In order to achieve the purpose, the invention provides a closed stealth bulwark which comprises an outer side wall plate, a top plate and an inner side wall plate, wherein the outer side wall plate, the top plate, the inner side wall plate and a deck are sequentially connected to form a hollow closed cavity.
In the closed stealth bulwark, the outer side wall plate adopts a longitudinal framework type structure; the inner side wall plate is of a transverse framework type structure.
In the closed stealth bulwark, the surface of the outer side wall plate facing the inner side wall plate is longitudinally provided with the reinforcing ribs.
In the closed type stealth bulwark, the reinforcing ribs are of structures with two inclined ends.
The closed stealth bulwark is characterized in that the surface of the inner side wall plate facing the outer side wall plate is vertically provided with a strengthening material.
In the closed stealth bulwark, a first ventilation opening is formed in a deck in the hollow closed cavity, a second ventilation opening is formed in the inner side wall plate, and a grid plate is mounted at the second ventilation opening to form a ventilation enclosure well.
Above-mentioned closed stealthy bulwark, wherein, be equipped with vertical strengthening rib on the surface of lateral wall board towards the inside lateral wall board.
In the closed stealth bulwark, a process plate is arranged on the surface of the inner side wall plate facing the outer side wall plate.
Compared with the prior art, the invention has the beneficial technical effects that:
according to the closed stealth bulwark, the outer side wall plate, the top plate, the inner side wall plate and the deck are used for enclosing a hollow closed cavity, and equipment exposed on the deck at the head part of a ship is covered, so that the stealth capability of radar waves when the ship faces air investigation is improved, and the life and fighting capacity of the whole ship are further improved; meanwhile, the hollow closed cavity coats the wall plate upper framework (the reinforcing ribs 2, the reinforcing material 4 and the vertical reinforcing ribs 6), so that the radar wave hiding capability of the ship in the air during detection is further improved; the closed stealth bulwark adopts the double-layer wall plates, so that the strength of the bulwark is enhanced.
