Title:
水域中の流れから動力を生成するための浮動性プラント
Document Type and Number:
Japanese Patent JP4309258
Kind Code:
B2
Abstract:
The present invention comprises a rotating member (400) designed for rotation actuated by currents in the body of water so as to function as energy supplier in a generator unit located in a body of water. The rotating member, as illustrated in Figure 7, is built up around a shaft (405) which is mounted (preferably at right angles) on a hub on the generator shaft. The rotating member according to one embodiment of the invention comprises an inner end piece (407) mounted on the shaft (405) at the attachment of the shaft to the hub, a tip (406) mounted at the outer end of the shaft, and a plurality of member sections (410) rotatably mounted on the shaft (405) between the end piece (407) and the tip (406). Each member section (410) is individually selectively pivotal and adjustable about said shaft, in order that the rotating member as such can assume the optimal pitch in relation to the water current.
