The invention discloses a low-noise on-vehicle power station which comprises an on-vehicle system comprising a vehicle chassis and a wagon box, a diesel generator unit, a control and operation system, a wire lead-out cable system, a wind inlet silencing device, a wind exhaust silencing device and an air exhaust silencing device, wherein the diesel generator unit comprises a machine set pedestal, a diesel engine, a generator, a cooling water tank and an air exhaust pipe. The front part, the middle part and the rear part of the wagon box are respectively a silencer chamber, a machine unit cabinet for installing the diesel generator unit and a manipulating chamber for installing the control and operation system. A wind inlet end and a wind exhaust end of the diesel generator unit are respectively positioned at the rear part and the front part of the machine unit cabinet. The wind inlet silencing device comprises a case sound-isolating baffle and a pair of air inlet sound-isolating baffles. The wind exhaust silencing device comprises a flare opening, a group of sheet-type silencers and a pair of wind exhaust sound-isolating baffles. The air exhaust silencing device comprises a corrugated damping joint, a resistance silencer and a resistance silencer. The noise of the low-noise on-vehicle power station is around 75dB (A) so that the problem that of the noise disturbs residents is solved.
Description
A low-noise vehicle-mounted power station technical field The invention relates to an emergency backup power supply, in particular to a low-noise vehicle-mounted power station. Background technique The vehicle-mounted power station is used as a mobile emergency backup power supply in places such as electric power, communications, engineering rescue, and military where power failures will have serious impacts. Traditional vehicle-mounted power stations can only achieve mobile emergency power supply, but the exhaust noise, mechanical noise and combustion noise of the diesel generator set during power supply have become a puzzling problem. The noise of a general diesel generator set is around 110dB(A) when it is working. If the necessary noise reduction measures are not taken, the vibration and exhaust noise during unit operation will cause serious damage to the surrounding environment. Contents of the invention The purpose of the present invention is to overcome the def...
