Moreover, the electric field generated by the medium-high voltage photovoltaic module is large, and the electric field generated by the medium-high voltage photovoltaic module needs to be shielded.

In order to meet the requirements, in the medium-high voltage photovoltaic power generation system, the photovoltaic bracket comprises a supporting piece and a suspension cable interweaving layer.

The support is intended to be secured to a mounting surface, which may be the surface of the ground or other object, etc. It will be appreciated that the support is perpendicular to the mounting surface.

The support pieces are multiple and support the suspension cable interweaving layers in an insulating mode. It will be appreciated that the support member and the suspension cord interweaving layer are fixedly connected and insulated. For simplifying the structure, the fixed connection structure of the supporting piece and the suspension rope interweaving layer can be selected to have insulativity.

The suspension cable interweaving layer is arranged at a certain height position of the supporting piece, so that the safety distance required by the middle-high voltage photovoltaic module can be met, and the safety distance required by the middle-high voltage photovoltaic module depends on factors such as the electric potential of an electric field generated by the middle-high voltage photovoltaic module.

The suspension cable interweaving layer is a conductive layer and is used for equipotential connection with the photovoltaic module. In this way, through equipotential connection, the suspension cable interweaving layer is a shielding layer, namely the suspension cable interweaving layer can shield an electric field generated by the photovoltaic module.

The suspension rope interweaving layer comprises a plurality of interweaved suspension ropes, and the photovoltaic module is used for being fixed at interweaving points of the suspension rope interweaving layer in an insulating mode. Since the support is used for being fixed on the mounting surface, insulation between the photovoltaic module and the mounting surface is achieved.

However, the interweaving points of the suspension interweaving layers are smaller, so that the fixing difficulty of the photovoltaic module is higher. In order to reduce the fixed degree of difficulty of photovoltaic group reduction, this application provides a fixed knot constructs for photovoltaic module.

In some embodiments, the top end surface 11 of the insulating support 1 is used for fixing the photovoltaic module, and it is understood that the top end surface 11 of the insulating support 1 is the end surface of the insulating support 1 away from the suspension wires 5, and the bottom end surface 13 of the insulating support 1 is the end surface of the insulating support 1 near the suspension wires 5. Because the top end face 11 of the insulating support piece 1 is of a face structure, the photovoltaic module is fixed on the face, and compared with the interweaving point of the photovoltaic module fixed on the suspension cable 5, the fixing difficulty of the photovoltaic module is effectively reduced. In this case, the top end face 11 of the insulating support 1 may be selected to be planar. Thus, the photovoltaic module is fixed on a plane, and the fixing difficulty of the photovoltaic module is further reduced.

Of course, the curved surface or other structure of the top end surface 11 of the insulating support 1 is only larger than the area of the interweaving points of the suspension wires 5, which is not limited in this application.

In the above-mentioned fixing structure for a photovoltaic module, the fixing member 2 may be an insulating member or a non-insulating member, and is selected according to practical situations, which is not limited in this application.

Since the fixing member 2 and the insulating support member 1 are fixedly coupled to clamp the suspension wires 5 at the interweaving positions, both the fixing member 2 and the insulating support member 1 are in contact with the suspension wires 5. In order to reduce the abrasion of the suspension cable 5, the fixing structure for the photovoltaic module optionally further comprises an upper elastic member 7 and/or a lower elastic member 4, wherein the upper elastic member 7 is arranged between the insulating support 1 and the suspension cable 5; the lower elastic member 4 is adapted to be disposed between the fixing member 2 and the suspension wire 5.

Correspondingly, the lower elastic member 4 is fixed to the fixing member 2. The fact that the lower elastic member 4 is fixed to the fixing member 2 means that the lower elastic member 4 is fixed to the fixing member 2 before the fixing member 2 and the insulating support 1 are fixedly connected. The fixing manner of the lower elastic member 4 and the fixing member 2 is selected according to the actual situation. The lower elastic member 4 is located to be convenient for fixing, and the lower elastic member 4 may be bonded to or clamped with the fixing member 2, for example, the lower elastic member 4 is fixed to the fixing member 2 by a gum layer, which is not limited in this application.

In order to more specifically describe the fixing structure for a photovoltaic module provided in the present application, three specific embodiments are provided below according to the structure of the fixing member 2 and the interweaving manner of the suspension wires 5.

Example 1

Fig. 1 to 7 show a fixing structure for a photovoltaic module according to a first embodiment.

As shown in fig. 4 and 5, two suspension wires 5 of the interweaving are sequentially distributed in the vertical direction at the interweaving position, and the suspension wire 5 at the top at the interweaving position protrudes upward. It will be appreciated that protruding upwards means protruding towards the top side of the insulating support 1. The upwardly protruding suspension wires 5 have upper protrusions 51, and the suspension wires 5 at the bottom at the interweaving positions are not protruding upwardly nor protruding downwardly. The two suspension wires 5 which are interwoven can be arranged at the same height at positions other than the interweaving positions, and the two suspension wires 5 which are interwoven can be vertically interweaved or can be interweaved at other angles, and the two suspension wires are selected according to practical situations.

In fig. 4 and 5, only two suspension wires 5 are shown interwoven. In practice, however, three or more suspension wires 5 may be selected to be interwoven, in which case one of the two suspension wires 5 located at the top adjacent at the interweaving position protrudes upward.

In order to secure the upper protruding portion 51 accommodating the suspension wires 5 and to clamp the suspension wires 5 at the interweaving positions, a fixing structure for a photovoltaic module according to the first embodiment includes: an insulating support 1, a fixing member 2, an upper auxiliary member 3, and a lower elastic member 4.

As shown in fig. 1, the height direction of the insulating support 1 is a vertical direction. The insulating support 1 is cylindrical. Of course, the insulating support 1 may be alternatively shaped, for example, rectangular parallelepiped, etc., and this is not a limitation of the present embodiment. The material of the insulating support 1 is selected according to the actual situation, and the insulating performance is ensured, and the present embodiment is not limited thereto.

The insulating support 1 is used for fixing the photovoltaic module. The top end face 11 of the insulating support 1 can be selected for fixing the photovoltaic module, which top end face 11 is planar.

The insulating support 1 has a relief structure. As shown in fig. 1 to 6, the above yielding structure includes a plurality of yielding grooves 12 for the suspension ropes 5 to pass through, all the yielding grooves 12 are intersected and communicated at the same position, and the number of the yielding grooves 12 is the same as that of the suspension ropes 5 at the interweaving positions. It will be appreciated that the relief groove 12 is provided at the bottom end of the insulating support 1. The crossing positions of all the yielding grooves 12 are the interweaving positions of the suspension ropes 5, and the suspension ropes 5 penetrate through the insulating support 1 through the yielding grooves 12.

The upper auxiliary member 3 is arranged at the bottom of the yielding through groove 12, and the upper auxiliary member 3 is used for limiting the suspension cable 5 in the vertical direction. In this way, the suspension ropes 5 positioned at the top at the interweaving positions are contacted with the upper auxiliary piece 3, and other suspension ropes 5 except the suspension ropes 5 at the top at the interweaving positions are also contacted with the upper auxiliary piece 3, so that the interweaving suspension ropes 5 are prevented from swaying upwards in the yielding through grooves 12, and the stability of the included angle suspension ropes 5 is improved. In this case, the suspension wires 5 at the interweaving position can be clamped by the insulating support 1, the upper auxiliary member 3 and the fixing member 2; if the lower elastic member 4 is provided, the suspension wire 5 at the interweaving position can be clamped by the insulating support 1, the upper auxiliary member 3, the lower elastic member 4 and the fixing member 2.

As shown in fig. 1 to 5 and 7, in order to facilitate the limiting of the suspension wire 5, the upper auxiliary member 3 includes a plurality of connection plates 31, and the connection plates 31 are in one-to-one correspondence with the relief grooves 12. All connecting plates 31 are crossed at the same position and fixedly connected, the connecting plates 31 are provided with limiting parts 32, the limiting parts 32 are positioned on one side of the connecting plates 31 close to the notch of the yielding through groove 12, the limiting parts 32 are positioned at the end parts of the yielding through groove 12, all limiting parts 32 enclose a yielding space 33, and the yielding space 33 is used for accommodating an upper protruding part 51 of the suspension cable 5 protruding upwards.

It will be appreciated that the limiting portion 32 is located at an end of the connecting plate 31 away from the crossing position, and the crossing positions of all the connecting plates 31 are the crossing positions of all the yielding grooves 12. The connecting plate 31 contacts with the bottom of the relief groove 12, the upper protruding portion 51 contacts with the connecting plate 31, and the relief space 33 is located in the above-mentioned relief structure, i.e., the relief structure indirectly accommodates the upper protruding portion 51 protruding upward from the suspension wire 5.

In order to simplify the installation, the limit portion 32 and the connection plate 31 may be selected as an integral structure. Based on this, it is also possible to choose the upper auxiliary element 3 as a single component, i.e. any two connection plates 31 as a unitary structure. Of course, the limiting portion 32 and the connecting plates 31 may be selected to be of a split type, and any two connecting plates 31 may be selected to be of a split type, which is not limited in this embodiment.

In practice, the upper auxiliary member 3 may alternatively comprise only the limiting portion 32 and not the connecting plate 31, in which case the yielding structure directly accommodates the upwardly protruding upper protruding portion 51 of the suspension cable 5, i.e. the upper protruding portion 51 contacts the bottom of the yielding channel 12.

For ease of installation, the upper auxiliary element 3 may optionally be glued to the insulating support 1, for example, the upper auxiliary element 3 is provided with a backing layer, by means of which the upper auxiliary element 3 is glued to the insulating support 1.

The upper auxiliary member 3 is in contact with the suspension wire 5, and the upper auxiliary member 3 is an elastic member in order to reduce abrasion of the suspension wire 5. In this case, the upper auxiliary member 3 is the upper elastic member mentioned above; moreover, the upper auxiliary member 3 has sealing property, and sealing between the suspension wire 5 and the insulating support member 1 can be also achieved.

The lower elastic member 4 is arranged between the fixing member 2 and the suspension cable 4, so that the abrasion of the suspension cable 5 is reduced; furthermore, the lower elastic member 4 has sealing properties, and sealing between the suspension wire 5 and the fixing member 2 can be achieved.

For ease of installation, the lower elastic member 4 may alternatively be bonded to the fixing member 2, for example, the lower elastic member 4 is provided with a backing layer, and the lower elastic member 4 is bonded to the fixing member 2 through the backing layer.

In practical situations, the upper auxiliary member 3 may be an inelastic member, or the fixing structure for a photovoltaic module may not include the lower elasticity 4, and is not limited to the structure shown in fig. 1 to 5.

The fixing member 2 is a fixing plate, and the fixing member 2 may be circular, square, or other shapes, etc., and is not limited in this embodiment according to practical situations. The shape of the lower elastic member 4 can be designed according to the shape of the fixing member 2, which is not limited in this embodiment.

The fixing piece 2 and the lower elastic piece 4 are positioned at the bottom end of the insulating support piece 1, the lower elastic piece 4 is contacted with the bottom end surface 13 of the insulating support piece 1, and the fixing piece 2 is contacted with the bottom surface of the lower elastic piece 4.

In order to improve the stability of the fixing structure for the photovoltaic module, the fixing piece 2, the lower elastic piece 4 and the insulating support piece 1 can be selected to be fixedly connected through the same screw, so that the screw sequentially penetrates through the fixing piece 2, the lower elastic piece 4 and is screwed into the insulating support piece 1, the fixing connection of the fixing piece 2, the lower elastic piece 4 and the insulating support piece 1 is realized, and meanwhile, the upper auxiliary piece 3 and the suspension cable 5 positioned at the interweaving position can be included; in addition, the whole structure can be disassembled, and the maintenance of the fixing structure for the photovoltaic module is facilitated.

It will be appreciated that as shown in fig. 1, the fixing member 2 is provided with a first mounting hole 21, and the lower elastic member 4 is provided with a second mounting hole 41; as shown in fig. 6, the bottom end surface 13 of the insulating support 1 is provided with a third mounting hole 14, and a screw is sequentially inserted through the first mounting hole 21, the second mounting hole 41, and into the third mounting hole 14.

In practical situations, other fasteners may be used instead of the screws, or other detachable fixing structures may be used instead of the screws, which is not limited in this embodiment.
