Even the engineering special vehicle has low utilization rate of a power system, and a part of energy of mechanical power is converted into hydraulic power through a power takeoff and a hydraulic system and is used for self-unloading of a cargo compartment of the vehicle. Some special vehicles adopt a full-power takeoff, most of power of the vehicles can be taken out, and the power is converted into hydraulic power through a hydraulic system, so that power is provided for special equipment. However, the hydraulic power system has a weak point that a hydraulic pump, a hydraulic motor, a control valve, a hydraulic oil tank, an oil outlet pipe, an oil return pipe and other parts need to be arranged to realize a hydraulic power transmission function, and the power transmission distance is greatly limited and generally does not exceed 50 meters. Therefore, it is necessary to develop a device that can take out most of the mechanical power of the vehicle through a full-power takeoff, and transmit the taken-out power to a generator through a transmission system, and the generator converts the mechanical energy into electric energy.
