  • Patent number: 9556848
    Abstract: This invention provides a tidal current generating device and an installation frame thereof. The tidal generating device includes an installation frame, at least three hydro turbines, and at least one power generation module. The installation frame of the tidal current generating device includes an outer frame and at least two buoy units. The at least two buoy units are disposed on two sides of the outer frame. When the installation frame of the tidal current generating device is used, the at least two buoy units are vertical to a horizontal plane and parallel to a direction of water flow. The at least three hydro turbines are disposed in parallel within the outer frame. The at least one power generation module is connected with the three hydro turbines. When water flows to the hydro turbines, the hydro turbines rotate to drive the power generation module to generate power.

  • Patent number: 9206573
    Abstract: The present invention provides a water flow regulating device and an ocean power generating device using the same. The water flow regulating device includes a main body, a water deflector, a rotating shaft, a winding shaft, a rope or cable, and a driving unit. The water deflector is pivotally connected with the main body. The rotating shaft is rotatably disposed at the main body. The winding shaft is disposed at the main body. One end of the rope or cable is fixed to the water deflector, and the other end bypasses the rotating shaft and the winding shaft, goes back to the water deflector and is fixed to the water deflector. The driving unit is connected with the rotating shaft to drive the rotating shaft to rotate, such that the rope or cable is driven to withdraw or release to control the water deflector to rotate.
