Abstract: PURPOSE: To provide a simple and an inexpensive title device for automatically draining selectively salt water at a bottom part without using any electric power, by opening a drainpipe as a result of a hollow floating object being buoyed up in the case of the difference in a water level between at the upstream and the downstream of a tide gate being larger than a critical water level, and by closing the drainpipe as a result of the floating object falling down in the case of the difference in the water level being smaller than the critical water level.  
     CONSTITUTION: An apparant weight of a facing weight 16 is adjusted so that a buoyancy F produced in the case of a water level at the upstream being controlled will coincide with an apparant weight W of a hollow floating object 9. In the case of a difference ΔH in a water level between at the upstream and at the downstream being smaller than a sea water backward flow check critical water level ΔHc, it is represented by F=1×ΔH×A, where A is a horizontal cross-section of the hollow floating object 9. In the case of ΔH<ΔHc, a relation of F and W becomes an inequality of F<W, and as a result the floating object 9 falls down to close an end part 8 of a drainpipe 7, which results in preventing a sea water backward flow. In the case of ΔH>ΔHc, it becomes the inequality of F>W, and as a result the floating object 9 is buoyed up to open the end part 8 of the drainpipe, and thus, salt water at a bottom part H 2  is drained selectively and fresh water at a upper part H 1  is not drained.
