The utility model discloses a two semicircular cover bodies that the ability lock is in the same place, the semicircular cover body adopts flameresistant material to make, and the two semicircular cover body is through bolted connection, the interior wall energy of the two semicircular cover body and the outer wall laminating of cable. The utility model discloses can block the cable burning, prevent flame spread, reduce life loss of property.
Description
Technical field
The utility model relates to electric power conveying technology field, specifically a kind of cable-flame retardant cover.
Background technology
Along with the development in city, urban skyscraper gets more and more, and for guaranteeing the safety of city dweller's person, family's property, the Electrical Safety of skyscraper and fireproofing are particularly important.Because the cable of skyscraper cable shaft is once catch fire, will form stack effect, developing fire is exceedingly fast, and works the mischief to cable used, fault spread, causes difficulty to repairing afterwards.And in recent years, also repeatedly there is high-rise building power supply ignition of cable accident, one place's ignition of cable and spread cause multi-layer cable catch fire, many or whole piece cable is caused to be scrapped, greater loss is caused to the property of company and city dweller, because fault intractability is comparatively large, causes and can not recover residential electricity consumption in time, had a strong impact on power supply quality and electricity sales amount.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of cable-flame retardant cover, can block cable fire, prevent propagation of flame, reduces life and property loss.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of cable-flame retardant cover, comprise two semicircle cover bodies that can snap together, semicircle cover body adopts fire proofing to make, two halves circular cover body is bolted, and the interior wall energy of two halves circular cover body and the outer wall of cable are fitted.
Further technical scheme, semicircle cover body comprises and is positioned at middle large semicircle and is divided into large semicircle two ends and integrally formed with it two small semicircles, after these two semicircle cover bodies fasten, in the middle of it, form cavity, the interior wall energy of the small semicircle at two ends and the outer wall of cable closely connected.
Further technical scheme, the position fastened at two halves circular cover body is also provided with fire-retardant sealing gasket.
The beneficial effect adopting technique scheme to produce is: the utility model is arranged on the appearance of cable, the intensity of a fire can be stoped along cable propagating combustion, what block the intensity of a fire spreads approach, reduces causality loss, is applicable to vertical run ignition of cable blocking-up in cable shaft in skyscraper.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of single semicircle cover body in Fig. 1;
In figure: 1, semicircle cover body.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Along with the development in city, urban skyscraper gets more and more, and for guaranteeing the safety of city dweller's person, family's property, the Electrical Safety of skyscraper and fireproofing are particularly important.Because the cable of cable shaft is once catch fire, will form stack effect, developing fire is exceedingly fast, and works the mischief to cable used, fault spread, causes difficulty to repairing afterwards.Potential safety hazard is without minor matter, and the Mars of a little or artificial general idea and carelessness, all likely lead to large accident, cause great casualties and property loss, lesson is deep.Therefore, for the fire in high buildings problem day by day highlighted, safeguard measure is carried out to the cable in lift well and is necessary.The utility model installs a fire-retardant cover at the outer wall of cable additional every a segment distance, will form an insulating course in physics, the intensity of a fire spread reduced gradually and controlled after several fire-retardant cover along cable, and then the control of fire at minimum zone.
The utility model specifically comprises two semicircle cover bodies 1 that can snap together, and semicircle cover body 1 adopts fire proofing to make, and two halves circular cover body 1 is bolted, and the interior wall energy of two halves circular cover body 1 and the outer wall of cable are fitted.Fire proofing is material well known in the prior art, extensive use, such as various fire retardant, flame-retardant board, flame retardant rubber etc.Also can adopt at semicircle cover body 1 inwall applying fire retardant or paste the modes such as flame retardant rubber, semicircle cover body can adopt metal material to make, and also can reach fire-retardant object, extinguishes when propagation of flame is arrived herein.
Further optimal way, shown in Fig. 1, Fig. 2, semicircle cover body 1 comprises and is positioned at middle large semicircle and is divided into large semicircle two ends and integrally formed with it two small semicircles, after these two semicircle cover bodies 1 fasten, form cavity in the middle of it, the interior wall energy of the small semicircle at two ends and the outer wall of cable closely connected.Wherein, middle large semicircle forms cavity, can be beneficial to the heat radiation of cable when usual, when there being fire spreading, its cavity is not owing to forming circulation with outside air, and the air in chamber can exhaust immediately, when making in fire spreading to cavity, extinguish due to anoxic, also accelerate to block the intensity of a fire.
The position fastened at two halves circular cover body 1 is also provided with fire-retardant sealing gasket.Wherein fire-retardant sealing gasket can adopt the edge paving that fire-retardant sealing strip, fire-retardant band, heat-resistant fireproof adhesive tape etc. fasten along two halves circular cover body 1, object is that the intensity of a fire making to spread contacts with fire proofing, also make in cavity and air exclusion simultaneously, also play the effect accelerating to block the intensity of a fire.
Cable shaft inner cable installs scene, and the utility model is installed on cable body, and the size of cover body and size and shape generally install additional according to the model of cable.
The utility model is applied between floor and floor, and the vertical shaft of existing floor partition, the cable trench that can also install additional in floor installs additional.After installing fire-retardant cover additional, one is prevent flame from spreading to high level, prevents cable fault from expanding; Two is the family's property losses reducing economy and city dweller; Three is improve repairing speed, recovers residential electricity consumption in time; Four is improve power supply quality and electricity sales amount.
Cable body installs additional fire-retardant cover, can install additional together when construction, along with laying of cable is installed on cable body, can also install additional in addition after laying.Dress can also be mended on existing high-rise building cable shaft inner cable.
Purposes: be applicable in controller switching equipment best in vertical run ignition of cable blocking effect, particularly skyscraper in cable shaft.
Function: the intensity of a fire effectively can be stoped after this cover body installed outward by cable to vertical spread and climbing, reduce the loss.
