Description

Technical Field

[0001] The present invention belongs to the technical field of wind power generation, and in particular, relates to a vertical wind power generation device. Background Art

[0002] As society progresses, the demand for energy increases, and new energy sources have become a hot topic of research. Wind power generation, as a new energy source, converts wind power into electrical energy through wind power generation devices. It has become a hot topic in people's research on new energy sources. In the prior art, there are various types of wind power generation devices, including vertical wind power generation devices, which convert wind energy into electrical energy through the rotation of blades. Therefore, how to improve the power generation efficiency of vertical wind power generation devices has become a focus of attention.

[0003] There are various types of existing vertical wind power generation devices. For example, Chinese invention patent CN116447075A discloses a vertical axis wind power generation linkage blade structure, which includes a blade body, and the blade body is fixedly arranged on a vertical transmission shaft. The blade body obtains wind energy to drive the transmission shaft to rotate. The blade body includes a plurality of horizontal circular array distributed cross bars, the middle of the cross bar is fixedly installed on the transmission shaft, and wind film frames are movably arranged at both ends of the cross bar. The wind film frame can rotate along the connection between it and the cross bar at an angle not greater than 90 degrees. A wind film is installed on the wind film frame, and the connection end of the wind film frame and the cross bar is a rotating end. A steel wire rope is connected to the free end of the wind film frame away from the rotating end. The two wind film frames on the cross bar are connected together by the same steel wire rope, so that when one of the wind film frames on the same cross bar is unfolded to face the wind, it can pull the other wind film frame back to avoid the headwind. The above-mentioned blade structure achieves the purpose of wind power generation by expanding or contracting the wind film to obtain wind energy, thereby ensuring the acquisition of electric energy.

[0004] However, the above-mentioned fan blade structure still has the following problems in actual use: the fan blades are unfolded by pulling the wire rope to obtain wind energy, but the expansion and contraction of the fan blades cooperate with each other to overcome wind resistance and obtain wind energy to drive the transmission shaft to rotate, but the effect of overcoming wind resistance in the above-mentioned structure is not obvious enough, resulting in low power generation efficiency. Therefore, how to improve the power generation efficiency of wind power generation devices has become a hot research issue in the field of wind power generation.

[0005] To this end, the present invention provides a vertical wind power generation device to overcome wind resistance to the greatest extent and ensure the wind power generation efficiency of the power generation device. Summary of the invention

DETAILED DESCRIPTION

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one 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 term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0026] Example 1 like Figure 1 as well as Figure 2 As shown, it is a schematic diagram of the structure of the vertical wind power generation device in this embodiment. Figures 1 to 4 As shown, the vertical wind power generation device in this embodiment includes a rotating shaft 1, and a bracket 2 is installed on the side wall of the rotating shaft 1. Fig.10 as well as Fig.11As shown, a connecting plate 21 is installed at the end of the bracket 2, and the end of the connecting plate 21 is also connected to the fixed wing 3, and the end of the connecting plate 21 is connected to the variable wing 4. In this embodiment, wind force can drive the fixed wing 3 and the variable wing 4 to rotate, thereby driving the rotating shaft 1 to rotate, thereby achieving the effect of wind power generation.

[0027] like Figure 2 as well as Figure 3 As shown, in this embodiment, the fixed wing 3 is a semicircular structure, and the variable wing 4 is an arc structure. In this embodiment, the curvature of the fixed wing 3 is greater than the curvature of the variable wing 4. The diameter of the fixed wing 3 is H, and the radius of the variable wing 4 in this embodiment is greater than H. In addition, the variable wing 4 can rotate relative to the fixed wing 3 at the rotating shaft 22 to maximize the wind force, thereby driving the variable wing 4 and the fixed wing 3 to rotate the rotating shaft 1 through the bracket 2.

[0028] like Figure 2 As shown, in this embodiment, when the wind blows toward the surface of the fixed wing 3, since the fixed wing 3 is a semicircular structure, the rapid blowing of the wind causes a local negative pressure to be generated on the surface of the fixed wing 3 to generate lift, and since the variable wing 4 is in an open state, the wind blows the variable wing 4 to generate thrust. Therefore, the variable wing 4 and the fixed wing 3 can rotate in coordination to achieve the purpose of wind power generation.

[0029] Photovoltaic panels can be attached to the surfaces of the fixed wing 3 and the variable wing 4 to further generate electricity using sunlight outdoors. The electricity generated by the photovoltaic power generation can be stored as a backup power source for the operation of the device, and can also be connected to the power grid along with wind power generation.

[0030] like Figure 1 , Figures 4 to 8 As shown, in this embodiment, a mechanical driving mechanism 5a is also installed on the rotating shaft 1. In this embodiment, in order to ensure that the variable wing 4 can receive wind force to the maximum extent, the variable wing 4 in this embodiment is rotatably installed on the end of the connecting plate 21 through the rotating shaft 22, and the mechanical driving mechanism 5a on the rotating shaft 1 drives the variable wing 4 to rotate, so that the variable wing 4 can receive wind force to the maximum extent, thereby driving the rotating shaft 1 to rotate to achieve the purpose of wind power generation.

[0031] In this embodiment, the mechanical driving mechanism 5a includes a fixed shaft 51a built into the rotating shaft 1 and rotatably connected to the rotating shaft 1. The fixed shaft 51a extends to the outside of the top of the rotating shaft 1, and a rotating shell 53a is rotatably connected to the fixed shaft 51a. The top of the rotating shell 53a is rotatably connected to an upper cover 52a. Figure 7 As shown, in this embodiment, an eccentric slideway 55a is provided on the lower surface of the upper cover 52a. Figure 5As shown, in this embodiment, a guide hole 57a is provided on the side wall of the rotating shell 53a, the eccentric slide 55a is connected to the variable wing 4 through a connecting rod 56a, and one end of the connecting rod 56a is slidably assembled in the eccentric slide 55a, and the other end of the connecting rod 56a is slidably assembled on the variable wing 4. In this embodiment, the connecting rod 56a passes through the guide hole 57a and is slidably assembled with the rotating shell 53a. In this embodiment, when the variable wing 4 causes the rotating shaft 1 to rotate due to wind force, the rotating shell 53a rotates on the fixed shaft 51a, so the rotating shell 53a rotates synchronously with the rotating shaft 1, and the variable wing 4 rotates through The rotating shell 53a is driven to rotate by the connecting rod 56a. At this time, the upper cover 52a is in a stationary state, and when the variable wing 4 rotates, the connecting rod 56a is driven to rotate so that the end of the connecting rod 56a slides along the eccentric slide 55a. Since the slide 55a is an eccentric structure, when the end of the connecting rod 56a moves along the slide 55a, the connecting rod 56a extends or retracts from the rotating shell 53a along the length direction of the connecting rod 56a, thereby pushing the variable wing 4 to rotate, so as to better accept the blowing of wind to increase the rotation speed of the fixed wing 3 and the variable wing 4, improve the efficiency of wind power generation, and thus ensure the power generation effect.

[0032] like Figure 4 As shown, in this embodiment, a push slide groove 58a is horizontally installed on the inner wall of the variable wing 4. Figure 8 As shown, the variable wing 4 is connected to the slide 55a through a connecting rod 56a. In this embodiment, a guide wheel 562 is rotatably installed at one end of the connecting rod 56a, and the guide wheel 562 is rollingly installed in the slide 55a, and a sliding column 561 is rotatably installed at the other end of the connecting rod 56a, and the sliding column 561 is slidably installed in the pushing slide groove 58a. In this embodiment, when the variable wing 4 rotates to drive the connecting rod 56a to move in the eccentric slide 55a, the end of the connecting rod 56a moves along the slide 55a of the eccentric structure, thereby realizing that the connecting rod 56a extends or retracts from the rotating shell 53a along the length direction of the connecting rod 56a, and the other end of the connecting rod 56a slides along the length direction of the pushing slide groove 58a, thereby pushing or pulling the variable wing 4 to rotate, and then the wind force can be met to the maximum extent, and the power generation efficiency of the wind power generation device can be guaranteed.

[0033] In this embodiment, when wind blows toward the variable wing 4 and the fixed wing 3, the variable wing 4 facing the wind direction opens due to the action of the wind, and the connecting rod 56a moves due to the opening of the variable wing 4, so that the end of the connecting rod 56a moves in the eccentric slide 55a, and the variable wing 4 facing away from the wind direction contracts due to the action of the wind, thereby pushing the connecting rod 56a to move toward the inside of the rotating shell 53a, so that the end of the connecting rod 56a moves in the eccentric slide 55a. Therefore, when the variable wing 4 and the fixed wing 3 in this embodiment rotate synchronously with the rotating shaft 1, the end of the connecting rod 56a moves in the eccentric slide 55a. Therefore, the wind can be converted into electricity through the rotation of the fixed wing 3 and the variable wing 4 to achieve the purpose of power generation. In addition, since the variable wing 4 itself is rotatable, the variable wing 4 can meet the wind to the maximum extent and avoid the wind by contraction, so that the rotation of the variable wing 4 and the fixed wing 3 is faster, the power generation efficiency is improved, and the power generation effect is guaranteed.

[0034] In addition, when the wind direction changes, the windward effect of the variable wing 4 will decrease. In order to ensure that the variable wing 4 can face the wind to the maximum extent when the wind direction changes, so as to generate electricity through the rotation of the wind, as shown in FIG. Figure 6 As shown, a gear ring 543 is fixedly mounted on the lower surface of the upper cover 52a in this embodiment. The gear ring 543 is assembled on the top of the fixed shaft 51a through a bearing 59a, and as shown in FIG. Figure 5 As shown, in this embodiment, a servo motor 541 is fixedly installed on the fixed shaft 51a, and the power end of the servo motor 541 is connected to a driving gear 542, and the driving gear 542 is meshed with a gear ring 543. In this embodiment, when the wind direction changes, the servo motor 541 works to drive the driving gear 542 to rotate, thereby driving the gear ring 543 to drive the upper cover 52a to rotate, so that the direction of the eccentric slide 55a is adjusted, so that the variable wing 4 at different positions is in different states, so as to facilitate the adjustment of the variable wing 4 to open to the wind and shrink to the leeward side, so that the variable wing 4 can be blown by the wind to the greatest extent, thereby ensuring the rotation effect of the variable wing 4 and the fixed wing 3.

[0035] It is worth noting that the servo motor 541 in the present embodiment is a self-locking motor, that is, when the servo motor 541 stops working, the driving gear 542 cannot rotate. Since the driving gear 542 and the gear ring 543 are meshed with each other, the gear ring 543 and the upper cover 52a can be ensured to be in a locked state. In the present embodiment, when the fixed wing 3 and the variable wing 4 rotate due to the action of wind force, the rotating shell 53a and the rotating shaft 1 can be driven to rotate, and the fixed shaft 51a and the upper cover 52a are in a stationary state, so that the fixed wing 3 and the variable wing 4 can rotate smoothly. Among them, the variable wing 4 can be expanded or retracted due to the action of the connecting rod 56a, so that the variable wing 4 can receive wind force to the maximum extent to ensure the rotation speed, thereby improving the power generation effect.

[0036] Example 2 like Fig. 9 As shown, it is a structural schematic diagram of the vertical wind power generation device in this embodiment. The difference between this embodiment and embodiment 1 is that the power source for the expansion or contraction of the variable wing 4 is different. The vertical wind power generation device in the embodiment includes a rotating shaft 1, a bracket 2 is installed on the side wall of the rotating shaft 1, the end of the bracket 2 is connected to a connecting plate 21, and the end of the connecting plate 21 is installed with a fixed wing 3 and a variable wing 4, and the variable wing 4 is rotatably installed on the end of the connecting plate 21. The structure of the variable wing 4 and the fixed wing 3 in this embodiment is the same as that in embodiment 1. The fixed wing 3 is a semicircular structure, and the variable wing 4 is an arc structure. The curvature of the fixed wing 3 is greater than the curvature of the variable wing 4. The diameter of the fixed wing 3 is H, and the radius of the variable wing 4 in this embodiment is greater than H. In addition, the variable wing 4 can rotate relative to the fixed wing 3 with the rotating shaft 22 to maximize the wind force, thereby driving the variable wing 4 and the fixed wing 3 to drive the rotating shaft 1 to rotate through the bracket 2.

[0037] like Fig. 9 As shown, in this embodiment, a telescopic driving mechanism 5b is further installed between the bracket 2 and the variable wing 4, and the telescopic driving mechanism 5b can drive the variable wing 4 to rotate, so that the variable wing 4 can receive wind energy to the maximum extent and can rotate.

[0038] like Fig. 9 As shown, in this embodiment, the telescopic driving mechanism 5b includes a rotating shaft 53b rotatably installed between the brackets 2, and an electric telescopic rod 52b is connected to the rotating shaft 53b. The power end of the electric telescopic rod 52b is connected to a hinge seat 51b, and the hinge seat 51b is installed on the variable wing 4. In this embodiment, when the telescopic driving mechanism 5b works to extend or retract, it can push or pull the variable wing 4 to rotate, and then the expansion and contraction state of the variable wing 4 can be changed to ensure that the variable wing 4 can receive wind energy to the maximum extent, ensure the rotation effect of the variable wing 4, and thus improve the power generation efficiency of the wind power generation device.

[0039] Example 3 like Fig.10As shown, it is a structural schematic diagram of the vertical wind power generation device in this embodiment. The difference between this embodiment and embodiment 1 is that the power source for the expansion or contraction of the variable wing 4 is different. The vertical wind power generation device in the embodiment includes a rotating shaft 1, a bracket 2 is installed on the side wall of the rotating shaft 1, the end of the bracket 2 is connected to a connecting plate 21, and the end of the connecting plate 21 is installed with a fixed wing 3 and a variable wing 4, and the variable wing 4 is rotatably installed on the end of the connecting plate 21. The structure of the variable wing 4 and the fixed wing 3 in this embodiment is the same as that in embodiment 1. The fixed wing 3 is a semicircular structure, and the variable wing 4 is an arc structure. The curvature of the fixed wing 3 is greater than the curvature of the variable wing 4. The diameter of the fixed wing 3 is H, and the radius of the variable wing 4 in this embodiment is greater than H. In addition, the variable wing 4 can rotate relative to the fixed wing 3 with the rotating shaft 22 to maximize the wind force, thereby driving the variable wing 4 and the fixed wing 3 to drive the rotating shaft 1 to rotate through the bracket 2.

[0040] In this embodiment, a translation drive mechanism 5c is installed between the bracket 2 and the variable wing 4, and the translation drive mechanism 5c can drive the variable wing 4 to expand or retract, so that the variable wing 4 can receive wind energy to the greatest extent.

[0041] like Fig.11 as well as Fig.12 As shown, in this embodiment, the translation drive mechanism 5c includes a support shaft 53c rotatably installed between the brackets 2, and a connecting rod 51c is installed on the support shaft 53c. In this embodiment, a movable groove 52c is installed on the side wall of the variable wing 4, and a walking wheel assembly 56c is installed in the movable groove 52c. The walking wheel assembly 56c is installed in the movable groove 52c and can be moved in the movable groove 52c by being driven by a power mechanism. In this embodiment, a translation slide 55c is connected to the walking wheel assembly 56c. When the walking wheel assembly 56c moves in the movable groove 52c, the translation slide 55c can be driven to move along the length direction of the movable groove 52c. In this embodiment, a hinge 54c is installed on the translation slide 55c, and one end of the connecting rod 51c is installed on the support shaft 53c, and the other end is hinged on the hinge seat 54c.

[0042] In this embodiment, when the walking wheel assembly 56c drives the translation slide 55c to move in the moving groove 52c, the translation slide 55c pulls the connecting rod 51c to move, thereby causing the variable wing 4 to rotate to adjust the degree of expansion and contraction of the variable wing 4, so as to meet the wind energy to the greatest extent, thereby driving the variable wing 4 and the fixed wing 3 to drive the rotating shaft 1 to rotate through the wind energy, thereby ensuring the working efficiency of the vertical wind power device and the power generation effect.
