Description

Technical Field

[0001] This application relates to the field of photovoltaic module installation technology, specifically a photovoltaic module installation frame. Background Technology

[0002] Photovoltaic modules, also known as solar panels, are the core component of a solar power generation system. They are formed by connecting and tightly packaging multiple photovoltaic cells (cells) in series and parallel to create a single, indivisible photovoltaic cell assembly capable of providing direct current output.

[0003] Existing mounting frames typically involve directly abutting the photovoltaic modules against the mounting frame and then securing them together with bolts. While this method is relatively secure, it is extremely inconvenient to install and remove, and it also allows rainwater to seep in through the contact area between the mounting frame and the photovoltaic modules, thus affecting the stability and longevity of the installation. Utility Model Content

[0004] In view of this, the purpose of this utility model is to address the shortcomings of the prior art by proposing a photovoltaic module mounting frame to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a photovoltaic module mounting frame, including a mounting frame, a waterproof cotton block provided on the inner wall of the mounting frame, a socket movably inserted into the mounting frame, an adapter groove provided on the outer surface of the socket, a mounting base fixedly connected to the outer surface of the socket, an expansion sealing strip provided at one end of the outer surface of the socket near the mounting base, a photovoltaic panel fixedly connected to the mounting base, hook assemblies provided at both ends of the mounting base, and a limit mechanism provided on the outer surface of the mounting frame.

[0006] Preferably, the hook assembly includes fixing plates that are fixedly connected to both ends of the mounting base. Limiting hooks are fixedly connected to the outer surfaces of both sets of fixing plates. The hook assembly, in conjunction with the limiting mechanism, can stably limit the mounting base, thereby allowing the photovoltaic panel to be quickly installed and removed.

[0007] Preferably, the limiting mechanism includes fixed frames that are fixedly connected to both ends of the mounting frame. The outer surfaces of both sets of fixed frames are fixedly connected to frame shafts, and the outer surfaces of both sets of frame shafts are rotatably connected to hooks. The limiting mechanism can stably limit the hook assembly, thereby indirectly ensuring that the photovoltaic panel is in a stable installation state.

[0008] Preferably, the bottom of the fixing frame is fixedly connected to a bottom shaft, an outer spring is provided on the bottom shaft, and the top of the outer spring is fixedly connected to a limiting hook. The fixing frame is provided with a stop rod.

[0009] Preferably, a fixing cylinder is fixedly connected to the outer surface of the hook, a slip ring is slidably connected to the inner wall of the fixing cylinder, and a positioning rod is fixedly inserted through the inner side of the slip ring.

[0010] Preferably, an inner spring is fixedly sleeved on the outer surface of the positioning rod, an iron plate is provided at one end of the positioning rod near the mounting base, and a magnet is provided on the mounting base.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The photovoltaic module mounting frame, through the plug-in cooperation between the socket and the mounting frame, and the ingenious locking mechanism of the hook and the limiting hook, realizes the quick installation and disassembly of the photovoltaic panel. In addition, the expansion sealing strip expands when it comes into contact with water, tightly fitting the gap between the mounting frame and the mounting base, forming an effective waterproof barrier. This design not only enhances the sealing of the installation, but also improves the firmness of the connection, thereby protecting the inside of the mounting frame from water erosion and improving the installation stability of the photovoltaic module.

[0013] 2. The photovoltaic module mounting frame is designed to prevent accidental contact or scratching of the positioning rod and fixing cylinder, which could lead to incorrect adjustment of the hook position. Therefore, the attraction between the iron plate and the magnet is cleverly introduced to limit the hook position. Once the hook is stably engaged with the limiting hook, the positioning rod is released. Under the elastic reset action of the inner spring, the slip ring moves, causing the iron plate to insert into the magnet on the mounting base surface. This design effectively avoids the problem of loosening or falling off the installation due to accidental contact with the hook, thus improving the safety and reliability of the installation.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0020] Please see Figure 1-4 A photovoltaic module mounting frame includes a mounting frame 1. Waterproof cotton blocks 2 are provided on the inner wall of the mounting frame 1. The waterproof cotton blocks 2 serve two purposes: firstly, to guide the accurate insertion of the socket 3 into the fitting groove 4, and secondly, to provide waterproofing. A socket 3 is movably inserted into the mounting frame 1. The outer surface of the socket 3 has fitting grooves 4, the same number as the number of waterproof cotton blocks 2, with three sets in total. A mounting base 6 is fixedly connected to the outer surface of the socket 3. An expansion water-stop strip 5 is provided at one end of the outer surface of the socket 3 near the mounting base 6. The expansion water-stop strip 5 expands when exposed to water. A photovoltaic panel 7 is fixedly connected to the mounting base 6. Hook assemblies are provided at both ends of the mounting base 6. A limit mechanism is provided on the outer surface of the mounting frame 1.

[0021] With the above technical solution, when installing the photovoltaic panel 7, simply insert the socket 3 into the mounting frame 1. With the help of the hook mechanism and the limiting mechanism, the mounting base 6 can be stably limited, thus indirectly and quickly installing the photovoltaic panel 7. When the limiting mechanism no longer limits the hook mechanism, the photovoltaic panel 7 can be easily removed. The function of the expansion sealing strip 5 is to waterproof and reinforce the connection of the mounting base 6.

[0022] Specifically, the hook assembly includes fixing plates 8 that are fixedly connected to both ends of the mounting base 6, and limit hooks 9 are fixedly connected to the outer surfaces of both fixing plates 8.

[0023] Through the above technical solution, two sets of limiting hooks 9 and claws 12 are provided, which are symmetrically designed at both ends of the mounting frame 1 and the mounting base 6, and the claws 12 can just hook the limiting hooks 9 (that is, the limiting hooks 9 can be stuck on the inner arc surface of the claws 12).

[0024] Specifically, the limiting mechanism includes fixed frames 10 that are fixedly connected to both ends of the mounting frame 1. The outer surfaces of the two sets of fixed frames 10 are fixedly connected to frame shafts 11, and the outer surfaces of the two sets of frame shafts 11 are rotatably connected to hooks 12.

[0025] With the above technical solution, when the hook 12 rotates along the frame shaft 11, one end of its two ends will be raised and the other end will be pressed down, thereby pulling the outer spring 14 and deforming it.

[0026] Specifically, the bottom of the fixing frame 10 is fixedly connected to the bottom shaft 13, the bottom shaft 13 is provided with an outer spring 14, and the top of the outer spring 14 is fixedly connected to the hook 12. The fixing frame 10 is provided with a stop rod 15.

[0027] Through the above technical solution, the function of the stop lever 15 is to relatively limit the hook 12, so as to prevent the hook 12 from rotating too much along the frame shaft 11. At the same time, it is also to make the hook 12 stably contact the stop lever 15 after it is locked in the column limit hook 9.

[0028] Specifically, a fixed cylinder 16 is fixedly connected to the outer surface of the hook 12, a slip ring 17 is slidably connected to the inner wall of the fixed cylinder 16, and a positioning rod 18 is fixedly inserted through the inner side of the slip ring 17.

[0029] With the above technical solution, the positioning rod 18 passes through the fixed cylinder 16 and the hook 12. When the hook 12 stably hooks the limit hook 9, the positioning rod 18 is directly opposite the magnet 21 on the mounting base 6.

[0030] Specifically, an inner spring 19 is fixedly sleeved on the outer surface of the positioning rod 18, an iron plate 20 is provided at one end of the positioning rod 18 near the mounting base 6, and a magnet 21 is provided on the mounting base 6.

[0031] Through the above technical solution, the part of the mounting base 6 where the magnet 21 is set is designed as a circular groove, in which the magnet 21 is located, and the diameter of the circular groove is the same as the diameter of the circular iron piece 20.

[0032] Working principle: During the installation of this photovoltaic module, the socket 3 on the mounting base 6 must first be inserted into the mounting frame 1. During this process, the waterproof cotton block 2 will slide along the adapter groove 4 to guide the socket 3 to be inserted accurately until the expansion sealing strip 5 is stably attached between the mounting frame 1 and the mounting base 6. The waterproof cotton block 2 serves to prevent rainwater from entering the interior of the mounting frame 1. During this process, the fixing plates 8 and the limiting hooks 9 at both ends of the mounting base 6 will gradually move closer to the hook claws 12. At the same time, during the insertion of the socket 3, the positioning rod 18 needs to be pulled outward to allow the slip ring 1 to move. 7. While sliding along the inner wall of the fixed cylinder 16, the inner spring 19 is compressed. At this time, the fixed cylinder 16 is also moved by the positioning rod 18, causing the hook 12 to rotate along the frame shaft 11. The grooved end of the hook 12 will gradually press down, while the other end will slowly rise, stretching the outer spring 14 to deform it until the limit hook 9 abuts against the stop rod 15. Then, the hand is released. Under the elastic restoring action of the outer spring 14, it will pull the hook 12 to rotate along the frame shaft 11, thereby stably hooking the limit hook 9 through the hook 12. 9. A stable limit is established, allowing for the indirect and rapid installation of the photovoltaic panel 7. Considering that the positioning rod 18 and the fixing cylinder 16 might be accidentally bumped or scratched, potentially causing the hook 12 to be misaligned and thus releasing the stable limit on the limit hook 9, the positioning rod 18 can be released after the hook 12 stably hooks and pulls the limit hook 9. Under the elastic reset action of the inner spring 19, it can push the slip ring 17 to move, allowing the iron piece 20 to insert into the magnet 21 in the circular groove on the surface of the mounting base 6. Through the attraction effect of the magnet 21 on the iron piece 20, the hook 12 is secured. The limiting function prevents accidental contact with the hook 12. After the photovoltaic panel 7 is installed, when rainwater comes into contact with the expansion waterstop strip 5, the expansion waterstop strip 5 absorbs water and expands, thereby "pushing" the mounting base 6 and causing the mounting base 6 to tend to move outward. This further increases the pulling force of the hook 12 on the limiting hook 9, increasing the stability of the installation. At the same time, after the expansion waterstop strip 5 absorbs water and expands (after its volume increases), the connection between it and the mounting frame 1 and the mounting base 6 is tighter, making it more difficult for rainwater to penetrate into the mounting frame 1, thus achieving excellent waterproofing effect.
