Abstract
Official abstract text for this publication.
An underwater flow turbine includes a gondola having an interior, a generator in the gondola interior, a rotatable hub connected to the gondola and configured to support a plurality of rotor blades, the rotatable hub being operatively connected to the generator, and an air handling device, such as a fan or an air filtration system, in the gondola and/or in the hub.
First claim
Opening claim text (preview).
What is claimed is: 1 . An underwater flow turbine comprising: a gondola having an interior, a generator in the gondola interior, a rotatable hub connected to the gondola and configured to support a plurality of rotor blades, the rotatable hub being operatively connected to the generator, and an air handling device in the gondola and/or in the hub. 2 . The flow turbine according to claim 1 , wherein the air handling device includes an inlet via which a gaseous medium enters the air handling device and an outlet through which the gaseous medium leaves the air handling device. 3 . The flow turbine according to claim 1 , including an access hatch in the gondola and/or in the hub, and a conduit extending from the outlet of the air handling device to the access hatch. 4 . The flow turbine according to claim 3 , wherein the air handling device comprises a fan configured to force a gaseous medium through the conduit. 5 . The flow turbine according to claim 1 , wherein the air handling device includes a fan configured to move a gaseous medium through the air handling device. 6 . The flow turbine according to claim 1 , wherein the air handling device includes an air filtration device. 7 . The flow turbine according to claim 6 , wherein the air filtration device includes a chemical air filter and/or a mechanical filter. 8 . The flow turbine according to claim 2 , including: an access hatch in the gondola and/or in the hub, wherein the outlet of the air handling device is arranged adjacent to the access hatch. 9 . The flow turbine according to claim 1 , including a sensor configured to determine at least one condition of a gaseous medium present in the gondola and/or the hub. 10 . The flow turbine according to claim 9 , wherein the sensor is configured to analyze a composition of the gaseous medium. 11 . The flow turbine according to claim 9 , wherein the sensor includes a transceiver configured to transmit a signal indicative of the determined condition and receive a control signal configured to activate and/or deactivate the sensor. 12 . The flow turbine according to claim 1 , including: a sensor configured to determine at least one condition of a gaseous medium present in the gondola and/or the hub, and a control unit configured to activate and/or deactivate the air handling device in response to a control signal. 13 . The flow turbine according to claim 12 , wherein the control signal originates outside the gondola and the hub. 14 . The flow turbine according to claim 9 , including a control unit configured to activate and/or deactivate the air handling device based on an output of the sensor. 15 . The flow turbine according to claim 14 , wherein the control unit is configured to evaluate information received from the sensor and to activate and/or deactivate the air handling device when information indicates that the condition is above or below a predetermined value.
