Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic components, in particular to a solar cell fixing device. Background Art

[0002] Solar cells are usually installed at high altitudes, and when they are fixed, the installers need to manually position the solar cells first, and then lock the buckles. Since solar cells are heavy, this can easily cause poor coordination, causing the solar cells to fall from high altitudes. In addition, two solar cells are usually locked at the same time with a buckle, so the two solar cells need to be positioned at the same time before the buckle between them is locked. This installation method is also very inconvenient and has the same safety hazards.

[0003] The existing Chinese patent CN204046492U discloses a solar cell fixing device, which can slide into the fixed end fixing beams from the side in sequence when installing the solar cell, and then block the two ends of the end fixing beams through the fixing beam heads, which is convenient and quick to install, and has higher safety;

[0004] Commonly used solar cell sizes on the market include 266, 182, 210 and other specifications, and the spacing between the end fixing beams of the above-mentioned solar cell fixing device is fixed. When installing solar cells of different specifications, either the fixing device of the corresponding specification is replaced, or the end fixing beams are reinstalled with bolts, which makes the single solar cell fixing device less usable.

The threaded rod 1 403, the threaded rod 2 405, and the threaded rod 3 406 are of the same thickness, and the number of threads on the threaded rod 2 405 is threaded. The number of threads on the threaded rod 1 403 is twice that of the threaded rod 1 403, and the number of threads on the threaded rod 3 406 is three times that of the threaded rod 1 403. The fixed horizontal frame 2 is used as a fixed component. The spacing between the three movable horizontal frames 3 and the spacing between the movable horizontal frame 3 and the fixed horizontal frame 2 are adjusted by the adjustment mechanism 4 to match solar cells of different specifications. The threaded rod 1 403, the threaded rod 2 405, and the threaded rod 3 406 are driven to rotate by rotating the rotating shaft 402, thereby moving the corresponding slide plate 1 404.
