Abstract
The present invention relates to a kind of intermediate heat-insulated cable protection pipes of double glazing steel for filling bubble; including fiberglass outer tube body and the fiberglass interior tube body being sheathed on the inside of fiberglass outer tube body; coaxial sleeve is equipped with multiple spacing rings being spaced apart between the fiberglass outer tube body and fiberglass interior tube body; at least one grout hole is offered on each spacing ring; and hard polyurethane foam has also been poured between the fiberglass outer tube body and fiberglass interior tube body, form hard polyurethane foam tube body.The present invention uses double glazing steel tube body structure; fiberglass is not only light and hard, performance is stable, corrosion-resistant; and the thermal conductivity of fiberglass at room temperature is only 1.25~1.67kJ/ (mhK); only the 1/100~1/1000 of metal; it is excellent heat-insulating material; double glazing steel tube body structure can be potent heat-insulated, while being also folded with the excellent polyurethane rigid foam material of heat insulation, can further promote the heat insulation of the cable protection pipe.
Description
Technical field
The present invention relates to the protective device of cable and cable, more particularly to a kind of intermediate double glazing steel for filling bubble every
Electric heating cable protection pipe.
Background technology
Present Construction of Intercity Network and improvement project, Municipal improvement project, Civil Aviation Airport engineering construction, industry park
Area's engineering construction, traffic road and bridge engineering construction, cellular engineering construction etc. are required to carry out power cable, communication cable etc. buried
Laying, to alleviate ground space pressure.Cable is required to add protection sleeve pipe in Exterior cable during buried-pipe laying, rises
To the effect of protection cable, prevents power line from broken string occurs and cause short circuit accident, communication cable and steel wire rope is caused to charge, to protect
Cable, interchanger, machine core board are protected, so that complete machine is not burned, certain buffer action is also functioned to power line magnetic interference.And
Cable may pass through hot environment in laid processes, this just needs protecting pipe to have preferable thermal insulation protection performance.
Invention content
Therefore, for above-mentioned problem, the present invention proposes a kind of intermediate heat-insulated cable protection of double glazing steel for filling bubble
Pipe.
To realize above-mentioned technical problem, the solution that the present invention takes is：A kind of intermediate double glazing steel for filling bubble
Heat-insulated cable protection pipe, including fiberglass outer tube body and the fiberglass interior tube body that is sheathed on the inside of fiberglass outer tube body, described
Coaxial sleeve is equipped with multiple spacing rings being spaced apart between fiberglass outer tube body and fiberglass interior tube body, is opened up on each spacing ring
There is at least one grout hole, and hard polyurethane foam also poured between the fiberglass outer tube body and fiberglass interior tube body,
Form hard polyurethane foam tube body.
It is further improved to be：The thickness of the fiberglass outer tube body is 10.0-30.0mm.
It is further improved to be：The thickness of the fiberglass interior tube body is 8.0-15.0mm.
It is further improved to be：The spacing ring is stainless steel spacing ring.
It is further improved to be：The thickness of the hard polyurethane foam tube body is 5.0-10.0mm.
By using preceding solution, the beneficial effects of the invention are as follows：The present invention uses double glazing steel tube body structure,
Fiberglass is not only light and hard, performance is stable, corrosion-resistant, and the thermal conductivity of fiberglass at room temperature is only 1.25~1.67kJ/
(mhK), only the 1/100~1/1000 of metal, is excellent heat-insulating material, double glazing steel tube body structure can it is potent every
Heat, while it being also folded with the excellent polyurethane rigid foam material of heat insulation, it can further promote the heat-insulated effect of the cable protection pipe
Fruit.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention.
Specific implementation mode
In conjunction with the drawings and specific embodiments, the present invention is further described.
With reference to figure 1, the embodiment of the present invention discloses, a kind of intermediate heat-insulated cable protection of double glazing steel for filling bubble
Pipe, including fiberglass outer tube body 1 and the fiberglass interior tube body 2 for being sheathed on 1 inside of fiberglass outer tube body, in the fiberglass outer tube
Coaxial sleeve is equipped with multiple spacing rings 3 being spaced apart between body 1 and fiberglass interior tube body 2, is offered at least on each spacing ring 3
One grout hole 4, and hard polyurethane foam slurries have also been poured between the fiberglass outer tube body 1 and fiberglass interior tube body 2,
Hard polyurethane foam slurries are full of the interlayer between entire fiberglass outer tube body 1 and fiberglass interior tube body 2 by each grout hole 4,
Cooling and solidifying forms hard polyurethane foam tube body 5 later；
In the present embodiment, the thickness of the fiberglass outer tube body 1 is 16.0mm；
In the present embodiment, the thickness of the fiberglass interior tube body 2 is 8.0mm；
In the present embodiment, the spacing ring 3 uses stainless steel spacing ring, can not only play fixed fiberglass interior tube body 2
Effect, but also the rigidity of the cable protection pipe can be reinforced, prevent it from deforming；
In the present embodiment, the thickness of the hard polyurethane foam tube body 5 is 5.0mm.
By using preceding solution, the beneficial effects of the invention are as follows：The present invention uses double glazing steel tube body structure,
Fiberglass is not only light and hard, performance is stable, corrosion-resistant, and the thermal conductivity of fiberglass at room temperature is only 1.25~1.67kJ/
(mhK), only the 1/100~1/1000 of metal, is excellent heat-insulating material, double glazing steel tube body structure can it is potent every
Heat, while it being also folded with the excellent polyurethane rigid foam material of heat insulation, it can further promote the heat-insulated effect of the cable protection pipe
Fruit.
Although specifically showing and describing the present invention in conjunction with preferred embodiment, the technical solution method and way are implemented
There are many diameter, and the above is only a preferred embodiment of the present invention, but those skilled in the art should be understood that and not depart from
In the spirit and scope of the present invention defined by the appended claims, the present invention can be made in the form and details respectively
Kind variation, is protection scope of the present invention.
