Description
Technical Field
[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a mechanical smoke-proof curtain device. Background Art
[0002] Due to the airtight nature and high density of personnel in ship cabins, a fire can easily cause toxic smoke to quickly fill the entire cabin. This situation not only severely obstructs personnel's vision but also makes breathing difficult. If the fire is not effectively controlled, as the smoke concentration increases, personnel are very likely to suffocate or be poisoned by inhaling excessive toxic gases, ultimately resulting in the loss of the ship's overall combat effectiveness.
[0003] The main function of the existing ship smoke curtain device is to isolate the spread of smoke through the smoke barrier wall to prevent it from spreading to other areas of the cabin, thereby reducing the harm of smoke to personnel health.
[0004] However, these current smoke curtain devices generally suffer from poor smoke-blocking effectiveness, lack of smoke exhaust ports, and inability to achieve infinitely variable hovering. This results in their inability to effectively block smoke, exhaust smoke from a localized area, or hover at any desired location. To enhance the functionality and effectiveness of smoke curtain devices, improvements based on existing technologies are urgently needed. A smoke curtain device that can effectively isolate and exhaust smoke, while also enabling infinitely variable hovering, would enhance the safety and protection capabilities of ships, buildings, and other structures in the event of fire.

Under the cooperation of the pressure plate shaft and the waist hole, the pressure plate moves in the direction away from the left frame and the right frame. When the operating component is released, the pressure plate resets under the action of its own weight and presses the curtain.
[0010] As an optimization, a return spring is installed at the lower end of the pressure plate, one end of the return spring is connected to the lower end of the pressure plate, and the other end is fixedly connected to the lower door frame.

[0028] The present invention will be described in further detail below with reference to the accompanying drawings.
[0029] Specific implementation: see Figures 1-8 ,
[0030] A mechanical smoke-proof curtain device comprises a door frame 1, wherein the door frame 1 comprises a left frame body and a right frame body, and an upper frame body and a lower frame body; a rolling curtain assembly 2 is mounted on the upper frame body, and a curtain 3 is wound around the rolling curtain assembly 2, one end of the curtain 3 is fixedly connected to the reel of the rolling curtain assembly 2, and the other end is connected to a handle assembly 4 slidably mounted between the left frame body and the right frame body; a pressure plate 5 is movably mounted on the left frame body and the right frame body, and the curtain 3 extends along both sides of the width direction. Extending between the pressing plate 5 and the left and right frames, an operating assembly is provided on the handle. The operating assembly is connected to the pressing plate 5 through a linkage mechanism. By controlling the operating assembly, the pressing plate 5 can be driven away from or close to the left and right frames through the linkage mechanism. When the pressing plate 5 is away from the left and right frames, the curtain 3 can move up and down under the action of the rolling curtain assembly 2 or the handle assembly 4. When the pressing plate 5 is close to the left and right frames, the pressing plate 5 can press both sides of the curtain 3 against the left and right frames. In this way, by using the pressing plate 5 to press the curtain 3, a basic smoke isolation effect is achieved to ensure sealing. At the same time, the pressure of the pressing plate 5 on the curtain 3 can be easily adjusted through the operating assembly and the linkage mechanism, so that the position of the curtain 3 can be flexibly operated to achieve stepless adjustment, which is more flexible and convenient to use.
[0031] Specifically, a mounting groove 6 extending along the length direction is provided on the front or back of the left frame and the right frame, and a plurality of waist holes 7 are provided on at least one side wall of the mounting groove 6. The waist holes 7 are arranged obliquely, and the distance between the upper end and the bottom of the mounting groove 6 is greater than the distance between the lower end and the bottom of the mounting groove 6; the pressing plate 5 is movably installed in the mounting groove 6 by the pressing plate 5 axis passing through the waist hole 7; a sliding hole 8 extending along the length direction is provided on one side adjacent to the left frame and the right frame, the sliding hole 8 is communicated with the mounting groove 6 and is flush with the bottom of the mounting groove 6, and the two sides of the curtain 3 extend into the bottom of the mounting groove 6 of the left frame and the right frame respectively through the sliding holes 8, and can be pressed tightly to the bottom of the mounting groove 6 by the pressing plate 5;
[0032] When the handle is released, the first cable 9 is retracted, and the second cable 10 is pulled away from the handle and the handle is pulled back. When the handle is released, the first cable 9 is retracted, and the second cable 10 is pulled away from the handle and the handle is pulled back. When the handle is released, the first cable 9 is retracted, and the second cable 10 is pulled away from the handle and the handle is pulled back. When the handle is released, the first cable 9 is retracted, and the first cable 9 pulls the slider 11 to slide along the length direction of the handle toward the middle of the handle. At the same time, the slider 11 can compress the second cable 10 to bend in the direction close to the curtain 3, thereby lifting the pressure plate 5 and moving the pressure plate 5 upward. Under the cooperation of the pressure plate 5 axis and the waist hole 7, the pressure plate 5 moves in the direction away from the left frame and the right frame. When the operating component is released, the pressure plate 5 is reset under the action of its own weight, pressing the curtain 3.
[0033] In order to further improve the resetting effect of the pressure plate 5 and increase the pressing force on the curtain 3 after resetting, a resetting spring 13 is installed at the lower end of the pressure plate 5 in this embodiment. One end of the resetting spring 13 is connected to the lower end of the pressure plate 5, and the other end is fixedly connected to the lower door frame 1. In this way, under the dual action of the resetting spring 13 and the deadweight of the pressure plate 5, the pressing force of the pressure plate 5 on the curtain 3 is always maintained to ensure sealing.
[0034] The handle includes a handle tube 14, a handle 15 is provided in the middle of the handle tube 14, and a pressing assembly 16 is provided on the handle 15. The slider 11 is slidably fitted at both ends of the handle tube 14. One end of the first cable 9 is connected to the slider 11, and the other end extends along the handle tube 14, and passes through a guide wheel installed in the handle tube 14 and is connected to the pressing assembly 16 in the handle 15. By pressing the pressing assembly 16, the first cable 9 can be tightened, thereby driving the slider 11 to move along the handle tube 14. The specific structure of the pressing assembly 16 belongs to the existing technology. Generally, the first cable 9 is stretched by a torsion spring or other form of rotating mechanism, thereby pulling the slider 11 to move. It will not be described here.
[0035] Specifically, the slider 11 includes two relatively arranged slides, between which a clamping wheel 17 and an anchor head 18 are installed. The end of the first cable 9 is fixedly connected to the anchor head 18, and the side of the clamping wheel 17 close to the anchor head 18 is in contact with the second cable 10.
[0036] When in use, the pressing assembly 16 is pressed, and the pressing assembly 16 pulls the first cable 9, which drives the slider 11 to move along the handle tube 14. The pressure wheel 17 on the slider 11 will compress the second cable 10 to bend in the direction close to the curtain 3, so that its upper end pulls the upper end of the pressure plate 5 through the pulley 12, causing the pressure plate 5 to move upward. During the movement, due to the restriction of the inclined waist hole 7 and the axis of the pressure plate 5, the pressure plate 5 moves in the direction away from the door frame 1, thereby reducing the pressing force on the curtain 3. After the curtain 3 loses its restraint, it moves upward under the drive of the rolling curtain assembly 2. When it moves to a certain position, the pressing assembly 16 is released, and the pressure plate 5 falls back under the action of its own weight and the return spring 13, thereby tightening the second cable 10. The second cable 10 reacts on the pressure wheel 17 to force the slider 11 to reset. The reset of the slider 11 drives the pressing assembly 16 to reset through the first cable 9, thereby completing an infinite adjustment of the curtain 3.
[0037] In order to improve the functionality of the curtain 3 and enable it to effectively exhaust smoke when necessary, a smoke exhaust port is opened in the middle of the curtain 3, and a cover cloth 19 is provided on the smoke exhaust port. The lower end of the cover cloth 19 is fixedly connected to the curtain 3, the left and right ends are connected to the curtain 3 by zippers 20, and the upper end is connected to the curtain 3 by snap buttons 21. The structure is simple and easy to use.
[0038] In summary, the improved smoke-proof design of this application can more effectively isolate smoke and prevent its spread within a cabin or building. The integrated smoke exhaust port design can promptly exhaust smoke from a local area, maintaining clean air within the space. The implementation of an infinite hovering function allows the smoke curtain to stay in any position, flexibly responding to different fire scenarios. The simple structure makes operation more convenient and flexible.
