[0027] The use method and advantages of the present invention: When the power-assisted hose retracting and releasing vehicle is in use, the working process is as follows:

[0028] When the water hose is retracted, the locking pin 13 is removed from the protruding rod 12 and the corresponding rotating frame 9. At this time, the wheel 6 is in a free state. One end of the water hose is fixed to one of the rotating rods 10, and the motor 4 is started to work. The battery 2 provides power to the motor 4. The motor 4 drives the rotating shaft 8 to rotate through the reducer 5, so that the rotating shaft 8 drives the rotating frame 9 to rotate, and then the rotating frame 9 drives the two rotating rods 10 to rotate, so as to realize the reeling of the water hose, saving time and effort. After the water hose is reeled, the protruding rod 12 and the corresponding rotating frame 9 are fixedly connected through the locking pin 13, and then the motor 4 is started. The motor 4 drives the rotating shaft 8 to rotate through the reducer 5. The rotating shaft 8 drives the rotating frame 9 to rotate, so that the rotating frame 9 drives the rotating sleeve 7 to rotate through the locking pin 13 and the protruding rod 12, and then the rotating sleeve 7 drives the wheel 6 to rotate, so that the rolled water hose can be transferred to the water hose truck. After the rolled water hose is transferred to the destination, the pressure plate 11 is removed from the rotating frame 9 by removing the screws, so that the rotating rod 10 can be removed from the groove on the rotating frame 9, and then the rolled water hose can be taken out and the rotating rod 10 can be pulled out. The water hose can be rolled up and carried, which greatly reduces labor intensity, improves work efficiency, and helps to quickly carry out emergency rescue.

[0029] When releasing the water hose, the water hose is installed on the rotating rod 10, and the rotating rod 10 is fixed on the rotating frame 9 through the pressure plate 11, and then the protruding rod 12 and the corresponding rotating frame 9 are fixedly connected through the locking pin 13, and the motor 4 is started. The motor 4 drives the rotating shaft 8 to rotate through the reducer 5, so that the rotating shaft 8 drives the rotating frame 9 to rotate, so that the rotating frame 9 drives the rotating sleeve 7 to rotate through the locking pin 13 and the protruding rod 12, and then the rotating sleeve 7 drives the wheel 6 to rotate, so that the water hose is transported to the place where the water hose needs to be released, and then one end of the water hose is sent away from the rotating rod 10, so that the rotating frame 9 drives the wheel 6 to move while releasing the water hose, which greatly reduces labor intensity, improves work efficiency, and helps to quickly carry out emergency rescue.

[0030] The operator only needs to hold the handrail 3, operate the switch with the thumb, and pay attention to adjusting the forward direction, so that the two heavy physical labors of winding and carrying can be realized, the labor intensity can be reduced by more than 80%, and the efficiency can be improved by 2-3 times.
