DETAILED DESCRIPTION

[0030] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] like Figure 1 As shown, an embodiment of the utility model provides a photovoltaic system, including a photovoltaic bracket 1 and a photovoltaic module 2 connected to the photovoltaic bracket 1 .

[0033] The photovoltaic support 1 includes at least two supporting positions, each of which includes a pile foundation 11, on which a column 13 is fixedly connected. For example, two pile foundations 11 are arranged in the north-south direction at a supporting position, and a column 13 is arranged on each pile foundation 11, wherein the column 13 located on the south side is low and the column 13 located on the north side is high, so that the photovoltaic module 2 is tilted to the south to face the sun, so as to obtain a better irradiation angle, which is conducive to increasing the amount of solar radiation received by the photovoltaic module 2. An inclined beam 14 is connected between the column 13 on the south side and the column 13 on the north side, and at least two purlins 12 are arranged side by side on the inclined beam 14.

[0034] Generally, the photovoltaic modules 2 in the same row can be arranged on two purlins 12 that are parallel to each other. Of course, in other examples, the photovoltaic modules 2 in the same row can also be supported by three or more purlins 12 that are arranged in parallel.

[0035] in, Figure 1 In the example of FIG. 1 , four mutually parallel purlins 12 are used to support two rows of photovoltaic modules 2. Five photovoltaic modules 2 have been installed in one row, and the sixth photovoltaic module 2 is being installed in the other row.

[0036] The number of photovoltaic modules 2 in each row can be selected according to actual needs and is not specifically limited here. By providing a plurality of photovoltaic modules 2, the power generation of the photovoltaic system is increased.

[0037] A clamping member 3 is fixedly disposed on each purlin 12 , wherein the clamping member 3 and the purlin 12 may be an integral structure or a separate structure.

[0038] Figure 2 In the example shown, the clamping member 3 is a separate structure from the purlin 12, that is, the clamping member 3 and the purlin 12 are two independent components. The clamping member 3 can be fixed to the purlin 12 by riveting, screwing, etc. Figure 2 As shown, the clamping member 3 is fixedly connected to the purlin 12 by bolts 5 .

[0039] In some embodiments, the purlin 12 can be formed by splicing multiple sections of C-shaped or I-shaped profiles through splicing pieces. The splicing pieces are formed with bolt connection holes through a budding process, and are connected to the purlin 12 only by bolts, without nuts, so that multiple sections of C-shaped or I-shaped profiles can be connected into a purlin 12, avoiding the problem that a whole long purlin 12 is inconvenient to transport to the construction site for assembly.

[0040] The bottom wall 212 of the photovoltaic module profile used for part of the photovoltaic frame 21 of the photovoltaic module 2 is provided with a connecting through hole 2121. The photovoltaic module 2 can be manually carried and installed, and the photovoltaic module 2 is carried to the photovoltaic module 2 stacking point by manual labor, and the photovoltaic module 2 is carried to the installation position of the photovoltaic bracket 1, and the photovoltaic module 2 is lifted above the photovoltaic bracket 1, and the connecting through hole 2121 is aligned with the clamping member 3, and then the photovoltaic module 2 is slowly lowered so that the clamping member 3 extends into the connecting through hole 2121, and finally the photovoltaic module 2 is pressed down with force so that the second clamping portion of the clamping member 3 passes through the connecting through hole 2121 and is clamped and matched with the first clamping portion 2101 provided on the first side wall 210 of the profile body, and thus the installation of a photovoltaic module 2 is completed.

[0041] In addition to the manual handling and installation method, the mechanical handling and installation method can also be adopted, such as the handling and installation by the unmanned vehicle 4 that can be driven automatically. The unmanned vehicle 4 that can be driven automatically can be provided with a navigation system, a visual recognition system, etc., and can move freely between the stacking point of the photovoltaic module 2 and the installation position of the photovoltaic bracket 1. The mechanical arm 41 of the unmanned vehicle 4 can be provided with a suction cup 42, and the photovoltaic module 2 is grasped by the suction cup 42, and the photovoltaic module 2 is carried to the installation position of the photovoltaic bracket 1, and the photovoltaic module 2 is lifted above the photovoltaic bracket 1, and the connecting through hole 2121 is aligned with the clamping member 3, and then the photovoltaic module 2 is slowly lowered, so that the clamping member 3 extends into the connecting through hole 2121, and finally the photovoltaic module 2 is pressed down, so that the second clamping portion of the clamping member 3 passes through the connecting through hole 2121 and is clamped and matched with the first clamping portion 2101 provided on the first side wall 210 of the profile body, so that the installation of a photovoltaic module 2 is completed.

[0042] The second clamping portion includes a clamping claw 32 .

[0043] It is not difficult to see from the above that a connecting through hole 2121 is provided on the bottom wall 212 of the photovoltaic module profile adopted by the photovoltaic frame 21, so that the second clamping portion of the clamping part 3 provided on the purlin 12 of the photovoltaic bracket 1 can pass through the corresponding connecting through hole and engage with the first clamping portion 2101, so as to complete the fixing of the photovoltaic module 2 to the purlin 12 of the photovoltaic bracket 1, thereby improving the installation efficiency of the photovoltaic system.

[0044] At least see Figure 3 As shown, the clamping member 3 provided by the embodiment of the utility model includes a base 31, which can be, for example, a flat plate, and two second connection areas are arranged side by side on the base 31, and the second connection areas can be located at both ends of the flat plate, and each of the second connection areas is provided with two claws 32, and the clamping parts of the two claws 32 are arranged back to back.

[0045] At least see also Figure 2 , Figure 3As shown, a connecting hole 33 is provided in the middle of the flat plate, and the clamping member 3 can be fixed to the purlin 12 by means of a bolt 5 passing through the connecting hole 33 .

[0046] In other examples, the clip 3 may be fixed to the purlin 12 by means of rivets passing through the connection holes 33 .

[0047] See also Figure 2 As shown, the above-mentioned clamping member 3 is provided with two second connection areas, and the same clamping member 3 can be connected to two adjacent photovoltaic modules 2. For example, for two adjacent photovoltaic modules 2, the clamping claw 32 of one of the second connection areas of the base 31 is clamped and matched with the first clamping portion 2101 of one photovoltaic module 2, and the clamping claw 32 of the other second connection area of ​​the base 31 is clamped and matched with the first clamping portion 2101 of the other photovoltaic module 2.

[0048] Of course, in other examples, one claw 32 may be provided at each first connecting area.

[0049] At least see Figure 1 , Figure 2 As shown, the photovoltaic module 2 provided in the embodiment of the utility model includes a photovoltaic frame 21 and at least one photovoltaic component 22. The photovoltaic component 22 is connected to the photovoltaic frame 21. As an implementable method, the edge of at least one side of the photovoltaic component 22 is embedded in the first groove 2114 of the photovoltaic component profile adopted by the photovoltaic frame 21.

[0050] Specifically, the photovoltaic frame 21 includes: at least two parallel photovoltaic module profiles, the photovoltaic module profiles extend along a first direction, and at least two parallel second profiles, the second profiles extend along a second direction. The first direction intersects with the second direction, and the angle of intersection between the two can be determined according to actual conditions. For example, if the photovoltaic module 22 used is a rectangle, the angle at which the second direction intersects with the second direction is 90°; if the photovoltaic module 22 used is a regular hexagon, the angle at which the second direction intersects with the second direction is 120°.

[0051] Figure 1 In the example shown, the angle at which the second direction intersects the second direction is 90°, that is, the photovoltaic frame 21 is a rectangular frame. The long side of the rectangular frame is made of photovoltaic module profiles.

[0052] The photovoltaic module profile and the second profile may be of the same structure or of different structures. For example, when using profiles of different structures, the photovoltaic module profile and the second profile may have the same general structure, except that the bottom wall 212 of the second profile does not have a connecting through hole 2121.

[0053] Regardless of whether the photovoltaic module profile and the second profile adopt the same structure, both are provided with a first groove 2114, wherein the openings of the first grooves 2114 of the two edge photovoltaic module profiles are arranged facing each other, and the openings of the first grooves 2114 of the two second profiles are also arranged facing each other. In this way, the two first grooves 2114 on the two edge photovoltaic module profiles and the two first grooves 2114 on the two second profiles are enclosed to form an installation groove.

In addition, m can be greater than n, or m can be less than n, for example, m=10-13, m can specifically be 10, 11, 12, or 13, and correspondingly, n=5-7, n can specifically be 5, 6, or 7.

At the same time, the area of ​​the battery cell is larger than that of the traditional battery cell, and the spacing between the battery cells is smaller, which can improve the power generation efficiency of the photovoltaic module 22.
