Abstract

FIELD: electric engineering. SUBSTANCE: device has piezoelectric elements and unit which performs their mechanical load and which is designed as cylinder with or without end disks and drive for cylinder rotation around its longitudinal axis. Piezoelectric elements are designed as piezoelectric strips which are located on outer surface of cylinder along its envelope. Spaces between piezoelectric strips are filled with dielectric material. Strips are attached to cross ribs which bulges over surface of cylinder. Device may be used for conversion of mechanical energy of moving gases and liquids to electric power. EFFECT: increased efficiency, decreased weight and size. 1 dwg

Изобретение относится к пьезоэлектрическим генераторам и может быть применено для преобразования механической энергии движущихся газов и жидкостей в электрическую энергию, позволяет повысить величину удельной механической энергии, воздействующей на пьезоэлементы генератора, уменьшить массогабаритные параметры устройства. Пьезогенератор содержит пьезоэлементы и систему их механического нагружения. Новым является то, что система механического нагружения пьезоэлементов выполнена в виде цилиндра с торцевыми дисками или без них и приводом для вращения цилиндра вокруг его продольной оси, а пьезоэлементы выполнены в виде полосок пьезоматериала, размещенных на наружной поверхности цилиндра по его образующей с промежутками между полосками, заполненными диэлектрическим материалом, при этом пьезоматериал закреплен к поперечным ребрам, выступающим над наружной поверхностью цилиндра.The invention relates to piezoelectric generators and can be used to convert the mechanical energy of moving gases and liquids into electrical energy, allows to increase the specific mechanical energy acting on the piezoelectric elements of the generator, to reduce the overall dimensions of the device. The piezoelectric generator contains piezoelectric elements and a system of their mechanical loading. New is that the system of mechanical loading of the piezoelectric elements is made in the form of a cylinder with or without end disks and a drive for rotating the cylinder around its longitudinal axis, and the piezoelectric elements are made in the form of strips of piezoelectric material placed on the outer surface of the cylinder along its generatrix with gaps between the strips, filled with dielectric material, while the piezomaterial is fixed to the transverse ribs protruding above the outer surface of the cylinder.
