Technical Field
The utility model relates to a yaw assembly of a wind generating set and the wind generating set comprising the yaw assembly.
Background
With the rapid development of economy, the world environment is also greatly destroyed, and in recent years, various severe geological disasters frequently occur around the world, so that environmental protection problems are attracting more and more attention. Wind power is used as a clean energy source, wind energy is utilized to convert the wind energy into electric energy, the emission of carbon dioxide can be greatly reduced, and the environment protection is facilitated. After the development of more than 20 years, the land high-quality wind resources are basically developed, and the eyes of people start to turn to offshore, open sea and even deep.
The yaw system is used as an important component of the wind generating set and has the functions of capturing wind energy to the maximum extent, thereby improving the utilization rate of the wind energy and improving the generating capacity. However, the offshore wind conditions are complex, wind load is large and variable, the period of a sea outlet window is short, typhoons are particularly likely to occur at any time, once a unit breaks down and is limited by sea outlet conditions, a tower falling is extremely easy to occur, and great challenges are presented to the reliability of a yaw system to a certain extent, so that how to effectively improve the yaw capacity of an offshore wind turbine generator system becomes an important problem to be solved by each host manufacturer.
In the existing offshore wind turbine generator systems, the yaw capacity of the wind turbine generator system is mostly improved by simply increasing the number of yaw drives, namely, more yaw drives are arranged by increasing the diameter of a cabin seat. The disadvantages of the above method are the following three: firstly, the diameter of the cabin seat is increased, the volumes of the corresponding transmission chain and the cabin cover are also increased, the weight increasing and increasing effects are obvious, and the increase of the cost is not neglected; secondly, the flange surface for installing yaw drive on the engine room seat is wing-shaped compared with the engine room seat body, when the unit bears larger wind load, the more the yaw drive is arranged on the engine room seat, the larger the amplitude of upward bending deformation of the flange surface is, so that the engagement of yaw drive teeth and a yaw gear ring is not facilitated, and the service life of each structure in the yaw drive is also not facilitated; thirdly, when the diameter of the cabin seat is fixed, the maximum number of yaw drives which can be arranged on the cabin seat is also fixed, and as is well known, the wind load of the unit is obtained through simulation calculation and is generally deviated from the wind load of an actual project site, if the yaw drives are arranged according to the maximum number, once the actual wind load of the unit exceeds the simulation design load, the stability of the unit faces a great test due to the fact that a redundant yaw drive interface does not exist.

The wind turbine yaw assembly 1000 according to an exemplary embodiment of the present utility model may include: the gear ring comprises an annular ring and a tooth part positioned on the annular ring; the base 100 includes an upper flange portion and a lower flange portion having a plurality of mounting holes, respectively, with the ring gear being located therebetween; a yaw drive part 300 having drive teeth, which are mounted to at least one mounting hole of the upper flange part and/or at least one mounting hole of the lower flange part, and which are capable of being engaged with the teeth part.
As shown in fig. 5 and 6, the ring gear in the wind turbine yaw assembly 1000 may be an outer ring gear 210, and the teeth include a first tooth 211 and a second tooth 213 arranged on an outer side surface of the annular ring and separated from each other along an axial direction of the annular ring.
The yaw assembly of the wind generating set according to the exemplary embodiment of the utility model can realize the simultaneous driving of the yaw driving parts of the upper layer and the lower layer, and the redundant interfaces of the yaw driving parts are added, so that the number of the yaw driving parts can be determined according to the corresponding loads.

In addition, the first and second yaw drives 300 and 300 are respectively arranged at equal intervals along the circumferential direction of the base 100.
Although the yaw driving part 300 is provided in each of the mounting holes of the upper flange part and each of the mounting holes of the lower flange part in fig. 5, the present utility model is not limited thereto. According to an exemplary embodiment of the present utility model, the yaw driving part 300 may be disposed in one or more of the plurality of mounting holes of the upper flange part and the plurality of mounting holes of the lower flange part according to an actual load.
According to an exemplary embodiment of the utility model, wind turbine yaw assembly 1000 may further include a passive yaw brake 400, passive yaw brake 400 mounted inside foundation 100 and engaged with engagement surface 214 of outer ring gear 210.
Although the ring gear in the wind turbine yaw assembly shown in fig. 5 and 6 is an external ring gear, the present utility model is not limited thereto. The ring gear in the wind generating set yaw assembly according to an exemplary embodiment of the present utility model may be an inner gear ring, and the teeth portion includes first and second teeth portions disposed on an inner side surface of the annular ring and separated from each other along an axial direction of the annular ring.

When the offshore wind turbine generator system stops yawing and needs to be braked, the redundant yaw driving part of the lower flange part can also provide a certain braking force. For example, the yaw drive section typically includes a yaw motor and a yaw retarder, and when braking is required for off-shore wind turbine generator sets to stop yaw, the redundant yaw drive section of the lower flange section may also provide a braking force by electromagnetic braking of its own in the yaw motor. Through the mode, the yaw speed reducer is prevented from being reversely dragged to lose efficacy due to overlarge wind load, and the stability of the unit is further affected.
