Description

Technical Field

[0001] The present invention relates to the technical field of power conversion, in particular to the technical field of mechanical power transmission conversion, and specifically to a unidirectional power conversion power device and a power system having the device. Background Art

[0002] Wave power generation has advantages such as high energy density and never-ending operation, but the instability of its wave direction leads to unstable power output, low efficiency, and many other unfavorable factors that restrict the commercial promotion of the entire wave power generation industry. Most of the existing wave power generation technologies absorb wave energy in one or two directions. Not only is it difficult to absorb the irregular kinetic energy of waves in all directions, but it is also easily damaged by the impact of side waves. The Chinese invention patent application number is 201610214252.3, and the name of the invention is "Island Ocean Platform Universal Wave Power Generation Unit and Power Generation Device". This invention patent discloses a technology that can convert rotational kinetic energy in two swinging directions. The first swinging direction is the lateral swing of the swing input shaft, and the second swinging direction is the longitudinal swing of the swing box. When the swing box swings longitudinally, for example, the longitudinal swing rotates to the left, its kinetic energy can convert the lateral swing of the swing input shaft. The power and the longitudinal rotational power of the swinging rotating shell are superimposed on the power output shaft; but when the swinging rotating shell rotates longitudinally to the right, the rotational power of the swinging rotating shell can only rely on the gears in another gear box to change the rotational power of the swinging rotating shell and drive the power output shaft. However, the swinging rotational power generated by the swinging input shaft on the swinging rotating shell will be offset or invalidated due to the reverse rotation of the rotating shell. Because the rotation direction of the rotating shell is opposite to the rotational power output direction of the bevel gear, they offset each other or become invalid, thereby reducing the energy absorption conversion efficiency. On the other hand, it also increases the instability of the power output, resulting in excessive fluctuations in the power output. Summary of the invention

Specifically, the first one-way clutch 9 and the second one-way clutch 10 are installed inside the swing rotating component 19. When the swing rotating component 19 receives an unstable power source to swing laterally, the first transmission shaft 15 and the second transmission shaft 16 are alternately driven to move under the action of the first one-way clutch 9 and the one-way clutch 10, thereby driving the seventh bevel gear 7 and the eighth bevel gear 8 to move.

It should be noted that in the present invention, the number and structural combination of gears inside the swing box 20 are not completely limited.

The gear box in this part can be understood as a one-way gear box 18 or a swing housing 20 depending on the reference object. Therefore, the name of its internal gear combination may also change with the change of the name of the gear housing, and should be understood in a broad sense here.
