Abstract
The invention relates to a fully-sealed grouting waterproof, fireproof and explosion-proof safety box for a cable middle joint, which comprises a casing made from a weak magnet board synthetic material and an inner casing for the explosion-proof box formed by grouting epoxy resin, wherein, the casing integrally forms a cylinder by two semi-cylindrical shells connected through a reserved bolt hole; a silicon rubber sealing gasket layer is arranged on the joint face of the two semi-cylindrical shells; the two semi-cylindrical shells of the casing are connected together through explosion-proof hexagon socket set screws with cup points; and the diameter of two ends of the casing is reduced so that two ends can form a tightening mouth, and a small-sized cylindrical section is formed at the tightening mouth. The safety box of the invention has the beneficial effects as follows: the casing is integrally subject to one-time forming without welding, hot dipping and demagnetizing treatment and spraying of an anticorrosive uvioresistant material, thus achieving strong anti-explosion ability, strong corrosion resistance and long ageing-resistant time; the casing has common stretchability; the casing is melted into a carbonized shape or severely deformed after long-time combustion; and the adopted fireproof, flame-retardant and heat-insulating layer has fireproof, flame-retardant and heat-insulating effects.
Description
Technical field
The present invention relates to a kind of hermetically sealed pouring formula cable intermediate joint waterproof fireproofing anti-explosion safety box.
Background technology
Well-known anti-explosion product housing main material iron plate or steel plate, and the product body must reach sealing; So-called explosion-proof being meant under hermetic situation just can be played explosion-proof.Hermetically sealed because of oxygen, air are arranged because if cable does not have when producing spark, thus just can produce fire, and then blast.If therefore anti-explosion product fails to accomplish must not reach explosion-proof effect under the hermetic situation.And we select for use the cable armored cassette will arrive expected effect, and reason can reduce five kinds of situations: 1, electric cable accessories quality problems; 2, cable quality problem (as when the payout, cable sheath damage and water inflow or cable are put back sealing cap useless well it is sealed, and cable in wet condition); 3, electric cable accessories mounting process problem; 4, running environment problem; 5, overload operation, the too high problems of excessive heat of temperature of cable junction; Our cable mid head majority is to move in cable trough or cable shaft, so taking place, a lot of accidents influenced by running environment, at least account for a greater part of factor, move in water because of often steeping, make moist, advance situations such as air, take place then that cable end punctures, spontaneous combustion, more serious after blast other cable also being wound blown up even burnt.Move in water if the armored cassette of usefulness is the hermetic frequent bubble of cable mid head of just can avoiding, make moist, advance situations such as air, lower the probability that has an accident, avoid when having an accident, loss being dropped to minimum.
Summary of the invention
For addressing the above problem, it is long to the invention provides strong, the ageing-resistant time of a kind of antiknock power and corrosion resistance, can play the hermetically sealed pouring formula cable intermediate joint waterproof fireproofing anti-explosion safety box of sealing, waterproof action.
The objective of the invention is to be achieved through the following technical solutions:
Hermetically sealed pouring formula cable intermediate joint waterproof fireproofing anti-explosion safety box of the present invention, comprise that housing and epoxy resin by the manufacturing of weak magnet plate synthetic material water the armored cassette inner casing that forms, housing integral body is connected to become a cylinder by two semicolumn housings by the bolt hole of reserving, be provided with one deck silicone rubber seal pad at two semicolumn housing joint face places, two semicolumn housings of housing are connected by the recessed end screw of hexagonal in explosion-proof, inner walls is with the silicone rubber seal bed course with the heat insulation effect of fire protection flame retarding, housing outer surface is coated with anticorrosion uvioresistant powder, the diameter at the housing two ends formation tightening mouth that diminishes, and form one section small size at the tightening mouth place cylindrical.
As the further improvement of invention, the inside of described tightening mouth is equipped with silicone rubber O-ring.
As the further improvement of invention, described several fixedly circle bodies of fire proof heat-insulation layer that in housing, is provided with, the central authorities of circle body have aperture and pass through for inner casing.
Beneficial effect of the present invention is: housing overall time of the present invention does not have the shape of being welded into, and is whole through hot dip, demagnetization processing, the anticorrosion ultraviolet ray-resistant material of whole plastic-blasting; Strong, the ageing-resistant time of antiknock power and corrosion resistance is long.Housing has more general draftability, and housing has antiknock power, but relatively poor; Burning is fused into carbonization shape or gross distortion for a long time.The fire protection flame retarding thermal insulation layer can play fire protection flame retarding, heat-blocking action.Anticorrosion uvioresistant powder is used in can play fire prevention, fire retardation preferably for a long time in the armored cassette product.Waterproof sealing annex colloid is better, and is soft, can play sealing, waterproof action.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structure chart of the described hermetically sealed pouring formula cable intermediate joint waterproof fireproofing anti-explosion safety box of the embodiment of the invention.
Fig. 2 is an A-A cross-sectional view among Fig. 1;
Fig. 3 is a B-B cross-sectional view among Fig. 1.
Embodiment
As Figure 1-3, hermetically sealed pouring formula cable intermediate joint waterproof fireproofing anti-explosion safety box of the present invention, comprise that housing 1 and epoxy resin by the manufacturing of weak magnet plate synthetic material water the armored cassette inner casing 2 that forms, housing 1 integral body is connected to become a cylinder by two semicolumn housings by the bolt hole of reserving, be provided with one deck silicone rubber seal pad 7 at two semicolumn housing joint face places, two semicolumn housings of housing are connected by the recessed end screw of hexagonal in explosion-proof, the diameter at housing two ends diminishes and forms tightening mouth 5, and it is cylindrical in tightening mouth 5 places one section small size of formation, the inside of tightening mouth 5 is equipped with silicone rubber O-ring 3, housing 1 inwall is with the silicone rubber seal bed course 6 with the heat insulation effect of fire protection flame retarding, housing 1 outer surface is coated with anticorrosion uvioresistant powder, be provided with several fixedly circle bodies 4 of fire proof heat-insulation layer in housing, the central authorities of circle body 4 have aperture and pass through for inner casing.
Among the present invention, the housing overall time does not have the shape of being welded into, and is whole through hot dip, demagnetization processing, the anticorrosion ultraviolet ray-resistant material of whole plastic-blasting; Strong, the ageing-resistant time of antiknock power and corrosion resistance is long.Housing has more general draftability, and housing has antiknock power, but relatively poor; Burning is fused into carbonization shape or gross distortion for a long time.The fire protection flame retarding thermal insulation layer can play fire protection flame retarding, heat-blocking action.Anticorrosion uvioresistant powder is used in can play fire prevention, fire retardation preferably for a long time in the armored cassette product.Waterproof sealing annex colloid is better, and is soft, can play sealing, waterproof action.
