Underwater diving propulsion device

Abstract

The invention discloses an underwater diving propulsion device. A mounting bracket of the device is arranged at the tail end of a casing, a fairing which is connected with the mounting bracket is located on the outer side of the casing, a battery pack is arranged in the casing, a direct current motor is arranged on the mounting bracket and located in the casing, the battery pack provides a power supply for the direct current motor, a rotating shaft of the direct current motor extends out of the mounting bracket to be connected with a magnet rotor, a segregation board is arranged on the inner wall of the fairing in a vertical and sealing manner, an interval is formed between the segregation board and the end surface of the magnet rotor, a rear bracket is arranged on the segregation board and located in the fairing, the two ends of an output shaft are respectively connected with a copper rotor and a propeller, the output shaft is arranged on the rear bracket through a bearing, an interval is formed between the end surface of the copper rotor and the segregation board, the end surface of the copper rotor corresponds to the end surface of the magnet rotor, a maneuvering handle extends into the casing to control the rotating speed of the direct current motor, and a measuring instrument is arranged at the end part of the maneuvering handle. The propulsion device overcomes the defects of a traditional propulsion device, the rotating shaft has favorable sealing performance, the safety and the reliable performance of the propulsion device are improved, the energy consumption is reduced, and the diving depth is increased.

Description

technical field [0001] The invention relates to an underwater diving propulsion device. Background technique [0002] The underwater diving propulsion device, also known as the underwater frogman booster, is one of the important aid equipment for navy frogmen or diving enthusiasts to dive. The underwater diving propeller provides people with a brand new way of diving. It improves the range and speed of people's activities in the water. It not only allows people to navigate freely on the water surface, but also can be used in industrial fields such as underwater search and rescue, underwater survey and Underwater diving propulsion in military fields such as frogman transportation and special operations. [0003] At present, all underwater submersible propellers use a direct connection between the motor and the propeller. Since the underwater submersible propeller works in an underwater environment, the sealing between its power and the propeller is a very critical technology...

AI Technical Summary

Problems solved by technology

[0003] At present, all underwater submersible propellers use a direct connection between the motor and the propeller. Since the underwater submersible propeller works in an underwater environment, the sealing between its power and the propeller is a very critical technology, which seriously affects the depth of diving. , which increases the energy consumption of the mechanical transmission of the propulsion device, reduces the use effect and life of the propulsion device, and brings certain hidden dangers to safety
