The algae unit is composed of a solar power generation system, a wave energy piezoelectric power generation system and an ultrasonic transducer. The solar power generation system is composed of a photovoltaic power generation system and a polygonal conical shell with an inner cavity; The piezoelectric vibrator is composed of a fixed piezoelectric vibrator and a connecting beam; the ultrasonic transducer includes a pre-tightening bolt, a counterweight, a plane beam, a rectangular piezoelectric ceramic sheet with a central hole and a transmitting end. All-weather power generation is performed by solar energy and wave energy, and the ultrasonic algae removal function of the device of the present invention based on the phased array principle is realized. The device of the invention is based on green energy, and has the advantages of green algae removal, no pollution, large algae removal area, good effect and the like.

Description

technical field [0001] The invention belongs to the technical field of ecological algae removal, and in particular relates to an array type ultrasonic algae removal device and method for synergistic power generation of solar energy and wave energy. Background technique [0002] The emergence of eutrophication in water bodies makes aquatic plants and phytoplankton in slow-flowing water bodies such as reservoirs, lakes, and bays multiply rapidly using nutrients in the water, resulting in a decrease in dissolved oxygen content in the water and deterioration of water quality, which causes fish and Other aquatic organisms die, thereby affecting the utilization of water bodies. Adopting green methods to suppress eutrophication of water body is of great significance for controlling water body pollution. At present, many international or domestic research units have proved through relevant experiments that the use of ultrasonic technology can inhibit the growth and reproduction of ...
