Embodiment
For ease of explanation this case represented central idea in foregoing invention content one hurdle, express with specific embodiment.Various different objects are described in the ratio that is suitable for illustrating, size, amount of deformation or displacement amount among the embodiment, but not are drawn in the ratio of actual components, close chat earlier bright.And in the following description, similar elements is to represent with identical numbering.
As Fig. 1 to Fig. 3, description one has the wind-driven generator of this case wind sheltering device.This wind-driven generator comprises a pylon 10, and these pylon 10 top groups are established a cabin 11, and the front end in this cabin 11 is provided with a fan 12.About power facility, the brake system of these 11 inside, cabin, and the annexation of aforementioned both and this fan 12 is known technology, and non-pattern characteristics emphasis do not added to give unnecessary details at this.
Above-mentioned wind sheltering device comprises an aerovane 20, a processor 30 and a steering controller 40.This aerovane 20 is located at the preceding wind-engaging end 111 in this cabin 11, and this processor 30 is fixed on this pylon 10, and is coupled with this aerovane 20.This steering controller 40 and these processor 30 couplings receive this deflection angle signal.This steering controller 40 realizes that with an adopting direct drive motor 42 this motor is fixed in the top of this pylon 10, and this adopting direct drive motor 42 has a live axle 41, and this live axle 41 is connected in this cabin 11, in order to control this cabin 11 rotation predetermined angles.
Above-mentioned aerovane 20 is a known device, roughly has the fuselage 21 of a streamline, and the front end of this fuselage 21 is the wind speed inductor with the propeller cavitation 22 of four leaves, and the rear end is a direction inductor with an empennage 24.This aerovane 20 senses wind speed and wind direction, and wind direction and the wind velocity signal that it produced transferred to this processor 30.This processor 30 receives this wind direction and wind velocity signal, converse the angle that deflection is answered in this cabin 11 with built-in program according to this wind direction and wind velocity signal, and will answer deflection angle to be converted to a deflection angle signal, the signal of this deflection angle transfers to the controller of this adopting direct drive motor 42, start this adopting direct drive motor 42 by this controller again, turn this cabin 11 with its live axle 41 and rotate predetermined angle.
When the plane of rotation 121 of fan 12 is vertical with wind direction (as shown by arrow A), be best wind-engaging angle, as Fig. 4 for fan.When the plane of rotation 121 of fan 12 was parallel with wind direction, this fan promptly can't capture wind energy.Based on this principle, as Fig. 5, if the measured wind speed of this aerovane 20 is greater than survival wind speed, this steering controller 40 is according to the deflection angle signal of this processor 30, control this cabin 11 rotation predetermined angles, make the plane of rotation 121 of this fan 12 be parallel with wind direction (as shown by arrow A), make fan can't capture wind energy, reduce the rotating speed of fan 12 simultaneously, avoid fan 12 because of being subjected to the problem of strong wind stall rotation even fracture, and having alleviated the load of this brake system, the wind load that is subjected to of this pylon 10 also reduces simultaneously, can avoid the danger that causes this pylon 10 to tilt even collapse excessively by force because of wind.
The above description of this invention is illustrative, and nonrestrictive, and those skilled in the art is understood, and can carry out many modifications, variation or equivalence to it within spirit that claim limits and scope, but they will fall within the scope of protection of the present invention all.
