Horizontal axis ocean current power generation device for underwater vehicles

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, in particular to a horizontal-axis ocean current power generation device for underwater vehicles. Background technique [0002] Underwater vehicle is a kind of underwater vehicle, including manned underwater vehicle and unmanned underwater vehicle, which can complete underwater exploration, detection and even military offensive and defensive tasks. Underwater vehicles have the advantages of large activity range, deep diving depth, access to complex structures, and no need for huge water surface support. They also have the characteristics of low cost and maintenance cost, reusability, convenient delivery and recovery, and long endurance. Now that ocean development is becoming more and more important, underwater vehicles have been paid more and more attention by various countries, and they play an important role in both civilian and military use. [0003] Energy plays a decisive role in the abil...

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
