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.

A nacelle for a wind turbine and a method for erecting a wind turbine are disclosed. The nacelle comprises a main unit arranged to be connected to a wind turbine tower, via a yawing arrangement, and at least one side unit mounted along a side of the main unit in such a manner that direct access is allowed between the main unit and the side unit(s), each side unit accommodating at least one wind turbine component, and at least one side unit being capable of carrying the wind turbine component(s) accommodated therein. The main unit and at least one of the side unit(s) are distributed side by side along a substantially horizontal direction which is substantially transverse to a rotational axis of a rotor of the wind turbine. A sufficient interior space of the nacelle is obtained while allowing the nacelle to be transported due to the modular construction. The weight of the wind turbine components is arranged close to the tower due to the transversal arrangement of the side unit(s) relative to the main unit.

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.

A wind turbine rotor blade extension fitting element, which extension fitting element is designed as a rotor blade rib with a recess and which can be pushed onto the rotor blade tip of a rotor blade to be extended, in such a way that the rotor blade tip protrudes through the recess and contacts the circumferential surface of the recess in an positive-locking manner. The extension fitting element has, on its outer circumference, an outer circumferential surface onto which a shell-like rotor blade extension can be pushed in an positive-locking manner. A core of the extension fitting element has slits and/or boreholes which, for stabilization, are filled with a material that has a higher strength and/or stiffness than the material of the core. In this way, the extension fitting element is strengthened for the transfer of high loads.

A wind turbine generator (10) includes a tower (12), a nacelle (14) rotatably mounted to the tower (12), the nacelle having a longitudinal axis and being configured to align the longitudinal axis with the direction of the incoming wind during operation of the wind turbine generator (10), one or more heat-generating components (22) housed in the wind turbine generator (10), and a containerized HVAC module (26) mounted on a roof (31) of the nacelle (14) and operably connected to the one or more heat-generating h components (22) for cooling the heat-generating components (22). The module (26) includes a shipping container (30) having a floor (32), a roof (34), a pair opposed longer side walls (36), a pair of opposed shorter end walls (38), and a longitudinal axis, the longitudinal axis of the shipping container (30) being oriented generally perpendicular to the longitudinal axis of the nacelle (14), the shipping container (30) having at least one heat exchanger (40) therein.
