In the photovoltaic module installation device in the prior art, the photovoltaic module is generally detachably connected to the framework by utilizing components such as a connecting piece, a fastening bolt and the like to realize the installation of the photovoltaic module, however, the scheme has the problem of low reliability in long-term use under severe environment. For example, in the photovoltaic module mounting apparatus 80 shown in fig. 1, the module frame 81 of the photovoltaic module is connected to the connecting member 82 by the fastening bolts 83, and the connecting member 82 is connected to the frame 84 by the fastening bolts 83, thereby fixing the module frame 81 to the frame 84.

In this photovoltaic module mounting apparatus 80, the fastening bolts 83 are subjected to a tensile force under the condition of leeward (wind suction) of the photovoltaic module, and when applied in a complex environment such as a large wind speed, frequent change of wind direction, long wind time throughout the year, the fastening bolts 83 are repeatedly tensioned and loosened, which has long been liable to cause loosening of nuts of the fastening bolts 83, even falling off of the photovoltaic module, and there is a problem that the mounting reliability of the photovoltaic module is poor.

In the embodiment of the application, the first connecting piece is arranged, and the first connecting piece is inserted into the first installation part and the two adjacent photovoltaic module frames in a penetrating manner along the direction different from the thickness direction of the photovoltaic module, so that the force part received by the first connecting piece is converted into shearing stress, and the first connecting piece can be abutted against the first installation part and the photovoltaic module frames, so that the installation reliability is improved.

The following describes a mounting system for a photovoltaic module according to an embodiment of the present application with reference to the drawings.

Fig. 2 is a schematic structural diagram of a mounting system of a photovoltaic module provided in an embodiment of the present application, fig. 3 is a schematic structural diagram of a cross-section of the mounting system of the photovoltaic module provided in an embodiment of the present application, fig. 4 is a schematic structural diagram of another structure of the mounting system of the photovoltaic module provided in an embodiment of the present application, and fig. 5 is a schematic exploded structural diagram of the mounting system of the photovoltaic module provided in an embodiment of the present application.

Referring to fig. 2 and 3, a photovoltaic module mounting system 100 provided in an embodiment of the present application includes a photovoltaic bracket 20 and at least two photovoltaic module frames 11.

The photovoltaic bracket 20 includes a bracket purlin 30, a mounting block 40, a first connector 50, and a second connector 60.

The mounting seat 40 is carried by the support purline 30, the mounting seat 40 is provided with a body 42 and a first mounting portion 41 protruding from the body 42, and the first mounting portion 41 is located between two adjacent photovoltaic module frames 11.

The first connecting piece 50 is partially inserted into the first mounting portion 41 and the two adjacent photovoltaic module frames 11 along the first direction F, so as to fix the first mounting portion 41 and the two adjacent photovoltaic module frames 11 relatively, and the first direction F has an included angle α with the thickness direction D of the photovoltaic module. The second connecting piece 60 is partially inserted into the bracket purline 30 and the mounting seat 40 in a penetrating manner so as to relatively fix the mounting seat 40 and the bracket purline 30.

The first mounting part 41 is arranged through the mounting seat 40, the first mounting part 41 is positioned between two adjacent photovoltaic module frames 11, a part of the first connecting piece 50 is inserted into the first mounting part 41 and two adjacent photovoltaic module frames 11 along the first direction F in a penetrating way, so that the first mounting part 41 and the two adjacent photovoltaic module 10 frames can be relatively fixed, and as the first direction F, namely the penetrating inserting direction of the first connecting piece 50 and the thickness direction D of the photovoltaic module have an included angle, under the working conditions of wind and the like of the photovoltaic module 10, the force born by the first connecting piece 50 is necessarily at least or entirely the shearing force F1 in the direction vertical to the first direction F (the extending direction of the first connecting piece 50), unlike the condition that the fastening bolt 83 is pulled along the axial direction thereof and the nut is easy to fall off, at least part or all of the first connecting piece 50 is under the stress of the shearing stress perpendicular to the first direction F, and due to the shearing stress, the first connecting piece 50 can be abutted against the first mounting portion 41 and the photovoltaic module frame 11, and even if the fastening bolt is applied to a complex wind environment, the larger the wind force is, the larger the shearing stress is, the higher the connection strength between the first connecting piece 50 and the first mounting portion 41 and the photovoltaic module frame 11 is, and the first connecting piece 50 is less easy to fall off, so that the mounting reliability of the photovoltaic module mounting system 100 of the embodiment of the application is higher.

The stress condition of the first connecting piece 50 is analyzed for the condition of the included angle α between the two different first directions F and the thickness direction D of the photovoltaic module.

Fig. 3 shows a case where the angle α is 90 °, that is, the first connector 50 receives only the shearing force F1 in the direction perpendicular to the first direction F, and in this case, even if the first connector 50 is repeatedly pressed and loosened, the shearing force F1 received by the first connector 50 is perpendicular to the extending direction of the first connector 50, so that the first connector 50 is not separated from the first mounting portion 41 and the two photovoltaic module frames 11.

In the case where the included angle α is 85 ° as shown in fig. 4, for example, when the contact area P between the first connector 50 and the first mounting portion 41 is analyzed, the reaction force F0 of the first mounting portion 41 received in the P area may be decomposed into a shearing force F1 in a direction perpendicular to the first direction F and a force F2 along the first direction F, where the shearing force F1 may press the first connector 50 against the first mounting portion 41, and even if the force is applied in a complex wind environment, the shearing stress may be increased as the wind force is increased, and the connection strength between the first connector 50 and the first mounting portion 41 and the photovoltaic module frame 11 is increased, so that the first connector 50 is less likely to fall off.

In addition, because the connection strength between the first connecting piece 50 and the photovoltaic module frame 11 and the mounting seat 40 is higher, the operation and maintenance cost can be reduced, and the photovoltaic module mounting system 100 provided by the embodiment of the application can be more suitable for use requirements in the scenes with complex wind conditions, high operation and maintenance cost, such as mountain regions, coastal beaches, even offshore and the like.

The materials of the first connector 50 and the mounting base 40 are not limited to metal, and other composite materials with higher hardness and strength can be used.

In this embodiment, referring to fig. 3, the photovoltaic module 10 may include a solar cell 12 and a photovoltaic module frame 11 connected around the solar cell 12.

The photovoltaic bracket 20 is a special structure designed for placing, installing and fixing the photovoltaic module 10 in the photovoltaic power generation system, and is a supporting mechanism for fixing the photovoltaic module 10 in a certain orientation, arrangement mode and interval by combining the geography, climate and solar resource conditions of a construction site so as to enable the whole photovoltaic power generation system to obtain the maximum power output.

In addition, referring to fig. 3 and 5, the first mounting portion 41 is located between two adjacent photovoltaic module frames 11, for example, two accommodating slots 91 may be defined by opposite sides of the first mounting portion 41 and the mounting base 40, and the two accommodating slots 91 are respectively used for carrying the two adjacent photovoltaic module frames 11.

The first connection piece 50 has a part of a structure inserted into the first mounting portion 41 and the two adjacent photovoltaic module frames 11 along the first direction F, which may mean that the part of the structure of the first connection piece 50 is inserted into the first mounting portion 41 and the two adjacent photovoltaic module frames 11, and another part of the structure of the first connection piece 50 may be outside the first mounting portion 41 and the two adjacent photovoltaic module frames 11.

Likewise, the second connection element 60 is partially configured to be inserted into the bracket purlin 30 and the mounting seat 40, so as to fix the mounting seat 40 and the bracket purlin 30 relatively, which may mean that the partial structure of the second connection element 60 is inserted into the mounting seat 40 and the bracket purlin 30, and the partial structure of the second connection element 60 may be outside the mounting seat 40 and the bracket purlin 30.

The thickness direction D of the photovoltaic module may be, for example, the thickness direction of the solar cell 12, and the first direction F and the thickness direction D of the photovoltaic module may have an angle therebetween, which means that the first direction F and the thickness direction D of the photovoltaic module do not overlap.

In particular, when the photovoltaic module is realized, the included angle alpha between the first direction F and the thickness direction D of the photovoltaic module meets the following conditions: 60.ltoreq.α.ltoreq.90 °, in other words, the first connector 50 is inserted substantially transversely into the first mounting portion 41, and the adjacent two photovoltaic module rims 11. Of course, in the case where the first direction F is perpendicular to the thickness direction D of the photovoltaic module, the connection reliability is optimal. In the embodiments of the present application, fig. 2, fig. 3, and fig. 7 to fig. 9 are all taken as examples, and the case that the included angle α is other angle is similar, and will not be described herein again.

In this embodiment, with continued reference to fig. 5, the first mounting portion 41 includes two vertical walls 411 disposed at intervals along the first direction F, and the two vertical walls 411 are provided with first plugging holes 4111 for plugging the first connector 50, and the photovoltaic module frame 11 is provided with second plugging holes 4112 for plugging the first connector 50. In this way, the first connector 50 is facilitated to penetrate into the first mounting portion 41 and the photovoltaic module frame 11.

In addition, in the prior art (refer to the fastening bolt 83 in fig. 1), two component frames 81 are connected with the connecting piece 82 at different positions through the fastening bolt 83, and the component frames 81 are thickened and widened to meet the requirements of the fastening bolt 83 on the installation space and the installation strength, which increases the size and the weight of the component frames 81, resulting in higher cost and larger occupied space. In this embodiment, because the first connecting piece 50 is inserted into the first mounting portion 41 and the two adjacent photovoltaic module frames 11 through the first inserting hole 4111 and the second inserting hole 4112, the connection between the two photovoltaic module frames 11 and the first mounting portion 41 can be realized through one first connecting piece 50, the number of connecting pieces is reduced, and the photovoltaic module frames 11 do not need to be thickened and widened, so that the size and weight of the photovoltaic module frames 11 can be reduced, and the cost is reduced.

Fig. 6 is a schematic diagram of a mounting structure of a photovoltaic module frame and a mounting seat in the mounting system of a photovoltaic module according to the embodiment of the present application.

Referring to fig. 6, the photovoltaic module frame 11 may include a frame body 111 and an extension portion 112 extending from the frame body 111, and a positioning groove 113 is formed on a side of the frame body 111 facing away from the extension portion 112, where the positioning groove 113 may be used to accommodate and support the solar cell 12. Here, unlike the prior art, the extension 112 no longer plays a role in fixing, only needs to satisfy the stress intensity, does not need to widen and thicken, does not need to open holes, and can flexibly reduce the width according to the actual situation, thereby achieving the objective of reducing the cost of the photovoltaic module frame 11.

For light weight, the second plugging hole 4112 may include two plugging sub-holes 4113 disposed on two opposite wall portions of the frame body 111, respectively, so as to facilitate the insertion of the first connector 50, a height dimension H1 of the plugging sub-hole 4113 farther from the first mounting portion 41 along the thickness direction D of the photovoltaic module, and a height dimension H2 of the plugging sub-hole 4113 closer to the first mounting portion 41 along the thickness direction D of the photovoltaic module are as follows: h1 > H2.

In the embodiment of the present application, referring to fig. 3 and 5, the first connector 50 is configured as a plate-shaped member, and the first mating hole 4111 and the second mating hole 4112 are each configured as an elongated hole. The length direction of the elongated holes is along the extending direction L of the purlins of the bracket, which facilitates more reliable fixation of the photovoltaic module 10.

In one possible embodiment, referring to fig. 2 and 3, the first connector 50 includes a first laminate board 51 and a second laminate board 52, where the first laminate board 51 penetrates at least the second plug hole 4112 of one photovoltaic module frame 11 and the first plug hole 4111 adjacent to the one photovoltaic module frame 11. The second laminated board 52 penetrates at least the second plugging hole 4112 of the other photovoltaic module frame 11 and the first plugging hole 4111 adjacent to the other photovoltaic module frame 11. In this way, the first laminated board 51 and the second laminated board 52 can be conveniently inserted into two opposite sides of the two photovoltaic modules 10, so that construction operation is facilitated.

Further, at least part of the structures of the first laminate plate 51 and the second laminate plate 52 between the two standing walls 411 are laminated to each other. The lamination areas of the first lamination plate 51 and the second lamination plate 52, which are laminated with each other, are inserted into the second insertion holes 4112 of the two photovoltaic module frames 11 and the first insertion holes 4111 of the two standing walls 411. In this way, the first laminated board 51 and the second laminated board 52 can both play a role in fixing, and in the case that one laminated board fails, the other laminated board can still play a role in fixing, so that the reliability is high.

Further, with continued reference to fig. 3, the second laminated plate 52 is partially laminated on the side of the first laminated plate 51 facing away from the main body 42, and a stopper surface 521 is further provided on the side of the second laminated plate 52 facing the main body 42, and the stopper surface 521 abuts against the insertion direction end portion of the first laminated plate 51. In this way, when the first laminated plate 51 is inserted first to the left in the drawing plane shown in fig. 3, the second laminated plate 52 can abut against the end of the first laminated plate 51 to perform a limiting function when inserted from the right in fig. 3.

Fig. 7, 8 and 9 are schematic views of three other structures of the installation system of the photovoltaic module according to the embodiment of the present application. Of the three structures, the structure of the first connecting member 50 is improved, and the rest of the structures are the same, and will not be described here again.

Referring to fig. 7, in some embodiments, the first connector 50 includes a third layer of the stack 53, the third layer of the stack 53 extending through the second mating holes 4112 of the two photovoltaic module rims 11 and the first mating holes 4111 of the two vertical walls 411. The installation operation steps can be saved compared to the case where the first connection member 50 includes the first laminate plate 51 and the second laminate plate 52.

In the embodiment shown in fig. 3 and 7, the first connection member 50 is configured as a plate-shaped member, and at this time, the photovoltaic bracket 20 further includes a positioning pin 70, where the positioning pin 70 is inserted through the first connection member 50, the body 42, and the bracket purlin 30 along a second direction, and the second direction forms an included angle with the first direction F. So configured, the first connector 50 is prevented from disengaging from the mount 40 in the first direction F. Here, the second direction may be perpendicular to the first direction F.

Further, the locating pin 70 may be located between the two standing walls 411 to make full use of space.

In particular, referring to fig. 2, 3, and 5, for example, pin holes 71 through which the positioning pins 70 pass may be formed in the first laminate plate 51, the second laminate plate 52, the body 42 of the mount 40, and the bracket purlin 30, respectively.

Further, for the extension portions 112 of the photovoltaic module frame 11, the extension portions 112 of two adjacent photovoltaic module frames 11 may be located at opposite sides of the first mounting portion 41. At least one of the opposite side edges of the first connecting member 50 along the first direction F is provided with a burring portion 54, and each burring portion 54 abuts against the corresponding extension portion 112.

The following describes the mounting steps of the mounting system 100 for a photovoltaic module according to an embodiment of the present application with reference to fig. 3 and 5:

(1) The bracket purlins 30 are mounted to other supports, such as diagonal beams.

(2) The mounting block 40 is secured to the purlin 30 by a second connector 60.

(3) The two photovoltaic module frames 11 are respectively placed in the accommodating groove 91 on the mounting seat 40, so that the two photovoltaic module frames 11 are propped against the two vertical walls 411, and the second plug holes 4112 of the photovoltaic module frames 11 are aligned with the first plug holes 4111 on the vertical walls 411.

(4) The first laminated plate 51 is sequentially pushed into the second insertion hole 4112 and the first insertion hole 4111 from the left side of the drawing of fig. 3, and after the burring 54 and the extension 112 on the first laminated plate 51 abut against each other, the second laminated plate 52 is sequentially pushed into the second insertion hole 4112 and the first insertion hole 4111 from the right side of the drawing of fig. 3 until the stopper face 521 of the second laminated plate 52 abuts against the end of the first laminated plate 51, at which time the second laminated plate 52 is pressed over the first laminated plate 51.

(5) The positions of the first laminate plate 51 and the second laminate plate 52 are adjusted so that the first laminate plate 51, the second laminate plate 52, the mounting base 40, and the pin holes 71 on the bracket purlin 30 are aligned, and the positioning pins 70 are inserted into the aligned pin holes 71.

Further, referring to fig. 8, in another possible embodiment, the first connection member 50 is configured as a screw, and the photovoltaic bracket 20 further includes a nut 501 screwed with the screw, and the head 502 and the nut 501 of the screw are respectively located on the sides of the two photovoltaic module rims 11 facing away from the standing wall 411. In this way, the photovoltaic module frame 11 and the first mounting portion 41 may be connected by a screw.

On the basis of the solution shown in fig. 8, in fig. 9, the two standing walls 411 are connected by a transverse wall 412, so that the strength of the mounting seat 40 is higher.

On the basis of the foregoing embodiments, the plugging direction of the second connector 60 is parallel to the first direction F. Similar to the first connection member 50, at least part or all of the second connection member 60 is subjected to a shear stress perpendicular to the first direction F, and due to the existence of the shear stress, the second connection member 60 can be abutted against the mounting seat 40 and the bracket purlin 30, and even if the photovoltaic module mounting system 100 is applied to a complex wind environment, the larger the wind force is, the larger the shear stress is, the higher the connection strength between the second connection member 60 and the mounting seat 40 and the bracket purlin 30 is, and the second connection member 60 is less prone to falling off, so that the mounting reliability of the photovoltaic module mounting system 100 of the embodiment of the application is higher.

Further, referring to fig. 3 and 5, the body 42 includes at least two first connecting walls 421 and the bracket purlins 30 include second connecting walls 422 spaced apart in the first direction F.
