underwater diving propulsion

Abstract

The invention discloses an underwater diving propulsion device, that is, the installation bracket of the device is arranged at the tail end of the casing, the guide cover is connected with the installation bracket and is located outside the casing, the battery pack is arranged in the casing, and the DC motor is arranged on the installation bracket And located in the casing, the battery pack provides DC motor power, the DC motor shaft extends out of the mounting bracket and connects to the magnetic rotor, the isolation plate is vertically sealed on the inner wall of the shroud and separated from the end face of the magnetic rotor, the rear bracket is located on the isolation plate and is located on the guide In the flow cover, the two ends of the output shaft are respectively connected to the copper rotor and the propeller. The output shaft is installed on the rear bracket through the bearing. The end face of the copper rotor is spaced from the isolation plate and corresponds to the end face of the magnetic rotor. The control handle extends into the housing and controls the speed of the DC motor. , The detection instrument is located at the end of the joystick. The propulsion device overcomes the defects of the traditional propulsion device, has good sealing performance of the rotating shaft, improves the safety and reliability of the propulsion device, reduces energy consumption, and increases the diving depth.

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...

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
