CONSTITUTION:Plural blades 2 are fixed in parallel onto the underface of circular flat buoy 1 in the perpendicular direction against the advancing direction of wave. A shaft 4 is supported through a longitudinal bearing 3 in the buoy 1 at such position as will be proper center of gravity on the center line X-Y of buoy parallel with the blade 2 and a crank rod 5 fixed with a weight 6 is secured to the tip of said shaft 4. The shaft 4 is rotated through the crank rod 5 by the rolling of buoy 1. The rotation of said shaft 4 is increased through gears 7-12 to drive a generator 13.

Description

DETAILED DESCRIPTION OF THE INVENTION A power generation buoy that is an embodiment of the present invention will be described with reference to a plan sectional view in FIG. 1, a front sectional view in FIG. 2, and a side external view in FIG.

The buoy (1) has a flat circular shape, and several blades (2) are attached in parallel to the outside and lower side. The buoy is caused by the lateral movement of seawater caused by waves, so the blades are always perpendicular to the direction of wave travel, and the buoy is moved with the movement of the seawater, and the action of a weight inside the buoy prevents the buoy from being rotated. do. The center of the buoy is parallel to the slat inside the buoy @X-Y
At the top, a vertical bearing (3) is placed at a suitable center of gravity, which supports the shaft so that it can rotate freely.A lance ronde (5) is mounted on this vertical shaft as shown in Figure 22. A weight is attached to the end of the buoy, allowing it to freely rotate and reciprocate within the buoy in about half a rotation.There is a large gear (7) on the vertical shaft. Horizontal gears (8), (9),
(10), (11), and (12) to make the rotation high speed. Generator (13) Ic directly connected to rotate this at high speed.

This generator is an alternating current generator, and generates electricity perfectly normally in either left or right rotation.

Now, the state in which this buoy receives wave force will be explained with reference to Fig. 2. If the direction of wave travel is indicated by arrow (A), at the wave crest the seawater is moving in the wave travel direction CB), and at the wave trough the seawater is moving in the <a> direction. Therefore, the buoy's blade is subjected to the seawater reaction motion of arrow B (0).Now the wave is CD
) direction, the movement of seawater is (n), ('e
) and act on the slats alternately. Then, the seawater in the direction CD) hits the blade plate (1') with the force ζ (Gλ (T1) and (Iλ (J)). This pushing force is (Pλ (G input (H)
(1) (:J) Very strong. Therefore, the buoy is rotated in the direction of the arrow (K), and the blades try to be perpendicular to the direction (CD). Seawater from the opposite direction (E) also hits the buoy (
By turning it in the 'L) direction, it attempts to become perpendicular to the CD) direction. Maintaining the direction perpendicular to the traveling direction of the blade force ζ wave in this way allows the crank rod inside the buoy to always maintain the direction of the buoy in which the wave force is most effectively utilized.

Now, to explain the operation of the power generation mechanism, let us assume that the buoy is receiving waves from the (M) direction and is at the top of the wave. At this time, the buoy is pushed in the (B) direction by the movement of the seawater 〇 Therefore, the weight inside the buoy is moved by inertia in the (8) direction ζ Next, as the wave crest passes, the (Q) side of the buoy descends. Since the tilt causes a head difference between CI') and jD (Q), the weight increases the rotational force due to the weight and rotates the generator. Next, when the buoy is at the bottom of the wave, the seawater is moving in the opposite (0) direction, so the weight is moved by inertia in the (1) direction, and the spoon or the (Q) side hits the wave crest. It is pushed up (Q) and a drop is created in the horizontal direction (P), causing the weight to move in the (N) direction and generate electricity.In this way, the power of the waves causes the generator to rotate left and right and rotate at high speed. Since this is intermittent power from the power spreading current, by converting it to direct current using a rectifier and connecting it to the storage battery (15), stable power can be obtained as smooth direct current.

This power generation buoy has a simple structure and has good power generation efficiency because it converts energy from the sides, diagonals, and top and bottom of waves into electricity. Small power generating buoys are extremely useful for maritime beacons, lighthouses, radio buoys, etc., replacing conventional battery power sources as an unlimited power source, and large power generating buoys are extremely useful on the coast, at sea, on remote islands, etc., as they can serve as a power source superior to conventional power sources. This is a great invention.

In implementing the present invention, an alternating current generator is structurally advantageous, but a direct current generator may also be used. In this case, the polarity changes each time it is reversed. - Since this is a cyclic alternating current with the same wave period, the result is the same when rectified by a rectifier. In terms of structure, the buoy is free to include two or more power generating mechanisms within the buoy, and the shape of the buoy may be a deformed circle or a boat shape convenient for towing at sea.
