Ocean wave power generation device using spring and clutch

Abstract

To provide ocean wave power generation by taking out energy of medium-sized waves that come in busily and transmitting it to a generator.SOLUTION: Energy at the time of descent of vertical motion of a semi-submerged floating body (5) is transmitted to a spiral spring (3) to rotate a one-way clutch (2) integrated with the spiral spring (3). A shaft (1) connected the clutch is rotated, a generator (6) connected to the shaft is rotated, and power is generated.SELECTED DRAWING: Figure 1

Description

Technical Field

[0001] The present invention relates to converting the energy of waves into electricity.

Background Art

[0002] Although various wave power generation devices have been proposed, none have been invented that are decisive in terms of manufacturing cost and effectiveness.

[0003] The present invention is a power generation device that combines a hitherto unprecedented spring (4) and a one-way clutch (2), enabling easy power generation with relatively low manufacturing costs, and thus has the potential to become widespread. It is also suitable for installation in a place where maintenance is easy, targeting waves of medium height, such as those between large and small waves.

Summary of the Invention

Problems to be Solved by the Invention

[0004] There is a need to create a device that extracts energy from frequently occurring medium-sized waves. For this, a spring (4) and a one-way clutch (2) are combined so that the downward movement of the spring (4) is smoothly transmitted to the shaft of the generator via the one-way clutch (2).

Means for Solving the Problems

[0005] The devices proposed so far are mainly of the propeller type and the water flow type that utilize the vertical movement of waves. Similarly, the present invention also utilizes the vertical movement of waves, but attempts to generate electricity by a new method that combines a spring (3) and a one-way clutch (2). The installation location of this device should be selected in a place not too far from the coast where medium-sized waves frequently occur.

Effects of the Invention

[0006] The spring (3) and the one-way clutch (2) mesh well to enhance the power generation effect.

Embodiments for Carrying Out the Invention

[0010] In Figure 1, the spiral spring (3) is attached so as to embrace the one-way clutch (2) into which the shaft (1) is inserted. The rear end of the spiral spring (3) is fixed to an arbitrary point on the upper surface of the one-way clutch (2), and the tip of the spiral spring (3) is connected to the top of the semi-submersible floating body (5).

[0011] When the semi-submersible floating body (5) descends, the spiral spring (3) and the one-way clutch (2) rotate counterclockwise as a unit. At the same time, the clutch engages, and the shaft (1) also rotates counterclockwise in synchronization.

[0012] When the semi-submersible floating body (5) ascends, the spiral spring (3) and the one-way clutch (2) rotate clockwise as a unit, but since the clutch does not engage, it has no effect on the shaft (1).

[0013] [Figure 3] Figure 3 is a side view of a plurality of the devices of the present invention connected to the shaft (1).
