Problems solved by technology

[0006] However, the disadvantage of the known independently rotatable fluid power generators is that, due to the permanently repeated rotational movement, a continuous increase in the degree of twisting of the corresponding part, which is the connection to the fastening element and the resulting The above-mentioned parts themselves cannot be formed by rotating joints

Embodiment Construction

[0023]The basic components of a power plant 1 according to the invention are shown schematically and simplified in FIGS. 1 a and 1 b. A water turbine 2 is used to convert the kinetic energy of the water flow, which can be designed, for example, in the form of a propeller. The water turbine drives a generator 3 which is accommodated in a nacelle 9 or whose housing forms the nacelle. A pod body 4 is assigned to the pod 9 , which is used to distance the water turbine from the support body 5 . The support body 5 can be, for example, a pillar or a grating with anchors on the sea bottom 8 . Alternatively, a floatable unit can be provided as carrier body 5 , which is anchored by thick ropes and thus essentially fixed in position relative to the sea bottom 8 and free from relative rotation. A hinge connection device 6 is arranged between the pod body 4 and the carrier body 5. According to the present invention, the hinge connection device is constituted as follows, so that the activ...

Abstract

The invention relates to a rotatable generation unit for generating electric energy from a water flow, comprising: a water turbine; an electric generator, driven by the water turbine; a carrier body, wherein a first axis is provided; a nacelle body, with which a second axis, which is angled toward the first axis, is provided and which is moveable relative to the carrier body; a connecting cable, extending from the electric generator through the nacelle body to the carrier body; a hinge connection device between the carrier body and the nacelle body ,possessing a device which transmits a rotational movement of the nacelle body about the first axis into a rotational movement of the nacelle body about the second axis assigned therewith, so that the twisting of the connecting cable is limited.

Description

technical field [0001] The invention relates to a rotatable power plant for obtaining electrical energy from water currents, in particular from ocean currents or flowing water currents. Background technique [0002] Submerged power plants, which are designed independently of the embankment structure and are driven by the kinetic energy of water currents, in particular ocean currents, represent a great potential for exploiting renewable energy sources. Due to the high density of the flow medium, energy can already be harvested economically with relatively low flow velocities of approximately 2 to 2.5 m / s. This flow relationship can either be present as a tidal current or other ocean currents can be used which, in particular, can achieve economical velocities in straits. This flow can drive a hydroelectric power plant, which has a configuration similar to a wind power plant, that is to say uses a runner with rotor blades as a water turbine. However, other turbine concepts su...
