Description
Technical field
The utility model belongs to generator protection technical field, is specifically related to a kind of Anti-Typhoon wind power generation blade.
Background technique
Compared to nuclear energy power generation, the existing security concerns of the mode such as thermal power generation and hydroelectric power and environmental issue, wind-power electricity generation is undoubtedly a kind of better selection of anxiety safer and not welding, especially because nuclear energy, the demand of thermal power generation and a large amount of recover petroleum, combustion gas, the natural resourcess such as colliery, not only cause the effect that warms up of the destruction of physical environment and the earth, more face problem of energy crisis, to be to come into one's own gradually with green energy resources such as wind energies, become the target of advanced country's active development researchs such as America and Europe, the mode of vane drive but existing wind-driven generator mainly adopts, although adopt overall blade, it can solve driving problems, but it is in the time suffering high wind, because stress surface is large, make blade accelerate rotation, cause generator overload or blade broken, a kind of generation device of renewable energy sources is disclosed in CN 1648445 A, particularly relate to the Anti-Typhoon wind-driven generator of a kind of energy.The object of wood invention is to realize like this; the some axles that can rotate are set on the supporting frame of windmill; and be provided with clockwork spring and small-sized windmill in the upper end of axle; in the time that wind-force is large; the small-sized Windmill rotary of wind blows; and make roller rotate the sail shrinking around on axle; thereby reach the thrust that reduces Wind power propelling windmill; the Anti-Typhoon ability of protection wind-driven generator; although it can resist typhoon; but it can not be crossed and guarantee the integrity of small-sized air vane, therefore need a kind of can be in the situation that intensity exceedes wind speed setting the blade of artomatically folded.
Model utility content
The purpose of this utility model is to provide a kind of simple in structure, easy and simple to handle and blade that can artomatically folded.
To achieve these goals, the scheme adopting is: a kind of Anti-Typhoon wind power generation blade, comprise blade, described blade is divided into leaf bar and leaf fan, described leaf bar and leaf fan pass are crossed and are hinged, described leaf bar is crossed electromagnet with leaf fan pass and is connected, and described leaf bar and leaf fan rear portion arrange forced locking device, on described leaf bar, air velocity transducer are set.
Described forced locking device comprises dead bolt and snap close, and described dead bolt is " ↑ " shape, and described snap close is " V " shape electromagnetic clamp coordinating with it.
Described leaf bar and leaf fan are carbon fiber composite product.
Described electromagnet is connected with accumulate pond by induction switch.
Described induction switch is connected with air velocity transducer.
The utility model adopts foldable type blade to make it to carry out power-off voluntarily in the control by air velocity transducer, make it can be under the inertia of air speed influence, dead bolt is connected with snap close, auto lock, reduce the blowing area of blade, make blade not rotate too fast or not turn, less blowing area has improved the chances of survival of blade under high wind condition; Be controlled at by sensor that under the condition that exceeds certain wind speed, it can disconnect the power supply of electromagnet voluntarily, leaf fan is separated with leaf bar, and under wind action, the locking of dead bolt and snap close now, while itself and V-arrangement electromagnetic clamp being locked due to the snap close of employing ↑ shape, the mode that it can be combined with V-arrangement sidewall by the card on both sides, has guaranteed fixing intensity; Adopt carbon fiber composite product to guarantee its structural strength, make it can resist high wind; After high wind disconnects electromagnetic clamp power supply, it can be opened electromagnetic clamp, make leaf fan separate with leaf bar later, and be attached together by the effect of electromagnet, form complete blade; The utility model is simple in structure, easy and simple to handle, is worthy to be popularized and applies.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the folding structural representation of the utility model.
Embodiment
As depicted in figs. 1 and 2: a kind of Anti-Typhoon wind power generation blade, comprise blade, described blade is divided into leaf bar 7 and leaf fan 1, described leaf bar 7 and leaf fan 1 are by being hinged, described leaf bar 7 is connected by electromagnet 8 with leaf fan 1, described leaf bar 7 and leaf are fanned 1 rear portion forced locking device are set, and on described leaf bar 7, air velocity transducer 9 are set.
Described forced locking device comprises dead bolt 2 and snap close 3, and described dead bolt 2 is " ↑ " shape, and described snap close 3 is " V " shape electromagnetic clamp coordinating with dead bolt.
Described forced locking device is connected with accumulate pond 6 by induction switch B4, and described induction switch B4 is connected with air velocity transducer 9.
Described leaf bar 7 and leaf fan 1 are carbon fiber composite product.
Described electromagnet 8 is connected with accumulate pond 6 by induction switch 5.
Described induction switch 5 is connected with air velocity transducer 9.
The utility model is in the time meeting with high wind, by air velocity transducer, signal is passed to induction switch, in the time exceeding the numerical value that induction switch sets, it can automatic cut-off power, leaf fan is separated with leaf bar joining part, and under wind action, leaf is fanned around merging backward with the hinged place of leaf bar, by the effect of wind-force, leaf bar is combined with the dead bolt that leaf fan back arranges with snap close, guaranteed its firmly combination; While itself and V-arrangement electromagnetic clamp being locked due to the snap close of employing ↑ shape, the mode that it can be combined with V-arrangement sidewall by the card on both sides, guarantee fixing intensity, made also can not cause dead bolt to separate with snap close in electric situation, further guaranteed the intensity of combination; Later by air velocity transducer, signal is passed to induction switch B at high wind and make its deenergization, leaf fan is separated with leaf bar, in the time rotating to bottom, leaf fan is combined with leaf bar, thereby makes it revert to an overall blade.
