Abstract

A multiple oscillation-type generator includes: a first reciprocating member arranged inside a fluid and configured to reciprocate by lifting force, lowering force, or flow energy resulting from the fluid; a second reciprocating member arranged inside the fluid at a distance from the first reciprocating member and configured to reciprocate by lifting force, lowering force, or flow energy resulting from the fluid; a first conversion unit connected to the first reciprocating member and configured to convert reciprocating movements into rotational movements; a second conversion unit connected to the second reciprocating member and configured to convert reciprocating movements into rotational movements; a main power shaft configured to make rotational movements by rotational movements of the first conversion unit and the second conversion unit; and a generation unit configured to produce electric power using transferred rotational movements of the main power shaft.

First claim

What is claimed is:

a first reciprocating member arranged inside a fluid and configured to make a first ascending movement or a first descending movement within the fluid by a flow of the fluid;
a second reciprocating member arranged inside the fluid and configured to make a second ascending movement or a second descending movement by the flow of the fluid, the first and second reciprocating members being spaced apart from each other;
a first conversion unit connected to the first reciprocating member and configured to convert the first ascending movement or the first descending movement into a first rotational movement;
a second conversion unit connected to the second reciprocating member and configured to convert the second ascending movement or the second descending movement into a second rotational movement;
a main power shaft rotatably connected to the first conversion unit and the second conversion unit and configured to rotate by the first rotational movement or the second rotational movement; and
a generation unit connected to the main power shaft and configured to produce electric power using the first rotational movement or the second rotational movement,
wherein the first conversion unit comprises: a first conversion module configured to convert the first ascending movement and the first descending movement of the first reciprocating member into first bidirectional rotational movements,
wherein the first conversion module comprises: a swing member having one end coupled to the first reciprocating member; and a first rotation member coupled to the other end of the swing member and configured to make the first bidirectional rotational movements by the first ascending movement and the first descending movement of the first reciprocating member;
wherein the swing member and the first rotation member are arranged inside the fluid; and
wherein the first reciprocating member has a wing shape having a streamline cross-section and an inclination angle, and the inclination angle is configured to be adjusted to cause the first ascending movement or the first descending movement.

2. The multiple oscillation-type generator of claim 1 , further comprising:
a first one-way clutch configured to connect the first conversion unit and the main power shaft; and
a second one-way clutch configured to connect the second conversion unit and the main power shaft.

3. The multiple oscillation-type generator of claim 2 , wherein the first one-way clutch and the second one-way clutch are formed on the main power shaft.

4. The multiple oscillation-type generator of claim 2 , further comprising:
a first gear coupled to the second one-way clutch;
a second gear configured to rotate while being interlocked with the first gear; and
an auxiliary power shaft configured to rotate together with the second conversion unit and the second gear.

5. The multiple oscillation-type generator of claim 2 , further comprising:
a first pulley coupled to the first one-way clutch; and
a first belt configured to make a connection so that the first conversion unit and the first pulley are interlocked and rotated.

6. The multiple oscillation-type generator of claim 2 , further comprising:
a second pulley coupled to the second one-way clutch; and
a second belt configured to make a connection so that the second conversion unit and the second pulley are interlocked and rotated.

7. The multiple oscillation-type generator of claim 4 , further comprising:
a first crank coupled to the main power shaft and rotated together, the first crank having an eccentric center of gravity with respect to the main power shaft; and
a second crank coupled to the auxiliary power shaft and rotated together, the second crank having an eccentric center of gravity with respect to the auxiliary power shaft.

8. The multiple oscillation-type generator of claim 1 , wherein a fly wheel is coupled to the main power shaft.

9. The multiple oscillation-type generator of claim 1 , wherein the first conversion unit further comprises:
a second conversion module configured to convert the first bidirectional rotational movements into first unidirectional rotational movements.

10. The multiple oscillation-type generator of claim 9 , wherein the second conversion module comprises:
a first bidirectional rotation gear and a second bidirectional rotation gear configured to rotate in both directions by the first conversion module;
a first idler gear configured to engage with the first bidirectional rotation gear and rotate together;
a second idler gear configured to rotate together with the first idler gear;
a first output gear coupled to an output shaft and configured to engage with the second bidirectional rotation gear and rotate together;
a second output gear coupled to the output shaft and configured to engage with the second idler gear and rotate together;
a third one-way clutch configured to connect the first output gear and the output shaft; and
a fourth one-way clutch configured to connect the second output gear and the output shaft.
