TECHNICAL FIELD
[0001] The utility model relates to the technical field of ship, especially a novel outdoor anti-pirate inclined ladder of ship superstructure. BACKGROUND
[0002] At present, there are many anti-pirate measures in sea navigation. Before pirates board the ship, there are anti-pirate radar systems, anti-pirate water cannons, anti-pirate gillnets and other equipment to monitor and prevent pirates from boarding. After pirates board the ship, they can be prevented from reaching important areas such as living areas, engine room areas and bridge areas by limiting their activity range. To prevent pirates from reaching the decks of the living areas and the bridge area through the outdoor staircases of the superstructure, the existing anti-pirate staircases are usually outdoor.
[0003] The outdoor anti-pirate staircase sets the rail used to prevent people from falling off the opening as movable, i.e. loosens the fixing device at the bottom of the rail in contact with the deck, blocks the opening on the deck by lowering the rail, and fixes the bottom and top of the rail to prevent pirates on the lower deck from entering the upper deck through the opening.
[0004] However, this anti-pirate staircase has two shortcomings. First, the rail needs to be designed as movable, and the rail on the deck to the upper deck also needs to be detachable. Because of the height, the rail is easily blocked by the upper rail when it is lowered. Only by detaching the rail can the rail be lowered. This makes the structure of the design more complex, and it takes a long time to operate the rail and the rail, which is not conducive to quickly blocking the opening of the rail on the deck when pirates arrive. Second, the fixing device after the rail is lowered is at the bottom and top of the rail, i.e. the two sides of the rail. Pirates may be able to disengage the fixing device by hand or device through the gap in the rail, which is slightly flawed in safety.
[0005] Therefore, the current anti-pirate staircase has the shortcomings of complex structure leading to long operation time and poor safety of the bottom and top of the rail when the rail is lowered. UTILITY MODEL CONTENTS

[0024] The utility model will be described in more detail below with reference to the preferred embodiments and drawings.
[0025] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 Indicated, a new type of ship superstructure outdoor anti-pirate ladder, it includes superlattice 10, deck 20 is provided with passageway 21, superlattice 10 is located at passageway 21 above.The lower deck is provided with lower ladder 30.The deck is also provided with rail 32, the rail is located around the passageway.
[0026] The new type of ship superstructure outdoor anti-pirate ladder also includes the grid 22 that can cover passageway, and the grid 22 is located below superlattice 10.
[0027] The bottom of grid 22 is hinged to deck 20.The hinge of grid 22 and deck 20 is located between the bottom of superlattice and passageway.
[0028] The new type of ship superstructure outdoor anti-pirate ladder also includes hanging component 40;The top of grid 22 is hung in the bottom of superlattice 10 through hanging component.
[0029] The deck 20 is provided with the lock connection component 50 that can lock the top of grid.
[0030] The top of grid 22 is fixed with first eye plate 23 that can be connected with hanging component and lock connection component.
[0031] Hanging component 40 includes chain 41 and hook 42, and the top of chain 41 is fixedly connected to superlattice 10, and hook 42 is connected to the bottom of chain 41.
[0032] Hook 42 is threaded in first eye plate 23.
[0033] The hinge of the bottom of grid 22 and deck 20 is located at one side of passageway 21, and the lock connection component is located at the other side of passageway 21.
[0034] The locking component 50 comprises a second eye plate 51 arranged on the deck 20, and further comprises a locking rod (not shown in the figure) capable of being arranged through the first eye plate 23 and the second eye plate 51.
[0035] The deck 20 is fixed with a water barrier flat iron 24, and the second eye plate 51 is arranged on the side of the water barrier flat iron 24, and the second eye plate 51 and the passage opening 21 are respectively located on the two sides of the water barrier flat iron 24.
[0036] When the grating covers the passage opening, the eye hole of the first eye plate 23 and the eye hole of the second eye plate 51 are on a straight line. The locking rod can pass through the eye hole of the first eye plate and the eye hole of the second eye plate, so as to lock the grating on the deck.
[0037] The width of the upper part of the grating 22 is smaller than the width of the lower part of the grating 22. The water barrier flat iron 24 is provided with a recess 25 capable of accommodating the upper part of the grating.

When pirates come, the grating needs to cover the passage opening, the hook is separated from the top of the grating, the grating is rotated around the hinge at the bottom of the grating, and the passage opening can be covered. During the process of placing the grating, the movement of the grating in the front, back, left and right directions of the passage opening can be limited. After the grating covers the passage opening, the eye hole of the first eye plate on the grating and the eye hole of the second eye plate on the deck are on a straight line, and the locking rod passes through the eye holes, so that the grating and the deck are firmly fixed. The locking rod can be an iron rod.
[0040] The first eye plate on the grating plays two roles: first, cooperates with the hanging component to hang the grating below the upper stair; second, cooperates with the locking component to lock the grating on the deck.
[0041] When pirates come, the hook is separated from the grating, and the grating is locked on the deck, the operation is simple, and the required time is very short; it is very suitable for emergency operation of anti-piracy
[0042] Since the second eye plate for fixing the grating on the deck is located at the uppermost of the lower stair and is away from the lower stair at a certain distance, and the lower stair has a certain slope, it is difficult for pirates to pass through the gap of the grating on the lower stair with hands or devices to unlock the locking component on the other side of the water barrier flat iron, so that the safety of the utility model is improved.
[0043] The utility model discloses simple structure, convenient operation, therefore save time, be applicable to the emergency operation of anti -piracy, the safety has also obtained the promotion, and the security greatly increases.
