[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] The following is combined Figures 1 to 8 The following describes embodiments of the present invention.

[0035] According to an embodiment of the present invention, in a first aspect, a cantilevered photovoltaic support is provided, including a tripod 10 and a connecting rod 20. Two tripods 10 are provided, with adjacent tripods 10 spaced apart. Each tripod 10 includes a vertical rod 11, a diagonal beam 12, and a diagonal brace 13. The vertical rod 11 and the diagonal beam 12 are connected and form an angle α, which satisfies α < 90°. The two ends of the diagonal brace 13 are respectively connected to the vertical rod 11 and the diagonal beam 12 to form a triangle. The vertical rod 11 is adapted to abut against a wall. Two connecting rods 20 are provided, with the two ends of the connecting rod 20 respectively connected to the two spaced-apart tripods 10.

[0036] The cantilevered photovoltaic support structure of this embodiment, with the vertical rod 11, inclined beam 12 and inclined brace 13 forming a triangular structure, makes full use of the mechanical properties of each component, uses very little material, saves material, and gives the cantilevered photovoltaic support excellent stability; and the angle between the vertical rod 11 and the inclined beam 12 is less than 90°, thus forming a drainage slope to prevent water from accumulating on the photovoltaic module 70 and affecting the service life of the cantilevered photovoltaic support structure and the conversion efficiency of the photovoltaic module 70.

[0037] It should be noted that the cantilevered photovoltaic support structure in the relevant technology is prone to accumulating water or debris on the photovoltaic module 70, which affects the conversion efficiency of the photovoltaic module 70. Furthermore, the accumulation of water and debris increases the load on the photovoltaic support structure, which is easily damaged under a large load, affecting its service life.

[0038] Therefore, in this embodiment, the angle between the vertical rod 11 and the inclined beam 12 is less than 90°, thereby forming a drainage slope. Under the guidance of the drainage slope, debris and water can easily slide down the photovoltaic support, thereby reducing the accumulation of debris on the photovoltaic module 70, and thus improving the service life of the cantilevered photovoltaic support and the conversion efficiency of the photovoltaic module 70.

[0039] Specifically, such as Figure 2 As shown, there are two connecting rods 20. One connecting rod 20 has its two ends connected to the same end of the two inclined beams 12, and the other connecting rod 20 has its two ends connected to the other end of the two inclined beams 12.

[0040] It should be noted that in other alternative implementations, the number of tripods 10 can be selected as three, four, etc., depending on the actual situation, thereby enhancing the structural strength and load-bearing capacity of the cantilevered photovoltaic support.

[0041] Specifically, such as Figure 5 and Figure 7 As shown, the vertical rod 11 is connected to the inclined beam 12 and forms an included angle α.

[0042] It should be noted that the included angle α can be adjusted according to the actual situation.

[0043] It is worth noting that the cantilevered photovoltaic support structure formed by the tripod 10 and connecting rod 20 has fewer structural components, is easy to install, and can be quickly completed.

[0044] In one embodiment, such as Figure 2 As shown, the cantilevered photovoltaic bracket also includes a fixing angle bracket 30 and a first fastener 40. The fixing angle bracket 30 is connected to the vertical rod 11, and a first mounting hole 31 is provided on the fixing angle bracket 30. The first fastener 40 passes through the first mounting hole 31 and is adapted to be fastened to the wall. The cantilevered photovoltaic bracket is detachably fastened to the wall by the first fastener 40, which facilitates the adjustment of the position of the cantilevered photovoltaic bracket.

[0045] Specifically, such as Figure 2 , Figure 4 and Figure 5 As shown, each tripod 10 has three fixed corner brackets 30 spaced apart.

[0046] Of course, in other alternative implementations, the number of fixed corner brackets 30 can be adjusted according to the actual situation, such as four or five.

[0047] Specifically, the first fastener 40 is an anchor bolt, which passes through the first mounting hole 31 and is fastened to the wall.

[0048] It should be noted that, in other alternative embodiments, fasteners can also be used to directly penetrate the vertical rod 11 and fasten it to the wall to fix the cantilevered photovoltaic bracket to the wall.

[0049] Furthermore, such as Figure 5 As shown, the first mounting hole 31 is an elongated oval hole. The first mounting hole 31 is set as an elongated oval hole to accommodate the deviation of the anchor bolt installation and improve the installation adaptability of the cantilevered photovoltaic bracket.

[0050] In one embodiment, such as Figure 6 As shown, the connecting rod 20 includes a rod body 21 and a connector 22. The connector 22 is located near the end of the rod body 21 and is connected to the inclined beam 12. By providing the connector 22, the assembly of the connecting rod 20 and the inclined beam 12 is simplified, and the assembly efficiency is improved.

[0051] Specifically, such as Figure 6 As shown, each rod 21 is provided with two connectors 22.

[0052] Furthermore, the connector 22 is a U-shaped part with a round hole at the bottom of the groove. Fasteners are used to pass through the round hole to connect the U-shaped part to the inclined beam 12.

[0053] In one embodiment, such as Figure 2 and Figure 3 As shown, the cantilevered photovoltaic support also includes cable clamps 50. Three cable clamps 50 are provided, each connected to the connecting rod 20, forming a cable routing space suitable for placing cables. The cable clamps 50 create this routing space, facilitating the organization and collection of cables from the photovoltaic module 70, thus improving the neatness of the cantilevered photovoltaic support.

[0054] Specifically, the cable clamp 50 is detachably connected to the connecting rod 20 via fasteners. The cable clamp 50 has an L-shaped structure to facilitate cable collection.

[0055] Of course, in other alternative implementations, the number of cable clamps 50 can be adjusted according to the actual situation.

[0056] In one embodiment, such as Figure 5As shown, the vertical rod 11 and the inclined beam 12 are pipe fittings. The cantilevered photovoltaic support also includes a sealing component 60, which covers the pipe openings. By sealing the pipe openings with the sealing component 60, insects and birds can be prevented from entering, and waterproofing is also provided, while improving the overall aesthetics of the cantilevered photovoltaic support.

[0057] Specifically, the vertical rod 11 and the inclined beam 12 are square tubular components, which form a closed structure through cooperation with the sealing component 60.

[0058] According to an embodiment of the present invention, in a second aspect, a photovoltaic system is also provided, including the aforementioned cantilevered photovoltaic support and photovoltaic module 70, wherein the photovoltaic module 70 is disposed on the inclined beam 12.

[0059] In one embodiment, such as Figure 7 As shown, the photovoltaic module 70 includes a module frame 71 and a photovoltaic panel 72. A mounting groove is formed on the module frame 71, and the photovoltaic panel 72 is disposed in the mounting groove. The module frame 71 is disposed on the inclined beam 12.

[0060] Furthermore, such as Figure 3 and Figure 4 As shown, the cantilevered photovoltaic bracket also includes a flat plate 80, which is connected to the connecting rod 20. The flat plate 80 has a second mounting hole 81. The photovoltaic system also includes a clamping member 90 and a second fastener 100. A through hole is formed on the module frame 71. One end of the clamping member 90 passes through the through hole and abuts against the module frame 71, while the other end abuts against the flat plate 80. A third mounting hole 94 is formed on the clamping member 90. The second fastener 100 passes through the third mounting hole 94 and the second mounting hole 81 in sequence and is fastened to the flat plate 80. A portion of the second fastener 100 passes through the through hole in the module frame 71 and presses the module frame 71 against the connecting rod 20, thus forming a concealed assembly and improving the neatness and aesthetics of the photovoltaic system.

[0061] Specifically, the second fastener 100 is a bolt.

[0062] It should be noted that the second mounting hole 81 can be set as an oblong hole to improve adaptability.

[0063] Furthermore, such as Figure 8 As shown, the clamping member 90 includes a clamping part 91, a connecting part 92 and a supporting part 93. The two ends of the connecting part 92 are connected to the clamping part 91 and the supporting part 93 respectively. The clamping part 91 passes through the through hole and abuts against the component frame 71. The supporting part 93 abuts against the flat plate 80. A third mounting hole 94 is provided on the connecting part 92.

[0064] Specifically, the clamping part 91, the connecting part 92, and the supporting part 93 are integrally bent from the plate to enhance the structural strength of the clamping part 90.

[0065] Specifically, when the second fastener 100 is tightened, the clamping part 91 presses the component frame 71 onto the connecting rod 20, and a buffer space is formed between the connecting part 92, the support part 93, the connecting rod 20 and the flat plate 80, so that the assembly of the clamping part 90 has a certain tolerance for deviation.

[0066] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
