Description

Fixed jellyfish capture device {STATIONARY TYPE JELLYFISH CAPTURING APPARATUS}

The present invention relates to a fixed jellyfish capture device, and more particularly to a fixed jellyfish capture device that can effectively capture jellyfish swimming in accordance with algae.

In recent years, due to environmental pollution, jellyfish inhabiting the oceans are approaching the sea, and the catches of nearby fishes are decreasing.In case of fishing using the nets, the fishermen A separate labor force is required to remove the jellyfish, and the damage caused by the jellyfish has been severely shown, such as when the net is broken.

Jellyfish can be classified into about 200 species. Among them, only 4 species of edible jellyfish are available, so most of them are land jellyfish that cannot be eaten. Efforts have been made to remove the jellyfish by installing a funnel-shaped net to widen the entrance to allow the jellyfish to naturally enter the net, but recently, the net has been torn due to the large increase in the amount of jellyfish. It is difficult to be damaged and used.

In addition, even if the jellyfish are caught in the net, the size of the net is tens or hundreds of meters, so it takes a lot of labor and money to remove the jellyfish trapped in the net. It not only acts as a barrier to fishing, but also requires its cost or astronomical amount, so it is ineffective.

The maintenance process, the fixation process, the bird flow direction confirmation process and the migration process are performed sequentially or independently or in combination.

In the case where the fixed jellyfish trapping device is initially installed, the control unit 9 of each of the first and second floating devices 10L and 10R may be configured based on the distance detection value from the respective distance detection unit 8. The opening width between the second floating devices 10L and 10R is calculated, and the predetermined opening width is compared with the calculated opening width. If the predetermined opening width and the calculated opening width are different, each of the control units 9 controls the respective moving units 5 to move the first and second floating devices 10L and 10R, respectively, to the first and the first openings. The holding process is performed such that the opening width between the two floating devices 10L and 10R is equal to the predetermined opening width or within a predetermined range of errors.
