Abstract

PURPOSE: To improve the wind power energy conversion ratio and the power generation efficiency by mounting rotors of a plurality of systems and generators of a plurality of systems where a wind force interlocking type automatic torque adjusting device with the wind force as the source is interposed. CONSTITUTION: Rotors 1, 2 drives generators 14 to generate power by the wind force in the constantly right or left direction through a rotary shaft 6, a driving bevel gear 5, a driven bevel gear 7, and a speed increasing gear 11. Among a plurality of connected generators 14, the first generator is directly connected to the speed increasing gear 11 but the second and subsequent ones are operated by interposing a clutch 12 in a unit box 13 which is set according to the wind force and has the specific number of revolution. A turning table 9 to be adapted to the change in the wind direction is operated by the turning force of the rotors 1, 2 by the wind force and an auxiliary turning blade 3, and a guide wheel 10 supports the turning table.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention has a wide range of conveniences from low-powered machines to high-powered machines due to low wind power operation, high power generation efficiency, light weight, and economical efficiency, and can be used for general households, buildings, high-rise apartments, and production plants. It is used as an energy source.

[0002]

2. Description of the Related Art Conventional wind power generators are generally known and exist in which power is generated by a singular type rotor and a singular type generator. In addition, even with multiple systems, there is a system that automatically adjusts the rotational torque by setting the operating speed and speed multiplication factor of the rotor and the clutch used in this system to specific values depending on the conditions of the installation location. Absent.

[0003]

[Problems to be Solved by the Invention] Development of a highly efficient power generator which can be used even in a place where the annual average wind speed is relatively low, and reduction of the weight of the device per unit amount of power generation and economic efficiency, convenience and spread Increase.

[0004]

[Means for solving the problem]

Problem 1 Wind energy and the rotational torque obtained from it
Power generation is started from low wind power by interlocking with an automatic torque adjustment device that uses wind power itself as a power source at the time of input and at the time of generator operation. In addition, the rotor and the on-board generator are used in multiple systems, and the torque adjustment device set according to the wind conditions at the installation site is used to improve the rotational power operation efficiency during start-up and operation and to improve wind energy conversion rate and power generation efficiency. Improve.

[0005]

[Operation] The greatest feature of this generator is that "a unique value is set for the speed-up factor and the operating speed of the clutch for each generator" in order to realize the minimum starting torque and the maximum power generation efficiency. The calculation of the set numerical value is determined by the rated output of the device and the wind conditions of the installation location, and at the same time, the maximum rotational speed of the rotor is set to a numerical value within a specific limit compatible with this. The operation of the device is that the rotors (1, 2) attached to both ends of the rotary shaft (6) receive wind force and generate a rotation torque, and the rotation torque is stored in the unit box (13) according to the change in wind force. Automatic torque adjustment device (speed increasing gear 1
It is adjusted with 1 clutch 12). The generator (14) is of a vertical type, and is connected to the unit box by a flange type, and is connected to the rotating shaft by a bevel gear that also serves to increase the speed. The attached drawings explain the principle of a two-generator system.

[0006]

[Embodiment] From the existing operation example of the conventional method, it is clarified that the operability and efficiency of this method can be sufficiently exhibited and is possible.

[0007]

Since the wind energy conversion rate and the power generation efficiency are remarkably increased, not only large size but also small and medium output type can operate efficiently. In addition, the required wind speed for starting operation is significantly reduced, so the installation conditions and range are significantly expanded,
Convenience and economy are enhanced. Therefore, it is widely used in ordinary households and buildings,
It can be spread to high-rise apartments, production plants, etc.
Since it can be applied to electric vehicles, electric bicycles, and other general electric appliances by installing a charging device, their R & D and manufacturing / sales will be promoted. In addition, the spread of this power generator will reduce oil and gas consumption, storage and management costs, and reduce accidents and disasters. In addition, it will lead to warming of the atmosphere and reduction of pollution such as exhaust gas.

[Brief description of drawings]

FIG. 1 is an overall view of an operating unit of a wind turbine generator. The rotors (1, 2) receive wind force from a certain direction of the left and right sides of the figure and generate electric power through a rotating shaft (6), a driving bevel gear (5), a driven bevel gear (7), and a speed increasing gear (11). The machine (14) is operated to generate electricity. Of the multiple generators that are connected, one operates directly connected to the speed increasing gear, but the second and subsequent units operate in unit boxes (13) that have a specific operating speed that is set according to the wind force. ) Clutch (1
Operates with 2) interposed. Rotors on both sides with the same number of blades shall be installed with offset by half of the blade mounting angle regardless of whether the number of blades on each rotor is odd or even in order to improve wind energy conversion efficiency. The operation of the swivel base to cope with the change in the wind direction is performed by the swivel force of the rotor itself by the wind force and the swirl assisting vanes (3), and the guide wheel (10) assists it.
