Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic components and relates to a fastening clamp specially used for photovoltaic components. Background Art

[0002] Solar panels, or photovoltaic panels, are devices that convert sunlight into electricity. Photovoltaic modules utilize the photovoltaic effect (also known as the photovoltaic effect), a process in which semiconductor materials absorb sunlight and generate current to convert solar energy into electricity. Photovoltaic clamps are important accessories used to secure, connect, and support photovoltaic modules and their associated components in solar photovoltaic power generation systems. Traditional module replacement processes currently struggle to ensure that the new modules are the same size and thickness as the original modules. Therefore, the thickness of both sides of the photovoltaic clamps cannot be guaranteed to be consistent. Traditional clamps, when pressed tightly, can only ensure that the thicker side of the module is compacted, leaving a gap on the other side, making it impossible to simultaneously compress both sides.

[0003] The Chinese utility model patent with authorization announcement number CN209120100U discloses an insert-type photovoltaic panel assembly connection structure, including a connecting plate, with positioning grooves provided on both sides of the connecting plate, and a rubber layer tightly fitted on the inner wall of the positioning groove. Two positioning holes are provided on both sides of the connecting plate, and threaded grooves are provided on the inner wall of the positioning holes. Fixing bolts are provided inside the positioning holes. Photovoltaic panels are fixedly installed inside the positioning grooves, and fixing holes are provided near the openings inside the positioning grooves. This technical solution fixes the photovoltaic panel through the rubber layer and will not affect the normal use of the photovoltaic panel. However, this technical solution fixes the photovoltaic panel through fixing bolts and fixing holes, and a gap may be generated between the photovoltaic panel and the connecting plate, thereby affecting the fixing effect of the photovoltaic panel.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Please see the attached Figure 1-2A fastening fixture for photovoltaic modules 7 includes a C-shaped frame 1. A lifting slot 101 is provided on the side of the frame 1 away from the photovoltaic module 7. A fastener 2 capable of sliding up and down along the lifting slot 101 is provided in the frame 1. One end of the fastener 2 extending out of the lifting slot 101 is bent upward to form a C-shaped portion 201. A first bolt 5 is threadedly connected to the upper side of the C-shaped portion 201. The lower end of the first bolt 5 passes through the C-shaped portion 201 and is threadedly connected to the frame 1. A flexible layer 3 in contact with the photovoltaic module 7 is glued inside the fastener 2. The flexible layer 3 is a triangle, and the inclined surface is inclined upward toward the photovoltaic component 7. When in use, the staff places the photovoltaic component 7 in the frame 1. Then, the staff rotates the first bolt 5. Under the action of the thread, the fastener slides downward along the lifting slot 101 until the flexible layer 3 contacts the side of the photovoltaic component 7, and the flexible layer 3 is completely squeezed onto the side of the photovoltaic component 7, thereby reducing the gap between the flexible layer 3 and the photovoltaic component 7, and expanding the contact area between the photovoltaic component 7 and the fastening clip, thereby improving the fastening effect of the fastening clip on the photovoltaic component 7.

[0018] In this embodiment, a second bolt 6 is threadedly connected to one end of the upper side of the frame 1 close to the photovoltaic component 7, and the lower end of the second bolt 6 passes through the frame 1 and is threadedly connected to the upper side of the fastener 2. When in use, the second bolt 6 can further push the fastener 2 to squeeze and contact the side of the photovoltaic component 7, further improving the fastening effect of the fastener 2 on the photovoltaic component 7.

[0019] In this embodiment, a wear-resistant layer 4 is glued to the lower side of the frame 1. When in use, the wear-resistant layer 4 prevents direct contact between the photovoltaic module 7 and the frame 1, thereby preventing damage caused by friction between the photovoltaic module 7 and the frame 1.

[0020] In this embodiment, the wear-resistant layer 4 is made of a wear-resistant material such as a rubber pad.

[0021] In this embodiment, the flexible layer 3 is made of a flexible material such as rubber.

[0022] In this embodiment, the fastener 2 is made of stainless steel.
