A friction piezoelectric electromagnetic combined type magnetic energy collecting device comprises a shell, a top cover is arranged at the top of the shell, a base is arranged in the shell, a cantilever beam is fixed above the base, a permanent magnet is arranged at the end of the cantilever beam, a piezoelectric material is arranged on the upper surface of the cantilever beam, and a first friction layer is arranged on the lower surface of the cantilever beam. An acrylic plate is arranged on the upper surface of the base, a third friction layer is arranged on the acrylic plate, and a second friction layer is arranged on the third friction layer; and a coil is arranged on the top cover. Efficient utilization of energy is achieved by converting weak magnetic energy into mechanical energy andthen converting the mechanical energy into electric energy. Energy can be supplied to low-power-consumption components in a power system. After output of the device is subjected to full-bridge rectification, direct current output can be provided for portable and small sensors so as to be used by component equipment. The self-powered clean energy system has huge application potential.
Description
technical field [0001] The invention relates to a magnetic energy collection device, in particular to a friction-piezoelectric-electromagnetic composite magnetic energy collection device. Background technique [0002] With the advent of Industry 4.0, the Internet of Things technology plays a key role in collecting and analyzing information, realizing environmental monitoring, public safety and other related aspects, and has increasingly broad application prospects in the intelligentization of power systems. [0003] At this stage, the Internet of Things technology mostly adopts wireless sensor networks, using a large number of wireless sensor nodes to build a network through self-organization, and perceive real-time information in the surrounding environment through the sensors in the network, and then analyze and process the signals and then pass them on to the observers. By. This technology is widely used in intelligent systems and power system real-time monitoring and ot...
