  • Device for applying in a pavement for collecting mechanical energy from vehicles passing over for generating electricity
    Patent number: 10954926
    Abstract: Device for applying in a pavement for collecting mechanical energy from a vehicle passing over said pavement for actuating an electromechanical converter for generating electrical energy, said device comprising: an electromechanical converter; a mechanical or mechanical-hydraulic system comprising a crank-linear slide or crank-piston; a base structure for supporting and fixing the device to the pavement; a cover displaceable in vertical axis translation caused by the vehicle passing over, wherein the cover is arranged to actuate the crank-linear slide or crank-piston; a rack-pinion, or a hydraulic cylinder and respective hydraulic circuit having actuator, arranged for converting linear displacement of the linear slide or the piston, respectively, into rotation of a shaft of the electromechanical converter; wherein said cover has a non-horizontal surface profile having a first elevation at a first end and a second elevation at a second end, wherein the first elevation is lower than the second elevation.
