Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a corner bracket and its installation structure with a photovoltaic frame. Background Technology

[0002] In photovoltaic (PV) modules, corner brackets are key components connecting the frame or structural framework of PV panels. Their core functions are to enhance structural stability, distribute stress, protect the module, and improve installation efficiency and compatibility. The triangular or L-shaped design of corner brackets (such as right-angle corner brackets) utilizes the principle of geometric stability to distribute the stress on the frame and reduce torsional deformation caused by temperature changes or mechanical impacts. This is especially suitable for modules in large-scale PV power plants that need to be exposed to the outdoors for extended periods.

[0003] In the existing technology, the frame of photovoltaic modules is usually made of aluminum alloy profiles. The corner brackets themselves need to be welded and fixed to the corners of the frame with bolts to tightly connect the four frames into a rigid frame. Utility Model Content

[0004] This utility model solves the problems in related technologies and proposes a corner bracket and its installation structure with a photovoltaic frame. The corner bracket itself is connected by a wedge block and a wedge groove, which saves installation and disassembly time and improves work efficiency compared with welding. It is especially suitable for occasions that require frequent assembly and disassembly. The connection between the corner bracket and the photovoltaic frame is achieved by the cooperation of the mounting teeth and the slot, which eliminates the need for bolts, greatly simplifying the installation process and saving installation time and labor costs.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a corner code, including an L-shaped corner code body, the corner code body including a first body and a second body arranged vertically, one end of the first body having a wedge block and one end of the second body having a wedge-shaped groove adapted to the wedge block, and the end faces of the first body and the second body that contact the photovoltaic frame having mounting teeth formed.

[0006] As a preferred embodiment, both the first body and the second body are L-shaped structures. The first body includes a first side plate and a first bottom plate, and the second body includes a second side plate and a second bottom plate. The first end face of the first side plate and the first bottom plate are integrally formed, and the first end face of the second side plate and the second bottom plate are integrally formed. Mounting teeth are provided on the second end face of the first side plate and the second end face of the second side plate and the second bottom plate. A wedge is formed on the third end face of the first side plate, and a wedge-shaped groove adapted to the wedge is formed on the third end face of the second side plate. The first bottom plate and the second bottom plate are integrally formed.

[0007] As a preferred embodiment, the first body includes a third base plate, a third side plate, and a fourth side plate, and the second body includes a fourth base plate, a fifth side plate, and a sixth side plate. The third base plate is bent integrally with the third and fourth side plates perpendicular to each other, and the fourth base plate is bent integrally with the fifth and sixth side plates perpendicular to each other. The ends of the third and fourth side plates that are not connected to the third base plate, as well as the ends of the fifth and sixth side plates that are not connected to the fourth base plate, are provided with mounting teeth. The ends of the third and fifth side plates that are connected to each other are provided with matching wedges and wedge grooves.

[0008] In another aspect, this utility model also provides an installation structure for a corner bracket and a photovoltaic frame. The photovoltaic frame includes a first mounting groove and a second mounting groove, a buffer cavity is provided between the first mounting groove and the second mounting groove, and a slot is provided on the side of the second mounting groove where the mounting teeth are installed.

[0009] As a preferred embodiment, the second mounting groove is formed by a U-shaped plate, a first horizontal plate, a first vertical plate and a fifth base plate, which has an opening on one side. The end of the fifth base plate away from the first vertical plate is bent into a U-shaped slot. The U-shaped plate, the first horizontal plate and the first vertical plate also form a U-shaped slot. The first body and the second body are placed in the second mounting groove and the mounting teeth are engaged in the slot.

[0010] In another aspect, this utility model also provides an installation structure for a corner bracket and a photovoltaic frame, wherein the photovoltaic frame includes a third mounting groove and a fourth mounting groove, and the fourth mounting groove and the mounting tooth side are both provided with a slot.

[0011] As a preferred embodiment, the fourth mounting groove is formed by the second horizontal plate, the second vertical plate and the sixth bottom plate, which together form an opening on one side; the end of the sixth bottom plate away from the second vertical plate is bent into a U-shaped slot, and the end of the second horizontal plate that is connected to the third horizontal plate of the third mounting groove is bent towards the side closer to the fourth mounting groove to form a slot, and the first body and the second body are placed in the fourth mounting groove and the mounting teeth are engaged in the slot.

[0012] Compared with existing technologies, the advantages of this utility model are as follows: The corner bracket of this utility model is connected by a wedge block and a wedge groove. Compared with welding, the connection method of the wedge block and the wedge groove does not require professional welding equipment and complicated operating procedures. During installation, the connection can be completed simply by accurately inserting the wedge block into the wedge groove and applying appropriate pressure. During disassembly, the two bodies can be easily separated by simply reversing the operation and removing the wedge block. This greatly saves installation and disassembly time and improves work efficiency, especially suitable for occasions that require frequent assembly and disassembly. The connection between the corner bracket and the photovoltaic frame is achieved through the cooperation of the mounting teeth and the slot. The cooperation design of the mounting teeth and the slot can provide greater friction and locking force. The tightness ensures a secure connection between the corner bracket and the photovoltaic frame, preventing loosening and allowing it to withstand various environmental factors (such as wind and vibration) during long-term use, thus guaranteeing the structural stability of the photovoltaic modules. The boltless connection significantly simplifies the installation process, saving installation time and labor costs. Especially in large-scale photovoltaic power plant installations, this connection method can significantly improve construction efficiency and shorten the construction period. The boltless connection avoids problems such as loose bolts and rust, reducing maintenance workload and costs caused by bolt failure. At the same time, this connection method also facilitates the disassembly and replacement of photovoltaic modules, improving the maintainability of the system. Attached Figure Description
