Study On The Wave Generating System Based On Pneumatic Motor

The vast ocean provides abundant resources for human beings,endless waves can provide endless dynamic energy,but our utilization of the sea is not high,the use of this energy is extremely limited.Wave power generating system makes use of ocean waves as a source of power and ultimately transmits electric energy through energy conversion.This paper mainly studies a new low-power wave power generating system.That is to say,the gas in the closed cavity produces a driving force based on the action of wave floating up and down,and then the pneumatic mechanism is driven to move by the internal pressure and flow of the gas,so that the mechanism terminal output rotary motion,driving the low-power generator to transmit electricity.Firstly,this paper introduces the wave power generation technology and expounds the purpose and significance of the research combined with the actual need of our country,and describes in detail the research status of the wave power generating system at home and abroad.By analyzing the characteristics of chain drive,wind tunnel and pneumatic motor wave power generation,the design scheme of pneumatic motor power generating system is determined.Secondly,the working principle of the pneumatic system,the principle of wave kinetic energy conversion and the working characteristics of the pneumatic system are analyzed.The modules of absorbing wave energy,energy conversion,energy storage,desalination and small-power heating are designed around the pneumatic motor type low-power coastal wave power generation system.Then,the main body,cam,mandrel and connecting rod of the pneumatic motor are calculated and designed so as to define the parameters of the variable speed gear of the generator.Finally,the voltage,current and power values of the power generating system are obtained through prototype development and experiment,the power generation efficiency and capacity-generating efficiency are calculated to verify the pneumatic motor shore.The rationality and validity of the design of coastal wave power generating system show that the system can initially collect wave kinetic energy,convert wave kinetic energy into gas internal kinetic energy in order to achieve low-power generation finally.
