Description
【考案の詳細な説明】 〔産業上の利用分野〕 この考案は、汚濁防止膜に関するものである。[Detailed explanation of the idea] [Industrial application field] This invention relates to an anti-fouling membrane.
従来の汚濁防止膜は、フロートと、このフロー
トに上縁を支持させて垂れ下げた横方向に長いシ
ートとで構成されている。
A conventional anti-fouling membrane is composed of a float and a laterally long sheet that hangs down with its upper edge supported by the float.
なお、上記のシートには、透水性のあるものが
用いられる。 Note that the above-mentioned sheet is water permeable.
シートには、貝が付着し、且つ付着量が増加す
るにともないシートの重量がふえる。
Shellfish adhere to the sheet, and as the amount of adhesion increases, the weight of the sheet increases.
シートの重量が増加すると、フロートを引き下
げて水面下に没入させて汚濁防止機能を失うの
で、定期的な貝の除去作業が必要になる。 As the weight of the sheet increases, the float is pulled down and submerged below the surface of the water, losing its anti-fouling function and requiring periodic removal of shellfish.
上記具の除去作業は、海水内や作業船上に引き
上げて人手により掻き落すので、著しく手数がか
かると共に、作業船上で除去作業する場合、その
間汚濁防止機能を失う問題があつた。 Removal of the above-mentioned tools involves lifting them into seawater or on a work boat and scraping them off manually, which is extremely time-consuming, and when the removal work is carried out on a work boat, there is a problem in that the pollution prevention function is lost during the removal work.
また、貝の掻き落しにともないシートを破損す
ることがあり、破損したシートの交換に手間がか
かる問題もあつた。 In addition, there was a problem in that the sheet was sometimes damaged when the shellfish were scraped off, and it took time and effort to replace the damaged sheet.
そこで、この考案はシートの表面に交換できる
着脱自在の保護シートを設けた汚濁防止膜を提供
することを目的とする。 Therefore, the object of this invention is to provide a pollution prevention film having a replaceable and removable protective sheet provided on the surface of the sheet.
上記の目的を達成するために、この考案はフロ
ートと、このフロートに上縁を支持させて垂れ下

けたループ群とから成る係着具を介して保護シー
トを着脱自在に張り付けて構成したものである。
In order to achieve the above object, this invention provides an anti-fouling membrane consisting of a float and a laterally long sheet suspended with its upper edge supported by the float. The protective sheet is removably attached to the protective sheet via a fastening device consisting of a group of hooks provided on one side of the overlapping surface and a group of loops provided on the other side.
シートの表面に係着具を介し保護シートを張り
付けて、上記保護シートによりシートに貝が付着
するのを防止する。
A protective sheet is attached to the surface of the sheet via a fastening tool, and the protective sheet prevents shellfish from adhering to the sheet.
また、保護シートに付着した貝により汚濁防止
膜の重量が増加してフロートの上周面が水面近く
迄降下或いは水面下に没入した場合、シートから
保護シートを取り外し、そしてシートに新しい保
護シート或は付着した貝を掻き落したのちの保護
シートを係着具を介し張り付ける。 In addition, if the weight of the anti-fouling membrane increases due to shellfish attached to the protective sheet and the upper circumferential surface of the float drops close to the water surface or sinks below the water surface, remove the protective sheet from the sheet and replace it with a new protective sheet or After scraping off the attached shellfish, attach a protective sheet using a fastener.
図において、Ａは汚濁防止膜である。 In the figure, A is a pollution prevention film.
上記の汚濁防止膜Ａは、フロート１と、このフ
ロート１に上縁を支持させて垂れ下げた横方向に
長いシート２とで構成され、上記フロート１は、
図示の場合、シート２の上縁全長に縫着等で取付
けてある筒状の袋部３内に浮部材４を収納した
が、シートの上縁に紐等を介しフロートを取付け
てもよい。 The anti-pollution film A is composed of a float 1 and a laterally long sheet 2 whose upper edge is supported by the float 1 and is hung down.
In the illustrated case, the floating member 4 is housed in a cylindrical bag 3 attached to the entire length of the upper edge of the sheet 2 by sewing or the like, but the float may be attached to the upper edge of the sheet via a string or the like.
また、シート２は、定尺のものを順次継ぎ足
し、かつ透水性のあるものが望ましい。 Further, it is desirable that the sheet 2 is made up of sheets of a fixed length and is water permeable.
５はシート２の表面にテープと、このテープの
重なり面一方に設けたフツク群及び他方に設けた
ループ群とから成る係着具６を介し着脱自在に張
り付けた保護シートである。 Reference numeral 5 denotes a protective sheet which is removably attached to the surface of the sheet 2 via a fastening device 6 consisting of a tape, a group of hooks provided on one side of the overlapped surface of the tape, and a group of loops provided on the other side.
また、保護シート５は、シート２と同様に透水
性を有し、かつ軽量のものが望ましく、さらに図
示のように保護シート５を取り扱いやすい面積に
裁断して用いると、交換時の作業性がよくなる。 In addition, the protective sheet 5 is desirably water-permeable and lightweight like the sheet 2, and if the protective sheet 5 is cut into an easy-to-handle area as shown in the figure, the workability during replacement will be improved. get well.
なお、図示の場合シート２の両面に保護シート
５を張り付けてあるが、潮流やその他の条件によ
り片面に付着する海域では、シート２の片面のみ
に保護シート５を張り付けてもよい。 In the illustrated case, the protective sheet 5 is attached to both sides of the sheet 2, but in sea areas where the protective sheet 5 adheres to one side due to tidal currents or other conditions, the protective sheet 5 may be attached only to one side of the sheet 2.
また、図示のように、シート２の丈方向全面に
保護シート５を張り付ける場合と、貝の最も付着
しやすい範囲のみに保護シート５を張り付ける場
合とがある。 Further, as shown in the figure, there are cases in which the protective sheet 5 is applied to the entire lengthwise direction of the sheet 2, and cases in which the protective sheet 5 is applied only to the area where shellfish are most likely to adhere.
上記のように構成すると、保護シート５のみに
貝が付着し、付着した貝による重量増加によりフ
ロートが定位置より沈降した場合、シート２から
貝の付着保護シート５を取り外し、そしてシート
２に予備の保護シート５或いは貝を掻き落した保
護シート５を張り付ける。 With the above configuration, if shellfish adhere to only the protective sheet 5 and the float sinks from its normal position due to the increased weight of the attached shellfish, the shellfish-adhering protective sheet 5 is removed from the sheet 2, and a spare is placed on the sheet 2. A protective sheet 5 or a protective sheet 5 with shellfish scraped off is pasted.
なお、保護シート５は、上述のシート２のみ以
外に第３図に示すようにフロート１の表面一部
に、或は第４図に示すようにフロート１の全部を
被うように取付けてもよい。 In addition, the protective sheet 5 can be attached not only to the sheet 2 described above, but also to a part of the surface of the float 1 as shown in FIG. 3, or to cover the entire float 1 as shown in FIG. good.
以上のように、この考案に係る汚濁防止膜によ
れば、フロートに上縁を支持させて垂れ下げたシ

As described above, according to the anti-fouling membrane of this invention, the protective sheet is attached to the surface of the hanging sheet with the upper edge supported by the float through the fasteners, so that shellfish can only be found on the protective sheet. When the shellfish adhesion has increased, the shellfish adhesion protective sheet can be removed from the sheet, and a spare protective sheet or a protective sheet with shellfish scraped off can be applied.
このため、手間のかかる海中でのシートに付着
した貝の掻き落し作業が不要になると共に、掻き
落しにともないシートが破れ、破れた部分のシー
トのみを交換しなければならないような不都合を
なくすることができる。 This eliminates the need for the labor-intensive work of scraping off shellfish adhering to the sheet underwater, and also eliminates the inconvenience of having to replace only the torn portion of the sheet when the sheet is torn during scraping. be able to.
また、保護シートに付着した貝の掻き落しは、
船上で行なうことができるので、掻き落し作業が
容易になると共に、機械を用いた掻き落しも可能
となる。 In addition, scraping off shellfish adhering to the protective sheet,
Since it can be carried out on board the ship, the scraping work becomes easier and it is also possible to scrape off using a machine.
さらに、係着具はテープと、このテープの重な
り面一方に設けたループ群及び他方に設けたフツ
ク群とで構成してあるので、保護シートの取付
