Abstract

The invention provides an impulse-type bionic power device based on a single-component fuel. The device mainly consists of a fuel supply system and an impulse-type reaction system, wherein the fuel supply system is used for realizing storage and flow regulation and control of single-component fuels; the single-component fuels sequentially pass through an inlet high-frequency switch valve and a catalyst bed of the impulse-type reaction system and are decomposed from a liquid state into a gas state under the action of a catalyst, so that the internal pressure of the catalyst bed increases rapidly; the whole process can be divided into three stages, namely an input stage, a reaction stage and a spraying stage; during the input stage, the inlet high-frequency switch valve is opened, and an outlet high-frequency switch valve is closed; during the reaction stage, the inlet high-frequency switch valve and the outlet high-frequency switch valve are closed; during the spraying stage, the outlet high-frequency switch valve is opened, and the inlet high-frequency switch valve is closed. The device is capable of obtaining the flow of a flow pump and parameter values such as PWM control signal duty ratio of the inlet high-frequency switch valve and the outlet high-frequency switch valve by use of formulae of thermodynamics and hydromechanics according to the output force requirement, and generating a continuous impulse spraying effect. The impulse-type bionic power device has the advantages of high power density, environmental friendliness, simple structure, high efficiency and the like, and is applicable to power systems of devices such as exoskeleton robots and jet packs.

Description

technical field [0001] The invention relates to a pulse type bionic power device based on monocomponent fuel and a control method thereof, which are suitable for exoskeleton robots and jet pack power devices. Background technique [0002] Exoskeleton robots can follow the movement of the human body and bear the main load, thereby enhancing the functions of the human body, and jetpacks are one of the effective ways to realize human flight and motion assistance. In order to achieve energy autonomy and improve the practical level, exoskeleton robots and jetpacks represented by HAL-5, BULC, XOS, BLEEX, Jetpack, and Martin generally use batteries and gasoline engines as power to drive motors or hydraulic drive systems. Among them, lithium battery is the most widely used form of power, and its relatively low energy density limits its long-term use; fuel cell technology continues to develop and has high energy density and power density, but the high cost and harmful substrate mater...
