Description

Technical Field

[0001] This utility model relates to the field of clean energy power generation technology, and in particular to a combined wind power and photovoltaic power generation system. Background Technology

[0002] In existing technologies, wind power and photovoltaic power generation are two relatively traditional clean energy power generation technologies. Wind power generation generally uses wind turbines, which include a horizontal shaft with multiple wind turbine blades spaced apart circumferentially on the horizontal shaft. A gearbox is connected to the horizontal shaft and the gearbox is connected to the generator.

[0003] Photovoltaic power generation generally includes a photovoltaic support structure, on which multiple photovoltaic panels (solar panels) are installed to generate electricity using solar energy.

[0004] In traditional technologies, in order to improve land utilization, there have been three-dimensional photovoltaic power generation systems that have arranged multiple photovoltaic panels at intervals along a photovoltaic support in a vertical direction. However, this only increases the utilization effect of photovoltaic power generation. Since photovoltaic power generation is time-limited and can only generate electricity during the day, it cannot maximize the utilization of natural resources.

[0005] Chinese patent CN116169943A discloses a "wind and photovoltaic complementary power generation system," which includes a pole with two sets of photovoltaic panels spaced vertically on it. A wind turbine is mounted on top of the pole, and wind turbine blades are connected to the turbine, thus achieving the integrated utilization of solar and wind energy. However, this combination has the following problems: to improve wind energy capture rate, the wind turbine blades are relatively long and have a large rotation radius, resulting in a large vertical footprint. This also limits the number of photovoltaic panels that can be used, making the entire system tall and heavy, which makes it unsuitable for certain applications, such as rooftops. Utility Model Content

[0006] The purpose of this utility model is to provide a wind power and photovoltaic combined power generation system to solve the technical problem that the long length of wind turbine blades in the prior art leads to a high overall height of the equipment.

[0007] To solve the above-mentioned technical problems, the technical solution of the wind power and photovoltaic combined power generation system of this utility model is as follows:

[0008] A combined wind and solar power generation system includes a system support frame. One and at least two sets of photovoltaic panels are spaced apart vertically on the system support frame, with the sun-facing side of the photovoltaic panels facing forward. A wind power generation device is also mounted on the system support frame, positioned below a corresponding set of photovoltaic panels. The wind power generation device can be configured in two ways: First, the wind power generation device includes a wind turbine shaft with its axis extending horizontally. A power generation mechanism is connected to the wind turbine shaft, and multiple circumferentially spaced wind-blocking blades are fixed to the wind turbine shaft. A wind guide device is mounted on the system support frame to guide wind towards the wind-blocking blades, causing the wind turbine shaft to rotate. Second, the wind power generation device includes a first transmission wheel and a second transmission wheel with their axes extending horizontally or vertically. A circulating transmission component is wound around the first and second transmission wheels, and multiple circumferentially spaced wind-blocking blades are mounted on the circulating transmission component. At least one transmission wheel is connected to a power generation mechanism. A wind guide device is mounted on the system support frame to guide wind towards the wind-blocking blades, causing the circulating transmission component to rotate.

[0009] Furthermore, there are at least two sets of photovoltaic panels, and the gap between two adjacent sets of photovoltaic panels in the vertical direction forms the air guiding channel of the air guiding device, with the wind-blocking blades located on the rear side of the air guiding channel.

[0010] Furthermore, there are at least two sets of photovoltaic panels. Two sets of photovoltaic panels that are adjacent in the vertical direction are defined as the upper photovoltaic panel and the lower photovoltaic panel. The wind power generation device adopts the first type. The wind guiding device includes an upper wind guide hood and a lower wind guide hood. The upper wind guide hood guides the wind to the wind deflector blades on the upper side of the wind turbine shaft from back to front. The lower wind guide hood guides the wind to the wind deflector blades on the lower side of the wind turbine shaft from front to back. The upper wind guide hood and the lower wind guide hood are located between two sets of photovoltaic panels that are adjacent in the vertical direction. The air intake directions of the upper wind guide hood and the lower wind guide hood are opposite.

[0011] Furthermore, the inner cavities of the upper and lower air guide hoods form air guide channels. The size of the air guide channel of the upper air guide hood gradually decreases from back to front, and the size of the air guide channel of the lower air guide hood gradually decreases from front to back.

[0012] Furthermore, the upper air guide shroud is set independently of the upper photovoltaic panel, and the lower air guide shroud is set independently of the lower photovoltaic panel.

[0013] Furthermore, the air guide channel of the upper air guide shroud is formed by the bottom of the upper air guide shroud and the upper photovoltaic panel, and / or the air guide channel of the lower air guide shroud is formed by the top of the lower air guide shroud and the lower photovoltaic panel.

[0014] Furthermore, the lowest position of the wind deflector blade is not lower than the lowest position of the corresponding photovoltaic panel, and the upper wind guide is located at the rear end of the photovoltaic panel. After the wind is guided by the photovoltaic panel, it enters the upper wind guide.

[0015] Furthermore, the wind power generation device adopts a second form, in which the wind guide device is distributed on one or both sides of the circulating transmission component. Each side of the wind guide device includes at least two wind guide shrouds arranged along the rotation direction of the circulating transmission component. Each wind guide shroud has a wind guide channel for guiding the wind to the corresponding wind deflector blade so that the circulating transmission component generates a rotational torque in the same direction.

[0016] Furthermore, the air guiding device includes a movable air guiding hood and a fixed air baffle arranged vertically. The fixed air baffle has a fixed air baffle guide channel for guiding the air to the corresponding air baffle blade. The movable air guiding hood is rotatably mounted on the upper end of the fixed air baffle. The rotation axis of the movable air guiding hood extends in the vertical direction. The movable air guiding hood has an air guiding hood inlet located on the upper side of the corresponding photovoltaic panel.

[0017] Furthermore, the movable air guide is equipped with a wind direction indicator structure for adjusting the rotation of the movable air guide according to the wind direction.

[0018] The beneficial effects of this utility model are as follows: Compared with the prior art, the wind power generation device with a special structure in this utility model can be set on the lower side of the corresponding photovoltaic panel, thereby reducing the vertical space occupied by the wind power generation device to the greatest extent, which is conducive to reducing the height of the whole machine and making it convenient to use in some occasions where the size of the equipment is limited.

Detailed Implementation

[0037] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0038] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0039] An example of an implementation of a wind power and photovoltaic combined power generation system of this utility model is shown below. Figures 1-5 As shown: It includes multiple power generation units 1 arranged at intervals along the front-to-back direction. Each power generation unit includes a system support. A set of photovoltaic panels 2 (solar panels) extending along the left-to-right direction are installed on the system support, with the sun-facing side of the photovoltaic panels facing forward.

[0040] The system support also includes a wind power generation device located below the photovoltaic panels. The wind power generation device includes a wind turbine shaft 3 with its axis extending laterally. A power generation mechanism is connected to the wind turbine shaft, including a gearbox 10 that is driven by the wind turbine shaft. A generator is connected to the gearbox 10. Multiple wind-blocking blades 5 are fixed to the wind turbine shaft at circumferential intervals, with no fewer than eight blades. The length of each wind-blocking blade extends laterally, and both sides of the blades are arc-shaped surfaces with their axes extending forward and backward. The thickness of the wind-blocking blades gradually increases away from the wind turbine shaft axis. A blade flow channel is formed between two adjacent wind-blocking blades in the circumferential direction, gradually narrowing from the outside to the inside. Blade end plates 4 are fixed to both ends of the wind-blocking blades in the axial direction to increase their structural strength. In other embodiments of this invention, the gearbox may be omitted, in which case the wind turbine shaft can be directly connected to the generator.

[0041] The system support is equipped with an air guide device 6, which is used to guide the air to blow towards the wind deflector blades so that the wind turbine shaft rotates. In this embodiment, each wind turbine shaft corresponds to two air guide devices, and the two air guide devices are arranged sequentially along the axial direction of the wind turbine shaft. The air guide device includes a movable air guide cover 7 and a fixed wind deflector 8 arranged vertically. The fixed wind deflector has a fixed wind deflector guide channel for guiding the air to the corresponding wind deflector blade. The fixed wind deflector guide channel bends forward from top to bottom towards the corresponding wind deflector blade, and the size of the fixed wind deflector channel gradually narrows from top to bottom. The channel opening of the fixed wind deflector guide channel corresponds to four wind deflector blades.

[0042] The movable air guide 7 is rotatably mounted on the upper end of the fixed air baffle 8. The inner cavity of the movable air guide 7 is connected to the inner cavity of the fixed air guide 8. The rotation axis of the movable air guide 7 extends vertically. The side of the movable air guide 7 has an air inlet 9 located on the upper side of the corresponding photovoltaic panel. The movable air guide 7 is provided with a wind direction indicator structure for adjusting the rotation of the movable air guide 7 according to the wind direction. In this utility model, the wind direction indicator structure is a wind direction indicator fixed to the top of the movable air guide 7. When the wind blows, the wind direction indicator structure is subjected to the wind force, causing the movable air guide 7 to rotate, so that the air inlet of the air guide 7 always faces the direction of the wind. Of course, in other embodiments of this utility model, the wind direction indicator structure may not be provided. In this case, a baffle drive motor connected to the movable air guide 7 is required. When the wind direction changes, the baffle drive motor can drive the movable air guide 7 to rotate around its own axis, so that the air inlet of the air guide 7 always faces the direction of the downwind.

[0043] In this embodiment, the movable wind guide 7 is made of transparent material, so the movable wind guide will not affect the power generation of the photovoltaic panel of the rear power generation unit. The wind turbine shaft and wind deflector blades are completely hidden under the photovoltaic panel and will not occupy any height space. The photovoltaic panel generates electricity normally during the day. When there is wind, the movable wind guide 7 will rotate according to the wind direction to ensure that the air inlet of the wind guide 7 always faces the wind direction. The movable wind guide 7 directs the incoming wind to the fixed wind guide 7, and the fixed wind guide 7 directs the incoming wind to the corresponding wind deflector blades. The wind pushes the wind deflector blades, and the wind deflector blades rotate clockwise with the wind turbine shaft, thereby realizing power generation.

[0044] The overall height of the power generation system in this invention is relatively low, making it suitable for use on rooftops of residential buildings, factory rooftops, and hillsides.

[0045] Example 2 of a combined wind and photovoltaic power generation system Figure 6 As shown: The difference between Embodiment 2 and Embodiment 1 is that each power generation unit 1 is arranged in a vertical sequence.

[0046] Example 3 of a combined wind and photovoltaic power generation system Figures 7-9 As shown: The difference between Example 3 and Example 1 is that in this example, the wind power generation device adopts the second type.

[0047] The wind power generation device includes a first drive wheel 12 and a second drive wheel 13 whose axes extend in the front-rear direction. A circulating drive component 14 is wound around the first drive wheel 12 and the second drive wheel 13. The circulating drive component is a circulating drive belt (or chain plate). Multiple wind-blocking blades 5 are arranged circumferentially at intervals on the circulating drive component. The wind-blocking blades have a bucket-shaped structure. A gearbox is connected to the second drive wheel. A generator is connected to the gearbox. A wind guide device is installed on the system support. The wind guide device is used to guide the wind to blow towards the wind-blocking blades so that the circulating drive component rotates.

[0048] There are two air guiding devices, arranged sequentially in a left-right direction. Each device includes a fixed air guiding hood 8 and a movable windbreak hood 7 located above the fixed air guiding hood. The rotation axis of the movable windbreak hood 7 extends vertically. The air guiding hood outlet of the fixed air guiding hood 8 bends to the right, and the outlet of the fixed air guiding hood corresponds to three wind-blocking blades. An air inlet is located on the side of the movable air guiding hood, above the photovoltaic panel, and a wind direction indicator structure is provided on the movable air guiding hood.

[0049] In this embodiment, the entire wind power generation device is still completely hidden under the corresponding photovoltaic panel. When there is wind, the wind guide device directs the wind to the wind-blocking blades of the bucket-shaped structure, thereby driving the entire circulating transmission component to rotate. The circulating transmission component drives the first transmission wheel and the second transmission wheel to rotate, thereby realizing power generation.

[0050] Example 4 of a combined wind and photovoltaic power generation system Figures 11-12 As shown: It includes a system support 18, on which multiple sets of photovoltaic panels 2 are arranged at intervals in the vertical direction, with the sun-facing side of the photovoltaic panels facing forward. The system support is also equipped with a wind power generation device located on the lower side of the corresponding set of photovoltaic panels. The wind power generation device includes a wind turbine shaft 3 with its axis extending in the horizontal direction. A gearbox is connected to the wind turbine shaft, and a generator is connected to the gearbox. Multiple wind deflector blades 5 are fixed on the wind turbine shaft at intervals in the circumferential direction. The system support is equipped with a wind guide device, which is used to guide the wind to blow towards the wind deflector blades, thereby causing the wind turbine shaft to rotate.

[0051] Two adjacent sets of photovoltaic panels in the vertical direction are defined as upper photovoltaic panel 19 and lower photovoltaic panel 20. The air guiding device includes upper air guide shroud 16 and lower air guide shroud 17. The upper air guide shroud 16 guides the air to the wind deflector blades on the upper side of the wind turbine shaft from back to front; the lower air guide shroud 17 guides the air to the wind deflector blades on the lower side of the wind turbine shaft from front to back. The upper and lower air guide shrouds are located between two adjacent sets of photovoltaic panels in the vertical direction. The air intake directions of the upper and lower air guide shrouds are opposite. In this embodiment, the air intake direction of the upper air guide shroud is rearward, and the air intake direction of the lower air guide shroud is forward.

[0052] The size of the air guide channel in the upper air guide shroud gradually decreases from back to front, and the size of the air guide channel in the lower air guide shroud gradually decreases from front to back. The air guide channel of the upper air guide shroud is formed by the bottom of the upper air guide shroud and the upper photovoltaic panel, and the air guide channel of the lower air guide shroud is formed by the bottom of the lower air guide shroud and the lower photovoltaic panel.

[0053] Both the upper and lower wind deflectors are made of transparent material. The air outlet of the upper wind deflector corresponds to multiple wind deflectors on the upper side of the drive wheel, and the air outlet of the lower wind deflector corresponds to multiple wind deflectors on the lower side of the drive wheel. When the wind blows from back to front, the air is guided by the upper wind deflector to the corresponding wind deflectors, causing the drive wheel to rotate and generate electricity. When the wind blows from front to back, the air is guided by the lower wind deflector to the corresponding wind deflectors, causing the drive wheel to rotate and generate electricity. When the wind blows from left to right, the wind power generation device does not operate.

[0054] Example 5 of a combined wind and photovoltaic power generation system Figure 13 As shown: Example 5 differs from Example 4 in that the upper air guide shroud 16 is independently set with the upper photovoltaic panel, and the lower air guide shroud 17 is independently set with the lower photovoltaic panel. The center of gravity of the upper air guide shroud is located above the center of gravity of the lower air guide shroud. The overall height of the upper air guide shroud 16 and the lower air guide shroud 17 is the same. The upper wall of the upper air guide shroud is a planar structure, and the lower wall of the upper air guide shroud is an arc-shaped structure; the upper wall of the lower air guide shroud is an arc-shaped structure, and the lower wall of the lower air guide shroud is a planar structure.

[0055] Example 6 of a combined wind and photovoltaic power generation system Figure 14 As shown: The difference between Embodiment 6 and Embodiment 5 is that the upper air guide shroud 16 adopts the same matching structure as the upper air guide shroud and upper photovoltaic panel in Embodiment 4.

[0056] Example 7 of a combined wind and photovoltaic power generation system Figure 15 As shown: The difference between Embodiment 7 and Embodiment 5 is that the upper air guide shroud 16 is located at the rear end of the corresponding photovoltaic panel. After the wind is guided by the photovoltaic panel, it enters the upper air guide shroud 16. The air intake direction of the upper air guide shroud is forward, and the air intake direction of the lower air guide shroud 16 is backward. The lowest position of the wind deflector blade 5 is not lower than the lowest position of the corresponding photovoltaic panel.

[0057] Example 8 of a combined wind and photovoltaic power generation system Figure 16 As shown: In this embodiment, the system support is provided with an upper photovoltaic panel 19 and a lower photovoltaic panel 20 arranged at intervals. A wind power generation device is arranged between the upper and lower photovoltaic panels. The wind power generation device includes a first transmission wheel 12 and a second transmission wheel 13 arranged at intervals. The axes of the first transmission wheel 12 and the second transmission wheel 13 extend in the left and right direction. A circulating transmission component 14 is wound around the first transmission wheel 12 and the second transmission wheel 13. A gearbox is connected to the second transmission wheel, and a generator is connected to the gearbox.

[0058] The circulating transmission component is equipped with multiple bucket-shaped wind-blocking blades 5, and the system support is equipped with an air guiding device. The air guiding device is used to guide the wind to blow towards the wind-blocking blades, causing the circulating transmission component to rotate. The air guiding device includes two front air guiding hoods 21 distributed on the front side of the circulating transmission component and two rear air guiding hoods 22 distributed on the rear side of the circulating transmission component. There are two front air guiding hoods 21 arranged vertically, and two rear air guiding hoods 22 arranged vertically. The air intake direction of the front air guiding hoods is forward, and the air intake direction of the rear air guiding hoods is backward. When the wind blows from front to back, the front air guiding hoods guide the incoming air to the corresponding wind-blocking blades, and the circulating transmission component can rotate clockwise, thereby realizing wind power generation; when the wind blows from back to front, the rear air guiding hoods guide the incoming air to the corresponding wind-blocking blades, and the circulating transmission component can rotate clockwise, thereby realizing wind power generation.
