Abstract
The utility model aims at providing a maintenance demolish convenient, do not influence hull structure, improve the bulbous bow device of hull stability. The utility model discloses a toper shell and a plurality of cross slab, it is a plurality of the cross slab is all fixed inside the toper shell, the planking fixed connection of toper shell and bow lower part, the toper shell forms first sealed air cavity with the cooperation of hull planking. The utility model discloses be applied to hull structure's technical field.
Description
Technical Field
The utility model discloses be applied to hull structure's technical field, in particular to bulbous bow device.
Background
As is well known, the bulbous bow is a bulbous projection below the water surface of the bow, a structure for overcoming the resistance of the ship. The size and the shape of the ship body are matched with the ship body, so that the pressure of water can be counteracted, the generated ship waves are small, and the water flow condition near the ship body can be improved, so that the resistance of the ship is reduced. When the ship is designed and the theoretically estimated navigational speed does not meet the design requirement, the water line length can be properly increased to reduce the resistance under the specific condition, and the bow bulb device at the head part just solves the problem, namely the water line length is increased, so that the resistance is reduced, and the rapidity and the economy of the ship are improved. Then the traditional bulbous bow and the hull are integrally formed, so that the maintenance is difficult after the collision and the damage occur, and simultaneously, seawater can easily enter the hull.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide a maintenance demolish convenient, do not influence the hull structure, improve the bulbous bow device of hull stability.
The utility model adopts the technical proposal that: the utility model discloses a toper shell and a plurality of cross slab, it is a plurality of the cross slab is all fixed inside the toper shell, the planking fixed connection of toper shell and bow lower part, the toper shell forms first sealed air cavity with the cooperation of hull planking.
According to the scheme, the bulbous bow structure is independent of the hull by adopting a split design, and the structural strength of the conical shell is improved by arranging the diaphragm plate structures. The first sealed air cavity is formed by matching the conical shell with the outer plate of the ship body, so that buoyancy is provided for the ship, and the stability of the ship body is further improved.
Preferably, a plurality of the diaphragms are arranged in an array along the length direction of the conical shell.
According to the scheme, the supporting points of the conical shell are uniformly distributed, and the structural strength of the conical shell is effectively improved.
Preferably, the outer edge of each diaphragm plate is welded with the conical shell into a whole, and two adjacent diaphragm plates are matched to form a second sealed air cavity.
According to the scheme, the second sealing cavity is formed by matching two adjacent diaphragm plates, so that the effect of providing buoyancy can be still maintained after the area of the conical shell part is damaged.
Preferably, the lower end of the conical outer shell is flush with the bottom of the ship.
According to the scheme, the ship bottom is smoother, and the water flow resistance is reduced.
Preferably, the conical shell and the hull plate are welded into a whole.
It can be seen from the above scheme that the integral connection is firmer by adopting the welding fixation, and the separation can be realized by cutting the welding part when the maintenance is required to be dismantled.
