Description

Industrial application fields

  The present invention is utilized in a wide range of fields as an energy source by utilizing facilities from a low output machine to a high output machine due to low wind power operation, high power generation rate and economy.

  Conventional wind power generators are generally known to generate electricity with a single and unidirectional rotor, and it cannot be said that the increase in capacity of large-capacity machines and the high efficiency of wind power use match. Therefore, there are many things that are limited in the selection range of the installation location and the facility utilization rate.

Problems to be solved by the invention

  The development of highly efficient equipment that can be used even in places where the average annual wind speed is relatively low, and the miniaturization of equipment per unit of power generation will be promoted to increase the spread. For this purpose, the mechanism and materials will be improved to increase the rotational force and increase the power generation rate.

Means to solve the problem

Problem 1 When a wind power generator is combined with a plurality of vertical axis rotors (turbine type) and a plurality of horizontal axis rotors (propeller type) to increase the effective wind receiving area ratio (wind power utilization efficiency) and increase the rotational force At the same time, the generator is operated while the multiple operating torques generated from them complement each other. In addition, the power generation method is an output conversion type that efficiently generates power while automatically converting output following wind power, thereby further increasing the power generation rate and enabling operation to start in a relatively weak wind state.

Action

This wind power generator generates power by generating an operating torque with wind force acting on the horizontal axis rotors (1, 2) and the vertical axis rotors (5, 7). Each rotor is connected by a plurality of transmission devices (6) (bevel gears, friction wheels, etc.) having an arbitrary angle, and the assembled rotational torque operates the generator (11) via the speed increaser (10). Let Adjustment of the rotation direction of each rotor is performed by changing the direction of the blade in the case of the horizontal axis and the wind receiving direction of the bucket type blade in the case of the vertical axis. At that time, the rotors rotate in reverse on the same axis, so that each centripetal force cancels unidirectional blur due to the rotational force of each rotor and the acting force in a single direction, thereby rotating in the horizontal and vertical directions. It is possible to eliminate the inconvenient force of the cantilever beam acting on the center holding and the longitudinal center axis of the gantry (12) and the steel tower (13) (the effect of the gyro stabilizer can be utilized).
The swiveling operation is performed by the difference in area between the windward and leeward side blades and the swivel auxiliary blade (3). At that time, the one-way clutch (8) is set to turn in a certain direction while fixing each rotor. The vane area on the leeward side is always X times that on the leeward side, and X is set to a value that generates a necessary and sufficient turning force. The swivel portion is fixed to the swivel base (9) by the connecting column (4).
The attached drawings represent the principle of the power generation device.

  The operability of this method is proved mechanically and mechanically, and it is clearly shown that the operability and efficiency of this method can be fully demonstrated from the existing operation examples of the conventional method.

The invention's effect

Wind power utilization efficiency and power generation performance will increase, and the device will become more compact and more popular. Since the starting wind speed can be reduced, the range of use is expanded. In particular, due to the nature of this apparatus, it is highly convenient as a power energy source in a specific area, and the power transmission facilities at that time are not necessary, and at the same time, the influence of a wide-area blackout accident is eliminated or reduced.
Moreover, by promoting the development and popularization of this, it is possible to lower the price of electric power energy and contribute to the overall economic activity. Such high convenience and a reduction in power costs can be used to promote the development and popularization of power-utilizing traffic machines and various electric appliances. At the same time, it will reduce fossil fuel consumption, stockpiling costs and management costs, and it will also lead to countermeasures for accidents, air pollution and global warming.

  The horizontal axis rotors (1, 2) and the vertical axis rotors (5, 7) are connected by a central transmission (6), and the combined operating force passes through the speed increaser (10) to the generator (11 ). The swiveling operation is performed by the difference in area between the windward and leeward side blades and the swivel auxiliary blade (3). The one-way clutch (8) is for preventing reverse rotation. The swivel portion is fixed to the swivel base (9) by the connecting column (4). The gantry (12) fixes the entire apparatus, and the steel tower (13) is for providing a height according to installation conditions such as wind conditions.

Claims (1)

  By combining multiple vertical axis rotors (turbine type) and multiple horizontal axis rotors (propeller type) powered by wind power, the effective wind receiving area ratio (wind power utilization efficiency) is increased and the rotational force is complemented. At the same time, the device maintains the horizontal and vertical simultaneous equilibrium (gyro-stabilizer effect) and vibration reduction effect, and the power conversion type power generation method according to the strength of the wind power enables operation at a high power rate even in low wind conditions.
