Submersible stern structure

Abstract

The invention relates to a submersible stern structure which comprises a shell. The tail end of the shell is sequentially connected with a stabilizer fin structure and a vertical propeller. The stabilizer fin structure comprises a vertical stabilizer fin and a horizontal stabilizer fin which are distributed in a T-shaped mode. A penetrating rotating shaft is arranged in the horizontal stabilizer fin. The two ends of the rotating shaft are connected with movable fins which are connected with main propellers. By means of the submersible stern structure, the transverse shaking of the underwater submersible can be restrained, the direct route stability of the submersible is ensured, assembling difficulty is low, the axis direction of the main propellers is consistent with the advancing and retreating directions, the thrust of the main propellers is effectively used, and it is ensured that the submersible has strong driving force.

Description

technical field [0001] The invention relates to a submersible, in particular to a submersible stern structure. Background technique [0002] The arrangement structure of the submersible's stern stabilizer wing plays a key role in the navigation stability of the submersible, which can effectively restrain the underwater roll of the submersible and ensure the direct flight stability of the submersible. For a manned submersible with a small main scale, due to its weak resistance to external force interference, a reasonable design of the arrangement of the stabilizer fins is crucial to the safety of the submersible. The stabilizer wings on the submersible mainly have T-shaped arrangement, I-shaped arrangement, ten-shaped arrangement and X-shaped arrangement. The tail fins of Russia's "Peace 1" and "Peace 2" are T-shaped arrangements, and the French "Nautilus" The stabilizing wings of the manned submersible are arranged in an I shape. The stabilizing wings of Japan's "Deep Sea 65...

Problems solved by technology

The stabilizer wings on the submersible mainly have T-shaped arrangement, I-shaped arrangement, ten-shaped arrangement and X-shaped arrangement. The tail fins of Russia's "Peace 1" and "Peace 2" are T-shaped arrangements, and the French "Nautilus" The stabilizing wings of the manned submersible are arranged in an I shape. The stabilizing wings of Japan's "Deep Sea 6500" manned submersible are in a ten-shaped arrangement, while the stabilizing wings of my country's Jiaolong manned submersible adopt an X-shaped arrangement. The propeller is distributed between the x-shaped stabilizers of the submersible’s stern cone. Compared with the T-shaped arrangement, I-shaped arrangement, and ten-shaped arrangement, this kind of stabilizer and thruster structure can improve the maneuverability of the submersible, and can avoid thrusters The situation of being bruised by the mother ship and entangled with floating objects in the water occurs, but this arrangement has high requirements for the installation of stabilizers and thrusters, and the assembly is difficult. Each thruster actually provides only the power for the submersible to move forward and backward. About 50% of the thrust, the thrust of the main thruster cannot be effectively used, and the power consumption of the submersible battery is seriously wasted
