The invention relates to the technical field of dust and snow sweeping, and discloses a reel mechanism, a rope deploying and retracting mechanism provided with the reel mechanism, and a sweeping device provided with the rope deploying and retracting mechanism. The reel mechanism comprises a reel and a unidirectional wheel mechanism connected with the reel, and the unidirectional wheel mechanism is connected with a power shaft. When the power shaft rotates towards one direction, the unidirectional wheel mechanism drives the reel to rotate. When the power shaft rotates towards another direction, the unidirectional wheel mechanism is in a free state. By arranging two reel mechanisms which are opposite in direction, the technical problem that the reel mechanisms do not rotate synchronously can be solved, the operation stability of a dolly can be improved, the service life of the sweeping device is prolonged, and the power set can be prevented from being burnt out.
