Summary of the invention
Realize following the tracks of in order to adopt to detect in real time to wind direction with control electric powered steering driving mechanism, the utility model provides a kind of 50KW non-gear box that is incorporated into the power networks directly to drive the variable pitch type wind driven generator group, comprise generator, blade group and wheel hub composition, described blade group is arranged on the described wheel hub by a running shaft, it is characterized in that, described generator set further comprises: wind wheel synchronous variable-pitch mechanism is arranged on described wheel hub rear side; The feather drive system is arranged on the rear end of described generator.
Reasonable is that described generator set further comprises: yaw system is arranged on the lower end of described Variable Pitch drive system.
The utility model adopts and detects wind speed, rotating speed in real time, controls electronic synchronous variable-pitch mechanical chain structure, and ceiling capacity is pounced on and obtained wind energy, and annual electricity generating capacity improves 10%-50%.
Description of drawings
Below, with reference to accompanying drawing, for those skilled in the art that, to the detailed description of the present utility model, above-mentioned and other purposes of the present utility model, feature and advantage will be apparent.
Fig. 1 is an overall structure schematic representation of the present utility model;
Fig. 2 is the broken section structural drawing of Fig. 1.
Embodiment
50KW of the present utility model is that wind energy is converted to electric energy from net, the dual-purpose non-gear box direct-drive aerogenerator group that is incorporated into the power networks, utilize the equipment of generating electricity by natural energy, just as the water generating water, thermal power generation is the same with coal, and used for wind power generation is that unit adopts microcomputer-based intelligent to control automatically in the generating working procedure with the wind generating, wind-driven generator is the uninterruptable power generation operation under 3～25m/s wind speed, rated wind speed is 11m/s, and rated power is 50kW, and maximum output is 60kW.
See also shown in the accompanying drawing 1, the 50KW of the present utility model non-gear box that is incorporated into the power networks directly drives the variable pitch type wind driven generator group and belongs to little series model.Form by a generator set machine one blade group, this vane group comprises a running shaft 28, these running shaft 28 rotating tower tube 20 ends that are fixed on wheel hub 22 rear portions, and the blade 21 in the legend is three, in order to drive generator set (in not shown, referring among Fig. 2 24) running.
Fig. 2 has illustrated the side sectional structure of wind power generating set of the present utility model, can see from this angle, wherein blade 21 is fixed on the wheel hub 22, this blade 21 evenly is installed on the wheel hub 22 by running shaft 28, this blade 21 employing NACA44 * * aerofoil profile, blade of variable cross-section, the glass fibre reinforced plastics composite resin material is made, the efficient height, the life-span is long, and established angle is adjustable.This wheel hub 22 adopts ball-type steel structure, intensity height, light weight.At wheel hub 22 1 ends of this running shaft 28, be provided with synchronous Variable Pitch mechanism 23, this pulp distance varying mechanism 23 adopts three blades in the synchronous Variable Pitch of 120 degree, and the control rotating speed moves at operation interval, avoids overspeed, improves annual electricity generating capacity simultaneously.
Wherein, blade 21 adopts the variable cross section aerofoil profile, the GFRP made, and the efficient height, the life-span is long, and the established angle of blade 21 can be adjusted according to different regions.And electronic synchronous variable-pitch design is adopted in the power adjustment, and blade 21 angle down with the wind changes 0～90 ° with change of wind velocity, and optimization is pounced on and obtained wind energy, improves annual electricity generating capacity.
The utility model has also added a Variable Pitch drive system 25 and a yaw system 26, and the former is arranged on the rear end of magneto alternator 24, and the latter is arranged on the lower end of magneto alternator 24.This wind wheel yaw system 26 adopts the tracking wind vane to control automatically, can follow the tracks of prevailing wind direction all the time, makes the maximum input of wind energy wind wheel.
In addition, generator set of the present utility model is a magneto alternator 24, and the advantage of magneto is not need electric excitation, can realize non-brushing, no excitation loss, thereby efficient height.Cut speedup box and mechanical transmission spindle unit, reduced mechanical failure and equipment noise, had the wind resource area to apply any.Owing to deducted speedup box, the transmission shaft parts, it is low to start wind speed, do not have leakage of oil with because of the different axle center of main shaft cause oscillation phenomenon, reduced failure rate of machinery, improved unit efficiency and reliability.The output cable of this generator set adopts antiwind protector, prevents that cable from twisting off.Also can adopt slip ring to make up 27 transition, avoid turning round cable, more reliable.
