Description

  The present invention relates to a wind turbine generator.

Power generation devices are roughly classified as conventionally known ones, and various large-scale power generation devices such as wind power generation devices, steam power generation devices, hydroelectric power generation devices, wave power generation devices, and solar power generation devices have been developed.
In recent years, the global warming problem has surfaced, and carbon dioxide emission regulations have been exclaimed. As a clean energy technology to cope with this, the above-mentioned solar cells, wind power generation and the like have been noticed and developed and are currently in operation, but the current situation is that they are not widely used due to problems such as cost and maintenance.

  Therefore, there are eccentric rotating power generators described in Patent Document 1 to Patent Document 3 in the past. These are devices that utilize gravity on the earth as an eccentric rotating device for power generation devices, and efficiently convert them into rotational energy for power generation. This eccentric rotation device is a device that drives the rotation using a natural driving force such as wind power, steam power, hydraulic power, wave power, etc., with a rotational drive shaft for power generation rotation as drive energy, and is a device that greatly increases electric energy conversion efficiency. . This eccentric rotating device is horizontally arranged perpendicular to a position displaced by a predetermined amount in the horizontal direction from the center position of the vertical circular ring rail and the circular magnet guide type or roll guide type ring rail. A rotational drive shaft, a guided shaft mounted on the rotational drive shaft via an eccentric rotation guide shaft mechanism and provided with a permanent magnet or a guide roll so as to be able to circulate along the ring rail, and a fly weight mounted on the guided shaft. Is the main component. The vertical perfect ring ring rail has a permanent magnet for guide or a roll guide rail fixedly arranged so that the guided object faces. Thus, the guided member can follow the ring rail and travel around the ring. The eccentric rotation shaft mechanism is slidable along the rotational radial line of the horizontal rotation drive shaft and supports the guided member at intervals of a rotation angle of 180 degrees. The eccentric rotation shaft mechanism is rotated by the horizontal rotation drive shaft, and the counterweight mounted on the type guided guide is rotated eccentrically, whereby the rotation moment (the moment of force around a predetermined rotation shaft is determined as the torque). To be rotated with a light load.

  This eccentric rotation device is an efficiency that reduces energy loss by rotationally driving the horizontal rotation drive shaft using a small engine, hydraulic power, wind power, wave power, other natural energy, or fine electric power obtained therefrom. Ensuring good power generation is the biggest goal. However, it reduces the rotational resistance of the guided gear that circulates along the pair of left and right ring rails, reduces the sliding resistance between the guided gear and the eccentric rotating shaft mechanism that cooperates with the fly weight, and further affects the eccentric rotating shaft mechanism. There are contact type and non-contact type that devise the axial force distribution during rotation, both of which have problems with the complexity of the mechanism and the accompanying rotation resistance and axial force distribution.

  In a conventional eccentric rotating device, an eccentric rotating shaft mechanism that is guided by a pair of left and right magnet ring rails arranged with fixed permanent magnets and rotates between the ring rails, a permanent magnet type guided member, and a rotation weight position of the fly weight. There are a rotational moment generation region applied to the horizontal rotation drive shaft for rotation in the intended leftward rotation direction (→ forward rotation direction) and a region where a rotational moment is generated in the reverse rotation direction.

  In the eccentric rotating device, the pair of ring rails are made into perfect circles, and the rotation center position of the eccentric rotating shaft mechanism is shifted to a position of one third of the horizontal diameter line of the perfect circular ring rail. For this reason, for example, the eccentric rotation shaft mechanism is linear, and the offset rotation shaft mechanism is rotated horizontally by placing equal weight fly weights including guided parts on both sides, that is, at 180 ° rotation angle intervals. When the drive shaft is rotated, there is a region in which a pair of guided and its fly weights exist together in a single arc portion on the rotation center side of the eccentric rotary shaft mechanism from a vertical line passing through the center of the ring rail. . Outside this region, the horizontal rotation drive shaft is a region where a rotational moment for rotating in the intended left rotation direction is always applied. The region is a region sandwiched between two positions where the left and right rotational moments are in the same neutral state, and while the pair of guides and their counterweights are located in this region, the horizontal rotation drive shaft core is always shown in the figure. A counter-rotating load in the clockwise direction is applied, causing energy loss, decelerating, causing large rotation fluctuations and unstable.

  An invention in which a ring rail is formed into an oval shape in an attempt to eliminate a region where a rotational moment is generated in the reverse rotation direction is introduced in Patent Document 4, and an invention in which the ring rail is combined with a semi-longitudinal ellipse and a semi-horizontal ellipse is disclosed. It is introduced in Patent Document 5. However, both of the inventions of the vertical type (vertical type) and the pair of left and right complex egg-shaped ring rails and vertical / horizontal semi-elliptical ring rails are extremely difficult to design and manufacture, The improvement of the axial force distribution applied to the rotary drive shaft and the reduction of the rotational resistance were not satisfied.
