TIDAL CURRENT POWER PLANT

摘要

PURPOSE: A tidal current power plant is provided to enable a tidal current generator to float by injecting air into the case via a main buoy so that divers are unnecessary in repair and maintenance process. CONSTITUTION: A tidal current power plant comprises a tidal current generator(10), a case(20), an air injection pipe(50), and a support unit(30). The tidal current generator is installed under water. The case has an air chamber inside and supports the tidal current generator. The air injection pipe connects to the air chamber and is extended to the outside of the case to inject the air thereinto from the outside. The support unit is coupled with the case. An opening(21) is formed in the case so that seawater inside the air chamber can flows out to the outside.
