Inorganic cloth fireproof roller shutter

Abstract

The utility model discloses an inorganic cloth fireproof roller shutter, which is characterized in that a drain pipe is arranged below a roller shutter structure, and a plurality of spray heads are uniformly arranged on the lower side of the drain pipe along the direction of a notch, so that a water spray system can be started at the first time when a fire disaster or toxic smog occurs; water mist sprayed by the spray heads quickly forms a continuous water curtain barrier in front of the roller shutter. The water curtain not only has a physical isolation effect, but also can effectively capture and cool high-temperature smoke and harmful particles, obviously reduce the concentration and diffusion speed of smoke, and prevent the smoke from spreading from a fire disaster area to other safe areas. Compared with a traditional dry type fireproof roller shutter, the structure improves the smoke prevention performance, and the flowing path of smoke in a building in the initial stage of a fire disaster can be controlled easily.

Description

Technical Field

[0001] This utility model belongs to the field of fireproof roller shutters, specifically, it relates to an inorganic fabric fireproof roller shutter. Background Technology

[0002] With the development of urban construction and the widespread use of high-rise buildings, fire prevention and control have received increasing attention. Inside buildings, especially in large public spaces, fire-resistant roller shutters are typically installed as important fire-resistant components to prevent the spread of fire and separate different fire compartments in the event of a fire. Traditional fire-resistant roller shutters are mostly made of inorganic fabric materials, possessing a certain degree of high-temperature resistance and flame retardancy, and can descend to form physical barriers in the event of a fire. However, they only have fire-resistant functions and cannot effectively block the spread of high-temperature smoke or toxic gases.

[0003] As is well known, the main cause of casualties in fires is not high-temperature burning, but the rapid spread of toxic fumes and the damage to the human respiratory system caused by high-temperature smoke. Traditional fireproof roller shutters usually cannot form a sealed space when they fall, and smoke can still escape from gaps, the bottom or side rails, causing non-fire areas to be quickly filled with smoke, seriously affecting the safety and effectiveness of personnel evacuation and rescue operations.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an inorganic fabric fireproof roller shutter, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An inorganic fireproof roller shutter includes: a connecting frame fixed to one side of a wall; two winding rollers are rotatably connected inside the connecting frame; a roller shutter structure is wound around the periphery of both winding rollers; a slot is provided at the bottom of the connecting frame for the roller shutter structure to pass through; a water inlet pipe is fixedly connected to one side of the connecting frame; a drainage component that cooperates with the water inlet pipe is provided on the inner wall of the connecting frame; a drainage pipe is provided at the outlet of the drainage component; and nozzles facing the slot are fixedly connected in a straight line at the bottom of the periphery of the drainage pipe.

[0008] Optionally, a mounting box is fixedly connected to one side of the connecting frame, and a servo motor is fixedly connected inside the mounting box. The output end of the servo motor passes through the connecting frame and is fixedly connected to one of the take-up rollers.

[0009] Optionally, the drainage assembly includes a solenoid valve located between the inlet pipe and the outlet pipe, with an outlet pipe connected below the solenoid valve and connecting to the two drain pipes.

[0010] Optionally, a synchronous pulley is fixedly connected to the end of each of the two take-up rollers away from the servo motor, and a synchronous belt is fitted between the two synchronous pulleys.

[0011] Optionally, guide rail assemblies are provided on both sides of the wall. The guide rail assembly includes two guide frames set on opposite sides, and the roller shutter is slidably connected within the space of the guide frames.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0013] This invention features a drain pipe installed below the roller shutter structure, with multiple nozzles evenly arranged along the groove direction on the lower side of the drain pipe. In the event of a fire or toxic smoke, the sprinkler system can be activated immediately, and the water mist sprayed from the nozzles quickly forms a continuous water curtain barrier in front of the roller shutter. This water curtain not only provides physical isolation but also effectively captures and cools high-temperature smoke and harmful particulate matter, significantly reducing the concentration and diffusion rate of smoke, and preventing smoke from spreading from the fire zone to other safe areas. Compared to traditional dry-type fireproof roller shutters, this structure improves smoke control performance and helps control the flow path of smoke inside the building during the initial stages of a fire.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Please see Figure 1-4 As shown, this embodiment provides an inorganic fabric fireproof roller shutter, including a connecting frame 1 fixed to one side of a wall. Two winding rollers 2 are rotatably connected inside the connecting frame 1, and a roller shutter structure 3 is wound around the periphery of each of the two winding rollers 2. A slot 4 is provided at the bottom of the connecting frame 1 for the roller shutter structure 3 to pass through. A water inlet pipe 5 is fixedly connected to one side of the connecting frame 1. A drainage assembly that cooperates with the water inlet pipe 5 is provided on the inner wall of the connecting frame 1. A drain pipe 6 is provided at the outlet of the drainage assembly. Sprinklers 7 are fixedly connected in a straight line at the bottom of the lower periphery of the drain pipe 6, facing the slot 4. The water inlet pipe can be connected to an external water pump.

[0025] By installing drainage pipes below the roller shutter structure and nozzles facing the slot, water mist can be sprayed in time when a fire or toxic smoke occurs, forming a water curtain barrier. This effectively slows down the spread of smoke to non-fire areas, thereby improving the smoke prevention capabilities inside the building and buying time for personnel evacuation and subsequent rescue.

[0026] In this embodiment, a mounting box is fixedly connected to one side of the connecting frame 1. A servo motor 11 is fixedly connected inside the mounting box. The output end of the servo motor 11 passes through the connecting frame 1 and is fixedly connected to one of the winding rollers 2. The servo motor enables automated winding of the roller shutter. By setting up a servo motor drive structure, automatic winding and unwinding control of the roller shutter is achieved. In emergencies, it can respond quickly and rapidly lower the fireproof roller shutter. When used in conjunction with a water curtain system, it improves the overall emergency response efficiency and intelligence level of the system, and reduces the risks caused by delays in human operation.

[0027] In this embodiment, the drainage assembly includes a solenoid valve 8 located between the inlet pipe 5 and the outlet pipe, with an outlet pipe 9 connected below the solenoid valve 8 and communicating with the two drain pipes. The drainage is achieved through the inlet pipe...

[0028] In this embodiment, each of the two take-up rollers 2 is fixedly connected to a synchronous pulley 12 at the end furthest from the servo motor 11, and a synchronous belt 13 is sleeved between the two synchronous pulleys 12. The synchronous pulleys and the synchronous belt work together to enable the two take-up rollers 2 to rotate simultaneously. The cooperation between the synchronous pulleys and the synchronous belt ensures that when the servo motor drives one take-up roller, the other roller moves in sync, ensuring that the roller shutter structure remains synchronous and flat during the winding and unwinding processes.

[0029] In this embodiment, guide rail assemblies are provided on both sides of the wall. Each guide rail assembly includes two guide frames 14 positioned opposite each other, and the roller shutter is slidably connected within the space of the guide frames 14. The roller shutter is rolled up by the guide frames 14. By using guide rail assemblies composed of guide frames, the movement path of the roller shutter structure can be effectively restricted, allowing it to fall smoothly in the vertical direction without shifting due to airflow or its own weight. This helps to form a stable and continuous barrier layer for the water curtain.
