ていない現状である。(Conventional technology) Phytoplankton such as blue-green algae in lakes and red tide in the sea have been occurring in the past, causing various problems such as abnormal proliferation and wrapping around the screws of fishing boats, mass death of fish, and the production of bad odors. I'm letting you do it. There are also methods that use oil fences to capture blue-green algae or red tide and prevent their spread, or methods that collect floating plankton using a vessel equipped with a vacuum and incinerate and dispose of it through processes such as dehydration, drying, and incineration. Although it does exist, it has the drawback of requiring expensive equipment and workers, resulting in large costs, and the current situation is that it has not been able to sufficiently improve the environment of lakes, seas, rivers, etc.

It has a long floating body 2 on its upper part and a weight 3 on its lower part.The outer periphery of the floating body 2 is covered with a resin net 5, and both ends are covered with a vinyl chloride sheet 6. A coconut shell fiber network 1 formed by weaving twisted threads into a tight mesh is fixed with clips 9 at appropriate intervals. Reference numeral 7 is a wire for connecting the floating bodies 2, and 8 is a connecting tool, by which long floating bodies 2 are successively connected to form a fence-like net of a desired size.

のを防止しなければならないものである。(Problems to be solved by the invention) However, there is a risk that the coconut shell fiber network 1 of the conventional fence section may be washed downstream by traction, tidal currents, river currents, etc., and some phytoplankton may pass through from the bottom. Therefore, the weight of the weight 3 must be increased, and the coconut shell fiber network 1 must be formed sufficiently long in the vertical direction, which is extremely uneconomical. It is necessary to effectively prevent water pollution in rivers, lakes, etc. that have the risk of damaging the fiber network 1 and are used as water resources such as drinking water and recreational water. Therefore, it is necessary to prevent even some of the phytoplankton from dispersing.

A band-shaped elastic body 18 is attached along the vertical direction. The elastic body 18 is made of a plate spring, an elastic wire, or the like, and is curved in advance. The upper end of the elastic body 18 is fixed to a side L-shaped fixing member 19 fixed to the floating body 12,
A plurality of coconut shell fiber network bodies 16 are provided at appropriate intervals in the longitudinal direction of the floating body 12, for example, at intervals of 3 to 5 m, so that the coconut shell fiber network bodies 16 are curved along the curve of the elastic body 18. It is also possible to adjust the attachment state by adjusting the angle of the L-shaped bent portion of the fixing member 19 and attaching the elastic body 18 at a different angle.

面積が減少するものである。 Therefore, when there is a current in the direction indicated by the arrow a in FIG. 2, the skirt portion 16b of the coconut shell fiber network 16 will be in a vertically downward position as shown by the imaginary line rather than in the curved state shown by the solid line. The effective area for capturing sexual plankton corresponds to the size of the skirt portion 16b, increasing efficiency. Incidentally, when the skirt part 1 is uncurved and receives a current in the direction of arrow a, the skirt part 1 shown by the imaginary line
6b', the effective trapping area of the skirt portion 16b' is reduced.

It is necessary to set the floating body 12 so that it protrudes about 25 to 30 cm above the water surface to prevent phytoplankton from climbing over the floating body 12. Furthermore, if the lower end of the skirt portion 16b hangs downward due to the weight of the elastic body 18, the weight 20 can be omitted.
