<p>The present invention provides an underwater spraying device for preventing red tide, which comprises: a floating body coupled with a storing tank having a preventing material stored therein; a discharge line having one end connected with a storing tank and the other end extending to be disposed in a lower part under a water surface, wherein a plurality of discharge holes are disposed at regular intervals in a length direction in the other end part disposed in a lower part of the water surface to discharge the preventing material; a pressure pump connected with one side of the discharge line while being provided on the floating body, and pumping the preventing material of the storing tank to be transferred to the other end of the discharge line; a plurality of control valves formed to be spaced apart from each other in a length direction of the discharge line, and controlling discharge of the preventing material through each discharge hole; and a ballast connected with the other end in a length direction of the discharge line, and horizontally maintaining the other end part of the discharge line disposed in a lower part of the water surface. In the underwater spraying device for preventing red tide, while one end of a discharge line is connected with a storing tank of a floating body, the other end thereof is dipped in a lower part of a water surface, and a preventing material in the storing tank may be discharged through discharge holes formed to be spaced apart from each other in a length direction of the dipped other end part of the discharge line, so the preventing material is discharged by each water depth in a lower part of the water surface. Accordingly, a preventing effect is improved. At the same time, a discharge state and a discharge amount through discharging holes for each water depth in a lower part of the water surface are controlled by a control valve, so preventing work according to red tide concentration in a lower part of the water surface can be effectively performed.</p> |
