The invention relates to the technical field of fire-fighting reels, and discloses an automatic winding fire-fighting reel which comprises a base support and a center pipe. A reel pipe is wound on the reel; the control mechanism is used for controlling winding of the reel pipe and drainage during winding; one end of the central pipe is connected with a valve pipe, and a connector is arranged on the valve pipe. According to the automatic winding fire-fighting reel, automatic electric winding of the reel can be achieved through the arranged servo motor, meanwhile, the servo motor is disconnected with the reel, the overall water pipe pulling-out resistance is reduced, the water pipe is pulled out more smoothly, and therefore the winding efficiency of the water pipe is improved. A circulating inflating structure is formed by utilizing the rotating power of the water pipe in the winding process, the wound water pipe is continuously inflated, then accumulated water in the water pipe is subjected to air pressure type inflating and self-discharging, it is guaranteed that the accumulated water in the water pipe can be effectively discharged, therefore, the protection performance of the water pipe is improved, and the material hardening condition caused by long-time water accumulation is avoided.
