It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0030] See also Figures 1 to 5 As shown, according to an embodiment of the present application, a photovoltaic inverter 8 bracket is provided, including: a supporting base; a bottom frame 1, the bottom frame 1 is erected on the supporting base and relatively fixed to the supporting base; a mounting frame 2, the mounting frame 2 is arranged on the side of the bottom frame 1 away from the supporting base, the mounting frame 2 is connected to the bottom frame 1 through a first support beam 4 and a second support beam 5, the first support beam 4 and the second support beam 5 intersect, and the angle between the first support beam 4 and the second support beam 5 is 60° to 90°.

[0031] The supporting foundation may be a concrete cement pier foundation or a rock foundation, etc., and this embodiment does not make any further limitation.

[0032] Specifically, in the embodiment of the present application, the photovoltaic inverter 8 is installed on the roof, and the supporting foundation is preferably a concrete cement pier foundation.

[0033] Among them, a bottom frame 1 is set up on the support foundation. When the support foundation is constructed, high-strength bolts can be pre-buried. When the bottom frame 1 is installed, the holes reserved on the bottom frame 1 are aligned with the pre-buried bolts, and then tightened and fixed with nuts.

[0034] The bottom frame 1 may be a rectangular frame made of four angle steels, channel steels or square steels.

[0035] Specifically, the bottom frame 1 is arranged horizontally, and is used to bear the gravity and other loads transmitted from the upper structure of the entire photovoltaic inverter 8 support, and evenly distribute them to the supporting foundation to improve the stability of the photovoltaic inverter 8 support.

[0036] A mounting frame 2 is provided on a side of the bottom frame 1 facing away from the supporting foundation, and the photovoltaic inverter 8 is fixed on the mounting frame 2 .

[0037] For details, see Figures 1 to 3 As shown, the installation frame 2 is arranged vertically. It is understandable that the vertically arranged installation frame 2 can, on the one hand, make full use of the vertical space, especially in places with limited space, and can more effectively layout the equipment; on the other hand, it can arrange the wires, cables and pipes in an orderly manner along the vertical direction, reduce line crossing and confusion, and facilitate maintenance and management.

[0038] Among them, a support frame is arranged between the installation frame 2 and the bottom frame 1, and the support frame is used to ensure that the installation frame 2 maintains a stable shape and position under various external forces, such as gravity and wind force, to prevent deformation, tilting or tipping.

[0039] The support frame includes a first support beam 4 and a second support beam 5, and one first support beam 4 and one second support beam 5 form a group. In the embodiment of the present application, the support frame includes two groups of first support beams and second support beams 5 that are arranged opposite to each other.

[0040] Specifically, the first support beam 4 and the second support beam 5 are symmetrically arranged with the mounting frame 2 as the symmetry center. The area surrounded by the first support beam 4, the second support beam 5 and the bottom frame 1 is a triangle, that is, the first support beam 4 and the second support beam 5 are arranged at an angle.

[0041] The angle between the first support beam 4 and the second support beam 5 may be 60° to 90°. In the embodiment of the present application, the angle between the first support beam 4 and the second support beam 5 is preferably 60°.

[0042] Specifically, the lengths of the first support beam 4 and the second support beam 5 are the same. When the angle between the first support beam 4 and the second support beam 5 is 60°, the area enclosed by the first support beam 4, the second support beam 5 and the bottom frame 1 is an equilateral triangle, which can evenly distribute the force to the three sides when subjected to external force, thereby maintaining the stability of the structure.

[0043] In some possible implementations disclosed in this application, see Figure 1 As shown, the supporting foundation includes photovoltaic cement piers 7 , and photovoltaic cement piers 7 are arranged at the four corners of the bottom of the bottom frame 1 .

[0044] Among them, the supporting foundation may include four photovoltaic cement piers 7, five photovoltaic cement piers 7 or six photovoltaic cement piers 7, etc., and this embodiment does not make further limitations.

[0045] Specifically, in the embodiment of the present application, the bottom frame 1 is a rectangular frame, and the supporting foundation is composed of four photovoltaic cement piers 7.

[0046] Among them, four photovoltaic cement piers 7 are arranged at the four corners of the bottom of the bottom frame 1 in a one-to-one correspondence.

[0047] Specifically, when four photovoltaic cement piers 7 are arranged at the four corners of the bottom of the bottom frame 1, the area of ​​the figure enclosed by the connecting lines of the four photovoltaic cement piers 7 is the largest, thereby lowering the center of gravity of the photovoltaic inverter 8 bracket and improving the stability of the photovoltaic inverter 8 bracket.

[0048] In the above embodiments, see Figure 5 As shown, the photovoltaic cement pier 7 includes a connecting bolt 71 , and at least a portion of the connecting bolt 71 extends out of the upper surface of the photovoltaic cement pier 7 .

[0049] Among them, the connecting bolts 71 can be high-strength bolts pre-buried during the construction of the photovoltaic cement pier 7.

[0050] Specifically, the connecting bolt 71 can be a U-shaped bolt, the curved section of the U-shaped bolt is located inside the photovoltaic cement pier 7, and the ends of the two straight rod sections of the U-shaped bolt away from the curved section are located outside the photovoltaic cement pier 7. In the embodiment of the present application, the ends of the two straight rod sections of the U-shaped bolt away from the curved section extend out of the upper surface of the photovoltaic cement pier 7 for connecting the bottom frame 1.

[0051] In the above embodiments, see Figure 5 As shown, a hoisting hole 72 is provided on the photovoltaic cement pier 7, and the hoisting hole 72 is located in the upper half of the photovoltaic cement pier 7, and the axis of the hoisting hole 72 coincides with the mid-plane of the photovoltaic cement pier 7. By providing the hoisting hole 72, the photovoltaic cement pier 7 can be transported by hoisting equipment, saving manpower and time, and improving the transportation efficiency of the photovoltaic cement pier 7.

[0052] The hanging hole 72 may be a through hole.

[0053] Specifically, the lifting hole 72 is located in the upper half of the photovoltaic cement pier 7, and the axis of the lifting hole 72 coincides with the median plane of the photovoltaic cement pier 7, that is, the lifting hole 72 is located directly above the center of gravity of the photovoltaic cement pier 7, so that the second-order derivative of the energy equation of the photovoltaic cement pier 7 is greater than 0, which can prevent the photovoltaic cement pier 7 from shaking or automatically flipping over when the lifting equipment is transporting the photovoltaic cement pier 7.

[0054] In the above embodiments, see Figures 1 to 3 As shown, the mounting frame 2 includes a crossbeam 21, and at least two crossbeams 21 are arranged along the vertical direction. By arranging at least two crossbeams 21, a stable mounting position is provided for the photovoltaic inverter 8, and the connection strength between the photovoltaic inverter 8 and the mounting frame 2 can be improved.

[0055] The crossbeam 21 is an angle steel, a channel steel or a square steel, etc., and this embodiment does not make any further limitation.

[0056] Specifically, the cross beam 21 extends in the horizontal direction, and two, three or four cross beams 21 may be provided, and this embodiment does not make further limitations. By providing at least two cross beams 21, the force strength of a single cross beam 21 can be reduced, and the cross beam 21 can be prevented from breaking.

[0057] In the embodiment of the present application, two cross beams 21 are provided, and the two cross beams 21 are arranged along the vertical direction.

[0058] The mounting frame 2 includes two columns that are arranged opposite to each other along the length direction of the cross beam 21 , and two cross beams 21 are arranged between the two columns.

[0059] Specifically, bolt holes are provided on the two cross beams 21 for inserting bolts to connect the photovoltaic inverter 8 .

[0060] In addition, the photovoltaic inverter 8 can also be installed in the following ways:

[0061] In some possible embodiments disclosed in the present application, a magnet is installed on the crossbeam 21, and the magnet is used to adsorb the photovoltaic inverter 8. By installing a magnet on the crossbeam 21 to adsorb the photovoltaic inverter 8, the installation time of the photovoltaic inverter 8 can be reduced and the work efficiency can be improved.

[0062] A magnet groove may be provided on the plate surface of the cross beam 21 for embedding a magnet to adsorb the photovoltaic inverter 8 .

[0063] Specifically, the magnet grooves and the magnets have the same extension direction as the crossbeam 21 , so that the photovoltaic inverter 8 can be installed at different positions of the crossbeam 21 , thereby improving the user experience.

[0064] In the above embodiments, the magnet is a neodymium iron boron magnet or a samarium cobalt magnet.

[0065] Among them, neodymium iron boron magnets and samarium cobalt magnets have stronger magnetism, can store more magnetic energy, and can maintain stable magnetism under extreme temperature and pressure conditions, thereby preventing the photovoltaic inverter 8 from falling off the mounting frame 2.

[0066] In some possible implementations disclosed in this application, see Figure 2 As shown, the photovoltaic inverter 8 bracket also includes a top frame 3, which is arranged on the side of the mounting frame 2 away from the bottom frame 1. The top frame 3 is relatively fixed to the mounting frame 2, and the top frame 3 is used to carry the sunshade 6.

[0067] The top frame 3 may be a rectangular frame.

[0068] In one embodiment, the top frame 3 is arranged horizontally; in another embodiment, the top frame 3 is arranged tilted.

[0069] Specifically, in the embodiment of the present application, the top frame 3 is fixedly arranged on the top of the mounting frame 2, and the top frame 3 is arranged horizontally, which can reduce wind resistance and improve the stability of the photovoltaic inverter 8 bracket.

[0070] Among them, the top frame 3 can be used as a keel for installing the sun visor 6, which is used to install the sun visor 6 to prevent sunlight from directly hitting the photovoltaic inverter 8, reduce the temperature increase of the photovoltaic inverter 8 caused by sun exposure, and extend the service life of the photovoltaic inverter 8.

[0071] In the above embodiment, as shown in the figure, the sunshade 6 is a corrugated plate.

[0072] The sunshade 6 may be a corrugated steel plate.

[0073] Specifically, the undulations of the corrugated shape on the sun visor 6 can, on the one hand, change the incident angle and reflection path of light, thereby more effectively blocking direct sunlight; on the other hand, it helps to drain rainwater quickly and avoid water accumulation.

[0074] The embodiment of the present application provides a photovoltaic inverter 8 bracket, wherein the mounting frame 2 is connected to the underlying frame 1 by a first support beam 4 and a second support beam 5 arranged at an angle, and is capable of bearing the weight of the photovoltaic inverter 8 and possible external forces such as wind loads and snow loads, ensuring that it will not be deformed or tipped over under various severe weather conditions; at the same time, the photovoltaic inverter 8 bracket has a simple structure, can save materials, and improve production efficiency, serving as the basis for standardized operations.

[0075] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0076] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application.
