Description

Technical Field

[0001] The utility model relates to the technical field of new energy, and in particular to an anti-slip installation component for a photovoltaic frame and a photovoltaic system. Background Art

[0002] Solar photovoltaic power generation is an important technological alternative for decarbonization plans. However, the increasingly harsh environmental conditions that photovoltaic modules will face in the future will have a significant impact on the orderly development of the photovoltaic industry. As a key component of solar energy systems, photovoltaic frames are crucial for the safe and reliable operation of photovoltaic modules. Compared to aluminum frames, steel frames offer the advantages of high mechanical strength and low cost, better meeting the needs of the photovoltaic industry.

[0003] However, steel frames have poorer plasticity than aluminum frames during their production process, and the friction on the surface of steel frames is relatively small. Therefore, steel frames cannot achieve a good anti-slip effect by adopting a pressing block installation structure with anti-slip stripes (also known as anti-slip teeth or dense tooth structure) to achieve stable and firm installation of photovoltaic frames and photovoltaic modules. Due to the high wind pressure and snow pressure during outdoor use, if the pressing block installation structure with anti-slip stripes is continued to be used like the aluminum frame, it will easily cause the steel frame to slip or deviate from the pressing block installation structure during outdoor use, causing the photovoltaic modules installed in the steel frame to slip and tilt along with the steel frame. Therefore, how to ensure the safety and reliability of steel frames and photovoltaic modules during actual outdoor installation and use has become a focus of attention for industry personnel.

[0004] In response to the above situation, the existing technology, such as a photovoltaic module steel frame mounting structure provided by publication number CN219802245U, is a structure in which a frame pressing block is arranged on the outer side of the steel frame according to the bending shape of the steel frame, and a fixing block is provided below the frame pressing block. The frame pressing block is fixed to the mounting platform of the photovoltaic module by bolts through the fixing block, thereby solving the risk of the existing steel frame being easily detached from the frame under stress. However, this photovoltaic module steel frame mounting structure has the following defects: the frame pressing block used is only applicable to the case where there is a protrusion (such as a trapezoidal protrusion) on the A side of the steel frame (i.e., the top surface of the steel frame). If there is no protrusion on the A side of the steel frame, the frame pressing block will not be able to play a stable and reliable role of firm fixation, and therefore cannot be adapted to all types of steel frames on the market. At the same time, when subjected to excessive wind pressure and snow pressure, the steel frame and the photovoltaic module may slip out of the frame pressing block along the length extension direction of the steel frame (corresponding to the length extension direction of the trapezoidal protrusion).

DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0029] Example

[0030] A photovoltaic system of this embodiment includes a photovoltaic module and an anti-slip installation module; see Figure 1 The photovoltaic module includes a photovoltaic laminate 1 and a photovoltaic frame 2. The photovoltaic frame 2 includes a first mounting cavity 21 and a second mounting cavity 22 located below the first mounting cavity 21. The side of the photovoltaic laminate 1 is mounted within the first mounting cavity 21. In practice, a sealant is injected into the first mounting cavity 21 to ensure a secure connection with the side of the photovoltaic laminate 1. The anti-slip mounting assembly is used to securely attach the second mounting cavity 22 of the photovoltaic frame 2 to the external mounting member 6.

[0031] A photovoltaic frame 2 anti-slip installation assembly of this embodiment, see Figure 1-2, including a support plate 3 and a crimping assembly 4 fixedly mounted on an external mounting member 6 (such as a beam). The support plate 3 is arranged on the lower surface of the bottom of the second mounting cavity 22, and the lower surface of the support plate 3 contacts the top surface of the external mounting member 6. The crimping assembly 4 includes a pressing block 41, a gasket 43 and a fastener 42. The pressing block 41 is located above the external mounting member 6, and a crimping portion 411 is provided at one end of the pressing block 41, which is pressed against the upper surface of the bottom of the second mounting cavity 22.

[0032] Furthermore, a fixing portion 413 is provided at the other end of the pressure block 41 for fixing and installing the fastener 42; the fixing portion 413 and the gasket 43 are respectively arranged on the top surface and the bottom surface of the external mounting member 6, and the fixing portion 413 and the gasket 43 are fixedly installed on the external mounting member 6 by the fastener 42.

[0033] In this way, the anti-slip mounting assembly of this embodiment can clamp the bottom of the second mounting cavity 22 between the crimping portion 411 of the crimping assembly 4 and the support plate 3 through the cooperation between the support plate 3 and the crimping portion 411; and then through the mutual cooperation of the fixing portion 413, the gasket 43 and the fastener 42, the crimping assembly 4 can be fixedly installed on the external mounting part 6; this helps to prevent the photovoltaic frame 2 (especially the steel frame) from slipping out of the crimping assembly 4, and thus helps to avoid the risk of slipping of the photovoltaic assembly.

[0034] The crimping portion 411 is preferably a planar structure, which helps increase the crimping area of ​​the crimping portion 411 on the bottom of the second mounting cavity 22, ensuring that the crimping portion 411 is more stably pressed against the bottom of the second mounting cavity 22. The fixing portion 413 is also preferably a planar structure, which helps the fixing portion 413 to be fixed and installed more stably.

[0035] Furthermore, the plane where the fixing portion 413 lies is located above the plane where the crimping portion 411 lies. A first clamping portion 414 is also provided on the side of the fixing portion 413, away from the crimping portion 411, and gradually slopes downward, so that the free end of the first clamping portion 414 can contact and clamp onto the top surface of the external mounting member 6. Both ends of the gasket 43 slope upward from the inside to the outside, forming a second clamping portion 432 that contacts and clamps onto the bottom surface of the external mounting member 6. The cooperation between the first clamping portion 414 and the second clamping portion 432 facilitates a more stable fixing and installation of the crimping assembly 4 on the external mounting member 6.

[0036] Taking a threaded fastener as an example, the fastener 42 includes a bolt 421 and a nut 422 (eg Figure 1 The fixing portion 413 and the gasket 43 are respectively provided with a first mounting hole 4131 and a second mounting hole 431 (as shown). Figure 2). The lower end of the bolt 421 passes through the first mounting hole 4131 and the second mounting hole 431 in sequence, and is then threadedly connected to the nut 422 to fix the fixing portion 413 and the gasket 43 to the external mounting member 6.

[0037] Furthermore, to prevent the threaded bolt 421 and nut 422 from loosening, the fastener 42 also includes a washer 423 installed between the gasket 43 and the nut 422; the lower end of the bolt 421 passes through the washer 423 and is threadedly connected to the nut 422.

[0038] Furthermore, the bolts 421 are preferably inverted U-shaped bolts 421, with the front and rear surfaces of the external mounting member 6 both mounted within the openings of the inverted U-shaped bolts 421. Each inverted U-shaped bolt 421 is paired with two nuts 422 and two washers 423. Both the first mounting hole 4131 and the second mounting hole 431 are provided, two in number, to accommodate the threaded rods on either side of the opening of the inverted U-shaped bolt 421. Compared to conventional bolts 421, inverted U-shaped bolts 421 are easier to install and remove, and they improve the stability of the connection and resistance to external pressure.

[0039] The pressing block 41 is further provided with a transition portion 412 between the crimping portion 411 and the fixing portion 413. The side end portion of the support plate 3 extends to the bottom of the transition portion 412, and the side edge of the support plate 3 is provided with an upward extension portion 32. The free end of the bottom of the second mounting cavity 22 is provided with a bending portion 222. The bending portion 222 and the extension portion 32 respectively contact the two inner side surfaces of the transition portion 412, so that the bending portion 222, the support plate 3, the extension portion 32 and the transition portion 412 can together enclose a closed space 5 (such as a closed space 5) that resists external pressure (such as external wind pressure and snow pressure). Figure 1 This helps to avoid the risk of the C-side of the photovoltaic frame 2 being tilted and sliding out.

[0040] Furthermore, the transition portion 412 is tilted downward toward the fixing portion 413 , which can further reduce the volume of the enclosed space 5 and thereby improve the external pressure resistance of the enclosed space 5 .

[0041] Among them, see Figure 1-4 , a limiting structure 31 is provided on the support plate 3 (such as Figure 1 、 3 The limiting column shown in FIG), the pressing portion 411 and the second mounting cavity 22 are respectively provided with a pressing block limiting hole 4111 (as shown in FIG) for the limiting structure 31 to pass through. Figure 2 As shown) and the frame limiting hole 221 (as shown Figure 4 The limiting structure 31 can play a good limiting role on the pressing block 41 and the photovoltaic frame 2 (especially the steel frame), so as to prevent the pressing block 41 and the photovoltaic frame 2 from extending along the length direction of the photovoltaic frame 2 (corresponding to the longitudinal direction of the photovoltaic frame 2; and Figure 1Shown is the lateral movement of the photovoltaic frame 2.

[0042] In summary, the anti-slip mounting assembly of this embodiment, the pressing assembly 4 cooperates with the pressing block 41, the gasket 43 under the beam and the U-bolt 421, and then cooperates with the support plate 3 and its limiting structure 31. The support plate 3 is located on the lower surface of the bottom of the steel frame, and the pressing block 41 is located on the upper surface of the bottom of the steel frame. In this way, it can be safely and reliably ensured that the bottom of the steel frame can be firmly fixed between the pressing assembly 4 and the support plate 3 to achieve stable and reliable fixed installation of the steel frame, and further ensure the stability and reliability of the fixation of the photovoltaic module installed on the photovoltaic frame 2 (especially the steel frame) to prevent the steel frame and the photovoltaic module from slipping. Moreover, the anti-slip mounting assembly of this embodiment can be applied to a variety of steel frames with A surfaces of any shape, and has a wider range of applications.

[0043] In one example of this embodiment, the number of the crimping components 4 is at least two groups, and the parts of the two groups of crimping components 4 are respectively pressed on the upper surface of the bottom of the two photovoltaic frames 2, and the two ends of the support plate 3 are respectively arranged on the lower surface of the bottom of the two photovoltaic frames 2; the support plate 3 is correspondingly provided with at least two limiting structures 31 (such as Figure 1 、 3 As shown), each limiting structure 31 passes through and defines a corresponding set of crimping components 4 and a photovoltaic frame 2.
