[0030] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0031] As described in the background art, the blades cannot be adjusted according to real-time wind force changes, which is not conducive to wind energy utilization.
[0032] In order to solve this technical problem, the present invention provides a high-efficiency vertical axis wind turbine power generation device, which is used to regulate and utilize wind energy.
[0033] Specifically, please refer to Figure 1-Figure 5 A high-efficiency vertical axis wind turbine power generation device includes a sleeve 1 and a column 2, a rotating disk 3 and a rotating assembly 4, the column 2 is arranged in the sleeve 1 and connected to the rotating disk 3, the rotating assembly 4 is arranged on the rotating disk 3, the rotating assembly 4 includes an air adjustment mechanism 40 and a control and drive mechanism 41, the air adjustment mechanism 40 includes an air adjustment main board 401, an air adjustment sub-board 402 and an air adjustment plate 403, a plurality of air adjustment main boards 401 and air adjustment sub-boards 402 are arranged on the rotating disk 3, two air adjustment plates 403 are arranged on the air adjustment main board 401 and the air adjustment sub-board 402, two connecting shafts 404 are installed on the air adjustment main board 401 and one of them is connected to the air adjustment sub-board 402, synchronous chains are installed on the connecting shaft 404 and the rotating shaft of the air adjustment plate 403, and the two connecting shafts 404 are connected with meshing transmission air adjustment gears 405.
[0034] A plurality of air adjustment main plates 401 and air adjustment sub-plates 402 are arranged on the rotating disk 3. Under normal circumstances, the air adjustment plates 403 are in an initial state, and the two air adjustment plates 403 are in contact with each other. When the wind is strong or in a headwind state, the wind acts on the air adjustment main plate 401 and the air adjustment sub-plate 402. At this time, the connecting shaft 404 rotates accordingly. Since the two connecting shafts 404 are connected with meshing wind adjustment gears 405, the rotation of one connecting shaft 404 will drive the other connecting shaft 404 to rotate, and then drive the rotating shaft of the air adjustment plate 403 to rotate through the synchronous chain, so that the two air adjustment plates 403 are unfolded to reduce the area of contact with the wind. In addition, the control and drive mechanism 41 can control the angle of the air adjustment plate 403. When the wind direction is chaotic and strong, the wind adjustment plate 403 is kept in the unfolded state and the control angle is maintained, so that the fan can operate stably under different wind conditions, improve the wind energy capture efficiency, thereby avoiding or reducing the situation where strong wind blows the vertical fan too fast and causes overload damage.
[0035] The present invention provides a high-efficiency vertical axis wind turbine power generation device. Through the design of the wind adjustment mechanism 40, under normal wind conditions, the wind adjustment plates 403 fit together, which can capture wind energy to the greatest extent and improve the power generation efficiency of the vertical wind turbine. Under different wind conditions, the wind adjustment plates 403 can automatically adjust the angle and state to optimize the wind energy capture effect. When encountering strong winds or headwinds, the control and drive mechanism 41 controls the wind adjustment plates 403 to keep them unfolded, reducing the wind contact area and avoiding overload damage.
[0036] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.
[0037] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0038] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0039] Please refer to Figure 3-Figure 6 , a high-efficiency vertical axis wind turbine power generation device, whose control and drive mechanism 41 includes a control and drive motor 410, a clutch 411 and a central gear 412. The control and drive motor 410 is installed on the rotating disk 3 and the output end is connected to the clutch 411. The central gear 412 is installed on the clutch 411 and meshed with four transmission gears 413. The central axis of the transmission gear 413 and the connecting shaft 404 are both installed with a synchronous belt 414; when the angle of the wind adjustment plate 403 is controlled, the control and drive motor 410 is started, and its output end drives the clutch 411. When the clutch 411 is in the engaged state, the power is transmitted to the central gear 412 to mesh and drive the four transmission gears 413 to rotate. The transmission gear 413 drives the connecting shaft 404 to rotate through the synchronous belt 414, and finally realizes the angle control of the wind adjustment plate 403. When the wind force is large, the clutch 411 remains in the engaged state, so that the wind adjustment plate 403 remains in the unfolded state, reducing the wind contact area.
[0040] By controlling the cooperation of the drive motor 410, the clutch 411, the center gear 412, the transmission gear 413 and the synchronous belt 414, the angle of the wind adjustment plate 403 can be controlled and adjusted according to different wind conditions and power generation requirements, thereby improving the wind energy capture efficiency and the stability of the wind turbine.
[0041] Please refer to Figure 7 and Figure 8, a high-efficiency vertical axis wind turbine power generation device, wherein a lifting mechanism 5 is arranged on the sleeve 1, and the bending control between the air regulating main plate 401 and the air regulating auxiliary plate 402 is realized by the lifting mechanism 5, and the lifting mechanism 5 includes a lifting motor 501, a main gear 502 and a sub-gear 503, and the lifting motor 501 is installed on the rotating disk 3 and the output end is connected to the main gear 502, and the sub-gear 503 is meshed with the main gear 502, and a plurality of waist-shaped grooves 504 are provided on the sub-gear 503, and the waist-shaped grooves 504 are slidably matched with the ones located around the column 2 The support block 505 is provided with an electric drive wheel 506; when the lifting motor 501 is powered on, it drives the main gear 502 and the meshing transmission sub-gear 503 to rotate. As the sub-gear 503 rotates, the support block 505 moves within the trajectory defined by the waist-shaped groove 504, thereby clamping the surface of the column 2. At this time, the electric drive wheel 506 is powered on and rolls on the surface of the column 2, thereby pushing the column 2 up and down, so that it can be adjusted and adapted during maintenance, avoiding and reducing high-altitude operations.
[0042] By cooperating with the lifting motor 501, the main gear 502 and the sub-gear 503 of the lifting mechanism 5, the air regulating main plate 401 and the air regulating sub-plate 402 can be raised or lowered. When the fan needs to be maintained, it can be adjusted to a height that is convenient for maintenance personnel to operate, avoiding the risks and inconveniences caused by high-altitude operations.
[0043] A high-efficiency vertical axis wind turbine power generation device is further optimized, specifically, as Figure 3 As shown, the wind adjustment plates 403 are grouped in pairs, and the wind adjustment plates 403 are beveled on both sides to fit with the wind adjustment main plate 401 and the wind adjustment sub-plate 402; the wind adjustment plates 403 are beveled on both sides, and this shape makes the wind adjustment plates 403 fit more tightly with the wind adjustment main plate 401 and the wind adjustment sub-plate 402, thereby reducing wind leakage and improving the utilization efficiency of wind energy.
[0044] The wind adjustment plates 403 are designed to be arranged in pairs, and are closely fitted with the wind adjustment main plate 401 and the wind adjustment auxiliary plate 402, so that wind energy can be effectively captured. The beveled design on both sides of the wind adjustment plates 403 reduces wind leakage and improves utilization.
[0045] Further, such as Figure 3-Figure 6As shown, the end face of one of the connecting shafts 404 is connected to a reset torsion spring 406 installed with the air adjustment main board 401, and the end faces of the reset torsion spring 406 are respectively installed with the air adjustment main board 401 and one of the connecting shafts 404; if the wind force conditions change and need to be restored to the initial state, the reset torsion spring 406 connected to the end face of one of the connecting shafts 404 begins to play a role, and the reset torsion spring 406 stores elastic potential energy when deformed, and then drives the wind adjustment plate 403 to rotate back to the initial position through the synchronous chain, and also drives the meshing wind adjustment gear 405 and the other connecting shaft 404 to rotate, thereby realizing the reset of the entire air adjustment mechanism 40.
[0046] The reset torsion spring 406 provides an automatic reset function, so that the wind adjustment plate 403 can automatically return to the initial position after the wind force changes or the control signal is adjusted, thereby improving the adaptability and stability of the fan.
[0047] A high-efficiency vertical axis wind turbine power generation device is further optimized, specifically, as Figure 7-Figure 8 As shown, the electric drive wheel 506 is shaped such that the diameter at the end face is larger than the diameter at the center, and the electric drive wheel 506 transmits the column 2 through the corresponding positioning grooves provided on the column 2; the electric drive wheel 506 is shaped such that the diameter at the end face is larger than the diameter at the center, and due to its special shape design, when it contacts with the corresponding positioning grooves on the column 2, it can better fit the shape of the positioning grooves, thereby increasing friction and transmission stability.
[0048] The matching design of the electric drive wheel 506 and the positioning groove can reduce wear and tear, improve transmission effect and movement stability, and because the electric drive wheel 506 can better fit the positioning groove, unnecessary friction and vibration are reduced.
[0049] Further, such as Figure 7 As shown, there is a screw connected to the column 2 in a rotatable manner in the sleeve 1; the screw in the sleeve 1 is connected to the column 2. When the screw rotates, due to the rotational cooperation relationship between the sleeve 1 and the screw, the screw is in a rotating state when the column 2 moves, thereby achieving the effect of assisting the screw in positioning the column 2 on the support after the movement is completed.
[0050] The connection between the screw and the column 2 can increase the stability of the entire structure. The screw can fix the column 2 more firmly in the sleeve 1, reduce shaking and vibration, and reduce component damage and performance degradation caused by vibration.
[0051] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0052] Obviously, the embodiments described above are only some embodiments of the present invention, rather than all embodiments.

The present invention can be implemented in many different forms.
