Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to a flexible wind-gathering vertical axis wind power generation structure. Background Technology

[0002] Wind turbine power generation technology is quite mature, mainly divided into two categories: horizontal axis wind turbine structures and vertical axis wind turbine structures. Horizontal axis wind turbine structures have disadvantages such as higher cost and difficulties in installation and maintenance. Vertical axis wind turbine structures, on the other hand, have advantages such as strong self-starting capability, simple structure for easy maintenance, strong adaptability, and no need for yaw devices, attracting increasing attention from researchers and investors.

[0003] According to the structural principles of wind power generation, the power output is directly proportional to the cube of the wind speed. Therefore, increasing the wind speed can increase the power output, thereby improving the utilization rate of wind resources. Currently, known wind power generation structures typically use wind concentrators to increase the wind speed reaching the turbine. However, existing wind concentrators used in vertical axis wind power generation structures are mainly fixed, all-around covering mechanisms, which are costly and ineffective. Utility Model Content

[0012] As a further improvement to the above technical solution:

[0013] The yaw device includes a motor, which is mounted on the fixed frame, and the drive end of the motor is connected to the rotating frame.

[0038] like Figures 1 to 4As shown, the flexible wind-gathering vertical axis wind power generation structure of this embodiment includes: a support mechanism 30, including a fixed frame 32, a rotating frame 31 rotatably mounted on the fixed frame 32, and a yaw device 40, the yaw device 40 being used to drive the rotating frame 31 to rotate on the fixed frame 32; a wind-gathering mechanism 10, mounted on the rotating frame 31, including an air inlet and an air outlet, the air inlet area being larger than the air outlet area; and a vertical axis fan 20, mounted on the fixed frame 32.

[0039] It is understood that the flexible wind-gathering vertical axis wind power generation structure of this embodiment can be various types of vertical axis wind power generation structures, such as... Figure 1 The drag-type vertical axis wind power generation structure shown, or as... Figure 3 The lift-type wind power generation structure shown in this embodiment, specifically the vertical axis wind power generation structure, is applied to... Figure 1 The following explanation uses a drag-type vertical axis wind power generation structure as an example.

[0040] The fixed frame 32 is a support rod that can raise the height of the vertical axis fan 20. The vertical axis fan 20 is fixed on the fixed frame 32. The rotating frame 31 is a square frame that can rotate around the vertical axis fan 20, with the axial direction of the vertical axis fan 20's rotation axis as its rotation center. A bearing is provided between the rotating frame 31 and the fixed frame 32. Specifically, in this embodiment, the support rod passes through the entire rotating frame 31. The top and bottom of the rotating frame 31 are rotatably connected to the support rod through bearings. The vertical axis fan 20 is sleeved on the support rod between the top and bottom of the rotating frame 31. The fan 21 of the vertical axis fan 20 is fixedly connected to the support rod, while the fan blade assembly 22 is rotatably sleeved on the support rod. The fan blade assembly 22 is coaxial with the support rod. When the fan blade assembly 22 rotates, it drives the fan 21 to rotate and generate electricity.

[0041] In this embodiment, the air inlet area of ​​the air-gathering mechanism 10 is larger than the air outlet area. When the airflow flows from the large-area opening to the small-area opening, the air mass cannot accumulate in large quantities, so it accelerates through the small-area opening, increasing the wind speed. Therefore, the air-gathering device in this embodiment can make the wind speed output from the small-area air outlet greater than the wind speed entering the large-area air inlet.

[0042] In the flexible wind-gathering vertical axis wind power generation structure of this embodiment, natural wind enters through the large-area air inlet of the wind-gathering mechanism 10 and then exits through the small-area air outlet, thereby increasing the wind speed reaching the vertical axis wind turbine 20, thus improving the power generation efficiency of the vertical axis wind turbine 20 and enhancing the utilization rate of wind energy. In this embodiment, the yaw device 40 can also drive the rotating frame 31 and the wind-gathering mechanism 10 to rotate on the fixed frame 32, so that the air inlet of the wind-gathering mechanism 10 is always facing the direction of the wind, making the power generation efficiency of the vertical axis wind turbine 20 even higher and the utilization rate of wind energy even higher.

[0043] In one possible embodiment, such as Figure 1 As shown, the air-gathering mechanism 10 includes multiple air-gathering plates 111, which together form a trumpet-shaped air intake mechanism 11. The end of the air intake mechanism 11 with a smaller opening area is the air outlet of the air intake mechanism 11, and the end of the air intake mechanism 11 with a larger opening area is the air inlet of the air intake mechanism 11.

[0044] The air-gathering mechanism 10 includes multiple air-gathering plates 111. Each air-gathering plate 111 is a trapezoidal flat plate. The hypotenuses of the trapezoidal flat plates are connected to form a trumpet-shaped air-inlet mechanism 11. The top edges of all the trapezoidal flat plates constitute the air outlet of the air-inlet mechanism 11, and the bottom edges of all the trapezoidal flat plates constitute the air inlet of the air-inlet mechanism 11. The included angle β between the two hypotenuses of the trapezoidal flat plates is 0° < β < 180°.

[0045] The cross-section of the trumpet-shaped air intake mechanism 11 can be square, circular, or polygonal. In this embodiment, the cross-section of the air intake mechanism 11 is square. Specifically, in this embodiment, the air gathering mechanism 10 includes four air gathering plates 111. In other embodiments, it can also consist of three, five, or other numbers of air gathering plates 111. In this embodiment, the four air gathering plates 111 are trapezoidal flat plates of the same shape. Specifically, the trapezoidal flat plates are isosceles trapezoidal flat plates. The hypotenuses of the four trapezoidal flat plates are connected in sequence to form the trumpet-shaped air intake mechanism 11. Since the length of the top side of the trapezoidal flat plate is greater than the length of the bottom side, the top side of all the trapezoidal flat plates constitutes the air outlet of the air intake mechanism 11, and the bottom side of all the trapezoidal flat plates constitutes the air inlet of the air intake mechanism 11. The included angle β between the two hypotenuses of the trapezoidal flat plate is 0° < β < 180°. In this embodiment, β is specifically 60°. The air gathering plates 111 in this embodiment are trapezoidal flat plates to construct the trumpet-shaped air intake mechanism 11.

[0046] In the flexible wind-gathering vertical axis wind power generation structure of this embodiment, when the wind enters through the air inlet, the air intake mechanism 11 restricts the wind escape, and the wind can only be discharged through the air outlet. Since the air mass cannot accumulate in large quantities, it accelerates through the small area opening, thereby making the wind speed at the air outlet faster and the power generation efficiency of the vertical axis wind turbine located at the air outlet higher.

[0047] In one possible embodiment, such as Figure 2 As shown, the air-gathering mechanism 10 also includes a hollow channel 12 and an air outlet mechanism 13. The air outlet mechanism 13 has the same shape as the air inlet mechanism 11. The air inlet mechanism 11 and the air outlet mechanism 13 are respectively installed on opposite sides of the rotating frame 31. The two ends of the hollow channel 12 are respectively connected to the air inlet mechanism 11 and the air outlet mechanism 13. The vertical axis fan 20 is located in the hollow channel 12. The geometric centers of the air inlet mechanism 11, the hollow channel 12 and the air outlet mechanism 13 are located in the same plane.

[0048] It is understandable that in large vertical axis wind power generation structures, since the air inlet of the air inlet mechanism 11 needs to cover the entire vertical axis wind turbine 20, the volume of the air inlet mechanism 11 on one side of the rotating frame 31 will also be very large. The large volume of the air inlet mechanism 11 will cause uneven stress on the rotating frame 31, making the vertical axis wind power generation structure risky from tipping over. In this embodiment, an air outlet mechanism 13 is provided on the opposite side of the air inlet mechanism 11. Since the air outlet mechanism 13 has the same shape as the air inlet mechanism 11, the air outlet mechanism 13 can balance the weight of the air inlet mechanism 11, so that the rotating frame 31 is evenly stressed on both sides and maintains rotation. The stability of the moving frame 31; wherein, the cross-section of the hollow channel 12 can be square, circular, polygonal or other arbitrary regular or irregular shape. This embodiment takes a square hollow channel 12 as an example for explanation. The square hollow channel 12 can prevent the wind from escaping in all directions; the geometric centers of the air inlet mechanism 11, the hollow channel 12 and the air outlet mechanism 13 are located on the same plane, thereby constructing a channel that allows the wind to flow smoothly. The wind entering the air inlet mechanism 11 must pass through the vertical axis fan 20 before it can flow out from the air outlet mechanism 13, further enhancing the power generation efficiency of the vertical axis fan 20.

[0049] In another possible embodiment, such as Figure 3 and Figure 6 As shown, the wind-gathering mechanism 10 includes at least two non-parallel wind-gathering plates 111. The two wind-gathering plates 111 are symmetrically arranged opposite each other, and the included angle α between the wind-gathering plates 111 is 0° < α < 180°.

[0050] Specifically, in this embodiment, there are two wind-gathering plates 111. The two wind-gathering plates 111 are square plates and are symmetrically fixed on the rotating frame 31. The included angle α between the two wind-gathering plates 111 is 60°. This arrangement can make the air inlet area of ​​the wind-gathering mechanism 10 larger than the air outlet area, thereby increasing the wind speed at the air outlet. At the same time, the wind-gathering mechanism 10 in this embodiment has a simple structure and lower manufacturing cost.

[0051] In one possible embodiment, such as Figure 4 and Figure 5 As shown, the yaw device 40 includes a motor 42, which is mounted on a fixed frame 32, and the drive end of the motor 42 is connected to a rotating frame 31.

[0052] Specifically, the yaw device 40 also includes a wind vane 421, a transmission device 423, and a control device. The wind vane 421 and the motor 42 are both mounted on the fixed frame 32 and electrically connected to the control device. The first end of the transmission device 423 is connected to the rotating shaft of the motor 42, and the second end of the transmission device 423 is connected to the rotating frame 31.

[0053] It is understood that the wind vane 421 is mounted on the fixed frame 32. The initial direction of the wind vane 421 is set to be consistent with the opening direction of the wind gathering mechanism 10. The wind direction is monitored by the tail fin of the head of the wind vane 421. When the wind direction is inconsistent with the opening direction of the wind gathering mechanism 10, the wind vane 421 transmits the deflection angle between the wind gathering mechanism 10 and the wind direction to the control device in the form of an electrical signal. The control device is equipped with a control chip. The control chip can obtain the electrical signal and control the motor 42 to rotate. The control device controls the amount of rotation of the motor 42, and then drives the rotating frame 31 to deflect at the same angle as the wind direction through the transmission device.

[0054] In one possible embodiment, the yaw device 40 further includes an anemometer 422 electrically connected to the control device, and the transmission device 423 includes a first gear 4231 and a second gear 4232. The first gear 4231 is mounted on the rotating shaft of the motor 42, and the second gear 4232 is fixedly mounted on the rotating frame 31. The first gear 4231 meshes with the second gear 4232.

[0055] The anemometer 422 can acquire wind speed. The motor 42 can only be started when the control device detects that the wind speed acquired by the anemometer 422 reaches a preset threshold. In this embodiment, the preset threshold is the minimum wind speed at which the vertical axis fan 20 can generate electricity. When the wind speed is low, the motor 42 is turned off to avoid mechanical wear and energy waste.

[0056] In this embodiment, the motor 42 is used to drive the rotating frame 31 to rotate. Since the rotation axis of the rotating frame 31 is the same as the axis of the fixed frame 32, the motor 42 cannot directly drive the rotating frame 31 to rotate through the rotating shaft. In this embodiment, the second gear 4232 is rotatably sleeved on the fixed frame 32. Therefore, the axis of the second gear 4232 is the same as the rotation axis of the rotating frame 31. The motor 42 drives the first gear 4231 to rotate, thereby driving the second gear 4232 and the rotating frame 31 to rotate.

[0057] It is understood that the transmission device 423 transmits the rotational motion of the motor 42 shaft to the rotating frame 31, thereby enabling the motor 42 to drive the rotating frame 31 to rotate. Therefore, the transmission device 423 is not limited to the gear transmission device in this embodiment. In other embodiments, belt transmission or ratchet mechanism transmission can also be used for transmission. Alternatively, in some embodiments, the motor 42 shaft can be made coaxial with the rotation axis of the rotating frame 31, thereby eliminating the need for the transmission device 423 and allowing the motor 42 to directly drive the rotating frame 31 to rotate.

[0058] In one possible embodiment, such as Figure 1 and Figure 3 As shown, the yaw device 40 also includes a tail fin plate 41, which is mounted on the rotating frame 31 and is positioned opposite to the wind-gathering mechanism 10.

[0059] It is understood that the tail fin 41 is installed on the side of the rotating frame 31 opposite to the air intake mechanism 11 of the wind gathering mechanism 10, so as to balance the weight of the wind gathering mechanism 10 and make the overall structure more stable. The extension direction of the tail fin 41 is consistent with the air intake direction of the wind gathering mechanism 10. Therefore, when the tail fin 41 is not consistent with the wind direction, the tail fin 41 will be subjected to wind pressure and thus generate a deflection force. This deflection force will drive the tail fin 41 to rotate, thereby driving the rotating frame 31 and the wind gathering mechanism 10 to rotate until the extension direction of the tail fin 41 is consistent with the wind direction. At this time, the air intake of the wind gathering mechanism 10 will also face the oncoming wind direction. The tail fin 41 can make the air intake of the wind gathering mechanism 10 always face the oncoming wind.

[0060] It should be noted that the vertical axis wind power generation structure of this embodiment can be configured to drive the rotating frame 31 to rotate using only the motor 42, so that the opening of the wind gathering mechanism 10 can rotate to face the direction of the wind with higher accuracy; or it can be configured to drive the rotating frame 31 to rotate using only the tail fin plate 41, so that the structure is simpler; or it can be configured to drive the rotating frame 31 to rotate using both the tail fin plate 41 and the motor 42, so that the wind gathering mechanism 10 has higher reliability in wind direction.

[0061] In one possible embodiment, such as Figure 1 and Figure 3 As shown, the tail fin plate 41 includes two flat plates, and the two tail fin plates 41 are located at the upper and lower ends of the rotating frame 31 on the side away from the wind gathering mechanism 10.

[0062] It is understood that the tail fin plate 41 in this embodiment is two flat plates, which can be square, circular or other irregular polygons. In this embodiment, the tail fin plate 41 is specifically an irregular quadrilateral flat plate. The two tail fin plates 41 are symmetrically installed on the upper and lower ends of the side of the rotating frame 31 away from the wind-gathering mechanism 11. This can balance the weight of the wind-gathering mechanism 10 of the rotating frame 31 and maintain structural stability. The two tail fin plates 41 have a larger wind-receiving area. When the tail fin plate 41 is not aligned with the wind direction, the tail fin plate 41 will be subjected to greater wind pressure and thus generate greater deflection force.

[0063] In one possible embodiment, such as Figures 1 to 3 As shown, the support mechanism 30 also includes an auxiliary bracket 33, one end of which is connected to the rotating frame 31, and the other end is rotatably mounted on the fixed frame 32.

[0064] It is understandable that when the size of the wind gathering mechanism 10 is large, the wind gathering mechanism 10 is greatly affected by its own weight. In this embodiment, an auxiliary support 33 is set below the rotating frame 31 as an auxiliary support. The upper part of the auxiliary support 33 is fixed to the rotating frame 31, and the lower part is a slip ring structure, which is connected to the fixed frame 32 through pulleys. The auxiliary support 33 can rotate relative to the fixed frame 32 with the rotating frame 31.

[0065] In one possible embodiment, the vertical axis fan 20 includes a fan 21 and a fan blade assembly 22, the fan blade assembly 22 being rotatably mounted on the fan 21, and the fan 21 being mounted on a mounting frame 32.

[0066] The wind turbine assembly 22 includes a wind turbine blade and a rotating shaft. The wind turbine blade is connected to the fan 21 via the rotating shaft. When the wind turbine blade is blown by the wind, it will drive the rotating shaft to rotate. When the rotating shaft rotates, the fan 21 generates electricity. The air intake mechanism 11 of the wind concentrator 10 increases the wind speed reaching the wind turbine blade, thereby enhancing the power generation efficiency.

[0067] The flexible wind-gathering vertical axis wind power generation structure provided in the above embodiments of this application has at least the following characteristics:

[0068] 1. The air inlet area of ​​the wind concentrator 10 is larger than the air outlet area. When the airflow flows from the large area opening to the small area opening, the air mass cannot accumulate in large quantities, so it accelerates through the small area opening, thereby increasing the wind speed reaching the vertical axis fan 20, which in turn makes the vertical axis fan 20 have greater power generation efficiency and higher wind energy utilization.

[0069] 2. The tail fin plate 41 and / or motor 42 can drive the rotating frame 31 to rotate together with the wind gathering mechanism 10, so that the air inlet of the wind gathering mechanism 10 always faces the direction of the wind, further enhancing the utilization rate of wind energy.

[0070] 3. The tail fin 41 can also balance the weight of the wind-gathering mechanism 10, making the overall structure more stable.

[0071] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
