[0002] Photovoltaic power generation utilizes the photovoltaic effect of semiconductor materials to convert solar energy into electrical energy with a certain efficiency. It can be directly connected to the power grid through a series of electrical devices, or it can be connected to other devices (such as batteries) to store electrical energy.

[0003] The overall hoisting and installation of offshore photovoltaic (PV) brackets has always been a major challenge in offshore PV projects. Currently, there are some purely mechanical hoisting tools on the market to assist in the installation, but due to the harsh conditions of offshore installation, the issues of safety and efficiency have not been well resolved.

[0004] Currently, after the entire offshore photovoltaic (PV) support structure is hoisted to the designated installation site at sea, workers manually separate the ring-shaped slings from the PV support's lifting points by climbing onto the support structure. This method of operation poses significant safety hazards and low work efficiency, and also greatly impacts the overall project timeline. Summary of the Invention

[0005] 1. Technical problems to be solved The purpose of this invention is to solve the problem that in the existing technology, offshore photovoltaic support systems require workers to climb onto the support system to manually separate the ring sling from the photovoltaic support system's lifting point, which poses a great safety hazard. Therefore, this invention proposes a safe and efficient offshore photovoltaic support system lifting beam.

[0006] 2. Technical Solution To achieve the above objectives, the present invention adopts the following technical solution: A safe and efficient offshore photovoltaic support beam includes a frame beam and multiple spreader beams.

The frame beam includes four central beams arranged in a rectangular shape, wherein two of the central beams are fixedly connected to both ends of a first side beam, and two of the central beams are fixedly connected to both ends of a second side beam. Adjacent first side beams and second side beams are fixedly connected by a first adapter. Both ends of the bottom of the spreader beam are provided with lifting points, and fixed pins are fixedly connected to the lifting points. A DC electric cylinder is fixedly connected to the lifting point, and the output end of the DC electric cylinder is connected to the input end of the fixed pin.

[0007] Preferably, the top of the frame beam is fixedly connected with a plurality of annular slings arranged in a rectangular pattern, and the frame beam is provided with mounting pins corresponding to the annular slings.

[0008] Preferably, a control cabinet and a storage battery are fixedly mounted on the top of the frame beam.

[0009] Preferably, both ends of the middle beam are fixedly connected to a plurality of first connecting plates, and the first connecting plates are provided with a plurality of first connecting holes.

[0010] Preferably, a second connecting plate is fixedly connected to both the first side beam and the second side beam, and the second connecting plate is provided with a plurality of second connecting holes.
