Description

Technical Field

[0001] This utility model relates to the field of photovoltaic bracket installation technology, specifically a modular splicing buckle for photovoltaic brackets that is easy to assemble. Background Technology

[0002] Photovoltaic support structures are the core structures that support photovoltaic panels and ensure their stable reception of solar radiation. They must simultaneously meet three core requirements: load-bearing safety, angle adaptability, and environmental tolerance. They are key components connecting photovoltaic panels to the mounting foundation (roof, ground, water surface, etc.) in a photovoltaic system. Their design and selection directly affect the power generation efficiency, lifespan, and system safety of the photovoltaic panels.

[0003] With the continuous development of the photovoltaic industry, the installation area of ​​photovoltaic panels is getting larger and larger, and the area of ​​the brackets used to support the photovoltaic panels also needs to be increased. Chinese Patent Announcement No. CN 207368928 U discloses a photovoltaic bracket buckle structure, which includes a bracket seat and a pressure block. The pressure block is located on the upper part of the bracket seat and they are connected by bolts and nuts. The bracket seat includes two sides and an upper connecting surface. A hook is provided at the lower end of the side. A first protruding edge is provided on the inner wall of the side above the hook. A second protruding edge is provided on the inner wall of the side above the first protruding edge. A third protruding edge is provided at the connection between the side and the upper connecting surface. The nut is a square nut.

[0004] The aforementioned snap-fit ​​structure uses a snap-fit ​​base and a pressure block to connect two brackets. However, the snap-fit ​​base and pressure block of the aforementioned snap-fit ​​structure can only fix two brackets together. When installing large-area photovoltaic panels, a large number of brackets are required, thus requiring a large number of snap-fit ​​structures, which increases material costs, increases the time for installing brackets, and reduces installation efficiency.

[0034] The pressure frame 16 is perpendicular to the main frame 11, and the bottom surfaces on both sides of the pressure frame 16 are respectively attached to the two brackets 3.

[0035] By adopting the above technical solution, multiple clamping plates 13 can cooperate with each other to fix two brackets 1 2 on both sides of the main frame 11, and the pressure frame 16 can cooperate with the main frame 11 to fix two brackets 2 3, thereby realizing the connection and fixation of two brackets 1 2 and two brackets 2 3. The operation is simple and can connect four brackets at the same time. When installing photovoltaic panels on a large area, the number of clamping structures 1 used can be reduced, thus reducing material costs.

[0036] In this embodiment, a second spring 18 is sleeved on the outer side of the end of the adjusting bolt 17 away from the nut 19.
