Horizontal-axis ocean current power generation device for underwater vehicle

Abstract

The invention discloses a horizontal axis ocean current power generation device for an underwater vehicle. The power generation device is arranged in a groove of a revolving body of the underwater vehicle. The power generation device comprises an undercarriage unit, a yawing unit and a power generation unit. Rising and falling of the whole power generation device are achieved through the undercarriage unit. Through the yawing unit, the power generation unit can randomly rotate by 360 degrees in a horizontal plane so that active yawing can be performed along with a change of a ocean current direction to realize an incident flow function. The power generation unit drives an outer shaft and an inner shaft to rotate respectively through a front blade and a rear blade which rotate oppositely sothat an inner rotor and an outer rotor of a motor are driven to rotate oppositely, and magnetic induction lines are cut to generate power. The power generation device is high in controllability, highin conversion efficiency and compact in structure, and can be directly loaded on the underwater vehicle as an independent module. According to the device, ocean current kinetic energy is converted into electric energy used by the underwater vehicle, and an energy supply problem of the underwater vehicle is fundamentally solved.

Description

technical field [0001] The invention belongs to the field of ocean current power generation, and in particular relates to a horizontal axis ocean current power generation device for an underwater vehicle. Background technique [0002] In order to face the increasingly severe energy shortage problem, countries all over the world are turning their attention to the development of renewable energy. In the field of renewable energy, ocean current energy has the characteristics of regularity, high energy density and little impact from wind and waves, and has gradually become the focus of governments of various countries. my country's ocean current energy reserves are abundant, and its development and utilization potential is huge. If the ocean current in the environment where the vehicle is located can be collected and converted into electrical energy, then the underwater energy supply problem of the underwater vehicle will be solved and its underwater working time will be improv...
