Description
Technical Field
[0001] The present invention relates to the technical field of fire fighting equipment, and in particular to a mechanical smoke curtain device. Background Art
[0002] Due to the airtightness and high density of people in ship cabins, once a fire occurs, it is very easy for toxic smoke to quickly fill the entire cabin in a short period of time. This situation will not only seriously hinder the personnel's vision, but also make 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, eventually leading to the loss of the overall combat effectiveness of the ship.
[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 smoke curtain devices currently have problems such as poor smoke prevention effect, lack of smoke exhaust ports, and inability to achieve infinite hovering. This results in them being unable to effectively block smoke, unable to exhaust smoke in local areas, and unable to hover at any position in actual use. In order to improve the functionality and use effect of smoke curtain devices, it is urgent to improve on the basis of existing technologies and develop a smoke curtain device that can effectively isolate smoke, effectively exhaust smoke, and can hover infinitely, thereby enhancing the safety protection capabilities of ships, buildings, etc. in the event of fire. Summary of the invention

DETAILED DESCRIPTION
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0018] For specific implementation: see Figure 1-Figure 8 , 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 which are arranged opposite to each other; a rolling curtain assembly 2 is installed on the upper frame body, and a curtain cloth 3 is wound around the rolling curtain assembly 2, one end of the curtain cloth 3 is fixedly connected to the winding shaft of the rolling curtain assembly 2, and the other end is connected to a handle assembly 4 which is slidably mounted between the left frame body and the right frame body; a pressing plate 5 is movably mounted on the left frame body and the right frame body, and the curtain cloth 3 is extended along the width direction of the two sides respectively. Extending between the pressing plate 5 and the left and right frames, an operating component is provided on the handle, and the operating component is connected to the pressing plate 5 through a linkage mechanism. By controlling the operating component, the pressing plate 5 can be driven to move 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 component 2 or the handle component 4. When the pressing plate 5 is close to the left and right frames, the pressing plate 5 can press the two sides of the curtain 3 against the left and right frames. In this way, the basic smoke isolation effect is achieved by using the pressing plate 5 to press the curtain 3 to ensure sealing. At the same time, the pressure of the pressing plate 5 on the curtain 3 can be conveniently adjusted through the operating component 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.
[0019] 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 inclined, 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 through 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, 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 against the bottom of the mounting groove 6 by the pressing plate 5; The linkage mechanism includes a first cable 9 arranged along the length direction of the handle, a second cable 10 opposite to the pressure plate 5 and arranged along the length direction of the pressure plate 5, and a slider 11 slidably connected to the handle. The middle part of the first cable 9 is connected to the operating component, and the other end is connected to the slider 11. One end of the second cable 10 is fixedly connected to the lower door frame 1, and the other end slides through the slider 11 and bypasses the pulley 12 installed on the upper frame and is connected to the upper end of the pressure plate 5. When the operating component is operated, the operating component can pull the first cable 9 to contract, so that the first cable 9 pulls the slider 11 to slide toward the middle part of the handle along the length direction 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 to press the curtain 3.
[0020] 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.
[0021] 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 mounted on 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 is connected to the pressing assembly 16 in the handle 15 after passing a guide wheel installed in the handle tube 14. 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 prior art. Generally, the first cable 9 is stretched by a torsion spring or other forms of rotating mechanisms, thereby driving the slider 11 to move, which will not be described in detail here.
[0022] 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.
[0023] When in use, the pressing assembly 16 is pressed, and the pressing assembly 16 pulls the first cable 9, and the first cable 9 drives the slider 11 to move along the handle tube 14. The clamping 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, so that the pressure plate 5 moves 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 clamping force on the curtain 3. After losing the restraint, the curtain 3 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 clamping 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 a stepless adjustment of the curtain 3.
[0024] In order to improve the functionality of the curtain 3 so that it can 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 through a zipper 20, and the upper end is connected to the curtain 3 through a snap 21, which has a simple structure and is easy to use.
[0025] In summary, the present application can more effectively isolate smoke and prevent its spread inside a cabin or building through an improved smoke-proof design. The integrated smoke exhaust port design can timely exhaust smoke in a local area and keep the air in the space clean. The infinite hovering function is realized, so that the smoke curtain can stay at any position, flexibly responding to different fire scenes, with a simple structure and more convenient and flexible operation.
