Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation equipment, and in particular to a photovoltaic panel reinforcement device and a photovoltaic panel installation structure. Background Technology

[0002] Photovoltaic power generation is a renewable energy technology that utilizes solar energy. Based on the photovoltaic effect, it directly converts sunlight into electrical energy. Photovoltaic panels are the core component of a photovoltaic power generation system, mainly composed of solar cells, encapsulation materials, a backsheet, and a frame. Its working principle is based on the photoelectric effect. When sunlight shines on a solar cell, photons interact with electrons in the semiconductor material, causing electrons to jump from the valence band to the conduction band, forming electron-hole pairs. Under the influence of the electric field inside the semiconductor, electrons and holes migrate towards the positive and negative electrodes of the cell, respectively, thus forming an electric current and completing the conversion of light energy into electrical energy.

[0003] In a photovoltaic (PV) power station, solar panels are installed at a specific angle using brackets. This angle is precisely calculated to maximize sunlight capture and improve power generation efficiency. After a PV power station is put into operation, numerous problems and potential hazards are discovered during operation and maintenance, involving various equipment operation issues. Particularly concerning are components mounted on fixed brackets. After prolonged operation, the mounting bolts may loosen or fall off. Strong winds can easily cause PV panels to be blown off, resulting in torn panel frames, microcracks, shattered tempered glass, and damaged encapsulation. In severe cases, this can lead to the complete scrapping of the PV panel, affecting the safe and stable operation of the string and power generation, directly causing equipment damage and economic losses to the power station. Utility Model Content

[0004] This utility model addresses the problem that currently, photovoltaic panels are installed on photovoltaic panel brackets using bolt assemblies, which are prone to loosening after long-term operation and easily fall off and be damaged under external force. It provides a photovoltaic panel reinforcement assembly.

[0005] To address the aforementioned problems, this utility model employs a photovoltaic panel reinforcement device, comprising a fixing base and a pull rod. The fixing base includes a connecting pipe and a connecting seat for connecting the photovoltaic panel bracket. The pull rod includes an insertion rod and a pressure rod. The insertion rod is inserted into the inner hole of the connecting pipe, and a check valve is provided between the insertion rod and the connecting pipe. The pressure rod is located at the upper end of the insertion rod and extends to one side of the insertion rod. This solution designs a reinforcement component for additional reinforcement of the photovoltaic panel. Based on the connection structure between the photovoltaic panel bracket and the photovoltaic panel, this reinforcement device is installed between the two. The fixing base is installed on the photovoltaic panel bracket, and then the pull rod is inserted into the connecting pipe from top to bottom. The pressure rod presses down on the photovoltaic panel, and the check valve achieves fixation, preventing the pull rod assembly from being pulled out. This further securely presses the photovoltaic panel onto the photovoltaic panel bracket, preventing the photovoltaic panel from loosening. It can extend the loosening cycle of the component fixing bolts, reduce the vibration frequency and amplitude of the component due to strong winds after the bolts fall off, and reduce the probability of the component falling off.

[0006] As a preferred embodiment of a photovoltaic panel reinforcement device, the anti-reverse structure includes ratchet teeth disposed on the outer wall of the insertion rod, with the opening of the ratchet teeth facing upwards. An elastic plate is provided on the inner wall of the connecting tube, with its upper end fixedly connected to the connecting tube and its lower end protruding relative to the inner wall of the connecting tube, engaging with the ratchet teeth. After the pull rod is inserted into the connecting tube, the tight engagement between the elastic plate and the ratchet teeth provides a reliable one-way locking function. The elastic deformation of the elastic plate allows it to easily engage with the ratchet teeth while effectively preventing the insertion rod from being pulled upwards, greatly enhancing the stability of the reinforcement component and ensuring that the photovoltaic panel can be firmly pressed down in various environments.

[0007] As a preferred embodiment of a photovoltaic panel reinforcement device, the lower circumferential surface of the insertion rod is provided with a flat portion, and the lower part of the connecting tube is provided with a flattened section, the inner surface of which abuts against the flat portion. The cooperation between the flat portion and the flattened section effectively restricts the rotation of the insertion rod within the connecting tube, ensuring the insertion rod maintains a stable axial position under pressure. This not only improves the structural stability of the entire reinforcement device but also ensures that the pressure rod always accurately presses against the photovoltaic panel, achieving the best reinforcement effect and preventing the pressure rod from shifting due to insertion rod rotation.

[0008] As a preferred embodiment of a photovoltaic panel reinforcement device, the insertion rod has two flat portions, which are spaced 180 degrees apart circumferentially. The flattened section has a double-sided flattened structure, with its inner cavity having two planes that respectively abut against the two flat portions. The ratchet is located between the two flat portions, and the elastic sheet is located on the arc surface of the inner cavity of the flattened section. The precise fit between the two flat portions and the double-sided flattened section comprehensively restricts the rotational freedom of the insertion rod, ensuring the reinforcement device remains stable even under complex stress conditions.

[0009] As a preferred implementation of a photovoltaic panel reinforcement device, the lower part of the insertion rod is provided with multiple first connecting holes, which penetrate the insertion rod radially and are arranged along the length of the insertion rod. The connecting tube wall is provided with a second connecting hole, and a cotter pin is provided in both the second connecting hole and any of the first connecting holes. The second connecting hole is an elongated hole, and its diameter is larger than that of the first connecting hole. This design provides a second layer of security for the connection between the insertion rod and the connecting tube. By passing the cotter pin through the first and second connecting holes at different positions, different insertion depths can achieve reinforcement, adapting to different photovoltaic panel installation scenarios. The elongated hole design of the second connecting hole allows for fine-tuning of the insertion rod's position within a certain range, improving installation convenience and adaptability. Simultaneously, the use of the cotter pin further prevents the insertion rod from accidentally dislodging, enhancing the overall reliability of the reinforcement device.

[0010] As a preferred embodiment of a photovoltaic panel reinforcement device, the first side of the cotter pin is straight, and the second side of the cotter pin is wavy. The straight side facilitates insertion into the connection hole, while the wavy second side can fit tightly against the inner wall of the connection hole after insertion, increasing friction and preventing the cotter pin from loosening. This further improves the stability of the connection part of the reinforcement device and ensures that the photovoltaic panel remains firmly reinforced for a long time.

[0011] As a preferred embodiment of a photovoltaic panel reinforcement device, two pressure rods are provided, spaced 180 degrees apart. The photovoltaic panel reinforcement device is installed in the gap between two photovoltaic panels, which can simultaneously compress the photovoltaic panels on both sides, reducing the number of reinforcement devices required and lowering costs.

[0012] As a preferred embodiment of a photovoltaic panel reinforcement device, the pressure rod is arc-shaped, with one end connected to the insertion rod and the other end extending diagonally downwards. The arc-shaped pressure rod conforms to the shape of the photovoltaic panel's raised frame, securing the frame within the arc and increasing the contact area between the pressure rod and the photovoltaic panel. The downward-sloping extension of the pressure rod allows it to press more tightly against the photovoltaic panel during insertion, further enhancing the reinforcement effect and ensuring stable installation of the photovoltaic panel on the photovoltaic panel support under various environmental conditions.

[0013] As a preferred embodiment of a photovoltaic panel reinforcement device, the connecting seat is an upward-opening U-shaped plate, with one side of the U-shaped plate fixedly connected to the outer side of the connecting pipe. The U-shaped plate structure of the connecting seat facilitates connection with the photovoltaic panel bracket, and its upward-opening design facilitates installation. Components of the photovoltaic panel bracket can be directly inserted into the U-shaped groove to achieve a vertically pulling fixed structure. This connection method is simple and reliable, enabling rapid installation of the fixing seat onto the photovoltaic panel bracket, thus improving the installation efficiency of the photovoltaic panel reinforcement device.

[0014] On the other hand, this utility model also provides a photovoltaic panel mounting structure, including a photovoltaic panel bracket and a photovoltaic panel. The photovoltaic panel is mounted on the photovoltaic panel bracket by bolts. It also includes the aforementioned photovoltaic panel reinforcement device, which is located at the edge of the photovoltaic panel. The fixing seat is mounted on the photovoltaic panel bracket via the connecting seat, and the pressure rod presses against the upper surface of the photovoltaic panel. By applying the photovoltaic panel reinforcement device to the photovoltaic panel mounting structure, the stability and reliability of the entire photovoltaic system are further improved. Based on the original connection between the photovoltaic panel bracket and the photovoltaic panel, the addition of the reinforcement device increases the clamping force on the photovoltaic panel, effectively preventing the photovoltaic panel from loosening due to external forces, reducing the probability of the photovoltaic panel falling off, extending the service life of the photovoltaic system, and providing a strong guarantee for the stable operation of photovoltaic power generation.

[0015] As can be seen from the above technical solutions, the advantages of this utility model are as follows: Based on the original connection structure between the photovoltaic panel bracket and the photovoltaic panel, the additional reinforcement device effectively prevents the photovoltaic panel from loosening, extends the loosening cycle of the module fixing bolts, reduces the vibration frequency and amplitude caused by strong winds after the bolts fall off, and lowers the probability of the module falling off. In terms of specific structure, the elastic plate and ratchet in the anti-reverse structure provide reliable one-way locking, enhancing stability; the flat part of the insertion rod cooperates with the flattened section of the connecting tube to restrict the rotation of the insertion rod, ensuring accurate pressure application; the precise cooperation between the double-sided flat part and the double-sided flattened section provides all-around stability for the insertion rod; the multi-position connection holes and elongated hole design of the insertion rod and connecting tube provide additional safety and facilitate adjustment and installation; the specially shaped cotter pin prevents loosening; the double pressure rod spacing allows for simultaneous pressing of both photovoltaic panels, reducing costs; the arc-shaped pressure rod fits snugly against the photovoltaic panel frame, increasing the contact area, and the downward extension enhances the reinforcement effect; the U-shaped connector facilitates connection with the photovoltaic panel bracket, improving installation efficiency. Applying this photovoltaic panel reinforcement component to the photovoltaic panel installation structure further enhances the stability and reliability of the photovoltaic system, providing strong support for the stable operation of photovoltaic power generation.

[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0028] Example 1

[0029] In current photovoltaic panel installation structures, photovoltaic panel supports are typically welded from channel steel, and the photovoltaic panels are fixed to the channel steel supports by bolt assemblies. To address the issue of bolts easily loosening, this embodiment provides a photovoltaic panel reinforcement device, including a fixing base assembly 1 and a tie rod assembly 2.

[0030] like Figure 3 , 4 As shown, the fixing base part 1 includes a connecting pipe 101 and a connecting seat 102 for connecting the photovoltaic panel bracket. The connecting seat 102 is a U-shaped plate with its opening facing upwards. One side of the U-shaped plate is fixedly connected to the outer side of the connecting pipe 101. Since the photovoltaic panel bracket is a channel steel structure, the U-shaped plate with its opening facing upwards can hook onto the side plate of the channel steel. Figure 1 , 2As shown, the pull rod portion 2 includes an insertion rod 201 and a pressure rod 202. The insertion rod 201 is inserted into the inner hole of the connecting pipe 101. Two pressure rods 202 are provided, spaced 180 degrees apart. The pressure rods 202 are arc-shaped, with one end connected to the insertion rod 201 and the other end extending obliquely downward. A check valve structure is provided between the insertion rod 201 and the connecting pipe 101. The pressure rod 202 is located at the upper end of the insertion rod 201 and extends to one side of the insertion rod 201. In this embodiment, the anti-reverse structure includes a ratchet 3 disposed on the outer wall of the insertion rod 201, the opening of the ratchet 3 being upwardly oriented, an elastic piece 4 being disposed on the inner wall of the connecting tube 101, the upper end of the elastic piece 4 being fixedly connected to the connecting tube 101, the lower end of the elastic piece 4 protruding relative to the inner wall of the connecting tube 101, and the lower end of the elastic piece 4 being engaged in the ratchet 3.

[0031] Based on the above structure, and on the connection structure between the photovoltaic panel bracket and the photovoltaic panel, this reinforcement device is installed between the two. The fixing seat is hung on the photovoltaic panel bracket from bottom to top by the U-shaped plate, and then the pull rod is inserted into the connecting pipe from top to bottom. The pressure rod is pressed on the photovoltaic panel, and the pressure rod is fixed from top to bottom. The pull rod and the connecting pipe provide a reliable one-way locking function through the tight cooperation of the elastic plate and the ratchet. The elastic deformation of the elastic plate causes it to engage with the ratchet, effectively preventing the insertion rod from being pulled out upwards and preventing the pull rod from being pulled out, thereby further pressing the photovoltaic panel firmly onto the photovoltaic panel bracket.

[0032] Furthermore, the lower circumferential surface of the insertion rod 201 is provided with two flat portions 5 (or one), which can be obtained by milling. The lower part of the connecting tube 101 is provided with a flattened section 6, which squeezes the connecting tube 101 from both sides, thereby forming a racetrack-shaped cross-section of the inner hole of the flattened section 6, including two flat surfaces and two arc-shaped surfaces. The two flat surfaces of the inner surface of the flattened section 6 are respectively in contact with the two flat portions 5. The ratchet 3 is located between the two flat portions 5, and the elastic plate 4 is located on the arc surface of the inner cavity of the flattened section 6. In this way, the cooperation between the flat portions and the flattened section effectively restricts the rotation of the insertion rod in the connecting tube, thereby preventing the ratchet and the elastic plate from rotating and misaligning and loosening.

[0033] The lower part of the insertion rod 201 is provided with a plurality of first connecting holes 7, which penetrate the insertion rod 201 radially, and the plurality of first connecting holes 7 are arranged along the length direction of the insertion rod 201; the wall of the connecting tube 101 is provided with a second connecting hole 8, and a cotter pin 9 is provided in both the second connecting hole 8 and any of the first connecting holes 7, such as Figure 5As shown, the first side of the cotter pin 9 is a straight side, and the second side of the cotter pin 9 is wavy; the second connecting hole 8 is an oblong hole, and the diameter of the second connecting hole 8 is larger than the diameter of the first connecting hole 7. The cotter pin provides a second layer of security for the connection between the insertion rod and the connecting tube. By passing the cotter pin through the first connecting hole and the second connecting hole at different positions, different insertion depths can achieve connection reinforcement.

[0034] Example 2

[0035] This embodiment provides a photovoltaic panel mounting structure, including a photovoltaic panel bracket 11 and a photovoltaic panel 10. The photovoltaic panel 10 is mounted on the photovoltaic panel bracket 11 by bolts. It also includes the photovoltaic panel reinforcement device provided in Embodiment 1, such as... Figure 7 , 8 As shown, the photovoltaic panel reinforcement device is installed at the edge of the photovoltaic panel 10, the fixing seat part 1 is installed on the photovoltaic panel bracket 11 through the connecting seat 102, and the pressure rod 202 presses on the upper surface of the photovoltaic panel 10.

[0036] As can be seen from the above embodiments, the beneficial effects of this utility model are that, on the original connection structure between the photovoltaic panel bracket and the photovoltaic panel, the newly added reinforcement device can effectively prevent the photovoltaic panel from loosening. It can extend the loosening cycle of the component fixing bolts, and after the bolts fall off, reduce the vibration frequency and amplitude caused by strong winds, thus reducing the probability of the component falling off. From a specific structural perspective, the elastic plate and ratchet in the anti-reverse structure cooperate to achieve reliable one-way locking and improve stability; the flat part of the plug rod and the flattened section of the connecting tube work together to restrict the rotation of the plug rod and ensure precise pressure application of the pressure rod; the precise cooperation of the flat parts on both sides and the flattened sections on both sides provides all-round stability for the plug rod; the multi-position connection holes and the elongated hole design of the plug rod and the connecting tube provide additional safety protection and facilitate installation and adjustment; the specially shaped cotter pin can prevent loosening; the spaced double pressure rods can simultaneously press the photovoltaic panels on both sides, reducing costs; the arc-shaped pressure rod fits the photovoltaic panel frame, increasing the contact area, and its downwardly extending design enhances the reinforcement effect; the U-shaped connecting seat facilitates connection with the photovoltaic panel bracket and improves installation efficiency. Applying this photovoltaic panel reinforcement component to the photovoltaic panel installation structure further enhances the stability and reliability of the photovoltaic system, and strongly supports the stable operation of photovoltaic power generation.
