Multifunctional ecological floating island capable of purifying water

A multifunctional ecological floating island capable of purifying water quality comprises an extended buoyancy plate, a water circulation buoyancy plate, a long connecting rod, a short connecting rod, a solar panel, an energy storage battery, a support frame, a water circulation turbofan and a second filter screen. Plants are placed on the expansion buoyancy plates; the plurality of expansion buoyancy plates and the plurality of water circulation buoyancy plates are connected together through the long connecting rods and/or the short connecting rods to form a floating island; a solar panel is installed on the water circulation buoyancy plate and connected with an energy storage battery, the support frame is installed at the bottom of the water circulation buoyancy plate, a water inlet is formed between the support frame and the water circulation buoyancy plate, the second filter screen is installed at the bottom of the support frame, and at least two through holes are formed in the side wall of the support fr
