Technical Field
[0001] The utility model relates to the technical field of spray fire extinguishing, in particular to a ship leakproof spray fire extinguishing structure. Background Art
[0002] Ships are man-made vehicles that mainly operate in geographical waters. In addition, civilian ships are generally called ships, military ships are called warships, and small ships are called boats or boats. They are generally called ships or boats. The interior mainly includes accommodation space, support structure and drainage structure, and has a propulsion system that uses external or self-contained energy. The appearance is generally a streamlined envelope that is conducive to overcoming fluid resistance. The materials are constantly updated with the advancement of science and technology. In the early days, they were natural materials such as wood, bamboo, and hemp. In modern times, they are mostly steel, aluminum, fiberglass, acrylic and various composite materials.
[0003] The fire sprinkler system is a fire extinguishing device and a widely used fixed fire fighting facility. It has the characteristics of low price and high fire fighting efficiency. According to different functions, it can be divided into two forms: manual control and automatic control. The system is equipped with an alarm device, which can automatically sound an alarm when a fire occurs. The automatically controlled fire sprinkler system can automatically spray and work in conjunction with other fire fighting facilities, so it can effectively control and extinguish early fires.
[0004] The characteristics of ship fires can be summarized into several aspects: 1. The fire point is hidden and difficult to find; 2. After the fire, the fire spreads rapidly; 3. The cabin structure is complex and the fire is difficult to extinguish; Based on the above characteristics, it is best to put out the fire in the early stage of the fire to quickly extinguish the flames and prevent the fire from spreading. Therefore, a rotatable fire extinguishing device with fixed-point spraying is needed to prevent the electronic instruments and equipment from being damaged again after contacting water, causing unpredictable losses.
[0005] At the same time, when the existing sprinkler fire extinguishing structure is used in a ship, the sprinkler structure energy saving may leak, causing water droplets to fall, affecting special cabins such as ammunition depots. By the time the leak is repaired, the cabin has already been affected. Utility Model Content

A groove is provided in the middle of the bottom of the shell 1, and a hidden plate 15 is installed in the groove. A connecting line 18 is installed between the bottom of the shell 1 and the hidden plate 15. The connecting line 18 can suspend the hidden plate 15. When a fire occurs, the driving motor 2 is started to drive the screw 3 to rotate, thereby driving the sliding plate 4 to descend. Then the spray structure 7 pushes the movable plate 9 and the hidden plate 15 open and exposes them from the groove, so that the spray range of the spray structure 7 is not restricted, the spray range of the spray structure 7 is expanded, and the fire extinguishing effect is improved.
