Description

DUAL-LINK OSCILLATING APPARATUS AND ITS ACTIVATING METHOD BACKGROUND OF THE INVENTION 1. Field of the Invention < RTI ID = 0.0 >

The present invention relates to a dual interlocking rotary device, a method of stopping the same, and a method of operating the same, and more particularly, An interlocking reciprocating rotary device, a stopping method and an operation method thereof.

Recently, with the depletion of fossil resources, which are the main energy sources of mankind, global warming due to the rapid increase of greenhouse gas emissions has accelerated, and there is a growing interest in environmentally friendly renewable energy around the world.

There are tidal, algae, ocean current, blue, offshore wind, and water temperature, which are pollution-free energy sources that can be used in the ocean. One of the marine energy sources available on the coast of the south sea of Korea is tidal current.

Unlike tidal power generation, which uses even the potential energy of seawater, tidal power generation is more eco-friendly in that it does not require large-scale construction because it generates electricity by turning the aquifer through the flow of seawater. In addition, since algae can be predicted differently from wind power and the density of seawater is about 800 ~ 1000 times higher than air, there is an advantage that even a relatively small aberration can produce more energy than wind power.

US-A-2013-0202407 discloses OSCILLATING HYDROFOIL, TURBINE, PROPULSIVE SYSTEM AND METHOD FOR TRANSMITTING ENERGY, and US Patent Publication No. 2013-0202407 discloses a hydraulic-based power transmission device that includes a vertical post And a first hydrofoil and a second hydrofoil extending in the transverse direction in the post and rotating by the flow of the fluid and moving along the longitudinal direction of the post.

More specifically, the hydraulic power transmission device of U.S. Patent Application Publication No. 2013-0202407 is provided with a first hydraulic cylinder provided inside the post and operating as the first hydrofoil reciprocates, and a second hydraulic cylinder provided inside the post And a second hydraulic cylinder provided in the second hydrofoil and operated according to the reciprocating motion of the second hydrofoil. The first hydraulic cylinder and the second hydraulic cylinder produce kinetic energy by converting the kinetic energy generated by the movement of the inner fluid into mechanical one as the first hydrofoil and the second hydrofoil linearly reciprocate.

However, the hydraulic power transmission of U.S. Patent Publication No. 2013-0202407 has a drawback in that the pitch control of the foil must be continuously performed throughout the operation. Since the energy used to control the pitch of the foil acts as a factor for lowering the generation amount of the alga generator, it is required to reduce the energy used for controlling the pitch of the foil.

In order to solve the above-described problems, the applicant of the present invention has proposed a first interlocking unit and a second interlocking unit in a manual multiple repetitive lifting power generator of Korean Patent Registration No. 1615334. The first interlocking unit transmits the rotational force of the rotational force transmitting portion of the first converting unit to the rotational shaft of the second A / O reciprocating unit, and the second interlocking unit transmits the rotational force of the rotational force transmitting portion of the second converting unit to the rotational shaft of the first A / , Thereby saving energy used for pitch control of the reciprocating member.

However, the first interlocking unit and the second interlocking unit proposed by the applicant of the present invention in the manual multiple repetitive lift-up type power generation apparatus of the Japanese Patent Registration No. 1615334 have a semi-passive power transmission system that uses only part of the energy used for pitch control There is a limit to stay in a semi-passive transmission structure.

That is, a motor for adjusting the inclination angle of the first reciprocating member is coupled to the first swing member so that only a part of the rotational force of the first converting unit is transmitted to the pitches of the second and third reciprocating members and the second reciprocating member And a motor for adjusting the inclination angle of the first B reciprocating member is coupled to the second swing member, so that only a part of the rotational force of the second converting unit is used for the first A-reciprocating member and the first B- It remains in the semi-manual power transmission structure used for pitch control of members.

On the other hand, the tidal generator and the tidal-pumped-water generator are operated within a certain range according to their operating capacity. As the flow rate of the algae fluctuates periodically, the tidal generators and the pumped pumped generators must be able to run smoothly, stopping and stopping, depending on the flow conditions.
