Description
Technical field
The utility model relates to a kind of wind generating unit, particularly a kind of wind-driven generator that has engaging and disengaging gear
Background technique
Existing windmill electric generating apparatus, its blade mostly is propeller form, and owing to structural reason generally is directed the installation, promptly level is installed.The startup wind speed of this windmill electric generating apparatus is usually more than 2m/s, under the wind speed about 1m/s, when particularly the wind direction change frequency is higher, very low to utilization ratio of wind energy, and bringing onto load starts and to be difficult to proper functioning basically, and this makes that Wind Power Utilization and technology are promoted in the generating of small-power windmill and is subjected to certain restriction.In addition, for the situation that prevents to meet with high wind the generator overload that may cause and damage the situation of generator, existing windmill electric generating apparatus all adopts intelligentized control device, and the cost of this mode is the significantly increase that has caused the electricity generating device cost.Therefore be necessary the windmill electric generating apparatus that is limited to is improved.
Summary of the invention
The purpose of this utility model just is to overcome the existing existing above-mentioned defective of windmill electric generating apparatus, thereby provide a kind of wind-driven generator of new band centrifugal clutch, adopt pure mechanical mode just can overcome the shortcoming that forceful electric power damages, and simple and practical, with low cost.
For achieving the above object, the utility model is achieved in that
A kind of wind-driven generator with centrifugal clutch, comprise rotating shaft, several blades that link to each other with rotating shaft by connecting rod, the driving mechanism that the rotating shaft below connects, and the generator that is connected with this driving mechanism, it is characterized in that this driving mechanism comprises a case, be provided with a rotating shaft and a pair of clutch mechanism in the case; This clutch mechanism directly is connected with generator, with the rotating shaft mating reaction.
Be provided with the bar that is slidingly connected in described this rotating shaft, rotating shaft is to being provided with the clutch track to clutch junction, to be used to limit the zone that slides up and down of bar of being slidingly connected: the middle part of this bar that is slidingly connected is provided with the connection platform, and in this rotating shaft, connect platform and have a contact block, when connecting platform, can contact with this contact block to lower slider.
This clutch mechanism is by support, and the centrifugal moving of hook lower end colluded and be fixed in clutch; Its bending place is fixed on the inner set fulcrum of case, and insert in the clutch track upper end that this clutch is colluded, and the lower end then connects centrifugal.
Like this, when windmill rotated under wind energy drives, case and internal component thereof also rotated along with rotating shaft, and centrifugal is moved to outer rim under action of centrifugal force at this moment, the upper end that drives D score shape part presses down straight pin, and then drives the elastic force that the bar that is slidingly connected overcomes spring and move down; When wind speed reaches certain intensity, the connection platform of the bar that is slidingly connected contacts with described contact block, and then drives generator for electricity generation; And when wind speed was too fast, the bar that is slidingly connected continued to move down, and it connects platform and breaks away from and the contacting of contact block thereupon, thereby can effectively avoid the generator overload and damage.
In addition, generator of the present utility model, the cross section of its blade are the swallow aerofoil profile, and this improvement can make windmill also can realize non-loaded startup under the wind speed about 1m/s, thereby have guaranteed the normal operation of windmill.
Windmill electric generating apparatus of the present utility model can be realized the non-loaded startup of windmill, and need not complicated intelligent control device, can guarantee the normal operation of electricity generating device, and is not only simple and practical, and greatly reduces cost.
Description of drawings
Fig. 1 is the structural representation of blade of the present utility model and driving mechanism part.
Fig. 2 is the phantom of driving mechanism of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, windmill electric generating apparatus of the present utility model is described in further detail with specific embodiment.Should be understood that following examples only are used to the utility model is described but not are used to limit scope of the present utility model.
As shown in Figure 1, windmill electric generating apparatus of the present utility model comprises rotating shaft 10, by several blades 12 that blade connecting rod 11 links to each other with rotating shaft 30, and the driving mechanism 20 that rotating shaft 10 belows connect, and the generator that is connected with this driving mechanism 20 (figure does not show).According to the utility model, the quantity of described blade 12 is 5.
As shown in Figure 2, this driving mechanism 20 comprises a case 21, rotating shaft 30 and a pair of clutch mechanism 40 are arranged in the case 21, wherein be provided with cavity 31 in this rotating shaft 30, ccontaining one bar 32 that is slidingly connected that can slide up and down in the cavity 31, this lower end that is slidingly connected bar 32 is provided with a spring 33, go up and 30 pairs of this rotating shafts should be provided with a pair of clutch track 301 in the position, to be used to limit the zone that slides up and down of bar 32 of being slidingly connected: this interruption that is slidingly connected bar 32 is provided with the connection platform 321 of one section suitable length, the external diameter of this connection platform 321 is bigger: and the position that is lower than this connection platform 321 in this rotating shaft 30 is provided with a contact block 302, when the bar 32 that is slidingly connected during to lower slider, it connects platform 321 and can contact with this contact block 302: these clutch mechanism 40 clutches collude 41 be fixed on centrifugal 35 of hook lower end; Its bending place is fixed on the inner set fulcrum of case, and insert in the clutch track upper end that this clutch is colluded, and the lower end then connects centrifugal.
Like this, when windmill rotates under wind energy drives, case 21 and internal component thereof also rotate along with rotating shaft 10, move to outer rim under action of centrifugal force centrifugal 35 of at this moment, and clutch is colluded the upper end and then driven the elastic force that the bar 32 that is slidingly connected overcomes spring 33 and moves down; When wind speed reaches certain intensity, the connection platform 321 of bar 32 of being slidingly connected contacts with described contact block 302, and then drive generator for electricity generation: and when wind speed is too fast, the bar 32 that is slidingly connected continues to move down, it connects platform 321 and breaks away from again and the contacting of contact block 302 thereupon, thereby can effectively avoid generator to transship and damage.
