The invention provides an electric cleaning and sweeping vehicle and a power coupling device thereof, thereby solvingtechnical problems that in the prior art, a motor of an electric cleaning and sweeping vehicle is low in utilization efficiency, the weight of a single motor is large, and cost is high. The power coupling device of an electric cleaning and sweeping vehicle comprises a housing, a walking power input shaft, an operation power input shaft, a walking power output shaft and an operation power output shaft, whereinthe walking power input shaft, the operation power input shaft, the walking power output shaft and the operation power output shaft are installed on the housing. A gear shifting mechanism and a planet row mechanism are arranged in the housing. The gear shifting mechanismis in transmission connection with the walking power input shaft; a gear ring serves as an output component of the planet row mechanism, and the gear shifting mechanism and the planet row mechanism are in transmission connection with the walking power output shaft; a planet row combination sleeve is further installed in the housingand used for locking or unlocking a planet carrier of the planet row mechanism relative to the housing, and a clutch is arranged on a transmission branch between the operation power output shaft and the operation power input shaft.
