[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] The embodiment of the utility model discloses a photovoltaic support device, comprising at least two groups of photovoltaic brackets 1, each group of photovoltaic brackets 1 is triangular, and each group of photovoltaic brackets 1 is fixed to a wall 4 above a window 3 through a fixed connecting plate 2. All photovoltaic brackets 1 are arranged side by side, so that all photovoltaic brackets 1 support photovoltaic modules 5 obliquely above the window 3, so that the photovoltaic modules 5 can collect solar energy for power generation and shade the window 3, so that the photovoltaic modules 5 can replace traditional awnings and improve the space utilization rate of the photovoltaic modules 5 on the building.

[0037] Specifically, the photovoltaic support device includes two groups of photovoltaic brackets 1, that is, one group of photovoltaic modules 5 is supported by two groups of photovoltaic brackets 1. Of course, the number of photovoltaic brackets 1 included in the photovoltaic support device can be flexibly adjusted according to the specifications of the photovoltaic modules 5 or the width of the window 3, and is not specifically limited here.

[0038] In the first specific embodiment, the wall surface 4 above the window 3 is a straight wall surface, and the fixed connecting plate 2 is a straight connecting plate, and the straight connecting plate is parallel to the straight wall surface 4 .

[0039] Each set of photovoltaic brackets 1 includes a fixing rod 11 arranged parallel to the wall surface 4, and the fixing rod 11 is fixedly connected to the bottom end of the fixed connecting plate 2. The bottom end of the fixed connecting plate 2 is the connecting end, and the fixing rod 11 is parallel to the connecting end of the fixed connecting plate 2. At least one connecting bolt 7 is passed through the fixing rod 11 and the fixed connecting plate 2, and a locking nut 71 is arranged at the tail end of each connecting bolt 7. By tightening the locking nut 71, the fixing rod 11 is reliably fixed to the fixed connecting plate 2. Specifically, two connecting bolts 7 are passed through the fixing rod 11 and the fixed connecting plate 2. Of course, the number of connecting bolts 7 and the connection method between the fixing rod 11 and the fixed connecting plate 2 are not limited thereto. For example, the fixing rod 11 and the fixed connecting plate 2 can also be fixedly connected by welding or riveting.

[0040] The fixed connecting plate 2 is penetrated by a fixing bolt 6, which passes through the fixed connecting plate 2 and is inserted into the wall 4. The fixing bolt 6 fixes the fixing rod 11 to the wall 4 through the fixed connecting plate 2, ensuring that the photovoltaic bracket 1 is reliably fixed to the wall 4. The fixing bolt 6 is specifically a chemical anchor bolt, so that it has sufficient strength to stably support the photovoltaic bracket 1. Of course, the fixing bolt 6 can also be an expansion anchor bolt, or a connecting assembly composed of a threaded nail or an expansion sleeve, which is not specifically limited here. In the first specific embodiment, the fixed connecting plate 2 is only vertically provided with one fixing bolt 6.

[0041] Each set of photovoltaic brackets 1 also includes a support rod 12 set at an angle to the fixing rod 11, and the support rod 12 is used to parallely support the photovoltaic assembly 5; positioning bolts 8 are respectively vertically fixed at both ends of the support rod 12, and the positioning bolts 8 are used to be fixedly connected to the L-shaped buckles 9 fixed at both ends of the photovoltaic assembly 5.

[0042] Each set of photovoltaic brackets 1 also includes a support rod 12 that is set at an angle to the fixed rod 11. The support rod 12 is hingedly connected to the fixed rod 11 through a rotating pin, so that the support rod 12 can rotate relative to the fixed rod 11 around the rotating pin, providing conditions for adjusting the inclination angle of the support rod 12. The support rod 12 is used to support the photovoltaic module 5 in parallel, that is, the photovoltaic module 5 is placed parallel to the support rod 12. Positioning bolts 8 are respectively fixed vertically at both ends of the support rod 12, and L-shaped buckles 9 are respectively clamped at both ends of the photovoltaic module 5. The positioning bolts 8 are fixedly connected with the L-shaped buckle 9, so that the photovoltaic module 5 is reliably fixed on the support rod 12 through the L-shaped buckle 9, so that the photovoltaic module 5 rotates synchronously with the support rod 12. Of course, the connection method between the photovoltaic module 5 and the support rod 12 is not limited to this.

[0043] The L-shaped buckle 9 includes a buckle body 91, a clamping portion 92 integrally fixed to the top of the buckle body 91, and a connecting end integrally fixed to the bottom of the buckle body 91. The buckle body 91 is a rectangular frame, so that the L-shaped buckle 9 has sufficient strength to support the photovoltaic module 5. Reinforcing ribs can be added in the rectangular frame to enhance the rigidity of the buckle body 91 and improve the bearing capacity of the rectangular frame, so that the L-shaped buckle 9 can withstand heavier photovoltaic modules 5. The clamping portion 92 is L-shaped, and a U-shaped slot is formed between the clamping portion 92 and the buckle body 91. The U-shaped slot is used to clamp with the side edge of the photovoltaic module 5, limit the upward and downward movement of the photovoltaic module 5 relative to the support rod 12, so that the photovoltaic module 5 is reliably fixed on the support rod 12, and conveniently disassemble and assemble the photovoltaic module 5 and the L-shaped buckle 9. The clamping portion 92 is elastic and has a tendency to bend toward the buckle body 91, so that the U-shaped slot clamps the photovoltaic module 5 by elastic force, further ensuring that the L-shaped buckle 9 can reliably fix the photovoltaic module 5. The connecting portion 93 is in the shape of a flat plate and is parallel to the support rod 12 . The connecting portion 93 is fixedly connected to the positioning bolt 8 .

[0044] A supporting boss 121 is integrally formed on one side of the support rod 12, and the positioning bolts 8 are vertically passed through the two ends of the supporting boss 121. The supporting boss 121 is set toward the photovoltaic component 5 and is parallel to the connecting part 93 of the L-shaped clip 9, so that the photovoltaic component 5 is fixed on the supporting boss 121 with the help of the L-shaped clip 9, so that a height difference is formed between the L-shaped clip 9 and the two ends of the support rod 12, so as to prevent the L-shaped clip 9 from hindering the rotation of the support rod 12 relative to the fixing rod 11.

[0045] Each set of photovoltaic brackets 1 also includes an adjusting rod 13 connected between the fixed rod 11 and the support rod 12. An adjusting component 14 is provided between the fixed rod 11 and the adjusting rod 13 and between the support rod 12 and the adjusting rod 13. The adjusting component 14 is used to adjust the inclination angle of the support rod 12, so that the photovoltaic bracket 1 can flexibly adjust the inclination angle of the photovoltaic component 5 according to the lighting duration and lighting angle, thereby ensuring that the photovoltaic component 5 is fully illuminated.

[0046] Each set of adjustment components 14 includes a plurality of adjustment holes 141 provided on the fixed rod 11 and the support rod 12 and an adjustment pin 142 that selectively passes through the adjustment hole 141 and is connected to the adjustment rod 13. In other words, the fixed rod 11 is provided with a plurality of adjustment holes 141, and the support rod 12 is also provided with a plurality of adjustment holes 141, and the fixed rod 11 and the adjustment rod 13 and the support rod 12 and the adjustment rod 13 are arranged at an angle through the adjustment pin 142. Under normal conditions, the adjustment rod 13 is perpendicular to the fixed rod 11. When the adjustment pin 142 between the fixed rod 11 and the adjustment rod 13 is arranged higher than the adjustment pin 142 between the support rod 12 and the adjustment rod 13, the angle between the support rod 12 and the fixed rod 11 becomes smaller, so that the inclination angle of the support rod 12 becomes smaller. When the adjustment pin 142 between the fixed rod 11 and the adjustment rod 13 is set lower than the adjustment pin 142 between the support rod 12 and the adjustment rod 13, the angle between the support rod 12 and the fixed rod 11 becomes larger, so that the inclination angle of the support rod 12 becomes smaller.

[0047] Compared with the first specific embodiment, the second specific embodiment is to change the shape of the fixed connecting plate 2, and the rest of the technical solutions are the same as the first specific embodiment. In the second specific embodiment, the wall surface 4 above the window sill is a raised wall surface, and the fixed connecting plate 2 is specifically an L-shaped connecting plate, and the L-shaped connecting plate is hooked on the raised wall surface 4. In other words, the shape of the fixed connecting plate 2 can be adjusted according to the shape of the wall surface 4, so that the fixed connecting plate 2 can be adapted to different types of wall surfaces 4, and the application range is wider.

[0048] In the second specific embodiment, the fixed connection plate 2 is formed by a horizontal fixing portion and a vertical connection portion intersecting vertically, and the vertical connection portion is fixedly connected to the fixing rod 11 by a connecting bolt 7. However, it is required that, in the second specific embodiment, the fixed connection plate 2 is penetrated with two fixing bolts 6, wherein a fixing screw rod is vertically penetrated each of the horizontal fixing portion and the vertical connection portion, and the two fixing bolts 6 intersect vertically, but the two fixing bolts 6 will not interfere with each other in the wall surface 4.

[0049] Of course, the shape of the fixed connecting plate 2 is not limited to the above two embodiments, and the number of the fixing bolts 6 of the fixed connecting plate 2 can be flexibly adjusted according to the shape of the fixed connecting plate 2, which is not specifically limited here.

[0050] The embodiment of the utility model also discloses a distributed photovoltaic power generation system, including a photovoltaic module 5 and the above-mentioned photovoltaic support device, wherein the photovoltaic module 5 is tiltedly arranged on the photovoltaic support device, and the technical solutions of the two subjects are the same and have the same beneficial effects.

[0051] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0052] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
