Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics, and particularly relates to the installation technology of photovoltaic modules.

Background Art

[0002] With the structural characteristics of "large span, high clearance, and long row spacing", the flexible photovoltaic support effectively solves the adaptability and economy problems of the support in certain scenarios, and the application of this technology has attracted more and more attention in the industry. However, the flexible support is easily affected by wind, and wind-induced vibrations are likely to occur between the modules, resulting in module hidden cracks and reduced power generation efficiency of the modules.

[0003] Chinese Patent Publication No. CN 219576908 U discloses a flexible support and its connection structure. The connection structure of the flexible support is used for connecting the flexible support and the photovoltaic module. The connection structure includes a cable connection component and a damping connection component. The cable connection component is used to connect with the flexible cable of the flexible support, and the damping connection component is used to connect with the frame of the photovoltaic module. The cable connection component is connected to the photovoltaic module through the damping connection component. The cable connection component includes a U-shaped connector, a first connecting rod member, and a first fastener. The first connecting rod member passes through the opposite sides of the U-shaped connector and is used to clamp the flexible cable with the bottom of the U-shaped connector. The two ends of the first connecting rod member are respectively fastened with the first fastener, and the first fastener abuts against the opposite sides of the U-shaped connector. The two ends of the U-shaped connector are respectively connected to the damping connection component. The damping connection component includes a connecting part and two springs. The connecting part is connected to the frame of the photovoltaic module. The two springs are respectively arranged in the frame of the photovoltaic module. One ends of the two springs are both connected to the connecting part, and the other ends are respectively connected to the two ends of the U-shaped connector in one-to-one correspondence. Although the above structure can solve the problem of wind-induced vibrations between the modules, it has a complex structure, cumbersome installation, and high cost.

Content of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a flexible shock-absorbing photovoltaic system, which can not only avoid wind-induced vibrations between the modules, resulting in module hidden cracks, but also has the advantages of low cost and convenient installation.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: A flexible shock-absorbing photovoltaic system includes photovoltaic modules arranged side by side and a flexible shock-absorbing component connecting two adjacent photovoltaic modules. The flexible shock-absorbing component includes a flexible restraint inner clamp connected to the frame of the photovoltaic module and a flexible restraint outer clamp arranged between the frames of two adjacent photovoltaic modules. The flexible restraint inner clamp and the flexible restraint outer clamp are connected together, and all the photovoltaic modules are flexibly connected into a whole.

[0006] Preferably, the flexible constraint inner clip includes a clamping portion clamped to the C side of the frame and an inner constraint edge extending upward from the upper side edge of the clamping portion and cooperating with the inner side of the B side of the frame.

[0007] Preferably, the flexible constraint outer clip is of a U-shaped structure, and outer constraint edges corresponding to the two sides of the U shape are respectively provided for cooperating with the outer sides of the B sides of the frame of the two photovoltaic modules on both sides.

[0008] Preferably, the flexible constraint inner clip further includes an outer extension edge horizontally extending from the lower side edge of the clamping portion and overlapping and fixing with the bottom edge of the U-shaped structure.

[0009] Preferably, the bottom edge of the U-shaped structure and the outer extension edge are fixed by bolts.

[0010] Preferably, an arc transition portion is provided between the upper side edge of the clamping portion and the inner constraint edge.

[0011] Preferably, the upper side edge and the lower side edge of the clamping portion are fixed to the C side of the frame by fasteners.

[0012] Preferably, the fastener is a bolt, and a gasket is provided on the bolt.

[0013] Preferably, both the flexible constraint inner clip and the flexible constraint outer clip are sheet metal parts.

[0014] Preferably, the flexible constraint inner clip and the flexible constraint outer clip are made of stainless steel or aluminum alloy.

[0015] The utility model adopts the above technical solutions and has the following beneficial effects:

[0016] 1. The flexible constraint inner clip flexibly constrains the frame of the single photovoltaic module. Since a flexible constraint outer clip connected to the flexible constraint inner clip is provided between the frames of two adjacent photovoltaic modules, the flexible constraint outer clip can not only flexibly constrain the relative positions of two adjacent photovoltaic modules, but also connect the frames of two adjacent photovoltaic modules together after the combination of the flexible constraint inner clip and the flexible constraint outer clip, and finally can connect all the photovoltaic modules in the entire photovoltaic system into a whole to reduce the vibration frequency, thereby reducing the possibility of component hidden cracks.

[0017] The flexible constraint inner clip is connected to the frame of the photovoltaic module by a common clamping structure, and the flexible constraint inner clip and the flexible constraint outer clip can be connected together by a conventional connection structure, such as a fastener, so it is convenient for installation, and because the component structure is simple and the number of components is small, it has a low cost and is convenient for large-scale application.

[0018] 2. The clamping part is clamped on the C side of the frame, which can ensure reliable fixation with the frame. Therefore, the flexible restraint inner clamp and the photovoltaic module form an integral whole. Since the bottom edge and the outer extension edge of the U-shaped structure are overlapped and fixed, the flexible restraint outer clamp and the flexible restraint inner clamp form an integral whole. And because the inner restraint edge and the outer restraint edge cooperate to clamp the B side of the frame, the flexible shock-absorbing component and the photovoltaic module form an integral whole. Moreover, both the flexible restraint outer clamp and the flexible restraint inner clamp can be flexibly deformed, and the cooperation between the inner restraint edge and the restraint edge avoids the horizontal sliding of the module and provides shock-absorbing protection, ensuring the exertion of the flexible shock-absorbing function.

[0019] 3. Bolts are used to fix the clamping part to the C side of the frame, and the flexible restraint inner clamp and the flexible restraint outer clamp are connected, so as to ensure reliable fixation of the clamping part to the C side of the frame and reliable connection between the flexible restraint inner clamp and the flexible restraint outer clamp, so as to ensure that all photovoltaic modules are flexibly connected into an integral whole.

[0020] 4. Two groups of flexible shock-absorbing components corresponding to the connection of the opposite two frames of the photovoltaic module are symmetrically arranged on both sides of the center line of the photovoltaic module. At the same time, the flexible shock-absorbing components are arranged at multiple positions on the frame of the photovoltaic module, which can ensure that the photovoltaic module is evenly supported and restrained, making the whole system more stable when affected by wind force.

[0021] 5. The restraint inner clamp and the restraint outer clamp are sheet metal parts. The sheet metal parts have the advantages of light weight, high strength, low cost, and good mass production performance. Moreover, due to having a certain elasticity and flexibility, they are perfectly adapted to the photovoltaic flexible bracket.

[0022] 6. The restraint inner clamp and the restraint outer clamp are made of stainless steel or aluminum alloy, which not only prevents rust and extends the service life, but also has the advantage of low mass production cost.

[0023] These features and advantages of the present utility model will be detailedly disclosed in the following specific embodiments and drawings.

[0030] The technical solutions of the embodiments of the present utility model will be explained and described below with reference to the drawings of the embodiments of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0031] Those skilled in the art can understand that, without conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0032] The terms used in the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. For example, the terms such as "upper", "lower", "longitudinal", "transverse" and the like indicating the orientation or position relationship are only based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present utility model.

[0033] In the present utility model, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features therebetween. Moreover, the first feature being "above", "over" and "on" the second feature includes that the first feature is directly above and obliquely above the second feature, or only means that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "under" and "beneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or only means that the horizontal height of the first feature is lower than that of the second feature.

[0034] In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0035] Referring to the prior art, for a conventional flexible shock-absorbing photovoltaic system, several photovoltaic modules are distributed in a rectangular array and installed on a flexible photovoltaic support. The photovoltaic modules are provided with frames. Since the photovoltaic array is installed on the flexible photovoltaic support, the flexible photovoltaic support is easily affected by wind, and wind-induced vibrations are likely to occur between the modules, resulting in hidden cracks in the modules and a reduction in the power generation efficiency of the modules.

[0036] To address this problem, referring to Figures 1 to 4 as shown, this embodiment provides a flexible shock-absorbing photovoltaic system, including photovoltaic modules 1 arranged side by side and flexible shock-absorbing components 2 connecting adjacent two photovoltaic modules. The flexible shock-absorbing component 2 includes a flexible restraint inner clamp 21 connected to the frame of the photovoltaic module and a flexible restraint outer clamp 22 disposed between the frames of adjacent two photovoltaic modules. The flexible restraint inner clamp 21 and the flexible restraint outer clamp 22 are connected together, and all the photovoltaic modules 1 are flexibly connected into a whole.

[0037] Among them, the flexible restraint inner clamp flexibly restrains the frame of a single photovoltaic module. Since there is a flexible restraint outer clamp connected to the flexible restraint inner clamp between the frames of adjacent two photovoltaic modules, the flexible restraint outer clamp can not only flexibly restrain the relative positions of adjacent two photovoltaic modules, but also connect the frames of adjacent two photovoltaic modules together after the combination of the flexible restraint inner clamp and the flexible restraint outer clamp. Finally, all the photovoltaic modules in the entire photovoltaic system can be connected into a whole to reduce the vibration frequency, thereby reducing the possibility of hidden cracks in the modules.

[0038] The flexible restraint inner clamp is connected to the frame of the photovoltaic module by a common clamping structure. The flexible restraint inner clamp and the flexible restraint outer clamp can be connected together by a conventional connection structure, such as fasteners. Therefore, it is convenient for installation, and because the component structure is simple and the number of components is small, it has a low cost and is convenient for large-scale application.

[0039] It can be understood that the flexible shock-absorbing components 2 are arranged at multiple positions on the four peripheral frames of the photovoltaic module. Taking the photovoltaic module in the middle as an example, there are adjacent photovoltaic modules 1 on all four sides, and each frame is connected to 2 or 3 flexible shock-absorbing components 2. Moreover, the two groups of flexible shock-absorbing components 2 connected to the corresponding two frames 100 of the photovoltaic module 1 are symmetrically arranged on both sides of the center line of the photovoltaic module. Here, the center line refers to the longitudinal center line and the transverse center line. Taking the symmetry on both sides of the transverse center line as an example, the multiple flexible shock-absorbing components connected to the frames on the transverse two sides correspond in the longitudinal position. In this way, it can be ensured that the photovoltaic module is uniformly supported and restrained, making the entire system more stable when subjected to wind force.

[0040] Specifically, as Figure 3As shown, the flexible constraint inner clamp 21 includes a clamping portion 211 clamped to the C side 102 of the frame and an inner constraint edge 212 extending upward from the upper side edge of the clamping portion and cooperating with the inner side of the B side 101 of the frame. As Figure 4 As shown, the flexible constraint outer clamp 22 is a U-shaped structure, and outer constraint edges 222 corresponding to the two sides of the U shape are provided for cooperating with the outer sides of the B sides of the two photovoltaic module frames. In addition, the flexible constraint inner clamp 21 further includes an outer extension edge 213 horizontally extending from the lower side of the clamping portion and overlapping and fixing with the bottom edge 221 of the U-shaped structure, which is convenient for connecting with the flexible constraint inner clamp. An arc transition portion 214 is provided between the upper side of the clamping portion and the inner constraint edge. The clamping portion is clamped to the C side of the frame, which can ensure reliable fixation with the frame. Therefore, the flexible constraint inner clamp and the photovoltaic module form an integral whole. Since the bottom edge of the U-shaped structure overlaps and fixes with the outer extension edge, the flexible constraint outer clamp and the flexible constraint inner clamp form an integral whole. And because the inner constraint edge and the outer constraint edge cooperate to clamp the B side of the frame, the flexible shock absorption assembly and the photovoltaic module form an integral whole. Moreover, both the flexible constraint outer clamp and the flexible constraint inner clamp can be flexibly deformed, and the cooperation between the inner constraint edge and the constraint edge avoids the horizontal sliding of the assembly and provides shock absorption protection, ensuring the exertion of the flexible shock absorption function.

[0041] Among them, bolts 23 are used to fix the upper side and the lower side of the clamping portion 211 to the C side of the frame, and connection holes for connecting with the bolts are preset on the C side of the frame. Bolts 23 are used to fix the bottom edge 221 of the U-shaped structure and the outer extension edge 213, and connection holes for connecting with the bolts are preset on the bottom edge 221 of the U-shaped structure and the outer extension edge 213. The bolts can be hexagon socket head cap screws, and gaskets are provided for the bolts. Thereby ensuring reliable fixation of the clamping portion to the C side of the frame and reliable connection between the flexible constraint inner clamp and the flexible constraint outer clamp, so as to ensure that all photovoltaic modules are flexibly connected into an integral whole.

[0042] Specifically, both the flexible constraint inner clamp 21 and the flexible constraint outer clamp 22 are sheet metal parts. Sheet metal parts have the advantages of light weight, high strength, low cost, and good mass production performance. Moreover, due to having a certain elasticity and flexibility, they are perfectly adapted to the photovoltaic flexible bracket. The flexible constraint inner clamp and the flexible constraint outer clamp are made of stainless steel or aluminum alloy. It not only prevents rust and extends the service life, but also has the advantage of low mass production cost.

[0043] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Those skilled in the art should understand that the utility model includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the utility model will be included in the scope of the claims.
