[0003] In order to improve the automatic performance of the wind power generator and reduce the manual control of the direction of the wind power generator, the existing wind energy tracking device usually adopts a normal self-rotation posture adjustment mode, which stops the posture adjustment after finding the angle with the maximum wind force in the adjustment process. The direct setting of the rotating driving part at the end of the wind power generator has low precision and large rotation torque in the driving process, that is, the rotation degree is large in unit driving time, which is not conducive to the high-precision fine adjustment of the direction of the blade end of the wind power generator.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.
[0029] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.
[0030] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.
[0031] Example 1, referring to Figures 1-3 The first embodiment of the present invention provides a rolling reverse spiral wind energy tracking device, which includes a wind power generation unit 100, a wind energy conversion unit 200, and a control unit 300.
[0032] The wind power generation unit 100 includes a base 101 and power generation blades 102 mounted on the base 101. The wind energy conversion unit 200 includes a conversion chamber 201 mounted on the base 101, a wind energy conversion component 202 mounted within the conversion chamber 201, and a wind-following component 203 mounted on the conversion chamber 201 and connected to the power generation blades 102. The power generation blades 102 can drive the wind energy conversion component 202, which is rotatably mounted on the conversion chamber 201, to rotate. This allows the wind energy to be converted into electrical energy via a transformer within the wind energy conversion component 202, and then the voltage is output through the base 101. During this process, the setting angle of the conversion chamber 201 relative to the base 101 can be changed by the control of the wind-following component 203. The wind-following component 203 controls the conversion chamber 201 to rotate continuously. When the power generation blade 102 rotates continuously and outputs electrical energy, the wind-following component 203 and its connected control unit 300 stop working, so that the power generation blade 102 is oriented towards the angle with greater wind energy to generate wind power. When the power generation blade 102 cannot output electrical energy stably, the control unit 300 receives the instruction and starts working, thereby driving the power generation blade 102 and the conversion chamber 201 to start rotating.
[0033] The control unit 300 includes a drive component 301 mounted on the base 101 and used to drive the wind-following component 203, a guide component 302 mounted on the base 101 and connected to the drive component 301, and an electric push rod 303 mounted on the base 101 and connected to the guide component 302. The drive component 301 can generate linear motion under the drive of the electric push rod 303. The guide component 302 ensures the sliding stability of the drive component 301 within the base 101. The connection between the drive component 301 and the wind-following component 203 enables the wind-following component 203 to drive the conversion chamber 201 to rotate on the base 101, and can convert the linear motion of the drive component 301 into rotational motion. This process involves a small rotation angle per unit control time, enabling high-precision control of the conversion chamber 201.
[0034] During operation, the generator blades 102 drive the wind energy conversion assembly 202, which is rotatably mounted on the conversion chamber 201, to rotate. This allows the transformer within the wind energy conversion assembly 202 to convert wind energy into electrical energy, which is then output through the base 101. The angle between the conversion chamber 201 and the base 101 can be controlled by the wind-following assembly 203. The wind-following assembly 203 controls the conversion chamber 201 to rotate continuously. Once the generator blades 102 are continuously rotating and outputting electrical energy, the wind-following assembly 203 and its connected control unit 300 stop operating, allowing the generator blades 102 to generate wind power at an angle with greater wind energy. When the generator blades 102 cannot stably output electrical energy, the control unit 300 receives a command and begins operation, causing the generator blades 102 and the conversion chamber 201 to rotate. Driven by the electric push rod 303, the drive component 301 can generate linear motion. The guide component 302 ensures the sliding stability of the drive component 301 inside the base 101. The connection between the drive component 301 and the wind-following component 203 enables the wind-following component 203 to drive the conversion chamber 201 to rotate on the base 101 and convert the linear motion of the drive component 301 into rotational motion. The rotation angle is small per unit control time, which enables high-precision control of the conversion chamber 201.
[0035] Example 2, refer to Figures 1-7 This is the second embodiment of the present invention, which differs from the first embodiment in that: the wind-following component 203 includes a connector 203a disposed on the conversion chamber 201, a drive seat 203b disposed on the connector 203a, and a linkage sleeve 203c disposed on the drive seat 203b and drivenly connected to the drive component 301. The connector 203a includes a pin 203a-1 disposed on the drive seat 203b and the conversion chamber 201, and a fastening nut 203a-2 is also disposed on the pin 203a-1, thereby improving the connection strength between the drive seat 203b and the conversion chamber 201.
[0036] Compared to Embodiment 1, the drive seat 203b is further provided with a ball bearing 203b-1; the ball bearing 203b-1 is rotatably connected to the conversion chamber 201. The ball bearing 203b-1 can provide a buffer protection between the drive seat 203b and the conversion chamber 201, thereby preventing severe wear caused by the drive seat 203b rotating heavy objects such as the conversion chamber 201 and the generator blade 102 for a long time.
[0037] Furthermore, the drive assembly 301 includes a drive sleeve 301a disposed within the linkage sleeve 203c, and a threaded rod 301b slidably disposed on the drive sleeve 301a and the linkage sleeve 203c. Under the control of the electric push rod 303, the threaded rod 301b performs linear feed motion, thereby driving the drive sleeve 301a and the linkage sleeve 203c to rotate.
[0038] Furthermore, a drive ball 301a-1 is rotatably mounted on the drive sleeve 301a, a groove m corresponding to the drive ball 301a-1 is provided on the linkage sleeve 203c, and a threaded groove n corresponding to the drive ball 301a-1 is provided on the threaded rod 301b. When the threaded rod 301b and the linkage sleeve 203c are linked, the drive ball 301a-1 is rolled within the groove m and the threaded groove n. The drive ball 301a-1 is made of a material with high rigidity, good stability, high friction, and a smooth surface. When the threaded rod 301b drives the drive ball 301a-1 to slide within the threaded groove n, the drive ball 301a-1 can exert a force perpendicular to and axially on the drive sleeve 301a and the linkage sleeve 203c, thereby causing the drive sleeve 301a and the linkage sleeve 203c to rotate, thus driving the conversion chamber 201 to rotate on the base 101.
[0039] During operation, the generator blades 102 drive the wind energy conversion assembly 202, which is rotatably mounted on the conversion chamber 201, to rotate. This allows the transformer within the wind energy conversion assembly 202 to convert wind energy into electrical energy, which is then output through the base 101. The angle between the conversion chamber 201 and the base 101 can be controlled by the wind-following assembly 203. The wind-following assembly 203 controls the conversion chamber 201 to rotate continuously. Once the generator blades 102 are continuously rotating and outputting electrical energy, the wind-following assembly 203 and its connected control unit 300 stop operating, allowing the generator blades 102 to generate wind power at an angle with greater wind energy. When the generator blades 102 cannot stably output electrical energy, the control unit 300 receives a command and begins operation, causing the generator blades 102 and the conversion chamber 201 to rotate. Driven by the electric push rod 303, the drive component 301 can generate linear motion. The guide component 302 ensures the sliding stability of the drive component 301 inside the base 101. The connection between the drive component 301 and the wind-following component 203 enables the wind-following component 203 to drive the conversion chamber 201 to rotate on the base 101 and convert the linear motion of the drive component 301 into rotational motion. The rotation angle is small per unit control time, which enables high-precision control of the conversion chamber 201.
[0040] The remaining structure is the same as that in Example 1.
[0041] Example 3, referring to Figures 1-7 This is the third embodiment of the present invention, which differs from the second embodiment in that the guide component 302 includes a slider 302a disposed at the driving end of the driving component 301, an inner guide 302b disposed on the slider 302a and located on the base 101, and an outer guide 302c disposed on the slider 302a and located on the base 101. The guide component 302 limits the sliding of the slider 302a within the base 101, improving the stability of the sliding of the slider 302a and the threaded rod 301b on the base 101 driven by the electric push rod 303, and preventing misalignment, malfunction, or jamming during the driving process.
[0042] Compared to Embodiment 2, the inner guide member 302b further includes a guide groove 302b-1 disposed on the base 101, and a guide block 302b-2 disposed on the slider 302a and slidably disposed on the guide groove 302b-1. A sliding groove 302b-11 is provided on the guide groove 302b-1. The guide block 302b-2 can drive the slider 302a to slide on the guide groove 302b-1, thereby limiting the sliding of the slider 302a inside the base 101, improving the stability of the electric push rod 303 driving the slider 302a and the threaded rod 301b to slide on the base 101, and avoiding misalignment, malfunction, or jamming during the driving process.
[0043] Furthermore, the outer guide member 302c includes a guide rod 302c-2 disposed on the base 101 and parallel to the guide groove 302b-1, and a limiting strip 302c-1 slidably disposed on the guide rod 302c-2 and connected to the slider 302a. The limiting strip 302c-1 is slidably disposed on the guide rod 302c-2, thereby limiting the sliding of the slider 302a inside the base 101 and improving the stability of the sliding of the slider 302a and the threaded rod 301b on the base 101 driven by the electric push rod 303.
[0044] Preferably, the base 101 is provided with a through hole for sliding the limiting strip 302c-1, so that the limiting strip 302c-1 can slide within the visible range outside the base 101, thereby making it easier for the staff to observe the sliding of the limiting strip 302c-1 on the base 101, and thus determine whether the drive component 301 and the wind-following component 203 are working properly.
[0045] Preferably, the base 101 is provided with a solar cell 304 electrically connected to the electric actuator 303. During normal use, the electric actuator 303 is powered by the voltage generated by the wind power of the device itself, and the solar cell 304 can provide backup power for the electric actuator 303 to prevent the conversion chamber 201 from being unable to rotate when the wind force is low.
[0046] During operation, the generator blades 102 drive the wind energy conversion assembly 202, which is rotatably mounted on the conversion chamber 201, to rotate. This allows the transformer within the wind energy conversion assembly 202 to convert wind energy into electrical energy, which is then output through the base 101. The angle between the conversion chamber 201 and the base 101 can be controlled by the wind-following assembly 203. The wind-following assembly 203 controls the conversion chamber 201 to rotate continuously. Once the generator blades 102 are continuously rotating and outputting electrical energy, the wind-following assembly 203 and its connected control unit 300 stop operating, allowing the generator blades 102 to generate wind power at an angle with greater wind energy. When the generator blades 102 cannot stably output electrical energy, the control unit 300 receives a command and begins operation, causing the generator blades 102 and the conversion chamber 201 to rotate. Driven by the electric push rod 303, the drive component 301 can generate linear motion. The guide component 302 ensures the sliding stability of the drive component 301 inside the base 101. The connection between the drive component 301 and the wind-following component 203 enables the wind-following component 203 to drive the conversion chamber 201 to rotate on the base 101 and convert the linear motion of the drive component 301 into rotational motion. The rotation angle is small per unit control time, which enables high-precision control of the conversion chamber 201.
[0047] The remaining structure is the same as that in Example 2.
