DETAILED DESCRIPTION

[0028] In order for those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the present application.

[0029] It should be noted that the terms "upper", "lower", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the auxiliary drawing, and are only for the convenience of simplifying the description of the present application, and do not indicate or imply that the device must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the scope of protection of the present application. Specifically, in the present application, the direction facing the ground is downward, and conversely, the direction away from the ground is upward, and other orientation descriptions are defined based on "upper" and "lower".

[0030] In various drawings of the present application, certain dimensions of structures or parts may be exaggerated relative to other structural parts for the convenience of illustration, and therefore, are only used to illustrate the basic structure of the subject matter of the present application.

[0031] As Figures 1 to 6As shown, the application provides a mounting mechanism 100 and a photovoltaic system, by using the mounting mechanism 100, a photovoltaic module 200 equipped with a conventional frame can be mounted on a building wall, without the need to design a frame or a flexible photovoltaic module, thereby improving the applicability of the conventional photovoltaic module 200. The mounting mechanism 100 of the application is described in detail by taking the mounting of the photovoltaic module 200 on a building body 300 as an example.

[0032] As shown in Figure 1 and Figure 2 The mounting mechanism 100 includes a mounting member 10, a load-bearing member 20, a connecting member 30, and a fixing member 40, which cooperate to quickly mount the photovoltaic module 200 on the building body 300.

[0033] Specifically, the mounting member 10 includes a mounting seat 11 for fixing on a building and a support beam 12 connected to the mounting seat 11. The mounting seat 11 and the support beam 12 are arranged at right angles, i.e., the mounting seat 11 extends in the up-down direction of the building wall, and the support beam 12 extends in the lateral direction, facilitating cooperation with the load-bearing member 20.

[0034] The mounting member 10 further includes a reinforcing portion 13 arranged at the connection between the mounting seat 11 and the support beam 12. The reinforcing portion 13 is arranged in the space enclosed by the mounting seat 11 and the support beam 12, thereby increasing the thickness of the connection between the mounting seat 11 and the support beam 12 and further increasing the structural strength of the mounting member 10.

[0035] Preferably, the thickness of the mounting member 10 is not less than the thickness of the load-bearing member 20, thereby increasing the structural strength of the mounting member 10 itself and better supporting other components of the mounting mechanism 100.

[0036] As shown in Figure 1 and Figure 2 The load-bearing member 20 includes a cross beam 21 for connecting to the support beam 12 and a vertical beam 22 extending laterally from at least one end of the cross beam 21. The vertical beam 22 is fixed to the connecting member 30, i.e., the load-bearing member 20 is used to connect the mounting member 10 and the connecting member 30.

[0037] The cross beam 21 is supported on the upper surface of the support beam 12, and the vertical beam 22 is fixed to one end or both ends of the cross beam 21 and perpendicular to the cross beam 21, i.e., the vertical beam 22 extends in the up-down direction, facilitating the installation of the connecting member 30.

[0038] Further, the length of the cross beam 21 along the extending direction of the support beam 12 is not less than the length of the support beam 12, for example, the length of the cross beam 21 is 10mm longer than the length of the support beam 12, so that the support beam 12 can better support the cross beam 21, and the cross beam 21 will not interfere with the support beam 12 when it is deformed by the force of the photovoltaic module 200, and will not affect the cooperation between the mounting member 10 and the load-bearing member 20. Of course, the length difference between the cross beam 21 and the support beam 12 needs to be determined according to the conditions of the installation site and the environmental conditions.

[0039] In the embodiment, as shown in the drawings, the vertical beam 22 is arranged at both ends of the cross beam 21 in pairs, and the vertical beam 22 includes oppositely arranged outer vertical beams 221 and inner vertical beams 222. Figure 2 The outer vertical beams 221 cooperate with the connecting member 30, and the inner vertical beams 222 are arranged in vertical alignment with the end edges of the mounting seat 11. When the mounting mechanism 100 installs the photovoltaic module 200 on the building main body 300, the inner vertical beams 222 are in close contact with the building main body 300, which on the one hand increases the contact area between the entire mounting mechanism 100 and the building main body 300, and on the other hand, when the outer vertical beams 221 are pulled by the gravity of the photovoltaic module 200, the friction between the inner vertical beams 222 and the building main body 300 can prevent the load-bearing member 20 from deforming, thereby improving the structural strength of the mounting mechanism 100.

[0040] Further, the load-bearing member 20 further includes a transition portion 23 connecting the cross beam 21 and the vertical beam 22, and the transition portion 23 is arc-shaped. When the vertical beam 22 is slightly deformed by the gravity of the photovoltaic module 200, the transition portion 23 can increase the toughness of the load-bearing member 20, avoid the vertical beam 22 being pulled hard, improve the bonding strength between the load-bearing member 20 and the connecting member 30, and further improve the overall strength of the mounting mechanism 100.

[0041] The load-bearing member 20 further includes a balance portion 24 extending laterally from the end of the pair of vertical beams 22, so that the load-bearing member 20 is in a C shape. The arrangement of the balance portion 24 can balance the wind pressure on the load-bearing member 20, thereby improving the structural strength of the mounting mechanism 10.

[0042] In the present application, the load-bearing member 20 can be in a strip shape, that is, the length direction of the load-bearing member 20 is consistent with the edge length direction of the photovoltaic module, and a plurality of mounting members 10 are arranged along the edge length direction of the photovoltaic module and cooperate with the load-bearing member 20. Of course, the load-bearing member 20 can also include a plurality of sub-load-bearing members arranged along the edge length direction of the photovoltaic module, and the load-bearing member 20 and the mounting member 10 cooperate one by one, without affecting the cooperation between the load-bearing member 20 and the mounting member 10.

[0044] As shown in the figure, Figure 5 The single connecting piece 31 includes a first base plate 311, a limiting plate 312 connected to one end of the first base plate 311, and a first clamping part 313 connected to the other end of the first base plate 311, when the single connecting piece 31 cooperates with the photovoltaic module 200, the limiting plate 312 abuts against the outer edge of the frame 201, and the first clamping part 313 clamps the bottom plate on the back of the frame 201, so as to limit and clamp the frame 201 on the single connecting piece 31, and then install the photovoltaic module 200 on the building body 300.

[0045] As shown in the figure, Figure 6 The double connecting piece 32 includes a second base plate 321 and a second clamping part 322 connected to both ends of the second base plate 321, the length of the second base plate 321 is greater than that of the first base plate 311, the second clamping part 322 and the first clamping part 313 have the same shape, and the second clamping part 322 clamps the bottom plate of the two frames 201 respectively, so as to fix the two photovoltaic modules 200 at the same time, simplify the installation steps of the photovoltaic module 200, and improve the installation efficiency.

[0046] The fixing piece 40 is used to fix the mounting seat 11 and the building body 300, the support beam 12 and the cross beam 21, and the connecting piece 30 and the vertical beam 22 respectively. Specifically, the fixing piece 40 includes a first fixing piece 41 for fixing the connecting piece 30 and the vertical beam 22, a second fixing piece 42 for fixing the support beam 12 and the cross beam 22, and a third fixing piece 43 for fixing the mounting seat 11 and the building body 300, the mounting mechanism 100 combines the components through the cooperation of the first fixing piece 41, the second fixing piece 42 and the third fixing piece 43, so as to install the photovoltaic module 200 on the building body 300.

[0047] The first fixing member 41 is used to be installed on the first substrate 311 or the middle of the second substrate 321, when the first fixing member 41 cooperates with the first substrate 311, the first fixing member 41 fixes the bottom plate of the frame 201, the connecting member 30 and the vertical beam 12 together, further strengthens the combination strength of the photovoltaic module 200 and the installation mechanism 100.

[0050] The length of the third fixing member 43 is not less than that of the support beam 12, that is, the bolt of the third fixing member 43 has sufficient length to extend into and be fixed in the building body 300. In addition, the long length of the third fixing member 43 can balance the stress of the load-bearing member 20 and the connecting member 30, improve the combination strength of the installation mechanism 100 and the building body 300, and further improve the reliability of the overall photovoltaic system.

[0051] The third fixing member 43 is preferably a chemical anchor bolt, which is glued and fixed in the hole of the building body 300 by a special chemical adhesive, so as to ensure that the installation mechanism 100 is fixed more firmly on the building body 300.
