があった。(Problems to be Solved by the Invention) The conventional jellyfish eliminating device for the water intake shown in FIGS. 5, 6, and 7 has the following problems. That is, the intake (0
In 1), the frontage is as long as 80 m. The jellyfish inflow prevention net (05) is stretched over the entire area of the intake port (01), and the jellyfish elimination ship (06) is anchored on the sea surface outside the jellyfish inflow prevention net (05). When the jellyfish elimination water streams (03a) (03b) are generated in opposite directions to eliminate the jellyfish (011), the jellyfish elimination water streams (03a) (03b) immediately after the propellers (09a) (09b)
Is strong, but then weakens rapidly, so the intake (01)
Jellyfish (011) cannot be sufficiently eliminated because a strong jellyfish elimination water flow (03a) (03b) cannot be formed over the entire frontage. If the jellyfish (011) is to be eliminated sufficiently, the jellyfish elimination vessel (06) with large horsepower must be used to form a strong jellyfish elimination water flow (03a) (03b). In addition, as shown in Fig. 7, when the jellyfish elimination water flow (03a) goes backwards to the tidal current (02), the jellyfish (011) once eliminated in the direction away from the jellyfish inflow prevention net (05) flows into the tidal current (02). ) Get on the water intake again (01)
There was a problem in that the jellyfish (011) could not be eliminated sufficiently because it sometimes went around in the direction of () (see (03c)).

ラゲ排除装置を提供する点にある。The present invention is proposed in view of the above-mentioned problems, and its purpose is to wrap around the sea surface outside the jellyfish inflow prevention net in the net direction without using a large horsepower jellyfish elimination ship. Even if there is a tidal current, it is possible to reliably remove jellyfish offshore, and to provide a jellyfish elimination device for the intake that can also effectively eliminate jellyfish clogging the mesh of the jellyfish inflow prevention net.
