Embodiment 1
[0026] Such as figure 1 and figure 2 As shown, this embodiment provides a multi-stage energy storage device, including an energy storage cylinder, a hydraulic motor 17, a fuel tank 16, a rotary generator 1 and a linear generator 2;
[0027] The energy storage cylinder includes a closed cylinder body. The closed cylinder body is composed of a cylinder bottom 4, a cylinder barrel 5 and a cylinder head 6 connected in sequence. One end of the cylinder head 6 is provided with an elastic moving device, and one end of the cylinder bottom 4 is provided with an energy transmission device. There is a repulsive magnetic force between the device and the energy transfer device, and hydraulic oil is filled in the cylinder 5 between the elastic moving device and the energy transfer device;
[0028] The airtight cylinder body, the hydraulic motor 17 and the oil tank 16 are connected through an oil circuit to form a hydraulic circuit, the hydraulic motor 17 is connected to the rotary generat...
Embodiment 2
[0035] A multi-stage energy storage device, the structure of which is as described in Embodiment 1, the difference is that a limit block 24 is also provided in the cylinder 5, and the limit block 24 is located between the partition plate 23 and the piston permanent magnet 25 and further The oil port 10 and the oil outlet 11 are located between the limiting block 24 and the separator 23 . The limit block can block the stroke of the piston permanent magnet, preventing the piston permanent magnet from exceeding the set thread.
Embodiment 3
[0037] A working method of the multi-stage energy storage device as described in Embodiment 2, specifically comprising the following steps,
[0038] When an impacting object touches the piston rod head 9, the piston rod 8 moves and drives the piston 26 to move accordingly, the piston 26 squeezes the hydraulic oil to generate pressure on the hydraulic oil, and the return spring 7 is compressed at the same time; The oil port 11 and the oil outlet check valve 12 enter the hydraulic motor 17, the hydraulic motor 17 starts and drives the flywheel 19 to rotate, while the flywheel 19 rotates and drives the rotary generator 1 to run and generate electricity; the piston 26 squeezes the hydraulic oil gradually to the permanent magnet at the bottom of the cylinder During the movement of 25, the repulsion force between the piston permanent magnet 25 and the cylinder bottom permanent magnet 21 is getting bigger and bigger. When the repulsion force is greater than the friction force between ...
