Description

Technical Field

[0001] The utility model relates to the technical field of ship engine room monitoring, in particular to a ship engine room monitoring fire alarm device. Background Art

[0002] The ship's engine room refers to the area in the ship's interior space used to install and operate various mechanical equipment. This area generally includes the main engine, auxiliary engine, generator, oil-water separator, water pump, air conditioning equipment and other machinery and equipment. The engine room is also equipped with various ship systems, such as power supply, water supply, oil supply and ventilation systems, to ensure the normal operation and safety of the ship.

[0003] In order to ensure safety, fire monitoring is usually carried out on the oil tanks in the ship's engine room. However, the current monitoring devices are usually equipped with fire extinguishing devices when in use, but they can only spray water at one angle, which will affect the effect of fire extinguishing. For this reason, we propose a ship engine room monitoring fire alarm device to solve the above problem. Utility Model Content

[0010] In a further embodiment, a fixing plate is installed on the back of the water tank, and a group of fixing holes are opened on the front of the fixing plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] This device cooperates with the smoke sensor and the alarm. The smoke sensor can monitor the smoke concentration. If the smoke concentration is too high, it indicates a fire. At the same time, the alarm will sound an alarm to remind the people on board. Through the cooperation of the pump body, water suction pipe, telescopic pipe and nozzle, the work of the pump body can transport water to the nozzle, and the nozzle will spray water onto the fire, so as to achieve the effect of extinguishing the fire. Through the cooperation of the motor, threaded rod, movable plate and support plate, the work of the motor can make the movable plate rise and fall on the threaded rod, and the movable plate will drive the support plate when it moves. The support plate can push or pull the nozzle, thereby realizing the adjustment of the nozzle angle. The nozzle can spray at multiple angles, further ensuring the effect of fire extinguishing.
