[0002] Offshore photovoltaic platforms refer to photovoltaic power station facilities used on the sea surface. They are a new type of photovoltaic power generation. Because the ocean environment is relatively open, there are no obstructions, and the water can fully reflect light, offshore photovoltaic platforms have higher power generation than land photovoltaic power stations. It is estimated that compared with land photovoltaics, offshore photovoltaic power generation can increase by 5% to 10%.

[0003] The existing offshore photovoltaic platforms still have certain deficiencies in the transportation process: the existing offshore photovoltaic platforms are generally directly hoisted on the ship deck by a crane and fixed by anchor cables during shipment. However, this method requires very high precision in the operation of the crane during actual operation. After the platform is placed on the ship deck, it is inconvenient to perform fine adjustments to its position, which can easily cause bumps and damages to the ship and the platform. Based on the deficiencies of the existing technology, the present invention designs an offshore photovoltaic platform transportation device. Summary of the invention
