The screw blade 5 is mounted on the tail end of a spindle-shaped screw body 7. When the screw blade 5 rotates in response to a tidal current, the central shaft 8 mounted in the screw body 7 is rotated.
The branch rod 6 is provided integrally with the abdomen of the screw body 7 so as to communicate therewith.

The screw blade 5 receiving the tide
In other words, the cylinder rod 9 rotates with respect to the support rod 1 so as to be in a posture facing this tide. That is, the cylindrical rod 9 rotates so that the spindle-shaped screw body 7 takes a posture along the flow of the tide, and the screw blade 5 mounted on the tail end faces the tide.

When the tidal current collides with the support rod 1, the flow is disturbed. Therefore, if the screw blade 5 is positioned downstream of the support rod 1, the rotation may not be smoothly achieved. Therefore, the screw body 7 on which the screw blade 5 is mounted is projected to the side of the support rod 1 via the branch rod 6 so that the turbulence of the tide does not adversely affect the rotation of the screw blade 5.

Now, there are many possible means for transmitting the rotational force of the central shaft 8 of the screw blade 5 rotating in response to the tidal current to the generator 3 installed in the station 2. This is achieved by the rotational force transmitting member 10 incorporated in the support rod 1 and the branch rod 6. Therefore, as described above, the screw body 7, the branch rod 6, the cylinder rod 9, and the support rod 1 communicate with each other while being sufficiently shielded at the respective connecting portions.

In the embodiment shown in FIG. 2, a chain 10a is used as the rotational force transmitting member 10. In the long support rod 1, the connecting gear 10 b is arranged in the middle, or the connecting gear 10 b is also provided in the direction changing portion such as between the branch rod 6 and the supporting rod 1.
Is arranged so that the rotational force can be smoothly transmitted to the generator 3 even when the cylinder rod 9 rotates or the screw body 7 swings. Since the chain 10a can cope with a slight bending or twisting, it is possible to reliably transmit the rotational force even when the above-mentioned rotation or swing occurs.

Further, in the embodiment shown in FIG.
The rotation shaft 10c is used as 0, and the ends of the rotation shaft 10c are connected by a bevel gear 10d. The bevel gear 10d is a portion in which the rotating shafts 10c are orthogonal to each other, particularly between the branch rod 6 and the support rod 1, and can cope with rotation and swing as in the case of the chain 10a.

By the way, the mounting position of the screw body 7 of each support rod 1 is at both the upper layer and the lower layer in the sea.
The screw blade 5 rotates in response to the tidal current in that portion. This is because, as described above, the flow direction of the tidal current differs between the upper part and the lower part of the sea, and the energy of the two tidal currents in the different flow directions can be effectively used by one device.
