Abstract

The invention discloses a wave power generation system based on the magnetic gear speedup effect and a designing method of the wave power generation system. The wave power generation system comprisesa tubular linear motor, an outer float buoy and an inner float buoy; the tubular linear motor comprises a primary part and a secondary part, and a gas gap is formed between the primary part and the secondary part; the outer float buoy is connected outside the primary part in a sleeving mode, and the inner float buoy is arranged above the secondary part and is rigidly connected with the secondary part; by adjusting the counterweight of the outer float buoy, the vibration frequency and moving speed of the outer float buoy are close to or equal to the vibration frequency and moving speed of the ocean wave; and by adjusting the draught depth of the inner float buoy, the oscillation period of the inner float buoy is kept away from the oscillation period of the ocean wave. The wave power generation system has the beneficial effects that the tubular linear motor based on the magnetic gear speedup effect is combined with the wave power generation system, the shortcomings of low efficiency of wave power generation and low power generation cost performance are effectively overcome, and an efficient and accurate analytical calculation method is provided for the design of the systems.

Description

technical field [0001] The invention relates to the technical field of renewable energy utilization, in particular to a wave power generation system based on the speed-up effect of magnetic gears and a design method thereof. Background technique [0002] With the rapid development of the global economy, the human demand for energy consumption is bound to increase. However, most of the world's energy consumption comes from fossil fuels. As a non-renewable energy source, fossil energy has caused a series of problems during its combustion and use, such as the greenhouse effect, environmental pollution, and geological and ecological damage. Therefore, the coordinated and sustainable development of energy consumption and the environment is the common concern of all countries in the world today. The development and utilization of new renewable and clean energy can not only meet the increasing energy consumption needs of human beings, but also improve the environment and achieve ...
