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

The invention discloses a large volute spring energy storage device comprising a plurality of volute spring energy storage boxes, a left box cover, a right box cover, a base and a basic plane. Each volute spring energy storage box comprises a core shaft, an energy storage box shell and a plurality of single-module volute springs comprising outer circle fixing plates, core shaft sleeves,volute springs, left cover plates and right cover plates. The outer ends of the volute springs are fixed to the inner walls of the outer circle fixing plates, and the inner ends of the volute springs are fixed to the outer walls of the core shaft sleeves. The left cover plates and the right cover plates are rotatably fixed to the core shaft sleeves, and the outer circles of the left cover plates and the right cover plates and the outer circle fixing plates are fixed together. Each single-module volute spring is arranged on the corresponding core shaft in a penetrated mode, and the outer circle fixing plates of the single-module volute springs are fixed to the inner walls of the energy storage box shells in a clamped mode. The left box cover and the right box cover are rotatably fixed to the left endof the core shaft of the left volute spring energy storage box and the right end of the core shaft of the right volute spring energy storage box respectively, and the outer circles of the left box cover and the right box cover and the energy storage box shells are fixed together. The energy storage box shells of the adjacent volute energy storage boxes are fixed together. According to the large volute spring energy storage device, the volute springs can be mounted, maintained and replaced easily and conveniently; the core shafts are not liable to be bent and deformed; and the performance of energy storage and release is 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...
