A large scroll spring energy storage device

Abstract

The invention discloses a large scroll spring energy storage device, which comprises a plurality of scroll spring energy storage boxes, left and right box covers, a base and a foundation plane; each scroll spring energy storage box includes a mandrel, an energy storage box shell And multiple single-module coil springs including outer ring fixing plate, mandrel sleeve, volute spring and left and right cover plates; the outer end of the worm spring is fixed on the inner wall of the outer ring fixing plate, and the inner end is fixed on the outer wall of the mandrel sleeve Above; the left and right cover plates are rotatably fixed on the mandrel sleeve, and their outer circles are fixed together with the outer ring fixing plate; each single-module worm spring is worn on the mandrel, and its outer ring fixing plate is clamped and fixed on the On the inner wall of the energy storage box shell; the left and right box covers are rotatably fixed on the left and right ends of the mandrel shafts of the left and right volute spring energy storage boxes, and their outer circles are fixed together with the energy storage box shell; the adjacent The energy storage box shells of the volute spring energy storage box are fixed together. The volute spring of the present invention is simple and convenient to install, maintain, maintain and replace, the mandrel shaft is not easily bent and deformed, the energy storage and release are good, and the service life is long.

Description

technical field [0001] The invention belongs to the field of physical energy storage, and relates to a mechanical elastic energy storage device, in particular to a large scroll spring energy storage device. Background technique [0002] The large scroll spring energy storage box is a mechanical elastic energy storage device, which belongs to a new type of physical energy storage technology, and uses a large planar coil spring as an energy storage component. The planar volute spring is formed by a group of reeds with a rectangular cross-section coiled in a plane. At present, the installation of the coil spring is to install one or more coil springs in the energy storage box, one end of the coil spring is installed on the inner wall of the energy storage box, and the other end is installed on the mandrel. The planar volute spring is used as an energy storage structure. When storing energy, the volute spring is tightened to store elastic potential energy; when releasing energy...

AI Technical Summary

Problems solved by technology

Due to the structural size of the large scroll spring energy storage box, the self-weight is very large

When connecting in series, the mandrels of the two coil spring energy storage boxes are segmented, so that each coil spring energy storage box is structurally equivalent to a cantilever beam structure. During long-term operation, the coil spring energy storage box The mandrel of the body is prone to bending deformation, and the eccentricity of the volute spring energy storage box will cause the eccentricity of the energy storage box during operation. The entire energy storage structure will vibrate during operation, which seriously affects the energy storage of the volute spring. The energy storage and energy release process of the box greatly reduces the service life of the large scroll spring energy storage box

Moreover, the structural size, mass and bending moment of large planar coil springs are very large. When multiple coil spring energy storage boxes are connected in series and multiple groups of coil springs are installed in parallel, it is very difficult to install each coil spring. , more difficult to maintain and replace
