Description
Technical field
The utility model relates to cable intermediate joint protective device, specifically refers to a kind of cable intermediate joint explosive-proof protector box.
Background technology
The transition joint of cable easily because of aging sparking, the short circuit problem such as even blast that produces, causes economic loss even sometimes to threaten personal life security in long-term use.At present, on market, there is multiple cable explosion-proof protection box, comprise iron-clad, fiberglass; although it has certain degree of hardness, heavier, insulativity, fire-retardant degree, anti-impact force, waterproof effect etc. all have deficiency; can cause the sedimentation of cable, and outward appearance is not attractive in appearance.
Certainly also there is the design in portioned product employing blast slowly-releasing hole, comparatively practical.Its operation principle is when the cable intermediate joint generation explosion time that has an accident, if energy is too huge, the blanking cover in blast slowly-releasing hole can be rushed to open energy and be discharged by slowly-releasing hole, thereby reduces the destruction to cable body.But the secondary destruction that the materials such as the high pressure draught that this design is difficult to avoid to eject from slowly-releasing hole, flame, cable fragment produce its adjacent cable being involved.Therefore, we need to set about improving from the structural design of the material selection of protective device and other side the explosive-proof protector performance of product.
Utility model content
In order to overcome above-mentioned deficiency of the prior art; the utility model provides a kind of novel cable transition joint explosive-proof protector box; it is for cable intermediate joint common potential safety hazard and designing in installing and using; there is explosion-proof, waterproof, fire prevention, anticorrosion, solve the premium properties such as temperature rise and long-life.
The utility model solves the technical scheme that its technical problem adopts:
A kind of cable intermediate joint explosive-proof protector box; comprise that two can dock, be semi-cylindrical housing; its two ends of described housing are provided with necking part; described necking part offers for the through hole through cable; the equal correspondence in described housing stage casing and two ends is provided with some binding grooves, and it is fixed by the dead ring docking that is positioned at described binding groove, is provided with anti-flaming thermal-insulation layer between described housing and cable; its inwall of described through hole is grooving shape, is provided with sealing ring in it.
As the improvement of technique scheme, described sealing ring is the semicircular rings that can dock, and its interface is respectively arranged with projection, recess, and its surface is provided with the grooving corresponding with described through-hole wall.
Further, after described sealing ring docking, its end face is provided with silicic acid rubber cushion.
As the improvement of technique scheme, its interface of described housing is provided with sealing strip.
As the improvement of technique scheme, described dead ring is the semicircular rings that can dock, and its two ends offer docking port, and it can be fixed in described binding groove by screw or other fixed structures.
As the improvement of technique scheme, in described housing, be provided with attemperating unit, solve targetedly the problem of temperature rise of armored cassette the inside completely, guarantee that the material capability in whole box is stable, extend the life-span of armored cassette.
The beneficial effect that the utility model brings has:
The utility model is closely fixing by housing by dead ring, anti-flaming thermal-insulation layer is set between housing and cable, in through hole, sealing ring is set simultaneously, cable intermediate joint is sealed in protection box completely, in the time having accident to occur to produce fire, thereby make its condition that does not possess burning can reach flameproof effect because oxygen concentration is limited, due to firm fixed structure, this product also has powerful external force resistance characteristic, when the cable joint generation explosion time that has an accident, armored cassette can be limited in electric cable explosion fragment in armored cassette, thereby avoid the expansion of accident, avoid the generation of cable body and secondary destruction in cable fault, in addition, the utility model possesses comprehensive water resistance, avoid it to soak and cause the reduction of profile and fire-proof and explosion-proof performance because of humidity.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail,
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structure explosive views of the present utility model;
Accompanying drawing 3 is dead ring structural representations of the present utility model;
Accompanying drawing 4 is seal ring structure schematic diagrames of the present utility model.
Embodiment
With reference to accompanying drawing 1 to accompanying drawing 4; cable intermediate joint explosive-proof protector box of the present utility model; comprise that two can dock, be semi-cylindrical housing 1; the two ends of housing 1 are provided with necking part 11; simultaneously all corresponding binding grooves 12 that is provided with of housing 1 stage casing and two ends, fixing by being positioned at dead ring 2 docking of this binding groove 12, this protective device can complete firm substantially fixing; in order to ensure its sealing property, housing 1 its interface in the time of docking is also provided with sealing strip 13.
Other, above-mentioned necking part 11 offers for the through hole through cable, its inwall of through hole is grooving shape, is provided with sealing ring 3 in it, in order to install further sealing effectiveness, sealing ring 3 is designed to the semicircular rings that can dock, and its interface is respectively arranged with projection 31, recess 32, and its surface is provided with the grooving corresponding with through-hole wall, it can be fixed with the perfect sealing of through hole, sealing ring 3 its end face after docking is also provided with silicic acid rubber cushion, can bring into play better water-tight effect.Simultaneously above-mentioned dead ring 2 is also designed to the semicircular rings that can dock, and its two ends offer docking port 21, can be fixed in by screw or other fixed structures that binding groove 12 is interior to be fixed housing 1 when use.
Therefore product of the present utility model can be sealed in cable intermediate joint in protection box completely; make cable intermediate joint in a complete airtight environment; in addition it configures high-performance refractory thermal insulation layer between housing 1 and cable; in the time having accident to occur to produce fire, thereby due to the limited effect that makes its condition that does not possess burning can reach fire-retardant fireproof of the interior oxygen concentration of housing 1.
Because this product mainly sets about improving the capability of antidetonance of device from the structural design of material and other side, so in selection, this product adopts high composite materials to develop, above-mentioned housing 1, sealing ring 3 and sealing strip 13 all adopt high composite materials, its material rate is one-level, brings the features such as resisting strong impact, high flame retardant, high-insulativity, anticorrosion, long-life for this device.Based on this powerful external force resistance characteristic, when the cable intermediate joint generation explosion time that has an accident, explosive-proof protector box can limit electric cable explosion fragment therein, thereby has avoided the expansion of accident, and the harm of accident is weakened greatly.
