Abstract
The invention relates to a cable shaft fire-fighting device and method. A vertical fire-fighting pipe and a lower exhaust device are mounted in a shaft; a fire-fighting valve is provided with fire-fighting spray heads in a layered manner; an isolation smoke control baffle is arranged between cables; and a fire-fighting device controlled by a bimetallic strip is mounted at the lower part of a hoistway door. In the case of fire, physical isolation between the cables and air can be realized; the cable shaft fire-fighting device is widely applied to the fire prevention of a cable shaft, and the safety index of the cable shaft is increased; and moreover, the product realized by the technology can be produced in an industrial, standard, general and serial manner, and the technology belongs to the fields of building fire prevention and electric fire prevention.
Description
Technical field
The present invention relates to a kind of cable shaft fire plant and method thereof; The inner installation of vertical shaft erect extinguishing pipe and downward air exhaust device, and fire-protection valve and layering are provided with the fire extinguishing injector head, is provided with between the cable and isolates the Tobacco Control baffle plate; The extinguishing device of bimetal leaf control is installed in the hoistway door bottom; Fire occurs and can realize the physical isolation of cable and air, be widely used in the fire-fighting of cable shaft, improve the safety index of cable shaft; But product industrialization, standardization, generalization, producing in serial form that this technology realizes belong to Building Fire Protection and electric fire-fighting domain.
Background technology
Existing cable shaft present situation does not have fire prevention measure at all, artificial fire fighting that can only be passive in the back that catches fire, owing to can not in time put out a fire, the loss that causes is very big.
The invention provides a kind of cable shaft fire plant and fire-fighting method thereof, can realize automatic, timely, effectively fire extinguishing, improved the safety index of cable shaft.
Summary of the invention
A kind of cable shaft fire plant and method thereof are provided with fire-fighting spray device in cable shaft, the cable shaft outer wall is provided with the fire-fighting link device, and cable shaft is realized automatic fire prevention.
The present invention has following characteristic:
1. fire-fighting spray device is fire auto-induction type spray.
2. cable shaft outer wall fire-fighting link device is three grades of interlocks, will put out a fire with the automatic landing cable place of going into to catch fire of soil.
Description of drawings
Fig. 1, cable shaft fire plant overall structure sketch map
Fig. 2, cable shaft fire plant are met the firer and are made sketch map
1, cable shaft fire plant overall structure sketch map is as shown in Figure 1: cable shaft 1, and exterior wall 2, door 3, rotating shaft 4, fire extinguishing soil 5, from driver plate 6, main transmission plate 7, heat energy tablet 8, extinguishing pipe 9, valve 10, cable 11, clean-up port 12, treatment box 13.
2, the cable shaft fire plant is met the firer to make sketch map as shown in Figure 2: rotating shaft 41, and fire extinguishing soil 51, from driver plate 61, main transmission plate 71, heat energy tablet 81.
The specific embodiment
Fire-fighting spray device in the cable shaft: erect fire protection pipeline shown in Fig. 1 (9) in vertical shaft inside; Pipeline is the fireproof metal material; Inside is full of fire-fighting liquid, shown in Fig. 1 (10), locates to install fire sensor at valve, and the ignition of cable late gate is opened spray fire-fighting liquid automatically.
Cable shaft outer wall fire-fighting link device: behind the ignition of cable; Heat energy tablet such as Fig. 1 (8) are depicted as flexible fireproof flexible material, respond to the heat energy rear curved automatically upwards, this device utilization seesaw principle; The main transmission plate receives the thrust that (8) transmits and moves obliquely shown in Fig. 1 (7); (7) power transmission is simultaneously given from driver plate shown in Fig. 1 (6), and (6) bottom is stressed upwards lifts, and fire extinguishing soil falls into the cable place that catches fire along swash plate to lower slider automatically shown in Fig. 1 (5).
Claims (3)
1. cable shaft fire plant and method thereof, it is characterized in that: fire-fighting spray device is set in cable shaft, and the cable shaft outer wall is provided with the fire-fighting link device, and cable shaft is realized automatic fire prevention.
2. cable shaft fire plant according to claim 1 and method thereof is characterized in that: fire-fighting spray device is fire auto-induction type spray.
3. cable shaft fire plant according to claim 1 and method thereof is characterized in that: cable shaft outer wall fire-fighting link device is three grades of interlocks, will put out a fire with the automatic landing cable place of going into to catch fire of soil.
