Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment technology, and in particular to a fixing device for double-glass modules. Background Technology

[0002] Currently, most traditional double-glass photovoltaic modules (i.e., photovoltaic modules encapsulated with glass on both the front and back) use the frame structure of single-glass modules. This frame is typically made of 6063 or 6061 aluminum alloy through extrusion molding followed by anodizing. This structure usually has certain drawbacks, such as: (1) Insufficient stiffness and easy deformation: Double-glass modules do not require a backsheet, and their overall weight and rigidity distribution are different from those of single-glass modules, which places higher demands on the structural support of the frame. The cross-sectional moment of inertia of ordinary frames is relatively small. When the modules are handled, installed, and subjected to static and dynamic loads such as wind pressure and snow loads for a long time, especially for large-sized modules, they are prone to bending or torsional deformation. This deformation will be transmitted to the laminate, causing internal stress in the glass, increasing the risk of microcracks, and may also damage the sealing of the corner joints, causing problems such as water leakage and delamination.

[0003] (2) Heavy weight: In order to compensate for insufficient rigidity, the traditional approach is to simply increase the wall thickness or cross-sectional height of the frame. However, this directly leads to a significant increase in the weight of the frame and material costs, which runs counter to the trend of cost reduction and efficiency improvement in the photovoltaic industry. It also increases the load on the roof and the labor intensity of the installers.

[0004] (3) Unreliable corner connections: The four corners connected by corner brackets are weak points in the structure. When under stress, the stress is concentrated at the corner bracket screws, which can easily lead to the corner brackets breaking or the screws loosening. The long and short frames are perpendicular to each other at the corners, which makes it impossible to achieve continuous and parallel force transmission, resulting in poor overall structural stability.

[0005] (4) Inconvenient installation: Traditional corner connections require on-site assembly of corner brackets and tightening of screws, which is cumbersome and inefficient. In addition, the mounting edge of the frame is usually flat, and when it is used with the bracket clamp, it lacks effective anti-misalignment and anti-slip design, which poses a safety hazard.

[0025] The following reference Figures 1 to 6The present application describes a fixing device for a double-glass module according to embodiments thereof.

[0026] See Figures 1 to 6 As shown, an embodiment of this application provides a fixing device for a double-glass module. This fixing device includes multiple fixing frames, which are connected end-to-end to form a frame structure for fixing the double-glass module. Each fixing frame includes spaced-apart clamping cavities and reinforcing cavities. Each fixing frame also has claws for abutting against the double-glass module and clamping it to a certain extent. In this embodiment, the claws, clamping cavities, and reinforcing cavities are integrally formed with the fixing frames; or, the profile is processed to form the claws, clamping cavities, and reinforcing cavities, thereby ensuring the structural strength of each fixing frame. The fixing device also includes multiple connectors 3, with any two adjacent fixing frames connected by a connector 3.

[0027] Specifically, in this embodiment, there are four fixed frames, two of which are first fixed frames 1 and the other two are second fixed frames 2. Optionally, the length of the first fixed frame 1 is greater than the length of the second fixed frame 2. The two first fixed frames 1 are arranged in parallel and spaced apart, and the two second fixed frames 2 are arranged in parallel and spaced apart. Optionally, there are four connectors 3. The ends of the second fixed frames 2 are connected to the ends of the first fixed frames 1 through the connectors 3, so that the four fixed frames together form a quadrilateral frame structure.

[0028] Optionally, the length of the first fixed frame 1 is greater than the length of the second fixed frame 2. According to the design requirements, the profile is cut to obtain the long fixed frame and the end fixed frame, and the ends are precision milled to produce a 45° bevel, ensuring that the inner cavity opening is flat. If the design includes a mortise and tenon structure, it can be completed at the same time.

[0029] Further, the first fixed frame 1 includes: a first main body 101 and a first partition plate 102. The first main body 101 is in the shape of a long cylindrical strip. The first fixed frame 1 has a length, height and thickness according to its own usage state. The first partition plate 102 is disposed on the first main body 101 and is perpendicular to the first main body 101. The first partition plate 102 divides the internal space of the first main body 101 into a first clamping cavity 103 and a first reinforcing cavity 104 along the height direction of the first main body 101. The first clamping cavity 103 is used to install the double-glass assembly, and the first reinforcing cavity 104 is used to stably support the first clamping cavity 103. The cross-section of the first reinforcing cavity 104 along the thickness direction of the first main body 101 can be a closed rectangle, trapezoid or other shape. The first reinforcing cavity 104 can stably support the first clamping cavity 103 and the double-glass assembly installed in the first clamping cavity 103.

[0030] Optionally, at least one reinforcing plate is provided at intervals along the length of the first reinforcing cavity 104, so that, except for the case where the first reinforcing cavity 104 is a whole cavity, the first reinforcing cavity 104 can also be divided into multiple hollow cavities with closed cross-sections by the reinforcing plates. These hollow cavities can provide the maximum moment of inertia of the cross section with the least amount of material. According to the test, compared with the solid wall structure, the hollow cavity design can reduce the weight by 25%-35% while ensuring the same stiffness.

[0031] In addition to the two end ports shared with the first main body 101 along its length, the first clamping cavity 103 is also provided with a first insertion interface, through which the edge of the double glass assembly is inserted into the first clamping cavity 103.

[0032] The first clamping cavity 103 is provided with a first claw 105 on the side facing the first partition plate 102. The first claw 105 is generally elongated. One side of the first claw 105 is connected to the first main body 101, and the other side of the first claw 105 is provided with a hook that bends toward the first partition plate 102. The first claw 105 and the first partition plate 102 define a cavity that can clamp the edge of the double-glass module. After the double-glass module is inserted into the first clamping cavity 103 through the first insertion interface, the upper wall surface of the double-glass module can contact the first claw 105, the lower wall surface of the double-glass module can contact the first partition plate 102, and the side wall surface of the double-glass module can contact the inner surface of the side wall of the first clamping cavity 103 located between the first claw 105 and the first partition plate 102.

[0033] Optionally, the surfaces of the double-glass assembly that can contact the first clamping cavity 103 are coated with sealant. Optionally, the sealant is a silicone-based or butyl hot melt sealant.

[0034] The first claw 105 is provided with a first sealing groove 106 on the wall facing the first partition plate 102. The length of the first sealing groove 106 extends along the length direction of the first main body 101. The first sealing groove 106 is filled with a certain amount of sealant. It should be noted that the sealant in the first sealing groove 106 can be filled by pre-filling or post-filling to ensure the sealing of the double glass assembly installation.

[0035] Furthermore, the first fixed frame 1 also includes a first reinforcing member 107, specifically a reinforcing rib. The number of first reinforcing members 107 is at least two. All the first reinforcing members 107 are spaced apart along the width direction of the first partition plate 102 on the side surface of the first partition plate 102 facing the first reinforcing cavity 104, and on the side surface of the first reinforcing cavity 104 facing the first partition plate 102 (that is, the inner wall surface of the bottom wall of the first reinforcing cavity 104). The first reinforcing members 107 protrude relative to the plate surface of the first partition plate 102 and the bottom wall surface of the first reinforcing cavity 104. Each first reinforcing member 107 divides the internal space of the first reinforcing cavity 104 into several small chambers, which greatly improves the bending stiffness of the first fixed frame 1 in the vertical direction, that is, in the height direction of the first fixed frame 1. Optionally, the thickness of the first reinforcing member 107 is 1.5mm. According to tests, under the same material and the same material usage, the vertical bending stiffness of the frame can be increased by about 40%.

[0036] Furthermore, the first fixed frame 1 also includes a fixing part 108, which is plate-shaped and extends along the length direction of the first main body 101. The fixing part 108 is disposed on the side of the first main body 101 near the other first fixed frame 1. Optionally, the fixing part 108 is disposed at the bottom of the first main body 101 and is coplanar with the bottom wall surface of the first reinforcing cavity 104.

[0037] The fixing part 108 is provided with multiple connecting holes, which are spaced apart along the length of the fixing part 108, so as to use bolts or other fasteners to fix the fixing part 108 together with the first fixing frame 1 to the designated position.

[0038] Furthermore, the structure of the second fixed frame 2 is the same as that of the first fixed frame 1. The second fixed frame 2 includes a second main body 201 and a second partition plate 202. The second partition plate 202 divides the second main body 201 into a second clamping cavity 203 and a second reinforcing cavity 204. The second fixed frame 2 also includes a second claw 205 and a second reinforcing member 207. The structure of the second claw 205 is the same as that of the first claw 105, and it is also provided with a second sealing groove 206. The number and position of the second reinforcing members 207 are the same as those described above. Those skilled in the art will fully understand this, and the same and similar contents will not be described in detail here.

[0039] The second fixed frame 2 may be equipped with a fixing part 108 depending on the installation conditions and requirements.

[0040] It should be noted that both the first fixed frame 1 and the second fixed frame 2 are integrally structured using profiles processed through extrusion and other processes, ensuring overall structural strength. Optionally, in this embodiment, the first fixed frame 1 and the second fixed frame 2 are both made of high-strength aluminum alloys commonly used in the prior art, such as aluminum alloys with grades 7005 or 7075, and are subjected to T5 or T6 heat treatment to obtain strength superior to ordinary aluminum alloys. This significantly reduces the risk of deformation of the fixing device used for double-glass modules, thereby improving the installation stability and support stability of the double-glass modules. The extruded profiles are subjected to online quenching and artificial aging (T5 state) to achieve the required mechanical properties. Tests show that the tensile strength of 7005-T5 can reach over 345 MPa, effectively resisting wind pressure greater than 5400 Pa and snow load greater than 5000 Pa, suitable for various harsh environments, and maximizing the protection of the glass from microcracks.

[0041] The fixing device for double-glass modules provided in this application achieves a lightweight effect through the hollow cavity structure and the use of high-strength aluminum alloy profiles. While achieving the same or even higher stiffness, the frame weight is reduced by 20%-30% compared to traditional solutions. Taking a 182mm double-glass module as an example, the total frame weight can be reduced from approximately 2.8kg to around 2.0kg.

[0042] Optionally, both ends of the first fixed frame 1 and the ends of the second fixed frame 2 are provided with chamfered edges to facilitate splicing into a frame structure.

[0043] Furthermore, the first fixed frame 1 also includes a mounting guide rail 5 and a fastening connector. The first main body 101 is provided with a mounting port 4. The mounting part is specifically located at the bottom of the first reinforcing cavity 104. The inner and outer spaces of the first reinforcing cavity 104 are connected at the mounting port 4. The mounting guide rail 5 is located inside the first reinforcing cavity 104 and at the edge of the mounting port 4. The fastening connector can be a T-bolt. When installing the fixing device for the double-glass module, the mounting guide rail 5 and the mounting port 4 can be used to pass through the T-bolt. Simply slide the T-bolt into the designated position in the groove defined by the mounting guide rail 5 and tighten the T-bolt. There is no need to drill holes on the frame on-site, avoiding strength weakening and installation errors caused by improper drilling. The mounting guide rail 5 and the mounting port 4 are T-shaped or approximately T-shaped, so that the installation process does not require on-site drilling, positioning is fast and accurate, and installation efficiency is improved by more than 50%. The use of the parallel connector 3 also makes the frame assembly simpler and more secure.

[0044] The second fixed frame 2 can be determined based on the installation conditions and requirements, and whether or not it is necessary to set up the installation guide rail 5 and the installation port 4.

[0045] Further, the connector 3 is specifically a connecting corner bracket. The connector 3 includes a first connecting portion 301 and a second connecting portion 302 distributed at an angle. Optionally, the first connecting portion 301 and the second connecting portion 302 are arranged perpendicularly. The first connecting portion 301 is used to connect with the first fixed frame 1, and the second connecting portion 302 is used to connect with the second fixed frame 2. In this embodiment, the first fixed frame 1 and the second fixed frame 2 are connected by connecting corner brackets. The traditional connection method is to use bolts. This connection method involves shear force through the bolts, rather than the peeling force that would cause the corner bracket to break. Therefore, the connection strength is far inferior to the fixing device for double-glass modules provided in this application. According to the test, the corner tensile strength of the fixing device for double-glass modules provided in this application is at least 300% higher than that of the traditional connection method, and the shear strength is at least 250% higher, which greatly eliminates the risk of corner cracking.

[0046] The first connecting part 301 and the second connecting part 302 face each other and are adjacent to each other. The first fitting part 303 specifically includes a plurality of teeth arranged sequentially along the length of the first connecting part 301 and the length of the second connecting part 302.

[0047] The first connecting part 301 can be inserted into the first reinforcing cavity 104, and the second connecting part 302 can be inserted into the second reinforcing cavity 204. Optionally, the first reinforcing cavity 104 and the wall surface facing the first fitting part 303 on the first connecting part 301 are provided with a second fitting part, and the wall surface facing the second reinforcing cavity 204 and the wall surface facing the second fitting part on the second connecting part 302 are provided with a third fitting part. Both the second fitting part and the third fitting part include teeth that can be adapted to the first fitting part 303 to ensure the stability of the connector 3 between the first fixed frame 1 and the second fixed frame 2, thereby ensuring the connection strength of the connector 3 in connecting the first fixed frame 1 and the second fixed frame 2.

[0048] Optionally, cylindrical nesting members are provided at both ends of the first reinforcing cavity 104 and both ends of the second reinforcing cavity 204. The inner wall surface of the nesting member is provided with a second fitting part / third fitting part for fitting with the first fitting part 303. This arrangement can ensure the connection strength between the connector 3 and the first fixed frame 1 and the second fixed frame 2, and does not require structural changes to the first reinforcing cavity 104 and the second reinforcing cavity 204, thus avoiding affecting the structural strength of the first fixed frame 1 and the second fixed frame 2. It can also avoid repeated installation causing the second fitting part and the third fitting part to slip.

[0049] Optionally, a dense oxide film is formed on the surface of both the first fixed frame 1 and the second fixed frame 2. Preferably, the thickness of the oxide film is 15-20μm, which improves corrosion resistance and makes the fixing device used for double glass modules have strong fatigue resistance, able to withstand long-term wind vibration and thermal expansion and contraction, and its service life matches that of the module itself, requiring no maintenance.

[0050] Optionally, after connecting the first fixed frame 1 and the second fixed frame 2 using connector 3, through bolts are used to connect the first fixed frame 1 to the first connecting part 301 and the second fixed frame 2 to the second connecting part 302. This forms the final form of the fixing device for double-glass modules, ensuring the structural strength of the fixing device. Simultaneously, the robust connection provides a rigid foundation for edge sealing, ensuring the sealing reliability of the module throughout its entire lifespan and effectively preventing phenomena such as PID (potential-induced degradation).

[0051] In summary, the fixing device for double-glass modules provided in this application uses connector 3 to connect the various fixing frames, enabling parallel force flow transmission between the fixing frames at the top corners, rather than the traditional end-to-end contact. This also disperses stress, reducing the risk of top corner cracking. Furthermore, the structural improvements to the fixing frames result in an order-of-magnitude increase in the moment of inertia and flexural section modulus of the fixing frames, significantly improving the stiffness and deformation resistance of the fixing device for double-glass modules. Therefore, the fixing device for double-glass modules provided in this application significantly improves the support strength and installation stability of double-glass modules through optimization of both the connection structure and the support structure of the double-glass modules.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
