<p><P>PROBLEM TO BE SOLVED: To provide a non-powered underwater aerator capable of being utilized without boring a hole in the bank body of a reservoir such as a dam lake. <P>SOLUTION: This underwater aerator 1 is equipped with a water sucking pipe 11 provided in the dam lake 3 and an air intake pipe 12. An air-water separation tank 13 is provided under the water sucking pipe 11 and an air diffusion pipe 14 is provided in the air-water separation tank 13. A water discharge pipe 20 is connected to the air-water separation tank 13 and the water sent out of the air-water separation tank 13 is discharged through the water discharge pipe 20. The water discharge pipe 20 is provided so as to straddle the bank body 2 and provided with priming piping 21. When priming is taken out of the priming piping 21, water can be taken out of the air-water separation tank 13 by a theory of a siphon without using power, and therefore, the dam lake 3 can be aerated. <P>COPYRIGHT: (C)2004,JPO</p> |
