Abstract
The invention relates to a wind driven generator with movable blades. The wind driven generator belongs to wind motors F03D according to an IPC. In order to avoid damage of typhoons to the wind driven generator, movable devices are arranged on a main blade and can cope with damage of typhoons to a unit immediately, the windward angle of each blade can be automatically immediately according to the magnitude of wind, accordingly, electricity can be still generated with small wind after a variable-pitched device and a variable-pitched control device are omitted, and the wind driven generator becomes a low-wind-speed electric generator in the true sense. The problems that wind in a hinterland is small and electricity generation efficiency is low are solved, when the wind speed is larger than 2 m/s, electricity can be generated, the wind driven generation efficiency is improved to more than 60% from about 30%, the comprehensive investment cost is 30% lower than that of thermal power, and wind driven generation is made to have strong market competitiveness.
Description
Technical field
The present invention relates to a kind of wind-driven generator with moving paddle of wind-power electricity generation, divides belong to wind motor F03D according to International Patent Classification (IPC) (IPC).
Background technique
Typhoon is the principal element threatening wind-power electricity generation safety, the wind speed of violent typhoon is more than 25 meters per second, the annual mean wind speed on interior ground is about 4 meters per second, this brings very large difficulty with regard to giving the design of wind power generator oar blade, should can not blow by typhoon, little wind energy power again, both get both at difficulty, just safety can only be placed above the other things, thus blade is caused to become not only thin but also long, moreover also to meet the continuous increase of generator power, blade constantly lengthens, this brings inconvenience just to production and transport, particularly because blade lengthens, cause pylon more and more higher, unit is more and more heavier, unit center of gravity is also more and more higher, safety problem is also more and more serious.Although had vane change device and electric control equipment, becoming oar speed has been 10 degree per second, 9 seconds ability featherings, and typhoon just can destroy unit at 0.1 second.How just can avoid the destruction of typhoon, cause collapse accident, cause damage to investor, the Designers in the whole world are using one's brains to try every possible means.
Summary of the invention
Object of the present invention aims to provide a kind of wind-driven generator with moving paddle.
To achieve these goals, the present invention has installed head on main blade, the destruction of typhoon to wind-driven generator can be tackled instantaneously, also electrical control can not needed automatically to adjust the Windward angle of blade instantaneously according to the size of wind-force, serve the effect becoming oar, therefore can cancel vane change device and electric control equipment, reduce cost of production.Owing to being provided with the function tackling typhoon instantaneously, so blade area can do very large, little wind also can generate electricity, really become low wind speed generator, the problem that in solving, wind little cost of electricity-generating in ground is low, solves electric power layout unbalanced, the problem that long-distance transport loss is large.Originally blade is elongated, and present blade area increases, and can obtain best moment, when wind speed can generate electricity at more than 2 meters per second, make the efficiency of wind-power electricity generation bring up to more than 60% from about 30%.Blade area (mainly leaf tip) can increase and is twice above, and moment can increase by more than five times, can increase the generated energy of more than two times, comprehensive method of investment cost is lower than thermoelectricity 30%, make wind-power electricity generation have very strong competitive capacity, only have superseded thermal power generation, water clear sky indigo plant could realize.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention are described further:
See from Fig. 1, wind wheel 1 is equipped with main blade 2, and the present invention is equipped with head 3 on main blade 2, at moving paddle 4 built with shell fragment 5.
Can see around main blade 2 from Fig. 2 and quiet slide plate 9, dynamic slide plate 10 have been installed, between quiet slide plate 9 and dynamic slide plate 10, lubricating fitting 11 has been installed.Moving paddle 4 is embraced by anchor ear 12, fixes with sieve bolt 13.All component materials can adopt metallic material also can adopt carbon fiber or other composite material.When adopting carbon fiber or other composite material, quiet slide plate 9 is exactly main blade 2, and dynamic slide plate 10 is exactly moving paddle 4.
See from Fig. 3, main blade 2 has installed moving paddle 4.Shell fragment 5, extension spring 6, pull bar 7 have been installed in moving paddle 4.When moving paddle 4 rotation large because of wind, stage clip 8 is compressed, and in order to avoid shell fragment 5 is aging, has installed controlling device 9 at the end of stage clip 8.
See the second enforcement case of the present invention from Fig. 4, main blade 2 has been installed moving paddle 4 and dynamic slide plate 10(only has lower half portion).Shell fragment 5(has been installed in the periphery of moving paddle 4 and dynamic slide plate 10 or has claimed spring), in the periphery of shell fragment 5, anchor ear 12 has been installed, and fixing with sieve bolt 13.At main blade 2 and moving paddle 4, move between slide plate 10 and lubricating fitting 11 has been installed.
