Flow-induced vibration combination power generation device

Abstract

The invention provides a flow-induced vibration combination power generation device which comprises multiple ocean current energy combination power generation units uniformly distributed on the outerside wall of a center pillar fixed to a pile foundation in the circumferential direction. Each ocean current energy combination power generation unit sequentially comprises an upper-layer connecting rod, a middle-layer connecting plate and a lower-layer connecting plate fixedly connected with the center pillar from top to bottom; a fan-shaped ocean current energy power generation unit is arrangedbetween each upper-layer connecting rod and each middle-layer connecting plate; and a vortex-induced vibration energy replenishment and acquisition device is arranged between each middle-layer connecting plate and each lower-layer connecting plate. The flow-induced vibration combination power generation device provided by the invention is formed by a fan-shaped ocean current energy power generation mode and the vortex-induced vibration energy replenishment and acquisition devices, and is used for generating power by utilizing ocean current energy. Compared with a traditional fan blade type power generation mode, the turbofan type ocean current energy power generation mode is small in resistance and high in utilization rate; and the vortex-induced vibration energy replenishment and acquisition devices utilize the vibration of ocean current vortex shedding for driving a piezoelectric plate to generate power, so that relatively speaking, the flow-induced vibration combination power generation device is direct in energy source, low in cost and simple in structure.

Description

technical field [0001] The invention belongs to the field of marine resource utilization, in particular to a flow-induced vibration combined power generation device. Background technique [0002] With the continuous development of the economy, the development of onshore energy has been unable to meet human needs for energy. In the ocean, which accounts for 71% of the earth's surface, there is a large amount of new energy. The development and utilization of marine new energy has received more and more attention from the international community. This includes ocean current energy. Turbofans have been basically used in ocean current energy for energy utilization. The form is too single, the utilization rate is low, and the conversion is unstable. Therefore, how to change the utilization method and improve the utilization rate and stability has become an increasingly important issue in recent years. topics of concern.
