Description

Ship with Y-shaped chain locker structure

Technical Field

The application belongs to the technical field of manufacturing of ship bow doors, and particularly relates to a ship with a Y-shaped anchor chain cabin structure.

Background

The hawser serves as one of the important components of the mooring system, which functions to store the hawser of the whole vessel and to sink the anchor and the hawser into the water when it is necessary to break down the anchor, providing the vessel with traction for securing. The anchor machine, the anchor discarding device, the anchor chain pipe and other structures are usually arranged in the anchor chain cabin to finish the pulling operation of the anchor chain, if the cabin capacity is insufficient, the anchor chain cannot be fully retracted, namely the anchor can be suspended outside a ship and cannot be tightly attached to the anchor lips, and when the storms are large, the anchor can strike the outer plate of the ship body, so that the risk is high.

In ship design, the anchor chain cabins generally appear in pairs and are symmetrically arranged at the front ends of the anti-collision cabins in a left-right mode, the left-right anchor chain cabins are completely separated, the vertical direction is kept unchanged, the anchor chain cabins should be kept watertight, the upper ends of the anchor chain cabins extend to the weather deck, the lower ends of the anchor chain cabins fall on a certain deck platform, and the lower ends of the anchor chain cabins are provided with sludge cabins. In order to meet the sailing performance requirement of the ship, the bow line type is generally changed greatly relative to the bow, and most of the cross sections of the bow parts of the ship are characterized by being wide in upper part and narrow in lower part. For large and medium vessels, the head is relatively bulky, and the separate arrangement of the left and right hawser is generally not problematic. For small and medium-sized ships with compact heads, if the left chain cabin and the right chain cabin are arranged separately on the basis of meeting mooring arrangement, the structural design requirement can be difficult to achieve due to insufficient transverse width of the lower end of the chain cabin. For the ship with compact head, if the left and right chain cabins are not required to be kept to be arranged separately and the chain cabins are arranged vertically, the lower structure design becomes extremely complex due to the limited space below the chain cabins, and the manufacturing difficulty is increased.

CN 213594456U discloses a chain cabin breaking through the cylinder and mutually independent type of the traditional chain cabin, on the basis of meeting the cabin capacity requirement of the chain cabin and the convenience of use, the problem that the chain cabin with a circular section is intersected with the bulkhead and the outer plate at a small angle is effectively solved, and the difficulty of ship construction and construction is reduced. According to the scheme, the anchor chain cabin is simply folded to the middle of the ship body, the mooring arrangement of the mooring deck needs to be adjusted, the original mooring arrangement of the mooring deck is changed, and the inclined plane plate (comprising the left lower end wall and the right lower end wall) parallel to the outer plate of the ship body is used as a part of the side wall of the anchor chain cabin in the scheme, so that the ship body cannot be applied when the structure of the ship body is in an irregular arc shape, and the use difficulty is increased. And the ship body structure needs to be accurately matched with the ship body structure, so that the assembly difficulty is high.
