1. An energy storage device, comprising a mounting seat, a first spring energy storage component, a second spring energy storage component, a one-way limiter, a transmission component, and a generator;
the first spring energy storage component comprises a first rotating shaft, a first spring, and a first spring barrel; the first rotating shaft is rotatably mounted in one direction on the mounting seat; the first spring is sleeved on the first rotating shaft; the first spring barrel is covered on the first spring; the inner end of the first spring is connected to the first rotating shaft, and the outer end thereof is connected to the first spring barrel; the first spring barrel is rotatably mounted on the mounting seat; rotate the first rotating shaft to wind up the first spring; the first spring drives the first spring barrel to rotate;
the second spring energy storage component comprises a second rotating shaft, a second spring, and a second spring barrel; the second rotating shaft is rotatably mounted in one direction on the mounting seat; the second spring is sleeved on the second rotating shaft; the second spring barrel is covered on the second spring; the inner end of the second spring is connected to the second rotating shaft, and the outer end thereof is connected to the second spring barrel; the second spring barrel is rotatably mounted on the mounting seat; rotate the second rotating shaft to wind up the second spring; the second spring drives the second spring barrel to rotate;
the one-way limiter is arranged on the mounting seat; the one-way limiter is configured for that when the stored energy of the first spring is greater than the stored energy of the second spring, the one-way limiter fixes the second spring barrel, and when the stored energy of the second spring is greater than the stored energy of the first spring, the one-way limiter fixes the first spring barrel;
the first spring barrel and the second spring barrel are both connected to the transmission component and drive a motor shaft of the generator to rotate through the transmission component.
