Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and in particular to a lightweight photovoltaic component. Background Art

[0002] Among all solar cells, silicon solar cells are one of the most widely commercialized solar cells. This is because silicon materials have extremely rich reserves in the earth's crust. At the same time, silicon solar cells have excellent electrical and mechanical properties compared to other types of solar cells. Photovoltaic modules can be divided into double-glass modules and single-glass modules. The two have similar structures, including the cover plate, the first packaging film, the cell layer, the second packaging film and the back plate from the front to the back. Among them, the cover plate and back plate of the double-glass module are both transparent glass; while the cover plate of the single-glass module is transparent glass, and the back plate is a flexible plate made of polymer materials.

[0003] The existing Chinese patent document CN201520029303.6 discloses a photovoltaic module frame, including: a long frame and a short frame, wherein the long frame is clamped with one end of an unframed photovoltaic module, and the short frame is clamped with the side of the unframed photovoltaic module. In addition, the utility model also discloses a photovoltaic module, including the photovoltaic module frame as described above. The photovoltaic module frame and the photovoltaic module adopt an embedded structure, and the unframed photovoltaic module is clamped with the long frame and the short frame. When framing the unframed photovoltaic module, there is no need to use frame corner code fixing and pre-riveting process, which simplifies the framing process of the unframed photovoltaic module, reduces the packaging cost of the photovoltaic module, and avoids the problems of photovoltaic module frame misalignment, drop and too large gap when the photovoltaic module is packaged.

[0004] However, the above patent has certain defects when used. Since most photovoltaic modules are installed on the roof, the brackets need to be prepared in advance. This method may have high requirements on the site and requires a large flat ground. It is extremely inconvenient when the bracket needs to be adjusted on the roof.

[0005] To this end, a lightweight photovoltaic module is proposed here to solve the above-mentioned problems. Utility Model Content

It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] The utility model is further described below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 5 As shown, a lightweight photovoltaic assembly 2 comprises a frame 1 and a photovoltaic assembly 2, wherein the photovoltaic assembly 2 is fixed inside the frame 1, and side hinge seats 9 are respectively provided at the bottom sides of the frame 1, wherein the frame 1 and the side hinge seats 9 are hingedly connected, and a bracket 5 is provided at the bottom of the side hinge seats 9;

[0026] A reinforcing rod 7 is provided between the brackets 5, and an adjusting device 6 is provided on the reinforcing rod 7. One end of the adjusting device 6 is fixed to the middle of the reinforcing rod 7. The reinforcing rod 7 improves the stability of the entire device and prevents the device from tipping over.

[0027] The adjusting device 6 comprises an adjusting plate 61, a slide groove 64, a lower hinge seat 8, an upper hinge seat 3 and an adjusting rod 4. The upper hinge seat 3 is fixed to the middle of the upper end of the back of the frame 1. The slide groove 64 is arranged on the adjusting plate 61. The lower hinge seat 8 is arranged in the slide groove 64 and can move back and forth in the slide groove 64. One end of the adjusting rod 4 is hinged in the upper hinge seat 3, and the other end is hinged on the lower hinge seat 8.

[0028] A locking device is also provided in the slide groove 64 .

[0029] The locking device includes a slider 65, a locking block 66, a stud 63 and a locking nut 62. The slider 65 is arranged in the slide groove 64. The lower hinge seat 8 is fixed to the upper end of the slider 65. There are two locking blocks 66, which are symmetrically fixed on both sides of the slider 65. The stud 63 is fixed on the locking block 66. The nut is arranged on the stud 63 and is threadedly connected to the stud 63.

[0030] The photovoltaic module 2 includes a cover plate 21, a first encapsulation film 22, a cell layer 23, a second encapsulation film 24 and a back plate 25, and the cover plate 21, the first encapsulation film 22, the cell layer 23, the second encapsulation film 24 and the back plate 25 are adhesively and fixedly connected in sequence.
