The strengthening parts include a circle of reinforcing plates fixedly arranged on the inner wall of the steel outer plate, a first tread plate fixedly connected to the periphery of the steel outer plate, and at least two second tread plates fixedly arranged on the door frame. This marine fire door enhances the overall strength of the door leaf through the protection member fixedly connected inside the steel outer plate, and both the door leaf and the door frame are filled with fireproof marine rock wool, so that both the door leaf and the door frame have good fireproof benefits and simple structures, and the interior of the door leaf is filled and connected tightly. When a fire occurs in the above device, the handle gets hot and the hatch door cannot be opened in time. Therefore, it is urgent for those skilled in the art to solve the above technical problems. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that in the prior art, when the handle of the above device is too hot, the hatch door cannot be quickly opened, and opening the door rashly may cause burns.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A quick-opening fire and watertight hatch door is used to quickly open the cabin door through a control panel when the door handle cannot open the hatch door in extreme situations. It includes a drive motor, a door panel, a handle, an observation window, a control panel, and an interlocking mechanism; the drive motor is engaged with the lock core of the handle through gears, the drive motor is installed inside the door panel, the observation window and the control panel are installed on the front of the door panel, the control panel is electrically connected to the drive motor, the handle is arranged on the front and back of the door panel, and the interlocking mechanism is arranged inside the door panel.

[0007] Further, a transmission sawtooth is provided at the end of the drive motor, the transmission sawtooth is engaged with the gear of the lock core, and the transmission sawtooth slides up and down under the drive of the drive motor, driving the handle lock core 111 to rotate through the engaged gears.

[0008] Driving the transmission sawtooth to rotate quickly by the drive motor can quickly unlock the handle lock core, thereby quickly opening the hatch door, winning precious time for emergency evacuation. This design makes the process of opening the hatch door simpler and faster, without complex operation steps. Just start the drive motor through the control panel. In emergency situations, especially when the door handle is overheated, the crew can directly operate through the control panel without manually turning the handle, reducing the need for manpower. In emergencies such as fires, the crew can operate through the control panel without directly contacting the overheated handle, avoiding the risk of burns. The control panel can be located in a safe position, allowing the hatch door opening procedure to be started from a distance, and can be operated even if the environment near the hatch door is unsafe. An automated control system can be integrated, for example, linked with a fire alarm system to automatically trigger the opening of the hatch door, further improving safety.

[0009] Further, the interlocking mechanism is connected to the handle, the interlocking mechanism is rotatably arranged inside the door panel. When the handle is locked, the interlocking mechanism is stuck at the connection between the door panel and the hull. When the handle is released, the interlocking mechanism rotates and retracts into the door panel.

[0010] The interlocking mechanism is clamped between the door panel and the hull when the handle is locked, ensuring that the hatch door is in a fully closed state, improving the watertightness and airtightness of the hatch door, thus enhancing the fireproof and watertight performance. When the handle is released, the interlocking mechanism can quickly rotate and retract into the door panel to achieve the quick opening of the hatch door, which is very important for emergency evacuation. This design makes the process of opening the hatch door simpler and faster. It only needs to start the driving motor through the control panel, without complex operation steps. In case of emergency, especially when the door handle is overheated, the crew can directly operate through the control panel without manually turning the handle, reducing the demand for manpower. Operating the interlocking mechanism through the control panel can quickly complete the opening of the hatch door, winning precious time for emergency evacuation. The design of the interlocking mechanism makes the opening and closing actions of the hatch door more stable and reliable, reducing the risk of the hatch door malfunctioning due to mechanical failures. The design of the interlocking mechanism is relatively simple, facilitating maintenance and inspection, and helping to ensure that the system is always in good working condition.

[0011] Furthermore, the observation window is composed of explosion-proof glass and is provided at the upper part of the door panel.

[0012] Using explosion-proof glass can prevent flames from penetrating the observation window, thus protecting the people inside the cabin from the impact of fire. The observation window provided at the upper part of the door panel allows the crew to check the inside of the cabin without opening the hatch door, which is very useful for confirming whether there are people inside the cabin or evaluating the fire situation. The presence of the observation window enables the crew to quickly judge whether it is necessary to open the hatch door for rescue or take other actions, helping to make quick decisions. In case of emergency, the observation window can help the crew confirm the situation inside the cabin and avoid the additional risks brought by blindly opening the hatch door. The information obtained through the observation window can help the crew determine whether emergency rescue resources are needed, so as to reasonably allocate limited rescue forces. Explosion-proof glass is usually more durable than ordinary glass, which means that the maintenance cost of the observation window is lower and it is not easily damaged. Using explosion-proof glass meets the requirements of the International Maritime Organization (IMO) and other relevant safety regulations, ensuring that the ship meets safety standards.

[0013] Furthermore, the control panel is provided below the observation window. A quick-opening button is provided on the control panel. The quick-opening button is electrically connected to the driving motor, and the driving motor is electrically connected to an external power source.

[0014] The quick - release button enables the rapid startup of the drive motor in case of an emergency, thus quickly opening the hatch door and winning precious time for personnel evacuation. The control panel is located below the observation window, facilitating the operator to easily press the quick - release button while observing the situation inside the cabin. The operation is intuitive and convenient. In the case where the door handle overheats or cannot be manually opened, the crew can operate through the control panel without directly touching the overheated handle, avoiding the risk of scalding. The control panel can be located in a safe position, allowing the hatch door opening procedure to be initiated from a distance, enabling operation even when the environment near the hatch door is unsafe. It can be integrated with an automated control system, such as being linked with the fire alarm system to automatically trigger the opening of the hatch door, further enhancing safety. The control panel can be integrated with a display screen or indicator lights to provide real - time feedback on the door's status, facilitating monitoring and management. The design of the control panel is relatively simple, facilitating maintenance and inspection.

[0015] Furthermore, an asbestos board is laid inside the door panel.

[0016] The asbestos board has good heat - insulating properties and can effectively block heat transfer, protecting the drive motor, control panel, and circuit from the influence of high temperatures. Especially in the event of a fire, asbestos is a natural fire - proof material that can effectively prevent flames from penetrating the door panel and protect the electronic components inside the door from fire attacks. The asbestos board laid inside the door panel can form a barrier to prevent high temperatures from causing circuit short - circuits or damage, ensuring that the control system can still operate normally in case of an emergency. By reducing the impact of heat on the drive motor, control panel, and circuit, the asbestos board helps to extend the service life of these key components. In the event of a fire, the asbestos board can provide the crew with additional time to evacuate safely while protecting the critical electrical systems from being damaged, thus ensuring that the hatch door can be opened normally.

[0017] The utility model has the following beneficial effects:

[0018] 1. With the quick - release button on the control panel located below the observation window, the crew can quickly start the drive motor in an emergency, enabling the rapid opening of the hatch door, winning precious time for personnel evacuation, and making the operation more intuitive and convenient.

[0019] 2. In the case where the door handle overheats or cannot be manually opened, the crew can operate through the control panel without directly touching the overheated handle, avoiding the risk of scalding. The control panel can be located in a safe position, allowing the hatch door opening procedure to be initiated from a distance.

[0020] 3. The interlocking mechanism is connected to the handle and is clamped at the connection between the door panel and the hull when the handle is locked, ensuring that the hatch door remains tightly closed under non - emergency conditions. When the handle is released, the interlocking mechanism can quickly rotate and retract into the door panel, enabling the rapid opening of the hatch door and ensuring reliable opening of the hatch door in an emergency.

[0027] The present utility model will be further described in detail below in conjunction with the drawings and specific preferred embodiments.

[0028] In the description of the present utility model, it should be understood that the orientation or positional relationships indicated by the terms "left side", "right side", "upper part", "lower part", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. "First", "second", etc. do not represent the importance of the components, so they cannot be understood as limitations to the present utility model. The specific dimensions adopted in this embodiment are only for illustrating the technical solution by way of example, and do not limit the protection scope of the present utility model.

[0029] Embodiment 1: Refer to Figure 1 and Figure 2, it can be seen that the quick-opening fire and watertight hatch is installed in the cabin. The door handle of the existing cabin hatch will become hot and difficult to open quickly during a fire, which affects the rescue speed. Therefore, in order to improve the opening speed of the hatch during a fire, a quick-opening fire and watertight hatch is proposed, including a door panel 1 that constitutes the main body of the device. Handles 11 are provided on the front and back of the door panel 1. An observation window 12 is provided in the upper part of the front of the door panel 1. A control panel 13 is arranged at the lower right of the observation window 12. A driving motor 2 is connected to the lock core 111 of the handle 11. The lock core 111 is driven to rotate by the driving motor 2, avoiding scalding caused by manually opening the hatch. During use, the staff can control the driving motor 2 to open through the control panel 13, and the lock core 111 is controlled by the driving motor to rotate, thereby opening the door panel 1, improving the opening efficiency of the door panel 1 and avoiding scalding of personnel caused by the overheating of the handle 11 during a fire;

[0030] Example 2: Compared with Example 1, in order to quickly open the lock core 111 of the handle 11 and thus open the hatch, refer to Figure 3 , Figure 4 and Figure 5 , it can be seen that by setting a transmission saw tooth 21 at the end of the driving motor 2 and a gear meshing with the transmission saw tooth 21 on the lock core 111, when the driving motor 2 rotates, the output gear shaft of the driving motor 2 drives the transmission saw tooth 21 to move in the vertical direction. When the transmission saw tooth 21 moves up and down, the lock core 111 will rotate driven by the gear, and the lock core 111 drives the interlocking mechanism 3 to separate from the cabin body, thereby loosening the hatch from the cabin body. In order to ensure the airtightness of the hatch, a sealing strip can also be set at the place where the inner wall of the door panel 1 contacts the cabin body. The hatch is quickly opened through the driving motor 2 to achieve rapid opening of the hatch.

[0031] Example 3: Compared with Example 1 and Example 2, the observation window 12 is convenient for observing the internal situation of the cabin body. However, in high-temperature situations, ordinary glass may break, causing the internal fire to spread outside the cabin or the external fire to spread into the cabin. Therefore, the observation window 12 is made of explosion-proof glass, which can prevent the spread of fire during a fire, and the explosion-proof glass has extremely high strength, avoiding damage by external forces and improving the safety of the cabin.

[0032] Example 4: The driving motor 2 is connected to an external power source through an electric wire. During a fire, if the electric wire burns out, it will affect the opening of the hatch. Therefore, the driving motor 2 is electrically connected to an external power source on the one hand and also connected to a backup power source inside the door panel 1. In the case of damage to the external power source, the driving motor 2 can operate normally through the internal power source, improving the fault tolerance of the driving motor 2.

[0033] Example 5: In order to quickly start the driving motor, a quick-opening button is set on the control 13 panel. The quick-opening button is electrically connected to the driving motor 2 to directly control the opening and closing of the driving motor 2;

[0034] During use, the control panel 13 is located below the observation window 12, facilitating easy operation by the operator while observing the situation inside the cabin. The quick-opening button is designed in a conspicuous color for easy identification and operation. The control panel 13 also includes necessary indicator lights or displays for showing the status of the cabin door. The quick-opening button is directly connected to the drive motor 2 through an electrical circuit. When the quick-opening button is pressed, an electrical signal is directly transmitted to the drive motor 2, and the drive motor 2 operates. By meshing the transmission saw teeth 21 with the gear of the lock core 111, the handle 11 and the lock core 111 are driven to rotate, realizing the quick opening of the cabin door.

[0035] Embodiment Six: To protect the drive motor 2 and the circuit inside the door panel 1, an asbestos board is laid inside the door panel 1. When laying the asbestos board, a reserved space for the backup power supply and the drive motor is provided.

[0036] An asbestos board is laid inside the door panel 1 to cover most of the internal area, ensuring full protection of the drive motor 2 and the circuit. When laying the asbestos board, sufficient space needs to be reserved to accommodate the drive motor 2 and the backup power supply. According to the size of the drive motor 2 and the size of the backup power supply, appropriate space is reserved on the asbestos board to ensure that the drive motor 2 and the backup power supply can be installed smoothly and there is enough space for necessary heat dissipation. The drive motor 2 is installed in the reserved space, ensuring a certain distance from the asbestos board for heat dissipation. The backup power supply is installed and a reliable electrical connection is ensured between it and the drive motor 2 so that it can continue to supply power when the main power fails. The asbestos board is laid around the circuit inside the door panel 1 to reduce the impact of high temperature on the circuit. High-temperature-resistant wires and cables are used and it is ensured that these wires and cables do not directly contact high-temperature parts. The asbestos board has good heat insulation performance and can effectively block heat transfer, protecting the drive motor 2 and the circuit from high temperature. Especially in the case of a fire, the asbestos board is a natural fireproof material and can effectively prevent the flame from penetrating the door panel 1, protecting the electronic components inside the door from the flame. The asbestos board laid inside the door panel 1 can form a barrier to prevent the high temperature from causing a short circuit or damage to the circuit, ensuring that the control system can still work normally in an emergency. By reducing the impact of heat on the drive motor 2 and the circuit, the asbestos board helps to extend the service life of these key components.

[0037] The preferred embodiments of the present invention are described, however, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all belong to the protection scope of the present invention.
