The use method and the working principle of the embodiment are as follows:
under normal conditions:
under the action of the pulling force of the tension spring 9, a certain distance can be kept between the sealing baffle 11 on the flashboard 10 and the tail end of the sewage discharge pipeline 1, so that the tail end of the sewage discharge pipeline 1 is in a normally open state, sewage in the sewage discharge pipeline can be smoothly discharged and the flashboard 10 is not required to be squeezed open under certain pressure, so that the sewage in the sewage discharge pipeline 1 can be completely discharged, deposition and scaling of solid pollutants cannot be formed due to long-time retention in the sewage discharge pipeline 1, and meanwhile, deterioration due to long-time retention of the sewage in the sewage discharge pipeline 1, pungent odor is generated, bacteria and other viruses are bred;
when the tail end of the sewage discharge pipeline 1 is submerged by river and lake water:
under the action of the buoyancy of water, the buoyancy ball 5 can be driven to rotate gradually along the movable clamping ring 3 as a rotating center, and the connecting rod 7 is driven to move inwards along the track of the transmission chute 8 and stretch the tension spring 9 under the action of the rolling sliding group 6 on the movable clamping ring 3, so that the sealing baffle plate 11 on the gate plate 10 gradually approaches to the tail end of the sewage discharge pipeline 1 until the sealing baffle plate is completely attached to the tail end of the sewage discharge pipeline 1, and the sealing operation on the tail end of the sewage discharge pipeline 1 is further realized;
when the river and lake water at the tail end of the sewage discharge pipeline 1 is removed:
the buoyancy ball 5 finally tends to the balanced state because of losing the buoyancy of water and gradual anticlockwise rotation under the effect of balance ball 4, drives connecting rod 7 to move to the outside under the transmission of roll gliding group 6 and transmission spout 8 and the pulling force effect of tension spring 9 simultaneously for separation gradually between the tail end of the last sealing baffle 11 of flashboard 10 and sewage pipes 1 is until it separates to maximum position department, causes the tail end of sewage pipes 1 to be in normally open state.
