Problems solved by technology

The scattered energy in life is mainly the scattered kinetic energy generated by human activities, which has the characteristics of discontinuity and instability. If these scattered kinetic energy are directly used for electric energy conversion, there will be many shortcomings, such as directly acting on piezoelectric materials. The conversion efficiency is low, and it is difficult to reach the required speed for power generation directly on the generator, and the power generation voltage is unstable, etc.

Abstract

A potential energy storage type device for collecting and storing scattered energy comprises an energy input shaft, wherein the energy input shaft is connected with a front half shaft by a retarding mechanism and the front half shaft is connected with a rear half shaft by a clutch. The rear half shaft is connected with a potential energy storage unit which is used for receiving the kinetic energy acquired by the rear half shaft and transforming the kinetic energy to the potential energy to store. An energy transformation control system is arranged inside the clutch to control the clutch actions. The potential energy storage type device has the advantages that, according to the law of the conservation of mechanical energy, scattered kinetic energy can be transformed to potential energy for storage temporarily; when the kinetic energy accumulates to a certain extent, constant and stable kinetic energy is released to drive an electric energy transducer. Compared with using flywheels as an energy storage unit, the potential energy storage type device is capable of realizing long-hour energy storage; while compared with the energy collecting mode of electricity generation, defects of electricity generation can be avoided so as to significantly improve the energy efficiency and the stability of generating capacity.

Description

technical field [0001] The present invention relates to the technical field of energy picking (energy harvesting). Specifically, it relates to a potential energy storage type scattered energy collecting device for collecting and storing scattered energy. Background technique [0002] Human beings will generate a lot of scattered energy in their daily life, such as opening and closing doors, exercising and fitness, etc. will generate a certain amount of mechanical energy. Under the current international situation of energy shortage, many countries are actively developing technologies for recycling (energy picking) for these scattered energies. At present, the scattered energy collection technology mainly utilizes the piezoelectric effect of certain materials, or converts them into electrical energy for storage and use through a generator. The scattered energy in life is mainly the scattered kinetic energy generated by human activities, which has the characteristics of disc...
