Wherein, pulsed power source module includes: a cam link mechanism consisting of a second connecting rod 3 and a cam 4, a plunger cylinder 5, a one-way throttle valve 6, a spring 7, a piston cylinder 8, a one-way valve A9, a one-way valve B10, a filter 11, a pilot-operated overflow valve 13, a damper 14 and a two-position two-way electromagnetic directional valve 15. And, the continuous power supply module includes: a two-position three-way electromagnetic directional valve 16, an energy accumulator 17, a two-position three-way electromagnetic directional valve 18 and an energy accumulator 19. And, the power generation module includes: speed regulating valve 20, quantitative motor 21, coupling 22, generator 23, cooler 24 and filter 25.
Further, as shown in fig. 1 and 2, in the pulse type power source module, a form that 8 plunger cylinders are connected in parallel with 8 piston cylinders is adopted, so that when a vehicle frequently passes through the speed bump 1, kinetic energy generated by vehicle vibration can be efficiently recovered.
In addition, according to the hydraulic power generation deceleration strip device, when a vehicle passes through the deceleration strip 1, the deceleration strip 1 moves downwards, the pulse pump is driven to work through the connecting rod mechanism, the length of the extending plunger of the plunger cylinder 5 of the pulse pump is different, the piston in the piston cylinder 8 is driven to move, and oil discharge or oil absorption of a rodless cavity of the piston cylinder 8 is controlled. A plunger cylinder 5 of the pulse type power source module is connected with an oil inlet of a one-way throttle valve 6; an oil outlet of the one-way throttle valve 6 is connected with a rod cavity of the piston cylinder 8; an oil inlet of the oil suction filter 11 is connected with an oil tank, and an oil outlet is connected with oil inlets of the check valves A9; the oil outlet of each check valve A9 is connected with the rodless cavity of each piston cylinder 8; the piston cylinder 8 adopts a spring to automatically reset; the rodless cavity of each piston cylinder 8 is connected with the oil inlet of each check valve B10; the oil outlets of the check valves B10 are respectively connected with the valve front oil inlets of the pilot-operated overflow valve 13, the two-position three-way electromagnetic directional valve 16 and the two-position three-way electromagnetic directional valve 18; an oil outlet of the pilot overflow valve 13 returns to an oil tank; a control oil port of the pilot overflow valve 13 is connected with an oil inlet of the damper 14; an oil outlet of the damper 14 is connected with a valve oil inlet of a two-position two-way electromagnetic directional valve 15; the valve rear oil outlet of the two-position two-way electromagnetic directional valve 15 is connected back to the oil tank.

When the pressure in the energy accumulator 19 reaches a critical value, the two-position three-way electromagnetic directional valve 16 is powered on, the two-position three-way electromagnetic directional valve 18 is powered off, high-pressure oil in the energy accumulator 19 flows through the speed regulating valve 20 through the two-position three-way electromagnetic directional valve 18 and then flows into the quantitative motor 21, the motor 21 outputs a constant rotating speed and transmits the constant rotating speed to the generator for power generation, and the energy accumulator 17 replaces the position of the energy accumulator 19 to continuously receive the oil pressed in by the hydraulic cylinder.
