Wave power generation device using wave receiving plate

Abstract

To provide a wave power generation system capable of extracting energy from moderate but frequent incoming waves and generating electricity.SOLUTION: The force of the incoming waves is received by a wave receiving plate (1), and the opening and closing motion thereby generated is transmitted through a steel wire (2) to a mainspring (3) and a one-way clutch (4), thereby rotating a shaft (5) to drive a generator (6) for power generation.SELECTED DRAWING: Figure 2

Description

[Technical Field]

[0001] The present invention relates to converting ocean wave energy into electricity. [Background technology]

[0002] Although various wave power generation devices have been proposed, no definitive device has yet been invented in terms of manufacturing cost and effectiveness.

[0003] This invention is a power generating device that combines a spiral spring (3) and a one-way clutch (4), which has never been seen before. It can generate electricity easily, does not require much production cost, and is easy to maintain if installed somewhere between large and small waves, so it has great potential to become widespread. Summary of the Invention [Problem to be solved by the invention]

[0004] It is necessary to create a device that can extract energy from frequent moderate waves. To do this, a spiral spring (3) and a one-way clutch (4) are combined so that when the wave-receiving plate (1) is tilted forward by the force of the waves, the downward movement of the steel wire (2) connected to the spiral spring (3) is smoothly transmitted to the shaft (5) of the generator via the one-way clutch (4). [Means for solving the problem]

[0005] The devices proposed so far are mainly propeller type and flowing water type that utilize the up and down motion of waves. This invention also utilizes the up and down motion of waves, but it attempts to generate electricity in a new way by using a spiral spring (3) and a one-way clutch (4). The installation site for this device should be selected not far from the coast and where moderate waves frequently occur. [Effects of the Invention]

[0006] The power spring (3) and one-way clutch (4) work together to generate electricity. [Brief explanation of the drawings]

[0007] [Figure 1] FIG. 1 is a cross-sectional view of a wave power generation device in which a spiral spring (3) and a one-way clutch (4) according to the present invention are combined.

[0008] [Figure 2] Figure 2 is a top view of the device of the present invention, with the shaft (5) connected to the generator (6) from the upper left.

[0009] [Figure 3] Figure 3 is a side view of the wave receiving plate (1) being pulled up and returned to its original position by the force of the spiral spring (3) as the waves pull out to sea. DETAILED DESCRIPTION OF THE INVENTION

[0010] In Figure 1, the shaft (5) is inserted into the shaft hole of the one-way clutch (4), and the spiral spring (3) is attached so as to embrace the one-way clutch (4). The rear end of the spiral spring (3) is fixed to an arbitrary point on the upper surface of the outer frame of the one-way clutch (4). The tip of the spiral spring (3) is connected to the steel wire (2), and the steel wire (2) is connected to the tip of the wave receiving plate (1).

[0011] In Figure (2), when waves surge in, the force of the waves pushes the wave receiving plate (1) forward, causing the steel wire (2) to be pulled by the wave receiving plate (1), and the spiral spring (3) connected to it is pulled out while rotating. At the same time, the one-way clutch (4) and shaft (5) also rotate together, starting the generator. At this time, the one-way clutch (4) is activated. Next, when the waves change to ebb, the waves on the wave receiving plate (1) disperse and the wave receiving plate (1) becomes lighter, so the force of the spiral spring (3) trying to return the wave receiving plate (1) to its original position easily. At this time, the one-way clutch (4) does not operate. [Explanation of symbols]

Claims

[Claim 1] The shaft (5) is inserted into the shaft hole of the one-way clutch (4), and the spiral spring (3) is installed so as to embrace the one-way clutch (4), and the rear end of the spiral spring (3) is fixed to any point on the outer circumferential surface of the one-way clutch (4), so that the spiral spring (3) and the one-way clutch (4) rotate together clockwise or counterclockwise. Furthermore, the tip of the spiral spring (3) is connected to a steel wire (2), and the steel wire (2) is connected to the tip of the wave receiving plate (1) to control the opening and closing of the wave receiving plate (1).
