Abstract

The present invention provides an active windmill structure, which is to configure a plurality of blade sets on the periphery of a pivotally rotatable transmission base to be distributed to be separated from each other by a corresponding angle and capable of being rotated to be opened or closed by the ratio of their weights or by electric control. Each of the blade sets is respectively configured with at least one blade disposed at two sides of the transmission base. The blades located at the two sides of the transmission base are perpendicular to each other for extension and are pivotally rotatable synchronously toward the same direction. When the wind comes from the front, one blade set in the horizontal axis is automatically opened in the horizontal direction to minimize the wind resistance. When the wind comes from the rear, the other corresponding blade set in the horizontal axis is automatically closed in the vertical direction to maximize the wind resistance. The blades may generate the pushing force in the rotating direction to rotate a power generator for power generation. For various wind directions, each of the blade sets is capable of actively adjusting the connection of the blades to be perpendicular to each other or have a horizontal angle, so as to form the best wind receiving state for always generating a force difference at two corresponding sides of the transmission base at any time and by any wind direction. The force difference is utilized to continuously rotate the transmission base, so as to achieve the purpose of power generation with most efficient power conversion and output.

Figure 10 is a partial structural view showing a third embodiment of the present invention.

Referring to Figures 1 and 2, it can be seen that the structure of the first embodiment of the present invention includes: a transmission base 1, a blade set 2, 3, and the like, wherein the transmission base 1 can be vertically erected on a base 10. In a possible embodiment, the transmission base 1 can be coupled to a transmission shaft 11 , and the transmission shaft 11 can extend into the base 10 and be coupled to a generator 12 , and between the transmission base 1 and the transmission shaft 11 . There is a bearing 111 that can reduce friction.

The blade sets 2, 3 have the same structure and are disposed at the same angular interval on the periphery of the transmission base 1; in the embodiment, the blade sets 2, 3 respectively have a drive transversely extending through the transmission base 1. The shafts 21, 31, and the drive shafts 21, 31 are arranged perpendicular to each other, and at each end of the drive shaft 21 are provided a blade 22, 23 of the same shape and extending perpendicularly to each other, the blades 22, 23 being eccentric Coupling at both ends of the drive shaft 21, at each end of the drive shaft 31 are provided a blade 32, 33 of the same shape and extending perpendicularly to each other, the blades 32, 33 being eccentrically coupled to the drive The shaft 31 has two end portions, and bearings 13 and 14 for reducing friction are respectively disposed between the transmission base 1 and the drive shafts 21 and 31.

In a possible embodiment, the vanes 32 (or vanes 33) extend toward the vanes 22, 23 (optimally inclined at 45 degrees); and the transmission base 1 is axially A plurality of levers 24, 34 are respectively disposed on the side of the drive shafts 21, 31, and the respective levers 24, 34 can block the blades 22, 23, 32, 33 from being held along the axial direction of the transmission base 1; The shape of 22, 23, 32, 33 can be square, rectangular, 橹, or elliptical, etc., in order to meet different design requirements.

In a possible embodiment, if the center of the drive shaft 31 is centered, and the center has a longer distance a on one side of the blade 33, the center to the other opposite side of the blade 33 has a larger For short distance b, it is better to design eccentricity with a:b=4:1~3:1, so that the longer distance a of the leaf surface 33 produces a horizontal axial self-weight ratio (ie: self-weight ratio), which helps When the blade 33 is subjected to wind, the horizontal axial rotation angle is more easily and rapidly rotated to the vertical direction of the ground due to the weight relationship, thereby exerting a better wind resistance difference; similarly, the blades 22, 23 and 32 also have The same structural features.

Referring to Figures 3 to 7, it can be seen that in the practical application of the first embodiment of the present invention, when the wind direction A acts, the blades 22, 32, 33 have the minimum wind receiving area (i.e., the force of the minimum wind force). The blade 23 is subjected to a wind force (blocked by the bar 24) to assume a state perpendicular to the ground to produce an optimum windward area (i.e., a difference in force of the maximum wind resistance). At this time, the axis of the drive shaft 21 is The far side first side 231 faces downward, and the second side 232 which is closer to the axial center of the drive shaft 21 faces upward (as shown in Fig. 3).

Then, the wind-driven blade 23 drives the transmission base 1 to rotate in the B direction, and when the blade 23 is rotated to a position parallel to the wind direction A (the difference in the force of the minimum wind receiving area), the aforementioned blade 22 is simultaneously parallel with the wind direction A. At this time, the blades 23 are driven by the blades 22 to rotate the first and second sides 231, 232 in the C direction and form a balance (as shown in Fig. 4).

When the inertia of the transmission base 1 continues to rotate, the blade 22 is forced by the wind direction A to be perpendicular to the ground direction, and the other blade 23 is continuously rotated in the D direction to the horizontal position (as shown in Fig. 5).

Then, the blade 22 continues to drive the transmission base 1 to rotate, causing the blade 23 to rotate. To the position opposite to FIG. 4, at this time, the blades 22, 23 have a windward resistance difference with a minimum windward area, and the blade 23 changes the center of gravity of the body to cause the first and second sides 231, 232 to rotate in the E direction and form. Balance (as shown in Figure 6).

Finally, as the transmission base 1 rotates inertially, the blades 23 gradually rotate the first and second sides 231, 232 in the F direction (as shown in Fig. 7) due to the increase in the wind receiving area, and can return to the original 3rd. The initial position of the figure is used to form a cycle of rotation of a blade 23.

Similarly, when the blades 22, 32, 33 rotate one turn with the transmission base 1, the same action changes as described above are also performed; thus, regardless of the direction of the wind, at least one set of blades has the largest windward area. The wind resistance is poorly affected, so that the power output efficiency of the transmission base 1 can be effectively improved, and the generator 12 can be optimally generated.
