The second fastener passes through the crossbeam and is fastened to the screw-in portion. The third fastener passes through the inclined beam and the main body in sequence and is fastened to the main body.

[0012] Beneficial effects: By setting a slot in the crossbeam, the insertion part of the first connector fits tightly, preventing the first connector from rotating with the fastener when installed by the fastener, and at the same time enhancing the torsional resistance of the connected photovoltaic module.

[0013] In one optional embodiment, the photovoltaic support further includes a second connector, the diagonal brace having a first groove, the second connector being embedded in the first groove, the second connector being connected to the diagonal brace, and the second connector being connected to the inclined beam.

[0014] Beneficial effects: The connection between the inclined beam and the inclined brace is achieved by the second connector, which is embedded in the first groove of the inclined beam, thereby improving the torsional resistance of the inclined brace and the inclined beam.

The two ends of the square tube are provided with first slots. Two end caps are provided, and the two end caps are respectively connected to the two first slots. The square tube is provided with mounting holes, which are opened at the positions corresponding to the first slots. The fourth fastener passes through the mounting holes and is adapted to be fastened to the wall.

[0016] Beneficial effects: The first slot facilitates the installation and removal of the fourth fastener; the end caps at the top and bottom of the square tube prevent insects and birds from entering and also shield the fourth fastener.

[0017] In one alternative embodiment, a second groove is provided on the periphery of the square tube, and multiple second grooves are provided at intervals.

[0018] Beneficial effect: A second groove is opened on the periphery of the square tube to improve the anti-torsion and anti-rotation performance after the square tube is connected with the inclined beam and the inclined brace.

[0019] In one alternative embodiment, a second slot is provided at one end of the inclined beam, and the other end of the inclined beam is sealed.

[0020] Beneficial effects: By opening a second slot, the connection between the inclined beam and the column is facilitated; by sealing the other end of the inclined beam, insects and birds are prevented from entering the inclined beam; and the fasteners inside the inclined beam are hidden.

[0021] In one alternative embodiment, the photovoltaic support further includes a rain shield connected to the column.

[0022] Beneficial effect: By installing a rain shield, rainwater is prevented from entering the column and causing corrosion to the fasteners inside the column.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] The following is combined Figures 1 to 17 The following describes embodiments of the present invention.

[0046] According to an embodiment of the present invention, in a first aspect, a photovoltaic support is provided, comprising a column 10, a diagonal beam 20, a diagonal brace 30, a crossbeam 40, a pressure block 50, and a first fastener 61; two columns 10 are spaced apart and are adapted to be connected to a wall 110; two diagonal beams 20 are provided, and each diagonal beam 20 is connected to a column 10 in a one-to-one correspondence; two diagonal braces 30 are provided, and the two ends of each diagonal brace 30 are respectively connected to a column 10 and a diagonal beam 20, forming a triangular structure; two crossbeams 40 are spaced apart and are disposed between two diagonal beams 20, each crossbeam 40 comprising a beam body 41, an anti-slip protrusion 42, and an oblique angle 43, the oblique angle 43 and the anti-slip protrusion 42 being spaced apart, and both the oblique angle 43 and the anti-slip protrusion 42 being connected to the beam body. 41 is connected, and both ends of the beam body 41 are connected to the inclined beam 20 to form an installation space. The installation space is suitable for installing photovoltaic modules 100. The anti-slip boss 42 is suitable for abutting against the photovoltaic module 100. The pressure block 50 includes a boss part 51, a connecting part 52 and a pressing part 53. Both ends of the connecting part 52 are connected to the boss part 51 and the pressing part 53 respectively. The boss part 51 abuts against the crossbeam 40. The pressing part 53 is suitable for abutting against the photovoltaic module 100. A part of the connecting part 52 protrudes towards the crossbeam 40 to form a protruding structure 521. An inclined groove 54 is formed between the protruding structure 521 and the pressing part 53. The inclined angle 43 is correspondingly inserted into the inclined groove 54. The first fastener 61 passes through the connecting part 52 and the beam body 41 in sequence and is fastened in the beam body 41.

[0047] In this embodiment of the photovoltaic bracket, the oblique angle 43 of the crossbeam 40 is inserted into the inclined groove 54 formed between the protruding structure 521 and the pressing part 53, so that the pressing block 50 is tightly fitted with the crossbeam 40 and the photovoltaic module 100 is firmly pressed and fixed in the installation space, thus fixing the photovoltaic module 100 in the plumb direction; the anti-slip boss 42 abuts against the photovoltaic module 100 to prevent the photovoltaic module 100 from sliding down due to the tilting of the eaves; at the same time, the boss part 51 abuts against the crossbeam 40, providing a lever arm for the first fastener 61. Under the action of the tightening force of the first fastener 61, the oblique angle 43 and the inclined groove 54 are more tightly embedded, and the pressure applied by the pressing block 50 to the photovoltaic module 100 is greater, thereby improving the installation stability of the photovoltaic module 100.

[0048] Specifically, such as Figure 14 and Figure 17 As shown, the crossbeam 40 is provided with a beveled surface 45, which can weaken the light effect of the crossbeam 40's cross-sectional thickness and improve the overall aesthetics.

[0049] Specifically, in this embodiment, multiple pressure blocks 50 are spaced apart, and all multiple pressure blocks 50 are located inside the crossbeam 40, making the photovoltaic bracket look neat and beautiful.

[0050] Specifically, in this implementation, the column 10, diagonal beam 20, diagonal brace 30, crossbeam 40 and pressure block 50 are made of anodized high-strength aluminum alloy profiles, which have extremely strong corrosion resistance.

[0051] Of course, in other alternative implementations, the various components of the photovoltaic support structure can also be made of other corrosion-resistant materials, such as galvanized magnesium-aluminum high-strength thin-walled steel.

[0052] It should be noted that in this embodiment, each component of the photovoltaic support structure is provided with corresponding openings or slots to improve installation efficiency.

[0053] Specifically, the first fastener 61 includes a bolt and a nut.

[0054] Furthermore, the nut is a press-fit nut and is located on the inner wall of the crossbeam 40.

[0055] Specifically, such as Figure 8 As shown, each crossbeam 40 is equipped with two pressure blocks 50.

[0056] It should be noted that in the relevant technologies, the photovoltaic module 100 has poor stability after being installed on the photovoltaic bracket, and is prone to slipping or falling off, which poses a safety hazard. In addition, the connection between the crossbeam 40 and the diagonal beam 20 is usually fixed by welding or other methods, which makes the installation operation more complicated and makes it difficult to disassemble or maintain the photovoltaic bracket.

[0057] Therefore, in this embodiment, the boss 51 abuts against the crossbeam 40, providing a lever arm for the first fastener 61. Under the tightening force of the first fastener 61, the bevel 43 and the groove 54 are more firmly embedded, and the pressure block 50 applies greater pressure to the photovoltaic module 100, improving the installation stability of the photovoltaic module 100. At the same time, the connection between the bevel beam 20, the diagonal brace 30 and the crossbeam 40 is detachable, which facilitates installation and disassembly for maintenance.

[0058] In one embodiment, such as Figure 15 As shown, the crimping part 53 is provided with an anti-slip key 531, which is adapted to abut against the photovoltaic module 100.

[0059] Specifically, such as Figure 15 As shown, the anti-slip key 531 is shaped like a "C".

[0060] It is worth noting that by setting anti-slip keys 531 on the pressing part 53, the pressure between the pressing block 50 and the photovoltaic module 100 is increased, so that the photovoltaic module 100 is firmly fixed on the photovoltaic bracket, thereby further improving the installation stability of the photovoltaic module 100.

[0061] In one embodiment, such as Figure 6 , Figure 9 , Figure 16 As shown, the photovoltaic support also includes a first connector 70, a second fastener 62 and a third fastener 63. The second fastener 62 passes through the crossbeam 40 and is fastened to the first connector 70. The third fastener 63 passes through the inclined beam 20 and the first connector 70 in sequence and is fastened to the first connector 70.

[0062] Specifically, both the second fastener 62 and the third fastener 63 are combinations of bolts and nuts.

[0063] It is worth noting that the crossbeam 40 and the diagonal beam 20 are detachably connected by the first connector 70, the second fastener 62 and the third fastener 63, which makes disassembly and assembly simple and easy to operate.

[0064] Furthermore, such as Figure 16 and Figure 17 As shown, the first connector 70 includes a main body 71, a plug-in part 72, and a screw-in part 73. The two ends of the main body 71 are connected to the plug-in part 72 and the screw-in part 73 respectively. The crossbeam 40 has a slot 44. The plug-in part 72 is inserted into the slot 44. The second fastener 62 passes through the crossbeam 40 and is fastened to the screw-in part 73. The third fastener 63 passes through the inclined beam 20 and the main body 71 in sequence and is fastened to the main body 71.

[0065] Specifically, such as Figure 16 As shown, the insertion part 72 and the screw part 73 are both provided on the same side of the main body part 71.

[0066] Specifically, the threaded part 73 is a cylindrical structure with a threaded hole, and the second fastener 62 passes through the crossbeam 40 and is tightened into the threaded part 73.

[0067] Specifically, such as Figure 14 and Figure 17 As shown, the two ends of the inner wall of the crossbeam 40, which are spaced apart from each other, protrude into the crossbeam 40 to form a slot 44 inside the crossbeam 40.

[0068] It is worth noting that by providing a slot 44 inside the crossbeam 40, the insertion part 72 of the first connector 70 fits tightly, preventing the first connector 70 from rotating with the fastener during installation, while also enhancing the torsional resistance of the connected photovoltaic module 100.

[0069] Specifically, when connecting the crossbeam 40 and the inclined beam 20 through the first connector 70, the first connector 70 is first connected to the inclined beam 20 using the third fastener 63, and then the end of the first connector 70 with the plug-in part 72 is inserted into the crossbeam 40 and fastened by the second fastener 62.

[0070] In one embodiment, such as Figure 10 and Figure 12As shown, the photovoltaic support also includes a second connector 80. The diagonal brace 30 has a first groove 31. The second connector 80 is embedded in the first groove 31. The second connector 80 is connected to the diagonal brace 30 and to the inclined beam 20.

[0071] It is worth noting that the connection between the inclined beam 20 and the inclined brace 30 is achieved by the second connector 80. The second connector 80 is embedded in the first groove 31 of the inclined beam 20, which can improve the torsional resistance of the inclined brace 30 and the inclined beam 20.

[0072] Specifically, when connecting the diagonal brace 30 and the diagonal beam 20 through the second connector 80, the second connector 80 is first connected to the diagonal beam 20, and then the second connector 80 with the diagonal beam 20 is embedded into the first groove 31 of the diagonal brace 30 and connected to the second connector 80 by bolts.

[0073] Specifically, the second connector 80 is connected to the inclined beam 20 by bolts and a press-fit nut, with the press-fit nut located on the inner wall of the inclined beam 20.

[0074] Specifically, such as Figure 13 As shown, the second connector 80 has a rhomboid structure.

[0075] It is worth noting that the shapes and structures of the first connector 70 and the second connector 80 are easy to distinguish, which avoids installation errors between the diagonal beam 20, diagonal brace 30, and crossbeam 40, and improves installation efficiency.

[0076] In one embodiment, such as Figure 3 As shown, the column 10 includes a square tube 11, an end cap 12, and a fourth fastener 64. The square tube 11 is connected to the inclined beam 20 and the inclined brace 30 respectively. The two ends of the square tube 11 are provided with first slots 112. There are two end caps 12, which are respectively connected to the two first slots 112. The square tube 11 is provided with mounting holes 111, which are opened at the positions corresponding to the first slots 112. The fourth fastener 64 passes through the mounting holes 111 and is suitable for fastening in the wall 110.

[0077] Specifically, such as Figure 3 As shown, the end cap 12 adopts a groove design, such as Figure 6 and Figure 7 As shown, both the inclined beam 20 and the inclined brace 30 adopt the usual groove design to improve the torsional resistance of the photovoltaic bracket and enhance the aesthetic appeal of the photovoltaic bracket.

[0078] Specifically, such as Figure 11 As shown, the fourth fastener 64 is an expansion bolt.

[0079] Specifically, in this embodiment, the mounting hole 111 is an oblong hole to accommodate the installation deviation of the expansion bolt.

[0080] It is worth noting that by setting the first slot 112, it is convenient to disassemble and assemble the fourth fastener 64; the end caps 12 set at the upper and lower ends of the square tube 11 can prevent insects and birds from entering and can cover the fourth fastener 64.

[0081] In one embodiment, such as Figure 4 and Figure 5 As shown, a second groove 113 is provided on the periphery of the square tube 11, and multiple second grooves 113 are provided at intervals.

[0082] Specifically, such as Figure 4 As shown, along the extension direction of the square tube 11, six second grooves 113 are spaced apart on the outer periphery of the square tube 11.

[0083] Of course, in other alternative embodiments, the number of second grooves 113 can be adjusted according to the actual situation.

[0084] It is worth noting that a second groove 113 is provided on the periphery of the square tube 11 to improve the anti-torsion and anti-rotation performance of the square tube 11 after it is connected with the inclined beam 20 and the inclined brace 30.

[0085] In one embodiment, such as Figure 6 As shown, a second slot 22 is provided at one end of the inclined beam 20, and the other end of the inclined beam 20 is sealed.

[0086] Specifically, such as Figure 6 As shown, the other end of the inclined beam 20 is provided with an inclined beam end cap 21, which is used to seal the beam.

[0087] It is worth noting that by opening the second slot 22, the connection between the inclined beam 20 and the column 10 is facilitated. By sealing the other end of the inclined beam 20, insects and birds are prevented from entering the inclined beam 20, and the fasteners inside the inclined beam 20 are hidden.

[0088] In one embodiment, such as Figure 1 and Figure 2 As shown, the photovoltaic support also includes a rain shield 90, which is connected to the column 10.

[0089] It is worth noting that by setting up the rain shield 90, rainwater is prevented from entering the column 10 and causing corrosion to the fasteners inside the column 10.

[0090] In applying the photovoltaic bracket of this embodiment, firstly, the column 10 is fixed to the wall 110 using the fourth fastener 64; then, the first connector 70 is connected to the inclined beam 20 using the third fastener 63, and one end of the first connector 70 with the plug-in part 72 is embedded into the crossbeam 40 and fastened using the second fastener 62; next, the second connector 80 is connected to the inclined beam 20, and then the second connector 80 with the inclined beam 20 is embedded into the first groove 31 of the diagonal brace 30 and connected to the second connector 80 by bolts; then, the diagonal brace 30 and the inclined beam 20 are connected to the column 10; finally, the rain shield 90 is connected to the column 10, and the pressure block 50 is fixed to the crossbeam 40 using the first fastener 61, completing the overall installation of the photovoltaic bracket.

[0091] According to an embodiment of the present invention, in a second aspect, a photovoltaic system is also provided, including the photovoltaic bracket and photovoltaic module 100 described above, wherein the photovoltaic module 100 is disposed in an installation space and abuts against the anti-slip protrusion 42.

[0092] Although embodiments of the 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 invention, and all such modifications and variations fall within the scope defined by the invention.
