AIR TURBINE AND POWER GENERATION DEVICE

WIPO Patent Application WO/2021/129657

A1

Disclosed are an air turbine and a power generation device. The air turbine comprises an air chamber (2), an air valve (3) and a rotor (4). The air chamber comprises a first opening (21) in communication with the atmosphere; air pressure in the air chamber is adjustable, and the difference between the air pressure in the air chamber and the atmospheric pressure comprises a first air pressure difference and a second air pressure difference; the air valve is connected to the air chamber, and is configured to open under the action of the first air pressure difference such that the air chamber is in communication with the atmosphere by means of the air valve and the first opening so as to form a first airflow, and is closed under the action of the second air pressure difference such that the air chamber is in communication with the atmosphere by means of the first opening so as to form a second airflow, with the direction of the first air pressure difference being opposite to the direction of the second air pressure difference; and the rotor is configured to be driven by the second airflow to rotate. The air turbine can be used to convert kinetic energy of the rotor into electric energy, for example, use wave fluctuations to obtain the first air pressure difference and the second air pressure difference and finally convert wave energy into electric energy.
