Oscillating water column type wave power generation device with adjustable air chamber inlet height

Abstract

The invention discloses an oscillating water column type wave power generation device with adjustable air chamber inlet height. The oscillating water column type wave power generation device has the advantages that the problem that in the prior art, an oscillating water column type wave power generation device is fixed in structure and cannot deal with the environment change in real time can be solved, the air chamber inlet height is adjusted in real time, the volume of an air chamber is changed, the changes of the water depth, the incident wave period and the wave height can be dealt with, and therefore the optimal wave energy conversion efficiency of the power generation device can be guaranteed. According to the technical scheme, the oscillating water column type wave power generation device comprises the air chamber, a front wall is fixed to the front side of the air chamber, a baffle connected to the front wall in a sliding mode is arranged in the front wall, the air chamber inletheight is changed by adjusting the height of the baffle in real time, a ballast water tank is arranged at the bottom of the baffle and is connected to a two-way water pump through a water pipe, and the two-way water pump introduces or pumps seawater into the ballast water tank so as to overcome the influence of the external force on lifting of the baffle.

Description

technical field [0001] The invention relates to a wave power generating device, in particular to an oscillating water column type wave power generating device with an adjustable inlet height of an air chamber. Background technique [0002] The oscillating water column type wave power generation device is a kind of wave power generation device that is widely used at present. The wave energy capture capability of the oscillating water column wave power plant is related to many factors, such as: the water depth at the power plant, the incident wave period, the wave height, and the volume of the gas chamber. [0003] However, the structure and size of the currently used oscillating water column wave power generation device are fixed, especially the height of the inlet of the air chamber cannot be adjusted in real time, which makes it impossible to cope with changes in water depth and incident waves due to tides, weather factors, etc. Period and wave height changes, so it is imp...
