Description

Electric device based on clockwork spring engine

Technical Field

The utility model belongs to the technical field of the clockwork spring engine, especially, relate to an electric actuator based on clockwork spring engine.

Background

Various energies exist in nature, such as air and water flowing around us and small molecular motion in organisms, but the energies are often converted into corresponding potential energies to realize storage. If wind energy or running water is converted into electric energy, the electric energy is further converted into chemical energy by using a storage battery for storage, and the chemical energy is converted into the electric energy and further converted into mechanical energy when required. It is evident that the efficiency of such multi-step energy storage and release is often low. In many cases, people can also convert the work (mechanical energy) which is done by the outside into elastic energy and store the elastic energy. Such as various spring devices, springs for toys and clocks. This conversion between mechanical and elastic energy is achieved by a change in the inter-atomic distance within the spring material. That is, when an external force is applied to the spring, the interatomic distance of the spring material is lengthened or shortened, thereby converting the work performed by the external force into the elastic energy of the spring; when the spring is released, the interatomic distance inside the spring material is restored to the original distance, so that the elastic energy is released as work to the outside. Although the conversion between mechanical and elastic energy can be made with little loss, the energy that can be stored by an elastically deformable material is of relatively low density.

With the research on the nano spring in east Dingdong, the university of West's traffic, etc., a new device, namely the nano spring, which takes surface energy as a medium and efficiently stores and releases mechanical energy is designed. Unlike bulk springs, nanosprings achieve the storage and release of energy through the reconstruction of surface atoms. The device behaves like an accordion during loading and unloading: in the loading process, the twin crystal boundary moves to the twin crystal orientation with high surface energy, so that the work done by external force is converted into the surface energy of the nano device and stored; upon unloading, the twin boundaries move to a lower twin orientation at the surface driven by the stored surface energy, converting the stored surface energy from surface to mechanical energy. The nano spring has the performance which is obviously superior to that of a block spring. Taking the nano spring with the cross section width of 2.3nm as an example, the stored energy density is over 1000J/cm3. (more than 1600 times of a clock spring), and the energy conversion efficiency is as high as 98%, the energy conversion efficiency of the device is reduced along with the increase of the cross section width of the spring, but the energy conversion efficiency can still be kept more than 95% under the condition that the cross section width of the nanowire is not more than 5 nm.

Therefore, the nano spring can be expected to play a great role in the field of energy conversion in the near future, and particularly in the technical field of engines, the nano spring is expected to replace traditional engines (such as an internal combustion engine, an external combustion engine, a motor and the like) and storage batteries. It has been proposed in the related art to construct a clockwork spring generator using a nano-spring. However, the clockwork generator has problems in configuration and use, and other auxiliary components are required for performance optimization. For example, a spring motor is proposed in patent CN108301994A, which realizes efficient conversion of stored energy of a spring; and the transmission case is arranged on the main power output shaft to control the displacement conversion of the whole engine, but the whole output is driven by machinery, the resistance between gears is large, and the speed raising is slow.
