A series flapping wing power generation device using renewable energy

Abstract

The invention discloses a series connection flapping wing power generating device employing renewable energy sources. The series connection flapping wing power generating device utilizes ocean (river) energy and solar energy and collects series connection vibration flapping wing energy. The series connection flapping wing power generating device mainly comprises an H-shaped frame structure, two blades, an incomplete gear transmission mechanism, a band pulley transmission mechanism, an electromagnetic suction force device and the like. When the series connection flapping wing power generating device works, initial attack angles of the two blades are ensured by the electromagnetic suction force device, and self-starting of heaving and pitching motion of the blades is realized; with the adoption of a minitype solar power generating device to supply power to the electromagnetic suction force device, the objective of being independent of traditional energy is realized; and with the adoption of a series connection flapping wing structure, a varying flow field generated by the motion of the upstream blade promotes energy collection of the downstream blade, and the energy collection efficiency is improved with the utilization of the advantage of interaction among multiple wings. The series connection flapping wing power generating device converts the heaving and pitching motion of flapping wings to rotation of a middle shaft, collected kinetic energy is transferred to a power output device through the middle shaft for generating electric energy, and the electric energy is finally input to a power grid.

Problems solved by technology

[0004] The existing flapping wing energy-absorbing mechanism usually has only one blade. This design ignores the promotion effect of multiple blades in series on the energy harvesting efficiency through the interaction of the flow field, and its energy harvesting efficiency is not optimal; The pitching motion of the wing is usually driven by a motor, combined with a special transmission structure such as a crank-connecting rod structure to convert the rotation of the motor into a translational motion to realize the ups and downs. This design not only increases the external energy input, reduces the energy output rate, but also makes the structure Complicated, reducing structural adaptability
