Description

Technical Field

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (assemblies), controllers and inverters. The main components are made of electronic components. In recent years, more and more photovoltaic equipment companies have chosen to cooperate with residential houses to install photovoltaic panels on roofs. While meeting electricity demand, excess electricity can be sold to the power grid. Therefore, when installing on residential roofs, lifting equipment is required to lift the photovoltaic panels and installation components.

[0003] A Chinese patent with publication number: CN117262994A discloses a lifting machine for installing photovoltaic panels, including a fixed base plate, a support structure, a lifting structure, a hanging structure, a photovoltaic panel fixing structure and an auxiliary stabilizing structure.

[0004] However, there are certain deficiencies in the above technical solution: 1. When the above technical solution is used, the second connecting seat is driven to rotate to a certain extent by driving the electric push rod, thereby transferring the suspended workpiece assembly. However, when the electric push rod is rotated, it is blocked by the second connecting seat from continuing to rotate, so it can only continue to rotate to a very small extent;

[0005] 2. The lifting structure of the above technical solution drives the lifting of the photovoltaic fixed structure at the bottom by the extension and contraction of the connecting rod in the fixed tube. However, the lifting stroke of such a lifting structure is short and can only lift the photovoltaic panels. The base required for the installation of the photovoltaic panels cannot be lifted well.
