Description

Technical Field

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. It mainly consists of three major parts: photovoltaic panels, controllers, and inverters, and the main components are composed of electronic components. Solar cells can be encapsulated and protected after being connected in series to form large-area solar cell modules, and then combined with components such as power controllers to form a photovoltaic power generation device. Photovoltaic power generation is not restricted by the geographical distribution of resources and can be applied in various complex terrains such as wastelands, gobi deserts, and hills. With the development and promotion of environmental protection energy at home and abroad, photovoltaic power generation has been more and more widely used.

[0003] In the prior art, due to the terrain complexity of mountainous areas, the laying of photovoltaic matrices is restricted to a certain extent. Currently, the installation method of photovoltaic matrices in mountainous areas is to control the depth of ground piles driven into the ground. The depths driven into the ground at different positions are different, aiming to make the tops of the ground piles approximately on the same inclined plane to ensure that a flat photovoltaic matrix can be laid after the installation of the photovoltaic brackets. The disadvantages caused by this installation method are as follows:

[0004] ① The depth of the ground piles driven into the ground directly determines the stability of the brackets. Different depths will cause the strength of the overall brackets to be uneven, and the ability to resist harsh weather such as strong winds and snow will be weakened;

[0005] ② Only the height of local positions can be adjusted by adjusting the ground piles. The operation is difficult and the labor cost is high, resulting in low adjustability of the overall brackets and poor adaptability to mountainous areas. Summary of the Invention

[0049] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail below through specific embodiments.

[0050] The present invention is a mountain photovoltaic support structure, including an inclined rod 1, a cross rod 2, a ground pile 3, an angle adjustment component 4 and a height adjustment component 5;

[0051] The ground pile 3 is driven into the ground according to the depth required by the construction strength;

[0052] The bottom surface of the cross rod 2 is installed at the top end of the ground pile 3 through the height adjustment component 5, and the distance from the top end of the ground pile 3 is adjusted through the height adjustment component 5;

[0053] The inclined rod 1 is installed on the top surface of the cross rod 2 through the angle adjustment component 4 and is perpendicular to the cross rod 2; the cross rod 2 is used to support the photovoltaic panel, and the slope of the cross rod 2 is adjusted through the angle adjustment component 4.

[0054] Reference Figures 1 to 13 As shown, a specific embodiment of the present invention is shown.

[0055] The above-mentioned angle adjustment component 4 includes an adapter 41 and a number of first fixing parts 42 and second fixing parts 43; the adapter 41 is provided with a channel 411, the axial direction of the channel 411 is parallel to the cross rod 2, and the channel 411 has a circular arc top 412, and at least one strip hole 413 is opened on the circular arc top 412; a first connecting plate 414 extends from the bottom surface of the adapter 41 to the side, and at least one first screw hole 415 is opened on the first connecting plate 414; the first bolt 44 is sequentially passed through the first fixing part 42 and the strip hole 413 and locked into the first nut 45 located in the channel 411, so that the first fixing part 42 and the adapter 41 are clamped on the frame of the photovoltaic panel to realize the installation of the photovoltaic panel on the inclined rod 1; the second bolt 46 is passed through the second fixing part 43 and locked into the first screw hole 415, so that the second fixing part 43 and the first connecting plate 414 are clamped on the cross rod 2 to realize the installation between the cross rod 2 and the inclined rod 1.

[0056] In some embodiments of the angle adjustment component 4, the first fixing member 42 and the second fixing member 43 are both pressing blocks provided with perforations; a first sliding rail 11 for the first fixing member 42 to be movably fitted is provided on the bottom side of the inclined rod 1; a second sliding rail 21 for the second fixing member 43 to be movably fitted is provided on the top side of the cross bar 2. The first fixing member 42 is slidably fitted with the first sliding rail 11, and the second fixing member 43 is slidably fitted with the second sliding rail 21, so that the position of the adapter 41 on the inclined rod 1 / cross bar 2 can be arbitrarily adjusted within the length range of the inclined rod 1 / cross bar 2, and the installation is more flexible; at the same time, the cooperation form of the pressing block and the sliding rail can minimize the volume of the first fixing member 42, making the installation more convenient and the cost lower.

[0057] Further, there are two strip-shaped holes 413 opened on the arc top 412. Correspondingly, the first sliding rails 11 are provided on both sides of the bottom surface of the inclined rod 1, that is, both sides of the bottom of the inclined rod 1 are installed on the adapter 41 through the first fixing members 42, and the structure is more firm.

[0058] At the same time, there are two first screw holes 415 opened on the first connecting plate 414. That is, the second fixing member 43 for assembling the cross bar 2 is locked on the first connecting plate 414 by two first bolts 44, which can prevent the first fixing member 42 from loosening due to the force of rotation, and the structure is more firm.

[0059] Furthermore, the first connecting plates 414 are formed on both sides of the bottom surface of the adapter 41. Correspondingly, the second sliding rails 21 are provided on both sides of the top surface of the cross bar 2, that is, both sides of the top of the cross bar 2 are fixed to the adapter 41 through the second fixing members 43, and the structure is more firm.

[0060] In some embodiments of the angle adjustment component 4, the plane where the center line of the strip-shaped hole 413 is located is perpendicular to the axial direction of the channel 411, so that when the inclined rod 1 adjusts the slope, it always remains perpendicular to the cross bar 2.

[0061] In some embodiments of the angle adjustment component 4, the first nut 45 is provided with an arc surface 451 that matches the inner side wall of the arc top 412, so that when the first nut 45 adjusts its position in the channel 411, it always maintains the largest contact area with the arc top 412, thereby improving the stability after the first bolt 44 is locked, and avoiding the stress of the first nut 45 on the arc top 412 being too concentrated at a certain position when the first bolt 44 is locked, and the service life of the adapter 41 is extended.

[0062] The above-mentioned height adjustment assembly 5 includes at least two pairs of sliders 51, support rods 52, and a connecting seat 53; the sliders 51 are slidably fitted to the bottom surface of the cross bar 2; the connecting seat 53 is installed at the top end of the ground pile 3, and a plurality of pivot holes 531 are provided on its side wall. The pivot holes 531 are vertically arranged waist-shaped holes; the upper and lower ends of the support rod 52 are respectively pivotally fitted to the slider 51 and the pivot hole 531, and the height of the support rod 52 in the pivot hole 531 is adjustable. Since both the upper and lower ends of the support rod 52 are rotatable, and the position of the slider 51 on the cross bar 2 is adjustable, the slope of the support rod 52 can be adjusted. The greater the slope of the support rod 52, the greater the distance between the supported cross bar 2 and the ground pile 3, which realizes the upward adjustment of the height of the cross bar 2, and vice versa for the downward adjustment of the height of the cross bar 2.

[0063] In some embodiments of the height adjustment assembly 5, the above-mentioned height adjustment assembly 5 further includes a plurality of limiting blocks 54; a plurality of anti-slip lines 532 are provided on the opposite surfaces of the limiting blocks 54 and the side wall of the connecting seat 53. After passing a third bolt 55 through the limiting block 54, the pivot hole 531, and the lower end of the support rod 52, it is threadedly connected to a second nut 56 fitted on the other side of the connecting seat 53 to realize the installation and fixation of the lower end of the support rod 52 on the connecting seat 53, and the position of the support rod 52 in the pivot hole 531 is fixed through the anti-slip lines 532 between the limiting block 54 and the connecting seat 53, improving the structural firmness.

[0064] Furthermore, anti-slip lines 532 are provided on both sides of the connecting seat 53, and limiting blocks 54 are provided on both sides of the connecting seat 53, further improving the position stability of the support rod 52 on the connecting seat 53 and realizing a higher and stronger load-bearing capacity.

[0065] In some embodiments of the height adjustment assembly 5, the above-mentioned height adjustment assembly 5 further includes a plurality of third fixing members 57; a second connecting plate 511 extends from the top surface of the slider 51 to the side, and at least one second screw hole 512 is provided on the second connecting plate 511; a fourth bolt 58 is passed through the third fixing member 57 and locked into the second screw hole 512, so that the third fixing member 57 and the second connecting plate 511 are clamped on the cross bar 2 to realize the installation between the cross bar 2 and the support rod 52.

[0066] Further, the third fixing member 57 is a pressing block provided with a perforation; a third sliding rail 22 for the third fixing member 57 to movably cooperate with is arranged on the side of the bottom surface of the cross bar 2. The third fixing member 57 is in sliding connection with the third sliding rail 22, so that the position of the slider 51 on the cross bar 2 can be adjusted arbitrarily within the length range of the cross bar 2, and the installation is more flexible; at the same time, by adopting the cooperation form of the pressing block and the sliding rail, the volume of the third fixing member 57 can be minimized, the installation is more convenient and the cost is lower. Preferably, second connecting plates 511 are formed on both sides of the top surface of the slider 51, and the third sliding rails 22 are arranged on both sides of the bottom surface of the corresponding cross bar 2, that is, both sides of the bottom surface of the cross bar 2 are fixed to the slider 51 through the third fixing member 57 (i.e., the pressing block), and the structure is more firm.

[0067] In some embodiments of the height adjustment assembly 5, a first pivot groove 513 for the upper end of the support rod 52 to pivotally cooperate with is arranged on the bottom surface of the slider 51, a second pivot groove 533 for the lower end of the support rod 52 to pivotally cooperate with is arranged on the top surface of the connecting seat 53, and a pivot hole 531 penetrates through the side wall of the second pivot groove 533.

[0068] In some embodiments of the height adjustment assembly 5, a third connecting plate 534 extends from the bottom surface of the connecting seat 53 to the side, and an installation hole 535 for assembling the ground pile 3 is arranged on the third connecting plate 534.

[0069] Further, a flange plate 31 is arranged at the top end of the ground pile 3, and the installation hole 535 is an oblong hole, so that the position and angle of the connecting seat 53 at the top end of the ground pile 3 can be adjusted within a certain range to adapt to variable on-site installation conditions.

[0070] At the same time, the third connecting plates 534 are formed on both sides of the bottom surface of the connecting seat 53, so that both sides of the connecting seat 53 are locked to the top end of the ground pile 3, and the structure is more firm.

[0071] Through the above scheme, the present invention realizes the installation between the cross bar 2 and the ground pile 3 through the height adjustment assembly 5, and realizes the installation between the cross bar 2 and the inclined rod 1 through the angle adjustment assembly 4. The height adjustment assemblies 5 are independent of each other. The present invention is more suitable for mountainous areas with undulating terrain.
