Embodiment 1

[0079] see Figure 1~5 , this example illustrates the realization method of the present invention with the 60m semi-submerged ship as an example. The design of this project requires a maximum diving depth of 50m. In addition to conventional towage work, missiles can also be launched underwater. Ship main body 1 is long 60m in this example, wide 35m, molded depth 6m. Large fixed pontoon 2 is long 8m, wide 5m. The floating island frame 3 of the frame-type floating island with airbag 5 is 8m long and 6m wide, and each layer is placed with a diameter of 2m and 512 special high-pressure airbags with a height of 15m. When the semi-submersible boat dives, due to the pressure of the external seawater, it is necessary to consider the pressure difference of the internal pressure when inflating. Because the gas pressure inside the airbag 5 is consistent in the height direction, but the external water pressure decreases with the increase of the height, so the length of the airbag 5 sho...

Embodiment 2

[0081] This embodiment introduces a method for controlling the lifting of a semi-submersible ship, which respectively includes controlling the submerging action and the rising action of the semi-submersible ship;

[0082] dive:

[0083] a. Seal and fix both ends of the airbag 5 on the airbag tip slot 9 corresponding to the fixed horizontal truss plate 8 of the airbag, wherein the ferrule-type inflation and discharge pipe joint of the airbag 5 is airtightly connected with the hole of the fixed water balance plate of the airbag 5, and then Connect the trachea to the pore, and then use the air source to inflate the airbag 5, and stop inflating when the shape of the airbag 5 reaches the nominal size;

[0084] b. Fix at least one intermediate reserved interface of the airbag 5 capsule body to the adjacent truss structure and / or limit rope 7 by a fixing member, so as to ensure that the airbag 5 will not slide in the height direction;

[0085] c. Restart the inflation action of the ...

Abstract

The invention relates to the field of ship design and manufacturing, in particular to a frame type floating island with an air bag (5). The floating island comprises a floating island frame (3) and the air bag (5) fixedly mounted on the floating island frame (3). The air bag (5) comprises a clamping sleeve type inflation and deflation pipe connector which is connected with an air source through an air pipe. The invention further relates to the semi-submerged ship. The semi-submerged ship comprises a main ship body, a large fixed floating box (2) and the frame type floating island with the air bag (5). The invention further relates to a semi-submerged ship lifting control method. The semi-submerged ship has the beneficial effects that the contradictory relation among the submerging depth, the overall gravity center of the semi-submerged ship and the windward side of the device can be effectively solved, the overall gravity center of the semi-submerged ship can be effectively lowered, the windward side of a floating island can be greatly lowered, the maximum submerging depth of the semi-submerged ship is effectively increased, meanwhile, the body weight and the construction cost of the semi-submerged ship are reduced, and the safety of ship operation is improved.

Description

technical field [0001] The invention relates to the field of ship design and manufacture, and relates to a semi-submersible ship, in particular to a frame-type floating island with an air bag, and a semi-submersible ship equipped with the frame-type floating island. Background technique [0002] Semi-submersible ship, also known as semi-submersible mother ship, is a special engineering ship for the transportation of large structures at sea. Its main working process is: first, make the semi-submersible ship dive to the required draft, float the cargo to be loaded above the main deck of the ship, and then float up. After fixing the cargo to the destination, the ship is sunk again to the required depth, and the loaded cargo is disassembled and floated out. In order to complete the above actions, there are usually multiple ballast tanks inside the hull, and the diving and floating during loading and unloading operations are completed by injecting ballast water and discharging b...
