Problems solved by technology

Although this energy harvesting method has high efficiency, it must have a vibration source of mechanical vibration to play its role.
In some special cases, it is difficult to find an effective vibration source to supply wireless communication equipment, such as remote places such as deserted islands and uninhabited mountains, which brings inconvenience to sending out distress signals and timely contact with the outside world.

Abstract

The invention discloses an energy collecting device and an energy collecting method. The device comprises a fixing base (1) and a support (2) arranged on the fixing base (1), the support (2) is provided with a rotation wheel (3), the rotation shaft (5) of the rotation wheel (3) is provided with projections (4), one side or two sides of the rotation shaft (5) are provided with cantilever beams (6), the other ends of the cantilever beams (6) are fixed on the fixing base (1), and the surfaces of the cantilever beams (6) are provided with piezoelectric patches (7). According to the invention, rotational energy is converted into mechanical oscillation energy, electric energy is generated, and then power is supplies to a sensor or other low-loss systems, such that restrictions of a vibration source are eliminated, and the application is convenient.

Description

technical field [0001] The invention relates to an energy collection device and a collection method, in particular to an energy collection device and a collection method capable of utilizing wind energy and water energy. Background technique [0002] In recent years, with the wide application of wireless devices, their power supply issues have received widespread attention. As a new type of miniature power generation device, piezoelectric energy harvesting device has the advantages of simple structure, low calorific value, no electromagnetic interference, easy processing and production, and realizes structural miniaturization and integration. It is suitable for various sensing and monitoring system. Most of the piezoelectric energy harvesting devices on the market are completed by the transfer of mechanical energy around them. Although this energy collection method has high efficiency, it must have a vibration source of mechanical vibration to play its role. In some speci...
