Abstract
A wind facing device of a wind generating set belongs to parts of the wind generating set, and is characterized in that a sensing-element wind vane is electrically connected to a processor of a yawing motor controlcircuit, the yawing motor is connected with a yawing planetary gear reducer and fixed on an engine room pedestal, an output gear of the yawing planetary gear reducer meshes with a yawing-bearing annular gear, the yawing-bearing annular gear is fixedly connected with a tower cylinder through a stepped-drum connecting piece, and a yawing-gear outer ring is fixed on the engine room pedestal. The change of wind direction is perceived by the wind vane, and transmitted to the processor of the yawing motor controlcircuit in the form of electrical signals, and a yawing command of clockwise or anticlockwise rotation is sent to the yawing motor by the processor after comparison, therefore, a wind wheel can rapidly and smoothly realize the effect of yawing wind facing.
Description
Technical field
The utility model relates to a kind of wind power generation field, specifically is that wind power generating set is to wind apparatus.
Background technique
Because wind direction changes within the specific limits, and the size of wind-force also changes, when the direction of wind vector changes, obtains the wind energy of maximum in order to make wind wheel, just must go off course to wind to wind wheel.
The model utility content
The purpose of this utility model is to provide a kind of wind power generating set to wind apparatus, and this device can realize that the driftage of wind wheel quick and stable ground is to wind.
The technical scheme in the invention for solving the technical problem is: this wind power generating set is to wind apparatus, it is characterized in that, the sensor wind vane is electrically connected on the processor of yaw motor control loop, described yaw motor connects the driftage plane table thermoconductivity meter, yaw motor is fixed on the engine room foundation, the output gear of driftage plane table thermoconductivity meter is meshed with driftage bearing ring gear, driftage bearing ring gear is fixedlyed connected with the tower tube by tower tube link, and the yaw gear outer ring is fixed on the engine room foundation.
Its working procedure is, the variation of wind vane perception wind direction, and be delivered in the processor of yaw motor control loop with the form of electrical signal, send clockwise or the driftage order that rotates counterclockwise to yaw motor through comparing preprocessor, because yaw motor and engine room foundation are connected as a single entity, carry out the output gear of driftage instruction rear driving driftage plane table thermoconductivity meter when yaw motor, because driftage bearing ring gear is static, thereby make yaw motor with the deflection of engine room foundation edge driftage bearing ring gear, realize wind.
The beneficial effects of the utility model are: because the variation of wind vane perception wind direction, and be delivered in the processor of yaw motor control loop with the form of electrical signal, send clockwise or the driftage order that rotates counterclockwise to yaw motor through comparing preprocessor, thereby can realize that the driftage of wind wheel quick and stable ground is to wind.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 yaw axis bearing outer-ring, 2 floating type brake calipers, 3 cushion blocks, 4 brake discs, 5 engine room foundations, 6 tower tubes, 7 driftage bearing ring gears.
Embodiment
As Fig. 1, wind power generating set comprises parts such as wind vane, yaw motor, driftage plane table thermoconductivity meter, driftage bearing to wind apparatus.
Wind vane is as the sensor of perception wind direction, it is electrically connected on the processor of yaw motor control loop, yaw motor connects the driftage plane table thermoconductivity meter, yaw motor is fixed on the engine room foundation 5, the output gear of driftage plane table thermoconductivity meter is meshed with driftage bearing ring gear 7, driftage bearing ring gear 7 is fixedlyed connected with tower tube 6 by tower tube link 4, and yaw gear outer ring 1 is fixed on the engine room foundation 5.Tower tube link 4 has brake disc, and this brake disc is positioned at the jaw of floating type brake caliper 2, and floating type brake caliper 2 can be implemented braking to brake disc under the hydraulic system effect.
The variation of wind vane perception wind direction, and be delivered in the processor of yaw motor control loop with the form of electrical signal, send clockwise or the driftage order that rotates counterclockwise to yaw motor through comparing preprocessor, because yaw motor and engine room foundation are connected as a single entity, carry out the output gear of driftage instruction rear driving driftage plane table thermoconductivity meter when yaw motor, because driftage bearing ring gear is static, thereby make yaw motor with the deflection of engine room foundation edge driftage bearing ring gear, realize wind.Behind wind, yaw motor quits work, and hydraulic system promotion brake caliper 2 contacts with brake disc during braking state, realizes braking fully.In the wind process, the dynamics that HYDRAULIC CONTROL SYSTEM brake caliper 2 contacts with brake disc is for half braking state, and brake caliper and brake disc produce certain resistance and be used for the extraneous wind-force of balance in the process of slide relative, make the wind process steadily through row.Aforementioned is not to carry out at any time to pneumatic work, but is benchmark with the mean value of wind direction in a period of time.Thereby be discontinuity to pneumatic work.
