Field of the Invention The present invention relates to a jellyfish removing device installed at an intake for taking in seawater as cooling water at, for example, a power plant or a factory, and particularly for taking water at an open end on the ocean side of the intake. The present invention relates to a jellyfish removing device for a seawater intake, in which a cover having an opening is attached and a water flow along the cover is generated to prevent the jellyfish from entering the intake.

てクラゲの侵入を防止する。2. Description of the Related Art Jellyfish have a specific gravity almost equal to that of the surrounding seawater, float in the sea, and basically move on the ocean current. Therefore, when seawater is taken as cooling water at a power plant or factory, there is a possibility that jellyfish floating around the intake will be naturally taken into the intake. As a countermeasure against this, the following jellyfish elimination device has been conventionally proposed. (1) As shown in FIG. 12, when seawater is taken in using the intake pipe 11, the nets 2 and 3 are intake openings 11 of the intake pipe 11.
Stretch around a to prevent jellyfish from entering. (2) As shown in Fig. 13, if the intake is large, intake 1
A belt conveyor 4 is provided inside and a grating 5 attached to the conveyor 4 catches jellyfish from seawater to prevent intrusion of jellyfish.

大な設備費用が必要となるなどの問題点がある。Further, in the case of the jellyfish eliminating device in which the belt conveyor with grating is arranged in the water intake shown in FIG. 13, since the jellyfish are suspended in seawater, the speed of the belt conveyor cannot be increased so much. In addition, there is a problem that jellyfish may invade between the lower end of the belt conveyor and the bottom of the water intake, and the equipment itself becomes bulky, which requires a large amount of equipment cost.

い。In the above-mentioned structure, when water is taken from the water intake 1 while driving the propeller 7 to generate the water flow 10 in the water passage 21, the water flow 10 collides with the surface of the cover 6 and the water flows on the surface of the cover 6. It is possible to eliminate the jellyfish 8 that has adhered or is about to adhere. At this time, since the slit-shaped opening 9c is open to the lower end side of the water flow, there is no possibility that the jellyfish moving with the water flow will flow in from the opening 9c. Further, since the flow velocity V 1 of the water flow 10 is set to be higher than the flow velocity V 3 of the slit-shaped opening 9c of the guide plate 9a, there is no possibility that jellyfish floating in the water flow will be sucked into the intake opening. Further, the clearance between the slit-shaped opening 9c of the guide plate 9a attached to the outside of the cover 6 of the water intake 1 and the side wall surface of the cover 6 is set to be narrower than the size of the jellyfish 8. There is no risk of the jellyfish 8 entering.

れる。As described above, there is no possibility that the jellyfish 8 approaches the cover 6, and therefore, even if the gap between the guide plate 9b and the side wall surface of the cover is set to be narrow, there is no possibility that the jellyfish will be clogged in this gap. .. Further, a swirling flow as indicated by an arrow C is also generated at a position away from the cover 6. Due to this swirling flow, like the jellyfish denoted by reference numeral 11, the action of being swept away to the ocean side is also achieved without approaching the water intake 1.

受ける開口面積を多くとることができる。As described above, in the jellyfish eliminating device at the seawater intake of this embodiment, a wedge-shaped cover is attached to the intake and a rudder plate is attached to the outside of the cover to form a water channel between both members, A water flow from a propeller is generated in this waterway to drive the jellyfish out of the water inlet, while a guide plate is placed outside the many water intake openings provided in the cover, and a gap is provided between the guide plate and the wall surface of the cover. To provide a seawater intake device that has a relatively simple structure and that can reliably prevent intrusion of jellyfish at the time of water intake from the water intake opening formed in the cover by installing it with a diameter smaller than that of the jellyfish. You can Further, in the case of this embodiment, since the water intake opening is formed on the oblique side wall surface of the wedge-shaped cover 6, a large number of water intake openings can be formed, and a large opening area for receiving the water flow can be obtained.

Further, the increase in the size of the water intake port can be dealt with by increasing the size of the cover 6 and increasing the number of propellers 7. Next, in the modified example of the water intake opening shown in FIGS. 7 to 9, while the water intake opening 9b ′ formed on the side wall surface of the cover 6 is formed in a communication manner in the longitudinal direction of the cover 6, The scale-like opening 9 shown in FIGS. 1 to 6 is different in that one guide plate 9a 'is attached to the outside of the water intake opening 9b' to form an opening 9 '. .
In addition, the gap of the slit-shaped opening 9c 'formed between the tip of the guide plate 9a' and the side wall surface of the cover 6 is set to be smaller than the jellyfish diameter, and the size of the opening 9b ', etc. Needless to say, is set under the same conditions as the above [Formula 1] and [Formula 2]. Also works
There is no difference in terms of effectiveness. In the second embodiment shown in FIGS. 10 and 11, a flat cover 16 is attached to the open end of the intake 1 on the ocean side.

The propeller 7 is driven via a shaft 14 by a land-mounted engine 13 installed on an upper part of a cover 16 to generate a water flow 10 in a water channel 22. Meanwhile, the cover 16
A large number of water intake openings are formed, and a guide plate inclined toward the downstream side of the water flow 10 is attached to each water intake opening.
A scaly opening 9 similar to that in the embodiment is formed.
It goes without saying that the size and the like of the scaly opening 9 are set under the same conditions as those of the scaly opening 9 in the first embodiment, and the jellyfish elimination at the seawater intake of the second embodiment is performed. Also in the device, a jellyfish eliminating action similar to that of the first embodiment is exhibited.
