Simple pendulum-based wave-energy power generation device

Abstract

The invention discloses a simple pendulum-based wave-energy power generation device. The simple pendulum-based wave-energy power generation device comprises a swing device, wherein the swing device isconnected with a power generation device through a transmission device. The simple pendulum-based wave-energy power generation device is arranged on a floating body, the floating body heaves and shakes along with the movement of wave, absorbs the energy of the wave and converts the energy of the wave to the kinetic energy and potential energy of the floating body, the floating body is taken as abase of a simple pendulum in the swing device, and the movement of the floating body under the action of the wave becomes an excitation source for the simple pendulum; and the simple pendulum convertsthe kinetic energy and potential energy of the floating body to mechanical energy, the transmission device transmits the bidirectional swing mechanical energy of the simple pendulum to the power generation device, and the power generation device converts the transmitted mechanical energy to electric energy. According to the simple pendulum-based wave-energy power generation device, the power generation efficiency is increased; and moreover, due to the structural design, the power generation device is enabled to be away from sea surface, so that the corrosion resistance of the power generationdevice is ensured, and the safety and reliability are improved.

Description

technical field [0001] The invention belongs to the technical field of new energy development and utilization, in particular to a pendulum-based wave energy generating device. Background technique [0002] Developing and utilizing my country's marine energy and resources and reducing dependence on traditional fossil energy can alleviate energy problems to a certain extent. At the same time, ocean energy is also a kind of green renewable energy, which has little impact on the environment and has broad development prospects. [0003] The essence of converting wave energy into electrical energy is a process of converting the water momentum of the wave into mechanical relative motion, and then driving the generator to generate electricity. How to avoid energy loss in the conversion process is the core. Because in actual waves, water molecules do not move up and down in theory, but move in an elliptical trajectory, so many wave energy power generation devices based on simple mo...

AI Technical Summary

Problems solved by technology

Because the actual wave does not move up and down in theory, but moves in an elliptical trajectory, so many wave energy power generation devices based on simple motion cannot exert the theoretical power generation efficiency

[0004] The traditional single pendulum wave power generation device only uses rotation in one direction to generate power, which has low power generation efficiency and low energy utilization rate; patent CN102297068A proposes a wave power generation device that captures wave energy in a two-dimensional direction and uses a planar generator to generate power , but the system structure is complex and difficult to maintain

[0005] Due to the characteristics of poor stability, low frequency and strong destructiveness of waves, the efficiency and reliability of wave energy generation devices are low, which restricts the wide application of wave energy.
