Description

Technical Field

[0001] This application relates to the field of solar energy support technology, and in particular to a connector and a photovoltaic tracking bracket. Background Technology

[0002] Rooftop distributed photovoltaic (PV) systems are mostly used on building rooftops, and the purlins and PV modules are typically secured with bolts. During bolt tightening, the mounting holes on the PV modules and purlins must first be aligned. PV modules generally weigh 30-40 kg, requiring at least two workers to lift them and locate the corresponding purlin mounting holes. However, quickly finding the correct holes on the purlins is often difficult, necessitating workers to repeatedly lift the PV modules and search for the holes for alignment. This not only results in extremely low installation efficiency but also consumes considerable physical labor.

[0026] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. The application will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0029] like Figures 1-4As shown, in a first aspect, embodiments of this application may provide a connector for connecting a purlin 5 and a photovoltaic module 5. The connector may include: a first fixing block 1, a second fixing block 2, and a connecting pin 3; the first fixing block 1 and the second fixing block 2 are respectively and independently rotatably and slidably disposed on the connecting pin 3, and the sliding direction of the first fixing block 1 and the second fixing block 2 is along the axial direction of the connecting pin 3; the connecting pin 3 is disposed through the purlin 4 and the photovoltaic module 5; the side of the first fixing block 1 facing the second fixing block 2 is used to abut against the purlin 4; the side of the second fixing block 2 facing the first fixing block 1 is used to abut against the photovoltaic module 5.

[0030] In this embodiment, during the installation process, the first fixing block 1 is first passed through the purlin 4, and then the first fixing block 1 is rotated to abut against the lower surface of the purlin 4 to complete the pre-fixing of the connector; then, when the worker installs the photovoltaic module 5, he can quickly find the installation position based on the protruding second fixing block 2, so that the second fixing block 2 passes through the photovoltaic module 5, and then rotates the second fixing block 2 to abut against the upper surface of the photovoltaic module 5, thus completing the connection between the photovoltaic module 5 and the purlin 4. The installation efficiency is extremely high, and it greatly saves the worker's physical strength and installation time.

[0031] It should be noted that in traditional technology, the fixed connection between purlin 4 and photovoltaic module 5 is generally achieved by workers moving photovoltaic module 5 onto purlin 4 and aligning the mounting holes on photovoltaic module 5 with those on purlin 4. However, photovoltaic module 5 typically weighs 30-40 kg, making it difficult to quickly align the mounting holes. This not only wastes installation time but also requires extra physical effort from workers during the repeated pushing and searching for the mounting holes, thus often taking a long time to align the mounting holes. In contrast, the connector of this application eliminates the need for on-site installation tools, allowing workers to complete the installation and fixing by hand. This significantly reduces costs and greatly improves installation efficiency. Compared to the bolt-based installation method in traditional technology, the connector of this application saves at least 50% of the time.

[0032] In an optional embodiment, a first fixing hole 11 is formed through the first fixing block 1, and a second fixing hole 21 is formed through the second fixing block 2; a connecting pin 3 passes through the first fixing hole 11 and the second fixing hole 21; a limiting member is provided on the connecting pin 3, the limiting member including a first limiting plate 31 and a second limiting plate 32, the first limiting plate 31 being located at one end of the connecting pin 3 and abutting against the first fixing block 1, and the second limiting plate 32 being located at the other end of the connecting pin 3 and abutting against the second fixing block 2. In this embodiment, both the first limiting plate 31 and the second limiting plate 32 can be circular structures, and the diameter of the first limiting plate 31 is larger than the diameter of the first fixing hole 11, and the diameter of the second limiting plate 32 is larger than the diameter of the second fixing hole 21.

[0033] In this embodiment, the connecting pin 3 is located in the first fixing hole 11 and the second fixing hole 21, which allows the first fixing block 1 and the second fixing block 2 to slide on the connecting pin 3; the first limiting plate 31 can restrict the first fixing block 1 on the connecting pin 3, so that the first fixing block 1 will not slide out of the connecting pin 3; the second limiting plate 32 can restrict the second fixing block 2 on the connecting pin 3, so that the second fixing block 2 will not slide out of the connecting pin 3, thereby enabling both the first fixing block 1 and the second fixing block 2 to slide back and forth on the connecting pin 3.

[0034] In an optional embodiment, the connecting pin 3 is provided with an external thread, and the inner wall of the first fixing block 1 forming the first fixing hole 11 is provided with a first internal thread, and the first internal thread is threadedly connected to the external thread.

[0035] In this embodiment, the first internal thread and the external thread are connected. After the purlin 4 and the photovoltaic module 5 are fixedly connected by the connector, the first fixing block 1 can be rotated so that the first fixing block 1 moves closer to the second fixing block 2 on the connecting pin 3. By shortening the distance between the first fixing block 1 and the second fixing block 2, the stability of the fixed connection between the purlin 4 and the photovoltaic module 5 is improved.

[0036] In an optional embodiment, the second fixing block 2 has a second internal thread on the inner wall of the second fixing hole 21, and the second internal thread is threadedly connected to the external thread.

[0037] In this embodiment, when the second internal thread is connected to the external thread, after the purlin 4 and the photovoltaic module 5 are fixedly connected by the connector, the second fixing block 2 can be rotated so that the second fixing block 2 moves closer to the first fixing block 1 on the connecting pin 3. By shortening the distance between the first fixing block 1 and the second fixing block 2, the stability of the fixed connection between the purlin 4 and the photovoltaic module 5 is improved.

[0038] In an optional embodiment, a first buffer pad 12 is provided on the side of the first fixing block 1 facing the second fixing block 2; and / or a second buffer pad 22 is provided on the side of the second fixing block 2 facing the first fixing block 1. The first buffer pad 12 and the second buffer pad 22 are made of elastic materials, respectively and independently. The elastic material can be rubber or silicone. Elastic materials have better stability and elasticity, which greatly improves the buffering capacity and reduces wear on the purlin 4 and the photovoltaic module 5.

[0039] In this embodiment, the arrangement of the first buffer pad 12 and the second buffer pad 22 can, on the one hand, increase the friction between the first fixing block 1 and the purlin 4, thereby improving the stability of the connection between the first fixing block 1 and the purlin 4; it can also increase the friction between the second fixing block 2 and the photovoltaic module 5, thereby improving the stability of the connection between the second fixing block 2 and the photovoltaic module 5; on the other hand, it can also reduce the damage to the purlin 4 caused by the first fixing block 1 and the photovoltaic module 5 caused by the second fixing block 2.

[0040] In an optional embodiment, a first mounting hole 41 is formed through the purlin 4, and a second mounting hole 51 is formed through the photovoltaic module 5. A first fixing block 1 passes through the first mounting hole 41 and rotates to abut against the purlin 4; a second fixing block 2 passes through the second mounting hole 51 and rotates to abut against the photovoltaic module 5. The shapes of the first fixing block 1 and the second fixing block 2 can be strip-shaped, cuboid-shaped, pentagonal, triangular, etc. When the first fixing block 1 passes through the first mounting hole 41, rotating it again will not allow it to pass through the first mounting hole 41; when the second fixing block 2 passes through the second mounting hole 51, rotating it again will not allow it to pass through the second mounting hole 51. In this embodiment, both the first fixing block 1 and the second fixing block 2 can be strip-shaped structures, and the corresponding first mounting hole 41 and second mounting hole 51 are also strip-shaped holes.

[0041] In this embodiment, the first fixing block 1 passes through the first mounting hole 41, and then the first fixing block 1 is rotated so that it is offset from the opening direction of the first mounting hole 41, thus completing the pre-installation of the connector. At this time, the second fixing block 2 protrudes on the purlin 4, which can play a positioning role. Then, the worker lifts the photovoltaic module 5 to find the position of the second fixing block 2, and then places the photovoltaic module 5 on the purlin 4. The second fixing block 2 will pass through the second mounting hole 51, and then the second fixing block 2 is rotated so that it is offset from the opening direction of the second mounting hole 51, thus completing the fixed connection between the purlin 4 and the photovoltaic module 5.

[0042] In an optional embodiment, the second fixing block 2 has a guide slope on the side facing the first fixing block 1, and the guide slope is opened in a direction away from the first fixing block 1.

[0043] In this embodiment, the connector is interference-fitted with the purlin 4 and the photovoltaic module 5. The purlin 4 and photovoltaic module 5 can only be fixedly connected after the second fixing block 2 is rotated. This interference fit also improves the stability of the fixed connection between the purlin 4 and the photovoltaic module 5. The first guide slope provides guidance for the rotation of the second fixing block 2 and reduces the difficulty of rotating it, further improving installation efficiency.

[0044] In an optional embodiment, the periphery of the first fixing block 1 and the second fixing block 2 are respectively and independently curved. The curved periphery of the first fixing block 1 and the second fixing block 2 can reduce the likelihood of hand injuries to workers.

[0045] Secondly, embodiments of this application may provide a photovoltaic tracking bracket, which includes purlins 4, photovoltaic modules 5, columns, and connectors as described in any of the above embodiments. The purlins 4 are connected to the photovoltaic modules 5 via the connectors, and the purlins 4 are connected to the columns.
