s6, when the siphon drainage pipe is cut off under an extreme condition, water is deficient in the water storage tank (6), gravity is reduced, the linear elastomer material (7) rises, the elevation of the water storage tank (6) rises to the position of the water replenishing cover bin, the distance monitoring of the laser sensor changes at the moment, the electromagnet (12) is controlled by the controller to generate adsorption force to hold the water storage tank (6) tightly, the water replenishing pump is controlled to perform continuous water replenishing action for N seconds, water is reversely filled into the siphon drainage pipe (4) after being filled into the water storage tank, the reverse water filling of the siphon drainage pipe (4) is stopped after gas in the siphon drainage pipe (4) is discharged, siphon drainage is started, the electromagnet, the laser sensor and the water replenishing pump are reset at the moment, and then S2-S5 is repeated.
