Abstract

The invention aims to provide a swing type hydrofoil tidal current energy-powered electricity generating set. The electricity generating set comprises three sets of crank-rocker mechanisms, wing panels, synchronous belts, belt wheels, a rotating shaft, a torque meter, a gearbox, a flywheel and a generator. By a luffing four-rod mechanism, transformation from up-and-down oscillation of a hydrofoil to unidirectional rotation of the rotating shaft can be effectively realized in order to drive another set of swinging four-rod mechanism; the rotation of a crank is transformed into up-and-down oscillation of a swinging rod so as to effectively control the law of motion of oscillating angles of the wing panels; the rotating speed of the rotating shaft is accelerated by the gearbox, and finally energy is transmitted to the generate to realize energy utilization. By ingeniously utilizing the own mechanical properties of the four-rod mechanism, the electricity generating set disclosed by the invention realizes an automatic energy collection process of the device, prevents energy loss caused by complex structure of an energy collecting device, control by a motor and the like, and has a quite large development range in future tide current energy collection.

Description

technical field [0001] The present invention relates to a power generation device, in particular to a tidal current power generation device. Background technique [0002] With the excessive consumption of fossil fuels such as oil and coal, the development and utilization of renewable energy such as tidal energy, wind energy, solar energy, etc. has attracted more and more attention from all over the world. As an important form of ocean energy, tidal energy has the advantages of high energy density, less environmental pollution, regular changes and good predictability compared with solar energy and wind energy. It is also known as one of the world's top ten clean energy sources in the future. At present, most of the utilization forms of tidal current energy are turbines with rotating blades and corresponding generators for energy capture. However, this method of tidal current energy capture has encountered some accusations, such as: large area, fast tidal current speed, and no...
