Power supply device for the instrumentation of a fish farming plant, in which feeding takes place by means of a so-called central feeding plant. A blade wheel or a turbine, which is arranged to drive an electric generator, has a feed hose (1) arranged thereto and connected to the central feeding plant, liquid or air flowing and transporting feed in the feed hose, being lead or directed towards the blade wheel or turbine. The blade wheel comprises a rotor (4) with blades (5) which are made of a thread-like material or bristle in a way similar to a brush. The rotor (4) may be provided with magnets inducing electric voltage in a stationary coil (6) enclosed by the rotor (4). |
