TECHNICAL FIELD
[0001] The utility model belongs to shipbuilding technical field, specifically related to a kind of LNG ship anti-pirate door device. BACKGROUND
[0002] For a long time, there are pirate activities in many international navigation waters around the world, and pirate hijacking of ships frequently occurs; LNG ship as a kind of marine transportation tool for transporting liquefied natural gas, inevitably passes through the pirate activity area during ocean navigation, which poses a great threat to the lives of crew members and the interests of shipowners. Generally, a "safe room" will be set up on the ship as a pirate-proof place to serve as an emergency temporary shelter when passing through the pirate-infested area. The door is the key part of the pirate-proof place on the ship, and also the weak link. To meet the requirements of fire rating, the elevator at the engine room control room of the LNG ship is usually an A60 or A0 fire door. When the control room is used as a pirate-proof place, the strength of the fire door cannot effectively prevent and delay the entry of pirates. SUMMARY
[0003] The utility model aims at overcoming the deficiencies in the prior art, and provides an LNG ship anti-pirate door device. The utility model is convenient and fast to use. When the anti-pirate door is closed, the bolt quickly fixes the position of the anti-pirate door. Then, the inclined wedge is inserted into the card slot by rotating the handle, so as to achieve the purpose of locking and closing the anti-pirate door, and effectively prevent pirates from entering the control room.
[0004] To achieve the above-mentioned utility model purposes, the technical solutions provided by the utility model patent are as follows:
[0005] An LNG ship anti-pirate door device, which comprises a frame module and a locking module. The frame module is installed on a steel enclosure wall.

[0006] Further, the door panel is in the shape of a cuboid. The thickness of the door panel is 8mm. A plurality of reinforcing ribs are arranged in parallel on the door panel. A plurality of handles are arranged on the door panel.
[0007] Further, the handle controls the opening and closing of the door panel. The handle is provided with an inclined wedge at one end. A card slot is arranged on the door frame corresponding to the handle. When the handle is rotated, the inclined wedge on the handle is clamped in the card slot, so as to fixedly connect the door panel and the door frame.
[0008] Further, the door plate bottom is provided with a bolt, when the door plate is closed, the door plate lower end ground is provided with a bolt hole, the bolt on the door plate is inserted into the bolt hole.
[0009] Further, the door plate and the door frame are connected through a plurality of hinge mechanisms, the hinge mechanism comprises a fixed plate, a connecting plate and a filler, the fixed plate is vertically welded on the door frame, the connecting plate is connected and fixed with the door plate, the connecting plate is connected with the fixed plate, and the filler is arranged in the groove at the connecting position of the door plate and the door frame.
[0010] Based on the above technical scheme, the LNG ship anti-pirate door device has the following technical advantages after practical application:
[0011] 1. The anti-pirate door device of the LNG ship is convenient and fast to use, when the anti-pirate door is closed, the bolt quickly fixes the position of the anti-pirate door, and then the rotating handle is used to make the inclined wedge be clamped in the clamping groove, so that the anti-pirate door is locked and closed, and the pirates are quickly and effectively blocked from entering the control room.
