosion-proof
Box shell has wave structure, and when explosion time occurs for cable connector, the shell, which has deformed upon, causes wave structure region flat
Sliding curved-surface structure prevents casing rupture to absorb part explosion energy, while sunk part is gone back on the inside of armored cassette with fire extinguishing
Item, armored cassette wave structure are stretched to during smooth surface, and sunk part radian increased dramatically, due to fireproof strip and recess
Part completely attaches to and bonds, and the shell that nitrile rubber clad is deformed on item of putting out a fire is pullled, while exploding in cable connector
Under force effect, nitrile rubber clad rupture on item of putting out a fire, a fire extinguishing internal oxidation magnesium granules are spread out, and the magnesium oxide particle is
A kind of fire retardant, when burning, need to consume amount of heat and generate water, make burning be difficult to continue, play the role of fire extinguishing.
A kind of cable explosion-proof box having from fire-extinguishing function concurrently, has from fire-extinguishing function concurrently, in use, when interior
After portion's cable connector explodes, magnesium oxide particle can be released automatically and put out a fire, prevent fire spreading, flameproof effect of putting out a fire
It is prominent, while the cable explosion-proof box is simple in structure, it is of low cost, it is easy to promote the use of on a large scale.
