Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel installation technology, and more specifically, to a photovoltaic panel assembly press-fitting structure. Background Technology

[0002] Photovoltaic panels are typically composed of multiple photovoltaic panels, with each pair of panels being pressed and secured together using a clamping block. In existing technologies, photovoltaic module clamping blocks, roof components, and roof structures are used. The clamping block assembly is installed in an inverted "U" shape. Bolts penetrate the middle of the "U" shape of the clamping block and are placed in the guide rail groove on the lower side, connecting with the screw hole in the middle of the lower pad. Then, by rotating the bolts, the clamping block is pulled to the two hooked parts on both sides of the upper end of the guide rail groove. The two wings of the lower pad clamp the two hooked parts on both sides of the upper end of the guide rail groove, ultimately achieving the clamping of the photovoltaic module.

[0003] However, the lower pads in current clamping block structures are all flat. This causes the lower pad to rotate during installation due to the rotation of the bolts within the guide rail groove. Consequently, the contact area between the lower pad's two wings and the hooks at the upper end of the guide rail groove is too small or not properly secured, ultimately leading to the photovoltaic panel loosening. At this point, a worker must hold the lower pad with one hand and use a torque wrench to tighten the bolts again. Therefore, this poses a safety hazard to personnel and the photovoltaic panel during installation, requires multiple reinstallation steps for the clamping block, and significantly reduces efficiency.

[0004] In summary, how to provide a press-fit structure that allows installers to successfully install the press components in one go is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a photovoltaic panel module press-fitting structure that can quickly and in one go install the press-fitting structure into place, thereby improving installation efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A photovoltaic panel module press-fitting structure, comprising:

[0008] The upper pressure plate has an inverted V-shaped cross-section and is provided with through holes;

[0009] The guide rail groove is located below the upper pressure plate and contacts the upper pressure plate. Both sides of the guide rail groove at the contact position with the upper pressure plate are provided with protrusions.

[0010] The lower pad is located inside the guide rail groove. The lower pad has a threaded hole and a slot that mates with the protrusion. When the protrusion is placed inside the slot, the lower pad is limited in position.

[0011] The locking bolt, when it passes through the through hole on the upper pressure plate and engages with the threaded hole, locks the lower pad, the upper pressure plate and the guide rail groove together.

[0012] Furthermore, in this invention, the protrusion has a barb-shaped structure, and the lower pad has a U-shaped cross-section.

[0013] Furthermore, the present invention provides two slots, which are located on both sides of the lower pad, and the cross-section of the lower pad is W-shaped.

[0014] Furthermore, in this invention, the protrusion and the slot are interference-fitted.

[0015] Furthermore, this utility model also includes:

[0016] The lower pressure plate is located between the upper pressure plate and the guide rail groove. The lower pressure plate has placement platforms on both sides for placing photovoltaic panels.

[0017] Furthermore, the lower pressure plate is provided with a groove, and the upper pressure plate can slide inside the groove along the axis of the locking bolt.

[0018] Furthermore, in this invention, the lower pressure plate is provided with two limiting grooves at the contact position of the slide rail groove, and the two protrusions are placed inside the two limiting grooves.

[0019] Furthermore, the upper pressure plate of this utility model includes two pressing parts and a body, wherein the pressing parts are integrally formed with the body, and the angle between the pressing parts and the body is less than 10 degrees.

[0020] Furthermore, the present invention provides anti-slip pads at the contact positions of the pressing part and the photovoltaic panel, the contact positions of the placement platform and the photovoltaic panel, and the contact positions of the lower pad and the guide rail groove.

[0021] The photovoltaic panel assembly press-fitting structure provided by this utility model involves fixing the guide rail groove to the main beam at the installation position with bolts, then arranging the photovoltaic panels in the installation sequence, placing the guide rail groove between two adjacent photovoltaic panels, and supporting the photovoltaic panels with the guide rail groove. The upper pressure plate is inserted into the gap between the two photovoltaic panels, and the lower pad is manually placed inside the guide rail groove and below the upper pressure plate. Both sides of the contact position between the guide rail groove and the upper pressure plate are provided with protrusions, and the lower pad is provided with a groove that mates with the protrusions. When the protrusion is placed in the groove... The lower pad is positioned to limit its movement. The locking bolt passes through the through hole on the upper pressure plate and engages with the threaded hole, locking the lower pad, upper pressure plate, and guide rail groove together. In other words, the locking bolt secures the lower pad, upper pressure plate, and guide rail groove together. At the same time, the protrusion on the guide rail groove and the slot on the lower pad engage to fix the position of the lower pad, effectively preventing the upper pressure plate from failing to secure the photovoltaic panel due to the rotation of the lower pad with the bolt. This improves the installation efficiency for maintenance personnel and eliminates the need for secondary installation. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The core of this utility model is to provide a photovoltaic panel module press-fitting structure that can quickly and in one go install the press-fitting structure into place, thereby improving installation efficiency.

[0031] Please refer to Figures 1-4 A photovoltaic panel module press-fitting structure includes an upper pressure plate 1, a guide rail groove 5, a lower pad 4, and a locking bolt 2. The upper pressure plate 1 has an inverted V-shaped cross-section and a through hole 101. The guide rail groove 5 is located below the upper pressure plate 1 and contacts the upper pressure plate 1. Both sides of the contact position between the guide rail groove 5 and the upper pressure plate 1 are provided with protrusions 501. The lower pad 4 is located inside the guide rail groove 5 and has a threaded hole 401. The lower pad 4 also has a slot 402 that mates with the protrusions 501. When the protrusions 501 are placed inside the slot 402, the lower pad 4 is limited. The locking bolt 2 passes through the through hole 101 on the upper pressure plate 1 and is threadedly engaged with the threaded hole 401 to lock the lower pad 4, the upper pressure plate 1, and the guide rail groove 5.

[0032] It should be noted that the shapes of the protrusion 501 and the slot 402 are not specifically limited in this embodiment.

[0033] In some embodiments, the protrusion 501 has a barb-shaped structure, and the lower pad 4 has a U-shaped cross-section. Specifically, the lower pad 4 has a U-shaped cross-section, that is, the slot 402 is a U-shaped groove on the lower pad 4. The lower pad 4 is limited by the engagement between the flanges on both sides of the lower pad 4 and the protrusion 501.

[0034] In other embodiments, the protrusion 501 has a serrated structure, and the slot 402 is a structure that cooperates with the protrusion 501. The engagement between the protrusion 501 and the slot 402 achieves the function of limiting the lower pad 4.

[0035] In other embodiments, the protrusion 501 has a barb-shaped structure and there are two slots 402. The two slots 402 are located on both sides of the lower pad 4, and the cross-section of the lower pad 4 is W-shaped. That is, when the protrusion 501 is placed inside the two slots 402 on the lower pad 4, the function of limiting the lower pad 4 is realized.

[0036] Optionally, to further facilitate installation by workers, in some embodiments, the protrusion 501 and the slot 402 are interference-fitted. Specifically, a rubber layer is provided on the contact surface between the slot 402 and the protrusion 501. When the slot 402 and the protrusion 501 are engaged, the interference fit is achieved through the deformation of the rubber layer. At the same time, the rubber layer has the effect of increasing friction. When installing the lower pad 4, the worker only needs to insert the slot 402 on the lower pad 4 into the protrusion 501 to fix it, avoiding the need for the worker to hold it by hand during the installation process, which helps to improve installation efficiency.

[0037] Optionally, based on the above embodiments, the rubber layer can be fixed to the lower pad by adhesive bonding or by screws.

[0038] In other embodiments, a magnet extending along the direction of the guide rail groove 5 is provided at the contact position between the guide rail groove 5 and the lower pad 4, and strong magnets are installed on both sides of the lower pad 4. During installation, the worker only needs to place the lower pad 4 at the required installation position, and the lower pad 4 can be fixed to the guide rail groove 5 by the attraction between the magnets. This avoids the need for the worker to hold the lower pad 4 by hand until it is connected to the locking bolt 2 during the installation process, further improving the installation efficiency. The attraction between the magnets can also prevent the lower pad 4 from rotating during the locking process between the locking bolt 2 and the lower pad 4, which is conducive to improving the installation efficiency.

[0039] In use, the guide rail groove 5 is fixed to the main beam at the installation position with bolts. Then, the photovoltaic panels 6 are arranged in the installation sequence, with the guide rail groove 5 placed between two adjacent photovoltaic panels 6, supporting the photovoltaic panels 6. The upper pressure plate 1 is inserted into the gap between the two photovoltaic panels 6. The lower pad 4 is manually placed inside the guide rail groove 5 and below the upper pressure plate 1. Both sides of the contact position between the guide rail groove 5 and the upper pressure plate 1 are provided with protrusions 501. The lower pad 4 is provided with a slot 402 that mates with the protrusions 501. When the protrusions 501 are placed inside the slots 402, the lower pad 4 is secured. The locking bolt 2 passes through the through hole 101 on the upper pressure plate 1 and engages with the threaded hole 401, thereby locking the lower pad 4, the upper pressure plate 1 and the guide rail groove 5 together. In other words, the locking bolt 2 fixes the lower pad 4, the upper pressure plate 1 and the guide rail groove 5 together. At the same time, the protrusion 501 on the guide rail groove 5 and the slot 402 on the lower pad 4 engage to fix the position of the lower pad 4. This effectively prevents the lower pad 4 from rotating with the bolt and thus prevents the upper pressure plate 1 from being unable to fasten the photovoltaic panel 6, improving the installation efficiency of maintenance personnel and eliminating the need for secondary installation.

[0040] In some embodiments, a lower pressure plate 3 is also included. The lower pressure plate 3 is located between the upper pressure plate 1 and the guide rail groove 5. Placement platforms are provided on both sides of the lower pressure plate 3 for placing the photovoltaic panel 6. Specifically, the placement platform is a platform-shaped structure, and the side of the photovoltaic panel 6 is placed on it to support the photovoltaic panel 6.

[0041] In other embodiments, a placement platform can be provided on the guide rail groove 5, that is, a plate-shaped platform is provided on both sides of the guide rail groove 5, and the side of the photovoltaic panel 6 is placed on it to support the photovoltaic panel 6.

[0042] The placement platform can be integrally formed with the guide rail groove 5, or it can be installed on the guide rail groove 5 by bolt fixing.

[0043] In order to improve the pressing effect of the device on the photovoltaic panel 6 and adapt to photovoltaic panels 6 of different thicknesses, in some embodiments, the lower pressure plate 3 is provided with a groove 302, and the upper pressure plate 1 can slide inside the groove 302 along the axis of the locking bolt 2. Specifically, the lower pressure plate 3 is provided with a groove 302 that cooperates with the upper pressure plate 1, so that the upper pressure plate 1 can slide inside the groove 302 along the axis of the locking bolt 2. This allows the upper pressure plate 1 to adjust its position according to the thickness of different photovoltaic panels 6. The groove 302 limits the upper pressure plate 1, thereby improving the pressing effect of the upper pressure plate 1 on the photovoltaic panel 6.

[0044] In other embodiments, a plurality of sliding rods extending along the axis of the locking bolt 2 can be provided on the lower pressure plate 3, and through holes 101 that cooperate with the sliding rods can be provided on the upper pressure plate 1, so that the upper pressure plate 1 can maintain a sliding action under the action of the sliding rods, thereby realizing the adjustment for photovoltaic panels 6 of different thicknesses.

[0045] To ensure the stability of the lower pressure plate 3 after installation, in some embodiments, the lower pressure plate 3 is provided with two limiting grooves 301 at the contact position with the slide rail groove, and two protrusions 501 are placed inside the two limiting grooves 301. That is to say, the two limiting grooves 301 and the slide rail groove form a limiting effect, which avoids the relative rotation of the lower pressure plate 3 during or after installation, and helps to improve the stability after installation.

[0046] To further improve the pressing effect on the photovoltaic panel 6, in some embodiments, the upper pressure plate 1 includes two pressing parts 103 and a body 102. The pressing parts 103 and the body 102 are integrally formed, and the included angle between the pressing parts 103 and the body 102 is less than 90 degrees. That is, an acute angle is set at the contact position between the upper pressure plate 1 and the photovoltaic panel 6. The acute angle gives it a pre-tightening force during the pressing process of the photovoltaic panel 6, which further improves the locking effect on the photovoltaic panel 6.

[0047] Optionally, in order to improve the connection stability between the pressing part 103 and the body 102, the cross-sectional area between the pressing part 103 and the body 102 can be increased, which is beneficial to improving the connection stability between the pressing part 103 and the body 102 and ensuring the pressing effect on the photovoltaic panel 6.

[0048] Optionally, in order to further increase the stability of the connection between the various components, in some embodiments, anti-slip pads are provided at the contact positions of the pressing part 103 and the photovoltaic panel 6, the contact positions of the placement platform and the photovoltaic panel 6, and the contact positions of the lower pad 4 and the guide rail groove 5. Anti-slip pads are provided at the positions where the various components are connected, thereby increasing the connection friction between the various components and thus improving the stability of the connection between the components.

[0049] In other words, the key point of this utility model is: the guide rail groove 5 is fixed to the main beam at the installation position with bolts, and then the photovoltaic panels 6 are arranged in the installation sequence. The guide rail groove 5 is placed between two adjacent photovoltaic panels 6, and the guide rail groove 5 supports the photovoltaic panels 6. The upper pressure plate 1 is inserted into the gap between the two photovoltaic panels 6. The lower pad 4 is manually placed inside the guide rail groove 5 and below the upper pressure plate 1. Both sides of the contact position between the guide rail groove 5 and the upper pressure plate 1 are provided with protrusions 501. The lower pad 4 is provided with a slot 402 that mates with the protrusions 501. When the protrusions 501 are placed inside the slots 402, the actual... The lower pad 4 is now positioned by locking bolt 2, which passes through the through hole 101 on the upper pressure plate 1 and engages with the threaded hole 401, thereby locking the lower pad 4, the upper pressure plate 1, and the guide rail groove 5. In other words, the lower pad 4, the upper pressure plate 1, and the guide rail groove 5 are fixedly connected by locking bolt 2. At the same time, the protrusion 501 on the guide rail groove 5 and the slot 402 on the lower pad 4 engage to fix the position of the lower pad 4, effectively preventing the lower pad 4 from rotating with the bolt and thus preventing the upper pressure plate 1 from being unable to fasten the photovoltaic panel 6. This improves the installation efficiency of maintenance personnel and eliminates the need for secondary installation.
