Abstract
The utility model discloses a fireproof groove box for cables, and especially relates to a fireproof groove box which facilitates heat dissipation of the cables. The fireproof groove box comprises an outer groove body, an inner groove body, alumina silicate cotton filled between the outer groove body and the inner groove body, and a cover plate sealed on upper portions of the outer groove body and the inner groove body; the cover plate comprises an internal layer cover plate, a middle layer cover plate and an external layer cover plate; the external layer cover plate is provided with an upwardly protruded intermediate cover plate and an edge cover plate for connecting the intermediate cover plate; the middle layer cover plate is positioned in a cavity enclosed by the intermediate cover plate and the edge cover plate, and the middle layer cover plate is fixedly connected with inner walls of the cavity; the internal layer cover plate is fixedly connected with the edge cover plate; and a part of the internal layer cover plate is provided with a waist hole, a part, corresponding to the waist hole position, of the middle layer cover plate is provided with an upwardly protruded projection, and the projection is provided with a radiating hole. The three-layer cover plate is disposed for the fireproof groove box, and heat of the cables can be dissipated by utilization of the waist hole in the internal layer cover plate and the radiating hole in the projection of the middle layer cover plate. Fireproof materials coated on the radiating hole expand and obstruct the radiating hole when a fire happens, so that the cables are protected.
Description
Technical field
The utility model discloses fire-resistant cable slot box, be especially conducive to the fire-resistant cable slot box of large load power cable heat radiation.
Background technology
At present, the fire-resistant groove box (being again fire-retardant bridge) on market is mainly comprised of metallic framework and fiber glass reinforcement, the composite fireproof plate of inorganic material, fire-resistant aluminium silicate wool felt and fire prevention base foamed coating.And most manufacturing enterprise only focuses on the fire resistance of crane span structure, ignored its practical service environment.The crane span structure majority of this type is for there being the power cable that fire-fighting requires to lay, this cable load is large, produce heat also relatively many, and how effectively first the design concept of fire-retardant bridge be exactly emphasis fire-proof and thermal-insulation, this has just produced contradiction, the dissipation of heat of cable is not gone out, and will make to move under its hot soak condition, has just accelerated the aging of cable yet.
Utility model content
Technical problem to be solved in the utility model is the deficiency for above-mentioned background technology, and exhausting heat radiation type fire-resistant cable slot box is provided.
The utility model adopts following technical scheme for realizing above-mentioned utility model object:
Fire-resistant cable slot box, comprises outer cell body, interior cell body, is filled in the aluminium silicate wool between outer cell body and interior cell body, is sealed in the cover plate of outer cell body, interior cell 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 swelling and the edge cover plate that connects described inter panel, described middle level cover plate is positioned at the 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 part has waist hole, the projection that the part that middle level cover plate is corresponding with waist hole site is the protuberance that makes progress, described projection has louvre.
Further, the louvre of fire-resistant cable slot box outside scribbles fireproof paint.
Further, in fire-resistant cable slot box, internal layer cover plate, interior cell body are made by 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, is fixed with earth stud on the external wall of water jacket.
The utility model adopts technique scheme, there is following beneficial effect: the principle that the utility model utilizes heat upwards to distribute, by three layers of cover plate are set, utilize the waist hole of internal layer fire prevention cover plate and the louvre on the cover plate projection of middle level, cable heat is shed.The louvre that scribbles fire proofing material expands and blocks louvre when running into fiery residence, has protected cable.
Accompanying drawing explanation
Fig. 1 is fire-resistant cable slot box.
Embodiment
Below in conjunction with accompanying drawing, the technical scheme of utility model is elaborated:
Specific embodiment one: as shown in Figure 1, fire-resistant cable slot box, comprises outer cell body, interior cell body, is filled in the aluminium silicate wool between outer cell body and interior cell body, is sealed in the cover plate on outer cell body, interior cell body top.Cover plate comprises internal layer cover plate, middle level cover plate, outer cover plate.Outer cover plate has upwards the inter panel of protuberance and the edge cover plate that connects inter panel, and middle level cover plate is positioned at the cavity that inter panel surrounds with edge cover plate and is fixedly connected with cavity inner wall, and internal layer cover plate is fixedly connected with edge cover plate.Internal layer cover plate part has waist hole, the projection that the part that middle level cover plate is corresponding with waist hole site is the protuberance that makes progress, and projection has louvre.
The principle of utilizing heat upwards to distribute, opens waist hole in internal layer cover plate part, and on the cover plate of middle level, the part corresponding with waist hole has louvre for upwards swelling projection, and louvre is positioned in dissipation of heat direction, is conducive to the heat of cable to shed.
Specific embodiment two: on the basis of specific embodiment one, scribble fireproof paint in louvre, fireproof paint expands and blocks louvre when running into fiery residence, has protected cable.Outer cover plate is forming the upwards inter panel of protuberance through a cold roll forming with projection correspondence position, and the cavity forming between inter panel and edge cover plate is conducive to shedding of cable heat, simultaneously because a cold roll forming has guaranteed seal.
In addition, in specific embodiment one and specific embodiment two, internal layer cover plate, interior cell body are made by inorganic fireproof material, and middle level cover plate, outer cover plate are steel cover plate.On the external wall of water jacket, be fixed with earth stud.Preferred square waist hole, waist hole.
The fire-resistant heat dispersion of fire-resistant cable slot box, through A level (950-1000 ℃) fire resistance test of national fixed fire extinguishing system and fire retarding component Quality Supervision and Inspection Center, reaches 75 minutes conduction time, and groove box inner cable is not damaged still.Tested the overall structure that groove box supports intact, fixed inorganic fire prevention channel box inner bag effectively, thus guarantee the normal power supply of fire-fighting equipment cable under fire condition..
In sum, fire-resistant cable slot box described in the utility model, the principle of utilizing heat upwards to distribute, by three layers of cover plate are set, utilizes the waist hole of internal layer cover plate and the louvre on the cover plate projection of middle level, and cable heat is shed.The louvre that scribbles fire proofing material expands and blocks louvre when running into fiery residence, has protected cable.
