Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel pressing technology, specifically to a photovoltaic module pressing block, an installation structure, and a photovoltaic power plant. Background Technology

[0002] With the continuous optimization of the global energy structure, photovoltaic power generation, as a clean and renewable energy source, has been widely promoted and applied. As the core component of a photovoltaic power generation system, the installation quality of photovoltaic modules directly affects the operational stability and power generation efficiency of the entire system. To ensure that photovoltaic modules are firmly fixed during long-term operation and to prevent displacement or detachment due to wind loads, snow loads, or other external forces, specialized clamps are typically used for pressing and positioning.

[0003] Photovoltaic module clamps are typically placed at the edge of the photovoltaic module. One type of clamp includes a clamp body and a crossbeam. The clamp body has a U-shaped structure with screw holes at the bottom. The crossbeam is placed horizontally at the bottom of the clamp body and secured with bolts and nuts. The crossbeam and clamp plate fix the photovoltaic module from both sides. However, this type of clamp has a small contact area with the photovoltaic module, and in windy weather, the clamp and crossbeam are prone to rotation and displacement, and the fasteners can easily loosen, resulting in insecure clamping of the photovoltaic module, or even detachment. Utility Model Content

[0004] In view of this, the present invention provides a photovoltaic module clamping block, an installation structure, and a photovoltaic power plant to solve the problem of photovoltaic modules being loosely clamped and detaching in strong winds or extreme environments.

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

[0006] Two fastening blocks are spaced apart along a first direction, and an installation channel is formed between the two fastening blocks. Each fastening block includes: a first base plate, two first side plates, and two pressure plates. The two first side plates are arranged opposite to each other. The first base plate is located between the two first side plates, and both ends of the first base plate are respectively connected to the bottom ends of the two first side plates. The pressure plate is provided on the side of each first side plate away from the first base plate, and one end of the pressure plate is connected to the top end of the first side plate. The first direction is parallel to the length direction of the first side plate.

[0008] Beneficial effects

[0009] The connector links the two fastening blocks into a single unit, improving the structural stability of the photovoltaic module clamping block. A receiving groove at the bottom of the connector allows for the embedding of a crossbeam, and the connector effectively limits the movement of the crossbeam. Simultaneously, the photovoltaic module is installed between the two clamping plates and the crossbeam, resulting in a large contact area. Therefore, the fit between the photovoltaic module clamping block and the crossbeam is more robust, and the larger contact area with the photovoltaic module enhances the clamping block's resistance to detachment under high wind or snow loads.

[0010] In one optional embodiment, the connector includes: a second base plate and two second side plates, the top surfaces of the two second side plates being connected to the bottom surfaces of the two first base plates respectively, the second base plate being disposed between the two second side plates, and the two ends of the second base plate being connected to the two second side plates respectively, the second base plate and the two second side plates together forming the receiving groove with an open top.

[0011] In one alternative embodiment, a first through hole is provided on the second base plate.

[0012] In one alternative embodiment, the second base plate and the second side plate are perpendicular to each other.

[0013] Beneficial effects

[0014] The second base plate and the second side plate are perpendicularly connected to each other, ensuring the structural strength and rigidity of the connector, and the receiving groove also has better geometric stability.

[0015] In one alternative embodiment, the pressure plate is provided with anti-slip serrations on the side near the first base plate.

[0016] Beneficial effects

[0017] Anti-slip serrations can significantly enhance the friction between photovoltaic modules and the pressure plate, preventing the photovoltaic modules from slipping or shifting under the action of external forces such as wind and vibration, and improving clamping stability.

[0018] In one alternative embodiment, the first base plate is perpendicular to the first side plate, and the first side plate is perpendicular to the pressure plate.

[0019] Beneficial effects

[0020] The first base plate and the first side plate are perpendicular to each other, and the first side plate and the pressure plate are also perpendicular to each other, which enhances the structural strength and stability of the fastening block, and also improves the compressive strength and deformation resistance of the photovoltaic module block.

[0021] In one alternative embodiment, the fastening block and the connector are integrally die-cast.

[0022] Secondly, this utility model also provides a photovoltaic module installation structure, including the photovoltaic module pressure block and the crossbeam. The crossbeam is disposed in the receiving groove of the connector, and a second through hole is provided on the crossbeam. Fasteners are provided at the first through hole and the second through hole.

[0023] Beneficial effects

[0041] 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.

[0042] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0043] According to an embodiment of the present invention, a photovoltaic module clamping block is provided, comprising: two fastening clamping blocks 1 and a connector 2. The two fastening clamping blocks 1 are spaced apart along a first direction, and an installation channel is formed between the two fastening clamping blocks 1. Each fastening clamping block 1 comprises: a first base plate 11, two first side plates 12 and two pressure plates 13. The two first side plates 12 are arranged opposite to each other. The first base plate 11 is located between the two first side plates 12, and both ends of the first base plate 11 are respectively connected to the bottom ends of the two first side plates 12. A pressure plate 13 is provided on the side of each first side plate 12 away from the first base plate 11, and one end of the pressure plate 13 is connected to the top end of the first side plate 12. The first direction is parallel to the length direction of the first side plate 12. The top surface of the connector 2 is connected to the bottom surface of the two first base plates 11. The connector 2 has a receiving groove 21, which communicates with the installation channel. The receiving groove 21 is suitable for placing a crossbeam 3.

[0044] The fastening block 1 is formed by connecting the first base plate 11, two first side plates 12, and two pressure plates 13 to form a U-shaped cross-section. This effectively disperses the stress on the photovoltaic module block, preventing local stress concentration and thus avoiding deformation of the photovoltaic module block or loosening of the photovoltaic module 6. The connector 2 connects the two first base plates 11, thereby connecting the two fastening blocks 1 into a whole, enhancing the rigidity and overall coordination of the photovoltaic module block. The photovoltaic module 6 is installed under the two fastening blocks 1, increasing the fixed contact area of ​​the photovoltaic module 6 and preventing loosening. The connector 2 has an internal receiving groove 21 located directly below the installation channel, facilitating the installation of the crossbeam 3 into the receiving groove 21 through the installation channel. The length direction of the crossbeam 3 is perpendicular to the length direction of the photovoltaic module block. The connector 2 limits the crossbeam 3, ensuring its stable positioning and preventing lateral or vertical displacement.

[0045] In one embodiment, the connector 2 includes a second base plate 22 and two second side plates 23. The top surfaces of the two second side plates 23 are respectively connected to the bottom surfaces of the two first base plates 11. The second base plate 22 is disposed between the two second side plates 23, and both ends of the second base plate 22 are respectively connected to the two second side plates 23. The second base plate 22 and the two second side plates 23 together form an accommodating groove 21 with an open top.

[0046] The opening of the receiving groove 21 faces upward, which facilitates the quick insertion of the crossbeam 3 from above. The cross-sectional shape and size of the receiving groove 21 are designed to match the specifications of the crossbeam 3, ensuring that the crossbeam 3 will not shake or shift after placement, thereby improving the connection stability and safety between the photovoltaic module pressing block and the crossbeam 3.

[0047] In one embodiment, a first through hole 24 is provided on the second base plate 22.

[0048] The first through hole 24 is located at the center of the second base plate 22. The diameter of the first through hole 24 is matched to the size of the fastener 5 used to prevent excessive gaps between the fastener 5 and the first through hole 24, which could cause the crossbeam 3 to loosen. Reinforcing ribs or washers are optionally fitted around the through hole to enhance its compressive strength and prevent local deformation of the second base plate 22 during the tightening of the fastener 5. The first through hole 24 facilitates the subsequent connection of the fastener 5 to the crossbeam 3.

[0049] In one embodiment, the second base plate 22 and the second side plate 23 are perpendicular to each other.

[0050] The perpendicularity between the second base plate 22 and the second side plate 23 gives the receiving groove 21 good three-dimensional stability, which can provide lateral and vertical clamping and support for the crossbeam 3, and prevent the crossbeam 3 from shifting or tilting due to load or external force.

[0051] In one embodiment, the first base plate 11 is perpendicular to the first side plate 12, and the first side plate 12 is perpendicular to the pressure plate 13.

[0052] The vertical connection between the first base plate 11 and the first side plate 12, as well as between the first side plate 12 and the pressure plate 13, provides a clear force transmission path for the fastening block 1. Specifically, when the pressure plate 13 applies clamping force to the photovoltaic module 6, the resulting load can be transmitted to the first base plate 11 through the first side plate 12 and further distributed to the connector 2, thereby improving the compressive strength and deformation resistance of the entire photovoltaic module clamping block.

[0053] In one embodiment, the pressure plate 13 is provided with anti-slip serrations 4 on the side near the first base plate 11.

[0054] The anti-slip serration 4 increases the friction between the pressure plate 13 and the photovoltaic module 6. When the pressure plate 13 presses down on the photovoltaic module 6, it effectively increases the static friction between the pressure plate 13 and the photovoltaic module 6. The anti-slip serration 4 can be triangular, sawtooth, or wavy. In this embodiment, a wavy anti-slip serration 4 is selected.

[0055] In one embodiment, the fastening block 1 and the connector 2 are integrally die-cast.

[0056] The photovoltaic module briquettes are manufactured using an integrated die-casting process. High-strength alloy materials are selected, and the photovoltaic module briquettes are die-cast using die-casting molds, which improves the structural stability and manufacturing precision of the photovoltaic module briquettes.

[0057] According to an embodiment of this utility model, a photovoltaic module mounting structure is also provided, including a photovoltaic module clamping block and a crossbeam 3. The structure of the photovoltaic module clamping block is the same as that of the photovoltaic module clamping block in the above embodiment, so it will not be described again. The crossbeam 3 is disposed in the receiving groove 21 of the connector 2, and a second through hole is provided on the crossbeam 3. Fasteners 5 are provided at the first through hole 24 and the second through hole.

[0058] A second through hole is formed on the surface of the crossbeam 3, and the position of the second through hole corresponds to the position of the first through hole 24 on the second base plate 22. During installation, the photovoltaic module clamping block is placed on the photovoltaic module 6, with one edge of the photovoltaic module 6 abutting the bottom of the pressure plate 13 and the end of the photovoltaic module 6 abutting the outer side of the first side plate 12. Then, the crossbeam 3 is inserted into the receiving groove 21, and the second base plate 22 and the two second side plates 23 abut against the bottom surface and two sides of the crossbeam 3, respectively. The first through hole 24 is aligned with the second through hole, and then the fastener 5 is passed through the first through hole 24 and the second through hole and locked. Multiple photovoltaic module clamping blocks can be connected to one edge of a photovoltaic module 6 to achieve the clamping of the photovoltaic module 6.

[0059] When the photovoltaic module installation structure is in use, the pressure plate 13 applies pressure to the upper edge of the photovoltaic module 6, and the crossbeam 3 provides support for the lower side of the photovoltaic module 6, thereby achieving stable clamping of the photovoltaic module 6 and ensuring that the photovoltaic module installation structure has good wind resistance, earthquake resistance and deformation resistance.

[0060] According to an embodiment of the present invention, a photovoltaic power plant is also provided, including multiple photovoltaic module installation structures, which are spaced apart, and a photovoltaic module 6 is disposed between two adjacent photovoltaic module installation structures along a second direction, wherein the second direction is perpendicular to the first direction.

[0061] Multiple photovoltaic module installation structures are arranged in an array along a first direction and a second direction, and a photovoltaic module 6 can be installed between two adjacent photovoltaic module installation structures along the second direction. Through the regular and orderly connection of multiple photovoltaic module installation structures and multiple photovoltaic modules 6, a photovoltaic power plant is formed on the site, enhancing the photovoltaic power plant's resistance to deformation and operational reliability under natural forces such as wind load and snow load.

[0062] In one embodiment, the photovoltaic module 6 includes a photovoltaic panel 61 and a photovoltaic frame 62, the photovoltaic frame 62 being disposed around the photovoltaic panel 61 and sandwiched between the pressure plate 13 and the crossbeam 3.

[0063] A photovoltaic frame 62 is fitted around the perimeter of the photovoltaic panel 61, providing protection during installation. The frame 62 is made of aluminum alloy, offering lightweight construction and good rigidity, effectively protecting the photovoltaic panel 61 and fitting the photovoltaic module clamping block. During installation, the photovoltaic frame 62 is inserted between the photovoltaic module clamping block and the crossbeam 3. The bottom surface of the clamping plate 13 and the top surface of the crossbeam 3 abut against the upper and lower sides of the photovoltaic frame 62, respectively, clamping the photovoltaic module 6 in place.

[0064] Installation process of photovoltaic module 6: First, remove two photovoltaic module clamping blocks. Place the bottom surface of one side plate 13 of the two photovoltaic module clamping blocks against the left and right edges of the photovoltaic module 6 frame, respectively. The openings of the receiving grooves 21 of the two photovoltaic module clamping blocks are aligned in a straight line. The photovoltaic module 6 frame is located below the clamping plate 13, and the two ends of the photovoltaic module 6 frame abut against the first side plates 12 of the two photovoltaic module clamping blocks. Next, remove the crossbeam 3 and align it with the receiving grooves 21 on the two photovoltaic module clamping blocks. The second through hole on the crossbeam 3 aligns with the first through hole 24 on the second base plate 22. Use fasteners 5 to tighten the connection to achieve a stable connection between the photovoltaic module clamping blocks, photovoltaic module 6, and crossbeam 3.

[0065] 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.
