Problems solved by technology
If the yaw system fails in bad weather such as typhoon, the power of the wind turbine is lost, and the power of the UPS backup power supply is insufficient, the yaw motor of the electromagnetic power failure brake will be locked, and the impeller cannot yaw to the downwind direction to face the wind. At this time, the wind load of the wind turbine is too large, resulting in damage to the wind turbine
[0006] In addition, when the yaw hydraulic circuit fails, the brakes cannot perform yaw braking, and cannot perform yaw braking and locking on the wind turbine, and cannot guarantee that maintenance personnel can safely repair the yaw hydraulic circuit

Embodiment Construction
[0027] According to an embodiment of the invention, the yaw braking of the wind park is achieved by means of the interaction of the braking part moving at the height of the wind park with the brake disc in the horizontal plane.
[0028] Preferred embodiments of the present invention are described below with reference to the accompanying drawings, in which like reference numerals refer to like parts throughout.
[0029] figure 1 is a schematic diagram showing the installation manner of the yaw brake device according to the embodiment of the present invention.
[0030] Such as figure 1 As shown, the wind power generating set may include a tower 12, a yaw bearing 30, a yaw driving device 3, a nacelle base 11 and other components.
[0031] The yaw bearing 30 may have an inner ring (not shown) and an outer ring, the outer ring may have outer ring teeth 40, the tower 12 may be connected to the outer ring of the yaw bearing 30 by fixing means (eg, bolts and nuts), The nacelle base...

The invention provides a wind turbine generator system and a yaw brake device for the same. The yaw turbine generator comprises a brake shaft, a first gear, a brake disc and a brake unit, wherein thebrake shaft is mounted at the outer side of a cabin base or a tower of the wind turbine generator system, the first gear sleeves the brake shaft and can rotate, together with the brake shaft, around the axis of the brake shaft, and meshes with the outer gear ring of a yaw bearing of the wind turbine generator system, the brake disc sleeves the brake shaft and can rotate, together with the brake shaft, around the axis of the brake shaft, the brake unit includes a brake part which is capable of moving along the axis of the brake shaft and touching the upper end face or lower end face of the brake disc. According to the embodiment of the yaw brake device, the yaw brake device can provide a guarantee to normal yaw and normal yaw brake of the wind turbine generator system.
Description
technical field [0001] The invention belongs to the field of wind power generation, and more specifically relates to a yaw braking device for a wind power generating set and the wind generating set. Background technique [0002] Wind turbines generally include impellers, generators, nacelles, towers and other components. When it is necessary to yaw the wind generating set, for example, when the wind direction changes, it is necessary to adjust the yaw of the wind generating set to adjust the impellers of the wind generating set to a windward direction, thereby making full use of wind energy. [0003] A yaw system of a wind power generating set generally includes a yaw bearing, a yaw driving device (eg, a yaw motor), a yaw brake (eg, a brake), and a yaw hydraulic circuit. [0004] The yaw system feeds back the wind direction signal collected by the anemometer to the control system. The control system compares the wind direction information with the position of the nacelle of...
