Swing wing type ocean current energy power generating device

Abstract

The invention discloses a swing wing type ocean current energy power generating device. The swing wing type ocean current energy power generating device comprises a supporting frame, a motion mechanism is connected to the supporting frame and connected with an energy extracting mechanism, the energy extracting mechanism comprises a crank and rocker mechanism which transmits energy extracted from the motion mechanism to an energy conversion mechanism, and the energy conversion mechanism comprises a power generator; and the motion mechanism is connected with an attack angle adjusting mechanism, and the attack angle adjusting mechanism adjusts and controls an attack angle degree of the motion mechanism so as to enable the motion mechanism to achieve preset pitching motion. The hydrofoil attack angle adjusting mechanism is arranged, so that the problem in control over the hydrofoil attack angle degree is solved; and as the hydrofoil pitching motion is accurately controlled by monitoring the position of a swing rod, the swing wing type ocean current energy power generating device can adapt to different water flow speeds, kinetic energy of the water flow is sufficiently captured, and the power generation efficiency and power are improved. A transmission system composed of a four-link mechanism and a synchronization belt in a transmission manner is used, so that the structure is simple, mechanical losses are small, and the conversion efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of new energy power generation, and in particular relates to a swing-wing type ocean current power generation device. Background technique [0002] In shallow seas, straits, bays or estuaries, high tides and low tides will cause strong currents and high water flow speeds, and the kinetic energy of the tides can be directly used to drive hydro turbines to generate electricity. The method is similar to wind power generators, called tidal current generators , has a good prospect for development and utilization. Compared with wind energy and solar energy, its energy density is large and easy to predict, so it is more convenient to use. Countries around the world pay more and more attention to the development and utilization of tidal current energy, and various tidal current energy generation technologies have made continuous breakthroughs. Among them, European and American countries are more advanced, but there ...
