Abstract
The utility model relates to a sensor setting structure, in particular to a propeller-changing sensor setting structure of a wind driven generator. The propeller-changing sensor setting structure of the wind driven generator comprises a sensor; the sensor is a pressure sensor; a blade root section is arranged at one end of the pressure sensor, and the other end of the pressure sensor is arranged in a propeller-changing bearing. The benefits of the structure are as follows: the propeller-changing angle and the propeller-changing rate are adjusted not through sensing the wind-speed change, but through the root section torque generated by sensing wind acting on the blade. The corresponding torque under different wind speeds has uniqueness, therefore, the adjusting strategy is similar to a wind-speed adjusting strategy, and the system does not need large adjustment. The structure does not need to detect the wind per se but detect the effect, can directly and rapidly sense any change of the wind speed on the sweeping plane, thereby providing more-reliable basis for propeller-changing.
Description
Technical field
The utility model relates to a kind of sensor structure is set, and relates in particular to a kind of wind-driven generator pitching sensor structure is set.
Background technique
Present wind-driven generator pitching all is to decide angle that becomes oar and the speed that becomes oar according to change of wind velocity.Because air velocity transducer is positioned at nacelle top, what experience is hub height place change of wind velocity, for the major diameter wind wheel, any locates change of wind velocity can not reflect whole swept area change of wind velocity situation fully, can not reach consistent so become the oar strategy with change of wind velocity.This will be higher than the big wind speed district of rated wind speed at wind speed, owing to become oar loss not in place and energy-producing.
The model utility content
Provide a kind of wind-driven generator pitching sensor that structure is set in order to address the above problem the utility model, purpose is that the induction wind speed is scanning any variation on plane, thereby provides more reliable foundation for becoming oar.
For reaching above-mentioned purpose the utility model wind-driven generator pitching sensor structure is set, comprises sensor, wherein sensor is a pressure transducer, and an end of pressure transducer is located at the blade root segment, and the other end of pressure transducer is located in the pitch variable bearings.
Described pressure transducer links to each other by the pre-buried swivel nut of screw thread and blade root segment.
The other end of described pressure transducer is located in the bolt hole of ring in the pitch variable bearings.
The utility model has the advantages of: the utility model is no longer regulated by the perception change of wind velocity and is become the vane angle degree and become oar speed, regulates but act on the root segment moment of torsion that blade produces by perception wind.Because moment of torsion corresponding under different wind speed has uniqueness, velocity modulation joint strategy is similar so the adjusting strategy follows the wind, and does not need system is carried out big adjustment.This structure is not to detect wind itself, but detects the effect of its effect, can more directly respond to wind speed more rapidly and scan any variation on plane, thereby provide more reliable foundation for becoming oar.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, pressure transducer; 2, ring in the pitch variable bearings; 3, blade root segment; 4, swivel nut.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model wind-driven generator pitching sensor is provided with structure as shown in the figure, comprise sensor, wherein sensor is a pressure transducer 1, one end of pressure transducer 1 is located at blade root segment 3, the other end of pressure transducer 1 is located in the pitch variable bearings, pressure transducer links to each other by screw thread and blade root segment 3 pre-buried swivel nuts 4, the other end of pressure transducer 1 is located in the bolt hole of ring 2 in the pitch variable bearings, form appropriate drive fit, when being subjected to torsional interaction to experience blade to the formed pressure of bolt surface of contact.By the variation of pressure, signal is passed to the ACTIVE CONTROL system, after the calculating through certain control strategy, will become the oar signal and pass to change oar actuator and move.
This becomes oar mode need set up wind speed and changes between rated wind speed and cut-out wind speed the time because the corresponding relation of the pressure that moment of torsion produced and change vane angle degree and speed.When force value surpassed the rated pressure value, pitch-controlled system was started working, and regulated propeller pitch angle; When force value surpassed critical value, pitch-controlled system began all-cis oar operation.The lead-in wire of pressure transducer 1 can link to each other with master control system in the cabin by the low-pressure shaft center hole with the defeated return tube of variable pitch speed reducer or hydraulic system.
