Description

Technical Field

[0001] The utility model relates to the field of photovoltaic equipment, and in particular comprises an aluminum profile connector for fixing photovoltaic components. Background Art

[0002] The current photovoltaic module fixing method used in the domestic and international photovoltaic markets generally utilizes an aluminum profile side clamp, a middle clamp, and stainless steel bolts. With the optimization and cost reduction of photovoltaic modules, the aluminum profile frame of the module has been optimized from having C-surfaces on all four sides to only retaining C-surfaces on the two long sides, while the C-surfaces on the short sides have been eliminated. When the module is installed horizontally and the clamp is fixed to the short side frame, the C-surface is eliminated, resulting in the module frame being held tightly by the aluminum profile's approximately 10mm wide clamp. The disadvantage of this fixing method is that it can easily deform and shift the photovoltaic module during typhoons, causing the photovoltaic module to be loosely installed. In severe cases, the photovoltaic module can be blown off and cause property damage.

[0003] Furthermore, if the modules are mounted horizontally and conventional aluminum profile clamps are used to secure the modules on the long side frames, an additional aluminum profile support plate is required. The PV modules are secured together using the aluminum profile clamps, the aluminum profile support plate, and bolts. This additional aluminum profile support plate inevitably increases project construction costs and reduces overall profitability.

[0004] Therefore, there is an urgent need for a new type of aluminum profile connector for fixing photovoltaic modules, which can eliminate the conventional aluminum profile side pressure blocks and middle pressure blocks, save construction costs, and improve the safety of module installation.

[0019] The present invention will be further described below with reference to the following embodiments. The following embodiments are provided solely to facilitate understanding of the present invention. It should be noted that, within the scope of the present invention, modifications may be made by a person skilled in the art without departing from the principles of the present invention. Such improvements and modifications are also within the scope of the claims of the present invention.

[0020] As an example, Figures 1 to 4As shown, this aluminum profile connector for fixing photovoltaic modules includes: a C-shaped steel beam 1, an aluminum profile connector 2 and a hexagon socket bolt 6; a module frame 4 is provided on the long side of the photovoltaic module 3, and a plurality of module long side frame C surfaces 5 are provided at the bottom of the module frame 4 facing the inside of the photovoltaic module 3;

[0021] The two side flanges of the C-shaped steel beam 1 face upwards, and the top of the flanges are curled inwards. Several limiting stiffening ribs are provided under the aluminum profile connector 2, and the flanges of the C-shaped steel beam 1 are inserted between the limiting stiffening ribs of the aluminum profile connector 2.

[0022] In this embodiment, an aluminum profile connector 2 is fixedly connected to the bottom of the long side frame C surface 5 by a hexagon socket bolt 6, and three limiting stiffening ribs are provided under the aluminum profile connector 2, two of which form slots on the side of the aluminum profile connector 2 away from the photovoltaic component 3, and the outer wing plate curling of the C-shaped steel beam 1 is inserted into the slot.

[0023] Of the three limiting stiffening ribs below the aluminum connector 2, the one closest to the photovoltaic module 3 mates with the inner side of the flange of the inner flange of the C-shaped steel beam 1. A limiting stiffening rib is also provided above the aluminum connector 2, and this rib is located inside the hexagon socket bolt 6. The outer side of the module frame 4 abuts the inner side of this limiting stiffening rib above the aluminum connector 2.

[0024] The aluminum connector 2 is secured to the top of the C-shaped steel beam 1 with hexagon socket head cap bolts 6. The spacing between the two C-shaped steel beams 1 requires careful consideration of the module dimensions before installation and positioning. The aluminum connector 2 and the C-shaped steel beam 1 are secured together with hexagon socket head cap bolts 6, which penetrate between the flanges on either side of the C-shaped steel beam 1 and the aluminum connector 2. When the project site is near coastal areas or areas with high wind loads, no fewer than three aluminum connectors 2 must be secured to each side of the long side frame C-side 5 of the module to ensure a secure and reliable installation of the photovoltaic modules 3.

[0025] This photovoltaic module mounting assembly structure, after the photovoltaic bracket base and diagonal beam are installed, is precisely positioned on the diagonal beam using hexagon socket head bolts 6 according to the design dimensions of the C-shaped steel crossbeam 1. The long side frame C-surface 5 of the photovoltaic module 3 is fastened to the outer bolt holes of the aluminum profile connector 2 using hexagon socket head bolts 6, and is pre-assembled.

[0026] The integrated assembly of the photovoltaic module 3 and the aluminum connector 2 is placed on the C-shaped steel beam 1. The three cantilevered limiting stiffening ribs on the bottom of the aluminum connector 2 are clamped to the inner curled edge of the top side of the C-shaped steel beam 1. The cantilevered length of the three limiting stiffening ribs is appropriately extended to prevent slippage. After the upper and lower C-shaped steel beams 1 are clamped and positioned, the two C-shaped steel beams 1 and the aluminum connector 2 are securely fastened with long-threaded hexagonal bolts 6, forming a strong and reliable connection between each photovoltaic module 3 and the photovoltaic bracket.
