| The ocean wave energy is abundant and environmental.Moreover,it is used to provide large-scale power for people's daily life.Meanwhile,it can be used for single generator device to supply power for beacon,light buoy or underwater vehicle.The micro wave energy generator device is one of them which is equipped with great mobility,and the power can be supplied to any devices when it was directly assembled on them.In the light of present situation,it has great development prospect.Thus,the object of the research is a self-adaptation inversion type wave energy generator device,and it was a kind of new micro wave energy generator device.In details,it utilizes the absorber blades group to convert the low-speed high-torque wave energy into the electric energy which can be used by load and charge of Li battery.The major focus of this paper is the characteristics and the technique of self-adaptation inversion type wave energy generator device.According to the research of many kinds of wave energy generator devices' energy conversion and storage methods,this paper referred to the technique of wind energy which is similar with the wave energy,and then offered a method of the electron circuit which is different from the traditional mechanical method for energy conversion and stabilizing system.Besides,refer to the electrical energy characteristics of the devices,the energy conversion and energy storage system were designed.Some innovation work was done in this paper:1.It provided a new solution for energy conversion and stabilizing system of the micro wave energy generator.That is to use mechanical direct drive method to make the permanent magnet DC generator work.Besides,a reducer was used to make the device's rotating speed fit the generator's.Meantime,a filter and voltage regulation electric circuit with super capacitors was used to stabilize the voltage,so that it can provide the back-end load with the electric energy which can be used and saved.2.It noticed a micro wave energy matching method which can make the back-end power to be suitable as the front-end wave energy generator output power.It is realized by testing the power and voltage of the main parts of the system and controlling the number of the batteries which are charged in the system.Meanwhile,according to the features of the power generated by the device and the Li battery's charging characteristics,it regulated the parameter of filter and voltage regulation circuit.Thus,the various parts of energy conversion system can match with each others.3.It gave a micro wave energy storage method.According to the high mobility of the micro wave energy generator device,Li battery storage method was used to replace the traditional method which is convey the power to the electrified wire netting directly,because it is efficient,environmental-friendly and small-sized.Also,the method's feasibility was verified through the experiment.According to the experiment,on the present circumstance,an optimal parameters group was gotten(±15°maximum blade angle,25? resistance and 1.5s period),which can obtain the maximal value of the power(nearly 4W).And on the condition that the device's output voltage fluctuates within 10 V and the average power is around4 W,the charging voltage is the most stable when the stabilizing value of the circuit is6 V and the current-limiting resistance is 25?.The stable charging voltage is propitious to the batteries' life. |
