[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for preventing attachment of aquatic organisms, etc., near a waterfall in a structure provided in the sea or lake.

[0002]

2. Description of the Related Art Oysters, barnacles or seaweed organisms are found near structures near the surface of water such as structures installed in the sea or lakes, such as lantern buoys, wave power buoys, and pillars standing on the bottom of the water. Etc. are easy to attach. Therefore, antifouling paints have been developed and painted.

[0003]

[Problems to be solved by the invention] Still, it is difficult to prevent attachment, and light buoys, wave power buoys, etc. are regularly pulled up to the ground, scraped off attachments, cleaned, repainted and set targets etc. It required a lot of maintenance work.

[0004] In particular, there are many biological attachments in the vicinity of the stall, which adversely affects the performance of the buoy. The present invention is an antifouling device designed to prevent attachment of aquatic organisms, etc. near a ditch with a simple device.

[0005]

[SUMMARY OF] To achieve this object, the present invention, Oite the structure having a columnar portion that penetrates the water surface vertical, outer periphery or inner periphery of the contact surface of the water as appropriate gap columnar portion
A ring-shaped floating body with water on the outside or inside of the column
The ring-shaped floating body is fitted or inserted to the columnar portion so as to float.
2 is the contact between the buoyant body ring made of a lightweight material and the columnar part.
The water surface goes up and down because it consists of wear resistant parts on the touch side.
More antifouling by rubbing the water contact surface of the columnar part
It is an antifouling device.

Further, the ring-shaped floating body and one or a plurality of wear resistant rings connected to the floating body with an appropriate gap.
It is an antifouling device consisting of .

[0007]

[Function] The water surface moves up and down due to waves and tides, and the ring-shaped floating body that moves up and down accordingly rubs the outer or inner surface of the columnar part of the floating structure, which prevents oysters or algae and other aquatic organisms from adhering to the surface, resulting in contamination. Can be prevented. This range can prevent soil pollution in the floating buoy in the floating structure example, and in the case of the structure example where the tidal range influences the tidal range, in the case of the pillar mark or the retractable mooring spar buoy standing on the water bottom.

By connecting the rings to the ring-shaped floating body in multiple stages, the antifouling range can be further expanded by the distance between the rings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a conceptual view showing an example in which the present invention is applied to a retractable mooring type spar buoy 1, 2 is a ring-shaped floating body of an antifouling device, 3 is a column body, 4 is a buoyancy body, and 5 is a sinker. Then, the buoyancy body 4 is pulled into the water by the short mooring tool 6 and moored, and the pillar body 3 stands upright in the water due to the buoyancy. The water line is located in the middle of the standard body above the buoyancy body, and the outer circumference of the standard body in the range of tidal difference + wave height is rubbed by the ring-shaped floating body 2 to prevent soiling.

FIG. 2 is a conceptual diagram showing an example in which the present invention is applied to the outer periphery of the columnar portion of the buoyant body 4 of the floating lamp buoy 7. Since the buoyant body floats on the water surface, the range of wave height is ringed. Antifouling with the floating body 2.

FIG. 3 is a partially cutaway conceptual view showing an example in which the present invention is applied to the inner surface of the piston chamber 9 of the wave power generation buoy 8. The range in which the liquid level rises and falls due to the waves on the inner circumference of the piston chamber 9 is ringed. The floating body 2 rubs against soil.

FIG. 4 is a partially detailed side view of the ring-shaped floating body 2 of the antifouling device provided on the outer periphery of the columnar portion of the embodiment shown in FIGS. 1 and 2. The ring-shaped floating body 2 is arranged on the contact side between the buoyant body ring 10 made of an ultra-light material such as urethane foam and the columnar portion.
It is formed of a wear resistant portion 11 such as urethane rubber, and is formed in a ring shape so as to float on the water surface. The outer surface of the columnar portion and the contact portion of the ring floating body have an appropriate gap, the ring floating body moves up and down due to the waves, and the top side surface is appropriately rubbed for cleaning.
Antifouling.

FIG. 5 is a detailed side view of a part of the ring-shaped floating body 2 of the antifouling device floating on the water surface in the piston chamber 9 of the wave power generation buoy shown in FIG. The structure of the ring-shaped floating body 2 is the same as that of the outer peripheral type.

FIG. 6 is a detailed sectional side view of an antifouling device in which rings are further provided on the ring-shaped floating body 2 in multiple stages. In this embodiment, the antifouling device is provided on the outer periphery of the column body. Floats on the water surface, and wear-resistant rings 12 made of a wear-resistant material are held in parallel by a plurality of holding bars 13 at appropriate intervals below the water surface. This is a multi-stage ring type antifouling device in which the antifouling range is expanded further down by the ring interval. If it is desired to further expand the antifouling range, a ring may be additionally installed below or above.

FIG. 7 shows an embodiment in which a multistage ring-shaped antifouling device is provided on the inner circumference of a sensor hole which vertically penetrates the floating body 4 of the ocean observation buoy. The ring-shaped floating body 2 floating on the water surface
The ring 12 located in the water therebelow is held at a predetermined interval by a plurality of interval holding bars 13. 14 is a sensor.

FIG. 8 shows an embodiment in which a multistage ring-shaped antifouling device is provided on the inner circumference of a feeding pipe which vertically penetrates the floating body 4 of the feeding buoy. The ring-shaped floating body 2 floating on the water surface holds a ring 12 ′ located above the ring-shaped floating body 2 at a predetermined interval by a plurality of interval holding bars 13. In this embodiment, each of the ring cross sections is formed with an acute angle at both the upper edge and the lower edge so that the bait for feeding does not pile up on the ring and the bait attached to the inner surface is easily scraped off. This eliminates the drawback that the pipe is apt to be clogged by the bait attached to the upper part of the water supply inside the feeding pipe.

[0018]

With the antifouling device according to the first aspect of the present invention, in the floating structure, the ring-shaped floating body moves up and down due to the waves in the range of the wave height, and the side surface of the columnar portion is rubbed to clean and prevent the dirt.
In addition, in the case of a standard pole standing on the bottom of the water or a retractable mooring type spar buoy, the water line moves up and down depending on the tidal level, so the range of tidal range + wave height can be prevented. In particular, if the inner circumference of the pillar is soiled by this device, it will be too narrow to clean the inner circumference of the piston chamber of the wave power generation buoy described in the above embodiment, the inner circumference of the sensor hole, and the inner circumference of the feeding pipe. This makes it extremely easy to prevent stains on the inner circumference of the pipe.

If the antifouling device according to the second aspect is used, there is an effect that the antifouling range can be further expanded by the distance between the rings.
