meanwhile, the combination of double-motor and coaxial-drive is adopted, when the double-motor double-shaft double-motor double-shaft double-motor driving device is driven, one motor 23 is damaged, the other motor drives the device to return, and at the moment, the sleeve 38 and the middle shaft 5 are mutually limited and guided, the stability is better, and the work is more stable by matching with the rotation of the double-motor double-shaft and can resist the turbulent airflow in a fire scene;

meanwhile, the fan 2 is arranged for cooling the internal motor 23, and air can flow through the storage battery 14 through the bypass pipe 22 to cool the storage battery, so that the working stability of the device under the high-temperature condition is ensured.

The self-cleaning type water taking device is reasonable in structural design, high in precision, the unmanned mechanism is matched with self-cleaning imaging equipment, the fire is stably extinguished in a dangerous environment, the safety of rescue workers is guaranteed to the maximum extent, the volume of the water taking device is variable, the water taking volume is convenient to control and advance control, the double-engine coaxial combination is adopted, the fault tolerance rate is higher, the self-cooling system is matched, and the use is safer.
