It should be noted that, when the included angle between the wind direction detected by the anemoscope 201 and the central line of the blade adjusting component 3 is greater than 90 °, the controller 301 drives the wind direction adjusting component 2 to rotate along the direction in which the included angle gradually decreases, and in the process of adjusting the included angle from the obtuse angle to the right angle, since the blades 308 are opposite to the wind direction, in order to reduce the wind resistance when the blades 308 rotate, the deflection angle of the blades 308 needs to be at the maximum angle A1, the controller 301 controls the blade adjusting component 3 to adjust the angle of the blades 308 to the position in which the included angle between the wind direction is minimum, so that the resistance when the blades 308 rotate along with the machine body component 1 can be greatly reduced until the included angle between the wind direction and the central line of the blade adjusting component 3 is 90 °, in this process, the blades 308 are always at the position A1, then, the controller 301 continues to control the wind direction adjusting component 2 to rotate, and in the adjusting process of the included angle between the wind direction and the central line of the blade adjusting component 3 from 90 ° to 0 °, in order to achieve the best power generation performance, the controller 301 controls the blade 308 to deflect from the maximum angle A1 to the maximum angle A2 rapidly under the adjustment of the blade adjusting component 3, so that the contact area of the blade 308 and the wind is the largest, and the front face and the wind direction of the blade 308 are opposite, so that the blade 308 can be driven to rotate under the action of the wind force, and the projection area of the blade 308 on the vertical face is the largest, so that the contact area of the wind can be increased, the wind force can be conveniently utilized to be maximized, the blade 308 is driven to rotate under the action of the wind force, and the opposite angle of the blade 308 and the wind direction is bigger, so that the rotation speed of the blade 308 is faster under the driving of the pressurization of the wind force, and the power generation efficiency is higher.
In the adjusting process of the included angle between the wind direction and the central line of the blade adjusting component 3 from 90 degrees to 0 degrees, the wind force borne by the blade 308 is gradually increased, so that the rotating speed of the blade 308 is increased more and more, the rotating speed of the high-speed rotating shaft 103 is multiplied under the speed increasing action of the gear speed increasing box 104, the rotating speed of the high-speed rotating shaft 103 is detected by the rotating speed sensor at any time, a control basis can be provided for the generator 102 to reach the limit rotating speed, when the included angle between the wind direction is adjusted to 0 degree, if the rotating speed of the high-speed rotating shaft 103 does not reach the limit threshold value, wind power generation can be continuously carried out at the right angle and the minimum angle A2 of the blade 308, the optimal generating efficiency can be achieved, and the anemoscope 201 provides an adjusting basis for the right angle between the blade 308 and the wind direction and adjusts the rotating angle of the blade 308 in real time under the control of the controller 301, so that the blade 308 can bear the maximum wind force, and the generating efficiency is improved.
In the process of adjusting the included angle of wind direction from 90 degrees to 0 degrees, the rotating speed sensor detects that the rotating speed of the high-speed rotating shaft 103 reaches the limit threshold value, the situation shows that wind force is large, the controller 301 achieves fixing of the wind direction adjusting component 2 at the position where the rotating speed of the high-speed rotating shaft 103 reaches the limit threshold value, namely, the electric push rod 210 is controlled to act, the electromagnet 208 and the limit ring 211 are enabled to conduct magnetic attraction fixing, at the moment, the generating efficiency of the generator 102 can be guaranteed, because an included angle exists between the machine body component 1 and the wind direction, wind force generates rotating moment for the wind direction adjusting component 2, at the moment, the controller 301 controls current in the electromagnet 208 at one side of the wind direction to increase, so that the magnetic attraction degree between the electromagnet 208 and the limit ring 211 at the side can be increased, the rotating moment received by the wind direction adjusting component 2 can be offset under strong wind force, meanwhile, the fixed limit between the limit ring 211 and the electromagnet 208 can be achieved by utilizing the magnetic attraction between the electromagnet 208 and the limit ring 211, and the angle locking of the machine body component 1 can be achieved.
It should be noted that when the rotation speed of the high-speed rotation shaft 103 reaches the limit threshold, the larger the included angle between the machine body assembly 1 and the wind direction is, the larger the wind force is, the larger the rotation moment received by the wind direction adjusting assembly 2 is under the action of the wind force, so that the controller 301 can increase the current value in the electromagnet 208 on one side of the wind direction according to the included angle between the machine body assembly 1 and the wind direction, and the stability degree of the wind direction adjusting assembly 2 when being locked can be realized according to the wind force, so that the situation that the wind direction adjusting assembly 2 is deviated due to the wind force after the angle adjustment is completed is prevented.
It should be noted that, when the wind direction detected by the anemoscope 201 is exactly opposite to the blade 308, the controller 301 does not need to control the wind direction adjusting assembly 2 to act, and only controls the deflection angle of the blade 308 through the blade adjusting assembly 3 to maximize the power generation efficiency, that is, under the detection of the rotation speed sensor, the controller 301 controls the blade adjusting assembly 3 to act to adjust the deflection angle of the blade 308, so as to maximize the projection area of the blade 308 on the vertical plane, thereby increasing the contact area of wind and facilitating the maximization of wind power utilization, that is, the deflection angle of the blade 308 is gradually reduced from A2 to A1 until the rotation speed detected by the rotation speed sensor reaches the limit threshold.
It should be noted that, because wind force is indefinite, although the surface of the blade 308 is arc-shaped, so that impact rotation is conveniently realized under the action of wind force, based on the radian value on the blade 308, the rotation angle of the blade 308 with optimal efficiency under the action of wind force is corresponding to the wind force, so that the deflection angle of the blade 308 is related to the magnitude of wind force, for example, the radian of the blade 308 is C0, the blowing wind speed under the maximum efficiency is D, at this time, under the blowing of D, the rotation speed of the blade 308 is the maximum, when the angle of the blade 308 is increased or decreased, the rotation speed of the blade 308 is reduced, and based on the working principle, the deflection angle of the blade 308 is adjusted through the blade adjusting assembly 3 during the rotation of the blade 308 when the wind direction is positive, so that the rotation speed can be detected all the time through the rotation speed sensor during the deflection angle adjustment of the blade 308 until the rotation speed of the blade 308 is detected to be the maximum, and the controller controls the blade adjusting assembly 3 to stop working, so that the optimal deflection angle of the blade 308 can be realized.
However, when the rotation speed detected by the rotation speed sensor reaches the limit threshold, at this time, for safety reasons, the controller 301 controls the brake protection assembly 4 to act, increases the load when the blades 308 rotate to reduce the rotation speed of the high-speed rotation shaft 103, and does not recover within the normal threshold range when the rotation speed of the high-speed rotation shaft 103 is within a short time, at this time, the controller 301 controls the blade adjustment assembly 3 to act to increase the deflection angle of the blades 308, so that the rotation speed of the high-speed rotation shaft 103 can be further reduced, the safety is improved, and at the same time, when the rotation speed value detected by the rotation speed sensor suddenly increases, the controller 301 also correspondingly increases the current value in the electromagnet 208 at one side of the wind direction according to the increase amplitude of the rotation speed to ensure the stability degree of the wind direction adjustment assembly 2 after the position is fixed, and increases the anti-rotation moment of the wind direction adjustment assembly 2.
Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present application, and although the present application has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present application.
