[0065] Specifically, the first position-limiting member 32 can be connected to the fixed base 31, so that the first position-limiting member 32 can be connected to the fixed base 31 as a whole. The first position-limiting member 32 can be integrally formed with the fixed base 31, or the first position-limiting member 32 and the fixed base 31 can also be separate structures, and the first position-limiting member 32 can be fixedly connected to the fixed base 31 by bolts or welding.

[0066] For example, Figure 4 As shown, the first limiting member 32 is a limiting rod, and the limiting rod may be provided with an external thread structure. The fixed base 31 may be provided with a mounting hole. The limiting rod is passed through the mounting hole, and the limiting rod is locked with locking nuts 35 on both sides of the fixed base 31, thereby completing the installation and fixation between the first limiting member 32 and the fixed base 31.

[0069] In the embodiment of the utility model, the photovoltaic assembly 2 can be fixed in position by locking the second limit member 33, preventing the first limit member 32 from sliding out of the limit portion 711 and causing the photovoltaic assembly 2 to fall, thereby improving the installation reliability of the structure.

[0070] Specifically, the hanging structure 3 may include one, two or more first stoppers 32, and at least two stoppers 32 may be arranged at intervals along the extension direction of the fixed base 31. The number of the corresponding through slots 71 may be one, two or more.

[0072] Specifically, the first limiting member 32 is arranged in a one-to-one correspondence with the limiting portion 711 and the guiding portion 712. Figure 5 and Figure 6 The embodiment of the utility model is described by only taking the setting of two first limiting members 32 as an example.

[0073] Specifically, the hanging structure 3 may include one, two or more second limiting members 33, such as Figure 6 The embodiment of the utility model is described by taking the setting of a second limiting member 33 as an example.

[0075] Optionally, the second limit member 33 and the first limit member 32 are respectively located at the two ends of the limit portion 711 in the first direction. When the frame 7 of the photovoltaic component 2 is hung on the hanging structure 3, the shaking of the frame 7 can be reduced, the service life of each component in the photovoltaic shading system can be improved, and the reliability of installing the photovoltaic component 2 using the hanging structure 3 can be further improved.

[0076] Optionally, the structure of the second limiting member 33 may be the same as that of the first limiting member 32 .

[0077] Optionally, the fixed base 31 may be provided with a mounting hole spaced apart from the first stopper 32 along the first direction; the mounting hole is detachably connected to the second stopper 33; the maximum distance between the mounting hole and the first stopper 32 in the first direction is greater than the width of the guide portion 712 in the first direction, so that after the second stopper 33 is installed in the mounting hole, the first stopper 32 can be prevented from sliding out of the stopper 711 to the guide portion 712 under the blocking effect of the second stopper 33, thereby preventing the first stopper 32 from being separated from the frame 7 of the photovoltaic module 2, thereby improving the reliability of the installation and fixation between the hanging structure 3 and the photovoltaic module 2. Furthermore, by providing the mounting hole, the operator can directly insert the second stopper 33 into the mounting hole, which is simple to operate and improves the installation efficiency.

[0078] Specifically, the mounting hole and the first limiting member 32 are spaced apart along the first direction, and the setting direction of the mounting hole and the first limiting member 32 is consistent with the extension direction of the limiting portion 711. The mounting hole is used to be assembled with the second limiting member 33. The mounting hole can be set on the side of the first limiting member 32 close to or away from the building 1.

[0079] Optionally, the distance between the mounting hole and the building 1 is greater than the distance between the first limiting member 32 and the building. The mounting hole can be arranged on the side of the first limiting member 32 away from the building 1, so that the second limiting member 33 can be fixed on the side of the limiting member 32 away from the building 1. The second limiting member 33 and the fixed base 31 can be installed from the outside, which can improve the installation convenience of the second limiting member 33.

[0081] Optionally, the second limiting member 33 is connected to a limiting plate 34, and the limiting plate 34 is located on the side of the frame 7 away from the fixed base 31. The limiting plate 34 covers at least a portion of the limiting portion 711 and can press the frame 7 and the fixed base 31, which can further increase the reliability of the fixed connection between the second limiting member 33 and the fixed base 31, and can also tighten the frame 7 and the fixed base 31, thereby improving the reliability of the installation and fixation between the photovoltaic module 2 and the hanging structure 3.

[0082] Optionally, the limiting plate 34 can cover at least a portion of the limiting portion 711, and the length of the limiting plate 34 in at least one direction is greater than the length of the limiting portion 711 along the direction, so that the limiting plate 34 can cover the limiting portion 711. In this way, the frame 7 and the fixed base 31 can be clamped by the limiting plate 34 to fix the frame 7 and the fixed base 31, so as to avoid axial movement of the frame 7 along the second limiting member 33, thereby improving the service life of each component in the photovoltaic shading system.

[0083] Optionally, the hanging structure 3 may include fasteners; the second limiting member 33 is respectively inserted into the mounting hole and the limiting portion 711; the fasteners may be respectively connected to the second limiting member 33 and the fixed base 31 to fasten the second limiting member 33 and the fixed base 31, so as to facilitate the installation and fixation between the second limiting member 33 and the fixed base 31, and then facilitate the second limiting member 33 to block the first limiting member 32 to lock the first limiting member 32 in the limiting portion 711, so as to prevent the hanging structure 3 from being separated from the frame 7 of the photovoltaic component 2.

[0084] Specifically, an external thread structure can be provided on the second limit member 33, and the fastener can be a locking nut 35. The fastener can include two locking nuts 35. After the second limit member 33 is passed through the mounting hole on the fixed base 31, the locking nuts 35 can be used to fasten the second limit member 33 from both sides of the fixed base 31 respectively. The second limit member 33 and the fixed base 31 are tightened by the locking nuts 35, so that the installation and fixation between the second limit member 33 and the fixed base 31 can be achieved, and the second limit member 33 is convenient to be locked and unlocked, so that the second limit member 33 and the fixed base 31 are detachably connected.

[0085] Specifically, the second limiting member 33 may be provided with a first buckling member, and the corresponding fastener may be a second buckling member, so that the locking and unlocking of the second limiting member 33 can be achieved through the buckling connection between the first buckling member and the second buckling member.

[0087] In the embodiment of the utility model, the fixing plate can provide support for the first limiter 32, and the first limiter 32 can be arranged on one of the side surfaces of the fixing plate along the third direction. On the one hand, the convenience of installing and fixing the first limiter 32 and the fixing plate can be improved, and on the other hand, Figure 7As shown, both sides of the fixing plate can be installed with the frame 7 of the photovoltaic component 2 through the first limiting member 32, so that the photovoltaic components 2 can be installed and fixed on both sides of the fixing plate respectively, thereby improving the utilization efficiency of the fixing plate.

[0088] Specifically, the fixing plate may be a flat plate structure, and the shape may be a rectangular plate, a trapezoidal plate, etc.

[0089] Optionally, the fixing plate can be perpendicular to the photovoltaic module 2, and the first stopper 32 protrudes from the side of the fixing plate, which can improve the convenience of installing the first stopper 32 and the frame 7, and facilitate the limitation of the laying direction of the photovoltaic module 2. For example, the fixing plate extends horizontally so that the photovoltaic module 2 can be laid horizontally to achieve horizontal shading; the fixing plate extends longitudinally so that the photovoltaic module 2 can be laid longitudinally to achieve longitudinal shading.

[0090] Specifically, the material of the fixing plate may be steel, aluminum or organic material, etc. The fixing plate may be directly fixed to the building 1 , or may also be indirectly fixed to the building 1 .

[0091] Optionally, one end of the fixing plate is connected to the building 1 and the other end extends away from the building 1, so that the fixing plate can extend laterally, so that the photovoltaic components 2 can be laid laterally, thereby facilitating lateral shading.
