Description

Technical Field

[0001] This utility model relates to the field of photovoltaic mounting brackets, specifically to a pressure block fastener for installing lightweight photovoltaic modules. Background Technology

[0002] With technological advancements, solar photovoltaic (PV) modules are no longer limited to traditional rigid forms. "Flexible" lightweight PV modules are gradually becoming a new favorite in the new energy field. Lightweight PV modules are significantly lighter than traditional modules, have a clear structural stress distribution, and offer high structural safety. They utilize thin-film batteries and eliminate the need for glass. Abandoning aluminum alloy frames, they use composite materials for irregularly shaped module frames. Bolted connections to the module backplate can damage the frame, and traditional clamping methods cannot securely fix the module. When the module is subjected to lateral forces, it can slip, potentially causing it to separate from the support structure in severe cases. Utility Model Content

The lightweight photovoltaic module is fixed on the reinforcing support unit 13 and the fitting protrusion 14. It also includes a pressure block 1 and a fastener 2. The pressure block 1 and the fastener 2 are generally L-shaped. The reinforcing support unit 13 is generally an upright trapezoidal structure, which facilitates the adjustment of the fastener 2 up and down to adjust the tightness between the free end of the fastener 2 and the reinforcing support unit 13.

[0021] The pressure block 1 includes a first side 11 and a second side 12. A reinforcing support unit 13 is provided on the first side 11, and an engaging protrusion 14 is provided on the reinforcing support unit 13. A through hole 15 is provided on the first side 11 near the second side 12. A fastener 2 is inserted through the through hole 15. The fastener 2 includes a first side 21 and a second side 22. The second side 22 is inserted through the through hole 15. The free end of the first side 21 abuts against the reinforcing support unit 13. A through hole is provided on the second side 12, and a through hole 23 is provided on the second side 22. The through hole on the second side 12 and the through hole 23 on the second side 22 are locked together by bolts 3 and nuts 4.

[0022] The perforation on the second side 12 of the pressure block is a circular perforation, and the perforation 23 on the second side 22 of the fastener is an oblong perforation.

[0023] or

[0024] The perforation on the second side 12 of the pressure block is a waist-shaped perforation, and the perforation 23 on the second side 22 of the fastener is a circular perforation.

[0025] The second side 12 of the pressure block is provided with a first protrusion 16 (i.e., a wedge block) with a wedge-shaped surface on the side facing the fastener 2. Correspondingly, the second side 22 of the fastener is provided with a second protrusion 24 (i.e., a wedge block) with a wedge-shaped surface on the side facing the pressure block 1.

[0026] The thick end of the first protrusion 16 on the pressure block 1 is on top, and the thin end of the first protrusion 16 on the pressure block 1 is on the bottom; correspondingly, the thin end of the second protrusion 24 on the fastener 2 is on top, and the thick end of the second protrusion 24 on the fastener 2 is on the bottom.

The lightweight photovoltaic module is passed through the gap between the reinforcing support unit 13 and the fitting protrusion 14, the first side 11 of the clamping block and the first side 21 of the fastener. Then, the bolts 3 and nuts 4 are tightened further, so that the fastener 2 clamps the edge of the lightweight photovoltaic module downward under the combined action of the first protrusion 16 of the second side 12 of the clamping block and the second protrusion 24 of the fastener 2. At the same time, the free end abuts against the inclined part of the lightweight photovoltaic module to better fix the lightweight photovoltaic module.
