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

Abstract

Disclosed is a vertical axis ocean current power generation device provided with unfolding mechanisms and used for an underwater vehicle. Two vertical axis ocean current power generation devices are installed on a shell of the underwater vehicle, two crank driving rods are connected with two screw nuts through two screws respectively, and one parallelogram-shaped unfolding mechanism is formed by a blade, two cranks and an impeller shell. The blades rotate around the central axes under the impact of incoming flow, lift forces L and resistance forces D borne by the blades at different azimuth angles are different, tangential force driving rotation shafts to rotate is generated to enable the blades, a supporting mechanism and a power generation device support to rotate around the longitudinal axis of the underwater vehicle, winding stators are driven to rotate to cut permanent magnet rotors to generate induced electromotive force, and therefore kinetic energy of ocean currents is converted into electric energy used for the underwater vehicle. In the vertical axis ocean current power generation device provided with the unfolding mechanisms and used for the underwater vehicle, the power generated by capturing the energy of the ocean currents is in direct proportion to the spread length and the rotation radius of the blades, the problem of energy supply of the underwater vehicle is solved, the working time of the underwater vehicle is prolonged and cost is saved.

Description

technical field [0001] The invention relates to the field of underwater vehicles, in particular to an underwater vehicle vertical axis ocean current power generation device with a parallelogram unfolding mechanism. 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.
