Abstract Fossil energy is drying up, but the population is increasing and the social economy is developing continuously。 So there is a growing demand for energy, which forces us to develop new energy sources。 Only 29% of the earth's surface is land，and 71% is the ocean, so the development of marine energy is the trend。 In the process of developing the ocean

energy, most of the countries are actively studying and designing the device that can be used to develop the wave energy。

This design is 20kW semi suspended wave energy device, belongs to a kind of oscillation float type wave power generation device。 First of all, the paper expounds the background and significance of the wave energy power generation, and then analyzes the theoretical principle of the semi suspended wave energy power generation device, then the design of 20kW semi suspended wave energy power generation device is designed to determine the various parameters of the device and draw the engineering drawings of the device。 In the design of the device: first select the appropriate generator, and then design of steady speed energy storage device, then design the growth rate, then the design of the spring slider bar linkage, and finally the entire device of the shell design。

20kW semi suspended wave energy device can generator working process: first through the hollow ball on the wave can capture and re use of the principle of resonance and the connecting rod mechanism, will capture the energy conversion into mechanical energy, and mechanical energy into hydraulic energy, the hydraulic motor through the generator。 20kW semi suspended wave energy device is a new wave power generation device, the design of the device can be suitable for a variety of wave instability of the sea, has a certain practicality。

Key words: wave energy; semi suspended power generation device; resonance principle; linkage mechanism
