Description

Technical Field

[0001] The utility model relates to the technical field of shipbuilding, in particular to a ship fire smoke barrier device. Background Art

[0002] Ship fires are a major threat to shipping safety. When a fire breaks out, high temperatures, thick smoke, and flames spread rapidly. Due to the complex spatial structure of a ship's cabins, smoke can easily spread rapidly up stairs to all floors, posing a serious threat to the lives of crew members and the ship's property. To effectively prevent the spread of smoke and ensure ship safety, smoke doors are typically installed between floors.

[0003] However, traditional smoke-proof doors are usually kept closed, which brings inconvenience to the crew's daily passage and cargo transportation, and frequent opening and closing can easily cause damage to the door body.

[0004] However, some smoke-proof doors in the prior art that rely on electricity to maintain an open state cannot close automatically once a fire causes a power outage, thereby losing their smoke-barrier function and posing a safety hazard.

[0005] Therefore, it is necessary to improve the existing ship fire smoke barrier technology to overcome the defects of the existing technology. Utility Model Content

[0006] In order to overcome the problems existing in the relevant technology, the purpose of the present invention is to provide a ship fire smoke barrier device, which realizes a normally open function through an electromagnetic releaser and a fixing bracket, and realizes an automatic closing function through a fire alarm system, an electronic control component and an electromagnetic release, so as to overcome the problems of inconvenience in use and the inability to achieve a barrier effect when the power is off in the prior art.

[0007] A marine fire smoke barrier device, comprising:

[0008] A smoke-tight door, wherein the smoke-tight door is provided with a door closer, and comprises a door frame, a door leaf and a hinge, wherein the door leaf is rotatably connected to the door frame via the hinge;

[0009] An electromagnetic release, the electromagnetic release comprising a fixed portion and a movable portion, the movable portion being fixed to the surface of the door leaf and disposed away from the hinge, and the fixed portion being magnetically fixed to the movable portion when the smoke-tight door is in an open state;

[0010] A fixing frame, the fixing frame being fixed to both sides of the door frame, and the fixing portion being fixed to the fixing frame;

[0011] A fire alarm system, the fire alarm system being used to detect fires and issue fire signals;

[0012] An electronic control component for receiving the fire signal and controlling the electromagnetic releaser, the electronic control component including a power supply, a central controller and a manual controller, the power supply, central controller, manual controller and electromagnetic releaser being electrically connected in sequence, and the fire alarm system being electrically connected to the central controller.

[0013] An electromagnetic release maintains the smoke-tight door open, facilitating the passage of personnel and cargo. A mounting bracket provides a stable mounting base for the electromagnetic release, ensuring reliable operation even in the ship's rocking conditions. Furthermore, securing the door with the bracket effectively ensures daylighting and increases space within the cabin. The fire alarm system promptly detects a fire and issues a signal. Upon receiving the signal, the electronic control unit releases the electromagnetic release, and the smoke-tight door automatically closes via the door closer. This improves the smoke barrier's response speed, effectively preventing the spread of smoke and preventing it from moving between decks, thus safeguarding the lives and property of crew members.

[0014] In some embodiments, the door leaf includes a first door body and a second door body arranged opposite to each other, and a cover plate is provided on the first door body, and the cover plate is arranged along the edge of the first door body, and the cover plate is used to cover the gap between the first door body and the second door body. The first door body and the second door body each correspond to one electromagnetic releaser, and two fixing brackets are provided, and the two fixing brackets are respectively arranged on both sides of the door frame.

[0015] The double-door structure forms a buffer space when closed, and the cover plate covers the gap between the first door body and the second door body, further reducing the possibility of smoke leakage from the gap and improving the sealing of the smoke-tight door.

[0016] In some embodiments, the central controller includes a time delay relay, the power supply, the time delay relay, the manual controller and the electromagnetic releaser are electrically connected in sequence, and the time delay relay is used to control the two electromagnetic releasers to release in a predetermined time sequence.

[0017] By releasing the electromagnetic releaser in a predetermined time sequence through the time delay relay, the closing order of the first door body and the second door body can be effectively guaranteed, and the collision when the two door bodies are closed at the same time due to the presence of the cover plate can be avoided, thereby ensuring the normal closing of the smoke-tight door.

[0018] In some embodiments, the central controller is located in the ship's control room, and the manual controller is located around the smoke-tight door.

[0019] The central controller is located in the ship's control room, allowing crew members to centrally monitor the status of the smoke-tight doors, promptly detect and address abnormal situations, and improve ship management efficiency. The manual controller is located near the smoke-tight doors, allowing on-site personnel to quickly manually operate the doors in an emergency, improving the flexibility and timeliness of emergency response.

[0020] In some embodiments, the electromagnetic releaser of the second door body is further connected to a delayed power supply, which includes a delayed power supply, which is electrically connected to the fixed part, and is used to power the fixed part when the power supply is disconnected.

[0021] The delayed power supply can provide the electromagnetic release with backup power for a period of time when the main power is disconnected, ensuring that the second door can be closed later than the first door, ensuring the closing order of the first and second doors, and avoiding interference between the first and second doors when closing.

[0022] In some embodiments, both the first door body and the second door body are further provided with an observation window, and the observation window is provided with tempered glass.

[0023] By using observation windows with tempered glass, crew members can intuitively understand the situation in the fire area without opening the smoke-tight door, judge the size of the fire, smoke concentration and other information, which is conducive to taking timely response measures and improving the efficiency and safety of fire handling.

[0024] In some embodiments, an escape path guidance component is further provided in the first door body and the second door body, and the escape path guidance component includes a transparent display, a display driver and a battery electrically connected in sequence, the tempered glass is provided with two layers, the transparent display is provided between the two layers of tempered glass, the display driver is communicatively connected to the fire alarm system, the transparent displays on the first door body and the second door body are in opposite directions, the transparent displays are used to display escape information, and the display driver is used for fire signals and drives the transparent display.

[0025] The escape route guidance component provides clear escape route instructions in the event of a fire, especially in smoke-filled, low-visibility conditions. It effectively guides personnel to escape quickly and safely, minimizing casualties. The displays on the first and second doors face opposite directions, ensuring that personnel can see the escape information regardless of the direction they approach the smoke-tight door.

[0026] In some embodiments, the door leaf and the door frame both include a surface frame and a heat-resistant filler. The surface frame is made of a fireproof material. A cavity is formed in the surface frame, and the cavity is filled with the heat-resistant filler.

[0027] The structure of the surface frame and heat-resistant filler can effectively block the transfer of heat, slowing down the spread of fire to a certain extent, and buying more precious time for personnel escape and fire fighting.

[0028] In some embodiments, a guard is provided at the edge of the surface frame, the guard is made of aluminum material, and the heat-resistant filler is an aluminum honeycomb core.

[0029] Edge guards protect the edges of smoke-tight doors, preventing them from being knocked or deformed, and extending their service life. Aluminum edge guards and aluminum honeycomb cores enhance the strength and durability of smoke-tight doors while reducing their weight, making them easier to operate and install, and improving the fuel economy of the vessel.

[0030] In some embodiments, when the fixed portion and the movable portion are fixed by magnetic attraction, the opening angle of the smoke-tight door is 180 degrees.

[0031] The 180-degree opening angle can keep the passage unobstructed to the greatest extent. For areas where large equipment needs to pass frequently or where the passage needs to be kept unobstructed, it can facilitate the passage of personnel and large equipment and improve the practicality of the smoke-tight door.

[0032] The beneficial effects of the utility model are:

[0033] The utility model provides a ship fire smoke barrier device, which includes a smoke-tight door, an electromagnetic releaser, a fixing bracket, a fire alarm system and an electronic control component. The smoke-tight door is kept open by the electromagnetic releaser to facilitate the passage of personnel and cargo. The fixing bracket provides a stable installation base for the fixing part of the electromagnetic releaser, ensuring that it can work reliably even in a shaking ship environment. At the same time, fixing by the fixing bracket can effectively ensure the lighting in the cabin and increase the space in the cabin. The fire alarm system detects the fire in time and sends a signal. After receiving the signal, the electronic control component releases the electromagnetic release. After the release, the smoke-tight door is automatically closed by the door closer, which improves the response speed of the smoke barrier, effectively blocks the spread of smoke, and protects the life and property of the crew.

[0046] The following describes preferred embodiments of the present invention in more detail with reference to the accompanying drawings. Although preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0047] Example 1

[0048] like Figures 1-4 As shown, this embodiment provides a marine fire smoke barrier device, which includes:

[0049] A smoke-tight door 100 is provided with a door closer 200. The smoke-tight door 100 includes a door frame 110, a door leaf 120, and a hinge 130. The door leaf 120 is rotatably connected to the door frame 110 via the hinge 130.

[0050] The electromagnetic release 300 includes a fixed portion 320 and a movable portion 310. The movable portion 310 is fixed to the surface of the door leaf 120 and is disposed away from the hinge 130. When the smoke-tight door 100 is in the open state, the fixed portion 320 is magnetically fixed to the movable portion 310.

[0051] A fixing frame 400 , wherein the fixing frame 400 is fixed to both sides of the door frame 110 , and the fixing portion 320 is fixed to the fixing frame 400 ;

[0052] A fire alarm system 500, which is used to detect fires and send fire signals;

[0053] The electronic control component 600 is used to receive the fire signal and control the electromagnetic releaser 300. The electronic control component 600 includes a power supply 610, a central controller 620 and a manual controller 630. The power supply 610, the central controller 620, the manual controller 630 and the electromagnetic releaser 300 are electrically connected in sequence, and the fire alarm system 500 is electrically connected to the central controller 620.

[0054] The door leaf 120 can be a single-leaf structure or a double-leaf structure. Each door leaf 120 can ensure the stability of opening and closing of the smoke-tight door 100 through one or more electromagnetic releasers 300.

[0055] Smoke-tight doors, also known as smoke-proof doors, are doors that can prevent smoke from spreading for a certain period of time.

[0056] Specifically, such as Figure 2 、 Figure 3 As shown, the door leaf 120 includes a first door body 121 and a second door body 122 arranged opposite to each other, and a cover plate 1211 is provided on the first door body 121, and the cover plate 1211 is arranged along the edge of the first door body 121, and the cover plate 1211 is used to cover the gap between the first door body 121 and the second door body 122, and the first door body 121 and the second door body 122 each correspond to one electromagnetic releaser 300, and there are two fixing frames 400, and the two fixing frames 400 are respectively arranged on both sides of the door frame 110.

[0057] More specifically, a fireproof seal is provided between the door frame 110 and the door leaf 120. The fireproof seal is embedded in the door frame 110. The fireproof seal may be an intumescent fireproof sealing strip, etc. The installation method of the fixing frame 400 may be adjusted according to actual conditions, such as welding fixation, embedded installation, etc.

[0058] Since the cover plate 1211 is provided on the first door body 121, it is necessary to control the closing sequence of the first door body 121 and the second door body 122. Otherwise, the presence of the cover plate 1211 will interfere with the closing of the door leaf 120. The closing sequence of the first door body 121 and the second door body 122 can be controlled by timing control using a control chip, a delay circuit, or a sequencer. Alternatively, a wireless communication module such as Bluetooth or ZigBee can be used to control the operation of the two electromagnetic releasers 300 separately, and delay control can be achieved through software programming.

[0059] Further, such as Figure 4As shown, the central controller 620 includes a time delay relay 621, the power supply 610, the time delay relay 621, the manual controller 630 and the electromagnetic releaser 300 are electrically connected in sequence, and the time delay relay 621 is used to control the two electromagnetic releasers 300 to release in a predetermined time sequence.

[0060] Specifically, the central controller 620 is arranged in the ship's centralized control room, and the manual controller 630 is arranged around the smoke-tight door 100 .

[0061] More specifically, the central controller 620 is set on the fire alarm panel, and the manual controller 630 is set on the manual control panel. The manual controller 630 is a manual switch. The positive and negative poles of the electromagnetic releaser 300 are respectively connected to the positive and negative poles of the delay relay 621. The control is performed by connecting the manual controller 630 on the positive line of the two electromagnetic releasers 300 and the delay relay 621.

[0062] The cut-off time of the delay relay 621 can be set arbitrarily within two minutes. In this embodiment, the electromagnetic releaser 300 on one of the doors performs the release action after a delay of two seconds after receiving the release instruction.

[0063] Furthermore, both the first door body 121 and the second door body 122 are provided with an observation window 125 , and the observation window 125 is provided with tempered glass 1251 .

[0064] The number of layers of the tempered glass 1251 can be arbitrary, and can be a single layer or multiple layers. In this embodiment, the tempered glass 1251 has two layers.

[0065] Furthermore, an escape path guidance component is provided in the first door body 121 and the second door body 122. The escape path guidance component includes a transparent display, a display driver and a battery that are electrically connected in sequence. The tempered glass 1251 is provided with two layers, and the transparent display is arranged between the two layers of tempered glass 1251. The display driver is communicatively connected to the fire alarm system 500. The transparent displays on the first door body 121 and the second door body 122 are in opposite directions. The transparent displays are used to display escape information, and the display driver is used for fire signals and drives the transparent displays.

[0066] Specifically, in addition to transparent displays, other display methods can also be used, such as LED light strips. LED light strips are more cost-effective, but the amount of information displayed is limited. Escape information can include the location of the fire, the direction of the emergency exit, and the distance to the emergency exit. It can also be linked with the ship's fire alarm system 500 and monitoring system to dynamically adjust the escape route based on the fire situation.

[0067] More specifically, the door leaf 120 and the door frame 110 both include a surface frame 123 and a heat-resistant filler 124 . The surface frame 123 is made of a fireproof material. A cavity is formed in the surface frame 123 , and the cavity is filled with the heat-resistant filler 124 .

[0068] Furthermore, a guard is provided at the edge of the surface frame 123 , and the guard is made of aluminum material. The heat-resistant filler 124 is an aluminum honeycomb core.

[0069] The surface frame 123 can be made of various materials, such as aluminum, lightweight composite materials, tempered fiberglass, high-temperature resistant resin, ceramic materials, etc. The heat-insulating filler 124 can be made of various materials, such as graphene, to enhance the heat insulation performance of the smoke-tight door 100 .

[0070] When the fixed portion 320 is magnetically fixed to the movable portion 310 , the opening angle of the smoke-tight door 100 is 180 degrees.

[0071] Working process in this embodiment:

[0072] 1. Daily status:

[0073] The smoke-tight door 100 is in an open state, and the fixed portion 320 and the movable portion 310 are fixed to each other by magnetic attraction.

[0074] Crew and cargo can pass freely without manually opening and closing the smoke-tight door 100.

[0075] The central controller 620 monitors the status of the fire alarm system 500 and the manual controller 630 in real time, and controls the power supply 610 to supply power to the electromagnetic releaser 300 to keep the smoke-tight door 100 open.

[0076] 2. When a fire occurs:

[0077] The fire alarm system 500 detects a fire and sends a fire signal to the central controller 620 .

[0078] After receiving the fire signal, the central controller 620 immediately cuts off the power supply 610 of the time delay relay 621 , and the time delay relay 621 is disconnected from the electromagnetic releaser 300 .

[0079] One of the electromagnetic releasers 300 is immediately powered off, releasing the corresponding door body.

[0080] After a delay of two seconds, the time delay relay 621 is completely disconnected, and the other electromagnetic releaser 300 is powered off, releasing the corresponding door body.

[0081] The two door bodies are automatically closed under the action of the door closer 200, and rely on the fireproof seal to form a closed fire barrier to prevent the spread of smoke.

[0082] At the same time, the escape path guidance component is activated, and the transparent display shows the direction and distance of the safe exit to guide people to escape.

[0083] 3. Manual operation:

[0084] The crew can manually cut off the power supply 610 of the electromagnetic releaser 300 and close the smoke-tight door 100 through the manual controller 630 located near the smoke-tight door 100.

[0085] The manual controller 630 is connected to the time delay relay 621. Operating the manual controller 630 can control the time delay relay 621 to be disconnected, thereby controlling the two electromagnetic releasers 300 to release the door bodies in sequence.

[0086] This embodiment of the marine fire and smoke barrier device effectively addresses the safety hazards and inconveniences associated with conventional smoke-tight doors 100 by installing a cover plate 1211 and fireproof seals on the double-door structure and using a time-delay relay 621 to control the release sequence of the two electromagnetic releasers 300. The device normally maintains the smoke-tight doors 100 open, facilitating crew passage and cargo transport. In the event of a fire, the two doors automatically close in a predetermined sequence, forming a sealed fire barrier that prevents the spread of smoke and improves vessel safety. Furthermore, the design of the observation window 125 and escape path guidance assembly further enhances emergency response capabilities in the event of a fire, maximizing the safety of personnel and vessel property.

[0087] Example 2

[0088] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 As shown, this embodiment provides a marine fire smoke barrier device, which includes:

[0089] A smoke-tight door 100 is provided with a door closer 200. The smoke-tight door 100 includes a door frame 110, a door leaf 120, and a hinge 130. The door leaf 120 is rotatably connected to the door frame 110 via the hinge 130.

[0090] The electromagnetic release 300 includes a fixed portion 320 and a movable portion 310. The movable portion 310 is fixed to the surface of the door leaf 120 and is disposed away from the hinge 130. When the smoke-tight door 100 is in the open state, the fixed portion 320 is magnetically fixed to the movable portion 310.

[0091] A fixing frame 400 , wherein the fixing frame 400 is fixed to both sides of the door frame 110 , and the fixing portion 320 is fixed to the fixing frame 400 ;

[0092] A fire alarm system 500, which is used to detect fires and send fire signals;

[0093] The electronic control component 600 is used to receive the fire signal and control the electromagnetic releaser 300. The electronic control component 600 includes a power supply 610, a central controller 620 and a manual controller 630. The power supply 610, the central controller 620, the manual controller 630 and the electromagnetic releaser 300 are electrically connected in sequence, and the fire alarm system 500 is electrically connected to the central controller 620.

[0094] In this embodiment, the door leaf 120 is made of steel plate.

[0095] Furthermore, the electromagnetic release 300 can be integrated with a temperature sensor. When the temperature reaches a preset value, it automatically releases the smoke-tight door 100, enhancing the safety of the device. The electromagnetic release 300 can also be integrated with a self-checking function to regularly check its own status and issue a fault alarm signal to facilitate repair and maintenance.

[0096] The mounting bracket 400 can be made of various materials, such as high-temperature-resistant and corrosion-resistant alloys, to improve its durability. The mounting bracket 400 can also be secured using various methods, such as bolting or welding, to accommodate different installation environments. The mounting bracket 400 can also be designed with adjustable height to accommodate installation requirements on various vessels.

[0097] Specifically, the door leaf 120 includes a first door body 121 and a second door body 122 that are relatively arranged. The first door body 121 is provided with a cover plate 1211, and the cover plate 1211 is arranged along the edge of the first door body 121. The cover plate 1211 is used to cover the gap between the first door body 121 and the second door body 122. The first door body 121 and the second door body 122 each correspond to one electromagnetic releaser 300, and there are two fixing frames 400, which are respectively arranged on both sides of the door frame 110.

[0098] Furthermore, the electromagnetic releaser 300 of the second door body 122 is also connected to a delayed power supply 330, which includes a delayed power supply 610. The delayed power supply 610 is electrically connected to the fixed part 320, and the delayed power supply 610 is used to power the fixed part 320 when the power supply 610 is disconnected.

[0099] like Figure 5As shown, in this embodiment, the closing sequence control of the first door body 121 and the second door body 122 is achieved by a delayed power supply 330. Compared with the implementation method in Example 1, this method can maintain the release sequence of the two electromagnetic releasers 300 even when all power supplies 610 on the ship fail.

[0100] At the same time, because a delayed power supply is provided for time delay control, the two electromagnetic releasers 300 can be switched on and off via a single power supply line. In other words, the central controller 620 is connected to a manual controller 630 via a single line, and the manual controller 630 then branches out into two lines connected to the two electromagnetic releasers 300. This allows the two electromagnetic releasers 300 to be released sequentially through a single manual controller 630, effectively improving the efficiency of manual control.

[0101] Specifically, the manual controller 630 can adopt different operation modes, such as touch control, button control, voice control, etc.

[0102] More specifically, the delay time can be controlled by setting the capacity of the delay power supply 610. The delay power supply 610 maintains a predetermined capacity when the circuit is working normally, and provides the electromagnetic releaser 300 with a working voltage for a predetermined delay time when the peripheral power supply circuit is disconnected.

[0103] More specifically, the time-delay power supply 610 can be any object capable of providing short-term power, such as a battery or capacitor. The predetermined capacity of the time-delay power supply 610 can be determined through post-installation testing or by calculating the power consumption of the electromagnetic release 300. The time-delay power supply 610 can also be designed to be replaceable for easy maintenance and replacement.

[0104] The working process in this embodiment:

[0105] 1. Daily status:

[0106] The smoke-tight door 100 is in an open state, which is convenient for passage.

[0107] The delayed power supply 330 is in a charging state and stores electrical energy.

[0108] 2. When a fire occurs:

[0109] The fire alarm system 500 detects a fire and sends a fire signal to the central controller 620 .

[0110] After receiving the fire signal, the central controller 620 immediately cuts off the main power supply 610 and the electromagnetic releaser 300 is powered off.

[0111] After the electromagnetic releaser 300 of the first door body 121 loses power, the door body is released immediately.

[0112] The electromagnetic releaser 300 of the second door body 122 continues to be powered by the delayed power supply 330 and releases the door body after a delay period.

[0113] 3. Power outage:

[0114] If a fire occurs and the vessel loses power, the main power supply 610 will be disconnected.

[0115] Since the delayed power supply 330 of the second door 122 stores electrical energy, it can continue to power the electromagnetic release 300 for a period of time, ensuring the delayed closing of the second door 122. Even in the event of a power outage, the two doors can still be closed sequentially, thereby improving the reliability of the device.

[0116] 4. Manual operation:

[0117] The crew can cut off the power supply 610 of the electromagnetic releaser 300 through the manual controller 630 and manually close the smoke-tight door 100. Due to the presence of the time-delay power supply 330, the two electromagnetic releasers 300 can be controlled through one line, simplifying the circuit and operation of manual control.

[0118] By connecting a time-delay power supply 330 to the electromagnetic release 300 of the second door 122, the marine fire and smoke barrier device of this embodiment ensures that both doors close sequentially even in the event of a complete power outage on the vessel, further improving the device's reliability and safety. Furthermore, the use of the time-delay power supply 330 simplifies the circuitry and operation of manual control, improving manual control efficiency. This device effectively addresses the safety hazard of power failure of the smoke-tight door 100 in the prior art, providing a more reliable safeguard for marine fire safety.
