The invention discloses a self-traveling dry self-sucking emergency flood drainage, fire fighting and power generation integrated device which comprises a generator, a self-sucking pipeline, a vacuum breaking valve, a powerful self-sucking device, a left water tank, a right water tank, an elastomer cam rotor pump, a fuel tank chassis, a vacuum pump, a vacuum pump outlet, a motor, wheels, a diesel engine, an electromagnetic clutch, a first synchronous pulley, a second synchronous pulley, a speed reducer, a clutch, a traveling shaft, a belt and a driving axle. The device disclosed by the invention can realize self-traveling and can move by adopting a mode of synchronous belt drive-speed reducer-clutch-traveling shaft-driving axle, thereby reducing the operating difficulty; the device can realize dry self-sucking, and the elastomer cam pump still has a self-sucking function even if the elastomer cam pump is worn; and the device can realize self-sucking flood drainage, and the water flow can be applied to power generation.
