Description

Directional control device for rotating shaft for vertical axis wind power generator and rotational force generating device using same

The present invention relates to a direction control device for a rotary blade for a vertical axis wind turbine and a vertical axis wind generator, and a rotational force generating device using the same, and more particularly, in the vertical axis wind power generator to receive the maximum forward wind power of the rotary blade in reverse rotation of the rotary blade The present invention relates to a direction control device for rotating blades for a vertical wind turbine for sensing wind direction and to adjust a direction of a rotating blade in order to minimize wind power, and a rotation force generator including the rotating blade using the same.

Wind generators are divided into horizontal shaft generators and vertical shaft generators according to the main shaft installation method. Propeller-type horizontal shaft generators with rotating blades installed on the horizontal shaft should have a wind speed of 6-15 [m / s] for rated power. It can be installed in a few specific areas due to low wind speed. In low wind speed area of 2 ~ 5 [m / s] inland or coast, it is possible to install a vertical axis generator equipped with a rotating blade on the vertical axis that can rotate constantly regardless of the wind direction. I use it. However, since the rotating blades used in the vertical shaft generator are fixed to the connecting tube attached to the rotating body, the rotating blades do not rotate at any position revolved about the main axis, and thus the rotating blades receive the reverse wind force. And, because it forms the angle of the rotating blade that does not receive wind at all, the efficiency of wind power generation is weak because it can not transmit the rotational force to the main shaft. In addition, in the case of using a cup-shaped blade, only the wind vane can use the wind power of the cup wing of the concave portion facing the wind direction, and only half of the wind power is used. This problem, the door-type blade is open to the reverse side wings to reduce the resistance of the wind, but the power required for rotation is only half of the blade has a problem of low power generation efficiency.

As an invention for improving the power generation efficiency of the door-type blade as described above, Patent Publication No. 10-2002-0023795 (published date: March 29, 2002) of the 'angle conversion device for a vertical axis wind turbine generator' Was released. As shown in FIG. 1, as shown in FIG. 1, a rotor is fixed to an upper end of a main shaft installed in a pipe tower and connected to a generator and a speed increaser. In a fixed vertical axis wind power generator, a rotating body is installed in which a bevel gear and a sun gear are meshed therein, and the sun gear is supported by a radial bearing installed at the top of the rotating body at its center. It is fixed by a wind vane rotary shaft and a key connected to a wind vane (1) supported by a bearing thrust bearing installed on the bottom of the rotating body and penetrating the hole formed in the upper part of the whole, the planetary gear is composed of a rotating gear consisting of a driven gear and a driven gear of the bevel gear It is connected to the gear shaft installed to be supported by a plurality of radial bearings inside the drive pipe of the device and the connecting pipe (3) attached to the rotating body. The driven gear is supported and penetrated by radial bearings installed at the upper and lower parts of the rotating device at the center thereof and fixed with a rotating blade shaft and a key to which the rotating blade 2 is attached at the upper and lower parts of the rotating device. And the number of teeth of a driven gear in a ratio of 1: 2 and the number of teeth of a planetary gear and the number of teeth of a driving gear in a ratio of 1: 1.

As disclosed in FIG. 1, the bevel gear formed integrally with the lower part of the wind vane 1 rotates according to the rotation of the wind vane 1, and the planetary gear meshed with the bevel gear rotates. The angle of the rotary blade 2 is to be converted. The disclosed invention is the wind vane (1) coupled to the bevel gear in the process of generating a strong rotational force on the rotating body through the connecting pipe (3) is rotated by the rotary blade (2) Should always be in the position of the wind direction despite the strong rotational force of the rotor. That is, the wind vane 1 can always detect the wind direction accurately and be able to change the angle of the rotary blade 2 through the bevel gear to achieve the object of the present invention.

However, since the rotational force of the rotary blade 2, that is, the rotational force of the rotor, is strong, the planetary gear can rotate the bevel gear regardless of the change of the wind direction by the rotational force. That is, the planetary gear should be subordinate to the rotation of the bevel gear. In the configuration of the present invention, the planetary gear may rotate the bevel gear. Therefore, the wind vane 2 installed above the bevel gear can be rotated in a direction different from the wind direction. If so, there is a problem that the angle conversion according to the wind direction of the rotary blade 2 can not be made accurately.

Therefore, there is a need for an invention in the vertical axis wind power generator that can accurately convert the direction of the rotary blade according to the change of the wind direction.

The present invention is to solve the problems of the prior art, an object of the present invention is to adjust the direction of the rotary blade of the vertical axis wind power generator, which can accurately adjust the direction of the rotary blade of the vertical axis wind turbine according to the wind direction and generating a torque using the same To provide a device.

As a technical solution for achieving the object of the present invention, a first aspect of the present invention is a rotating shaft, at least one vertical shaft rotating blade coupled to the rotating shaft for transmitting a rotational force, installed on the upper side of the rotating shaft A wind vane, a sensor coupled to the wind vane for sensing a rotation angle, a motor, a motor controller for controlling the driving of the motor by receiving a detection signal from the sensor, and a rotation coupled to the shaft of the motor. A bevel gear and a direction control device for a vertical shaft wind turbine rotating blade including a planetary gear for meshing with the bevel gear and transmitting the rotating force of the bevel gear to the rotating blade are provided.

According to a second aspect of the present invention, at least one vertical shaft rotating blade coupled to the rotating shaft and coupled to the rotating shaft to transmit rotational force to the rotating shaft, and installed at an upper side of the rotating shaft to detect a wind direction and change direction according to the wind direction. A main wind vane, a bevel gear coupled to the main wind vane and rotating together with the main wind vane, and a planetary gear for meshing with the bevel gear to transmit rotational force of the bevel gear to the rotating blade; A direction of the rotary blades for the vertical wind turbine including the at least one sub wind vane installed to be spaced apart from the wind vane, and configured to transmit the rotational force of the sub wind vane to a bevel gear coupled to the main wind vane. An adjusting device and a rotating force generating device using the same are provided.

According to the present invention, since the main wind vane and the plurality of sub wind vanes are integrally formed to change directions according to the wind direction, the bevel gears subjected to the rotational resistance by the rotational force of the rotating blades are the main wind vane and the plurality of sub wind vanes. By receiving a strong resistance force of the wind vane of the wind vane is not affected by the rotational force of the rotary blade, there is an effect that can accurately transmit the wind direction sensing rotational force of the main wind vane and the sub wind vane to the planetary gear.

Preferably, the mutual angle between the rotary blade 70 and the opposite rotary blade corresponding thereto is always set to be orthogonal. By doing so, it is possible to maximize the forward wind of the rotating blades in the vertical wind turbine and minimize the reverse wind of the rotating blades. In addition, the positive pressure and the constant pressure act on the rotary blade 70 at the same time can use the wind power in the best state.
