Horizontal axis ocean current power generation device for underwater vehicle

Abstract

Disclosed is a horizontal axis ocean current power generation device for an underwater vehicle. The horizontal axis ocean current power generation device is symmetrically and fixedly arranged between a front aircraft segment and a middle aircraft segment. Three unfolding mechanisms are evenly distributed and arranged in grooves in the circumference of an impeller shell of a mounting support, and blades at the top ends of the three unfolding mechanisms stretch out of the impeller shell. The unfolding mechanisms are arranged in the grooves in the circumferential surface of the impeller shell; a winding stator of an electric generator is fixedly arranged on a central shaft; the blades are affected by ocean current torque; and the blades, the mounting support and a permanent magnet rotor of the electric generator rotate jointly around the longitudinal axis of the underwater vehicle, and therefore the permanent magnet rotor of the electric generator does the relative motion relative to the winding stator. A magnetic induction line is cut so as to generate induced electromotive force, and therefore kinetic energy of the ocean current is converted into mechanical energy, and then the mechanical energy is converted into electric energy which is supplied to the underwater vehicle to be used. The working time of the underwater vehicle is prolonged, and the cost is saved.

Description

technical field [0001] The invention belongs to the field of underwater vehicles, and in particular relates to a horizontal-axis ocean current power generation device for underwater vehicles. Background technique [0002] An underwater vehicle is a vehicle that sails underwater, including manned underwater vehicles and unmanned underwater vehicles, which can complete underwater exploration, detection, and even military offensive and defensive tasks. Underwater vehicles have the advantages of large range of activities, deep diving depth, access to complex structures, and no need for huge surface support. They also have the characteristics of low cost and maintenance costs, reusability, convenient launch and recovery, and long battery life. Now that ocean development is becoming more and more important, underwater vehicles are getting more and more attention from various countries, and they play an important role in both civilian and military use. [0003] Energy plays a deci...

AI Technical Summary

Problems solved by technology

The device collects the sloshing energy of the aircraft through the inertial pendulum swing and the movement of the mass block caused by ocean disturbances, but the sloshing energy power generation device is placed inside the aircraft and does not directly contact the ocean, so its conversion efficiency is low
