DETAILED DESCRIPTION

[0042] In order to make the objects, technical solutions, and advantages of the present application clearer, the following will be combined with the accompanying drawings and specific embodiments to make a detailed description. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a variety of ways other than those described herein without departing from the scope of the present application, and those skilled in the art can make similar improvements without departing from the concept of the present application, so the present application is not limited to the specific implementation disclosed below.

[0043] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is referred to as being "connected" to another element, it can be directly connected to the element or there can be an intermediate element. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0045] The embodiment provides a photovoltaic module matrix structure with a 10° inclination, and the structure is as shown in the figure. Figure 1As shown, there are two types of module groups, namely an east-west module group 1 distributed in the east-west direction and a north-south module group 2 arranged in the north-south direction.

[0046] Because matrix structures are mostly located in the Northern Hemisphere, the module groups are divided into two types to allow for selection based on latitude. In lower latitudes, choosing an east-west distribution of modules aligns with the sun's rising and setting trajectory, improving the PV module matrix's absorption of solar energy. In higher latitudes, where sunlight shines obliquely, choosing a north-south distribution of modules can increase daily absorption of solar energy and optimize solar energy utilization.

[0047] like Figures 1 to 3 As shown, both the east-west module group 1 and the north-south module group 2 include a base 3, photovoltaic panels 4, front and rear legs 5, and ballast 6. The base 3 includes two parallel, blockless rails 31, which are fixed to the roof and used to connect to the roof's mounting surface and mount the module groups. The photovoltaic panels 4 are tilted and mounted on the base 3 to receive sunlight and collect solar energy.

[0048] The base 3 and photovoltaic panel 4 are connected by front and rear legs 5. These legs consist of front mounting legs 51 and rear mounting legs 52, fixed to either side of the base 3. The rear mounting legs 52 are taller than the front mounting legs 51, creating a height difference between the two. This serves to connect the base 3 and the photovoltaic panel 4 and ensure a 10° inclination angle relative to the mounting surface. To enhance the overall stability of the matrix structure, each base 3 is equipped with at least one ballast 6.

[0049] The difference between the east-west module group 1 and the north-south module group 2 is that the photovoltaic panels 4 of the east-west module group 1 are tilted towards the east and west respectively, forming an isosceles triangle structure with the base 3; while the photovoltaic panels 4 of the north-south module group 2 are all tilted towards the south, forming a right-angled triangle structure with the base 3.

[0050] Meanwhile, north-south windbreaks 11 are installed on the north-south opening of east-west module group 1 to seal the opening. East-west windbreaks 21 are installed on the east-west opening of north-south module group 2, and a north windbreak 22 is installed on the north side of north-south module group 2. The connection between two adjacent photovoltaic panels 4 in north-south module group 2 is fixed directly to the mounting surface via front and rear legs 5 and mounting brackets 53, without a base 3.

[0051] Since the present invention is mostly located in my country, southeast and southwest winds prevail in summer, and northwest and northeast winds prevail in winter. Generally speaking, the wind direction is east-west. Therefore, the east-west module group 1 is set to an isosceles triangle structure inclined in the east-west direction. The east-west wind can use the downward pressure on the photovoltaic panel 4 to improve the stability of the overall structure, and a north-south windbreak 11 is set on the north-south opening to prevent the north-south airflow from entering the east-west module group 1 and affecting the stable structure of the east-west module group 1.

[0052] Due to the inclination caused by the latitude factor, the north-south module group 2 needs to be tilted to form an inclined right-angled triangle structure, and the openings in other directions are closed by the east-west windbreak plate 21 and the north windbreak plate 22, which can prevent the north-south module group 2 from being overturned by excessive wind and improve the stability of the north-south module group 2.

[0053] like Figures 3 to 4 As shown, in order to further improve the windproof performance of the north-south module group 2, the north side windproof plate 22 in the present invention includes a top connecting plate 221, a middle windproof plate 222 and a bottom connecting plate 223 connected in sequence from top to bottom, and the top connecting plate 221 and the bottom connecting plate 223 are respectively fixed on the top and bottom of the front and rear feet 5.

[0054] The top connecting plate 221 has an arcuate cross-section. The middle windshield 222 is angled toward the photovoltaic panel 4 and connects to the bottom connecting plate 223 to form an inwardly sloping surface. An air inlet 23 is formed between the top connecting plate 221 and the photovoltaic panel 4, and an air outlet 24 is formed between the end of the photovoltaic panel 4 facing away from the north windshield 22 and the mounting surface.

[0055] As shown in the figure, after installing the inclined middle wind shield 222, the north wind blowing directly towards the north wind shield 22 is guided by the middle wind shield 222, forming an airflow that swirls toward the bottom and rear, which can partially offset the wind force from the rear and reduce the impact of the north wind on the north-south module group 2. Part of the airflow is guided by the curved top connecting plate 221, enters the module group through the air inlet 23, flows toward the photovoltaic panels 4, and finally exits through the air outlet 24 on the other side. This divides the north wind into several streams, reducing its impact on the stability of the north-south module group 2.

[0056] Furthermore, the mounting angle of the photovoltaic panels 4 is generally affected by local latitude and requires adjustment. However, due to the simple structure, low cost, and low weight of the photovoltaic module matrix in the present invention, excessively large angles can easily lead to reduced stability. Taking into account sunlight exposure conditions and wind influences, the present invention sets the mounting angle of the photovoltaic panels 4 at 10°. This ensures optimal solar energy utilization while maintaining optimal overall stability of the photovoltaic module matrix structure.

[0057] As Figures 4 to 9 shown, the base 3 is the basis of the entire module group, the base 3 includes a blockless guide rail 31 and a mounting seat 53, the mounting seat 53 is sleeved on both ends of the blockless guide rail 31, and is used for connecting a mounting front leg 51 and a mounting rear leg 52; the mounting seat 53 includes a mounting body 531, the mounting body 531 is hollowly formed with a mounting hole 533 matched in shape with the blockless guide rail 31, and the mounting body 531 is outwardly formed with an extension plate 532 abutting a mounting surface at both ends. The blockless guide rail 31 is hollowly provided with a drainage channel 311, and the blockless guide rail 31 is sleeved in the mounting hole 533.

[0058] The mounting body 531 is provided in a trapezoidal shape in cross section, one side of the mounting body 531 is formed with a fixing lug 534, a bolt is penetratingly arranged on the fixing lug 534, and the bolt is abutted against a side surface of the blockless guide rail 31 and is used for fastening the blockless guide rail 31. The mounting front leg 51 and the mounting rear leg 52 are each provided with a positioning plate 54 penetratingly arranged in the mounting seat 53, and the mounting body 531 is provided with a reinforcing protrusion 535 protruding inwardly on a top surface thereof, and the mounting front leg 51 and the mounting rear leg 52 are each fastened to the reinforcing protrusion 535 by a bolt.

[0059] The mounting body 531 is formed with a fixing opening 536 on a bottom surface thereof, and the mounting body 531 is fastened to a mounting surface by cooperation of the fixing opening 536 and a bolt. The mounting body 531 is formed with limiting strips 537 protruding towards a top portion on both sides of the top portion, and a spacing between the two limiting strips 537 is greater than a width of the mounting front leg 51 and the mounting rear leg 52. The blockless guide rail 31 is provided in a trapezoidal structure in overall cross section, with a width of a bottom portion being greater than a width of a top portion. Meanwhile, a stress groove 538 is formed in a middle position of the extension plate 532.

[0060] The blockless guide rail 31 is hollowly formed with the drainage channel 311, and water accumulation can be discharged through the drainage channels 311 on both sides after installation, so that the influence of water accumulation and snow accumulation on the service life of the module group is avoided. The stress groove 538 is formed in the extension plate 532, so that a certain deformation amount is provided when the module group shakes due to wind blowing, and cracking or deformation caused by the shaking is prevented.

[0061] In the application, the ballast 6 is arranged on each blockless guide rail 31 of the base 3 and includes a mounting frame 61 and cement blocks 62 arranged on the mounting frame 61. The mounting frame 61 is divided into a through frame 611 connecting two bases 3 and a split frame 612 arranged on each base 3. The through frame 611 is arranged at a middle position of the base 3, and the split frame 612 is symmetrically arranged on both sides of the through frame 611. Each split frame 612 is correspondingly provided with the cement blocks 62, and the through frame 611 is provided with a plurality of cement blocks 62 arranged at equal intervals.

[0062] In the north-south module group 2, only the ballast 6 with the split frame 612 structure is applied, while in the east-west module group 1, the through frame 611 is arranged at the middle position, and the split frame 612 is arranged on the block-free guide rail 31 on both sides. At the same time, the south-north windproof plate 11 and the east-west windproof plate 21 are both provided with a drainage and air outlet 12 and a through hole 13, and the ballast 6 is located in the through hole 13; the ballast 6 includes a mounting frame 61 arranged on the base 3 and a cement block 62 placed on the mounting frame 61.

[0063] The through frame 611 and the split frame 612 are distributed according to the above structure, because in the east-west module group, the south-north direction is only windproof by the south-north windproof plate 11, so when the south-north wind blows, the through frame 611 with greater weight is needed to ensure the stability of the overall structure. The drainage and air outlet 12 arranged at the same time can guide the wind and accumulated water into the module group out, avoiding affecting the overall stability and service life of the module group.

[0064] The split frame 612 includes two symmetrical angle steel strips 613, the top of the angle steel strip 613 forms a placement part abutting the cement block 62, used for placing the cement block 62; the end of the placement part on one side of the angle steel strip 613 is bent upward to form a limiting part 614 abutting the side surface of the cement block 62, and the spacing between the two limiting parts 614 is the same as the width of the cement block 62. The middle position of the angle steel strip 613 forms a mounting hole 615, and the base 3 is embedded in the mounting hole 615, and the lengths of the angle steel strips 613 on both sides of the mounting hole 615 are the same.

[0065] The cross section of the through frame 611 is in a U-shaped structure, and a placement area 616 is formed, the width of the placement area 616 is the same as the width of the cement block 62, and the height of the through frame 611 is greater than the height of the cement block 62. In addition, the two ends of the through frame 611 are provided with a drainage outlet 617 for releasing accumulated water.

[0066] The split frame 612 is directly embedded in the block-free guide rail 31, so the lengths of the angle steel strips 613 on both sides of the mounting hole 615 are the same, ensuring that the center of gravity is in the mounting hole 615 after the cement block 62 is installed, balancing the weight on both sides, and further improving the stability. The drainage outlets 617 arranged on both sides of the through frame 611 can drain the rain and snow water accumulated in the through frame 611, avoiding corrosion of the metal structure caused by accumulated water.

[0067] As Figures 7 to 8As shown, the front mounting leg 51 in the application comprises a front seat leg 511 fixed on the mounting seat 53, a side pressing block 512 for connecting the photovoltaic cell panel 4, and a side pressing block 513 for connecting the front seat leg 511 and the side pressing block 512; the rear mounting leg 52 comprises an integrally formed connecting bottom plate 521, a connecting top plate 522, and an intermediate connecting plate 523 for connecting the two; the connecting bottom plate 521 is fixed on the base 3, and the connecting top plate 522 is fixed opposite to the photovoltaic cell panel 4.

[0068] The intermediate connecting plate 523 is provided with two symmetrically arranged blocks, the two intermediate connecting plates 523 are arranged in an arc shape and are inclined towards the center line of the rear mounting leg 52, and a reinforcing plate 524 is arranged between the two intermediate connecting plates 523.

[0069] The connecting top plate 522 is in the shape of an upwardly convex arc, and the photovoltaic cell panels 4 on both sides are fixed on the top surface of the connecting top plate 522 through the side pressing block 512 and the side pressing block 513.

[0070] In addition, the front seat mounting frame 515 is hollow, and a stress connecting plate 516 is arranged therein, the stress connecting plate 516 is in the shape of a hollow cylinder formed by bending at the middle position, and a limiting plate 517 for limiting the position of the photovoltaic cell panel 4 is formed on the front seat mounting frame 515.

[0071] In the rear mounting leg 52, the intermediate connecting plate 523 is arranged in an arc shape, when the rear mounting leg 52 is pressed, the arc-shaped connecting plate can provide a certain buffer to avoid damage to the photovoltaic cell panel 4 caused by excessive pressure, and the reinforcing plate 524 arranged between the intermediate connecting plates 523 can ensure the overall shape of the rear mounting leg 52 and improve the structural stability of the rear mounting leg 52.

[0072] The stress opening 525 can provide a certain deformation allowance when the rear mounting leg 52 is deformed under pressure, preventing damage to the rear mounting leg 52 caused by excessive stress; and the arc-shaped connecting top plate 522 can decompose the stress into several angles to disperse the stress of the rear mounting leg 52 and ensure the integrity of the whole.

[0073] The application optimizes the photovoltaic module matrix structure, changes the connection mode of the overall structure and the base 3, improves the inclination angle of the photovoltaic module matrix, and uses the windproof plate, so that good connection stability is still achieved under the condition of reducing the base 3 and the overall material, the stable use of the photovoltaic panel is ensured, the material use of the photovoltaic matrix is reduced, and the manufacturing and installation cost of the photovoltaic module is greatly reduced.

[0074] In addition to the above-mentioned embodiments, the application can also have other implementation manners. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the application.
