Description

Technical Field

[0001] The utility model relates to the technical field of flexible photovoltaic support systems, in particular to a flexible photovoltaic support component connection device. Background Art

[0002] Under the dual carbon goals, new energy power generation is a key development project, and vigorously developing photovoltaics will remain a key direction for the future. Centralized photovoltaic power stations can make full use of the rich and stable solar energy resources in deserts and mountainous areas to build large photovoltaic power stations, and access high-voltage transmission systems to supply the electricity generated by photovoltaic power stations to distant power users. The large-span flexible photovoltaic support system can make full use of the space under the photovoltaic power station, and the large-span flexible photovoltaic support system has low steel consumption and investment costs. Therefore, flexible photovoltaic supports are the current key development direction and a rapidly developing technology.

[0003] Compared with traditional photovoltaic brackets, the main feature of flexible photovoltaic brackets is that the rigid purlins in traditional photovoltaic brackets are replaced with prestressed cables (prestressed steel strands). By applying prestress to the cables, they have a certain rigidity, thereby facilitating the installation of photovoltaic modules.

[0004] The flexible photovoltaic support structure mainly consists of 8 parts, including anchoring system, locking system, strut system, piles, steel structure, aluminum alloy connectors, fasteners, etc. The component connector belongs to the range of aluminum alloy connectors, which is used to fix photovoltaic components on steel cables. The connector is an important component for fixing components and transmitting force at nodes.

[0005] One of the currently used component connector forms: It consists of a connector body (component connector a) and a fastener (component connector b). When installing the component, first fix the component connector a to the outer space of the photovoltaic component with a bolt, and then use another bolt to connect the component connector b to the component cable. To complete the node connection, two bolts need to be screwed into the connector body with threaded holes. Under the action of long-term negative wind pressure (back wind) load, the flexible bracket cable body vibrates continuously. If the initial installation state is not strictly tightened according to the designed cable force, the fixing bolts are easy to loosen or even fall off, resulting in uneven force on the component, tearing the frame, and the component falling off, causing economic losses. In addition, the flexible bracket generally has a high clearance, and one bolt is installed on the inside of the photovoltaic component frame. The loose bolts are not easy to find and are difficult to repair.

[0006] The second type of component connector currently used: Chinese patent publication number CN218829701U discloses a photovoltaic component intermediate fixing node in a flexible photovoltaic support system. Figure 1As shown in the figure, the photovoltaic module is fixed by placing the photovoltaic module on the module fixing member, pressing the photovoltaic module with a pressing block, and then passing the U-bolt through the pressing block, the module fixing member and the backing plate in sequence, and finally fixing the three with a fastening nut. The Chinese patent with publication number CN220325532U discloses a photovoltaic module fixing device for a flexible photovoltaic bracket. Figure 2 As shown, the base and the photovoltaic module are detachably connected by the module mounting bolts passing through the mounting holes, and the center of the pressure block is detachably connected to the center of the base by the pressure block fixing bolts. This fixing structure has the following defects: the positioning relationship between the cable and the pressing fastener is relatively random, the frame can slide along the cable, and the module frame is easy to detach from the pressing fastener under the action of external force; more bolts are used, and the installation time is longer.
