Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, a guide rail 1 is a component of a fire-resistant shutter door, and mainly functions to guide a shutter slat 2.
Referring to fig. 2, a lot of smoke is generated frequently in case of fire, and the smoke is the most fatal in case of fire, and the fire area is easily exploded, so that wind pressure is generated at the curtain plate 2, and the smoke in the fire area overflows from the guide rail 1. Therefore, the embodiment provides a guide rail 1 of a fire-proof rolling door for preventing smoke from diffusing from the guide rail 1, which comprises the guide rail 1, a strip-shaped air bag 3 and an air pump 4.
The strip-shaped airbag 3 has the same length as the guide rail 1, and the strip-shaped airbag 3 is fixed to the inner wall of the guide rail 1 in the direction in which the guide rail 1 extends. A first air inlet pipe 31 is integrally formed on the strip-shaped air bag 3, one end of the first air inlet pipe 31 is communicated with the strip-shaped air bag 3, and the other end of the first air inlet pipe 31 is communicated with an air outlet of the air pump 4. The air pump 4 is electrically controlled, so the air pump 4 is placed near the motor of the fire shutter door and the circuit uses an emergency circuit as with the fire shutter door.
Because the fire-proof rolling door belongs to the fire-fighting equipment, frequent inspection and maintenance are required to ensure that the equipment can normally run. Therefore, in order to facilitate the removal, replacement, maintenance and repair of the strip airbag 3, the strip airbag 3 is further provided with a fastening edge 32.
The fastening edge 32 is a flat surface and can be integrally formed with the air bag, and the fastening edge 32 is tangent to the strip-shaped air bag 3 and the fastening edge 32 is equal to the strip-shaped air bag 3 in length; the fastening edge 32 is abutted against the inner wall of the guide rail 1, a plurality of through holes are formed in the fastening edge 32 along the length direction of the strip-shaped air bag 3, and through holes are also formed in the guide rail 1 at positions corresponding to the through holes in the fastening edge 32. Then, the bolt penetrates through the through hole, and the nut is screwed on the other end of the bolt, so that the strip-shaped air bag 3 is fixed on the inner wall of the guide rail 1. So make bar gasbag 3 can dismantle to bar gasbag 3 relatively fixed is more firm, and when the wind pressure appeared, bar gasbag 3 is difficult for taking place the dislocation, and then causes the cigarette leakage.
Because different curtain plates 2 are made of different materials, some curtain plates 2 are made of steel plates, and the curtain plates 2 have higher rigidity, so that the structure is simple and convenient; one side of the curtain board 2 is provided with the strip-shaped air bag 3 to compress the curtain board 2, and some curtain boards 2 are made of fireproof cotton, the rigidity of the curtain board 2 is poor, so that the strip-shaped air bags 3 are arranged on the two sides of the curtain board 2 and can be adapted to different curtain boards 2.
In order to enable the air bags at the two ends to be clamped synchronously, the two strip-shaped air bags 3 are communicated with each other, so that the number of the air pumps 4 can be reduced.
Most of the air pumps 4 have the characteristic of one-way circulation, but in order to prevent the spread of fire, after the air pumps 4 are damaged finally, the strip-shaped air bags 3 can still ensure the swelling state, so that the one-way valve is arranged in the first air inlet pipe 31, and air can only circulate from the air pumps 4 to the strip-shaped air bags 3.
The spreading of fire has uncertainty, and in order to make the strip-shaped air bag 3 resist the burning of open fire when the open fire spreads to the fire-proof rolling door, a layer of high-temperature-resistant fire-proof cloth 6 wraps the strip-shaped air bag 3. The material of the high-temperature-release fireproof cloth can be the same as that of the cloth-based fireproof rolling curtain.
Referring to fig. 3, the airbag 3 may be provided with a second inlet duct 33 so that the circuit is easily broken when a fire occurs and the airbag 3 may be inflated even when the power is cut off. Since it is necessary to inflate the strip-shaped airbags 3 after closing the fire-proof rolling door, and there is uncertainty in the direction of the fire, a second air inlet pipe 33 is provided in each of the two strip-shaped airbags 3.
The second air inlet pipe 33 passes through the guide rail 1, one end of the second air inlet pipe 33 is communicated with the air bag, the other end of the second air inlet pipe 33 is communicated with the atmosphere, and in order to enable the second air inlet pipe 33 to inflate the strip-shaped air bag 3 only, a second one-way valve 331 is arranged in the second air inlet pipe 33.
When the power is cut off in case of fire, the curtain plate 2 is firstly put down, then the strip-shaped air bags 3 are inflated through the movable air pump at one side without fire, or the strip-shaped air bags 3 are inflated through manpower, and a fire hydrant can be used if necessary, so that the strip-shaped air bags 3 clamp the curtain plate 2 by filling water into the strip-shaped air bags 3.
Similarly, in order to ensure that the pressure in the strip-shaped airbags 3 can be released after power failure, the fireproof roller shutters are opened, and the air outlet pipes 34 are arranged on the two strip-shaped airbags 3. The air outlet pipe 34 passes through the guide rail 1 through the second air inlet pipe 33, one end of the air outlet pipe 34 is communicated with the air bag, the other end of the air outlet pipe 34 is communicated with the atmosphere, and a pressure release valve 341 is arranged in the air outlet pipe 34. When the pressure in the strip-shaped air bag 3 needs to be released, the pressure valve is opened manually.
The implementation principle of the embodiment is as follows:
when the electric power system is not damaged in the case of fire, firstly, the curtain plate 2 is lowered through the motor; then the air pump 4 inflates the strip-shaped air bags 3, so that the two strip-shaped air bags 3 clamp the curtain board 2. When a fire disaster occurs and the electric power system is damaged, the fire is switched on to open the manual quick release device of the fireproof rolling door, and the curtain plate 2 is put down; then, the strip-shaped air bags 3 are inflated by the movable air pump, or the strip-shaped air bags 3 are inflated manually, and water can be filled into the strip-shaped air bags 3 by using a fire hydrant if necessary, so that the two strip-shaped air bags 3 clamp the curtain board 2. When the fire fighter needs to enter the fire scene to extinguish the fire, the pressure release valve 341 is opened to release the air in the strip-shaped air bag 3, and the curtain plate 2 is opened.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
