Description

Photovoltaic array support and connecting assembly thereof

Technical Field

The utility model relates to a photovoltaic array support, in particular to a coupling assembling for photovoltaic array support.

Background

In photovoltaic power generation systems, photovoltaic array mounts, such as flat single axis tracking mounts, are often used. Taking a flat single-axis tracking support as an example, because the support can track the change of the azimuth angle of the sun in the daytime, the annual power generation total amount of the photovoltaic module adopting the flat single-axis tracking support is 15-25% higher than the annual power generation total amount of the photovoltaic module adopting the optimal fixed inclination angle support. In general, the tracking rotating part of the flat single-shaft tracking bracket is provided with a main beam in the north-south direction. Photovoltaic modules are generally mounted on a main beam, and the main beam is supported by a plurality of columns arranged in the north-south direction. Because the main beam is longer in the north-south direction, the main beam is generally required to be divided into a plurality of sections, and the sections are connected through connecting components. The rotating arm driving the main beam to rotate is usually arranged in the middle or at one end of the main beam. The connecting assembly for connecting the main beam sections generally adopts an upper hoop and a lower hoop, the center of the connecting assembly is arranged at the joint or gap position of the two main beam sections, the main beam sections at the left end and the right end are clamped by fasteners, and then the two main beam sections are connected, so that the north-south center of the connecting assembly is always kept at the joint of the two main beam sections, and the bending moment and the torque can be effectively transmitted between the two main beam sections.

However, the connection assembly and the main beam are not limited and blocked along the axial direction of the main beam, and the axial slippage is completely realized by the friction force generated by the clamping of the connection assembly and the main beam.

The inventor finds that when the girder is in a static state, the friction force can completely ensure that the axial movement is not generated between the connecting assembly and the girder, but the girder of a flat single shaft needs to track and rotate along the north-south axis when working, the connecting assembly also needs to transmit the radial alternating torque generated by the east-west rotation, therefore, in actual conditions, the fastening degree is not enough or torsional vibration causes the loosening of the fastening piece and other reasons during installation, the connecting assembly can generate the unidirectional sliding along the axial direction, the girder connection can be caused to fall off in a long time, and the tracking support is damaged.

Fig. 1 and 2 show an example of a photovoltaic array support 100, wherein the photovoltaic array support 100 is exemplified by a single flat axis tracking support. The photovoltaic array support 100 has a main beam 102 extending in a north-south direction (as an example of an "axial direction"). The main beam 102 is rotatably supported by the columns 101 arranged in the north-south direction, for example, by a rotating shaft. Photovoltaic modules 200 are laid on the main beams 102. The driven wheel 103 is connected with the main beam 102, and when the driven wheel 103 rotates, the main beam 102 rotates along with the driven wheel 103, so that the photovoltaic module 200 can rotate along with the main beam 102 towards the east and west directions, and illumination can be received at a better angle. For example, driven wheel 103 may be driven by a motor, which is controlled by a corresponding control signal. The main beam 102 is long in the north-south direction and is divided into several sections, each of which may be referred to as a main beam section, which will be described later, and the main beam sections are connected by the connecting assembly 1. In other words, the photovoltaic array support 100 comprises a plurality of spar segments distributed along the axial direction, the connection assembly 1 connecting adjacent spar segments of the plurality of spar segments.

It is to be understood that these and other drawings are merely exemplary and are not to scale, and should not be considered as limiting the scope of the invention. In addition, for convenience of description, spatial relational terms such as "lower", "upper", and the like may be used herein to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that these terms of spatial relationship are intended to encompass other orientations of the element or feature in use or operation in addition to the orientation depicted in the figures. For example, if an element in the figures is turned over, elements described as "below" other elements or features would then instead be oriented "above" the other elements or features. Thus, the exemplary words "below" and "beneath" can encompass both an orientation of up and down. Other orientations of the elements are possible (rotated 90 degrees or at other orientations) and the spatial relationship descriptors used herein should be interpreted accordingly.

Fig. 3, 4, 5 and 6 show the fitting relationship of the connecting assembly 1 and the main beam 102 according to the present invention. The connection assembly 1 is used to connect

adjacent spar segments

102a, 102 b. Fig. 3 and 4 are perspective views, particularly of fig. 4, showing

adjacent spar segments

102a, 102b with an axial gap S (otherwise known as a seam) between

adjacent spar segments

102a, 102 b. Fig. 5 and 6 are a side view and a top view of the upper band 21, which will be described later, taken away, respectively.

The connecting assembly 1 comprises a hoop 2. The anchor ear 2 has an inner side 2a by means of which the

adjacent girder segments

102a, 102b are frictionally connected. The anchor ear 2 also has anti-slip projections 2b (shown in fig. 4) projecting inwardly from the inner side face 2 a. The anti-slip projection 2b is intended to project into the axial gap S between

adjacent spar sections

102a, 102 b. Although described later, in the illustrated embodiment, the anti-slip projection 2b is provided by the anti-slip stopper 3 and is a part of the anti-slip stopper 3. However, it should be understood that the anti-slip protrusions 2b may be provided as protrusions protruding inward from any position of the inner side surface 2a of the hoop 2, for example, the anti-slip protrusions 2b may be integrally formed with the inner side surface 2a of the hoop 2, as long as the anti-slip protrusions 2b can protrude between the adjacent

main beam sections

102a, 102b to perform the anti-slip function.

In fig. 3, the hoop 2 comprises an upper hoop member 21 and a lower hoop member 22, and the upper hoop member 21 and the lower hoop member 22 are connected by a fastener 23 to form an inner side 2a encircling the adjacent

main beam sections

lower hoop members

21 and 22 and providing an anti-slip protrusion 2 b.

In fig. 3 and 4, the upper and

lower hoop members

21 and 22 have mounting

ears

21a and 22a, respectively, and the anti-slip stopper 3 is clamped by the mounting

ears

21a and 22a, and the fastening member 23 is coupled to the mounting

ears

21a and 22 a. The mounting

ears

21a, 22a have screw holes 26 through which bolts as the fasteners 23 pass. In the embodiment shown in fig. 6, the upper hoop 21 (not shown in fig. 6) and the lower hoop 22 each have mounting ears, such as mounting ears 22a, on both sides of the

main beam segments

102a, 102b for fasteners 23 to pass through. Referring to fig. 3 and 6, the upper hoop member 21 and the lower hoop member 22 are two separate members, the upper hoop member 21 and the lower hoop member 22 are coupled after being closed, the upper hoop member 21 and the lower hoop member 22 are both frame-door-shaped, and both ends of the upper hoop member 21 and the lower hoop member 22 are bent outward to form a mounting ear 21a and a mounting ear 22a respectively. It should be understood that the upper 21 and lower 22 hoops may also be integrally formed on one side of the

main beam segments

102a, 102b, with the mounting

ears

21a, 22a shown in FIG. 6 on the other side of the

main beam segments

102a, 102 b. In other words, the upper hoop member 21 and the lower hoop member 22 may be two parts of the integrally formed hoop 2, respectively.

With continued reference to fig. 3 and 4, the connection assembly 1 may include a plurality of fasteners 23. Some of the fasteners 23, such as the fasteners 23a, only pass through the mounting ears 21a of the upper hoop member 21 and the mounting ears 22a of the lower hoop member 22, and some of the fasteners 23, such as the fasteners 23b, pass through the mounting ears 21a of the upper hoop member 21, the anti-slip stopper 3 and the mounting ears 22a of the lower hoop member 22 in sequence, so that the anti-slip function is better achieved. In another embodiment, the fasteners 23 may all only penetrate through the mounting

ears

21a and 22a of the upper and

lower hoops

21 and 22, for example, two of the fasteners 23 may be disposed on both sides of the anti-slip stopper 3 along the axial direction D0. Or, the fastening pieces 23 all penetrate through the mounting ears 21a of the upper hoop member 21, the anti-slip stopper 3 and the mounting ears 22a of the lower hoop member 22 in sequence.

Referring to fig. 5 and 6, the anti-slip stopper 3 is provided at a central position of the coupling assembly 1 in the axial direction D0. In fig. 5 and 6, the anti-slip projection 2b is provided at the center of the anti-slip stopper 3 in the axial direction D0.

In the illustrated embodiment, the anti-slip stopper 3 is flat. Fig. 7 and 8 show an example profile of the flat anti-slip stopper 3. The anti-slip stopper 3 includes a rectangular body 31 having a long side 31a and a short side 31 b. The anti-slip stopper 3 further comprises a screw hole 32 penetrating through the rectangular body 31, and the screw hole 32 can play a role in positioning. The anti-slip projections 2b project from the long sides 31a, in other words, the anti-slip projections 2b are projections projecting from the long sides 31a of the rectangular body 31 of the anti-slip stopper 3. In fig. 7 and 8, the anti-slip projections 2b protrude from the center of the long side 31 a. The whole anti-slip block 3 is an axisymmetric component. Fig. 8 differs from fig. 7 in that the rectangular body 31 has rounded corners 31c at the four corners, similar to an elliptical configuration.

In the illustrated embodiment, the anti-slip stopper 3 is disposed at the position of the north-south center line of the connecting assembly 1, taking a flat single-axis tracking bracket as an example. The two screw holes 32 on the anti-sliding stop block 3 are aligned with the screw holes on the two sides of the north-south central line of the connecting component 1, and the anti-sliding convex part 2b is embedded in the axial gap S between the two

main beam sections

102a and 102b towards the main beam direction. When the hoop 2 is fastened by the fastening piece 23, the middle two bolts sequentially pass through the screw hole 26 of the upper hoop member 21, the screw hole 32 of the anti-slip stopper 3 and the screw hole 26 of the lower hoop member 22, and the other bolts sequentially pass through the screw hole 26 of the upper hoop member 21 and the screw hole 26 of the lower hoop member 22.

When the main beam 102 causes the connecting component 1 to slide radially to one side under the action of the alternating torque, the fastener 23 on the connecting component 1 can drive the anti-sliding stop block 3 to slide, and the anti-sliding convex part 2b is embedded in the gap between the two

main beam sections

102a and 102b, so that the anti-sliding stop block 3 can be blocked by the end surface of the main beam when sliding to any side, thereby achieving the purpose of preventing the connecting component from sliding.

The anti-sliding convex part is arranged in the connecting assembly, and particularly the anti-sliding stop block is arranged to provide the anti-sliding convex part, so that the structure is simple, the manufacturing and the installation are simple and convenient, the cost is low, and the reliability is high. If the method of welding the stop block or opening the screw hole on the main beam is adopted to prevent the axial sliding of the connecting assembly, the processing cost is high and the efficiency is low due to the long and large main beam, which is very uneconomical. Compared with the anti-sliding method, the anti-sliding convex part is arranged in the connecting component, so that the main beam does not need to be additionally processed, and the connecting component can be ensured not to axially slide.

Along with the popularization and application of the flat single-axis tracking technology in the construction of photovoltaic power stations, the anti-slip convex part is arranged in the connecting assembly to serve as an effective measure for improving the performance of the flat single-axis tracking support, and the flat single-axis tracking support has a wide application prospect in the construction of future photovoltaic power stations.

It should be understood that although the illustrated embodiment is exemplified by a flat single axis tracking support, the connection assembly described above may also be applied to other photovoltaic array supports such as fixed supports, manually adjustable supports.

Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. For example, the conversion methods in the different embodiments may be combined as appropriate. Therefore, any modification, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention, all without departing from the content of the technical solution of the present invention, fall within the scope of protection defined by the claims of the present invention.
