Figure 4 A front view of a side frame provided by the present invention, Figure 5 This is a left view of a side frame provided by the present invention.

[0047] Figure 3 In order to reflect the structural relationship between the L-shaped connector, the rotating connector and the mounting bracket, Figure 3 The rotatable connector and mounting bracket are also schematically shown. In this embodiment, a photovoltaic module mounting and connection device 100 includes a plurality of photovoltaic modules arranged along a first direction X and extending along a second direction Y. Along the first direction X, the photovoltaic modules include two side frames 10 arranged opposite each other, and the side frames 10 include an outer edge surface 11 and an inner edge surface 12 arranged opposite each other, with the outer edge surface 11 adjacent to the side frame 10 of the adjacent photovoltaic module. The side frame 10 also includes at least one slot K, which extends through the outer edge surface 11 and includes a communicating opening K1 and a receiving groove body K2. The photovoltaic module mounting and connection device 100 also includes a plurality of L-shaped connectors 20 and a mounting bracket 30. One end of the L-shaped connector 20 includes an extension W, which is inserted into the receiving groove body K2 through the opening K1 of the side frame 10 of two adjacent photovoltaic modules. The other end of the L-shaped connector 20 is connected to the mounting bracket 30 via a rotatable connector 40, and the mounting bracket 30 is detachably connected to the purlin 50. The first direction X and the second direction Y intersect. The purlin 50 is located on the back of the plurality of photovoltaic modules and is connected to the plurality of photovoltaic modules to play a supporting role. The specific structure of the purlin 50 may be C-shaped steel or the like.

[0048] It is understandable that the photovoltaic module installation and connection device 100 provided in this embodiment continues to be combined with Figure 1 As shown, Figure 1Only three photovoltaic assemblies arranged along the first direction X are shown, namely the first photovoltaic assembly 200a, the second photovoltaic assembly 200b and the third photovoltaic assembly 200c. The first photovoltaic assembly 200a and the second photovoltaic assembly 200b are arranged adjacent to each other, and the second photovoltaic assembly 200b and the third photovoltaic assembly 200c are arranged adjacent to each other. Taking the first photovoltaic assembly 200a and the second photovoltaic assembly 200b as an example, the photovoltaic assembly includes two side frames 10 arranged opposite to each other along the first direction X. Along the first direction X, the first photovoltaic assembly 200a includes a first The side frame 10a and the second side frame 10b, the second photovoltaic assembly 200b includes a third side frame 10c and a fourth side frame 10d, the second side frame 10b and the third side frame 10c are adjacently arranged, the second side frame 10b and the third side frame 10c include at least one card slot K, the card slot K passes through the outer edge surface 11, the card slot K includes a connected opening K1 and a receiving groove body K2; the card slot Ka of the second side frame 10b and the card slot Kb of the third side frame 10c are arranged relative to each other, and an L-shaped connector 20 is provided, one end of the L-shaped connector 20 includes an extension W, and the L-shaped The other end of the connector 20 is connected to the mounting bracket 30 through the rotating connector 40. The extension W in the L-shaped connector 20 is inserted into the card slot Ka and the card slot Kb from the opening K1a of the second side frame 10b and the opening K1b of the third side frame 10c at the same time. The rotating connector 40 is adjusted and the L-shaped connector 20 is rotated in the gap, and the extension W is driven to move to the corresponding receiving groove body K2a and the receiving groove body K2b, so that the extension W is inserted into the receiving groove body K2a and the receiving groove body K2b through the opening K1a of the second side frame 10b and the opening K1b of the third side frame 10c at the same time. The accommodating groove body K2b plays the role of connecting and limiting the first photovoltaic component 200a and the second photovoltaic component 200b. Thereafter, the L-shaped connector 20 can be fixed by connecting the mounting bracket 30 and the purlin 50, and then the first photovoltaic component 200a and the second photovoltaic component 200b can be fixed. That is, the L-shaped connector 20 is used to simultaneously clamp two adjacent photovoltaic components to play the role of fixing the photovoltaic components, which is convenient for quick installation of photovoltaic components, reduces the gap between photovoltaic components, increases space utilization, and also prevents photovoltaic components from slipping, thereby improving the service life of photovoltaic components.

[0049] In the photovoltaic module mounting and connection device 100 provided in this embodiment, the slot K extends through the outer edge surface 11. Whether the slot K extends through the inner edge surface 12 of the corresponding side frame 10 is not limited. When the slot K extends through the outer edge surface 11 and the inner edge surface 12 of the corresponding side frame 10, the portion of the L-shaped connector 20 extending along the second direction Y is located between two adjacent photovoltaic modules, thereby limiting the left-right movement of the L-shaped connector 20 and ensuring the positional stability of the L-shaped connector 20. The case where the slot K does not extend through the inner edge surface 12 of the corresponding side frame 10 will be described in detail below.

[0050] In some optional embodiments, continue to combine Figures 1 to 5 As shown, this embodiment provides a photovoltaic module installation and connection device 100, the installation bracket 30 includes a clamp 31, the clamp 31 circumferentially clamps the purlin 50; and also includes a connecting rod 60, the connecting rod 60 extends along the first direction X, and the connecting rod 60 is used to connect the rotating connection part 40 and the other end of the L-shaped connector 20, so that there is a distance between the clamp 31 and the side frame 10 of the photovoltaic module corresponding to it.

[0051] It can be understood that the photovoltaic module mounting and connection device 100 provided in this embodiment, the mounting bracket 30 includes a clamp 31, the clamp 31 includes a first sub-section 31a and a second sub-section 31b connected to each other, one end of the first sub-section 31a and one end of the second sub-section 31b are hinged, and the other end of the first sub-section 31a and the other end of the second sub-section 31b are detachably connected by bolts. After placing the purlin 50 between the first sub-section 31a and the second sub-section 31b, the other end of the first sub-section 31a and the other end of the second sub-section 31b are connected by bolts, and the mounting bracket 30 is fixed to the purlin 50. The L-shaped connector 20 can be disassembled quickly and easily through the clamp 31, which is convenient for assembly. The photovoltaic module installation and connection device 100 provided in this embodiment further includes a connecting rod 60, which extends along the first direction X. The two ends of the connecting rod 60 are respectively connected to the rotating connection portion 40 and the other end of the L-shaped connector 20 away from the extension portion W, and are used to push the clamp 31 to the side frame 10 away from the connection, ensuring that there is a gap between the clamp 31 and the side frame 10 of the photovoltaic module it is correspondingly arranged on, thereby avoiding the problem that the clamp 31 is too close to the side frame 10 and cannot be clamped tightly with the purlin 50. Among them, the present invention does not limit the length of the connecting rod 60 in the first direction X, as long as it can ensure that there is a gap between the clamp 31 and the side frame 10 of the photovoltaic module it is corresponding to. Optionally, the length of the connecting rod 60 in the first direction X can be no more than half the length of the photovoltaic module in the first direction X. On the one hand, this can facilitate the setting of the position of the clamp 31 within this range, and on the other hand, it limits the length of the connecting rod 60 to be too long, thereby avoiding the problem of the connecting rod 60 being too long and unevenly stressed and causing breakage.

[0052] In some optional embodiments, continue to combine Figures 1 to 5 As shown, in the photovoltaic assembly installation and connection device 100 provided in this embodiment, the slot K is an L-shaped slot K.

[0053] It can be understood that in the photovoltaic module installation and connection device 100 provided in this embodiment, the slot K includes a connected opening K1 and a accommodating slot body K2, the accommodating slot body K2 is L-shaped, and the accommodating slot body K2 includes a first slot body M1 and a second slot body M2 that are connected to each other, and the second slot body M2 is also connected to the opening K1, that is, the first slot body M1 is connected to the opening K1 and the second slot body M2 respectively. Since the first slot body M1 and the opening K1 are connected, the second slot body M2 and the opening K1 do not overlap, and then the extension W of the L-shaped connector 20 can be inserted into the slot body K through the opening K1 and the first slot body M1 in turn, and then moved to the position of the second slot body M2. Since the second slot body M2 and the opening K1 do not overlap and belong to a semi-enclosed space, the second slot body M2 can play a role in engaging with the extension W, and play a role in fixing the corresponding photovoltaic module, that is, setting the slot K as an L-shaped slot K can effectively play a role in engaging the extension W and fixing the photovoltaic module.

[0054] In some optional embodiments, continue to combine Figures 1 to 5 As shown, the photovoltaic module installation and connection device 100 provided in this embodiment, the side frame 10 includes two L-shaped card slots K, the two L-shaped card slots K are arranged along the second direction Y, and the accommodating groove body K2 in the L-shaped card slot K on the same side frame 10 is located on the side of the opening K1 in the same L-shaped card slot K close to the upper edge of the photovoltaic module.

[0055] It can be understood that the photovoltaic module installation and connection device 100 provided in this embodiment, the side frame 10 includes two L-shaped slots K, and the two L-shaped slots K have the same structural orientation. On the one hand, it can simplify the process, and on the other hand, the provision of two L-shaped slots K can have a double fixing effect on the photovoltaic module. Furthermore, two L-shaped slots K on the same side frame 10 can be equidistantly provided, so that each L-shaped slot K can be subjected to equal force, thereby avoiding the problem of a certain L-shaped slot K being subjected to a greater force and causing it to fall off.

[0056] Among them, the present invention does not limit the number of L-shaped slots K on each side frame 10, nor does it limit the spacing between the L-shaped slots K. It can be specifically set according to actual conditions and will not be described in detail below.

[0057] In some optional embodiments, continue to combine Figures 1 to 5As shown, a photovoltaic module installation and connection device 100 provided in this embodiment includes two L-shaped connectors 20, and the two L-shaped connectors 20 are symmetrically arranged along the second direction Y. The two L-shaped connectors 20 are respectively a first L-shaped connector 20a and a second L-shaped connector 20b; the first L-shaped connector 20a is close to the upper edge of the photovoltaic module, and the extension W of the first L-shaped connector 20a is located on the side of the rotating connection part 40 close to the upper edge of the photovoltaic module; the second L-shaped connector 20b is close to the lower edge of the photovoltaic module, and the extension W of the second L-shaped connector 20b is located on the side of the rotating connection part 40 close to the lower edge of the photovoltaic module.

[0058] It can be understood that the photovoltaic module installation and connection device 100 provided in this embodiment includes two L-shaped connectors 20, namely a first L-shaped connector 20a and a second L-shaped connector 20b, and the first L-shaped connector 20a and the second L-shaped connector 20b are symmetrically arranged in the upper and lower directions Y, and the extension W of the first L-shaped connector 20a close to the upper edge of the photovoltaic module is arranged on the side of the rotating connection part 40 close to the upper edge of the photovoltaic module, and the extension W of the second L-shaped connector 20b close to the lower edge of the photovoltaic module is located at the side of the rotating connection part 40 close to the upper edge of the photovoltaic module. On the side close to the lower edge of the photovoltaic module; that is, the rotating connection part 40 in the first L-shaped connector 20a is arranged on the side of the extension W away from the upper edge of the photovoltaic module, and the rotating connection part 40 in the second L-shaped connector 20b is arranged on the side of the extension W away from the lower edge of the photovoltaic module, that is, the rotating connection part 40 can be arranged in the area of ​​the photovoltaic module away from the upper and lower edges, and the corresponding connected mounting bracket 30 and purlin 50 are also located in the area away from the upper and lower edges, avoiding the problem that the subsequently connected purlin 50 cannot effectively support the photovoltaic module when it is arranged close to the upper and lower edges.

[0059] In some optional embodiments, combined with Figures 1 to 3 、 Figure 5 and Figure 6 As shown, Figure 6 This embodiment provides a photovoltaic module mounting and connecting device 100 , wherein along the first direction X, a distance exists between a side surface of the slot K away from the outer edge surface 11 and the inner edge surface 12 .

[0060] It can be understood that the photovoltaic module installation and connection device 100 provided in this embodiment has a card slot K that penetrates the outer edge surface 11 along the first direction X, and the card slot K does not penetrate the inner edge surface 12 of the corresponding side frame 10, and a distance is set between the side surface of the card slot K away from the outer edge surface 11 and the inner edge surface 12, that is, when the extension W of the L-shaped connector 20 is inserted into the card slot K in two adjacent photovoltaic modules, along the first direction X, the two ends of the extension W can respectively abut the groove bottom H of the unpenetrated side frame 10 corresponding to the card slot K in the two adjacent photovoltaic modules, thereby further limiting the shaking of the L-shaped connector 20 when connecting two adjacent photovoltaic modules, and fixing the L-shaped connector 20.

[0061] Among them, the present invention does not limit the size of the distance between the side surface of the card slot K away from the outer edge surface 11 and the inner edge surface 12 along the first direction X. It is sufficient to ensure that the card slot K does not directly penetrate the inner edge surface 12 of the side frame 10 to ensure the limiting effect.

[0062] In some optional embodiments, continue to combine Figures 1 to 5 ,as well as Figure 7 、 Figure 8 As shown, Figure 7 for Figure 1 A cross-sectional view in the N-N' direction, Figure 8 for Figure 1 Another cross-sectional view in the N-N' direction.

[0063] in, Figure 6 In order to clearly illustrate the structural relationship between the L-shaped connector 20 and the slot K, only the slot K and the L-shaped connector 20 are illustrated. The specific details of other structures can be shown in conjunction with other figures. This embodiment provides a photovoltaic module installation and connection device 100, in which the L-shaped connector 20 includes a first portion 21 and a second portion 22 that are connected to each other. The end of the first portion 21 away from the second portion 22 includes an extension W, and the end of the second portion 22 away from the first portion 21 is connected to the rotating connection portion 40. The first portion 21 extends along a third direction Z, and the second portion 22 extends along a second direction Y. Along the third direction Z, the maximum depth of the slot K is less than the length of the first portion 21. The third direction Z is perpendicular to the direction of the photovoltaic module.

[0064] It can be understood that the photovoltaic module installation and connection device 100 provided in this embodiment includes an L-shaped connector 20 comprising a first portion 21 and a second portion 22 connected to each other, the first portion 21 extending along a third direction Z, and the second portion 22 extending along a second direction Y; along the third direction Z, the maximum depth of the slot K is d1, and the length of the first portion 21 is d2, and it is necessary to limit d1 to be less than d2, so that the second portion 22 is parallel to the plane where the photovoltaic module is located during installation, and then the second portion 22 can be arranged parallel to the side frame 10, which can ensure that the L-shaped connector 20 is positioned standardly and will not shake, thereby stabilizing the L-shaped connector 20; avoiding the following Figure 8 The second portion 22 is shown at an angle to the plane of the photovoltaic module, causing it to intersect with the side frame 10, preventing it from effectively securing the photovoltaic module. The present invention does not specify the maximum depth d1 of the slot K and the length d2 of the first portion 21 along the third direction Z, nor does it specify the difference between them. The only requirement is that the second portion 22 and the side frame 10 extend parallel to each other to prevent the L-shaped connector 20 from shaking.

[0065] In some optional embodiments, continue to combine Figure 1 and Figure 2 As shown, this embodiment provides a photovoltaic assembly installation and connection device 100, wherein the extension portion W is a T-shaped extension portion W.

[0066] It is understood that the photovoltaic module installation and connection device 100 provided in this embodiment has an extension portion W that is a T-shaped extension portion W. The T-shaped extension portion W includes left and right protruding portions, which can be snapped into the slots K of the side frames 10 of two adjacent photovoltaic modules, thereby simultaneously snapping the two adjacent photovoltaic modules together. The present invention does not impose any specific restrictions on the left and right protruding portions of the T-shaped extension portion W. The left and right protruding portions can be consistent in size and shape, or inconsistent, as long as they can be simultaneously inserted into the slots K of the side frames 10 of two adjacent photovoltaic modules, thereby connecting the two adjacent photovoltaic modules. Other extension portions W that meet this condition also fall within the scope of protection of the present invention.

[0067] In some optional embodiments, continue to combine Figures 1 to 3 As shown, this embodiment provides a photovoltaic assembly installation and connection device 100, wherein the rotary connection portion 40 includes a rotary rivet.

[0068] It is understandable that the photovoltaic module installation and connection device 100 provided in this embodiment has two ends of the rotating connection part 40 connected to the other end of the L-shaped connector 20 and the mounting bracket 30, respectively. Thus, the position of the L-shaped connector 20 can be adjusted by rotating the rotating connection part 40, so that it can be moved from the position of the opening K1 to the position of the accommodating groove body K2, and then two adjacent photovoltaic modules are connected and fixed through the L-shaped connector 20. Furthermore, the rotating connection part 40 includes a rotating rivet. The structure of the rotating connection part 40 is simple, easy to manufacture, and also easy to operate. However, the present invention is not limited to the structure of the rotating connection part 40 to the rotating rivet. Other structures that can adjust the position of the L-shaped connector 20 also fall within the scope of protection of the present invention.

[0069] Combine Figure 9 As shown, Figure 9 This is a flow chart of a method for installing a photovoltaic module mounting and connection device provided by the present invention. The present invention also provides a method for installing a photovoltaic module mounting and connection device, which is used to install the photovoltaic module mounting and connection device in any of the above embodiments, comprising:

[0073] Step S4: adjusting the rotating connection portion so that the L-shaped connector rotates within the gap and drives the extension portion to move to the receiving slot, so that the extension portion is simultaneously embedded in the receiving slot through the openings of two adjacent photovoltaic modules;

[0074] Step S5: Operate the mounting bracket to connect with the purlin.
