[0001] The present invention relates to the technical field of watertight bulkheads, in particular to longitudinal watertight bulkheads of cruise hubs. Background Art

[0002] A watertight bulkhead is a bulkhead that remains impermeable under a specified pressure. It divides the interior of a ship into several sealed compartments (or compartments) to prevent flooding from one compartment into other compartments in the event of a marine disaster. This ensures the ship's buoyancy and stability after damage, making it unsinkable.

[0003] On the one hand, current ships do not have such large scales, and on the other hand, they are supported by strong components in the horizontal direction. However, the main body of the mother ship of the hub station is concave in the middle of the ship width direction, and ballast tanks and activity space must be set up. There is no space to arrange a strong horizontal frame with sufficient support. Based on the shortcomings of existing technology, the present invention designs a longitudinal watertight bulkhead for the cruise hub station. Summary of the Invention

[0029] See also Figures 4-6 The multiple branch structures 8 include fixed columns 81, which are fixed to the outer surface of the main deck pillar 7 through a hoop. Four hinge blocks 82 are installed on the outer surface of the multiple fixed columns 81, and hinge rods 83 are hinged inside the four hinge blocks 82. A sleeve column 84 is installed at one end of the multiple hinge rods 83, and a telescopic column 85 is slidably installed inside the sleeve column 84.

It can not only reduce the static water bending moment of the hull beam and reduce the weight of the entire ship structure, but also effectively control the deformation of the hull beam. When welding the telescopic column 85, by using a hexagonal wrench to insert the fastening bolt 87 and rotate the fastening bolt 87, the device can be made The fastening bolt 87 is loosened from the threaded groove column 86. At this time, the telescopic column 85 can be partially pulled out from the sleeve column 84, and then the head of the telescopic column 85 can be welded to the main deck to adapt to main decks of different sizes and thicknesses. At the same time, by using a hexagonal wrench to insert into the inner hexagonal slot 92 and rotate it, the threaded rod 91 is rotated. Due to the limitation of the limiting rod 95, the threaded block 93 can drive the clamping block 94 to move horizontally on the outer surface of the threaded rod 91, thereby allowing the clamping block 94 to disengage from the clamping slot 89. At this time, the welding angle of the sleeve column 84 and the telescopic column 85 can be adjusted, and it can be flexibly adjusted according to the layout of the main deck. At the same time, the telescopic column 85 is pulled out of the sleeve column 84, which can effectively transmit the non-uniform load transmitted to different areas of the main deck.
