Submersible stern part structure

Abstract

The invention discloses a stern structure of a diving instrument, in particular to an arranging structure of the position between the stern structure of the diving instrument and a propeller, a stabilizer vane and a buoyancy block. The stern structure of the diving instrument includes the buoyancy blocks, the propellers and the stabilizer vanes and is characterized in that: the numbers of the buoyancy blocks, the propellers and the stabilizer vanes are all four and the four buoyancy blocks are respectively positioned in four quadrants and form a conical body and the bigger end of the conical body is connected with the stern end of the diving instrument. The four propellers are arranged with equal intervals in the shape of a cross along the circumferential direction of the conical body formed by four buoyancy blocks and are respectively located between the lateral sides of two adjacent buoyancy blocks. The four stabilizer vanes are arranged with equal intervals in the shape of an 'X' and are respectively located in the middle of the lateral sides of the four buoyancy blocks. By adopting the stern structure of the diving instrument, not only the occurrence of conditions of propellers being hurt by a mother-ship and the floaters being wound can be avoided and the work efficiency of the propellers can be improved, but also the maneuverability of the diving instrument can be improved.

Description

technical field [0001] The invention relates to a submersible. Specifically, it is the position arrangement structure between the stern of the submersible and the propeller, the stabilizer wing and the buoyancy block. Background technique [0002] It is known in the shipbuilding industry that the stern of a submersible is mainly composed of propellers, stabilizers, buoyancy blocks and other components. At present, the stabilizer wings on submersibles mainly have three arrangements: T-shaped arrangement, I-shaped arrangement and ten-shaped arrangement. For example, Russia's "Peace 1" and "Peace 2" 6,000-meter manned submersibles have T-shaped stabilizer wings. France's "Nautilus" 6000-meter manned submersible has an I-shaped arrangement of its stabilizers. Japan's "Deep Sea 6500" 6,500-meter manned submersible has a ten-shaped stabilizer wing. Whether it is a T-shaped stabilizer, an I-shaped stabilizer, or a submersible with a ten-shaped stabilized wing, their propellers ...

AI Technical Summary

Problems solved by technology

Since the propeller is behind the stabilizer wing, the propeller can only be installed at the end of the stern shaft of the submersible, so that the propeller protrudes out of the body line of the submersible, which is not only easy to be "bruised" by the mother ship, but also easy to be floated in the water Entwined

And because the propeller is behind the stabilizer, the propeller is in the flow field of the wake generated by the stabilizer, which affects the working efficiency of the propeller

In addition, since there is only one propeller, the submersible can only move forward and backward, but cannot move up and down and turn around, so the maneuverability is poor.
