Description

Technical Field

[0001] This application relates to the field of photovoltaic module installation technology, and in particular to a positioning mechanism for photovoltaic modules and a photovoltaic device. Background Technology

[0002] Traditional photovoltaic (PV) power plants mostly use C-shaped purlins as the support structure for the bottom of PV modules. However, residential PV systems require larger purlin spans due to aesthetic considerations, and C-shaped purlins are insufficient in strength, so they are gradually being replaced by square tubular purlins. Furthermore, current residential PV systems often use pressure plates or other structures to position the bottom of the PV modules against the square tubular purlins. When there is strong wind, the PV modules are prone to vertical movement, causing the pressure plates or other structures to fail, and in some cases, the PV modules may even be blown away.

[0003] In related technologies, a medium-pressure block is used to press the top surface of the photovoltaic module, and the medium-pressure block and the pressure plate work together to position the photovoltaic module. To facilitate the installation of the medium-pressure block, the square tube purlin needs to be provided with through holes for fasteners to pass through, so that the medium-pressure block can be connected to the square tube purlin by fasteners. However, the through holes on the square tube purlin will reduce the structural strength of the purlin and also increase the processing cost. Utility Model Content

[0036] like Figure 1 and Figure 2 As shown, this application embodiment provides a positioning mechanism for a photovoltaic module. The positioning mechanism includes a first positioning component, which includes a first pressing block 200 and a first fastener 300. The first fastener 300 is installed on the purlin 101 in the form of a clamp, eliminating the need for through holes or other structures on the purlin 101 to facilitate fastener passage and avoiding the impact of through holes on the structural strength of the purlin 101. Simultaneously, when the first fastener 300 is fastened to the purlin 101, the first fastener 300 drives the first pressing block 200 to press against the top of the photovoltaic module 102, positioning the photovoltaic module 102 on the top of the purlin 101. This prevents the photovoltaic module 102 from detaching from the purlin 101 and prevents the photovoltaic module 102 from fluctuating vertically under the influence of wind in the external environment, thus improving the positional stability of the photovoltaic module 102.

[0037] The contents of this application are described in detail below with reference to specific embodiments. It should be noted that the following description is merely illustrative and not a specific limitation of this application.

[0038] In some examples, the first pressing block 200 is positioned between adjacent photovoltaic modules 102. It can be understood that the first pressing block 200 can simultaneously press down on two adjacent photovoltaic modules 102, thereby improving the positional stability of the two adjacent photovoltaic modules 102. Specifically, the first pressing block 200 presses down on the top surface of the two adjacent photovoltaic modules 102.

[0039] Furthermore, the first pressure block 200 and the first fastener 300 are two independent structures, but are movably connected. When the first fastener 300 is not yet tightened to the purlin 101, the first pressure block 200 is in a relaxed state, and at this time, the first pressure block 200 does not apply a tightening force to the photovoltaic module 102. When the first fastener 300 is tightened to the purlin 101, the first pressure block 200 is in a compressed state, and at this time, the first fastening component applies a tightening force to the first pressure block 200, which facilitates the first pressure block 200 to apply a downward pressing force to the photovoltaic module 102, thereby positioning the photovoltaic module 102.

[0040] Meanwhile, the first fastener 300 surrounds the purlin 101, which facilitates the connection of the first fastener 300 to the purlin 101 in the form of a clamp, and facilitates the matching of the positioning mechanism of this application to the square tube purlin 101. Furthermore, it eliminates the need to open through holes or other structures on the square tube purlin 101, thus ensuring the structural strength of the purlin 101.

[0041] like Figure 3 As shown, in some examples, the first fastener 300 includes a first extension 301, a bend 302, and a second extension 303, with the bend 302 located between the first extension 301 and the second extension 303.

[0042] The first pressing block 200 is located at the junction of the first extension 301 and the bend 302, or the first pressing block 200 is located at the junction of the second extension 303 and the bend 302. When the first fastener 300 is fastened to the purlin 101, the first fastener 300 applies a fastening force to the first pressing block 200 through the bend 302, thereby causing the first pressing block 200 to apply a downward pressing force to the photovoltaic module 102.

[0043] Furthermore, the first extension 301 is at an angle to the bend 302, and the second extension 303 is also at an angle to the bend 302. Specifically, the first extension 301 and the second extension 303 are parallel to each other, so that the first fastener 300 is generally formed in a "U" shape. It is understood that the "U"-shaped first fastener 300 is convenient to wrap around the outside of the purlin 101.

[0044] In some examples, both the first extension 301 and the second extension 303 are provided with a first pressure block 200. Therefore, in the positioning mechanism of this application, a single first fastener 300 is provided with two first pressure blocks 200.

[0045] Furthermore, the first pressure block 200 is installed through the first extension 301 and the first pressure block 200 is installed through the second extension 303, thereby realizing the movable connection between the first pressure block 200 and the first fastener 300.

[0046] Specifically, the first pressing block 200 is provided with a through hole 201, and the first extension 301 or the second extension 303 can pass through the through hole 201 to realize the installation of the first pressing block 200.

[0047] In some examples, the first positioning component also includes a first base plate 401. Since the "U"-shaped first fastener 300 cannot form a closed shape on its own, the first fastener 300 also needs to be connected to the purlin 101 in the form of a clamp in conjunction with the first base plate 401.

[0048] The first base plate 401 is disposed at the bottom of the purlin 101, and the first extension 301 and the second extension 303 are both connected to the first base plate 401. The first base plate 401 and the first fastener 300 together surround the outside of the purlin 101, so that the first positioning component can be fastened to the purlin 101 in the form of a clamp.

[0049] In some examples, to facilitate the connection of the first extension 301 and the second extension 303 to the first base plate 401, both the ends of the first extension 301 and the second extension 303 are threaded, and both the first extension 301 and the second extension 303 are equipped with nuts 402 that engage with the threads. During installation, the first extension 301 and the second extension 303 first pass through the first base plate 401, and the nuts 402 are installed on the protruding side. As the nuts 402 are screwed in, the area enclosed by the first fastener 300 and the first base plate 401 gradually decreases until the first base plate 401 is tightly against the bottom of the purlin 101, thereby achieving the fastening process of the first positioning component.

[0050] like Figure 4 As shown, in some examples, the first pressing block 200 includes a first pressing part 202, a first connecting part 203, and a first mounting part 204.

[0051] The first mounting part 204 is used to install the first fastener 300, that is, the through hole 201 is provided in the first mounting part 204. The first mounting part 204 is provided with a first pressing part 202 on both sides. The two first pressing parts 202 correspond to two adjacent photovoltaic modules 102 respectively, and the first pressing parts 202 are used to press the top surface of the photovoltaic module 102.

[0052] Furthermore, the first mounting portion 204 is parallel to the first pressing portion 202, and the first mounting portion 204 is connected to the first pressing portion 202 via the first connecting portion 203. It is worth noting that the first connecting portion 203 is at an angle to the first mounting portion 204, and also at an angle to the first pressing portion 202, facilitating the formation of a height difference between the first mounting portion 204 and the first pressing portion 202. Specifically, the height of the first mounting portion 204 is less than the height of the first pressing portion 202, allowing the first mounting portion 204 to be embedded in the gap between two adjacent photovoltaic modules 102, ensuring the position of the first pressing block 200 and preventing positional displacement of the first pressing block 200 during use.

[0053] In some examples, the positioning mechanism further includes a second positioning component, which includes a second pressing block 501 and a second fastener 506. The second pressing block 501 is used to press the bottom stop of the photovoltaic module 102. Since the bottom stop of the photovoltaic module 102 contacts the purlin 101, and the bottom stops of two adjacent photovoltaic modules 102 extend in different directions, it is impossible to press the bottom stops of two adjacent photovoltaic modules 102 simultaneously with a single second positioning component. Therefore, second positioning components are provided on both sides of the first positioning component, and the two second positioning components correspond to the bottom stops of adjacent photovoltaic modules 102 respectively.

[0054] Furthermore, structurally, the second fastener 506 is the same as the first fastener 300, both being fastened to the purlin 101 in the form of a clamp. However, the structure of the second pressure block 501 differs from that of the first pressure block 200.

[0055] like Figure 5 As shown, in some examples, the second pressing block 501 includes a second pressing part 502, a second connecting part 503, and a second mounting part 504. The second pressing part 502 is used to press the bottom stop of the photovoltaic module 102. The second pressing part 502 is connected to the second mounting part 504 through the second connecting part 503, and the second mounting part 504 is used to insert the second fastener 506.

[0056] The second mounting portion 504 is parallel to the second pressing portion 502, and there is a height difference between the second mounting portion 504 and the second pressing portion 502. Specifically, the height of the second mounting portion 504 is greater than the height of the second pressing portion 502. Therefore, the second connecting portion 503 is at an angle to the second pressing portion 502, and the second connecting portion 503 is also at an angle to the second mounting portion 504.

[0057] In some examples, the second pressure block 501 also includes an abutment portion 505, which is connected to the second mounting portion 504 and is at an angle to the second mounting portion 504. The abutment portion 505 abuts against the surface of the purlin 101 to ensure the stability of the second pressure block 501.

[0058] This application also provides a photovoltaic device, which includes the aforementioned positioning mechanism for photovoltaic modules.

[0059] In actual implementation, the first pressure block 200 and the first fastener 300 are positioned between adjacent photovoltaic modules 102. The first pressure block 200 is connected to the first fastener 300. When the first fastener 300 is fastened to the purlin 101, the first pressure block 200 presses down on the photovoltaic modules 102 on both sides, thereby achieving the positioning of the photovoltaic modules 102 and ensuring the fixing effect of the photovoltaic modules 102. The first fastener 300 is set around the purlin 101, which makes it easy for the first fastener 300 to be installed in the form of a clamp, without the need to set additional through holes or other features that affect the structural strength of the purlin 101, thus ensuring the overall structural strength.

[0060] Simultaneously, the second pressure block 501 is connected to the second fastener 506. When the second fastener 506 is tightened to the purlin 101, the second pressure block 501 presses down on the bottom stop of the photovoltaic module 102 on one side, further realizing the positioning of the photovoltaic module 102. Under the synergistic effect of the first positioning component and the second positioning component, the photovoltaic module 102 can fully ensure positional stability.

[0061] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
