Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel fixing technology, and in particular to a photovoltaic panel connection device that is easy to install and disassemble. Background Technology

[0002] Photovoltaic power generation, as an important component of clean energy, has been widely used in recent years. As the core component of a photovoltaic power generation system, the ease and reliability of photovoltaic panels' installation and connection directly affect the overall performance and operation and maintenance efficiency of the system. Currently, most common photovoltaic panel connection methods on the market use direct bolt fixing or simple snap-fit ​​structures, which suffer from problems such as complex installation, inconvenient disassembly, and poor adaptability.

[0003] Traditional bolt fixing methods require specialized tools for installation, which is cumbersome and time-consuming. This low installation efficiency is a significant factor hindering project progress, especially in large-scale photovoltaic power plant construction. Furthermore, bolted connections are prone to corrosion and loosening in long-term outdoor environments, increasing the difficulty and cost of later maintenance.

[0004] While existing snap-fit ​​connection devices simplify the installation process to some extent, they often suffer from defects such as unreasonable structural design, insufficient locking force, and poor seismic performance. Especially under severe weather conditions, such as strong winds, rain, and snow, the reliability of the connection device directly affects the safe operation of the entire photovoltaic system. Utility Model Content

[0005] Based on this, it is necessary to provide a photovoltaic panel connection device that is easy to install and disassemble, addressing the aforementioned technical problems. The device includes a pressure plate that can slide along a sliding rod on a base, and an actuator that drives the pressure plate to move up and down. When using the device, the actuator can be activated to drive the pressure plate to press down, thereby simultaneously squeezing the batch extraction columns located on the base into the sample tubes. This saves manpower, improves extraction efficiency, and ensures a more uniform column throughput and better reproducibility.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A photovoltaic panel connection device that is easy to install and remove includes:

[0008] The base has through holes at its four corners, and four bearing seats are arranged close to the through holes on the top of the base.

[0009] A fixing clamp, which is inserted into the through hole, is used to fix the base onto the photovoltaic panel bracket;

[0010] The assembly buckle is rotatably connected within two symmetrical bearings and can be flipped relative to the base to lock or unlock.

[0011] The mounting bracket includes a plate structure and a block structure. The block structure has a snap-fit ​​groove on its side wall and positioning holes at the four corners of the plate structure.

[0012] The fixing bolts pass through the positioning holes on the side wall of the plate structure, and the assembly bracket is connected to the photovoltaic panel by the fixing bolts;

[0013] A locking mechanism, located in the middle of the base, is used to restrict the mounting buckle from flipping up or down.

[0014] Furthermore, the fixing clamp includes a rectangular rod and threaded posts fixedly connected to both ends of the rectangular rod. One end of the threaded post that protrudes through the through hole is threadedly connected to a fixing nut. The entire fixing clamp can be fixed to the photovoltaic panel bracket by connecting the fixing nut to the threaded post. The fixing spacing can also be adjusted by the locking position of the fixing nut, which is suitable for different photovoltaic panel brackets. Furthermore, the corresponding rectangular rod can be replaced for different photovoltaic panel brackets to facilitate the fixing purpose.

[0015] Furthermore, the assembly buckle includes a shaft portion, which is rotatably connected to a bearing seat via a rotating shaft. The sidewalls of the shaft portion have a pressing part, a fastening tooth, and a braking part, respectively. The braking part abuts against the locking mechanism. A torsion spring is fitted on the outer wall of the rotating shaft. The two ends of the torsion spring are respectively engaged and fixed with the pressing part and the base. The torsion spring can provide elastic potential energy for the pressing part to flip and reset upwards, thereby facilitating automatic reset after the pressing force is lost. The fastening tooth can engage with the locking groove on the block structure, thereby fixing the block structure.

[0016] The assembly bracket and assembly buckle are connected to the photovoltaic panel bracket and photovoltaic panel respectively. The separate structure allows for quick assembly, achieving the purpose of pre-installation and direct assembly, and improving the convenience of later maintenance.

[0017] Furthermore, the pressing part is located on the outside of the base, the snap-fit ​​teeth include a vertical part and a horizontal part, and the horizontal part and the vertical part form a right angle structure. The top of the horizontal part has a first inclined surface, and the bottom of the block structure has a second inclined surface that cooperates with the first inclined surface. The first inclined surface can move outward after being subjected to a squeezing force, so that the block structure can be effectively docked and fixed with the snap-fit ​​teeth.

[0018] Furthermore, a vertical shaft is fixedly connected to the middle of the base, and the locking mechanism includes a top column fixedly connected to the top of the vertical shaft. When the block structure moves to the position of the top column, it is in a restricted state and is engaged with the assembly buckle. The top column can support the block structure to prevent the block structure from being suspended in the air, thereby overcoming the problem of external pressure overload affecting the overall stability of the assembly.

[0019] Furthermore, the locking mechanism also includes a turntable rotatably connected to the side wall of the vertical shaft. A locking block is fixedly connected to the side wall of the turntable. When the locking block moves to the lower part of the braking part, it restricts the assembly buckle from flipping downward. When the locking block moves to the upper part of the braking part, it restricts the assembly buckle from flipping upward. When the locking block rotates counterclockwise to one side, it can disengage from the braking part, thereby facilitating the free rotation of the assembly buckle. Conversely, when the locking block rotates clockwise to the other side, it can be located above or below the braking part.

[0020] Furthermore, the turntable has a rotating handle on its side wall, which extends to the outside of the base, and the rotating handle facilitates the rotation of the turntable and the locking block.

[0021] Furthermore, there are two rotating handles and two locking blocks. The two rotating handles and two locking blocks are symmetrically arranged on the side wall of the turntable with the vertical axis as the central axis. The two rotating handles make it convenient to operate from either side.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] Improved ease of installation: A unique design combining mounting clips and mounting brackets enables rapid installation and removal of photovoltaic panels. Operators can easily secure the panels with simple pressing and rotation, significantly reducing installation time and improving work efficiency.

[0024] Enhanced structural reliability: The design employs a dual locking mechanism, including a mechanical locking system with mounting clips and an additional fixing mechanism, ensuring the stability and reliability of the connection device under various environmental conditions. Especially under harsh conditions such as strong winds and vibrations, it effectively prevents photovoltaic panels from detaching.

[0025] High versatility and adaptability: The fixing clamps feature an adjustable design, using a combination of rectangular rods and threaded posts to accommodate photovoltaic panel brackets of different specifications. This design increases the applicability of the device, reduces the types of accessories, and lowers inventory costs.

[0026] Improved ease of maintenance: The modular design allows each component to be replaced independently. When a component is damaged, only that component needs to be replaced, without the need to replace the entire unit, which greatly reduces maintenance costs and time. Attached Figure Description

[0041] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0042] Example 1

[0043] Please refer to Figure 1-7 A photovoltaic panel connection device that is easy to install and remove includes:

[0044] The base 1 has through holes 11 at its four corners and four bearing seats 12 arranged near the through holes 11 on its top.

[0045] The fixing clamp 2 is inserted into the through hole 11 to fix the base 1 onto the photovoltaic panel bracket 13;

[0046] The assembly buckle 3 is rotatably connected within two symmetrical bearing seats 12 and can be flipped relative to the base 1 to be locked or unlocked.

[0047] The mounting bracket 4 includes a plate structure 41 and a block structure 42. A snap-fit ​​groove 43 is provided on the side wall of the block structure 42, and positioning holes are provided at the four corners of the plate structure 41.

All key components are made of corrosion-resistant and high-strength materials and undergo special surface treatment, enabling them to adapt to harsh outdoor environments and extending the service life of the device.

[0051] Example 2

[0052] The photovoltaic panel connection device for easy installation and disassembly provided in Embodiment 1 is further optimized. Specifically, the fixing clamp 2 includes a rectangular rod 21 and threaded posts 22 fixedly connected to both ends of the rectangular rod 21. One end of the threaded post 22 that passes through the through hole 11 is threadedly connected to a fixing nut 23. The entire fixing clamp 2 can be fixed to the photovoltaic panel bracket 13 by connecting the fixing nut 23 to the threaded post 22. The fixing distance can also be adjusted by the locking position of the fixing nut 23 to suit different photovoltaic panel brackets 13. Furthermore, the corresponding rectangular rod 21 can be replaced for different photovoltaic panel brackets 13 to facilitate the fixing purpose.

[0053] The fixing clamp 2 features an adjustable design, which allows for adaptation to photovoltaic panel brackets of different sizes by adjusting the position of the fixing nut 23. This provides excellent versatility and can accommodate photovoltaic panel brackets of various specifications. This design increases the applicability of the device, reduces the types of accessories, and lowers inventory costs.

[0054] Example 3

[0055] The photovoltaic panel connection device provided in Embodiment 1 or 2 for easy installation and disassembly is further optimized. The assembly buckle (3) is the core component for achieving rapid installation. The assembly buckle 3 includes a shaft 31, which is rotatably connected to the bearing 12 via a rotating shaft 32. The side wall of the shaft 31 has a pressing part 33, a fastening tooth 34 and a braking part 35. The braking part 35 abuts against the locking mechanism 6. A torsion spring is fitted on the outer wall of the rotating shaft 32. The two ends of the torsion spring are respectively engaged and fixed with the pressing part 33 and the base 1. The torsion spring can provide the pressing part 33 with elastic potential energy to flip and reset upward, so as to facilitate automatic reset after the pressing force is lost. The fastening tooth 34 can engage with the fastening groove 43 on the block structure 42, thereby fixing the block structure 42.

[0056] The assembly bracket 4 and the assembly buckle 3 are connected to the photovoltaic panel bracket 13 and the photovoltaic panel 14 respectively. They adopt a split structure, which can be quickly assembled, realize the purpose of pre-installation and direct assembly, and improve the convenience of later maintenance.

[0057] The pressing part 33 is located on the outer side of the base 1. The engaging tooth 34 includes a vertical part and a horizontal part, and the horizontal part and the vertical part form a right-angle structure. The top of the horizontal part has a first inclined surface, and the bottom of the block structure 42 has a second inclined surface that cooperates with the first inclined surface. The first inclined surface can move outward after being subjected to pressure, so that the block structure 42 can be effectively engaged and fixed with the engaging tooth 34. The bottom of the block structure is provided with the second inclined surface, which cooperates with the first inclined surface on the engaging tooth to ensure smooth guidance and engagement during installation.

[0058] Example 4

[0059] The photovoltaic panel connection device provided in Embodiment 3, which is easy to install and disassemble, is further optimized. A vertical shaft 15 is fixedly connected to the middle of the base 1. The locking mechanism 6 includes a top column 61 fixedly connected to the top of the vertical shaft 15. When the block structure 42 moves to the position of the top column 61, it is in a restricted state and is engaged with the assembly buckle 3. The top column 61 can support the block structure 42 to avoid the block structure 42 being suspended in the air, thereby overcoming the problem of external pressure overload affecting the overall stability of the assembly.

[0060] The locking mechanism 6 also includes a turntable 62 rotatably connected to the side wall of the vertical shaft 15. A locking block 63 is fixedly connected to the side wall of the turntable 62. When the locking block 63 moves to the lower part of the braking part 35, it restricts the mounting buckle 3 from flipping downward. When the locking block 63 moves to the upper part of the braking part 35, it restricts the mounting buckle 3 from flipping upward. When the locking block 63 rotates counterclockwise to one side, it can disengage from the braking part 35, thereby facilitating the free rotation of the mounting buckle 3. Conversely, when the locking block 63 rotates clockwise to the other side, it can be located above or below the braking part 35.

[0061] The side wall of the turntable 62 has a rotating handle 64 that extends to the outside of the base 1. The rotating handle 64 facilitates the rotation of the turntable 62 and the locking block 63.

[0062] There are two rotating handles 64 and two locking blocks 63. The two rotating handles 64 and the two locking blocks 63 are symmetrically arranged on the side wall of the turntable 62 with the vertical axis 15 as the central axis. The two rotating handles 64 can be operated from either side.

[0063] The photovoltaic panel connection device provided by this utility model, which facilitates installation and disassembly, is used as follows: In the actual installation process, the base 1 is first fixed to the photovoltaic panel bracket 13 by the threaded connection between the fixing nut 23 and the threaded post 22. Then, the mounting bracket 4 is installed on the photovoltaic panel 14 by the fixing bolt 5. The block structure 42 at the bottom of the photovoltaic panel 14 is directly aligned with the base 1. When inserted, the block structure 42 abuts against the locking teeth 34, causing the locking teeth 34 to unfold outward. After insertion, under the action of the torsion spring, the locking teeth 34 automatically close and lock the block structure 42, automatically completing the installation. When disassembly is required, the pressing part 33 is pushed down to release the locking teeth 34 from the block structure 42, thereby removing the restriction and disassembling the photovoltaic panel 14. Finally, by rotating the handle 64 of the locking mechanism 6, the locking block 63 is positioned in the corresponding position of the braking part 35, completing the locking process. Specifically, when the locking block 63 moves below the braking part 35, it restricts the mounting clip 3 from flipping downwards; when the locking block 63 moves above the braking part 35, it restricts the mounting clip 3 from flipping upwards. This device not only improves installation efficiency and reduces labor costs, but also ensures connection reliability through a multi-locking design, enabling it to adapt to various harsh environmental conditions and providing a strong guarantee for the safe and stable operation of the photovoltaic power generation system.
