Description

Technical Field

[0001] The invention relates to the technical field of smoke isolators, and in particular to a marine fire smoke isolator. Background Art

[0002] In a fire, combustible materials will produce a lot of harmful gases and smoke when they burn. The harmful gases will spread in the corridors of the ship along with the smoke and gradually fill the entire corridor. Therefore, when a fire occurs, people need to bend down when escaping to avoid inhaling smoke and causing physical injuries.

[0003] The existing Chinese patent with publication number CN118105646A discloses a fire smoke isolator, which belongs to the technical field of fire fighting equipment, and specifically includes a mounting tube, a mounting box is installed at the rear end of the mounting tube, and a compressed gas tank is fixed to the inside of the mounting box through a rear fixing seat and a front fixing seat; an electronic component is installed at the front end of the front fixing seat, an electromagnetic gas valve is installed at the air outlet end of the compressed gas tank, a fireproof airbag is installed at the front end of the electromagnetic gas valve, and a fire sensor is installed on the outside of the mounting tube. The invention is an independent installation design, which monitors the occurrence of fire through a fire sensor, and combines the design of electronic components, electromagnetic gas valves, compressed gas tanks and fireproof airbags. Once a fire occurs on a building floor, when the concentration of smoke spreads to the corridor and reaches a certain value, the device can quickly establish a smoke barrier wall in the corridor to prevent thick smoke from filling the entire corridor, and can provide a relatively safe escape environment for escapees, thereby minimizing casualties caused by the fire.

[0004] The above technical solution proposes an improvement on how to block smoke. In a fire, flames will ignite in the room of the ship and gradually spread in the corridor. Therefore, the smoke needs to be isolated outside the escape stairwell to facilitate the escape of personnel. At the same time, in order to prevent the escapees from inhaling smoke and poisoning in the corridor, the smoke cannot be completely blocked in the corridor. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a marine fire smoke isolator, which can effectively solve the problem of how to evacuate smoke in the prior art.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0012] Furthermore, the rolling roller comprises a roller body fixedly connected to the support bar and the bottom of the side wall of the barrier sac body, and the roller body helps to roll up the barrier curtain and provides gravity potential energy for the descent of the barrier curtain.

[0013] Furthermore, both ends of the stick body are fixedly connected to a fixed plate, one side of the fixed plate is fixedly connected to a movable plate via a spring, and the spring is in a compressed state, one side of the movable plate is fixedly connected to a contact capsule, and a blocking column is slidably inserted into the bottom of the stick body corresponding to the position of the contact capsule, the blocking column has an easy-to-break opening facing the contact capsule, and the blocking column is used to limit the contact capsule from sliding outward.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The present invention will be further described below in conjunction with the embodiments.

[0038] Example:

[0039] Reference Figures 1 to 11 A marine fire smoke isolator comprises a mounting frame 1 and a blocking curtain 2. The mounting frame 1 comprises a top frame 101 and a bottom support plate 102 hinged at the bottom of the top frame 101. A liquid-filled thermosensitive glass tube 103 is fixedly connected between the top frame 101 and the bottom support plate 102. A smoke exhaust component 3 is installed at the top and bottom of the top frame 101. A blocking curtain 2 is installed at the bottom of the smoke exhaust component 3. When the blocking curtain 2 is lowered, it forms a shield at the door to prevent smoke from spreading.

[0040] The smoke exhaust component 3 includes an air guide duct 301 which is fixedly installed at an angle on the top and bottom of the top frame 101. The air guide duct 301 is fixedly installed on the top of the blocking curtain 2. The end of the air guide duct 301 is fixedly connected to an exhaust pipe 303. An air suction groove 302 is opened on the air guide duct 301. The air guide duct 301 is fixedly connected to a guide frame 312 at a position corresponding to the air suction groove 302. The inclined air guide duct 301 will guide the smoke to move along the air guide duct 301, and the air suction groove 302 is distributed at the farthest point where the smoke moves along the air guide duct 301.

[0041] During installation, the top frame 101 is placed above the corridor safety door without hindering the opening of the safety door, and a hole needs to be opened on the wall to accommodate the exhaust pipe 303, so that the port of the exhaust pipe 303 extends to the outside of the room or the outside of the ship. Normally, the liquid-filled thermal glass tube 103 can connect the top frame 101 and the bottom support plate 102, so that the top frame 101 and the bottom support plate 102 form a frame for accommodating the rolled-up blocking curtain 2, and the blocking curtain 2 will be placed on the bottom support plate 102. When a fire occurs, the liquid-filled thermal glass tube 103 will burst at high temperature, and the connection between the liquid-filled thermal glass tube 103 and the top frame 101 and the bottom support plate 102 will be lost. The bottom support plate 102 will separate, and under the action of the bottom support plate 102 and the blocking curtain 2's own gravity, the blocking curtain 2 will fall rapidly and block outside the safety door to prevent smoke from entering the escape passage. When the smoke contacts the inclined blocking curtain 2, it will move along the inclined surface of the blocking curtain 2 and guide the smoke to the position of the air suction groove 302 and be discharged to the outside through the exhaust pipe 303. In this way, the smoke will be guided by the blocking curtain 2 during its spread above the corridor and be discharged to the outside of the corridor through the exhaust pipe 303. In this way, a large amount of smoke will not accumulate in the corridor, and it will be difficult for the smoke to fill the entire corridor, thereby improving the safety of people during escape.

[0042] Specifically, the blocking curtain 2 includes a blocking sac 202 and a support bar 201, the blocking sac 202 and the support bar 201 are distributed at intervals, and the bottom ends of the blocking sac 202 and the support bar 201 are commonly fixedly connected to a winding roller 4, the blocking sac 202 is a cavity structure, and the top of the blocking sac 202 is penetrated and fixedly connected with an air outlet pipe 304, and the port of the air outlet pipe 304 faces the air suction groove 302, and the air outlet pipe 304 is fixedly connected with a fixing frame 305, the bottom of the fixing frame 305 is fixedly connected with a spring, and the fixing frame 305 is fixedly connected with a blocking plate 306 through the spring, and the bottom end of the air outlet pipe 304 is fixedly connected with a breathable plate 307.

[0043] When the liquid-filled thermistor glass tube 103 ruptures, the winding roller 4 and the support bar 201 and the blocking capsule 202 will quickly stretch out, and the winding roller 4 falls to the ground, and the blocking capsule 202 needs to be filled with a volatile liquid, preferably liquid carbon dioxide, because liquid carbon dioxide can be stored at room temperature and fixed pressure, even in an ampoule, and at the same time, carbon dioxide cannot be ignited, and will not promote further expansion of the fire when it spreads to the corridor. The liquid carbon dioxide will be quickly heated when the blocking capsule 202 stretches out, and will evaporate into gas quickly compared to normal temperature conditions. This part of the gas will quickly increase in the blocking capsule 202, and the blocking capsule 202 will be filled with a large amount of liquid carbon dioxide. The air pressure increases rapidly, which produces a greater pressure on the blocking plate 306, causing the blocking plate 306 to overcome the spring force and move upward, so that the blocking plate 306 loses its blockage of the breathable plate 307, and the high-pressure carbon dioxide gas can be quickly released from the blocking bag 202 through the air outlet pipe 304, and form an airflow in the air guide duct 301. The pressure where the airflow flows will decrease, and the smoke will gradually approach the position with low pressure in the air intake groove 302, that is, the flowing carbon dioxide can suck the external smoke from the air intake groove 302 into the air guide duct 301, and discharge it outward through the exhaust pipe 303, thereby accelerating the speed at which the smoke is discharged from the exhaust pipe 303, further reducing the smoke content in the corridor, and further preventing the smoke from filling the corridor.

[0044] It should be noted that the outlet pipe 304 and its internal structure can be replaced by other pressure valve structures, and the pressure value provided by it is required to ensure that the carbon dioxide liquid is normally stored in the blocking bag 202 at room temperature, so that when a fire occurs, the liquid carbon dioxide can evaporate quickly.

[0045] Specifically, a plurality of inflatable sacs 203 are fixedly connected to one side of the blocking sac 202, the top and bottom of the inflatable sacs 203 are fixedly connected to an arc plate 204, the outer side of the arc plate 204 is fixedly connected to a sloped block 205, and the support bar 201 is provided with a slot corresponding to the position of the sloped block 205.

[0046] The extended support bar 201 and the blocking bag 202 hinder the diffusion of smoke and also block the path of the escapee. When the escapee passes through the support bar 201 and the blocking bag 202, the blocking bag 202 or the support bar 201 can be pushed away to stagger the blocking bag 202 and the support bar 201 to accommodate the escapee to escape from the corridor. When the support bar 201 and the blocking bag 202 are pushed away, the inclined block 205 will be compressed in the slot of the support bar 201 and squeeze the inflatable bag 203, and then the support bar 201 and the blocking bag 202 will be separated, and the escapee will be able to escape from the corridor. Afterwards, the blocking bag 202 remains stretched due to the high-pressure gas in it, and at the same time, the gravity of the winding roller 4 stretches the support bar 201 and the blocking bag 202, and the blocking bag 202 or the support bar 201 will quickly reset, and the overlapping support bar 201 and the blocking bag 202 will allow the arc plate 204 to contact the support bar 201, and allow the inclined block 205 to be reinserted into the support bar 201, so that the support bar 201 and the blocking bag 202 as a whole can regain the ability to block smoke, which not only allows the escapees to leave, but also quickly restores the ability to block smoke.

[0047] Specifically, the winding roller 4 includes a rod body 401 fixedly connected to the support bar 201 and the bottom of the side wall of the blocking capsule 202, the rod body 401 helps to roll up the blocking curtain 2 and provides gravitational potential energy for the descent of the blocking curtain 2, both ends of the rod body 401 are fixedly connected to fixed plates 402, one side of the fixed plate 402 is fixedly connected to a movable plate 404 through a spring, and the spring is in a compressed state, one side of the movable plate 404 is fixedly connected to a contact capsule 405, and a blocking column 403 is slidably inserted at the bottom of the rod body 401 corresponding to the position of the contact capsule 405, the blocking column 403 has an easy-to-break end facing the contact capsule 405, and the blocking column 403 is used to limit the contact capsule 405 from sliding outward.

[0048] In normal state, the breakable end of the blocking column 403 is located in the bottom plate of the stick body 401, and the blocking column 403 restricts the contact capsule 405 from sliding outward. Meanwhile, the breakable end cannot be broken because it is located in the bottom plate of the stick body 401, so that the blocking column 403 has a certain rigidity.

[0049] When the liquid-filled thermal glass tube 103 bursts, the winding roller 4 as a whole can provide the blocking curtain 2 with potential energy for falling, and when the support bar 201 and the blocking capsule 202 are rolled up, it is necessary to start rolling up from the position of the roller body 401, and let the blocking curtain 2 be placed on the bottom support plate 102 as a whole. After the liquid-filled thermal glass tube 103 bursts, the blocking curtain 2 falls rapidly under the support of the internal pressure of the blocking capsule 202 and the gravity of the winding roller 4 as a whole, and finally the roller body 401 falls to the ground. At the same time, the blocking column 403 contacts the ground and extends upward for a distance, so that the easy-to-break end of the blocking column 403 extends from the roller body 401, that is, the blocking column 403 is in contact with the capsule 401. 05, the blocking column 403 is in an easily breakable state. At this time, under the elastic force of the spring, the blocking column 403 breaks quickly, and the movable plate 404 extends out from the stick body 401, so that the contact capsule 405 contacts the walls on both sides of the corridor, and the stick body 401 is fixed as a whole between the walls on both sides. In this way, the bottom of the support bar 201 and the blocking capsule 202 will be fixed. When the escapee passes between the support bar 201 and the blocking capsule 202, the support bar 201 and the blocking capsule 202 will be able to return to their original positions due to the fixed bottom, and the support bar 201 and the blocking capsule 202 will not be unable to close again after the support bar 201 and the blocking capsule 202 are dispersed.

[0050] Specifically, a piston rack 406 is fixedly connected between the fixed plate 402 and the movable plate 404, and a piston rod 407 is slidably inserted in the piston rack 406. One end of the piston rod 407 passes through and is fixedly installed in the movable plate 404 and extends into the contact capsule 405. A separation membrane 409 is fixedly connected in the piston rack 406. A closed space is formed between the separation membrane 409 and the piston rack 406, and the closed space is filled with volatile liquid. A spike 410 is fixedly connected to the piston plate of the piston rod 407. When the spike 410 moves toward the separation membrane 409, it can puncture the separation membrane 409. The rod body of the piston rod 407 is a cavity structure, and a through hole 408 is opened at the end of the piston rod 407 close to the piston plate. After the separation membrane 409 is punctured, the volatile liquid enters the piston rod 407 through the through hole 408 and is introduced into the contact capsule 405 through the piston rod 407.

[0051] After the stick body 401 falls to the ground, the blocking column 403 breaks, and the moving plate 404 and the contact capsule 405 are quickly extended under the support of the spring and connected to the wall. At the same time, the extension of the moving plate 404 will cause the piston rod 407 to slide in the through hole 408. During the initial sliding, the piston rod 407 will not be hindered by other obstacles except friction. After the spike 410 pierces the separation membrane 409, the piston plate of the piston rod 407 enters the closed space between the through hole 408 and the separation membrane 409 and forms a piston structure. Under the action of the spring elastic force, the moving plate 404 04 and the contact capsule 405 gradually and slowly continue to extend outward, and the volatile liquid can also enter the rod body of the piston rod 407 through the through hole 408 and enter the contact capsule 405, or the gas after the volatile liquid evaporates enters the contact capsule 405 through the through hole 408 and the piston rod 407, causing the contact capsule 405 to expand. The expanded contact capsule 405 will increase the contact with the wall, so that the stick body 401 can be more firmly fixed between the walls on both sides, ensuring that the winding roller 4 as a whole can have a good fixing effect.

[0052] Specifically, the smoke exhaust component 3 also includes a water pipe 308 installed in the air guide duct 301, and a plurality of liquid outlet pipes 309 are fixedly connected to the water pipe 308. The liquid outlet pipes 309 are fixedly installed on the top of the blocking sac 202 and extend into the blocking sac 202. A one-way valve 310 is fixedly connected to the bottom of the liquid outlet pipe 309, and a nozzle 311 is fixedly connected to the bottom of the one-way valve 310.

[0053] After the carbon dioxide liquid has evaporated, water can be passed into the water pipe 308 and water mist can be sprayed into the blocking bag 202 through the nozzle 311 to reduce the temperature of the blocking bag 202, avoid scalding of the escapees when they come into contact with the blocking bag 202, and avoid deformation of the blocking bag 202 under high temperature conditions, thereby reducing the impact of high temperature on the blocking bag 202 during a fire. In addition, the water in the blocking bag 202 will also evaporate, which can ensure that a certain pressure is maintained in the blocking bag 202, so that after the escapees push the blocking bag 202 away, there is still a force to keep the blocking bag 202 straight, thereby helping the blocking bag 202 to reset.

[0054] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
