Wave energy conversion device

A wave energy conversion device, comprising:

• a housing having an inlet chamber and an outlet chamber, the inlet chamber having a first opening, and the outlet chamber having a second opening, each of the first and second openings being configured to face a front of the housing;
• a pair of one-way flow guiding grates disposed at a front side of the housing;
• a hydropower turbine disposed within the housing;
• and
• a first one-way flow guiding grate disposed on the first opening, and a second one-way flow guiding grate disposed on the second opening,
• wherein the first and second openings are oriented to form an angle ranging from greater than or equal to 30 degrees to 180 degrees, forming a transverse V-shape in a longitudinal cross-section of the housing,
• wherein the first one-way flow guiding grate is configured to only allow water to enter the inlet chamber, and the second one-way flow guiding grate is configured to only allow water to exit the outlet chamber,
• wherein from an intake/discharge port toward a rear wall of the housing, a flow passage becomes smaller,
• wherein the inlet chamber and outlet chamber are in fluid communication with each other through a water channel, wherein the hydropower turbine is disposed within the water channel,
• wherein the hydropower turbine is connected to a rotary electricity generator disposed above the housing through a shaft, and
• wherein the inlet chamber and outlet chamber are disposed within the housing asymmetrically, and
• wherein the inlet chamber is in fluid communication with outside through a first air vent disposed on top of the housing, and the outlet chamber is in fluid communication with outside through a second air vent disposed on top of the housing.
