[0044] In combination Figure 1 and Figure 2 As shown in the drawings, the present application provides a photovoltaic module mounting system, which includes an angle adjusting mechanism 100, a bottom beam 200, a cross beam 300 and a mounting foundation 110. First, referring to Figure 1 , in response to the slope of the ground 10, the bottom beam 200 is arranged along the first direction X of the ground 10 and connected end to end, and the length direction of the bottom beam 200 coincides with the first direction X. Referring toFigure 2 The bottom beams 200 are arranged in parallel and spaced apart from each other along a second direction Y which is perpendicular to the first direction X along the ground 10. The angle adjusting mechanism 100 is fixed to each bottom beam 200 through the mounting base 110, and the cross beam 300 is arranged on each angle adjusting mechanism 100 along the second direction Y, and the cross beam 300 is used for mounting the photovoltaic module 20. Each angle adjusting mechanism 100 is supported at different positions of the cross beam 300 along the length direction of the cross beam 300, so as to realize the multi-point support of the cross beam 300 by the angle adjusting mechanism 100, thereby ensuring the stability of the cross beam 300 as the fixing base of the photovoltaic module 20, and each angle adjusting mechanism 100 is used for jointly adjusting the angle of the cross beam 300, so that the photovoltaic module 20 changes the direction with the change of the angle of the cross beam 300.

[0045] It should be noted that in the conventional installation technology of the photovoltaic module 20, the photovoltaic module 20 is generally supported by punching holes in the ground 10 and anchoring the support column, which requires a large area of punching operation and the support is greatly affected by the geological conditions, especially in the soft soil mountain, the influence is more prominent. Therefore, the above-mentioned photovoltaic module installation system of the present application arranges the bottom beam 200 on the ground 10 according to the slope change of the ground 10, and uses the bottom beam 200 as the fixing base of the angle adjusting mechanism 100, so as to avoid the influence of the geological conditions on the installation of the photovoltaic module 20, and improve the adaptability to complex terrain. On the other hand, the bottom beam 200 as the fixing base can increase the contact area with the ground 10, improve the support stability of the installation of the photovoltaic module 20, and reduce the number of punching holes in the ground 10, which is friendly to the environment.

[0046] Exemplarily, the first direction X can be the north-south direction along the ground 10, and the length direction of each bottom beam 200 is arranged in the north-south direction, so it can be understood that the second direction Y is the east-west direction along the ground 10, and each bottom beam 200 is arranged in parallel.

[0047] Optionally, as shown in Figure 2 The photovoltaic module installation system of the present application can but not limited to include at least two photovoltaic module installation members 400, which are spaced apart along the extension direction of the cross beam 300 and fixed to the cross beam 300, so as to sequentially connect the multiple photovoltaic panels of the photovoltaic module 20 to the photovoltaic module installation member 400.

[0048] Optionally, as shown in Figure 3 and Figure 4As shown, the photovoltaic module mounting member 400 of the present application can be but is not limited to be implemented as a hoop structure for clamping on the cross beam 300; and the photovoltaic module mounting member 400 has a support plate 410 with a mounting hole 420 opened thereon for fixedly mounting a photovoltaic module bracket 440 for clamping the photovoltaic panel of the photovoltaic module 20, thus helping to improve the convenience and stability of the photovoltaic module 20 installation.

[0049] Preferably, as Figure 3 As shown, the photovoltaic module mounting member 400 is further provided with a rib plate 430, thus helping to strengthen the support of the photovoltaic module mounting member 400 to the photovoltaic module 20.

[0050] Preferably, the photovoltaic module mounting system of the present application can conform to the slope of the ground 10, and each bottom beam 200 is implemented to have different lengths, thus having higher applicability of the photovoltaic module mounting system of the present application on the mountain with larger slope.

[0051] Preferably, as Figure 5 As shown, the photovoltaic module mounting system can but is not limited to further include an anchoring structure 700, and the adjacent two bottom beams 200 are connected by the anchoring structure 700 along the first direction X of the ground 10. More preferably, the anchoring structure 700 includes an anchor rod 710 and a fixed plate 720, and the two ends of the fixed plate 720 are rotatably connected with the bottom beams 200 on both sides, and the anchor rod 710 is arranged through the fixed plate 720 and fixes the fixed plate 720 to the ground 10, thus being able to connect multiple bottom beams 200 into a stable whole structure, and through the rotation of the fixed plate 720 and the bottom beams 200, the fixed plate 720 is adjusted to a state of better fitting the ground 10, so that each bottom beam 200 can better adapt to the terrain changes and maintain good fitting effect with the ground 10, improving the adaptability to the mountain slope.

[0052] More preferably, as Figure 5 and Figure 6 As shown, the anchoring structure 700 can but is not limited to further include a pressing plate 730 abutting against the side of the fixed plate 720 away from the ground 10. The anchor rod 710 is arranged through the pressing plate 730 and the fixed plate 720, and the pressing plate 730 is pressed tightly to the fixed plate 720 by a nut.

[0053] Specifically, in this embodiment, the setting of the pressing plate 730 on the anchoring structure 700 enables the fixed plate 720 to be adjusted in angle in a movable and unfixed state, and enables the bottom beam 200 and the fixed plate 720 to be adjusted to a condition of good fitting with the ground 10, and then the fixed plate 720 is pressed tightly by the pressing plate 730, thus helping to improve the convenience and structural stability of the angle adjustment of the fixed plate 720.

[0054] Preferably, the anchoring structure 700 can be arranged at the corner position of the mountain slope with large fluctuation, and then the rotation of the fixing plate 720 and the bottom beam 200 can improve the adaptability to the mountain slope, and then improve the fixing effect of the bottom beam 200.

[0055] Preferably, as shown in Figure 6 , the anchoring structure 700 can but not limited to further include a side plate structure 740, and the fixing plate 720 is rotatably connected with the side plate structure 740 on both sides, and the side plate structure 740 is used for fixedly connecting with the end of the bottom beam 200, so as to improve the connection effect of the anchoring structure 700 to the bottom beam 200.

[0056] More preferably, the side plate structure 740 is in U shape, the side plate structure 740 has a U-shaped groove, and the bottom beam 200 is clamped in the U-shaped groove and fixed by bolts.

[0057] Optionally, in combination with Figure 1 and Figure 7 , the angle adjusting mechanism 100 includes a connecting member 120, a first plate 130, a second plate 140, a locking mechanism 150 and a fixing mechanism 160. The first plate 130 is connected with the installation base 110 through the connecting member 120, and the connecting member 120 can adjust the installation angle of the first plate 130 relative to the installation base 110 around the first axis, and the first axis is parallel or at an acute angle to the first plate 130. The second plate 140 is connected with the first plate 130, and the second plate 140 can rotate relative to the first plate 130 around the second axis to adjust the elevation angle a of the second plate 140 relative to the first plate 130, and the second axis is perpendicular to the first axis. The locking mechanism 150 is used for locking the relative position of the first plate 130 and the second plate 140. The fixing mechanism 160 is arranged on the side of the second plate 140 away from the first plate 130. The fixing mechanism 160 is used for installing the cross beam 300.

[0058] Preferably, as shown in Figure 7 , the first axis L1 is parallel to the first plate 130. In some other embodiments, the first axis L1 can also be at an acute angle to the first plate 130. Exemplarily, as shown in Figure 7 , the connecting member 120 can but not limited to include a first rotating plate 122 and a second rotating plate 123. The connection angle between the first plate 130 and the first rotating plate 122 is a right angle, and in some embodiments, the connection angle between the first plate 130 and the first rotating plate 122 can also be set as an obtuse angle, so that the first plate 130 is at an acute angle to the first axis L1.

[0059] The connecting member 120 can adjust the installation angle of the mounting base 110 relative to the first axis L1, so as to drive the fixing mechanism 160 to adjust the angle in the first adjustment plane relative to the first axis L1; meanwhile, the first plate 130 and the second plate 140 are rotationally connected, and the first axis L1 is perpendicular to the second axis L2, so as to drive the fixing mechanism 160 to adjust the angle in the second adjustment plane perpendicular to the first adjustment plane, thereby realizing the omnibearing adjustment of the roll angle (e.g. the left-right swing angle shown in Figure 8 FIG. 6) and the pitch angle α of the fixing mechanism 160, which helps to improve the angle adjustment effect.

[0060] For example, as shown in Figure 7 , the connecting member 120 can rotate relative to the mounting base 110 around the first axis L1 towards the vertical direction into the paper, so that the first axis L1 points to the horizontal left or right direction. The second axis L2 is arranged perpendicular to the first axis L1.

[0061] More specifically, when the first axis L1 points to the north-south direction, the connecting member 120 can rotate relative to the mounting base 110 in the plane pointing to the east-west direction; meanwhile, the second axis L2 is perpendicular to the first axis L1, so that when the first plate 130 can rotate relative to the second plate 140, the pitch angle α of the first plate 130 towards the north-south direction can be adjusted. Therefore, when the fixing mechanism 160 is used to fix the photovoltaic module 20, the demand for multi-angle adjustment of the photovoltaic module 20 can be met, and the adjustment range is large, which helps to improve the adjustment convenience.

[0062] For example, as shown in Figure 1 and Figure 7 , the photovoltaic module installation system can adjust the pitch angle α of the cross beam 300 in the north-south direction by adjusting the included angle between the first plate 130 and the second plate 140 in the first direction X towards the ground 10, thereby realizing the adjustment of the pitch angle α of the photovoltaic module 20 in the north-south direction.

[0063] Further, as shown in Figure 2 and Figure 8 , by adjusting the inclination angle of each connecting member 120 relative to the mounting base 110 in the second direction Y towards the ground 10, the angle of the cross beam 300 in the east-west direction can be adjusted, so as to realize the adjustment of the roll angle of the photovoltaic module 20 in the east-west direction. The photovoltaic module installation system realizes the omnibearing adjustment of the roll angle and the pitch angle α of the photovoltaic module 20, which is simple and efficient in operation and ensures the angle adjustment effect.

[0064] Optionally, the locking mechanism 150 can be, but is not limited to, a lock catch or a lock pin structure, which is used to fix the relative position of the first plate 130 and the second plate 140, and thus fix the elevation angle a.

[0065] Preferably, as shown in Figure 7 The locking mechanism 150 includes a first adjusting plate 151, a second adjusting plate 152, and a first locking bolt 153. The first adjusting plate 151 is rotationally connected to the first plate 130, and the second adjusting plate 152 is rotationally connected to the second plate 140. At least part of the structure of the first adjusting plate 151 can be attached to the second adjusting plate 152. The positions where the first adjusting plate 151 and the second adjusting plate 152 are attached to each other are provided with through holes. The first locking bolt 153 is used to pass through the through holes and clamp the first adjusting plate 151 and the second adjusting plate 152, so as to fix the relative position of the first adjusting plate 151 and the second adjusting plate 152, so that the first adjusting plate 151 and the second adjusting plate 152 limit the rotation of the second plate 140 relative to the first plate 130, achieve the fixation of the elevation angle a, and are simple and reliable to operate. The first plate 130, the second plate 140, the first adjusting plate 151, and the second adjusting plate 152 are enclosed to form a triangular structure, which helps to improve the structural strength.

[0066] Preferably, the through holes are implemented as long holes, so as to facilitate the adaptive adjustment of the first locking bolt 153 according to the size of the elevation angle a and the relative position of the first adjusting plate 151 and the second adjusting plate 152.

[0067] Preferably, as shown in Figure 7 The first adjusting plate 151 is provided with a first sawtooth 1511, and the second adjusting plate 152 is provided with a second sawtooth 1521. When the first adjusting plate 151 is attached to the second adjusting plate 152, the first sawtooth 1511 and the second sawtooth 1521 are engaged with each other, so as to improve the tightness of the mutual attachment of the first adjusting plate 151 and the second adjusting plate 152, prevent the mutual sliding of the first adjusting plate 151 and the second adjusting plate 152, and improve the structural stability.

[0068] Optionally, as shown in Figure 7 and Figure 8 The connecting member 120 can include, but is not limited to, a second locking bolt 121, a first rotating plate 122, and a second rotating plate 123. The first rotating plate 122 and the second rotating plate 123 are both perpendicularly connected to the side of the first plate 130 away from the second plate 140, and the first rotating plate 122 and the second rotating plate 123 are parallel and spaced apart from each other.

[0069] The first rotating plate 122 is provided with a first waist hole combination 1221, and the second rotating plate 123 is provided with a second waist hole combination 1231. The second locking bolt 121 passes through the first waist hole combination 1221, the mounting base 110, and the second waist hole combination 1231. The first waist hole combination 1221 and the second waist hole combination 1231 are both circular arcs with the center of the circle on the first axis L1, so that the first rotating plate 122 and the second rotating plate 123 rotate around the first axis L1 when the second locking bolt 121 moves along the first waist hole combination 1221 and the second waist hole combination 1231.

[0070] Preferably, as shown in Figure 8 The first waist hole combination 1221 can be, but is not limited to, at least two waist holes symmetrically distributed around the center of the circle. Understandably, the number of waist holes can be determined according to actual needs. Similarly, the second waist hole combination 1231 is implemented to have a number of waist holes corresponding to the number of waist holes of the first waist hole combination 1221. Further, the second locking bolt 121 is implemented to have a number of waist holes corresponding to the number of waist holes of the first waist hole combination 1221 and the second waist hole combination 1231.

[0071] Therefore, in this embodiment, the first axis L1 is an axis passing through the center of the first rotating plate 122 and the second rotating plate 123, so that the first rotating plate 122 and the second rotating plate 123 can rotate around the first axis L1 along the opening trajectories of the first waist hole combination 1221 and the second waist hole combination 1231 under the restriction of the second locking bolt 121.

[0072] Specifically, the rotation angle of the connecting member 120 is limited by the opening length of the waist holes of the first waist hole combination 1221 and the second waist hole combination 1231. Therefore, in the embodiment in which the first rotating plate 122 is provided with the first waist hole combination 1221 and the second rotating plate 123 is provided with the second waist hole combination 1231, the opening length of the waist holes can be designed according to actual needs to meet the required range of angle adjustment of the connecting member 120.

[0073] Continuing to combine Figure 7 Optionally, in some embodiments, a reinforcing plate 170 is further provided between the first plate 130 and the second rotating plate 123, so that the support strength of the angle adjustment mechanism 100 on the photovoltaic module 20 can be improved.

[0074] Optionally, referring back to Figure 1, the mounting base 110 can but not limited to be implemented as including a first column 111 and a second column 112. The connecting member 120 is connected to one end of the first column 111, and one end of the second column 112 is connected to the first column 111 near the end of the connecting member 120. The other end of the first column 111 and the second column 112 is fixed at different positions of the bottom beam 200, so that the angle between the first column 111 and the second column 112 can be adjusted in time, and the first column 111 and the second column 112 are fixed at different positions of the bottom beam 200 to meet the support requirements of the fixing mechanism 160 to the photovoltaic module 20.

[0075] Specifically, the bottom beam 200 can be placed on the ground 10 and serve as the mounting base 110 of the first column 111 and the second column 112, so that only the orientation of the bottom beam 200 needs to be fixed to achieve the adjustment of the orientation of the photovoltaic module 20 on the fixing mechanism 160.

[0076] More specifically, in the scenario of a tilted mountain, by fixing the first column 111 and the second column 112 to the bottom beam 200, the installation stability of the angle adjusting mechanism 100 can be improved, and the influence of the terrain and soil quality on the installation stability of the angle adjusting mechanism 100 can be avoided. Therefore, the above-mentioned photovoltaic module installation system can adapt to the scenario of a large mountain slope, thereby improving the installation effect of the photovoltaic module 20.

[0077] Optionally, referring to Figure 1 , Figure 9 and Figure 10 , the photovoltaic module installation system can but not limited to further include a first mounting member 500 and a second mounting member 600. The first column 111 and the second column 112 are respectively fixed at different positions of the bottom beam 200 through the first mounting member 500 and the second mounting member 600, and the first column 111 is rotatably connected to the first mounting member 500, and the second column 112 is rotatably connected to the second mounting member 600. The first column 111 and the second column 112 can respectively rotate relative to the first mounting member 500 and the second mounting member 600 to change the angle between the first column 111 and the second column 112 and the bottom beam 200, so that the support angle between the first column 111 and the second column 112 can be adjusted, so that the scenario of a large slope such as a mountain can be adapted, and the support angle between the first column 111 and the second column 112 is adjusted to maintain the support of the first column 111 and the second column 112.

[0078] Optionally, as Figure 9 and Figure 10As shown, the first mounting member 500 and the second mounting member 600 can but not limited to each include a fixing portion 510, a rotating portion 520 and a third locking bolt 530. The fixing portion 510 can be clamped at different positions of the bottom beam 200. The rotating portion 520 includes a third rotating plate 521 and a fourth rotating plate 522 which are parallel to each other. The third rotating plate 521 is provided with a third waist hole 5211, and the fourth rotating plate 522 is provided with a fourth waist hole 5221.

[0079] The third locking bolt 530 of the first mounting member 500 is threaded through the third waist hole 5211, the fourth waist hole 5221 and the first stand 111. When the third locking bolt 530 of the first mounting member 500 moves along the third waist hole 5211 and the fourth waist hole 5221, the first stand 111 rotates relative to the third rotating plate 521 and the fourth rotating plate 522.

[0080] The third locking bolt 530 of the second mounting member 600 is threaded through the third waist hole 5211, the fourth waist hole 5221 and the second stand 112. When the third locking bolt 530 of the second mounting member 600 moves along the third waist hole 5211 and the fourth waist hole 5221, the second stand 112 rotates relative to the third rotating plate 521 and the fourth rotating plate 522, thereby adjusting the support angle between the first stand 111 and the second stand 112.

[0081] Optionally, as shown in Figure 10 and Figure 11 The bottom beam 200 can but not limited to be implemented as a cylinder or a cuboid. Correspondingly, the fixing portion 510 is implemented as a hoop structure and is adapted to the shape of the side of the bottom beam 200 to clamp the bottom beam 200.

[0082] Optionally, as shown in Figure 2 In the second direction Y of the ground 10, adjacent mounting bases 110 are pulled by the ropes 30, thereby improving the overall strength of the structure of the photovoltaic module installation system and further improving the installation stability of the photovoltaic module 20.

[0083] Preferably, the ropes 30 pull adjacent first stands 111 to improve the installation stability of the photovoltaic module 20.

[0084] More preferably, in combination with Figure 2 The first stand 111 is provided with a first pull hook structure 1111 and a second pull hook structure 1112. The first pull hook structure 1111 is located on the higher side close to the cross beam 300, and the second pull hook structure 1112 is located on the lower side close to the bottom beam 200. The first pull hook structure 1111 of one first stand 111 and the second pull hook structure 1112 of an adjacent first stand 111 are crossed and pulled by the ropes 30, thereby improving the stability of the mutual pulling of the first stands 111.
