If so, the above structure constitutes a complete (5) 6 201209278 new wind turbine fault safety protection structure. The tilting driver 6 1 is a hydraulic motor, and the hydraulic source can be connected from the accumulator 6 3 , and the hydraulic source can be controlled to enter the first port 5 5 or the second port 5 6 to generate a change. The rotational power of the blade 5 3 is transmitted through the bevel gear 54 to transmit the rotational power so that each blade 53 can be changed to an inclination angle of 0 to 90. Between the ranges, the direction of rotation of each blade is changed, and the angle of inclination of each blade is changed. The invention is composed of the above components, and is in operation (as shown in Fig. 2). Mold 1 sudden power failure or emergency When the battery of the device is not required, the cooperation of the hydraulic circuit 6 2 and the accumulator 6 3 will cause the blades 5 3 to rotate to the minimum angle of the wind (such as the first Figure 9〇.), so that the wind turbine will then run at idle speed until the stop to avoid the damage caused by the wind turbine over-speed or overload caused by fail-safe protection. Further, referring to "Fig. 4 to Fig. 7", the blade inclination angle 90 is an embodiment of the present invention.

As shown in the figure: when the present invention is used, the steering unit 1 2 of the bracket 1 is combined with a column 7 for use as a erection, and the steering unit 1 2 can cooperate with the column 7 to rotate the bracket 1 So that the rotating unit 5 can be adjusted to the windward side according to the wind direction; and when it is operated, 'the blades 53 of the rotating unit 5 are rotated by the wind' and simultaneously rotate the shaft 51 to make the shaft 51 The mechanism in the generator 4 is interlocked to cause the generator 4 to generate electric power; at this time, the inclination angle of each blade with respect to the shaft 51 is about 0 to 5. . If the power failure suddenly occurs during the operation of the wind turbine, the solenoid valve 6 2 4 of the hydraulic circuit 6 will be returned to its original position by its spring 201209278 spring (as shown in Figure 3), so that the accumulator 6 3 The hydraulic source will flow through the solenoid valve 624 to the first port 5 5 to drive the vanes 5 3 to an angle of 90. (as shown in Figures 1, 4, and 5), and with this check width 6 2 1 to prevent external forces from changing the angle of inclination of each blade 5 3, to achieve the function of safe shutdown; when other emergency situations need to stop, it is The controller 2 1 in the control box 2 issues a command and transmits the command to the proportional valve 6 2 2. The logic valve 6 2 3 and the solenoid valve 6 2 4 actuate and actuate the solenoid valve 6 2 4 The valve is returned to the original position due to the spring bounce, so that the hydraulic source in the accumulator 63 will flow through the solenoid valve 6 24 to the first port 5 5 to drive the blades 5 3 to an inclination of 90. (As shown in Figures 1, 4, and 5), and with the check valve 612, the external force is prevented from changing the angle of inclination of each of the blades 53 to achieve a safe shutdown. When the operation is to be resumed, the proportional valve is actuated to move the hydraulic source through the logic valve 6 2 3 and the proportional valve 622, and flows to the second port 56 to drive the blades 53 back. To the point of close operation (such as Figures 6 and 7), this can avoid damage to the wind turbine caused by power failure, so as to completely achieve the purpose of fail-safe protection. In summary, the present invention is a fault safety protection structure of a wind power generator, which can effectively improve various shortcomings of the conventional use, and can utilize the cooperation of the hydraulic circuit and the accumulator when a power failure or an emergency situation occurs during the operation of the generator. Immediately rotate the blades to the stop angle to avoid damage to the wind turbine, and to achieve the effect of fail-safe protection, so that the invention can be more advanced, more practical, and more in line with the user's compliance.
