Description
Technical field
The utility model belongs to electric fire-control technical field, is specifically related to a kind of building inner cable vertical shaft fire plant.
Background technology
Cable shaft is that high-rise is for laying the vertical channel of service cable or communication cable, electric wiring for floor is extremely important, therefore, ensures Electrical Safety in cable shaft, the accident preventing electric fault from causing injures personnel's property safety, is current problem demanding prompt solution.But the fire protection of existing cable vertical shaft is perfect not, or passive manually suing and labouring after catching fire, or complex structure, causes cost to increase, and inefficiency, all can not deal with problems well.
Summary of the invention
For the problems referred to above, the utility model provides a kind of building inner cable vertical shaft fire plant, can carry out dual prevention, ensure the personnel's property safety in building, achieve significant social benefit, economic benefit after applying the condition of a fire in cable shaft.
For solving the problem, the utility model is achieved through the following technical solutions:
A kind of building inner cable vertical shaft fire plant, comprise the borehole wall, cable, at described Exterior cable also sheathed flame-retardant layer and shrinkage layer successively, temperature sensor, control system and spray system is also provided with in described shrinkage layer outside, the signal output part of described temperature sensor connects the signal input part of described control system, the signal output part of described control system connects the valve of spray system, to be controlled the opening and closing of spray system by control system.
For above-mentioned building inner cable vertical shaft fire plant, described flame-retardant layer is polyurethane foamed material.
For above-mentioned building inner cable vertical shaft fire plant, described shrinkage layer is polythene material.
For above-mentioned building inner cable vertical shaft fire plant, be horizontally disposed with multiple shutoff PLASTIC LAMINATED in cable shaft, multiple fire prevention zone will be divided in vertical shaft.
positive beneficial effect of the present utility model:
The utility model arranges polyurethane foam flame-retardant layer outside cable, once spark phenomenon appears in cable inside, then cable appearance produces high temperature, cause polyurethane foam undergoes rapid expansion, meanwhile, polyethylene shrink layer heat shrinkable, the inner expanded foam produced of compressing, blocks condition of a fire space further.
The utility model is set temperature sensor and spray system in vertical shaft, once Exterior cable stratiform is protected unsuccessfully, then temperature reaches appearance, after sensor acknowledge(ment) signal, spray can be opened immediately by control system, realization is put out by water and is lowered the temperature, and achieves significant social benefit, economic benefit after applying.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model fire plant;
In figure, 1 is the borehole wall, and 2 is cable, and 3 is flame-retardant layer, and 4 is shrinkage layer, and 5 is temperature sensor, and 6 is control system, and 7 is spray system, and 8 is shutoff PLASTIC LAMINATED.
Detailed description of the invention
Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described, but the utility model is not limited to these embodiments.
embodiment 1
A kind of building inner cable vertical shaft fire plant, comprise the borehole wall 1, cable 2, also sheathed polyurethane foam flame-retardant layer 3 and polyethylene shrink layer 4 successively in described cable 2 outside, temperature sensor 5, control system 6 and spray system 7 is also provided with in described polyethylene shrink layer 4 outside, the signal output part of described temperature sensor 5 connects the signal input part of described control system 6, the signal output part of described control system 6 connects the valve of spray system 7, to be controlled the opening and closing of spray system 7 by control system 6.Be horizontally disposed with multiple shutoff PLASTIC LAMINATED 8 in cable shaft, vertical shaft is divided into multiple subregion, to prevent spreading of the intensity of a fire.
The utility model is not limited to above-mentioned detailed description of the invention, and those skilled in the art also can make multiple change accordingly, but to be anyly equal to the utility model or similar change all should be encompassed in the scope of the utility model claim.
