1. 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.
