## Abstract

This invention is a wave powered electricity-generating mechanism which utilizes the fluctuations of multiple pontoons and ratchets' direction control to integrate various gear speeds into a high speed in order to drive an electricity generator. There are low, medium, and high speed gear sets. Low speed is for a quick start, higher speeds are to adopt lower speeds. The highest speed can be calculated in advance by adjusting the number of dynamic units, gear ratios, and number of transmission phases of gear sets in order to keep a designated output speed. This mechanism does not need to be fastened to the coast. Due to the independence feature of each dynamic unit, the number of dynamic units can be adjusted to meet various power output requirements.

## Claims

### Claim 1

A wave-powered electricity generator, comprising a basic frame being equipped with at least two sets of dynamic unit that is carrying two pontoons driven up and down by wave power to drive a power axis in a single direction; a backbone frame being connected to the basic frame and comprising an electricity-generating gear sets which are connected to the corresponding power axis in the basic frame, wherein the electricity-generating gear sets consolidate spinning powers to drive an electricity generator to generate electricity.

### Claim 2 (depends on 1)

The generator as claimed in claim 1, wherein the two pontoons are connected to the two ends of a connection rod which carries two power ratchets spinning in opposite directions due to ratchet regulation, wherein one of these two power ratchets is connected to two coaxial indirect gears so that the spin of the power ratchet is direction-reversed, consequently, these two power ratchets' dynamic is transmitted to the power axis in the same direction.

### Claim 3 (depends on 1)

The generator as claimed in claim 1, wherein the dynamic units are duplicated in number, and has an active gear and a dynamic axis which are one to one correspondent, wherein each active gear connects to the corresponding electricity-generating gear set for consolidating a spinning force into low, medium, or high speed spin which is depending on the gear-ratio combination, to drive an output axis and finally to drive an electricity generator to generate electricity.

### Claim 4 (depends on 3)

The generator as claimed in claim 3, wherein each electricity-generating gear set which is consisted of a passive gears corresponding to one active gear, and the output axis is equipped with output gears which are connected to the passive gears of the electricity-generating gear sets.

### Claim 5 (depends on 1)

The generator as claimed in claim 1, wherein the power axis connects to the electricity-generating gear set with a chain or a transmitting gear set for driving force transmission.

### Claim 6 (depends on 5)

The generator as claimed in claim 5, wherein the transmitting gear set comprises multiple transmitting gears, and the number and size of the transmitting gears are adjusted to the specification and the spinning direction of the active gear.

### Claim 7 (depends on 5)

The generator as claimed in claim 5, wherein the height of the backbone frame is adjustable for avoiding a direct contact between the electricity-generating gear sets of the backbone frame, and the power gears and the power axis of the basic frame.

### Claim 8 (depends on 5)

The generator as claimed in claim 5, further comprises a derailleur, and further has at least two active gears on every connecting axis, the active gears are in different sizes and arranged in incremental or decremental order, the derailleur is used to pull the chain and let the power axis connect to a certain sized active gear, so that the speed of output axis can be properly adjusted.

### Claim 9 (depends on 8)

The generator as claimed in claim 8, further comprises a constant speed control device which comprises a control unit, a brake and a speed sensor. When the control unit acknowledges the speed of the output axis has exceeded a designated speed, it will activate the brake to reduce the speed of the output axis until the speed slows down to the designated speed and then the brake is released.

### Claim 10 (depends on 9)

The generator as claimed in claim 9, the control unit of the constant speed control device also connects to the derailleur, the derailleur may be manually or automatically operated, and the speed of the output axis can be adjusted.
