Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 2-9, the embodiment of the utility model provides a photovoltaic module support includes: the connecting piece 13, the supporting web member 15, the fixing piece, the pile 17 and the purline 12 for installing the photovoltaic module 11; wherein, the purline 12 is fixed on the connecting piece 13; one end of the supporting web member 15 is fixed to the connecting member 13, and the other end of the supporting web member 15 is fixed to the pile 17 by a fixing member.

In the photovoltaic module support, the purline 12 is a bent member.

In the photovoltaic module bracket provided by the embodiment, the purlines 12 are fixed on the connecting pieces 13; one end of the supporting web member 15 is fixed on the connecting piece 13, and the other end of the supporting web member 15 is fixed on the pile 17 through a fixing piece, so that the force transmission path is a purline 12, the connecting piece 13, the supporting web member 15, the fixing piece and the pile 17, and compared with the force transmission path of the existing photovoltaic module support, the force transmission path is effectively shortened, and the structural stress rationality is improved; meanwhile, force transmission parts needed by the photovoltaic module support are few, the structure is simplified, and the assembling efficiency among the photovoltaic modules is improved.

It is understood that the force transmission path refers to a path for transmitting the gravity of the photovoltaic module 11.

In order to improve the support stability, the connecting members 13 are at least two and are arranged in sequence along the inclined direction of the photovoltaic module 11. Specifically, the inclined direction of the photovoltaic module 11 may be the length direction of the photovoltaic module 11, and may also be the width direction of the photovoltaic module 11.

The number of purlins 12 and supporting web members 15 is selected according to the actual need. For the convenience of installation, the purlins 12, the connecting pieces 13 and the supporting web members 15 are in one-to-one correspondence. Of course, the relationship of the number of purlins 12, connectors 13 and supporting web members 15 is other and not limited to the above.

When the number of the connecting members 13 is at least two, it is preferable that the photovoltaic module support further includes a supporting chord 14 for being disposed along an inclined direction of the photovoltaic module 11, and each connecting member 13 is fixedly connected to the supporting chord 14. Thus, stability is improved by supporting the chords 14 to connect all of the links 13 together.

It can be understood that the supporting chord 14 is configured to be disposed parallel to the photovoltaic module 11, and the length direction of the supporting chord 14 is the inclined direction of the photovoltaic module 11.

Further, the above-mentioned connecting members 13 are evenly distributed on the support chord 14.

In the photovoltaic module bracket, the supporting chord 14 is only directly connected with the connecting piece 13, the supporting chord 14 is not directly connected with the purline 12, and the supporting chord 14 is arranged along the inclined direction of the photovoltaic module 11, so that the supporting chord 14 is not in the force transmission path of the photovoltaic module bracket, that is, the supporting chord 14 is an unstressed member, the supporting chord 14 is an axial force member, and the main function of the supporting chord 14 is to reduce the degree of freedom of the whole photovoltaic module bracket. Since the support chord 14 is an axial force member, the internal force applied to the support chord 14 is uniformly distributed, and the material strength is fully utilized.

For the convenience of installation, the supporting chords 14, the purlins 12 and the supporting web members 15 are fixed to the connecting members 13 at different positions. Further, the purlins 12 and the supporting web members 15 are respectively located on both sides of the supporting chord 14.

The specific structure of the connecting piece 13 is designed according to actual needs. Preferably, the above-mentioned connecting member 13 includes: an intermediate connecting plate 132, a first connecting plate 131 fixed to a top side of the intermediate connecting plate 132, and a second connecting plate 133 fixed to a bottom side of the intermediate connecting plate 132; the purlines 12 are fixed to the first connecting plates 131, the support web members 15 are fixed to the second connecting plates 133, and the support chords 14 are fixed to the intermediate connecting plates 132.

To facilitate the connection of the purlins 12 to the supporting web members 15, the intermediate connecting plates 132, the first connecting plates 131 and the second connecting plates 133 are arranged vertically in pairs, i.e. the intermediate connecting plates 132 are perpendicular to the first connecting plates 131, the intermediate connecting plates 132 are perpendicular to the second connecting plates 133 and the first connecting plates 131 are perpendicular to the second connecting plates 133.

Preferably, the purlins 12 and the first connecting plates 131, the supporting web members 15 and the second connecting plates 133, the supporting chords 14 and the intermediate connecting plates 132 are all detachably and fixedly connected. For example, the purlins 12 and the first and second connecting plates 131, the support web members 15 and the second connecting plates 133, the support chords 14, and the intermediate connecting plates 132 are all fixedly connected by threaded connectors or snap-fit structures.

Specifically, the purlins 12 and the first connecting plates 131, the supporting web members 15 and the second connecting plates 133, the supporting chords 14, and the intermediate connecting plates 132 are all fixedly connected by bolts. The first connecting plate 131 is provided with first fixing holes 1311 for fixing the purlins 12, the second connecting plate 133 is provided with second fixing holes 1331 for fixing the support web 15, and the intermediate connecting plate 132 is provided with third fixing holes 1321 for fixing the support chords 14. The axis of the first fixing hole 1311, the axis of the second fixing hole 1331, and the axis of the third fixing hole 1321 are perpendicular to each other.

It is understood that the first fixing hole 1311, the second fixing hole 1331 and the third fixing hole 1321 are respectively for passing bolts corresponding thereto. It will be appreciated that the purlins 12 are provided in first mounting holes which are adapted to engage with the first fixing holes 1311, the support web members 15 are provided with second mounting holes which are adapted to engage with the second fixing holes 1331, and the support chords 14 are provided with fourth mounting holes 143 which are adapted to engage with the third fixing holes 1321.

The intermediate connecting plate 132, the first connecting plate 131 and the second connecting plate 133 are of an integral structure for the sake of simplifying installation. Of course, the first connecting plate 131 and the second connecting plate 133 may also be fixedly connected to the intermediate connecting plate 132 by welding or other connection methods, which is not limited in this embodiment.

In the photovoltaic module support described above, since the support chord 14 is not in the force transmission path, the size of the support chord 14, for example, the cross section of the support chord 14, can be reduced appropriately.

In order to effectively reduce the cross section of the support chord 14, it is preferable that the support chord 14 includes at least one angle iron.

The number of the angle steels is selected according to actual needs. The support chord 14 includes two angles for strength. Specifically, the two angle steels are a first angle steel 141 and a second angle steel 142, respectively, and the first angle steel 141 and the second angle steel 142 are arranged side by side. The two angle steels are positioned at the bottom side of the middle connecting plate 132 and are respectively positioned at two sides of the second connecting plate 133; or, two angles are located on the top side of the middle connecting plate 132 and located on both sides of the first connecting plate 131.

Above-mentioned connecting piece 13 is two at least and is used for when setting gradually along photovoltaic module 11's incline direction, and support web member 15 and mounting all are two at least. In order to shorten the length of the support web 15 and to reduce the amount of material used, the above-mentioned fixing elements are arranged in layers in the height direction of the pile 17. In this way, at least two support web members 15 have different heights on the pile 17, and any two support web members 15 having different heights on the pile 17 connect different connecting members 13.

In the above-mentioned photovoltaic module support, the support web member 15 is fixed on the pile through the fixing member. For the purpose of mounting, the supporting web 15 is fixed to a fixing member, which is fixed to the pile 17. Of course, the fixing elements can also be chosen to fix the support web 15 directly to the pile 17, without being limited to the above.

The specific structure of the fixing piece is selected according to actual needs. Preferably, the fixing member is a hoop 18. However, the anchor ear 18 is easy to loosen under long-term stress, resulting in poor connection reliability; the hoop 18 needs to be installed on site, so that the installation procedures are more and more complex, and the installation period is prolonged; and the anchor ear 18 needs to surround the pile 17, and the anchor ear 18 is made of steel, so that the use of the anchor ear 18 increases the steel consumption.

In order to solve the above-mentioned technical problem, the fixing member is preferably an embedded member 16 embedded in the pile 17. Because the embedded part 16 is embedded in the pile 17 in advance, the embedded part 16 is prevented from loosening, and the connection reliability is improved; the embedded parts 16 are embedded in the process of producing the pile 17, so that the embedded parts 16 do not need to be installed on site, and the installation procedures are reduced, thereby simplifying the installation procedures and shortening the installation period; meanwhile, the embedded part 16 does not need to surround the pile 17, and compared with the anchor ear 18, the material consumption can be reduced, and when the embedded part 16 is made of steel, the steel consumption is reduced.

The specific structure of the embedded part 16 is designed according to actual needs. Preferably, the embedded part 16 includes: an embedded internal member 163 embedded inside the pile 17, a first embedded outer plate 161 fixedly connected with the embedded internal member 163, and a second embedded outer plate 162 fixedly connected with the first embedded outer plate 161; the first embedded outer plate 161 is attached to the outer side wall of the pile 17, and the second embedded outer plate 162 is fixedly connected with the support web member 15.

The shape of the first embedded outer plate 161 depends on the shape of the pile 17. Specifically, when the pile 17 is a circular column, the first embedded outer plate 161 is an arc-shaped plate; when the pile 17 is a square pile, the first embedded outer plate 161 is a flat plate. The specific shape of the second embedded outer plate 162 is selected according to actual needs, for example, the second embedded outer plate 162 is a rectangular plate, which is not limited in this embodiment.

The embedded parts 16 are tightly attached to the pile columns 17, so that the attractiveness is improved, the anchoring force is increased, the supporting strength is improved, and the reliability of the whole photovoltaic module support is improved.

The second pre-buried outer plate 162 and the support web member 15 are detachably and fixedly connected to facilitate mounting and dismounting. For example, the second pre-buried outer plate 162 and the support web member 15 are fixedly connected by a screw connection, and at this time, the second pre-buried outer plate 162 is provided with a fourth mounting hole 164 for mounting the support web member 15. Specifically, the second embedded outer plate 162 and the support web 15 are fixedly connected by bolts.

The specific structure of the embedded internal member 163 is selected according to actual needs, for example, the embedded internal member 163 is an anchor bar, which is not limited in this embodiment.

In order to improve the supporting strength of the embedment 16, the first embedment outer plate 161 is welded to the embedment inner member 163.

The structure and type of the support web 15 are chosen according to the actual need. Preferably, the support web 15 is a steel tube or a C-shaped steel.

The support web 15 is typically a two-force rod and is subjected to axial forces. The bearing capacity of the support web 15 is controlled by the cross-sectional area and the radius of gyration, while the radius of gyration is greatest for a circular cross-section of the same cross-sectional area. Therefore, the support web 15 is preferably a steel pipe, which reduces the amount of steel used.

Both ends of the steel pipe are flattened portions 151 for easy installation.

It will be appreciated that the flattened portion 151 of one end of the steel tube is fixedly connected to the connecting member 13, and the flattened portion 151 of the other end of the steel tube is fixed to the pile 17 by a fixing member. For mounting and dismounting, the squashed portion 151 at one end of the steel pipe is detachably and fixedly connected with the connecting piece 13, and the squashed portion 151 at the other end of the steel pipe is detachably and fixedly connected with the fixing piece. For example, the steel pipes are fixed by bolts, i.e., the flattened portions 151 are provided with through holes through which bolts pass.

On the above-mentioned photovoltaic module support, in order to improve the support intensity, purlin 12, connecting piece 13, support chord 14, support web member 16 and mounting are the steel preferentially. Of course, the above components may be made of other materials, and are not limited to the above embodiments.
