  • Patent number: 10190566
    Abstract: This invention provides a modularized ocean energy generating device and a built-in module thereof. The built-in module includes an inner frame, at least one hydraulic generator module, at least one mounting shaft, at least one driving unit, and at least two barriers. The modularized ocean energy generating device includes an outer frame, and the inner frame is detachably disposed in the outer frame. The hydraulic generator module is disposed in the inner frame and is mounted at the at least one mounting shaft, and the at least one mounting shaft is rotatably mounted at the inner frame. The driving unit is connected to the mounting shaft to drive the mounting shaft to rotate. The barriers are disposed at the inner frame or the outer frame and located at upstream and downstream sides of the hydraulic generator module along a water flow direction, respectively.

  • Patent number: 10054103
    Abstract: A rolling-door-type load regulating device and an ocean energy power generating device using the same are described herein. The rolling-door-type load regulating device includes a water guiding unit, a roller spindle, and a driver. The water guiding unit includes at least two water guiding plates connected in parallel. The roller spindle is fixed to one end of the water guiding unit. The driver is connected with the roller spindle and drives the roller spindle to rotate to spread or retract the water guiding unit. The rolling-door-type load regulating device in the invention can regulate the load suffered by the hydraulic turbine. Therefore, the power generated by the ocean energy power generating device can be stably output and be directly used, thereby solving the problem that the output power of the conventional ocean energy power generator has wide fluctuations and poor stability.

  • Patent number: 9765752
    Abstract: This invention provides a modularized ocean energy generating device including an outer frame, at least four inner frames, and at least four hydraulic generator modules. The at least four inner frames are detachably disposed in the outer frame. The at least four hydraulic generator modules are disposed in the at least four inner frames, respectively. The modularized ocean energy generating device in the invention includes at least four built-in modules, and the hydraulic generator modules can be distributed in an array. By the detachable inner frames and the outer frame, modularized assembly and installation can be realized, thereby greatly reducing preserving and installing costs.
