The model utility content
The purpose of this utility model provides a kind of simple in structure and can change the Purely mechanical wind-driven generator of regulating spindle speed automatically according to wind-force;
For achieving the above object, the technical solution of the utility model is: a kind of mechanical type rotor wind-driven generator that stretches, comprise main shaft, rotor magnet and staor winding, rotor magnet is installed on the main shaft, rotor magnet places staor winding, be set with wheel hub and lower hub on the described main shaft, the described wheel hub of going up is fixedlyed connected with main shaft, described going up between wheel hub and lower hub is provided with pressure spring, fixedly connected with rotor magnet in the bottom of described lower hub, described going up between wheel hub and lower hub is provided with at least one group of linkage mechanism, described linkage mechanism comprises an end and hinged last connecting rod and an end and the hinged lower link of lower hub of last wheel hub, the described free end of going up connecting rod and lower link is hinged and is in the same place, and described upward connecting rod and lower link are provided with weight in the hinged place.
Preferably, described side of going up wheel hub and lower hub is fixed with at least one engaging lug respectively, and described engaging lug is provided with preformed hole, and linkage mechanism is hinged on the preformed hole of engaging lug; Utilize engaging lug hinged, can make structure more stable, and can more conveniently install with carrying out;
Preferably, described lower hub bottom is fixed with the connecting rod of hollow, and described rotor magnet is fixed on the connecting rod outside, and described connecting rod is sleeved on the main shaft; Adopt connecting rod stationary hub and rotor magnet, the torque that main shaft is rotated is passed to lower hub by connecting rod, when having avoided by the lower link transmitting torque, and the stressed bigger problem of lower link;
Preferably, described linkage mechanism is with respect to the main shaft symmetric arrangement; Adopt the structure of symmetric arrangement, in the time of can balancing out high speed rotating, the additional centrifugal stress that weight produces main shaft on the linkage mechanism.；
The beneficial effects of the utility model are: because last wheel hub is fixedlyed connected with main shaft, lower hub can move axially along main shaft, be hinged with upper and lower connecting rod between upper and lower wheel hub, the free end of upper and lower connecting rod is hinged, and be provided with weight in the hinged place, when utilizing the wind-force conversion, the change of main axis rotation speed, the centrifugal force of weight also correspondingly changes, thereby influence the spacing of upper and lower connecting rod, the cutting area of rotor magnet and staor winding is changed, thereby change the size of the electromagnetic force that blocks rotating shaft and influence main shaft speed, make it maximal efficiency ground and produce electric current.
Embodiment
Below in conjunction with accompanying drawing the flexible rotor wind-driven generator of the utility model mechanical type is elaborated.
As shown in Figure 1, main shaft 1 is for being provided with vaned rotatingshaft, blade can drive main shaft 1 rotation after being subjected to the wind-force effect, last wheel hub 2 suits also are fixed on the main shaft 1, lower hub 8 is sleeved on the main shaft 1, and can move axially along main shaft 1, the top of lower hub 8 is provided with the pressure spring 3 that is sleeved on the main shaft 1, the other end of pressure spring 3 is fixed on the bottom of wheel hub 2, main shaft 1 is provided with two groups of linkage mechanisms, linkage mechanism comprises the engaging lug 4 that is fixed on the wheel hub 2 and lower hub 8 outsides, engaging lug 4 symmetries are fixed on the outside of wheel hub 2 and lower hub 8, the default hinging hole that is equipped with on the engaging lug 4, one end of two last connecting rods 5 all is hinged on the side of wheel hub 2 by the preformed hole on the engaging lug 4, lower hub 8 adopts similar methods to be hinged with two lower links 6 symmetrically, after connecting rod and last wheel hub 2 and lower hub 8 are hinged, the free end of last connecting rod 5 and lower link 6 is hinged, the hinged place of connecting rod 5 and lower link 6 on every group, all be connected with a weight 7, when main shaft 1 rotation, weight 7 is because the centrifugal action expansion, the drivening rod mechanism kinematic, connecting rod 5 and lower link 6 are changed at the angle of its hinged place, because last connecting rod 5 and lower link 6 are rigid pipe, and last wheel hub 2 is fixedlyed connected with main shaft 1, lower hub 2 is driven by lower link 6 and rotates with main shaft 1, simultaneously can be along main shaft translation about in the of 1, pressure spring 3 with reaction force, makes lower hub 8 be in default position for the ascending motion of lower hub 8.Be set with connecting rod 9 on the main shaft 1 of lower hub 8 belows and be fixed on the bottom of lower hub 8, the bottom suit of connecting rod 9 also is fixed with rotor magnet 10, rotor magnet 10 is a hollow cylindrical, coating staor winding 11 around the rotor magnet 10, staor winding 11 is fixed on motor casing or other firmware, the center of staor winding 11 is coaxial with the center of rotor magnet 10, when linkage mechanism is in deployed condition, only some is coated on its inside with rotor magnet 10 to staor winding 11, electromagnetic induction owing to above rotor magnet 10, do not take place with rotor magnet 10 in a part; When linkage mechanism was in rounding state, lower hub 8 rose on the position on the main shaft 1, and rotor magnet 10 almost all is positioned at the coating scope of staor winding 11.
Working principle of the present utility model is:
When wind speed was smaller, during main shaft 1 low speed rotation, the weight 7 of linkage mechanism was in contraction state, and lower hub 8 is positioned at minimum point, had only this moment fraction rotor magnet 10 and staor winding 11 to have an effect, and produced electric current output; When wind speed was big, the weight 7 of linkage mechanism was subjected to centrifugal action bigger, and drivening rod mechanism disperses along the radially outward of main shaft 1, and drove lower hub 8 and move up, and promptly drove on the rotor magnet 10 and moved, and made it to have an effect with multiple stators winding 11 more.
Since in the electromagnetic induction process, the effect that can receive ampere resistance, when main shaft 1 rotating speed increased, rotor magnet 10 also increased with the active area of staor winding 11, and this moment, the ampere resistance increased thereupon, and the rotating speed of main shaft 1 is limited in certain scope.
