〔産業上の利用分野〕
本発明は養殖用又は定置用魚網等の海水浸漬網状構造物
に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to seawater-immersed net structures, such as fish nets for aquaculture or stationary use.
（従来の技術〕
例えば、魚介類の養殖に使用されるいけす用魚網の防汚
手段として有機錫系の毒物を魚網に含浸させ、それを溶
出させることにより防汚するものが一般的に使用されて
いる。(Prior art) For example, as a means of preventing fouling of fish nets for fish cages used in the cultivation of fish and shellfish, a method is generally used that impregnates the fish net with an organic tin-based poison and causes it to leach out. ing.
しかしながら、この種の魚網による構造のいけすには下
記のような問題がある。However, this type of fish net structure has the following problems.
＋１） 最近有機錫系の防汚塗料の使用が困難となっ
ている関係上、それに代わる環境汚染がなく、魚介類に
対し毒性の少ない防汚手段が必要である。+1) Since it has recently become difficult to use organic tin-based antifouling paints, there is a need for an alternative antifouling means that does not pollute the environment and is less toxic to seafood.
（２）防汚成分溶出速度を調節することができないので
、季節、海域、水質変化等に自在に対応することができ
ない。(2) Since the elution rate of antifouling components cannot be adjusted, it is not possible to freely respond to changes in season, sea area, water quality, etc.
（３）魚網に含浸できる毒物含有量には限度があり、半
年〜２年ごとに毒物を含浸させる作業が必要である。(3) There is a limit to the amount of toxic substances that can be impregnated into fishing nets, and it is necessary to impregnate them every six months to two years.
本発明はこのような事情に鑑みて提案されたもので、有
機錫等の有毒性材料を使用せずに海洋生物の付着を防止
する安全かつ経済的な海水浸漬網状構造物を提供するこ
とを目的とする。The present invention was proposed in view of the above circumstances, and aims to provide a safe and economical seawater-immersed net structure that prevents the adhesion of marine organisms without using toxic materials such as organic tin. purpose.
そのために本発明は、銅又は銅合金を材料とした海水中
の網状構造物において、上記網状構造物を陰極と、上記
網状構造物の外方の海水中に適宜距離を存して対置され
た非溶性陽極と、上記非溶性陽極から上記網状構造物へ
直流電流を通電する手段とを具えたことを特徴とする。To this end, the present invention provides a network structure in seawater made of copper or a copper alloy, in which the network structure is placed opposite to a cathode at an appropriate distance in the seawater outside the network structure. It is characterized by comprising an insoluble anode and means for passing a direct current from the insoluble anode to the network structure.
このような構成によれば、金網材料として用いている銅
又は銅合金から海水中に銅イオンが溶出し、その毒性に
より海洋生物付着を防止する。According to such a configuration, copper ions are eluted into seawater from the copper or copper alloy used as the wire mesh material, and the toxicity thereof prevents the attachment of marine organisms.
金網の表面に酸化物の不活性成分が生成し、銅イオンの
溶出速度が低下したときは、金網を陰極として海中に電
流を流すことにより表面酸化物を還元活性化し、銅イオ
ンの溶出量を初期の状態に戻すことができる。When an inert component of oxide is generated on the surface of the wire mesh and the elution rate of copper ions is reduced, the surface oxide is reduced and activated by using the wire mesh as a cathode and passing an electric current into the sea, reducing the amount of copper ions eluted. It can be returned to its initial state.
本発明をいけすに通用した一実施例を図面について説明
すると、第１図はその斜視図である。An embodiment in which the present invention is applied to a cage will be described with reference to the drawings. FIG. 1 is a perspective view thereof.
上図において、１は海水中に：＆漬されたいけすを形成
する魚網、２は魚網１を構成する銅又は銅合金で製作さ
れた金属製立体網、３は交流電源を整流して直流とする
直流電源、４はＰｔ、カーボン等よりなる棒状陽極であ
る。In the above diagram, 1 is a fishing net that forms a cage submerged in seawater, 2 is a three-dimensional metal net made of copper or copper alloy that constitutes fishing net 1, and 3 is a rectified AC power source that converts it into DC. 4 is a rod-shaped anode made of Pt, carbon, or the like.
このような構造によれば、金属製立体網を形成する銅線
から発生する銅イオンにより海洋生物は立体網に付着し
にくくなる。According to such a structure, marine organisms are less likely to adhere to the three-dimensional metal network due to copper ions generated from the copper wires forming the three-dimensional metal network.
また、金網表面が酸化物で覆われて銅イオンの発生が少
なくなったときは魚網１と魚網１の外方に対向して設置
された棒状陽極４との間に直流電源３から金属製立体網
２を陰極として直流電流を流す。In addition, when the surface of the wire mesh is covered with oxides and the generation of copper ions is reduced, a metal three-dimensional A direct current is passed through the net 2 as a cathode.
そうすると、陰極である金属製立体網２には水素が発生
し、魚網表面のＣｕ２０゜ＣｕＯなどの不活性分を還元
し、Ｃｕが形成され、銅イオンが溶出し、防汚性能が初
期の状態に戻るので、防汚有効期間が大幅に延びる。Then, hydrogen is generated in the metal three-dimensional net 2, which is the cathode, and inert components such as Cu20°CuO on the surface of the fishing net are reduced, Cu is formed, copper ions are eluted, and the antifouling performance returns to its initial state. , the effective period of antifouling is significantly extended.
このような銅又は銅合金で製作した魚網では、従来、３

~ After 6 months, a barnacle appears.
むらさきいがい、セルプラなどが付着したが、本発明の
陰極活性化法を併用することにより２年経過しても海洋
生物の付着は見られなかった。Although purple snails, cellupla, etc. were attached, no marine organisms were observed to attach even after 2 years by using the cathode activation method of the present invention.
