Description

Technical Field

[0001] This utility model belongs to the field of solar module installation technology, specifically relating to a photovoltaic module frame that can be adapted to both flexible and rigid brackets. Background Technology

[0002] Traditional photovoltaic (PV) module frames are mostly designed for specific types of mounting systems, such as rigid or flexible supports. Installing PV modules on flexible supports requires the arrangement of steel cables between the modules according to design requirements, ensuring the cables have a reasonable route and appropriate length. Specialized cable connectors are used to connect the cables between the PV modules, ensuring a secure and reliable connection. Installing PV modules on rigid supports requires specialized PV panel clamps or clamps to fix the modules to the support. Due to the limitations of the frame structure, traditional PV modules cannot simultaneously meet the installation requirements of both types of mounting systems. This limits the flexibility and adaptability of PV modules, causing significant inconvenience during actual installation and construction, leading to increased installation costs and difficulty. With the continuous development of PV technology, the installation methods for PV modules are becoming increasingly diversified. Traditional PV module frames are mostly designed for rigid supports, such as ground-mounted power stations, distributed rooftops, and new energy vehicle sheds. However, with the development of photovoltaics, the number of available project sites is increasing, such as fishponds, lakes, valleys, and between buildings. In environments unsuitable for ground piling and rigid support, flexible support systems are being developed. Flexible support systems use suspended steel cables as supports, requiring additional installation fixtures for the photovoltaic module frames. Existing installation fixtures involve fixing the flexible support at four points before fixing the module. This installation method causes significant shaking of the photovoltaic module. Long-term shaking can easily cause cracks and falls at the frame positions of conventional modules that are fixed at four points. Furthermore, if conventional photovoltaic module frames adapted for rigid support installation are used for flexible support, there is not only a risk of module falling, but it also increases the cost of installation materials. Therefore, developing a photovoltaic module frame that can be adapted to both flexible and rigid support systems is particularly important, but there are currently no reports on related technologies. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a photovoltaic module frame that is easy to install, widely applicable, and compatible with both flexible and rigid brackets.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A photovoltaic module frame that is compatible with both flexible and rigid brackets includes two parallel first frame frames and two parallel second frame frames. The first and second frame frames are perpendicularly connected and together form a rectangular frame for fixing the photovoltaic panel. The bottom of the first frame frame has a mounting groove for a flexible support member to pass through. The mounting groove includes an outer side wall, an upper side wall, a lower side wall, and a slot. The slot faces the inside of the rectangular frame. The upper side wall is not higher than the bottom of the second frame frame. The lower side wall extends outward from the slot. A first bolt hole is formed on the lower side wall at the slot. Multiple first bolt holes are spaced apart along the length of the lower side wall. The slot is sealed by a first bolt and a first nut that mate with the first bolt hole.

[0006] The photovoltaic module frame that is compatible with both flexible and rigid brackets is described above. Preferably, the upper sidewall is flush with the bottom of the second frame.

[0007] The photovoltaic module frame that is compatible with both flexible and rigid brackets is described above. Preferably, the outer side wall is flush with the outer side of the first frame.

[0008] The photovoltaic module frame that is compatible with both flexible and rigid brackets is described above. Preferably, the first frame further includes a fixing groove and a reinforcing rib for fixing the photovoltaic panel, wherein the reinforcing rib is located between the fixing groove and the mounting groove.

[0009] The photovoltaic module frame that is compatible with both flexible and rigid brackets is described above. Preferably, the second frame includes a fixing groove for fixing the photovoltaic panel and a reinforcing rib, wherein the reinforcing rib is located between the fixing groove and the bottom of the second frame.

[0010] The photovoltaic module frame that is compatible with both flexible and rigid brackets is described above. Preferably, the length of the first frame is greater than the length of the second frame.

[0011] The photovoltaic module frame that is compatible with both flexible and rigid brackets is described above. Preferably, both the first frame and the second frame are aluminum alloy frames.

[0012] The photovoltaic module frame that is compatible with both flexible and rigid brackets, as described above, preferably also includes multiple sets of first bolts and first nuts, wherein the first nuts can be fixed at the slot.

[0013] The photovoltaic module frame that is compatible with both flexible and rigid brackets, as described above, preferably also includes a pressure block, a second bolt, and a second nut. The pressure block has a second bolt hole, and the second bolt passes through the second bolt hole and the bolt hole on the rigid bracket and then cooperates with the second nut to press and fix the first frame onto the rigid bracket.

[0014] The photovoltaic module frame that is compatible with both flexible and rigid brackets is described above. Preferably, the pressure block is a three-stage stepped bending structure. The three-stage stepped bending structure includes a first-stage step, a second-stage step, and a third-stage step connected sequentially from top to bottom. The lower surface of the first-stage step is used to fit against the upper surface of the first frame. The second bolt hole is located on the second-stage step. The lower surface of the third-stage step is used to fit against the rigid bracket.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] (1) To address the installation compatibility requirements with different types of brackets and photovoltaic modules, this utility model proposes a photovoltaic module frame that is compatible with both flexible and rigid brackets. The photovoltaic module frame has an installation groove at the bottom of the first frame, and multiple bolt holes are spaced along the length of the lower sidewall at the groove opening. The installation groove is used for the passage of flexible support components such as steel cables from the flexible bracket. Simultaneously, the upper sidewall of the installation groove is not higher than the bottom of the second frame, ensuring that the steel cable is not blocked by the second frame when it exits from both ends of the installation groove, thus adapting to the flexible connection requirements of the flexible bracket. The steel cable passes through the installation groove, and the bolt assembly locks the steel cable to ensure a tight and non-slip connection between the steel cable and the first frame, preventing loosening and detachment due to vibration, wind, or other factors. Because the flexible steel cable is in full contact with the internal groove of the first frame, even with shaking, the overall component is subjected to surface force, rather than the point force of traditional four-point installation, which is prone to uneven force distribution and component abnormalities. This process does not require additional fasteners, achieving flexible and stable installation of the photovoltaic module on the flexible bracket, and facilitating subsequent adjustments. The multiple bolt holes on the lower sidewall of the first frame can be used to fix the bolt assembly for sealing the slot and steel cable when adapted to a flexible support, and can also be used to fix the clamping block and bolt assembly when adapted to a rigid support. This utility model's photovoltaic module frame significantly improves installation convenience, increases installation efficiency, reduces labor costs, and enables efficient and convenient installation of photovoltaic modules on both flexible and rigid supports. It can be installed on rigid supports in conventional power plants using photovoltaic clamping blocks or bolts, and can also be internally penetrated on flexible steel cable supports in valleys, fishponds, etc., without needing to distinguish between the two environments. It uses bolt locking and does not require special installation clamping blocks or frame designs.

[0017] (2) The flexible design of the photovoltaic module frame of this utility model enables the photovoltaic system to be widely used under different terrain, climate conditions and installation requirements. It also makes the installation process simpler and faster. Whether it is the flexible adjustment of the flexible bracket or the stable support of the rigid bracket, the photovoltaic module can be fixedly installed through simple operation. The photovoltaic module frame of this utility model has strong compatibility, which expands the application range of photovoltaic modules, reduces the dependence on bracket type, and enhances the stability design, improving the installation stability of photovoltaic modules on different types of brackets, which is conducive to the long-term stable operation of photovoltaic systems.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 As shown, a photovoltaic module frame that can adapt to both flexible and rigid brackets includes two parallel first frame 1s and two parallel second frame 2s. The first frame 1s and second frame 2s are perpendicularly connected, and the first frame 1s and second frame 2s together form a rectangular frame for fixing the photovoltaic panel 01. The bottom of the first frame 1 is provided with a mounting groove 11 for a flexible support member 021 to pass through. Figure 2 As shown, the mounting groove 11 includes an outer side wall 111, an upper side wall 112, a lower side wall 113, and a groove 114. The groove 114 faces the interior of the rectangular frame. The upper side wall 112 is not higher than the bottom of the second frame 2. The lower side wall 113 extends outward from the groove 114. A first bolt hole 1131 is provided on the lower side wall 113 at the groove 114. Multiple first bolt holes 1131 are spaced apart along the length of the lower side wall 113, such as... Figure 3 As shown, the slot 114 is sealed by a first bolt 1132 and a first nut 1133 that mate with the first bolt hole 1131. The flexible support 021 is a steel cable.

[0029] Flexible support 02 refers to a photovoltaic installation system that can be flexibly adjusted according to various factors such as terrain, sunlight conditions, and seasonal changes. It is mainly made of steel wire rope or steel strand and other new flexible materials such as polymer materials and glass fiber reinforced materials. It has good elasticity and strength and is mainly used in valleys, water surfaces and other environments where it is not suitable for pile construction. Rigid support 03 refers to common photovoltaic installation facilities, mainly composed of new magnesium-aluminum steel and cement piles. It is mainly used in places such as Gobi Desert, grasslands and rooftops.

[0030] In this embodiment, the photovoltaic module frame is provided with a mounting groove 11 at the bottom of the first frame 1, and a plurality of bolt holes are provided at intervals along the length of the lower sidewall 113 at the groove opening 114. The mounting groove 11 is used for the steel cable of the flexible bracket 02 to pass through. At the same time, the upper sidewall 112 of the mounting groove 11 is not higher than the bottom of the second frame 2, so that the steel cable will not be blocked by the second frame 2 when it passes through the two ends of the mounting groove 11, so as to meet the flexible connection requirements of the flexible bracket 02. When adapted to the flexible bracket 02, simply insert the two steel cables of the flexible bracket 02 into the mounting groove 11 through the slot 114, so that they pass through the two parallel first frame frames 1. Then, pass the first bolt 1132 through the first bolt hole 1131 and engage with the first nut 1133. Since the first bolt hole 1131 is located at the slot 114, the bolt and nut fixed at the first bolt hole 1131 can lock the steel cable, ensuring that the steel cable does not slip with the frame and achieving a tight connection. This prevents loosening and falling off due to vibration, wind, or other factors. This process does not require additional fasteners and can achieve flexible and stable installation of the photovoltaic module on the flexible bracket 02. When adapted to the rigid bracket 03, a stable connection with the rigid bracket 03 is mainly achieved by engaging the first bolt hole 1131 of the lower side wall 113 of the first frame frame 1 with the bolt and nut. Alternatively, existing photovoltaic clamps can be used with bolts and nuts to achieve clamping installation from the outside of the photovoltaic frame. The dual-adaptive connection mechanism of the photovoltaic module frame in this embodiment can adapt to the different installation requirements of flexible bracket 02 and rigid bracket 03 without distinguishing between the two environments. It is convenient, efficient and widely applicable.

[0031] like Figure 4 , Figure 5 As shown, in this embodiment, the upper sidewall 112 is flush with the bottom of the second frame 2, which facilitates the assembly at the joint of the first frame 1 and the second frame 2. Since there is no height difference, the steel cable of the flexible bracket 02 will not be blocked by the joint of the second frame 2 when it passes through the two ends of the mounting groove 11, and the joint can be smoothly transitioned, which is beneficial to improving the stability of the photovoltaic module frame on the flexible bracket 02.

[0032] In this embodiment, the first frame 1 further includes a fixing groove 12 and a reinforcing rib 13 for fixing the photovoltaic panel 01, with the reinforcing rib 13 located between the fixing groove 12 and the mounting groove 11; the second frame 2 includes a fixing groove 12 and a reinforcing rib 13 for fixing the photovoltaic panel 01, with the reinforcing rib 13 located between the fixing groove 12 and the bottom of the second frame 2. During installation, the edge of the photovoltaic panel 01 is embedded into the fixing groove 12 for fixation, while the reinforcing rib 13 can improve the overall strength and rigidity of the frame, ensuring the installation stability of the photovoltaic module on different supports.

[0033] In this embodiment, the length of the first frame 1 is greater than the length of the second frame 2. Using the longer frame as the frame to be installed in conjunction with the flexible bracket 02 can further improve the overall support strength of the flexible bracket 02 for the photovoltaic module frame and the photovoltaic panel 01.

[0034] In this embodiment, both the first frame 1 and the second frame 2 are aluminum alloy frames. Choosing aluminum alloy as the frame material can simultaneously meet the requirements of photovoltaic module frames for strength and lightness.

[0035] In this embodiment, multiple sets of first bolts 1132 and first nuts 1133 are also included. The first nuts 1133 can be fixed at the slot 114. When adapting to the flexible bracket 02, the first bolts 1132 are installed upside down, and the first nuts 1133 are used to seal the slot 114. Selecting a first nut 1133 with a size slightly smaller than the width of the slot 114 is sufficient to seal and fix the steel cable, without the need for a special bolt assembly. When adapting to the rigid bracket 03, the first bolts 1132, the first nuts 1133, and the first bolt holes 1131 can be used to fix the photovoltaic module frame to the rigid bracket 03, without the need for a special bolt assembly or a special rigid bracket 03. Figure 6 As shown.

[0036] In this embodiment, the outer side wall 111 is flush with the outer side of the first frame 1, which facilitates the adaptation to existing photovoltaic blocks for clamping and installation, and has wide applicability.

[0037] like Figure 7As shown, this embodiment also includes a pressure block 14, a second bolt 141, and a second nut 142. The pressure block 14 is provided with a second bolt hole 143. The second bolt 141 passes through the second bolt hole 143 and the bolt hole on the rigid bracket 03 and then cooperates with the second nut 142 to press and fix the first frame 1 onto the rigid bracket 03. It can be applied to conventional pressure block installation of the prior art and has wide adaptability.

[0038] In this embodiment, the pressure block 14 has a three-stage stepped bending structure, which includes a first-stage step 144, a second-stage step 145, and a third-stage step 146 connected sequentially from top to bottom. The lower surface of the first-stage step 144 is used to fit against the upper surface of the first frame 1, the second bolt hole 143 is located on the second-stage step 145, and the lower surface of the third-stage step 146 is used to fit against the rigid bracket 03. In this embodiment, the locking force of the second bolt 141 and the second nut 142 is set in the middle between the upper surface of the first frame 1 and the upper surface of the rigid bracket 03 through the three-stage stepped bending structure, resulting in a better locking effect.

[0039] The conventional four-point installation of photovoltaic module frames and rigid brackets is as follows: Figure 8 As shown, point A is the installation point. The photovoltaic module frame and rigid bracket 03 are generally installed by bolt fixing or by side pressure block. Bolt fixing requires the extended surface of the frame to have bolt holes, while pressure block installation requires the outer side of the frame to be flat and have corresponding pressing points. The photovoltaic module frame in this embodiment meets all the above conditions, so it is applicable.

[0040] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
