The body is slidingly inserted into the outer surface of an inflow pipe and moves up and down according to the change in water level. The buoyancy adjusting member is fixed on the outer surface of the body, and adjusts buoyancy by adjusting the ratio of the water and air. The device for preventing inflow of a material is fixed on the upper surface of the body. |
