In the figure: the fire-fighting device comprises a fire-fighting door frame 1, a fire-fighting rolling shutter door leaf 2, fire-fighting gas 3, a ventilation pipeline 4, a temperature-sensing detector 5, a standby power supply 6, a ventilation hole 7, a fire-fighting spring 8, a fire-fighting closing plate 9, a cable channel 10, a controller 11, a valve 12, an automatic fire-fighting gas storage cylinder 13, a gas outlet pipeline 14 and a fire-fighting heat-insulating material 15.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1 to 4, a wind-resistant and pressure-resistant super fire-proof rolling shutter, comprising: fire prevention door frame 1, fire prevention roll screen door leaf 2, vent pipe 4 and automatic fire extinguishing device, automatic fire extinguishing device sets up in the adjacent one side of fire prevention door frame, and automatic fire extinguishing device includes: the fire-fighting door frame comprises an automatic fire-fighting gas cylinder 13, a gas outlet pipeline 14, a temperature-sensing detector 5 and a controller 11, wherein the automatic fire-fighting gas cylinder 13 is communicated with a ventilation pipeline 4 arranged in a fire-fighting door frame 1 through the gas outlet pipeline 14, the automatic fire-fighting gas cylinder 13 is communicated with the temperature-sensing detector 5 through a cable channel 10, the controller 11 is communicated with the temperature-sensing detector 5 and the automatic fire-fighting gas cylinder 13 respectively, and a valve 12 is arranged on the automatic fire-fighting gas cylinder 13.
Further, a temperature detector 5 is positioned at the upper end of the fireproof door frame 1, and an alarm device is arranged on the temperature detector 5 and is an acousto-optic alarm. When the conflagration appears, along with the development of intensity of a fire, indoor temperature begins to rise gradually, and when the temperature rose to preset temperature 50 degrees centigrade, alarm device on the temperature-sensing detector 5 just began to send out the police dispatch newspaper, and when the temperature continued to rise to more than 60 degrees centigrade, controller 11 can begin to regulate and control automatic fire extinguishing device for the internal valve is opened, starts automatic fire extinguishing device.
Further, be equipped with vent pipe 4 in the fire prevention door frame 1, the inside left and right sides that is located vent pipe 4 of fire prevention door frame 1 all has air vent 7, and air vent 7 staggered arrangement, the end of ventilating of air vent 7 is connected with the side of fire prevention rolling screen door leaf 2, is equipped with mobilizable fire prevention closing plate 9 in the air vent 7, and fire prevention closing plate 9 is connected with the fire prevention spring 8 of fixing in vent pipe 4. When the automatic fire extinguishing device starts, make the internal valve open, at this moment the gaseous fire extinguishing agent in the automatic fire extinguishing gas storage cylinder 13 just lets in inside the breather pipe 4 through the pipeline 14 of giving vent to anger, when the gas in the breather pipe 4 reaches a certain amount, atmospheric pressure in the breather pipe 4 increases, and then promotes the removal of fire prevention closure plate 9 for the clearance increase between the fire prevention closure plate 9 air vent 7, and then release gaseous fire extinguishing agent. On the contrary, when the automatic fire extinguisher is in the closed state, the high pressure is not present in the vent pipe 4, and the fireproof closing plate 9 is contracted under the action of the elastic force of the fireproof spring 8, so that the vent hole 7 is in the closed state.
Further, the fireproof rolling door leaf 2 is composed of two combined fireproof rolling door panels, and the fireproof rolling door leaf 2 is filled with aluminum silicate cotton and a heat-insulating blanket fireproof and heat-insulating material 15. The fire-proof heat-insulating material 15 capable of being rolled up is filled between the two fire-proof rolling shutter door panels, when the fire is great, the multi-layer fire-proof panels block and the fire-proof heat-insulating material 15 acts, so that the time for resisting the fire can be prolonged for the fire-proof rolling shutter door 2.
Further, a heptafluoropropane fire extinguishing agent is stored in the automatic fire extinguishing gas storage cylinder 13. The heptafluoropropane gas extinguishing agent has high extinguishing efficiency, good cleanness, no residue after being completely vaporized in the atmosphere, basically no harm to human bodies and good electrical insulation.
In the scheme, the temperature-sensitive detector 5 and the automatic fire extinguishing device are additionally arranged on the fireproof door frame 1, so that the fireproof rolling door can give an alarm in advance when a fire disaster occurs, and can play a certain fire extinguishing role when the fire disaster moves through the gap of the fireproof door frame 1. When a fire disaster occurs, the automatic fire extinguishing device is started, the vent hole 7 is opened under the pushing of the pressure of the gas fire extinguishing agent, and the gas fire extinguishing agent is discharged outwards through the vent hole 7, so that the fire prevention and extinguishing effects are realized; when the fire-proof rolling door is in a normal state, the fire-proof closing plate 9 is closed, so that the interior of the ventilation pipeline 4 can be protected from being polluted by other impurities such as dust and the like. And fire-proof rolling shutter door leaf 2 comprises two fire door panels, can increase the fire-proof rolling shutter door and resist the barrier that blocks of intensity of a fire, further reinforcing fire behavior. Therefore, the fire-resistant wall can better resist fire through the functions of heat insulation, fire prevention and automatic fire extinguishing, more effectively block the spread of fire and enhance the time for coping with the fire.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and equivalent alternatives or modifications according to the technical solution of the present invention and the inventive concept thereof should be covered by the scope of the present invention.
