[0046] after the controller controls the pump set device 2 to start, the water in the water tank 1 is then delivered into the pipeline under the action of the water pump, the water in the water tank 1 moves from one side of the water inlet 11 to the water outlet 12, and during the delivery of the water in the water tank 1, the water flow impacts the impeller blade 34, the impeller blade 34 then generates a rotating force under the action of the water flow, and the impeller blade 34 then rotates; and during the rotation of the impeller blade 34, the impeller blade 34 drives the support arm 33 to rotate, the rotation of the support arm 33 drives the rotation of the retaining ring 32, and when the retaining ring 32 rotates, the retaining ring 32 drives the rotating shaft 31 to rotate;

[0049] the rotation drives the rotating gear 352 in the power cavity 351 to rotate; since the rotating gear 352 is an incomplete gear, when the sliding block 38 moves to the end of the sliding groove 37, the rotating gear 352 is disengaged from the constraint of the teeth at this moment, and then the rotating gear 352 is reset under the action of the torsion spring; and in the process of resetting, the rotating gear 352 drives the rotating shaft to reset, the rotating shaft drives the cleaning rod 36 to reset, and the cleaning rod 36 rotates to one side of the cleaning groove 35, so as to realize multiple intermittent cleaning of the inner wall of the water tank 1;

[0050] when it is necessary to stop the water supply, when the controller is controlling the pump set device 2 to turn off, the controller controls the electromagnetic spring in the moving groove 39 to be energized, and the electromagnetic spring contracts upon being energized; in the process of the contraction, the electromagnetic spring drives the retaining ring 32 to move, the retaining rings 32 on two sides move along the moving groove 39 to one side away from the water inlet 11 and one side away from the water outlet 12 respectively, and then the controller controls the pump set device 2 to turn off; at this moment, the staggered impeller blades 34 are combined into one impeller whole, water forms a water hammer after the valve is closed, the water hammer impacts on the impeller blades 34, and the staggered impeller blades 34 disperse the impact force of the water hammer; and therefore, the influence of the water hammer on the pump set device 2 is reduced, and the pump set device 2 is protected; and

[0062] when it is necessary to stop the water supply, when the controller is controlling the pump set device 2 to turn off, the controller controls the electromagnetic spring in the moving groove 39 to be energized, and the electromagnetic spring contracts upon being energized; in the process of the contraction, the electromagnetic spring drives the retaining ring 32 to move, the retaining rings 32 on two sides move along the moving groove 39 to one side away from the water inlet 11 and one side away from the water outlet 12 respectively, and then the controller controls the pump set device 2 to turn off; at this moment, the staggered impeller blades 34 are combined into one impeller whole, water forms a water hammer after the valve is closed, the water hammer impacts on the impeller blades 34, and the staggered impeller blades 34 disperse the impact force of the water hammer; and therefore, the influence of the water hammer on the pump set device 2 is reduced, and the pump set device 2 is protected;

[0063] the cleaned impurities are delivered to the water outlet 12 under the action of the water flow; and during the delivery, the impurities encounter a filter screen provided in the water outlet 12, and the impurities are then filtered by a filter plate screen;
