Abstract: The wind-power generation device contains a generator a power member having a gear box and a transmission box. The gear box contains a fan, a passive gear set, a transmission gear set, a supporting axle, and an output axle. The fan contains fan blades on an active axle with an active gear engaging the passive gear set. The passive gear set contains a first passive gear and a second passive gear. The transmission gear set contains a first transmission gear and a second transmission gear engaging each other. The first passive and transmission gears are mounted on the output axle with an output gear. The second passive gear and the second transmission gear are mounted on the supporting axle. The transmission box contains a transmission axle engaging the generator. A transmission gear on the transmission axle inside the transmission box is engaged by the output gear.

Abstract: A tidal power generation device includes at least a chassis, a rail frame, and a chain support rack. A driver is provided at an end of the rail frame. The driver includes a connection bar. The chain support rack is set on the chassis and includes toothed wheels that support and operatively couple a chain that is coupled to the connection bar. One of the toothed wheels has a shaft that is supported by a one-way bearing and is operatively coupled to a first transmission axle by mated gears. The first transmission axle drives a second transmission axle, which is coupled to a dynamo. The driver is caused to move frontward by sea waves for driving the first transmission axle through the chain and the toothed wheels, so as to cause the rotation of the second transmission axle for transmitting torque to the dynamo to generate electricity.
