A key (or crown) you wind to add energy. A spiral spring to store the energy you add with the key. (Pendulum clocks store energy with weights that rise and fall, but other clocks and windup wristwatches use springs instead.) A set of gears through which the spring''s energy is released.
With the elastic energy storage–electric power generation system, grid electrical energy can drive electric motors to wind up a spiral spring group to store energy when power grid is adequate, and the stored energy can drive electric generators to generate electrical energy when power grid is insufficient. The working principle is shown in Fig. 2.
Spiral spring is the most common elastic energy storage device in practical applications. Humanity has developed various types of elastic energy storage devices, such as helical springs, disc springs, leaf springs, and spiral springs, of which the spiral spring is the most frequently-used device. Spiral springs are wound from steel strips [19, 20].
