Submersible thruster

Abstract

The invention provides a submersible thruster, relating to wet type manned diving apparatus with cruising ability in 30m shallow water, which comprises a shell, a control handle, storage batteries sealed in the shell, a motor, a reducer, a transmission system, an electric control system, a propeller and a propeller flow guide cover, wherein, the shell is composed of a bow shell, a midship shell and a stern shell which are hermetically connected in sequence; the midship shell is hermetically connected with the stern shell by the transmission system arranged in a cavity of the stern shell; the transmission system comprises a coupling shaft and a coupling plate, wherein, the coupling shaft is used for connecting an output end of the reducer and an input end of the propeller and the coupling plate is fixedly arranged between the midship shell and the stern shell; the lower part of the coupling plate is hermetically connected with a hollow tail support; the coupling shaft penetrates into the tail support; the inner wall at the upper part of the tail support is provided with an axial stop ring and a stop copper sheathing which are used for limiting axial displacement of the coupling shaft; and the inner wall at the lower part of the tail support is provided with a lip-type sealing ring which is used for seal between the tail support and the coupling shaft.

Description

technical field [0001] The invention relates to a wet manned diving device with endurance in 30m shallow waters, in particular to a diving propeller. Background technique [0002] The submersible thruster is a tool that provides auxiliary propulsion power for underwater workers to improve their underwater movement speed and work efficiency. Foreign submersible thrusters started earlier, and were mainly used in industrial and military fields at the earliest. In the industrial aspect, it is mainly used in underwater survey, underwater search and rescue, and underwater maintenance, while in the military aspect, it is mainly used in special operations such as frogman transportation. Its notable feature is that it is fast, but it has a large volume and weight and is inconvenient to carry. Domestic research on underwater propulsion is still in its infancy, and relevant shipyards have organized similar research. Existing products not only have low propulsion speed and poor endura...

Problems solved by technology

Its notable feature is that it is fast, but its volume and weight are large and inconvenient to carry.

The development of domestic underwater propulsion is still in its infancy, and relevant shipyards have organized similar research. The existing products not only have low propulsion speed and poor endurance, but also generally have shortcomings such as poor sealing performance and reliability. Market Competitiveness
