<p>PROBLEM TO BE SOLVED: To provide a water suction device capable of favorably preventing generation of cavitation or lack of liquid without causing expensive cost. SOLUTION: A suction port 15 is formed at one end 13a of a suction pipe 13 which can be bent, a pump 16 is disposed at the other end 13b, the suction port 15 is disposed at a deep part in a water zone W, the suction tube 13 is disposed so that the highest part 21 positioned at a higher place than the other parts is formed in at least a part between one end 13a and the other end 13b, the highest part 21 is formed at a lower position than a static water surface Ws of the water zone W, and it is provided at such a position that a height difference H between the highest part 21 and the static water surface Ws is larger than a limit burying depth C.</p> |
