Maintenance-free electric propeller structure of submarine capable of realizing deep diving over 1000 meters and using oil for waterproof sealing

Abstract

A maintenance-free electric propeller structure of a submarine capable of realizing deep diving over 1000 meters and using oil for waterproof sealing is characterized in that at least a rotor (2) or the rotor (2) and a stator (1) are encircled by a narrow type metal sealing isolation shield (4) or a wide type metal sealing isolation shield (5) in a three-dimensional way, and a spindle (6) capableof downwards passing through a motor shaft seal (7) is arranged the bottom of the metal sealing isolation shield; the metal sealing isolation shield is filled with oil (S), for performing jacking thepermeation upwards to the inside through the motor shaft seal (7) by an external high-pressure water body; all splicing gaps of the metal sealing isolation shield are connected by a non-detachable welding process; and a motor is arranged in a vertical state. A submarine electric propeller comprising a propeller (11) is fitted to the tail end of the submarine main part as a cabin, and the connection between the submarine electric propeller and the submarine main part is detachable.

Description

technical field [0001] The invention relates to a structure of an electric propeller propeller for a submarine capable of diving over a thousand meters in depth and free from maintenance to allow oil to be waterproof and sealed. 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...

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"
