[0002] Fire is one of the damages that ships often encounter. Smoke is an important product of the fire combustion process. High-temperature smoke not only accelerates the spread of fire, but also causes casualties due to its own toxicity, and reduces visibility, affecting people's escape. Statistics show that more than 80% of deaths in fires are caused by smoke. At present, in-depth research has been conducted on fire smoke control systems for buildings at home and abroad, but there is little research on smoke control technology for ship cabins.

[0003] The ship's wheelhouse is an important control compartment on the ship. When a fire occurs, it is necessary to focus on smoke control in this compartment to prevent secondary disasters.

[0004] The ship's driving cab in the prior art usually adopts a filtering smoke elimination system. When the ship's driving cab area is partially filled with or has been filled with smoke, the filtering smoke elimination system in the prior art passively eliminates the smoke in the control area through filtering, which takes a long time, does not completely remove the smoke, and the filter element of the system needs to be replaced frequently, which is inconvenient to maintain and use.

[0030] Furthermore, the outdoor electric control cabinet 5 and the power module 7 are both installed on the wall of the ship cabin area 9 away from the cab entrance 10, and the power module 7 is arranged adjacent to the outdoor electric control cabinet 5.

[0031] Furthermore, the installation position of the indoor electric control cabinet 4 on the wall of the protected cab area 8 corresponds to the installation position of the power module 7 on the wall of the ship cabin area 9.

[0034] Furthermore, a manual operation button is arranged on the cabinet door of the outdoor electric control cabinet 5 .

[0035] Embodiment 2. This embodiment provides a layout structure of a positive pressure smoke prevention system for a ship's cab, in which a mechanical pressurized fan, an indoor electric control cabinet, and an indoor sensor module are arranged in the protected cab; one end of the air supply pipe system is connected to the area outside the ship's cabin, and the other end is connected to the mechanical pressurized fan; the outdoor electric control cabinet, the outdoor sensor module, and the power supply system are arranged in the ship's cabin area (outside the protected cab); the sensor modules are distributed in the protected passage and in the ship's cabin area near the protected cab.

[0036] Furthermore, both the indoor and outdoor sensor modules are connected to the indoor electric control cabinet, which is connected to the mechanical pressurized fan; the information of the internal and outdoor sensor modules is summarized in the indoor electric control cabinet, and the mechanical pressurized fan is finally started and stopped by the indoor electric control cabinet.

[0037] Furthermore, the mechanical pressurized fan is also connected to the outdoor electric control cabinet. As an emergency measure, when a fire occurs and smoke is generated, if the indoor electric control cabinet fails to start the fan, the fan can be started manually through the outdoor electric control cabinet.

[0038] Furthermore, the internal and outdoor sensor modules specifically include an air pressure sensor, a smoke sensor, a temperature sensor, and an air quality sensor.

[0039] Furthermore, when the system is working, a continuous relative positive pressure area can be formed in the protected cab to prevent smoke from entering and ensure that the temperature, oxygen and visibility in the protected area meet the escape and rescue buffer requirements.

[0040] There are three main working modes:

[0041] The first is the all-weather real-time positive pressure mode, that is, based on the power supply of the power system, the electric control cabinet controls the start and stop of the mechanical pressurization fan to continuously press the air outside the ship cabin into the protected cab, and continuously maintain a relative positive pressure state in the protected cab, so that the smoke generated by the fire cannot enter the protected cab area, which can provide a buffer for personnel to escape or rescue;

[0042] The second mode is the linkage positive pressure mode, that is, once a fire occurs and smoke is generated, the internal or outdoor sensor module first detects the smoke, and the sensor module feeds back the information to the indoor electric control cabinet, which starts the mechanical pressurization fan, and the air is continuously pressed into the protected cab from outside the ship cabin through the air supply pipeline system. The protected cab quickly forms a relatively positive pressure area, so that the smoke generated by the fire cannot enter the protected cab area, which can provide a buffer for personnel to escape or rescue;

[0043] The third mode is the emergency control positive pressure mode, that is, once a fire occurs and smoke is generated, the internal or outdoor sensor module fails, no smoke is detected, and the indoor electrical control cabinet does not start the mechanical pressurization fan, the outdoor electrical control cabinet can be manually operated to manually start the mechanical pressurization fan, and the air is continuously pressed into the protected cab from outside the ship's cabin through the air supply pipeline system. A relatively positive pressure zone is quickly formed in the protected cab, and the smoke generated by the fire cannot enter the protected cab area, which can provide a buffer for personnel to escape or rescue; ultimately, the purpose of smoke prevention in the cab can be achieved.

[0044] Furthermore, all parts involved in this application that are not described in detail are the same as the prior art or are implemented using the prior art.

[0045] In summary:

[0046] 1. The utility model provides a layout structure of a positive pressure smoke prevention system for a ship's wheelhouse. By installing a mechanical pressurized fan in the protected wheelhouse area, combined with the reasonable layout of air supply pipelines, indoor and outdoor sensor modules and electric control cabinets, it can respond quickly when a fire occurs on a ship and effectively prevent smoke from entering the wheelhouse. The overall layout of the structure is easy to install and is convenient for operators to maintain and use.
