Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment components technology, specifically to a photovoltaic module mounting block and a photovoltaic system. Background Technology

[0002] Photovoltaic module mounting blocks are an important accessory used in the installation of photovoltaic modules. They are primarily used to secure the photovoltaic modules to the photovoltaic support structure, providing stability and support. By firmly pressing the photovoltaic modules onto the support, the blocks prevent displacement, shaking, or even detachment due to external forces such as wind and vibration, ensuring the stability and safety of the photovoltaic module installation.

[0003] Currently, most photovoltaic (PV) module mounting blocks on the market have a U-shaped structure. While these blocks effectively position the PV modules, their constraint only applies vertically. This makes them prone to deformation under stress, leading to unstable installation. Under positive wind pressure, the PV module panel will sag downwards, and the module frame will rotate. The mounting block offers little resistance to this rotation. Simultaneously, the rotating frame exerts force on the side (top or bottom) of the mounting block, and conventional blocks lack special designs to resist this force. Under negative wind pressure, the PV module panel will bulge upwards, and the module frame will rotate. Again, the mounting block offers little resistance to this rotation. The rotating frame exerts force on the side (top or bottom) of the mounting block, and conventional blocks lack special designs to resist this force. Utility Model Content

[0004] In view of this, the present invention provides a photovoltaic module mounting block and a photovoltaic system to solve the problem that the current photovoltaic module mounting blocks are prone to deformation under stress, resulting in unstable installation of photovoltaic modules.

[0005] In a first aspect, this utility model provides a photovoltaic module mounting block, comprising:

[0006] The pressing block body is a hollow frame structure.

[0007] A force-bearing structure is disposed inside the pressing block body. When the pressing block body is subjected to force, the force-bearing structure is adapted to provide resistance to the pressing block body to prevent the pressing block body from deforming.

[0008] The beneficial effects of the aforementioned photovoltaic module mounting block are as follows: While maintaining the original U-shaped structure, the block incorporates a special design to constrain the rotation of the photovoltaic module. An internal force-bearing structure is incorporated within the block. When the photovoltaic module rotates due to wind force, this structure effectively resists the force generated by the module's rotation, preventing excessive rotation and thus maintaining the module's stability.

[0009] More specifically, the compact body is a hollow frame structure. With the internal force-bearing structure, when the compact body is subjected to positive or negative wind pressure, the force-bearing structure can provide additional resistance to the compact body, effectively preventing deformation of the compact body due to excessive local stress. Through the support of the force-bearing structure, the rotation tendency of the photovoltaic module can be limited, thereby improving the stability of the compact body under high wind load scenarios and improving the installation stability of the photovoltaic module.

[0010] In one optional embodiment, the force-bearing structure is arranged horizontally inside the pressure block body, which can improve the vertical shear resistance and resist the horizontal force generated by the rotation of the photovoltaic module on the horizontal direction of the pressure block body, thereby ensuring that the photovoltaic module does not deflect under the action of external wind pressure.

[0011] In one alternative implementation, the load-bearing structure is a reinforcing plate.

[0012] In one optional embodiment, the pressure block body includes a connecting plate, a first side plate, a second side plate, and a pressure plate;

[0013] The connecting plate is adapted to connect with the base layer. The first side plate and the second side plate are disposed on both sides of the connecting plate. The first side plate, the connecting plate and the second side plate surround to form the frame structure. One end of the frame structure is open.

[0014] The pressure plate may be provided in one or two ways; when there is one pressure plate, the pressure plate extends outward and is provided on the side of the first side plate or the second side plate; when there are two pressure plates, the two pressure plates extend outward and are provided on the side of the first side plate and the second side plate, respectively.

[0015] In one alternative embodiment, the load-bearing structure is disposed between the first side plate and the second side plate.

[0016] The beneficial effects of the above technical solution are as follows: the load-bearing structure forms a lateral support between the two side plates, which can directly offset the lateral force on the side plates, avoid deformation of the side plates, and thus maintain the effective constraint of the pressure block on the photovoltaic module.

[0017] In one optional embodiment, the frame structure formed by the first side plate, the connecting plate, and the second side plate is a U-shaped structure.

[0018] In one optional embodiment, an anti-slip structure is provided on the wall surface where the pressure plate contacts the photovoltaic module frame, and / or on the wall surface where the first side plate contacts the photovoltaic module frame, and / or on the wall surface where the connecting plate contacts the base layer, and / or on the wall surface where the second side plate contacts the photovoltaic module frame.

[0019] The beneficial effects of the above technical solution are as follows: the anti-slip structure can increase the friction between the pressure block body and the photovoltaic module frame, effectively preventing the sliding between the photovoltaic module frame and the pressure block body, thereby improving the installation stability of the photovoltaic module.

[0020] In addition, an anti-slip structure can be installed on the wall surface where the connecting plate contacts the base layer, which can increase the friction between the pressing block body and the base layer, prevent the pressing block body from shifting, and make the connection between the connecting plate and the base layer more stable.

[0021] In one alternative embodiment, the anti-slip structure includes a plurality of spaced-apart serrations or reinforcing ribs.

[0022] In one alternative embodiment, the opening of the frame structure is covered with a snap-on cover.

[0023] Secondly, this utility model provides a photovoltaic system, comprising:

[0024] Multiple photovoltaic module mounting blocks, wherein the photovoltaic module mounting blocks are positioned on the base layer;

[0025] Multiple photovoltaic modules, each photovoltaic module including a photovoltaic module panel and a photovoltaic module frame, wherein the two ends of the photovoltaic module panel are respectively positioned on two photovoltaic module frames, and the photovoltaic module frames are connected to the base layer and limited by photovoltaic module mounting blocks.

[0026] The photovoltaic system of the second aspect of this utility model includes a photovoltaic module mounting block, which has the same effect as the photovoltaic module mounting block, and will not be described in detail here. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0040] Combination Figure 1 and Figure 2 As shown, the photovoltaic module mounting blocks currently on the market are U-shaped. While they can effectively position the photovoltaic modules, the constraint provided by the blocks is only in the vertical direction. Combined with... Figure 3 As shown, under positive wind pressure, the photovoltaic module panel will indent downwards, and the module frame will rotate. The pressure block has virtually no constraint on this rotational tendency of the frame. Simultaneously, the frame rotation exerts a force on the side (top or bottom) of the pressure block, and conventional pressure blocks lack special designs to resist this force. Combined with... Figure 4As shown, under negative wind pressure, the photovoltaic module panel will bulge upwards, and the module frame will rotate. In this state, the pressure block has virtually no constraint on the rotation tendency of the frame. At the same time, the frame rotates and exerts a force on the side (top or bottom) of the pressure block. Conventional pressure blocks do not have a special design to resist this force.

[0041] To address the aforementioned problems, this invention proposes a novel photovoltaic module mounting block. While maintaining the original U-shaped structure, this block incorporates a special design to constrain the rotation of the photovoltaic module. An internal force-bearing structure is incorporated into the block. When the photovoltaic module rotates due to wind force, this structure effectively resists the forces generated by the module's rotation, preventing excessive rotation and thus maintaining the module's stability.

[0042] According to an embodiment of the present invention, in a first aspect, a photovoltaic module mounting clamp is provided, combined with... Figures 5 to 8 As shown, it includes a pressing block body 1 and a force-bearing structure 2. The pressing block body 1 is a hollow frame structure. The force-bearing structure 2 is located inside the pressing block body 1. When the pressing block body 1 is subjected to force, the force-bearing structure 2 is adapted to provide resistance to the pressing block body 1 to prevent deformation of the pressing block body 1.

[0043] The aforementioned photovoltaic module mounting block has a hollow frame structure 1. In conjunction with the internal force-bearing structure 2, when the mounting block 1 is subjected to positive or negative wind pressure, such as when the photovoltaic module rotates and the side of the mounting block is subjected to force, the force-bearing structure 2 can provide additional resistance to the mounting block 1, effectively preventing the mounting block from deforming due to excessive local force. Through the support of the force-bearing structure 2, the rotation trend of the photovoltaic module can be limited, thereby improving the stability of the mounting block under high wind load scenarios and enhancing the installation stability of the photovoltaic module.

[0044] In some embodiments, the force-bearing structure 2 is arranged horizontally inside the pressure block body 1, which can improve the vertical shear resistance and resist the horizontal force generated by the rotation of the photovoltaic module on the horizontal direction of the pressure block body 1, thereby ensuring that the photovoltaic module does not deflect under the action of external wind pressure.

[0045] More specifically, the load-bearing structure 2 is a reinforcing plate, which can be integrally formed with the pressing block body 1 or separately connected to the pressing block body 1.

[0046] In some embodiments, the pressure block body 1 includes a connecting plate 11, a first side plate 12, a second side plate 13, and a pressure plate 14.

[0047] The connecting plate 11 is adapted to be connected to the base layer 6. The connecting plate 11 is provided with through holes, and bolts pass through the through holes on the connecting plate 11 to connect the connecting plate 11 to the base layer 6.

[0048] The first side plate 12 and the second side plate 13 are arranged parallel or non-parallel on both sides of the connecting plate 11. The first side plate 12, the connecting plate 11 and the second side plate 13 form a frame structure, with one end of the frame structure open. More specifically, the frame structure formed by the first side plate 12, the connecting plate 11 and the second side plate 13 is a U-shaped structure.

[0049] There may be one or two pressure plates 14. When there is one pressure plate 14, the pressure plate 14 extends outward and is disposed on the side of the first side plate 12 or the second side plate 13; when there are two pressure plates 14, the two pressure plates 14 extend outward and are disposed on the side of the first side plate 12 and the second side plate 13 respectively.

[0050] In some embodiments, the force-bearing structure 2 is disposed between the first side plate 12 and the second side plate 13. The force-bearing structure 2 forms a lateral support between the two side plates, which can directly offset the lateral force on the side plate, avoid deformation of the side plate, and thus maintain the effective constraint of the pressure block on the photovoltaic module.

[0051] Currently, the contact surfaces between the current pressure block body 1 and the photovoltaic module frame 3 are smooth planes, lacking constraint, making it easy for slippage to occur between the photovoltaic module frame 3 and the pressure block body 1, resulting in unstable installation of the photovoltaic module. To solve the above problem, the photovoltaic system of this utility model also includes an anti-slip structure on the contact surface between the pressure block body 1 and the photovoltaic module frame 3. The anti-slip structure can increase the friction between the pressure block body 1 and the photovoltaic module frame 3, effectively preventing slippage between the photovoltaic module frame 3 and the pressure block body 1, thereby improving the installation stability of the photovoltaic module. More specifically, anti-slip structures are provided on the wall surface where the pressure plate 14 contacts the photovoltaic module frame 3, and / or the wall surface where the first side plate 12 contacts the photovoltaic module frame 3, and / or the wall surface where the connecting plate 11 contacts the base layer 6, and / or the wall surface where the second side plate 13 contacts the photovoltaic module frame 3.

[0052] When an anti-slip structure is provided on the wall surface where the connecting plate 11 contacts the base layer 6, the friction between the pressure block body 1 and the base layer 6 can be increased, preventing the pressure block body 1 from shifting and enhancing the reliability of the connection.

[0053] When anti-slip structures are provided on the wall surface where the first side plate 12 contacts the photovoltaic module frame 3, and on the wall surface where the connecting plate 11 contacts the base layer 6, the friction between the pressure block body 1 and the photovoltaic module can be increased, preventing the photovoltaic module from rotating.

[0054] Anti-slip structures can be configured in various forms, such as reinforcing ribs, grooves, or serrations, as long as they can increase friction.

[0055] In some embodiments, the opening of the frame structure is covered with a snap cover 4, which is an elastic decorative snap cover to enhance aesthetics.

[0056] Combination Figure 7 As shown, when there are two pressure plates 14, the side walls of the two pressure plates 14 are respectively provided with a first snap-fit ​​part, and the inner side wall of the cover 4 is provided with two second snap-fit ​​parts. The second snap-fit ​​parts of the cover 4 are respectively engaged with the first snap-fit ​​parts of the pressure plates 14, thereby realizing the connection of the cover 4.

[0057] Combination Figure 8 As shown, when there is one pressure plate 14, a first snap-fit ​​part is provided on the side wall of the pressure plate 14 and on the side wall of the first side plate 12 or the second side plate 13, and two second snap-fit ​​parts are provided on the inner side wall of the cover 4. The second snap-fit ​​parts of the cover 4 are respectively engaged with the first snap-fit ​​parts to achieve the connection of the cover 4.

[0058] According to an embodiment of the present invention, in a second aspect, a photovoltaic system is provided, combined with... Figure 9 As shown, the system includes photovoltaic module mounting blocks and photovoltaic modules. Multiple photovoltaic module mounting blocks are provided and are positioned on a base layer 6, which can be a steel structure. The base layer 6 has positioning holes, and the photovoltaic module mounting blocks are fixedly connected to the base layer 6 via bolts or other fasteners passing through these holes, ensuring the stability and reliability of the photovoltaic module mounting blocks.

[0059] Multiple photovoltaic modules are provided, each including a photovoltaic module panel 5 and a photovoltaic module frame 3, the frame 3 being an aluminum alloy frame. Each photovoltaic module panel 5 has its two ends positioned on two photovoltaic module frames 3, which are connected to the base layer 6 and are restrained by photovoltaic module mounting blocks.

[0060] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
