Description

Technical Field

[0001] This invention relates to the field of new energy technology, and more specifically, to a modular array-type wind and solar power generation corridor. Background Technology

[0002] Traditional large-scale wind turbine generators have high infrastructure costs and stringent site requirements. Blade recycling can easily generate secondary pollution, and the utilization rate of land near the wind farm is low. Photovoltaic power generation can only operate during the day and has a single form of energy utilization. Therefore, integrated wind and solar power equipment is adopted to make full use of energy.

[0003] Chinese patent CN103856151A discloses a long corridor-style road wind and solar energy composite power system. The station utilizes a steel frame platform capable of bearing weight and spanning ground structures to construct solar photovoltaic power stations and wind farms. This aims to fully utilize the abundant solar and wind energy generated by idle permanent ground structures such as roads. The platform is mainly supported by wind turbine towers, supplemented by steel beams and columns, and is assembled and fixed together. Multiple adjacent steel frame platforms together form a corridor-shaped steel frame platform. Solar photovoltaic module arrays are installed on the steel frame platform, and small and medium-sized wind turbines are installed on the towers.

[0004] However, the above structure has the following problems: 1. The gap between the wind turbine units is large, the airflow escapes seriously, and it is impossible to form a continuous wind capture effect. Each wind turbine operates independently and there is no mutual utilization of airflow or wind supplementation between adjacent units. The wind capture range is narrow and the wind energy utilization rate is low. The wind direction adaptability is poor. When the wind direction deviates from the wind turbine axis, the power generation efficiency drops significantly and the power generation stability is poor in the environment with changing wind direction.

[0005] 2. The fan unit is large in size, occupies a lot of space, has poor environmental adaptability, is limited in the suitable site, and is not convenient for maintenance and replacement.

[0006] 3. The low-altitude area of ​​2-12m above the ground has been idle for a long time, and a large amount of low-altitude wind energy and land resources cannot be developed and utilized, resulting in a low comprehensive land utilization rate. Summary of the Invention

[0007] To overcome the above-mentioned defects of the prior art, the present invention provides the following technical solution: a modular array-type wind and solar power generation corridor, comprising multiple power generation modules, wherein each power generation module includes a frame and a photovoltaic panel set on the top of the frame. The power generation modules are arranged according to the terrain and two adjacent power generation modules are connected end to end. The special feature is that multiple wind power generation units are arranged in an array on both sides along the direction of terrain extension in each frame, and the adjacent wind power generation units are closed at the adjacent points.

[0008] As a further preferred embodiment of the present invention, the power generation module includes a vertical axis power generation module and / or a horizontal axis power generation module, and the wind power generation unit includes a horizontal axis unit and / or a vertical axis unit; the vertical axis power generation module is arranged in curved terrain and / or straight terrain, and the horizontal axis power generation module is arranged in straight terrain; the horizontal axis power generation module includes a horizontal axis unit; multiple horizontal axis units are arranged in an array, adjacent horizontal axis units are fixedly connected, and the adjacent parts are closed; the vertical axis power generation module includes a vertical axis unit; adjacent vertical axis units are fixedly connected in the longitudinal direction, and the adjacent parts of the lateral outer edges of adjacent vertical axis units are closed. The above structural configuration provides a selectable structure for power generation modules and wind power generation units adapted to different terrains.

[0009] As a further preferred embodiment of the present invention, the frame includes a crossbeam, columns, and support columns; there are multiple columns arranged on both sides along the direction of terrain extension, and an array of wind power generation units is arranged between adjacent columns on the same side; the crossbeam is fixed above the columns and spans across the columns on both sides; the upper surface of the crossbeam is inclined to one side or protrudes in the middle and is inclined to both sides, and a photovoltaic panel is arranged above the crossbeam; the top and bottom of the array of wind power generation units are fixed with connecting frames, and the two ends of the connecting frames are fixedly connected to the columns on both sides, thereby providing support for the wind power generation units through the above structure.

[0010] As a further preferred embodiment of the present invention, the horizontal axis unit includes a wind-gathering cavity, a horizontal axis support frame, a horizontal axis fan, and a horizontal axis generator. A connecting ring is provided on the outer side of the horizontal axis generator. There are two wind-gathering cavities, which are trumpet-shaped and are respectively fixed to the front and rear sides of the connecting ring and are symmetrically arranged. The outer cavity surface of the wind-gathering cavity is engaged with the inner side of the frame on the front and rear sides of the horizontal axis support frame, and the two wind-gathering cavities abut against the front and rear sides of the horizontal axis support frame along their edges. A coaxial horizontal axis fan is installed on the front and rear sides of the horizontal axis generator. The horizontal axis fan is located at the central opening of the wind-gathering cavity. Through the above arrangement, the horizontal axis wind power generation units are closely connected to form a wide-area wind capture.

[0011] As a further preferred embodiment of the present invention, air guide plates are fixed on the front and rear sides between two adjacent sets of longitudinally connected horizontal axis units and between adjacent horizontal axis units and columns. The air guide plates are vertically arranged and include fixed connection holes, pressure strips, and air guide plate surfaces. The pressure strips are arranged on both sides of the air guide plate surface to assist in air guiding. The bottoms of the two sets of pressure strips on the front and rear sides respectively abut against the outer edge of the corresponding side air-gathering cavity for auxiliary fixation. The fixed connection holes are inserted between two adjacent sets of longitudinally connected horizontal axis units and between adjacent horizontal axis units and columns, and are fixedly connected. The air guide plate surface is arranged facing away from the side of the horizontal axis unit. The horizontal axis unit is provided with a double-sided symmetrical trumpet-shaped closed air-gathering cavity. With the outer vertical air guide plate, it can simultaneously gather the main airflow on the front and the scattered airflow on both sides, and concentrate it into the cavity to drive the wind blades to generate electricity, resulting in a stronger wind gathering effect.

[0012] As a further preferred embodiment of the present invention, the vertical shaft unit includes a connecting top cover, an upper vertical shaft generator, a vertical shaft support frame, a fan shaft, a lower vertical shaft generator, a connecting base plate, and vertical shaft blades; the connecting top cover and the connecting base plate are located at the upper and lower ends of the vertical shaft unit and are fixedly connected by the vertical shaft support frame, and both the connecting top cover and the connecting base plate are provided with corresponding bolt holes; the upper vertical shaft generator is fixedly connected to the bottom of the connecting top cover, and the lower vertical shaft generator is fixed to the upper part of the connecting base plate, and the upper vertical shaft generator and the lower vertical shaft generator are coaxially arranged; The top end of the fan blade shaft is keyed to the upper vertical shaft generator, and the bottom end of the fan blade shaft is keyed to the lower vertical shaft generator. The fan blade shaft is axially slidably connected between the upper and lower vertical shaft generators. The vertical shaft blades are evenly distributed around the outside of the fan blade shaft. The vertical shaft blades are curved arc-shaped blades that can only rotate unidirectionally in a set direction under the action of wind force. The axial driving force generated by this rotation is upward, and the vertical shaft blades are located inside the vertical shaft support frame. Through the above settings, when the airflow rises, it causes the vertical shaft blades and the fan blade shaft to float independently, reducing the impact of axial load on the power generation module shaft, greatly reducing bearing friction loss, and extending the service life of the whole machine.

[0013] As a further preferred embodiment of the present invention, vertically arranged and outwardly radiating wind-catching plates are fixedly connected to the outer side of the vertical shaft support frame. There are multiple wind-catching plates, which are evenly distributed around the outer side of the vertical shaft support frame. The horizontal cross-section of any wind-catching plate is perpendicular to the annular surface of the vertical shaft support frame or is inclined at the same angle to the tangent of the annular surface of the vertical shaft support frame. The outer edges of adjacent vertical shaft units are staggered, and the edges of the nearest wind-catching plates of two horizontally adjacent vertical shaft units are in contact and closed. The arrangement of the wind-catching plates achieves all-round wind capture. The above arrangement enables the vertical shaft units to be compactly placed, and the annular wind guide frames of adjacent units cooperate with each other to achieve wind collection throughout the entire corridor, thereby improving wind capture efficiency.

[0014] As a further preferred embodiment of the present invention, the fan blade shaft includes a shaft top spline located at the top of the fan blade shaft and a connecting key sleeve located at the bottom of the fan blade shaft. The receiving end at the top of the lower vertical shaft generator is a connecting spline, which is inserted into the connecting key sleeve with a clearance fit, and the connecting key sleeve covers the connecting spline. The shaft top spline is inserted into the receiving end at the top of the upper vertical shaft generator with a clearance fit, and the receiving end at the top of the upper vertical shaft generator covers the shaft top spline. By providing an integrally formed spline combination at the upper and lower ends of the fan blade shaft, and cooperating with the downward-facing inverted covering of the connecting spline, rainwater is effectively prevented from seeping into the gaps and accumulating rust, improving the waterproof and durability performance of outdoor equipment, and the clearance fit ensures that its sliding is not affected.

[0015] As a further preferred embodiment of the present invention, a horizontal axis light ring is fixed on the inner ring side of the connecting ring surface on the outer side of the horizontal axis generator; vertical axis light rings are fixed on opposite sides of the upper and lower vertical axis support frames to provide supplementary lighting for the corridor and enhance the atmosphere and landscape effect.

[0016] As a further preferred embodiment of the present invention, the bottom of the array of the wind power generation unit is 2-2.5m above the terrain, and the top of the array of the wind power generation unit is 6-12m above the terrain. By setting the bottom height above the ground, it is possible to prevent personnel from accidentally touching the rotating blades, avoid the safety hazard of mechanical scratches, and improve safety. By setting the top height above the ground, it can be adapted to the required environment and achieve the wind capture effect.

[0017] The beneficial effects of this invention are: 1. This invention adopts a modular structure that can be continuously spliced ​​and extended. The width of each module is optional, and the connection position is adapted to the terrain elevation and angle. It is suitable for various long and continuous sites such as highways, farmland, parks, and wind farms, and has a wide range of applications. 2. The wind power generation unit array is arranged with the wind guide structure of adjacent units working together to form a wind supplement effect, which greatly reduces the escape of airflow from the gaps between the units. The entire corridor achieves continuous wind capture and significantly improves the utilization rate of wind energy.

[0018] 3. Modular wind power generation units are adopted, which are small in size, easy to assemble and construct, and can replace damaged units individually in the later stage, resulting in low operation and maintenance costs; the components are disassembled and recyclable, making them green and environmentally friendly, and enabling large-scale long-distance deployment.

[0019] 4. The low-altitude wind energy is fully utilized, and land resources are fully utilized through the corridor-style design, resulting in a high comprehensive land utilization rate. Attached Figure Description

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1 like Figure 1-3 As shown, a modular array-type wind and solar power generation corridor includes multiple power generation modules. Each power generation module includes a frame and a photovoltaic panel 5 installed on the top of the frame. The power generation modules are arranged according to the terrain, and two adjacent power generation modules are connected end to end. In each frame, multiple wind power generation units are arranged in an array on both sides along the direction of terrain extension, and the adjacent wind power generation units are closed off.

[0033] The power generation module includes a vertical axis power generation module 2 and / or a horizontal axis power generation module 1, and the wind power generation unit includes a horizontal axis unit 3 and / or a vertical axis unit 4; the vertical axis power generation module 2 is arranged in curved terrain and / or straight terrain, and the horizontal axis power generation module 1 is arranged in straight terrain; the horizontal axis power generation module 1 includes a horizontal axis unit 3; multiple horizontal axis units 3 are arranged in an array, adjacent horizontal axis units 3 are fixedly connected, and the adjacent parts are closed; the vertical axis power generation module 2 includes a vertical axis unit 4; adjacent vertical axis units 4 are fixedly connected in the longitudinal direction, and the adjacent parts of the lateral outer edges of adjacent vertical axis units 4 are closed.

[0034] In this embodiment, the vertical staggered arrangement of adjacent vertical axis units 4 or horizontal axis units 3 is used to adapt to undulating roads.

[0035] like Figure 4-6As shown, in this embodiment, to improve the wind capture of the vertical shaft unit 4 and reduce the impact of axial load on the rotating shaft of the power generation module, as well as to reduce rainwater corrosion, the vertical shaft unit 4 includes a connecting top cover 401, an upper vertical shaft generator 402, a vertical shaft support frame 403, a wind turbine shaft 406, a lower vertical shaft generator 408, a connecting base plate 409, and vertical shaft blades 410; the connecting top cover 401 and the connecting base plate 409 are located at the upper and lower ends of the vertical shaft unit 4 and are fixedly connected by the vertical shaft support frame 403, and both the connecting top cover 401 and the connecting base plate 409 are... The upper vertical shaft generator 402 is fixedly connected to the bottom of the connecting top cover 401, and the lower vertical shaft generator 408 is fixed to the upper part of the connecting base plate 409. The upper vertical shaft generator 402 and the lower vertical shaft generator 408 are coaxially arranged. The top end of the fan blade shaft 406 is keyed to the upper vertical shaft generator 402, and the bottom end of the fan blade shaft 406 is keyed to the lower vertical shaft generator 408. The fan blade shaft 406 is axially slidably connected between the upper vertical shaft generator 402 and the lower vertical shaft generator 408. The vertical shaft blades... 410 blades are evenly distributed around the outside of the wind turbine shaft 406. The vertical shaft blades 410 are curved arc-shaped blades that can only rotate unidirectionally in a set direction under wind force, and the axial driving force generated by this rotation is upward. The vertical shaft blades 410 are located inside the vertical shaft support frame 403. The wind turbine shaft 406 includes a shaft top spline 405 at the top of the wind turbine shaft 406 and a connecting key sleeve 407 at the bottom of the wind turbine shaft 406. The wind turbine shaft 406 is integrally formed. The receiving end at the top of the lower vertical shaft generator 408 is a connecting spline 4081. Spline 4081 is inserted into connecting key sleeve 407 with clearance fit, and connecting key sleeve 407 covers connecting spline 4081; shaft top spline 405 is inserted into the receiving end at the top of upper vertical shaft generator 402 with clearance fit, and receiving end at the top of upper vertical shaft generator 402 covers shaft top spline 405. During the up and down floating of fan shaft 406, connecting spline 4081 and top spline do not detach from key sleeve to ensure coverage. Lubricating grease can be added to the gap to improve floating flexibility and further improve wear and rust prevention effect.

[0036] like Figure 7-8As shown, in this embodiment, to improve the wind-catching effect of the horizontal axis unit 3, the horizontal axis unit 3 includes a wind-gathering cavity 301, a horizontal axis support frame 302, a horizontal axis fan 303, and a horizontal axis generator 304. The horizontal axis generator 304 has a connecting ring on its outer side. There are two wind-gathering cavities 301, which are horn-shaped and are fixed to the front and rear sides of the connecting ring and are symmetrically arranged. The outer cavity surface of the wind-gathering cavity 301 is engaged with the inner side of the frame of the front and rear sides of the horizontal axis support frame 302, and the edges of the two wind-gathering cavities 301 abut against the front and rear sides of the horizontal axis support frame 302, respectively. The horizontal axis generator 304 is equipped with a coaxial horizontal axis fan 303 on its front and rear sides. The horizontal axis fan 303 is located in the middle of the horn-shaped opening of the wind-gathering cavity 301.

[0037] like Figure 3 , Figure 9 and Figure 10 As shown, in this embodiment, to improve the wind-catching effect of the horizontal axis unit 3, air guide plates 6 are fixed on the front and rear sides between two adjacent sets of longitudinally connected horizontal axis units 3 and between adjacent horizontal axis units 3 and the column 11. The air guide plates 6 are vertically arranged and include fixed connection holes 601, pressure strips 602 and air guide plate surfaces 603. The pressure strips 602 are arranged on both sides of the air guide plate surface 603 to assist in air guiding. The bottoms of the two sets of pressure strips 602 on the front and rear sides respectively abut against the outer edge of the corresponding side air-gathering cavity for auxiliary fixation. The fixed connection holes 601 are inserted between two adjacent sets of longitudinally connected horizontal axis units 3 and between adjacent horizontal axis units 3 and the column 11 and are fixedly connected. The air guide plate surface 603 is arranged facing away from the horizontal axis unit 3. The air guide plate 603 and the pressure strip 602 can converge the air coming from the front and side into the horn cavity, causing the fan blades to rotate in the forward direction; the air coming from the back is also converged by the rear air guide plate and pressure strip and introduced into the horn cavity, causing the fan blades to rotate in the reverse direction to generate electricity.

[0038] like Figure 4-5 As shown, in this embodiment, to improve the wind-catching effect of the vertical shaft unit 4, vertically arranged and outwardly radiating wind-catching plates 404 are fixedly connected to the outside of the vertical shaft support frame 403. There are multiple wind-catching plates 404, which are evenly distributed around the outside of the vertical shaft support frame 403. The horizontal cross-section of any wind-catching plate 404 is perpendicular to the ring surface of the vertical shaft support frame 403 or is inclined at the same angle as the tangent of the ring surface of the vertical shaft support frame 403. Two horizontally adjacent wind-catching plates 404 of the vertical shaft unit 4 are in contact and closed, and the contact line is located at a depth of 2mm at the wind-catching plate 404.

[0039] For winds coming from the sides at both ends of a modular array-type wind and solar power generation corridor, the wind will enter through the corridor openings at both ends to form a narrow tube effect, blowing towards the power generation units on both sides to make the wind blades rotate and generate electricity, thus achieving multi-directional wind power generation.

[0040] Example 2 like Figure 1 As shown in the first embodiment, in this embodiment, the modular array-type wind and solar power generation corridor is arranged on various trunk roads such as highways, national highways, and provincial highways. Because the roadside is a naturally long, linear, idle space with continuous and stable low-altitude wind and sunshine resources, the entire structure is elevated across the road surface through a cross-road structure. The two side columns 11 are fixed to the road shoulders, and the entire structure does not occupy the driving lanes, thus not interfering with vehicle traffic or road maintenance work. The low-power LED lights in the horizontal and vertical axis power generation units provide diffused light, serving as auxiliary lighting and landscape embellishment functions without interfering with the driver's vision. The total width of the two-way four-lane road surface is 15m, and the overall span is relatively small. like Figure 1-3 As shown, in this embodiment, a horizontal axis power generation module 1 is used at straight sections of the road, and a vertical axis power generation module 2 is used at curved sections. The frame includes a crossbeam 10, columns 11, and support columns 8. There are four columns 11, arranged in pairs along the direction of the terrain, and an array of wind power generation units is set between adjacent columns 11 on the same side. The crossbeam 10 is fixed above the columns 11 and spans across the columns 11 on both sides. The upper surface of the crossbeam 10 is inclined to one side or protrudes in the middle and is inclined to both sides. Connecting frames 7 are fixed at the top and bottom of the array of wind power generation units. The two ends of the connecting frames 7 are fixedly connected to the columns 11 on both sides and are located at the bottom. The bottom of the connecting frame 7 is fixed with multiple support columns 8, and the bottom of the support columns 8 is fixed to the terrain; multiple purlins 9 are fixed on the upper surface of the crossbeam 10, and the upper surface of the purlins 9 is set with the upper surface of the crossbeam 10, and the purlins 9 and the crossbeam 10 are arranged perpendicularly. The photovoltaic panel 5 is fixed to the upper surface of the purlins 9; the foundation of the column 11 is pre-embedded with M24 anchor bolts; the splicing node between the crossbeam 10 I-beam and the column 11 uses double-row M14 bolts; the crossbeam 10 and the purlins 9 are connected with M12 bolts; adjacent wind power generation units are fixed with M8 bolts at the connection points. All load-bearing components are made of 8.8 grade hot-dip galvanized material and equipped with anti-loosening structure.

[0041] A drainage pipe 12 is installed at the lower inclined end of the photovoltaic panel 5, running along both sides of the entire power generation corridor in the actual scenario. This is a conventional component that is only found at certain locations. Figure 3 The diagram is shown below; common settings will not be described in detail.

[0042] Furthermore, when the road is a two-way six-lane highway with a road surface width of 22.5m, it can be erected by relying solely on the two-sided columns 11, but the crossbeams 10 profiles need to be thickened, resulting in higher steel input costs. When the road surface width of an eight-lane highway reaches more than 30m, the lateral span is too large, and the cantilever structure with only the two-sided columns 11 is prone to continuous wind vibration and structural deformation.

[0043] In this embodiment, a central reinforcing column needs to be added to the median strip of the road. The reinforcing column is supported below the center of the crossbeam. The two side columns 11, together with the reinforcing column, form a composite load-bearing structure, and the span of a single crossbeam 10 is shortened to improve the overall wind resistance stability of the structure. The crossbeam 10 is connected in two sections by bolts. For the sake of aesthetics and power generation efficiency, the modular array-type wind and solar power generation corridor has a small-angle herringbone symmetrical arrangement of the top solar photovoltaic panels. The bottom of the connecting frame 7 at the bottom is fixed with two support columns 8. The bottom of the support columns 8 is fixed to the terrain and can be set with the same specifications as the columns 11.

[0044] In windless weather, vehicles traveling through the modular array-type wind and solar power generation corridor will generate positive pressure windward airflow at the front of the vehicle and negative pressure tailflow at the rear, which will directly blow onto the horizontal or vertical axis power generation units on both sides to generate electricity. This is also the special function of the modular array-type wind and solar power generation corridor that makes it suitable for various types of highways.

[0045] With the above configuration, in this embodiment, the modular array-type wind and solar power generation corridor is continuously arranged along the road to form a complete wind wall. The top of the array of wind power generation units is 9m above the terrain. Relying on the road space and traffic flow, the wind energy capture efficiency is further improved. The power generated by the corridor wind and solar complementary power generation system is given priority to road monitoring, lighting and other public facilities, and the remaining surplus power is connected to the national public power grid.

[0046] Example 3 Based on the first embodiment, in this embodiment, the modular array-type wind and solar power generation corridor is suitable for replacing existing windbreaks in farmland. Currently, high-standard farmland in China generally uses arbor windbreaks to achieve soil stabilization and wind protection. According to farmland construction specifications, the main windbreak belt of farmland is typically 8-10m wide, and fast-growing poplar trees are mostly selected as vegetation. Traditional arbor windbreaks have obvious drawbacks: the trees have extensive root systems, which continuously deprive the surrounding farmland of water and nutrients, resulting in reduced crop yields on both sides of the forest belt; the mature trees can reach a height of 12-18m, and the dense canopy blocks sunlight from the fields for a long time, shortening the photosynthetic time of crops; the annual maintenance cost of the trees is high, pests and diseases occur frequently, and they cannot be flexibly adjusted or removed according to the farmland cultivation cycle. The modular array-type wind and solar power generation corridor occupies only 5-6m in width, which greatly saves farmland resources. like Figure 5 , Figure 6 and Figure 8As shown, in this embodiment, a horizontal axis light ring 305 is fixed on the inner ring side of the connecting ring surface on the outer side of the horizontal axis generator 304; vertical axis light rings 411 are fixed on opposite sides of the upper and lower vertical axis support frames 403. The dual-mode low-power LED lighting components of the horizontal axis light ring 305 and the vertical axis light ring 411 are low-power soft light, using diffused light, and only used for environmental outline lighting, serving as decoration, warning, and walkway lighting. They can be automatically turned on by light sensing or remotely turned on. This is existing technology and will not be described in detail here. Its setting takes into account the functions of lighting, warning, and landscape lighting.

[0047] In this embodiment, to enhance the power generation efficiency of the solar photovoltaic panels, the wind guide plate is tilted to the south (Northern Hemisphere), with an angle of ≤25° in low latitude regions, 26° to 40° in mid-latitude regions, and ≥40° in high latitude regions. To ensure safety, the bottom of the wind power generation unit array is 2.5m above the terrain, and to ensure wind protection height and effectiveness, the top of the wind power generation unit array is 6m above the terrain.

[0048] In this embodiment, a continuous and complete windbreak can be formed during operation, solving the problem of reduced crop yields caused by tree shading and excessive fertilizer application. The electricity generated by wind and solar synergy can supply the daily electricity needs of surrounding villages and towns, farmland irrigation equipment, and field security monitoring equipment, simultaneously achieving the dual functions of farmland wind protection and local production of clean energy.

[0049] Example 4 Based on the first embodiment, in this embodiment, the modular array wind and solar power generation corridor is continuously laid along the main maintenance road of the wind farm, the wind turbine gap channel and the boundary of the field area. The core of the existing large onshore wind farm power generation relies on the hundred-meter-class high-altitude wind turbines. The ground and low-altitude areas have been idle for a long time, and a large amount of low-altitude wind energy and land resources cannot be developed and utilized, resulting in a low comprehensive land utilization rate. In this embodiment, to enhance the power generation efficiency of the solar photovoltaic panel, the wind guide plate of the photovoltaic panel is tilted to the south (Northern Hemisphere), ≤25° in low latitude regions, 26° to 40° in mid-latitude regions, and ≥40° in high latitude regions. The bottom of the array of the wind power generation unit is 2m above the terrain. To ensure wind protection height and effect, the top of the array of the wind power generation unit is 12m above the terrain. The horizontal axis unit 3 and the vertical axis unit 4 are easy to disassemble and assemble, reducing the installation intensity.

[0050] This will enable the combination of large high-altitude wind turbines with low-altitude corridors to form a high-low tiered power generation mode, significantly improving the power generation per unit area of ​​the wind farm and the overall operating income.

[0051] Each power generation module and photovoltaic panel 5 power generation module in the entire power generation corridor has a reserved independent power output interface. The output end is connected to the external power distribution component through cable. After conversion, the power is connected to the grid or stored. The power consumption method can be freely selected according to the actual operation needs. This is existing technology and will not be described in detail here.

[0052] The above description is merely a preferred embodiment of the present invention, and its application scope is wide. It is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
