Description

Technical Field

[0001] The present invention relates to the technical field of clean energy power generation, and in particular to an offshore floating modular integrated power generation platform. Background Art

[0002] Electricity generation through traditional energy sources like coal and oil is causing serious environmental problems, and limited traditional energy will struggle to meet demand in the near future. Wind, solar, and wave energy are important renewable, clean energy sources, and their utilization can address energy supply and the resulting environmental challenges in human development.

[0003] Wind and solar power generation technologies are relatively mature, but they often occupy significant land areas. With population growth and increasing land scarcity, the availability of land-based wind and solar power installations is extremely limited. The ocean, which makes up the majority of Earth's surface area, holds enormous energy reserves. Single wind and solar power generation systems installed in the deep sea are subject to poor stability due to their inherent buoyancy and the influence of wind and waves. While wave energy is ubiquitous in the vast ocean, wave energy converters (WECs) are economically unsuitable for large-scale development and utilization due to their low energy capture efficiency.

[0004] Integrated energy utilization is an effective way to reduce costs and improve power generation efficiency. Platform installation, integrated power generation platforms, and modular connections can significantly improve the stability of individual power generation units and make them suitable for large-scale installations. Existing technologies for integrated power generation using wind, solar, and wave energy are still in their early stages, and the effective integration of these three through modular platforms is crucial. Summary of the Invention

[0005] 1. Technical problems to be solved

[0025] (2) A floating platform with a fixed draft is placed at sea. Wind turbines convert wind energy into electricity, and photovoltaic panels convert solar energy into electricity.

The circular guide post of the second docking member first engages with the circular guide hole of the first docking member. Then, the claws of the first docking member and the second docking member form a self-locking connection. Then, the two modules are pulled apart. The hinge portion of the second docking member in the third docking member is pulled out. At the same time, the claws of the second docking member and the third docking member form a self-locking connection and reach the limit position. The two modules move relative to each other through the hinge of the second docking member and are used normally. When the two modules are separated, the self-locking effect of each claw is released, and the hinge portion of the second docking member is pushed back into the third docking member.
