ある。An example thereof will be explained based on FIG. In FIG. 2, reference numeral 101 is a horizontal axis type wind turbine consisting of a wind turbine device 1o2, a rotating shaft 103 for rotating the wind turbine device 102, a nacelle 104, etc., and 105 is fixed to a frame 106, and a reduction gear 1
It is controlled by a motor connected directly to the wind vane (not shown) in response to a signal from the wind vane (not shown). 108 is a pinion (small gear) fixed to the shaft 109 of the reducer 107, and 110 is a pinion (small gear) fixed to the shaft 109 of the reducer 107. A rack (large gear) 111 fixed to the lower part of the meshing nacelle 104 is a bearing provided so that the rack 110 and the frame 106 can rotate relative to each other.
以上のように構成された風車の方位可変装置について、
以下その動作について説明する。Regarding the wind turbine azimuth variable device configured as above,
The operation will be explained below.

105の動力により減速機107を介してビニョン10
8を駆動する。If the wind is blowing from the direction of arrow A, the windmill tool 102
rotates vigorously, but if the wind direction changes,
Since the rotation becomes poor, the wind turbine 101 must be oriented in the direction of the wind. In this case, the wind vane senses the wind direction and the motor 105 uses the power to drive the binon 10 through the reducer 107.
Drive 8.

発明の目的
本発明は上記欠点に鑑み、風の力によって風車が強制的
に方位を可変されるときでも、旋回機構を保護できる、
風車の方位可変装置を提供するものである。However, with the above configuration, if the wind is strong and the wind direction changes rapidly, for example, if the wind suddenly blows from right next to you, the wind turbine device 102 will be pushed by the wind and the wind turbine 101 will be forced to turn. In order to be forced to do so, this time, on the contrary,
0 is driven and the vinyl controller 108. Motor 105 is driven via reduction gear 107 . At this time, if the rotation speed of the wind turbine 101 is high, the rotation speed of the motor 105 of the rotation mechanism 112 driven by the wind turbine 101 becomes over-rotated, resulting in damage to the motor 105. In view of the above-mentioned drawbacks, the system can protect the rotating mechanism even when the direction of the wind turbine is forcibly changed by the force of the wind.
The present invention provides a wind turbine azimuth variable device.

The power motor is controlled by a signal from a wind vane (not shown). 7 is a centrifugal force clutch, one of which is directly connected to the shaft 8 of the motor 5 and the other directly connected to the shaft 8' of the reducer 9, which is attached and detached depending on the magnitude of centrifugal force; 1Q is a pinion ( 11 is an annular rack (large gear) that meshes with the pinion 10 and is fixed to the lower part of the nacelle

。In FIG. 1, when the wind is blowing from the direction of arrow B, the wind turbine blades 2 are rotating vigorously. Next, when the wind direction changes, in order to orient the wind turbine 1 to the wind direction, the shimotor 5 is driven by a signal from a separately provided wind vane (not shown), and the shaft 8 is driven by its power. When the shaft 8 is driven and reaches a certain rotational speed, the centrifugal force of the rotation activates the centrifugal force clutch 7, and the rotational power of the shaft 8 is transmitted to the shaft 8' of the speed reducer 9. The pinion 10 is then driven via the shaft d'. When the binon 1Q is driven, the rack 11 that meshes with it is driven, and the wind turbine 1 turns together with the nacelle 4 to face the direction of the wind. After that, when the direction of the windmill 1 is facing the direction of the wind, the wind vane indicates that the shimmotor 5 is stopped. Therefore, at this time, the shaft 8 of the motor 5 also stops rotating, and at the same time, the operation of the centrifugal clutch 7 is also stopped. @8 and shaft 8' are separated by 9, respectively.

Even if the rack 11. The signal is only transmitted to the shaft 8' of the reducer 9 through the pinion 10° shaft 8'', and the shaft 8 of the motor 5 is not driven. Therefore, the motor 5 is not driven in the opposite direction by the rotation of the windmill 1. It will not be damaged by over-speeding.
