Abstract

The invention provides a friction nanometer generator. The generator comprises: a planet carrier of which the one end is provided with a transmission shaft and the other end extends out to form a plurality of output shafts; multiple pin rollers, wherein the multiple output shafts are sleeved with the multiple pin rollers through bearings respectively, and a friction layer is arranged on the surface of each pin roller; and a stator which is arranged outside the multiple pin rollers in a sleeving manner, wherein an electrode unit is arranged on the inner wall of the stator, so that each pin roller can be in rolling friction contact with the electrode unit. The invention also provides a self-driven intelligent tachymeter based on the friction nanometer generator.

Description

technical field [0001] The present disclosure relates to the field of energy supply / sensing technology, in particular to a friction nanogenerator and a self-driven intelligent speedometer based on it. Background technique [0002] As widely distributed renewable energy, wind energy and water energy play an increasingly important role in the process of power supply and response to energy crisis. For example, according to statistical data, the global wind resource reserves are abundant, of which the mineable part reaches 5.3×10 13 kWh. Take the anemometer as an example. As an important wind speed monitoring device, the anemometer often works in an unattended harsh environment and requires continuous and reliable long-term energy supply. Up to now, anemometers are mainly powered by batteries with limited life, which greatly increases maintenance costs and environmental pollution. Therefore, capturing wind energy from the working environment to power the anemometer is an opti...
