Technical Field

[0001] This application relates to the field of photovoltaic product technology, and in particular to a photovoltaic rotating central shaft connector and a photovoltaic central shaft having the photovoltaic rotating central shaft connector. Background Technology

[0002] The photovoltaic (PV) central shaft connector is a crucial component of a PV power plant, supporting the main power generation structure. Choosing a suitable central shaft connector structure can reduce both initial construction costs and subsequent maintenance expenses. It connects to the worm gear assembly, enabling the solar panels to rotate in sync with the sun. Depending on the function of the PV connector, in addition to material requirements, manufacturing costs, ease of installation, and ease of maintenance must also be considered. Existing central shaft connectors utilize several types, including star-shaped, hexagonal, and elliptical pin designs. However, these existing connectors are inconvenient to install, difficult to disassemble, and have high manufacturing costs.

[0003] Therefore, it is necessary to invent a photovoltaic central axis connector to solve the above problems. Utility Model Content

The closed end of the central shaft connector body has a through hole penetrating its wall thickness, a plurality of first positioning pin holes, and a plurality of first bolt mounting holes. The through hole is located at the center of the closed end and is coaxial with the central axis of the central shaft connector body. The first positioning pin holes and first bolt mounting holes are evenly distributed around the through hole, and the central axis of each first positioning pin hole and first bolt mounting hole is parallel to the central axis of the central shaft connector body.

[0006] To facilitate the assembly of the central shaft connector body with the bracket, the outer wall of the central shaft connector body is provided with several guide grooves evenly distributed along its circumference.

[0009] To facilitate the assembly of the central shaft connector body with the worm gear shaft, the outer end face of the closed end of the central shaft connector body has an annular positioning platform. The annular positioning platform is coaxially arranged with the through hole, and the outer diameter of the annular positioning platform is larger than the diameter of the circle containing the central axis of each first bolt mounting hole.

[0010] To facilitate the insertion and positioning of the positioning pin, the first positioning pin hole includes an outer hole and an inner hole that are connected. The inner hole is connected to the inner cavity of the central shaft connector body, and the outer hole is connected to the outside. The diameter of the outer hole is larger than the diameter of the inner hole.

[0011] This utility model also provides a photovoltaic central shaft, including a worm gear shaft and a worm gear connected to the worm gear shaft. The two ends of the worm gear shaft are detachably connected to the above-mentioned photovoltaic rotating central shaft connector.
