Description

Technical Field

[0001] This utility model relates to the field of photovoltaic frame technology, specifically to an aluminum photovoltaic frame connection structure. Background Technology

[0002] In the field of photovoltaic (PV) power generation, PV frames, as a crucial component of PV modules, not only protect the PV panels but also serve to install and secure them. Aluminum PV frames are widely used in the PV industry due to their lightweight, corrosion resistance, and ease of processing. During the construction and installation of PV power plants, multiple PV modules need to be connected via frames to form a sizable PV array. However, traditional aluminum PV frame connection structures have several problems, affecting the overall performance and stability of the PV system.

[0003] Traditional connection structures rely on a relatively simple method, typically using mechanical fasteners such as bolts to fix adjacent frames together. While this method is simple and direct, during long-term use, photovoltaic modules are subject to vibration and deformation due to environmental factors such as wind and temperature changes. This can easily lead to bolt loosening, causing the connection between frames to become loose, affecting the installation accuracy and stability of the photovoltaic modules, and potentially even causing safety accidents. Moreover, bolt connections alone have limited effectiveness in fixing the frames. Under significant external forces, the frames are prone to relative displacement, reducing the overall structural strength of the photovoltaic array. Therefore, we need to propose an aluminum photovoltaic frame connection structure. Utility Model Content

[0004] The purpose of this utility model is to provide an aluminum photovoltaic frame connection structure that can solve the problem of weak connection in traditional connection structures, thereby addressing the issues raised in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

One end of the plug-in portion is fixedly connected to a guide portion to facilitate the insertion of the plug-in portion into the frame. A fixing bolt is provided between the bottom of the frame and the plug-in portion. A circular groove and a rectangular mounting groove are provided on the top of the plug-in portion. The top of the circular groove communicates with the interior of the rectangular mounting groove.

[0023] 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.

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] An aluminum photovoltaic frame connection structure includes:

[0026] Two sets of frame 1, with an angle iron component 2 set between the two sets of frame 1;

[0027] In an optional embodiment: the angle iron assembly 2 includes a connector 21, both ends of which are fixedly connected to a plug-in portion 22. One end of the plug-in portion 22 is fixedly connected to a guide portion 23, which facilitates the insertion of the plug-in portion 22 into the frame 1. A fixing bolt 28 is provided between the bottom of the frame 1 and the plug-in portion 22. A circular groove 24 and a rectangular mounting groove 25 are provided on the top of the plug-in portion 22. The top of the circular groove 24 communicates with the interior of the rectangular mounting groove 25. An auxiliary limiting mechanism 26 is installed inside the circular groove 24 and the rectangular mounting groove 25 to provide auxiliary limiting for the frame 1.

[0028] It should be noted that the connector 21 is the main frame of the angle iron assembly 2, with an L-shaped structure (to accommodate the right-angle connection requirements of two sets of frame 1). Its two ends are fixedly connected to the insertion part 22 by welding or integral molding to ensure connection strength and prevent the insertion part 22 from detaching from the connector 21 during use. The external dimensions of the insertion part 22 are precisely matched to the internal cavity dimensions of the frame 1, and its length must provide sufficient connection depth after insertion into the frame 1 to ensure connection stability. The guide part 23 adopts a conical or arc-shaped structure design with a smooth surface. When the insertion part 22 is inserted into the frame 1, it effectively reduces the frictional resistance between the two and also serves as a guide and positioning element, preventing damage to the frame 1 or the insertion part 22 due to misalignment, thus improving installation efficiency. The fixing bolts 28 are made of stainless steel, possessing good rust resistance. Their specifications need to be determined according to... Based on the thickness and load-bearing requirements of the frame 1 and the plug-in part 22, threaded holes are made at the bottom of the frame 1 and the corresponding position of the plug-in part 22. The fixing bolts 28 are screwed into the threaded holes, which can further enhance the connection between the frame 1 and the plug-in part 22 and prevent relative displacement between the two during use. The diameter of the circular groove 24 is slightly larger than the outer diameter of the spring 262 and the steel ball seat 263, providing sufficient space for the movement of the auxiliary limiting mechanism 26. The size of the rectangular mounting groove 25 matches the size of the mounting plate 261, ensuring that the mounting plate 261 can be stably installed in the rectangular mounting groove 25. The rectangular structure can prevent the mounting plate 261 from rotating in the groove, ensuring the working stability of the auxiliary limiting mechanism 26. The circular groove 24 is connected to the rectangular mounting groove 25, so that each component of the auxiliary limiting mechanism 26 can be installed in the corresponding groove, and at the same time, the collaborative work between the components can be realized.

[0029] When installing the angle iron assembly 2, the insertion part 22 is slowly inserted into the frame 1 by the guide part 23 until the insertion part 22 is fully in contact with the inner wall of the frame 1. After insertion, the fixing bolt 28 is screwed into the threaded hole at the bottom of the frame 1 corresponding to the insertion part 22, so as to initially realize the fixed connection between the frame 1 and the angle iron assembly 2.

[0030] In an optional embodiment: the auxiliary limiting mechanism 26 includes a mounting plate 261, a spring 262 is fixedly mounted on the bottom of the mounting plate 261, a steel ball seat 263 is fixedly mounted on the bottom of the spring 262, a snap-fit ​​steel ball 264 is fixedly mounted on the bottom of the steel ball seat 263, and the bottom of the snap-fit ​​steel ball 264 passes through the insertion part 22 and snaps onto the bottom of the frame 1.

[0031] It should be noted that the mounting plate 261 is made of metal sheet with a high degree of surface flatness. The bottom is welded to the spring 262 to ensure that the spring 262 can be stably installed on the mounting plate 261. The spring 262 is a metal spring with good elastic recovery performance, and its elastic coefficient needs to be determined according to the limiting requirements of the auxiliary limiting mechanism 26. In its natural state, the spring 262 is in a slightly compressed state, providing continuous downward pressure to the ball bearing seat 263 and the locking ball 264, ensuring that the locking ball 264 can be tightly locked to the bottom of the frame 1. The ball bearing seat 263 has a cylindrical structure, and its bottom has a hemispherical groove adapted to the locking ball 264. The locking ball 264 is secured by an interference fit. The ball 264 is fixed in the groove at the bottom of the ball seat 263 by means of bonding or welding, ensuring that the ball 264 will not fall off the ball seat 263. At the same time, the outer diameter of the ball seat 263 is adapted to the inner diameter of the circular groove 24, allowing it to slide up and down in the circular groove 24, providing guidance for the extension and retraction of the ball 264. The ball 264 is made of high-strength wear-resistant metal material, and its surface is hardened, resulting in high hardness. It can withstand the extrusion force between the frame 1 and the insertion part 22. At the same time, its spherical structure helps to reduce frictional resistance during the snapping and disengaging process. A circular through hole is opened at the bottom of the insertion part 22 corresponding to the position of the ball 264, which enables the ball 264 to extend and retract within the through hole.

[0032] As the insertion part 22 is inserted into the frame 1, the bottom of the frame 1 exerts an upward squeezing force on the locking steel ball 264, causing the locking steel ball 264 to move upward. This, in turn, pushes the steel ball seat 263 upward to compress the spring 262, at which time the spring 262 stores elastic potential energy. When the insertion part 22 is fully inserted and the locking steel ball 264 moves to the slot 11 at the bottom of the frame 1, the spring 262 releases its elastic potential energy, pushing the steel ball seat 263 and the locking steel ball 264 downward, so that the bottom of the locking steel ball 264 is locked in the slot 11. This achieves the auxiliary limiting function of the auxiliary limiting mechanism 26 on the frame 1, further preventing relative displacement between the frame 1 and the insertion part 22, and forming a double fixing effect in conjunction with the fixing bolt 28.

[0033] In an optional embodiment: the mounting plate 261 is mounted inside the rectangular mounting groove 25, the spring 262 and the steel ball seat 263 are located inside the circular groove 24, and two sets of internal hex bolts 27 are installed between the mounting plate 261 and the inner bottom of the rectangular mounting groove 25.

[0034] It should be noted that the depth of the rectangular mounting groove 25 is slightly greater than the thickness of the mounting plate 261. This ensures that after the mounting plate 261 is installed in the rectangular mounting groove 25, the top of the mounting plate 261 will not exceed the top surface of the insertion part 22, thus avoiding affecting the normal insertion of the insertion part 22 and the frame 1. The length of the spring 262 must be sufficient so that, in its natural state, the bottom of the ball bearing seat 263 can contact the inner bottom of the circular groove 24. At the same time, in the compressed state, the spring 262 will not be damaged due to excessive compression, ensuring that the spring 262 can work stably for a long time. Two sets of internal hex bolts 27 are symmetrically distributed on the mounting plate 261. The specifications of both sides need to be determined according to the thickness of the mounting plate 261 and the fixing requirements. By opening threaded holes at corresponding positions on the inner bottom of the mounting plate 261 and the rectangular mounting groove 25, the hexagon socket bolts 27 can be screwed into the threaded holes to firmly fix the mounting plate 261 in the rectangular mounting groove 25, preventing the mounting plate 261 from loosening or shifting during use, thereby ensuring the working stability of the entire auxiliary limiting mechanism 26. The head of the hexagon socket bolts 27 can be embedded in the surface of the mounting plate 261 (the mounting plate 261 has countersunk holes at corresponding positions), avoiding the bolt head protruding and affecting the installation and use of other components.

[0035] When assembling the auxiliary limiting mechanism 26, first fix the top of the spring 262 to the bottom of the mounting plate 261, then fix the steel ball seat 263 to the bottom of the spring 262, and then fix the snap-fit ​​steel ball 264 to the bottom of the steel ball seat 263, thus completing the pre-assembly of the components of the auxiliary limiting mechanism 26; then place the pre-assembled auxiliary limiting mechanism 26 into the rectangular mounting groove 25 and the circular groove 24 at the top of the insertion part 22, so that the mounting plate 261 is located in the rectangular mounting groove 25, and the spring 262 and the steel ball seat 263 are located in the circular groove 24; finally, use an Allen wrench to screw the two sets of Allen bolts 27 into the threaded holes at the bottom of the mounting plate 261 and the rectangular mounting groove 25 respectively, to firmly fix the mounting plate 261, thus completing the installation of the auxiliary limiting mechanism 26 on the insertion part 22, and preparing for the subsequent cooperation with the frame 1.

[0036] In an optional embodiment: a telescopic rod 265 is fixedly mounted inside a spring 262 on a mounting plate 261, the bottom of which is fixedly mounted to the top of a ball bearing seat 263.

[0037] It should be noted that the telescopic rod 265 adopts a multi-section metal telescopic structure, with its outer diameter slightly smaller than the inner diameter of the spring 262, allowing it to be nested inside the spring 262. Furthermore, the telescopic length of the telescopic rod 265 is matched to the compression and extension lengths of the spring 262, ensuring that the telescopic rod 265 can extend and retract synchronously during the extension and retraction of the spring 262 without hindering its movement. The top of the telescopic rod 265 is fixed to the mounting plate 261 by welding or bolts, and the bottom is fixed to the top of the ball bearing seat 263 in the same way, ensuring a stable connection between the telescopic rod 265, the mounting plate 261, and the ball bearing seat 263. The main function of the telescopic rod 265 is to prevent the spring 262 from shifting laterally or twisting during the extension and retraction process, ensuring that the spring 262 always extends and retracts in the axial direction. This ensures that the steel ball seat 263 and the locking steel ball 264 can always move in the axial direction of the circular groove 24, avoiding the locking steel ball 264 from failing to accurately engage in the slot 11 due to spring offset, thus affecting the limiting effect of the auxiliary limiting mechanism 26. At the same time, the telescopic rod 265 can also enhance the overall rigidity of the auxiliary limiting mechanism 26 to a certain extent, preventing fatigue damage to the spring 262 after long-term stress and extending the service life of the auxiliary limiting mechanism 26.

[0038] In an optional embodiment: the bottom of the frame 1 is provided with a slot 11 corresponding to the snap-fit ​​steel ball 264, and the bottom of the snap-fit ​​steel ball 264 is snapped into the inside of the slot 11.

[0039] It should be noted that the diameter of the slot 11 is compatible with the diameter of the snap-fit ​​steel ball 264, ensuring that the bottom of the snap-fit ​​steel ball 264 can fit tightly in the slot 11 to form a stable snap-fit ​​structure. The opening position of the slot 11 at the bottom of the frame 1 must correspond precisely with the position of the snap-fit ​​steel ball 264 on the insertion part 22 to ensure that when the insertion part 22 is inserted into the frame 1, the snap-fit ​​steel ball 264 can move to the position of the slot 11 and achieve snap-fit. If the position is deviated, the auxiliary limiting mechanism 26 will not function.

[0040] During the insertion of the connector 22 into the frame 1, when the locking steel ball 264 is aligned with the slot 11, the elastic force of the spring 262 pushes the locking steel ball 264 into the slot 11. At this time, the operator can judge whether the locking is in place by touch or hearing (the slight sound of the spring returning to its original position), and then confirm that the connector 22 has been inserted into the correct position. Then the installation of the fixing bolt 28 can be carried out to achieve complete fixation of the frame 1 and the angle iron assembly 2.

[0041] In an optional embodiment: both sides of the plug portion 22 are provided with elongated grooves 29, and extrusion strips 210 are fixedly installed inside the elongated grooves 29. The extrusion strips 210 are in elastic extrusion contact with the inner walls of the frame 1.

[0042] It should be noted that the elongated groove 29 is opened along the length of the insertion part 22. The width and depth need to be determined according to the size of the extrusion strip 210 to ensure that the extrusion strip 210 can be tightly installed in the elongated groove 29 and will not fall out of the elongated groove 29 during use. The extrusion strip 210 is made of elastic rubber or silicone, which has good elasticity and wear resistance, and also has certain aging resistance and high and low temperature resistance, so as to meet the needs of photovoltaic frames in complex outdoor environments. When the insertion part 22 is inserted into the frame 1, the extrusion strip 210 can form elastic extrusion contact with both sides of the inner wall of the frame 1, generating a certain extrusion force. This elastic extrusion contact can fill the gap between the insertion part 22 and the inner wall of the frame 1, improve the sealing of the connection structure, and increase the friction between the insertion part 22 and the frame 1, further preventing relative displacement between the two and enhancing the connection stability. At the same time, the elastic contact can also buffer the impact of external vibration on the connection structure to a certain extent, improving the vibration resistance of the entire photovoltaic frame.

[0043] Before the insertion part 22 is inserted into the frame 1, the extrusion strip 210 is first fixedly installed in the long grooves 29 on both sides of the insertion part 22 to ensure that the extrusion strip 210 is installed firmly and in the correct position. When the insertion part 22 is inserted into the frame 1 under the guidance of the guide part 23, the extrusion strip 210 gradually contacts and extrudes the inner wall of the frame 1. As the insertion part 22 continues to be inserted, the degree of extrusion gradually increases until the insertion part 22 is inserted in place. At this time, the extrusion strip 210 is in a stable elastic extrusion state and fits tightly against the inner wall of the frame 1 to achieve sealing and auxiliary anti-slip function. Together with the fixing bolt 28 and the auxiliary limiting mechanism 26, a triple guarantee is formed to ensure that the connection between the frame 1 and the angle iron assembly 2 is more firm and reliable.

[0044] In an optional embodiment, a sealing gasket 211 is fixedly installed on the outer wall of the connection between the plug portion 22 and the connector 21, and one side of the sealing gasket 211 abuts against one end of the frame 1.

[0045] It should be noted that the sealing gasket 211 is made of an elastic sealing material (such as rubber, silicone, etc.), and its shape is adapted to the shape of the outer wall of the connection between the plug part 22 and the connector 21 to ensure that it can completely cover the gap at the connection. The thickness of the sealing gasket 211 needs to be moderate. The sealing gasket 211 is installed on the outer wall of the connection between the plug part 22 and the connector 21 by adhesive bonding to ensure that the installation is firm and will not fall off or shift during use. When the plug part 22 is inserted into the frame 1 in place, one side of the sealing gasket 211 tightly abuts against one end of the frame 1, which can effectively prevent rainwater, dust, sand and other impurities from entering the interior of the frame 1 from the end of the frame 1 and the connection between the plug part 22 and the connector 21, and prevent internal components such as the fixing bolt 28 and the auxiliary limiting mechanism 26 from being corroded.

[0046] Working principle: When using this utility model, first determine the relative installation positions of the two sets of aluminum alloy frames 1, and place the angle iron assembly 2, which consists of connector 21, plug-in part 22, etc., between the two sets of frames 1 to prepare for subsequent connection. The frame 1 provides support, and the angle iron assembly 2 acts as a connecting bridge. With the help of the guide part 23 at the end of the plug-in part 22 (to reduce friction and guide positioning), the plug-in part 22 is slowly inserted into the inside of the frame 1 until it fits against the inner wall of the frame 1. Then, stainless steel fixing bolts 28 are screwed into the threaded holes at the bottom of the frame 1 corresponding to the plug-in part 22 to initially lock the positions of the two.

[0047] During the insertion process, the bottom of the frame 1 presses and clamps the steel ball 264, causing it to move the steel ball seat 263 upward to compress the spring 262 (the spring stores elastic potential energy); when the insertion part 22 is inserted into place, the clamping steel ball 264 aligns with the bottom slot 11 of the frame 1, the spring releases its potential energy, and pushes the steel ball seat 263 and the clamping steel ball 264 downward, so that the clamping steel ball 264 is clamped into the slot 11, and double fixation is achieved with the fixing bolt 28. During this process, the telescopic rod 265 prevents the spring from shifting laterally and ensures that the steel ball is accurately clamped.

[0048] Before insertion, the extrusion strip 210 is installed in the long grooves 29 on both sides of the insertion part 22. After insertion into the frame 1, the extrusion strip 210 is elastically squeezed against the inner wall of the frame 1 to fill the gap (prevent impurities from entering) and increase friction (prevent relative sliding). At the same time, the sealing gasket 211 at the connection between the insertion part 22 and the connector 21 abuts against the end of the frame 1 to prevent external impurities from entering from the end gap. The double seal ensures that the internal components are not corroded.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
