Description
Technical field
The present invention discloses fire-resistant cable slot box, is especially conducive to the fire-resistant cable slot box that big load power cable dispels the heat.
Background technology
At present, the fire-resistant groove box (being again fire-retardant bridge) on market is primarily of metallic framework and glass fibre reinforcement, the composite fire-proof plate of inorganic materials, fire-resistant aluminium silicate wool felt and fire prevention base foamed coating composition. And the manufacturing enterprise of major part only focuses on the fire performance of crane span structure, have ignored its practical service environment. The crane span structure majority of this type is for there being the power cable of fire-fighting requirements to lay, this cable load is big, produce heat also relatively many, and how effectively first the design theory of fire-retardant bridge be exactly emphasis fire-proof and thermal-insulation, this generates contradiction, the heat of cable does not distribute not go out, and runs, just accelerate the aging of cable yet under it will be made to be in the condition of high temperature for a long time.
Summary of the invention
Technical problem to be solved by this invention is the deficiency for above-mentioned background technology, it provides exhausting heat radiation type fire-resistant cable slot box.
The present invention adopts following technical scheme for achieving the above object:
Fire-resistant cable slot box, comprises outer groove body, inside groove body, the aluminium silicate wool being filled between outer groove body and inside groove body, is sealed in the cover plate of outer groove body, inside groove body upper opening portion, and described cover plate comprises internal layer cover plate, middle level cover plate, outer cover plate,
Described outer cover plate has the inter panel upwards swelled and connects the edge cover plate of described inter panel, described middle level cover plate is positioned at cavity that inter panel surrounds with edge cover plate and is fixedly connected with cavity inner wall, described internal layer cover plate is fixedly connected with edge cover plate
Wherein: internal layer cover plate local has waist hole, and the local that middle level cover plate is corresponding with waist hole site is the projection upwards swelled, described projection has heat radiation hole.
Further, scribble fireproof coating outside the heat radiation hole of fire-resistant cable slot box.
Further, in fire-resistant cable slot box, internal layer cover plate, inside groove body are made up of inorganic fireproof material.
Further, in fire-resistant cable slot box, middle level cover plate, outer cover plate are steel cover plate.
Further, fire-resistant cable slot box, waist hole is square waist hole.
Further, fire-resistant cable slot box, the external wall of outer groove is fixed with earth stud.
The present invention adopts technique scheme, has following useful effect: the principle that the present invention utilizes heat upwards to distribute, and by arranging three layers of cover plate, utilizes the heat radiation hole on the waist hole of internal layer fireproof cover plate and middle level cover plate projection so that cable heat falls apart. Scribble expansion blocks heat dissipation hole when running into fire residence, heat radiation hole of fire-retardant material, protect cable.
Accompanying drawing explanation
Fig. 1 is fire-resistant cable slot box. Number in the figure illustrates: 1, outer groove body, 2, inside groove body, 3, aluminium silicate wool, 4, internal layer cover plate, 5, middle level cover plate, 6, outer cover plate, 7, heat radiation hole, 8, earth stud.
Embodiment
Below in conjunction with accompanying drawing, the technical scheme of invention is described in detail:
Specific embodiment one: as shown in Figure 1, fire-resistant cable slot box, comprises outer groove body 1, inside groove body 2, the aluminium silicate wool 3 being filled between outer groove body 1 and inside groove body 2, is sealed in the cover plate on outer groove body 1, inside groove body 2 top. Cover plate comprises internal layer cover plate 4, middle level cover plate 5, outer cover plate 6. Outer cover plate 6 has the inter panel upwards swelled and connects the edge cover plate of inter panel, and middle level cover plate 5 is positioned at cavity that inter panel surrounds with edge cover plate and is fixedly connected with cavity inner wall, and internal layer cover plate 4 is fixedly connected with edge cover plate. Internal layer cover plate 4 local has waist hole, and the local that middle level cover plate 5 is corresponding with waist hole site is the projection upwards swelled, and projection has heat radiation hole 7.
Utilizing the principle that heat upwards distributes, open waist hole in internal layer cover plate local, local corresponding with waist hole on the cover plate of middle level is that upwards protuberance projection has heat radiation hole, and heat radiation hole is positioned at heat and distributes on direction, is conducive to faling apart by the heat of cable.
Specific embodiment two: on the basis of specific embodiment one, heat radiation scribbles fireproof coating in hole, and fireproof coating is expansion blocks heat dissipation hole when running into fire residence, protects cable. Outer cover plate is forming, through a cold roll forming, the inter panel upwards swelled with projection correspondence position, the cavity formed between inter panel and edge cover plate be conducive to cable heat loose go out, simultaneously because a cold roll forming ensure that stopping property.
In addition, in specific embodiment one and specific embodiment two, internal layer cover plate 4, inside groove body 2 are made up of inorganic fireproof material, and middle level cover plate 5, outer cover plate 6 are steel cover plate. Outer groove body 1 outer wall is fixed with earth stud 8. Preferred square waist hole, waist hole.
The fire-resistant heat dispersion of fire-resistant cable slot box, through A level (950-1000 DEG C) fire testing of country's fixed fire extinguishing system and fire retarding component Quality Supervision and Inspection Center, reaches 75 minutes conduction time, groove box inner cable still not damaged. Tested the overall structure that groove box supports intact, can courage in fixed inorganic fire prevention channel box effectively, so that it is guaranteed that the normal power supply of fire-fighting equipment cable under fire condition..
In sum, fire-resistant cable slot box of the present invention, utilizes the principle that heat upwards distributes, and by arranging three layers of cover plate, utilizes the heat radiation hole on the waist hole of internal layer cover plate and middle level cover plate projection so that cable heat falls apart. Scribble expansion blocks heat dissipation hole when running into fire residence, heat radiation hole of fire-retardant material, protect cable.
