Description

Technical Field

[0001] This application relates to the field of fire protection, and more specifically, to a membrane structure fusion system for fire protection. Background Technology

[0002] When a fire occurs inside a building, firefighting is mainly carried out by sprinklers, which produces a large amount of dense smoke. However, for inflatable membrane structures, because the entire inflatable membrane is sealed, if a fire occurs, the dense smoke will be trapped inside the inflatable membrane and cannot be discharged in time.

[0003] To expel dense smoke, the membrane usually needs to be manually broken, but this method is too complicated and not conducive to quickly expelling dense smoke during a fire. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section above, some embodiments of this application provide a membrane structure fusing system for fire protection, wherein the membrane structure is at least installed in a building skylight or applied in a membrane structure building; the membrane structure fusing system includes: a clamping structure and a fusing structure; the clamping structure clamps one side of the membrane structure; the fusing structure is used to fuse the other sides of the membrane structure.

[0006] Furthermore, the membrane structure has multiple sides.

[0007] Furthermore, the fuse system also includes: a main fuse control module and multiple sub-fuse control modules; the main fuse control module is signal-connected to the multiple sub-fuse control modules, and the sub-fuse control modules are signal-connected to the multiple fuse structures.

[0008] Furthermore, the electrofusion control module includes a control switch with DPST function and a control switch electrically connected to the control switch with DPST function.

[0009] Furthermore, the fuse system also includes a power supply, and when the fuse structure blows, the power supply provides the fuse system with an instantaneous power of not less than 600 kW.

[0010] Furthermore, the fuse system also includes a smoke sensor, which is signal-connected to the electric fuse control module.

[0011] Furthermore, the membrane structure is an ETFE air cushion membrane.

[0012] Furthermore, the heating temperature of the fusible structure is greater than or equal to 500°C.

[0013] The beneficial effect of this application is that by fusing the membrane structure through the fusing structure, the membrane structure can be quickly destroyed, and the dense smoke can be discharged to the outside at the first time. Attached Figure Description

[0023] Reference Figure 1-4 , A membrane structure fusing system for fire protection is disclosed, wherein the membrane structure 3 is at least installed in a building skylight or applied to the membrane structure 3 building. The membrane structure fusing system includes: a clamping structure 1 and a fusing structure 2; the clamping structure 1 clamps one side of the membrane structure 3; the fusing structure 2 is used to fuse the other sides of the membrane structure 3. The membrane structure 3 can be installed in a building skylight, and the fusing structure 2 is also installed in the building skylight. In the event of a disaster, the fusing structure 2 fuses multiple sides of the membrane structure 3, leaving only the side of the membrane structure 3 clamped by the clamping structure 1. The fused portion then loses support and droops downwards, thereby opening the building skylight. This allows smoke generated during a disaster to escape from the building at the top, preventing the smoke from approaching the ground and hindering evacuation. Because the smoke exits from the top, the heat from the smoke heats the membrane structure 3 and causes it to contract inwards, causing the drooping membrane structure 3 to curl up on the clamping structure 1, further facilitating smoke exhaust and preventing the membrane structure from falling downwards, thus protecting the safety of people inside the building.

[0024] Specifically, the membrane structure 3 uses an ETFE air-cushion membrane. The membrane structure 3 has multiple sides. The clamping structure 1 is fixed to one of the multiple sides of the membrane structure 3, and the fusing structure 2 simultaneously fuses all five sides of the membrane structure 3. The membrane structure 3 having multiple sides means that it is a polygonal structure. Polygonal structures can have more adjacent sides when arranged, allowing the fusing structure 2 to more effectively fuse two sides of the membrane structure 3 simultaneously, saving costs and improving fusing synchronization.

[0025] Multiple membrane structures 3 are provided, arranged adjacent to each other and connected sequentially. These multiple membrane structures 3 form the roof of the building. Multiple fusing structures 2 are also provided, which fuse parts of the multiple membrane structures 3 to form a fusing region. The fusing region includes an annular region 4 and a circular region 5, with the circular region 5 located inside the annular region 4.

[0026] Specifically, the fusing system further includes: a central fusing control module and multiple sub-fusing control modules; the central fusing control module is signal-connected to the multiple sub-fusing control modules, and the sub-fusing control modules are signal-connected to the multiple fusing structures 2. The central fusing control module is a main control box, and the sub-fusing control modules are sub-control boxes. The main control box sends fusing signals to the sub-control boxes, and the sub-control boxes control the specific fusing structures 2 to fuse the membrane structure 3.

[0027] Specifically, the electrofusion control module includes a control switch with DPST function and a control switch electrically connected to the control switch with DPST function. Preferably, the control switch with DPST function is an SW-DPST switch.

[0028] Specifically, the fuse system also includes a power supply, and when the fuse structure 2 fuses, the power supply provides the fuse system with an instantaneous power of not less than 600kw.

[0029] Specifically, the fuse system also includes a smoke sensor, which is signal-connected to the electro-fuse control module.

[0030] Specifically, the heating temperature of the fusible structure 2 is greater than or equal to 500°C. The fusible structure 2 is a heating wire.

[0031] Both the clamping structure 1 and the fusion structure 2 are mounted on the polygonal frame 6. The clamping structure 1 includes a rotating roller 11, an arc-shaped needle 12, and a drive motor 13. The rotating roller 11 is rotatably connected to the polygonal frame 6 and abuts against the membrane structure 3. The arc-shaped needle 12 is fixed to the rotating roller 11. The arc-shaped needle 12 includes a connecting part 123, an abutting part 122, and a piercing part 121. The piercing part 121, the abutting part 122, and the connecting part 123 are fixed in sequence. The extension trajectories of the piercing part 121 and the abutting part 122 are arc-shaped, and the center of the arc-shaped trajectory coincides with the centerline of the rotating roller 11. The piercing part 121 and the abutting part 122 are spaced apart from the outer wall of the rotating roller 11, and the connecting part 123 fixes the abutting part 122 to the rotating roller 11 together. The rotating roller 11 presses against the membrane structure 3, and the membrane structure 3 partially covers the outer wall of the rotating roller 11. The drive motor 13 drives the rotating roller 11 to rotate. The rotation of the rotating roller 11 allows the piercing part 121 to penetrate into the membrane structure 3. Then, as the rotating roller 11 continues to rotate, the piercing part 121 protrudes outward from the inside of the membrane structure 3, so that the membrane structure 3 is located between the abutting part 122 and the rotating roller 11. The abutting part is used to fix the membrane structure 3 to the rotating roller 11. The drive motor 13 can also be replaced by a rocker arm or a handwheel.

[0032] Furthermore, a protrusion 111 is provided on the rotating roller 11, which is close to the abutment portion 122, thus creating a small gap between the protrusion 111 and the abutment portion 122, facilitating the pressing of the membrane structure 3. The puncture portion 121 is positioned away from the protrusion 111, thereby increasing the distance between the puncture portion 121 and the rotating roller 11, allowing the puncture portion 121 to penetrate the membrane structure 3 more effectively. (Refer to the attached drawings.) Figure 2 Polygonal frame 6 takes a quadrilateral as an example.
