付けられたダリウス水車５を取付けたものである。(Prior Art) Conventionally, there is a technology disclosed in Japanese Unexamined Patent Publication No. 58-72677 as a tidal current power generation device using the Darrieus type water turbine as described above. A float frame 2 is provided above the float 1 which is floating on the water surface or semi-submerged below the water surface, a power generation 113 is installed on this, and is connected to the rotating shaft 3a of the generator 3. A Darius water wheel 5 is attached to a rotating shaft 4 which extends downward from the rotating shaft 2 and is submerged in water, and a Darius water wheel 5 has a darius blade 5a attached in parallel to the rotating shaft 4.
そして、この発電装置にあっては、潮流の特徴である潮

得られるという特徴を有していた。This power generation device responds to changes in the direction of tidal currents, which is a characteristic of tidal currents.In other words, the direction of rotation remains constant regardless of the direction of tidal flow, and power can be obtained relatively efficiently. It had the following characteristics.

あった。By the way, in the power generating apparatus described above, although the Darius turbine 5 is rotated regardless of the direction of the tidal current as described above, there is a problem in that it is affected by the flow velocity of the tidal current. That is, as shown in Fig. 5, since the power generation device is connected by the chain 7 to the anchor weight sunk on the seabed, when the flow speed of the tidal current increases, the metal body is tilted, and therefore, the Darius blade 5a is connected to the anchor weight sunk in the seabed by the chain 7. Is it no longer perpendicular to the direction? . Therefore, there was a problem in that the rotational speed of the Darius turbine 5 decreased, resulting in a decrease in power generation efficiency.

向上を図ったものである。The tidal current power generation system using the Darius-type water m- is equipped with a rudder on the float so that the float always faces in the same direction with respect to the direction of the tidal current. At the same time, by forming the Darius turbine horizontally to the water surface, even if the float court is tilted due to the tide or current, the surface of the Darius turbine facing the tidal current remains constant, and the rotational speed is not affected at all. This is intended to improve power generation efficiency.

る。As described above, the present invention provides a Darrieus type water turbine which is attached to the float so that the float is always oriented in a constant direction with respect to the III flow and the axis of rotation is parallel to the water surface by the rudder attached to the float. Since the Darrieus blades are oriented in a direction perpendicular to the tidal flow, the Darrieus turbine is rotated at a rotational speed proportional to the speed of the tidal flow, so that the Darrieus turbine is always rotated in an optimal state regardless of the direction of the tidal flow. This has the effect that electric power proportional to the speed of the power flow can be obtained, and a highly efficient power generation device can be obtained.
