Abstract

The invention relates to an energy conversion device, in particular to a rotating wheel non-contact excitation type fluid kinetic energy conversion device. The device solves the problems that an existing fluid kinetic energy conversion device cannot easily adapt to a complex fluid environment, and is complex in mechanical structure, low in energy harvesting efficiency, hard to become micro or portable, prone to structural fatigue failure and short in service life. The device comprises a rotating wheel, two fixing bases, two rotating shafts, 2N excited magnet pieces and 2N excitation magnet pieces. The rotating wheel comprises a supporting shaft frame and N wheel plates. Each fixing base comprises a cylindrical housing, a hubbed flange base and N piezoelectric composite cantilever beams. Each piezoelectric composite cantilever beam comprises an elastic metal plate and two piezoelectric ceramic plates. The cylinder wall of the cylindrical housing and the base plate of the hubbed flange base of each fixing base are connected into a whole. The rotating wheel non-contact excitation type fluid kinetic energy conversion device is used in the field of new energy power generation.

Description

technical field [0001] The invention relates to an energy conversion device, which belongs to the field of new energy power generation devices. Background technique [0002] With the rapid development of integrated circuit design and manufacturing technology, the miniaturization and miniaturization of electronic components has become a trend, and low energy consumption design technology has also made the power consumption of these electronic components smaller and smaller. As a typical example of this type of electronic components, wireless sensors are commonly found in electromechanical systems such as modern logistics equipment, flexible production lines, and signal transfer stations. They are especially common in occasions where the environment is relatively complex and unsuitable for manual operation. The energy supply requirements of such devices are The system is stable, reliable, and low in installation and maintenance costs. The low-energy power supply of traditiona...
