Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module technology, specifically a lightweight photovoltaic module encapsulation structure based on flexible glass. Background Technology

[0002] The lightweight photovoltaic module encapsulation structure based on flexible glass uses ultra-thin flexible glass as the front panel, typically with a thickness in the range of 50-100 micrometers. It features high light transmittance (>90%), flexibility, and impact resistance. Combined with lightweight solar cells (such as thin-film crystalline silicon cells), POE encapsulation film, and a composite material backsheet, it forms an integrated structure through encapsulation processes. This encapsulation structure reduces module weight by 30%-50% while maintaining high light transmittance and weather resistance. It is suitable for curved roofs, vehicle roofs, mobile energy devices, and other scenarios, and is particularly suitable for building-integrated photovoltaics (BIPV) and distributed photovoltaic projects, providing efficient power generation solutions for complex surfaces or lightweight requirements.

[0003] Existing photovoltaic module encapsulation mechanisms are not convenient for encapsulating and fixing photovoltaic panels, which increases the difficulty of encapsulation and reduces work efficiency. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a lightweight photovoltaic module packaging structure based on flexible glass, which effectively solves the problem that the existing photovoltaic module packaging mechanism is not convenient for packaging and fixing the photovoltaic panel, which increases the packaging difficulty and reduces work efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lightweight photovoltaic module encapsulation structure based on flexible glass, including a mounting frame, a photovoltaic panel placed inside the mounting frame, a connecting frame at the front of the mounting frame, flexible glass fixedly installed inside the connecting frame, insertion rods fixedly installed at each of the four corners on one side of the connecting frame, insertion holes opened at each of the four corners on the front side of the mounting frame, a sealing gasket fixedly installed on the front surface of the mounting frame, locking holes opened at the ends of the four insertion rods, and the four insertion rods respectively inserted into the four insertion holes, a protective shell fixedly installed at the rear of the mounting frame, a handwheel located in the middle of the bottom of the protective shell, a transmission component located at the top of the handwheel, locking rods at each of the four corners inside the protective shell, the transmission component being connected to the four locking rods, and when the handwheel rotates, power is output to the four locking rods through the transmission component, causing the four locking rods to engage with the four locking holes to limit the four insertion rods, thereby fixing the connecting frame.

[0006] Preferably, the transmission assembly includes a shaft with three bushings rotatably mounted on its surface. One side of each of the three bushings is fixedly connected to the interior of the protective shell. A driving bevel gear is fixedly mounted on the top of the shaft. A driven bevel gear is meshed with one side of the surface of the driving bevel gear. A rotating shaft is fixedly mounted in the middle of the driven bevel gear. Two bearings are rotatably mounted on the surface of the rotating shaft, and one side of each of the two bearings is fixedly connected to the interior of the protective shell.

[0007] Preferably, threaded rods are fixedly installed at both ends of the rotating shaft, threaded sleeves are threadedly connected to the surfaces of the two threaded rods, and pushing strips are fixedly installed at the ends of the two threaded sleeves that are far apart from each other. Rollers are tightly attached to the inclined surfaces of the two pushing strips at both ends. Rectangular rods are fixedly installed at one end of each of the four rollers, and rectangular sleeves are fitted on one end of the surface of each of the four rectangular rods. One side of each of the four rectangular sleeves is fixedly connected to the inside of the protective shell. Springs are fitted on the other end of each of the four rectangular rods. The two ends of each of the four springs are fixedly connected to the rectangular sleeves and the rollers, respectively. Moving blocks are fixedly installed at the ends of each of the four rectangular rods that are far apart from the rollers through connecting strips. One end of each of the four moving blocks is fixedly connected to the four locking rods.

[0008] Preferably, each of the threaded sleeves is fixedly mounted with a sliding sleeve, and each sliding sleeve has a sliding rod inserted inside, with both ends of the two sliding rods fixedly connected to the inside of the protective shell.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: During encapsulation, the operator inserts the four plugs on the connecting frame into the four holes on the mounting frame, so that the connecting frame fits against the mounting frame, and the photovoltaic panel is encapsulated and protected by the flexible glass and the sealing gasket; then the operator drives the shaft to rotate inside the two bushings by using the handwheel, and when the shaft rotates, it drives the driven bevel gear to rotate through the active bevel gear, and when the driven bevel gear rotates, it drives the rotating shaft to rotate inside the two bearings;

[0010] When the shaft rotates, it drives two threaded sleeves to move in opposite directions via two threaded rods. As the threaded sleeves move, they cause two sliding sleeves to slide along the surfaces of two sliding rods, increasing the stability of the threaded sleeves during movement. When the threaded sleeves move in opposite directions, they push four rollers through two pushing bars, thus smoothly driving four rectangular rods to move along the interior of four rectangular sleeves, while simultaneously compressing four springs. As the four rectangular rods move, they drive four moving blocks to move through four connecting bars. As the four moving blocks move, they cause four locking rods to engage with the interior of four locking holes, limiting the four insertion rods and thus fixing the connecting frame. This makes the photovoltaic module encapsulation mechanism easier to encapsulate and fix the photovoltaic panel, reducing the difficulty of encapsulation and improving work efficiency.

A transmission component is provided at the top of the handwheel 9. Each of the four corners inside the protective shell 7 has a locking rod 10. The transmission component is connected to the four locking rods 10. When the handwheel 9 is turned, the power is output to the four locking rods 10 through the transmission component, so that the four locking rods 10 are locked into the four locking holes 5 to limit the four insert rods 4, thereby fixing the connecting frame 2.

[0020] During encapsulation, the operator inserts the four insert rods 4 on the connecting frame 2 into the four insert holes 6 on the mounting frame 1, so that the connecting frame 2 fits against the mounting frame 1. The photovoltaic panel 8 is encapsulated and protected by the flexible glass 3 and the sealing gasket. Then, the operator drives the transmission component to rotate by the handwheel 9. When the transmission component rotates, it drives the four locking rods 10 to engage inside the four locking holes 5 to limit the four insert rods 4, thereby fixing the connecting frame 2. This makes the photovoltaic module encapsulation mechanism easy to encapsulate and fix the photovoltaic panel 8, reduces the difficulty of encapsulation, and improves work efficiency.

[0026] When the two threaded sleeves 18 move, they cause the two sliding sleeves 20 to slide along the surfaces of the two sliding rods 21, which increases the stability of the two threaded sleeves 18 when they move.
