Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to a photovoltaic module fixing structure. Background Technology

[0002] The existing fixing structure of photovoltaic modules is basically a combination of horizontal and inclined beam guide rails and pressure blocks. The pressure blocks fix the modules to the guide rails with screws. During construction, the nuts must be fixed first, the bolts must be inserted and the module position must be placed, and then the bolts must be fixed. This makes the whole process cumbersome and affects the construction efficiency.

[0003] For ease of installation, a snap-fit ​​structure is also used. Referring to Chinese utility model patent CN219499263U, a guide rail connection snap-fit ​​is disclosed, including a base and rotating arms. Rotating arms are rotatably connected to opposite sides of the base. A first mounting hole is formed between the two rotating arms on the base. The two rotating arms can rotate towards each other to retract, allowing the base to be inserted into the guide rail's slot from top to bottom. The two rotating arms can also rotate away from each other to unfold, allowing the base to be secured in the guide rail's slot via the rotating arms. However, this structure requires fasteners to connect the pressure block and the guide rail connection snap-fit, and finally, the fasteners need to be tightened to secure the base in the guide rail's slot via the rotating arms, while simultaneously locking the pressure block and the guide rail connection snap-fit, clamping the photovoltaic panel between the guide rail and the pressure block. This makes the operation time-consuming and labor-intensive. Utility Model Content

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a fast-installation photovoltaic module fixing structure and photovoltaic system. The clamping block eliminates the need for bolts or other fasteners, enabling rapid installation and fixing of photovoltaic modules.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] First, a fast-installation photovoltaic module fixing structure is provided, which includes a guide rail and a clamping block for fixing the photovoltaic module on the guide rail. The guide rail is provided with a fixing groove, and the lower part of the clamping block is provided with a buckle. The lower part of the clamping block is inserted into the fixing groove and fixed to the fixing groove by the buckle. The upper part of the clamping block is provided with a pressing head, which presses against the frame of the photovoltaic module while the buckle is fixed to the fixing groove.

[0007] Preferably, the buckle includes a latching protrusion and a spring that pushes the latching protrusion to engage with the fixing groove.

[0008] Preferably, the pressure block clamp includes two clamping arms hinged by a screw bolt, the locking protrusion is provided at the bottom of the clamping arms and protrudes outward, the spring is a compression spring and is provided between the two clamping arms, or the spring is a torsion spring and is connected to the screw bolt and the two clamping arms, and the two clamping arms are pushed outward by the spring.

[0009] Preferably, the clamping arm has an outwardly extending oblique section above the hinge, and the pressure head is connected to the upper end of the oblique section.

[0010] Preferably, the clamping arm has a force-applying protrusion above the pressure head.

[0011] Preferably, the pressure head has a rectangular structure, with its width extending inward toward the inside of the clamping arm and its length extending toward the opposite sides of the clamping arm.

[0012] Preferably, the bottom of the fixing groove has fastening grooves on both sides that engage with the card protrusion.

[0013] Preferably, the fixing groove has guide slopes on opposite sides above the buckle groove to guide the lower part of the pressure block clamp to be inserted.

[0014] Preferably, the bottom surface of the pressure head is provided with a rubber pad layer, which is used to increase the friction between the pressure head and the frame of the photovoltaic module.

[0015] Secondly, a photovoltaic system is also provided, including a photovoltaic module and a fixing structure for the photovoltaic module.

[0016] The present invention adopts the above technical solution and has the following beneficial effects:

[0017] 1. A clamping fixture secures the photovoltaic module to a guide rail. The guide rail has a fixing groove, and the lower part of the clamping fixture has a buckle. The lower part of the clamping fixture inserts into the fixing groove and is fixed to the fixing groove by the buckle. The upper part of the clamping fixture has a pressure head for pressing the photovoltaic module frame. The clamping fixture is a single, integral structural component, with its lower part inserted into the fixing groove and fixed to the groove by the buckle. It is understood that, to ensure the buckle is fixed to the fixing groove while the pressure head of the clamping fixture presses against the photovoltaic module frame, based on basic common sense, the distance L2 between the buckle and the pressure head can be designed to correspond to the distance L1 from the fixing groove and buckle mating position to the A-side of the photovoltaic module frame. Therefore, while the buckle is fixed to the fixing groove, the pressure head of the clamping fixture presses against the photovoltaic module frame. This eliminates the need for clamping bolts or other fasteners, enabling quick installation and fixation of the photovoltaic module.

[0018] 2. The buckle includes a latching protrusion and a spring that pushes the latching protrusion to engage with the fixing groove. The pressure block clamp includes two clamping arms hinged by a bolt. The latching protrusion is located at the bottom of the clamping arm and protrudes outward. The spring is a compression spring located between the two clamping arms, or the spring is a torsion spring connected to the bolt and the two clamping arms. The bottom of the fixing groove has corresponding locking grooves on opposite sides to engage with the latching protrusion. A high-strength spring can be used. Therefore, during the insertion of the lower part of the pressure block clamp into the fixing groove, the spring can be compressed by squeezing the upper ends of the two clamping arms, causing the lower parts of the two clamping arms to close inward. When the lower part of the clamp is fully inserted into the fixing groove, the latching protrusion and the locking groove are aligned. When the upper ends of the two clamping arms are released, the spring pushes the lower parts of the two clamping arms to open outward, and the latching protrusion engages with the locking groove, thus achieving fixation.

[0019] 3. Since the clamping arm has an outwardly extending oblique section above the hinge, and the pressure head is connected to the upper end of the oblique section, the upper ends of the two clamping arms can be separated by a certain distance. Thus, by operating at the upper end of the clamping arm, the lower parts of the two clamping arms can be opened or closed. In the fixed state, the two pressure heads are spaced a certain distance apart, which is beneficial for pressing the photovoltaic module.

[0020] 4. In order to facilitate the application of force to the upper end of the clamping arm, the clamping arm is provided with a force-applying protrusion above the pressure head. When installing the pressure block clamp, the force is applied through the force-applying protrusion, causing the upper parts of the two clamping arms to close together in the middle, and the lower parts to close together in the middle at the same time, so that the lower part of the pressure block clamp can be inserted into the fixing groove.

[0021] 5. The pressure head has a rectangular structure, extending inwards along the width of the clamping arm and along its length to the opposite sides of the clamping arm. This ensures the pressure head has sufficient width to guarantee the interaction area with the photovoltaic module frame. Furthermore, both ends of the pressure head can interact with the frames of two adjacent photovoltaic modules.

[0022] 6. Since the fixing groove has guide slopes on opposite sides above the buckle groove to guide the lower part of the pressure block clamp to insert, the lower part of the pressure block clamp is guided by the guide slopes during the insertion of the fixing groove until it is fully inserted. Finally, the lower parts of the two clamping arms open outward under the action of the spring, so that the buckle is engaged in the buckle groove.

[0023] 7. The bottom surface of the pressure head is provided with a rubber pad layer, which is bonded to the bottom surface of the pressure head. The rubber pad layer is used to increase the friction between the pressure head and the frame of the photovoltaic module.

[0024] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0032] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0033] Those skilled in the art will understand that, without conflict, the features in the following embodiments and implementations can be combined with each other.

[0034] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. For example, terms such as "upper," "lower," "lateral," and "longitudinal," which indicate orientation or positional relationship, are based solely on the orientation or positional relationship shown in the accompanying drawings and are used only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device / component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0037] Based on existing technology, photovoltaic modules are installed on guide rails, which can be horizontal beam guide rails or inclined beam guide rails. The guide rails can be fixed to the sloping roof or other installation positions by hooks to fix the photovoltaic modules. The guide rails are U-shaped with a fixing groove in the middle for fixing with the pressure block clamps.

[0038] To avoid using fasteners such as clamping bolts, clamping fixtures are used to quickly install and secure photovoltaic modules. For example... Figures 1 to 4 As shown, this embodiment provides a fast-installation photovoltaic module fixing structure, which includes a guide rail 2 and a pressure clamp 1 for fixing the photovoltaic module 3 on the guide rail 2. The pressure clamp adopts an integral structural component. The guide rail 2 is provided with a fixing groove 21. The lower part of the pressure clamp 1 is provided with a buckle. The lower part of the pressure clamp 1 is inserted into the fixing groove 21 and fixed to the fixing groove 21 by the buckle. The upper part of the pressure clamp 1 is provided with a pressure head 16 for pressing the photovoltaic module frame.

[0039] The clamping device is a single, integral component. Its lower part inserts into a fixing slot and is secured to the slot via a snap-fit ​​mechanism. To ensure the snap-fit ​​is fixed to the slot, the upper clamping head presses against the photovoltaic module frame. Based on common sense, the distance L2 between the snap-fit ​​and the clamping head can be designed to correspond to the distance L1 from the point where the snap-fit ​​mates with the fixing slot to surface A 31 of the photovoltaic module frame. Therefore, while the snap-fit ​​is secured to the slot, the upper clamping head presses against the photovoltaic module frame. This eliminates the need for clamping bolts or other fasteners, enabling rapid installation and fixation of the photovoltaic module.

[0040] In some embodiments, the latch includes a latching protrusion 14 and a spring 13 that pushes the latching protrusion 14 into the fixing groove 21. The clamping block 1 includes two clamping arms 11 hinged together by a bolt 12, with the hinge located at the midpoint of the height of the two clamping arms, allowing the two clamping arms to rotate around the bolt. The latching protrusion 14 is located at the bottom of the clamping arms and protrudes outward. The spring 13 is a compression spring located between the two clamping arms 11, or the spring is a torsion spring connected to the bolt 12 and the two clamping arms 11, pushing the two clamping arms outward. The bottom of the fixing groove 21 has corresponding latching grooves 22 on opposite sides that engage with the latching protrusion. High-strength springs can be used. Therefore, during the insertion of the lower part of the clamping block into the fixing groove, the springs are compressed by squeezing the upper ends of the two clamping arms, causing the lower parts of the two clamping arms to close inwards. When the lower part of the clamp is fully inserted into the fixing groove, the locking protrusion aligns with the snap-fit ​​groove. Releasing the upper ends of the two clamping arms allows the springs to push the lower parts of the two clamping arms outwards, thus engaging the locking protrusion into the snap-fit ​​groove, achieving fixation. High-strength springs can be used to ensure that the locking protrusion is not easily separated after engaging the snap-fit ​​groove, offering advantages such as high reliability, convenient installation and use, and high safety.

[0041] Furthermore, the clamping arm 11 has an outwardly extending inclined section 15 above the hinge portion. The pressure head 16 is connected to the upper end of the inclined section, allowing the upper ends of the two clamping arms to be separated by a certain distance. This allows operation at the upper end of the clamping arms to open or close the lower parts of the two clamping arms. In the fixed state, the two pressure heads are spaced a certain distance apart, which is beneficial for pressing the photovoltaic module. In addition, the middle part of the clamping arm is roughly triangular in shape, with the apex of both parts connected to the screw bolt.

[0042] To facilitate the application of force to the upper end of the clamping arm, the clamping arm 11 is provided with a force-applying protrusion 17 above the pressure head 16. When installing the pressure block clamp, the force is applied through the force-applying protrusion, causing the upper parts of the two clamping arms to close together in the middle, and the lower parts to also close together in the middle, so that the lower part of the pressure block clamp can be inserted into the fixing groove.

[0043] Specifically, the pressure head 16 has a rectangular structure, extending inwards along the width of the clamping arm and inwards along its length to the opposite sides of the clamping arm. Taking its installation on the crossbeam guide rail as an example, its width is longitudinal and its length is transverse. This allows the pressure head to have sufficient width to ensure the effective contact area with the photovoltaic module frame. Furthermore, both ends of the pressure head can interact with the frames of two adjacent photovoltaic modules.

[0044] Furthermore, the fixing groove 21 has guide ramps 23 on opposite sides above the buckle groove to guide the lower part of the pressure block clamp to insert. Therefore, the middle of the fixing groove is a trapezoidal groove. During the process of inserting the lower part of the pressure block clamp into the fixing groove, it is guided by the guide ramps until it is fully inserted. Finally, the lower parts of the two clamping arms open outward under the action of the spring, so that the clamping protrusions are engaged in the buckle groove.

[0045] Furthermore, the bottom surface of the pressure head 16 is provided with a rubber pad layer, which is bonded to the bottom surface of the pressure head. The rubber pad layer is used to increase the friction between the pressure head and the frame of the photovoltaic module.

[0046] like Figure 5 As shown, in some embodiments, the structure of two clamping arms hinged by bolts and equipped with springs may not be used. Instead, the elastic deformation of the elastic legs generates force to engage the locking protrusion with the locking groove. Specifically, the lower two sides of the pressure block clamp 1 are provided with elastic legs 18, and the bottom outer side of the elastic legs is provided with a locking protrusion 14. The elastic force of the elastic legs allows the locking protrusion to engage with the locking groove. Alternatively, a spring is provided between the locking protrusion and the elastic legs. During the insertion of the lower part of the pressure block clamp into the fixing groove, the spring contracts, and when the locking protrusion aligns with the locking groove, the locking protrusion engages with the locking groove under the action of the spring.

[0047] Specifically, the clamping arm 11 is made of high-strength zinc-aluminum-magnesium material, for example, it is an integral structure, and can be mass-produced by sheet metal bending process or die stamping.

[0048] In addition, the guide rail 2 has support surfaces 24 on both sides of the opening of the fixing groove, which are used to cooperate with the C-side 32 of the photovoltaic module frame.

[0049] The clamping block fixture in this embodiment can be applied to the installation of photovoltaic power station brackets on sloping roofs. In photovoltaic power stations where there is a need, installing this clamping block fixture enables the rapid installation and fixing of photovoltaic modules, thereby improving the construction efficiency of photovoltaic modules.

[0050] The above description is merely a specific embodiment of the utility model, but the scope of protection 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 accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
