Description
Technical field
The present invention relates to wind power generation plant, especially a kind of wind-driven generator roller type yaw device is suitable for a variety of
Large-scale wind driven generator used in type wind power plant, for impeller and electrification component being supported and being adjusted direction.
Background technique
Currently, large-scale horizontal axis wind generating device is widely used as clean energy resource power generator, mostly
Using the structure that three blade impellers are arranged on conventional boss, lower part is by yaw system and tower support and adjusts direction, by
Few in the blade of three blade impeller structures, aeroperformance is poor, in order to improve the working efficiency of blade, also has using full leaf point leaf
The structure of wheel type wind driven generator, which are mainly applied to large-sized wind-driven generators.The yaw system of use is also known as to wind apparatus,
It is that wind power generating set realizes all gravity of head and wind flutterred the important component for catching wind direction, while can also carry unit
All load generated are carried, can cooperate with the control system of wind power generating set, quick smoothly be directed at wind direction, so as to
Impeller obtains maximum wind energy.Yaw system generallys use installation frame in yaw bearing and sets on the rack as support platform
It sets yaw motor, yaw gear and yaw bearing assembly and realizes rotation, and adjusted windward by the control to yaw motor
Direction.
It is set to due to yaw device on tens meters high of single tower, with wind-driven generator enlargement, wind-force becomes
Change increases with it, and the weight of the impeller and generator assembly etc. as load is bigger, and load-bearing range is because of single-machine capacity size
Difference, ton differs from tens tons to more than 200, increasing along with wind-driven generator, transport and lifting are difficult, working condition requirement is high,
Stability is poor, high failure rate, structure is complicated high cost, and weight and height are again that single tower is supported, working condition requirement
Height, as impeller the more is made the more big, yaw bearing partial denudation outside, is encroached on vulnerable to pollutions such as sand and dust, salt fog, frosts, is used
Yaw structure be mostly rolling body bearing be difficult meet topple, load, impact these three power, stability is poor, be very easy to
Yaw bearing is caused to damage, maintenance, replacement are difficult.Therefore, to the improvement of above-mentioned wind-power generating yaw device, become this field
The object that technical staff generally studies.
The applicant discloses " the full leaf point wind-driven generator " that notification number is CN103147926B, and yaw platform uses
Upper and lower desk tray structure, between be equipped with yaw bearing, position-limited rack, making to be able to behave well in public rotates around leave from office disk center, and yaw bearing includes band
Have on the bearing of ring gear and to be enclosed under circle, bearing and scroll wheel.It uses the yaw platform of double-layer structure, still there is yaw axis bearing portion
It is point exposed outside, encroached on vulnerable to pollutions such as sand and dust, salt fog, frosts, be very easy to that yaw bearing is caused to damage, maintenance needs are torn open
Whole yaw bearings are unloaded, cause maintenance, replacement difficult；Yaw platform is fixedly connected with two racks on top, increases yaw
The weight of platform be easy to cause rotation not stable enough, or even occurs to connect with rack in the case where big wind-force and increase load
Connect unstable problem.It is bigger that therefore, it is necessary to load-bearing capacities, runs more stable and reliable yaw device as wind power generation plant
Support is provided.
Summary of the invention
The object of the present invention is to provide a kind of wind-driven generator roller type yaw devices, solve existing large-scale wind generating
