Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of smoke-proof hanging walls, and particularly relates to a smoke-proof curtain device applied to ship fire fighting. Background Art
[0002] Since the ship cabins are enclosed spaces with a dense population of people, once a fire breaks out, a large amount of toxic smoke is extremely likely to quickly spread in the cabins, causing the line of sight of people to be blocked and making it difficult to breathe. If the fire cannot be controlled, as the smoke concentration in the cabins continues to increase, it will soon cause people to suffocate or die from poisoning, and ultimately result in the loss of the combat effectiveness of the entire ship.
[0003] Currently, the smoke-proof curtain devices installed on ships do not have a smoke exhaust port design. Therefore, the functions and uses of the smoke-proof curtains are relatively single. Specifically, the smoke-proof hanging wall isolates the spread of smoke and prevents it from spreading to other areas indoors, thereby reducing the impact of smoke on human health. However, in actual use, it is impossible to exhaust the smoke in a local area. Therefore, the applicability and reliability of ordinary smoke-proof curtain devices are not high.
[0004] Therefore, improvements need to be made in this regard. Summary of the Utility Model
[0005] The technical problem solved by the utility model is to provide a smoke-proof curtain device applied to ship fire fighting to solve the problems raised in the above background art in view of the defects existing in the above-mentioned prior art.

[0024] As Figures 1-4As shown in the figure, a smoke-proof curtain device for ship fire protection is provided, which is characterized in that it includes: a retracting device for retracting and releasing the curtain; a curtain, one end of which is connected to the retracting device, and a smoke exhaust port for connecting to an external smoke exhaust pipe is opened on the curtain, and the curtain is driven to unfold or contract by the retracting device; a cover plate, which is arranged at the position of the smoke exhaust port, and the cover plate is connected to the curtain by a zipper and snap buttons. The cover plate closes the smoke exhaust port on the curtain, and an emergency cover plate is provided at the position corresponding to the smoke exhaust port on the cover plate; wherein, the emergency cover plate can be separated from the curtain by an external force, and the smoke exhaust pipe is inserted into the smoke exhaust port by taking out and stretching to exhaust smoke from a local area.
[0025] For this, a smoke-proof curtain device for ships is provided. Among the above, the retracting device is the same as the retracting devices on the market, and is used to drive the curtain to be curled. This is not an improvement, so it will not be elaborated here. The curtain is made of high-temperature resistant fabric, so the curtain is flexible and easy to be curled and retracted. By opening a smoke exhaust port on the curtain, the shape of the smoke exhaust port is set according to actual needs. A cover plate is set at the smoke exhaust port, and the cover plate is also made of high-temperature resistant fabric. The cover plate and the curtain are connected by high-temperature resistant zippers and snap buttons for closing the smoke exhaust port. The smoke exhaust port is a closed structure. When not in use, it is sealed by the cover plate and the emergency cover plate. When in use, the cover plate is opened, and an external smoke exhaust pipe is inserted to connect to an external fan for exhausting smoke. In an emergency, the emergency cover plate can be directly removed by an external force to expose the smoke exhaust port and insert the smoke exhaust pipe for exhausting smoke.
[0026] The specific usage process is as follows: When there is no need to exhaust smoke, use the smoke isolation function, and the retracting device lowers the curtain to achieve the purpose of smoke isolation. When there is a need to exhaust smoke, open the cover plate by unzipping the zipper and snap buttons, connect the smoke exhaust pipe to the smoke exhaust port, and connect the smoke exhaust pipe to the fan to drive the smoke in the area to be exhausted. After use, zip up the cover plate and the curtain with the zipper and snap buttons to form a seal.
[0027] Through the above structural design, the curtain is lowered by the retracting device to control the smoke in a local area and cut off the rapid diffusion and spread of the smoke. Further, the cover plate is opened from the curtain, and an external smoke exhaust pipe is used to connect to the smoke exhaust port and an external fan to effectively exhaust the smoke in the enclosed space of the ship's cabin, thereby minimizing the harm caused by the smoke to the greatest extent.
[0028] The curtain, the emergency cover plate, and the cover plate are all made of high-temperature resistant fabric, and the zipper and the sealing film are all made of high-temperature resistant materials. The overall structure is thinner, lighter, and softer, and is more smooth during the retracting and releasing process, without jamming or being unable to be curled, solving the problem of retracting and releasing the curtain made of traditional rigid materials.
[0029] A sealing film is provided along the inner direction of the exhaust port on the zipper. The cover sheet is connected to the curtain cloth through the zipper, and the sealing film presses on the zipper to form a seal.
[0030] To further improve the sealing performance at the exhaust port, a sealing film is arranged inside the zipper. When the zipper is zipped up, the sealing film fills the gaps existing in the zipper teeth, ensuring the sealing of the whole structure.
[0031] Specifically, the lower part of the cover sheet is stitched to the curtain cloth with heat-resistant sewing threads. The two sides of the cover sheet are connected to the curtain cloth through the zipper, and the upper part of the cover sheet is connected to the edge sealing tab through snap buttons.
[0032] An edge sealing tab is arranged at the upper part of the curtain cloth at the exhaust port, and the upper part of the cover sheet is connected to the edge sealing tab by snap buttons.
[0033] The sealing film is a heat-resistant sealing film.
[0034] One or more reflective strips are provided on the curtain cloth.
[0035] The emergency cover sheet is sealed with glue between it and the cover sheet, and an emergency pull ring for opening is provided below the emergency cover sheet.
[0036] In an emergency state, the emergency pull ring can be directly pulled down by an external force to remove the emergency cover sheet, exposing the exhaust port to insert the exhaust pipe for smoke exhaust. The emergency pull ring is also made of heat-resistant fabric.
[0037] The above does not impose any limitation on the technical scope of the present utility model. Any modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
