Abstract
The utility model relates to a control device for increasing the starting performance of a wind turbine, belonging to the field of the wind turbine. Vanes of the device are articulated on a hub to form a wind wheel system and a slider connecting rod mechanism which is used for controlling a propeller distance; and the slider connecting rod mechanism and a starting spring are arranged on a rotating shaft of a generator. The control device runs when paddles are in a best angle-of-attack state before the wind turbine is started so that the starting wind speed of the wind turbine is reduced to 2.5m-3m from the original wind speed of 3.5m-4m; and the control device enables the utilization ratio of the wind energy not to be affected when the wind turbine is in a normal wind speed, is used in districts with the annual average wind speed of 6m/s and can increase the energy output by about 15%-20%.
Description
Affiliated technical field
The utility model patent is a kind of control gear from net type raising wind energy conversion system starting performance, belongs to the wind energy conversion system field.
Background technique
On net type wind-driven generator, generally all adopt the lift-type blade to become oar at present.The angle of attack size of lift-type blade is directly related with the wind energy utilization of blade.Angle of attack large starting moment is big, is convenient to starting, but inefficiency, power coefficient is little.Adopt the best angle of attack, though the operational efficiency height, the wind energy conversion system starting difficulty, incision wind speed height, wind energy effectively utilizes hour number few.
Summary of the invention
In order to overcome present small wind turbine starting difficulty, improve the starting performance of small wind turbine, a kind of new raising wind energy conversion system starting performance control gear of the special proposition of the utility model patent.
The utility model patent improves wind energy conversion system starting performance control gear and mainly is made up of locknut, wheel hub, blade, primer spring, linkage mechanism, motor turning axle etc.Its structure is that blade is hinged on the sliding-block linkage that forms wind wheel system and control pitch on the wheel hub, and this mechanism and primer spring are contained on the turning axle of generator.
The working procedure of this raising wind energy conversion system starting performance control gear is: wind mill wind wheel is under the effect of primer spring, when wind speed is lower than starting wind velocity, the wind wheel reach, blade has been realized the big angle of attack under the effect of connecting rod, make the working state of blade become resistance type from lift-type, improve starting torque, be convenient to the wind energy conversion system starting.After the starting, under the effect of the whole blast of wind wheel, move behind the primer spring, blade is in the angle of attack of normal the best, carries out the lift operation, has improved the wind energy utilization of wind wheel.The working pressure of wind wheel when the thrust of its primer spring is started smaller or equal to wind wheel.
This raising wind energy conversion system starting performance control gear is in best angle of attack state operation at wind energy conversion system prestart blade, makes the wind energy conversion system starting wind velocity be reduced to 2.5m-3m by original 3.5m-4m; This control gear makes wind energy conversion system wind energy utilization in the proper functioning wind speed unaffected, uses in the area of annual mean 6m/s, can improve the about 15%-20% of energy output.
Description of drawings: Fig. 1 is the work schematic representation of this wind energy conversion system starting performance control dress.
Embodiment: embodiment's (see figure 1)
Patent wind energy conversion system starting performance control gear of the present invention mainly is made up of locknut 1, wheel hub 2, blade 3, primer spring 4, linkage mechanism 5, motor turning axle 6 etc.; Blade 3 is hinged on the sliding-block linkage that forms wind wheel system and control pitch on the wheel hub 2.Linkage mechanism 5 and primer spring 4 are contained on the turning axle 6 of generator.
