The invention discloses an oscillating water column type wave power generation device with an adjustable air chamber inlet height, which solves the problem that the structure of the oscillating water column type wave power generation device in the prior art is fixed and cannot respond to environmental changes in real time. The entrance height changes the volume of the air chamber to cope with changes in water depth, incident wave period, and wave height, so as to ensure the optimal wave energy conversion efficiency of the power generation device; the technical solution is: include the air chamber, and the front side of the air chamber is fixed with a front wall , the inside of the front wall has a baffle slidingly connected with it, and the height of the air chamber inlet can be changed by adjusting the height of the baffle in real time; the bottom of the baffle is provided with a ballast water tank, and the ballast water tank is connected to a two-way water pump through a water pipe, and the two-way The water pump introduces seawater into or pumps out the ballast water tank to overcome the influence of external force on the 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...
