Abstract
The invention discloses a fireproof cable trough box, and particularly provides a fireproof cable trough box which facilitates heat radiation of a cable. The fireproof cable trough box comprises an outer trough body, an inner trough body, aluminum silicate wool and a cover plate, wherein the aluminum silicate wool is filled into the position between the outer trough body and the inner trough body, and the cover plate is sealed on the upper portion of the outer trough body and the upper portion of the inner trough body. The cover plate comprises an inner layer cover plate body, a middle layer cover plate body and an outer layer cover plate body. The outer layer cover plate body is provided with a middle cove plate and an edge cover plate, wherein the middle cover plate protrudes upwards, and the edge cover plate is connected with the middle cover plate. The middle layer cover plate body is located in a cavity and fixedly connected with the inner wall of the cavity, wherein the cavity is defined by the middle cover plate and the edge cover plate. The inner layer cover plate body is fixedly connected with the edge cover plate. A kidney-shaped hole is formed in local position of the inner layer cover plate body. Lugs which protrude upwards are arranged at the local position, corresponding to the position of the kidney-shaped hole, of the middle layer cover plate body. Heat radiating holes are formed in the lugs. By the arrangement of the three layer cover plates, heat of the cable is radiated through the kidney-shaped hole in the inner layer cover plate body and the heat radiating holes in the lugs of the middle layer cover plate body. The heat radiating holes coated with fireproof material expand and are blocked when fires occur, and therefore the cable is protected.
Description
Technical field
The invention 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.
Summary of the invention
Technical problem to be solved by this invention is the deficiency for above-mentioned background technology, and exhausting heat radiation type fire-resistant cable slot box is provided.
The present invention adopts following technical scheme for achieving the above 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 present invention adopts technique scheme, has following beneficial effect: the principle that the present invention 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, and 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.Number in the figure explanation: 1, outer cell body, 2, interior cell body, 3, aluminium silicate wool, 4, internal layer cover plate, 5, middle level cover plate, 6, outer cover plate, 7, louvre, 8, earth stud.
Embodiment
Below in conjunction with accompanying drawing, the technical scheme of invention is elaborated:
Specific embodiment one: as shown in Figure 1, fire-resistant cable slot box, comprises outer cell body 1, interior cell body 2, is filled in the aluminium silicate wool 3 between outer cell body 1 and interior cell body 2, is sealed in the cover plate on outer cell body 1, interior cell body 2 tops.Cover plate comprises internal layer cover plate 4, middle level cover plate 5, outer cover plate 6.Outer cover plate 6 has upwards the inter panel of protuberance and the edge cover plate that connects inter panel, and middle level cover plate 5 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 4 is fixedly connected with edge cover plate.Internal layer cover plate 4 parts have waist hole, the projection that the part that middle level cover plate 5 is corresponding with waist hole site is the protuberance that makes progress, and projection has louvre 7.
The principle of utilizing heat upwards to distribute, opens part corresponding with waist hole on the cover plate of ， middle level, waist hole and has louvre for upwards swelling projection in internal layer cover plate part, 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 4, interior cell body 2 are made by inorganic fireproof material, and middle level cover plate 5, outer cover plate 6 are steel cover plate.On outer cell body 1 outer wall, be 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 ℃) fire resistance test at national fixed fire extinguishing system and fire retarding component quality supervision and test 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 of the present invention, 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.
