Description
Technical field
What the present invention relates to is wind-driven generator, and especially a kind of weak wind be applied on wind-driven generator starts, raises speed and strong wind speed reducer.
Background technique
Wind-power electricity generation, being never exhausted non-polluting renewable clean energy resource, attractes attention in the whole world.On the earth, available wind energy is 2 × 107mw, is 3 times of the energy summation that the annual coal combustion in the whole world obtains, is 10 times of the water energy total amount that can develop.Therefore, the relevant research and development of wind-driven generator are one of key projects of each country.
China territory is vast, and shore line is long, and wind resource enriches, having a high potential of Wind Power Utilization, and the developed installation total capacity of land and wind energy on the sea reaches 7 ~ 1,200,000,000 kw even 2,500,000,000 more than kw.Therefore, wind-powered electricity generation has rich resource base, is the important component part of Chinese future source of energy structure.
Wind-power electricity generation utilizes wind-force effect, air vane is rotated and the process of drive electrical generators rotor rotation generation current, namely the kinetic energy of wind is become mechanical energy, then be electric energy changes mechanical energy, therefore, wind speed is critical problem to wind-power electricity generation, and wind speed is too little, does not promote fan blade rotation, cannot generate electricity, slightly bigger wind speed, fan blade rotating speed is too low again, and generated energy is minimum; But wind-force is too large, wind speed is too fast easily produces stall event again, destroys generator.The current windmill technology of China can only at wind speed 3m/s---could generate electricity between 20m/s, but generated energy is quite faint, well below electric motor power.We know, the transfer power=rotating speed × torque of wind-driven generator, visible wind speed is higher, and generated energy is larger.Therefore, how allowing fan blade obtain higher rotating speed in weak wind, is the emphasis research topic improving effectively acting at full capacity in generator electric motor power.
Summary of the invention
The weak wind that the technical problem to be solved in the present invention is to provide a kind of wind-driven generator starts, raises speed and strong wind speed reducer, can start fan blade and rotate, improve fan blade rotating speed, increasing electricity output when weak wind.
For realizing described object, the technical solution used in the present invention is: the electric generator casing after fan blade is installed increment plate.Specifically on the electric generator casing of fan blade position after a while, symmetrically with chain connection two block incremental plate centered by generator arbor, between increment plate and casing, be also provided with follow block spring.
In the structure that technique scheme provides, when flowing through the wind continuing to move to generator rear after fan blade and being subject to the stop of increment plate, under flattened state, the wooden partition of increment plate radially spreads to surrounding.Because increment plate distance fan blade is nearer, this wind to surrounding diffusion radially will act on fan blade, until arrive the fan blade leaf body within the scope of whole increment board diameter, increase wind and act on lifting surface area on fan blade, define a large amount of effective wind rates, improve generator speed, achieve the technical purpose that the weak wind of the present invention starts speed-raising.
With chain connection between increment plate and casing, between increment plate and casing, also has a follow block spring.Follow block spring is against on increment plate under normal circumstances, spring tension has ensured the flattened state of increment plate, when wind-force is excessive, when exceeding the spring tension of setting, spring is compressed, sweptback space length has been abdicated to increment plate, increment plate is just tilted backwards by vertical flattened state under normal circumstances and forms angle, widen the distance of increment plate and fan blade, allow wind quickly through, wind-force is larger, the power that increment plate leans on backward is larger, angle is also larger, relieve the speed-raising effect of increment plate, release the energy of wind, therefore, follow block spring in fact serves the technique effect of strong wind protection.
Described two block incremental plates entirety under flattened state is circular, square or polygonal, and plate face can be plane or corrugated surface.
The crow flight distance of described increment plate distance fan blade is 15-30cm is good, too far can slacken return air and contact with the effective of fan blade, too closely then have certain potential safety hazard.
Under high wind conditions, because the increment plate after tilting reduces front angle windward, the wind-force be subject to will reduce naturally, therefore, on the limit that the outer rim of increment plate has a bend forward or turns up, be used for increasing the pocket power to wind, form the tension force that enough recoils resist spring, add big blade and the direct angle of increment plate, discharge wind energy further.
Compared with prior art, the wind continued after flowing through fan blade to the motion of generator rear can stop by increment plate provided by the invention, it is forced radially to spread to surrounding along wooden partition, then fan blade is acted on, until arrive the fan blade leaf body within the scope of whole increment board diameter, increase wind and act on lifting surface area on fan blade, define a large amount of effective wind rates, improve generator speed.Simultaneously, follow block spring after increment plate ensure that when increment plate is subject to the active force of high wind, automatically change into from flattened state the heeling condition leaned on backward, wind-force incremental contribution disappears, and fan blade rotating speed slows down, and has ensured the safe operation of wind-driven generator, the invention belongs to mechanical structure, manufacture and maintenance cost low, by force, safety coefficient is high for stability.
Below in conjunction with accompanying drawing, the present invention will be further described.
Accompanying drawing explanation

Fig. 2 is follow block spring attachment positions schematic diagram.
Embodiment
As shown in Figure 1, in the front end of fan blade 1 electric generator casing at about 15 ~ 30cm place after a while, symmetrically centered by generator arbor install two block incremental plates 201 and 202, this increment plate is movably connected on electric generator casing by hinge 9.Structural drawing clearly illustrate when flow through continue to be subject to the stop of increment plate 201,202 to the wind of generator rear motion after three fan blades 1 time, state under flattened state (note: flattened state is the working state of increment plate under weak air quantity and benign air quantity weather conditions)) under the wooden partition of increment plate radially spread to surrounding.Because increment plate 201,202 distance fan blade 1 is nearer, this wind to surrounding diffusion radially will act on fan blade, until arrive the fan blade leaf body within the scope of whole increment board diameter, increase wind and act on lifting surface area on fan blade, define a large amount of effective wind rates, improve generator speed, achieve the technical purpose that the weak wind of the present invention starts speed-raising.
As shown by the downward arrows, under high wind conditions, because the increment plate after tilting reduces front angle windward, the wind-force be subject to will reduce naturally, therefore, on the limit 12 that the outer rim of increment plate has a bend forward or turns up, be used for increasing the pocket power to wind, form the tension force that enough recoils resist spring, add big blade and the direct angle of increment plate, discharge wind energy further.
As shown in Figure 2, follow block spring 1101 and 1102 is also provided with between increment plate and casing.When air quantity is excessive, when the power acted on increment plate is greater than the support tension force of the follow block spring 1101 and 1102 be supported between increment plate and casing, namely increment plate changes flattened state and tilts backwards formation angle by the rotation connecting hinge 9, just relieves the incremental contribution under flattened state.Wind-force is larger, and the power that increment plate leans on backward is larger, and the angle that increment plate and fan blade are formed is also larger, be beneficial to wind quickly through, evaded because strong wind stall causes the too fast machine breakdown caused of generator speed, ensured the safe operation of wind-driven generator.Along with weakening gradually of strong wind air quantity, weak to when being less than the setting tension force of tension spring 1101 and 1102, increment plate will be back into flattened state by spring again, continues the normal working that its increases fan blade effective wind rate.
