Abstract

The invention discloses a multi-layer pressure driving type air pressure energy converter used for collecting energy of a pneumatic system, the air pressure energy converter comprises a base assembly, a base assembly, an end cover and a bolt assembly, and the base assembly is installed between the base assembly and the end cover through the bolt assembly. The invention provides a multi-layer pressure driving type air pressure energy converter for collecting energy of a pneumatic system based on the direct piezoelectric effect of a piezoelectric material. Due to the special flow channel design and the synchronous superposition of the multiple layers of power generation units, the power generation efficiency of the pressure driving type air pressure energy converter is higher, the space structure of a prototype is more compact, and the application range is wider. According to the energy converter designed by the invention, the maximum utilization of pneumatic energy can be realized, the efficient energy collection of piezoelectric power generation materials is realized in a limited space, and reference is provided for the energy supply problem of a sensor in a pneumatic system.

Description

technical field [0001] The invention belongs to the field of energy collection, and relates to a multi-layer pressure-driven air pressure energy converter used for energy collection of a pneumatic system. Background technique [0002] The current research on collecting and converting natural energy into electrical energy by means of photovoltaics, static electricity, and piezoelectricity has penetrated into many fields. For example, photovoltaic battery on-board charging devices can convert light energy into electrical energy and store it in the battery to prolong the life of the battery. recharge mileage. However, the energy density of the battery in the prior art is limited, and it cannot supply power for a long time, which brings about the problem that the wireless sensor needs to be replaced frequently. [0003] Piezoelectric materials have the advantages of high energy conversion efficiency, simple device structure, no electromagnetic interference, and long service lif...
