Method for using submarine propeller thruster capable of deeply diving over kilometers at tail end of submarine main body of seat cabin

Abstract

The invention discloses a method for using a submarine propeller thruster capable of deeply diving over kilometers at the tail end of a submarine main body of a seat cabin. A connecting mechanism frame (X) arranged on the propeller thruster and a positioning plate (Q) arranged on the submarine main body of the seat cabin are two relatively independent and detachable structural parts. According to the electric propeller thruster, at least a rotor (2) or the rotor (2) and a stator (1) are surrounded by a metal fully-sealed isolation cavity (4) or (5) in a three-dimensional mode, and a rotating shaft (6) capable of vertically and downwards penetrating through a motor shaft seal (7) is arranged at the bottom of the metal fully-sealed isolation cavity; the metal sealing isolation cavity is filled with oil (S), and external high-pressure water is jacked to penetrate upwards to the interior of the motor through the motor shaft seal (7); all splicing gaps related to the metal sealing isolation cavity are connected through a non-detachable welding process; and the motor is arranged in a vertical state to horizontally drive the propeller (11) to operate.

Description

technical field [0001] The invention relates to a method in which a propeller propeller of a submarine capable of diving over a thousand meters is equipped at the tail end of a submarine main body of a cabin. Background technique [0002] Present submarine, its diving depth is limited, for example: be difficult to reach the depth of nearly 1,000 meters; Reason is many-sided, and wherein waterproof sealing measure is unsatisfactory one of reason of an extra large. ——People's conventional thinking is: use rubber or plastic-based flexible polymer materials to make sealing ring components and matching sealing structures to achieve conventional waterproof sealing measures. [0003] The maximum diving depth of submarine has always been a problem that people want to solve, otherwise, it will directly affect the exploitation of seabed combustible ice in the future (commercial exploitation is also a problem that has not been properly resolved in the world). ——Its reserves are twice ...

Problems solved by technology

[0005] ——The fatal flaw of the submersible pump as the prior art is just that: the diving depth is very shallow (generally no more than about 10 meters) and the maintenance work (not maintenance) that needs to be lifted out of the water regularly to remove seepage, and the deeper the diving, The shorter the period of the above "regular"
