Multistage coil spring energy storage and release management device

Abstract

The invention provides a multistage coil spring energy storage and release management device. The device comprises a plurality of coil spring energy storage units and an energy release management andcontrol unit; each coil spring energy storage unit comprises a coil spring, a pulley and a sleeve, wherein the pulley and the sleeve are coaxial and are fixed, the pulley is provided with a hollow structure, the coil spring is arranged in the pulley, the end of a coil spring outer ring is fixed with the pulley, wherein the sleeve of the coil spring energy storage unit at the uppermost part sleeveson a middle column, the end of a coil spring inner ring is fixed with the middle column, the sleeves of the rest coil spring energy storage units sleeve the sleeves of the above adjacent coil springenergy storage units, the end of the coil spring inner ring of each coil spring energy storage unit is fixed with sleeves of the above adjacent coil spring energy storage units, and a power piece is arranged on the pulley of each coil spring energy storage unit. According to the multistage coil spring energy storage and release management device, multistage storage and release of energy can be realized, and effective management of energy is achieved.

Description

technical field [0001] The invention relates to the technical field of coil spring energy storage, in particular to a multi-stage coil spring energy storage and release management device. Background technique [0002] Due to people's urgent demand for energy, it has strong temporal and spatial characteristics. In order to use energy reasonably and improve the utilization rate of energy, it is necessary to use a device to collect and store the excess energy that is temporarily not used for a period of time, and then release it when it needs to be used, or transport it to places where energy is scarce. Use, therefore, requires an energy storage device with regard to energy storage and release management; [0003] The most commonly used energy storage device today is an electrical storage device, ie a battery. It stores energy electrochemically, and the charging and discharging process is a chemical reaction. However, lead-acid batteries will produce toxic and harmful heavy ...

AI Technical Summary

Problems solved by technology

If the stiffness coefficient is small, the flexibility is good, the deformation range is large, and it is easy to control the accuracy of energy storage, but the stored energy is less

If the stubbornness coefficient is large, the rigidity is large and the deformation range is small, it is difficult to accurately control the output of energy storage, but the energy storage ability is strong

Therefore, a single scroll spring accumulator cannot take into account both the storage capacity and the storage accuracy, and cannot achieve multi-level storage and release of energy, lacking energy management

Using a single scroll spring to work for a long time will cause fatigue, permanent deformation, weakening or even disappearing of the elastic force
