状態においては、油圧回路６を流れる油圧は低いため、
油圧ポンプ１の駆動トルクも小さく、したがって風車２
はスムースに回転できる。Regarding the wind turbine power transmission device configured as described above,
The operation will be explained below. First, the force of the wind turbine causes the wind turbine 2 to rotate and the hydraulic pump 1 to be driven. When the wind is weak and the wind turbine 2 is stopped or the rotation speed is low, the generated power is also small, so in order to reduce the rotational load on the wind turbine 2, the rotation signal from the tachometer 3 is sent to the controller 11.
This signal is used to control the flow rate adjustment valve 6, and a portion of the oil flowing through the hydraulic circuit 5 is caused to flow through the bypass circuit 4 and the flow rate adjustment valve 6 as shown by the arrow. In such a state, the oil pressure flowing through the hydraulic circuit 6 is low, so
The driving torque of the hydraulic pump 1 is also small, so the wind turbine 2
can rotate smoothly.
次に風車２の回転数が上昇した場合には、同様に回転計
３の回転信号を制御器１１により検出し、この信号にて
流量調整弁６を制御してバイパス回路４を流れる流量を
制限すると油圧回路５を流れる油は圧力を上げつつ油圧
モータ７に流れるようになシ、油圧モータ７および空気
圧縮機９が駆動される。かくして、風車２の回転動力は
動力伝達部８を介して空気圧縮機９に伝達されたことに
なる。Next, when the rotation speed of the wind turbine 2 increases, the rotation signal of the tachometer 3 is similarly detected by the controller 11, and this signal controls the flow rate regulating valve 6 to limit the flow rate flowing through the bypass circuit 4. Then, the oil flowing through the hydraulic circuit 5 increases its pressure and flows to the hydraulic motor 7, thereby driving the hydraulic motor 7 and the air compressor 9. Thus, the rotational power of the wind turbine 2 is transmitted to the air compressor 9 via the power transmission section 8.
逆に風車２の回転数が下降してきた場合には同様に流量
調整弁６を制御してバイパス回路４を流れる流量を増加
させることにより油圧回路５を流れる油圧を低下させ、
油圧ポンプ１の駆動トルクを軽減して風車２の回転負荷
を軽くする。Conversely, when the rotational speed of the wind turbine 2 decreases, the flow rate regulating valve 6 is similarly controlled to increase the flow rate flowing through the bypass circuit 4, thereby decreasing the oil pressure flowing through the hydraulic circuit 5,
The driving torque of a hydraulic pump 1 is reduced to lighten the rotational load of a wind turbine 2.

The power transmission section is composed of a bypass circuit having a flow rate adjustment valve, and a controller that receives a signal from a tachometer and controls the flow rate adjustment valve, and controls the power transmission section based on the rotational speed signal.
