【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、例えば水力発電所用の取水導水路等水中に構
築された構造物において、特に構造物の水面付近の水中
の壁面にとびげら等の生物が付着するのを防止するよう
にした生物付着防止装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is particularly applicable to structures built underwater, such as water intake channels for hydroelectric power plants, in which spikes are installed on underwater walls near the water surface of the structure. This invention relates to a biological adhesion prevention device that prevents the adhesion of biological organisms such as.
一般に、取水口近くの取水路の壁面にとびげらが付着す
る過程として、つぎの５つの過程が推察され６゜
■ 空中から壁面に止まった成虫が壁伝いに水中の壁面
に分布し、産卵を行う。In general, the following five processes are assumed to be involved in the attachment of spiny flies to the wall of the intake channel near the water intake.6゜■Adults land on the wall from the air, distribute along the wall to the underwater wall, and spawn. I do.
■ 空中から着水した成虫が遊泳もしくは流されて壁面
に達し、その後壁伝いに水中の壁面に分布し、産卵を行
う。■ Adults land on water from the air and swim or are swept away to reach a wall, then follow the wall and distribute themselves on the underwater wall, where they lay eggs.
■ 空中から着水した成虫が潜水して行き、水中を遊泳
しながら壁面の任意の位置に達し、産卵を行う。■ Adult insects land in the water from the air, dive, swim underwater, reach a desired position on the wall, and lay eggs.
■ 空中から着水した成虫が潜水して行くが、比較的浅
い水深で自刃もしくは流されて壁面に到達し、産卵を行
う。■ Adults land in the water from the air and dive into the water, but at relatively shallow depths, they either self-cut themselves or are swept away and reach the wall, where they lay eggs.
■ 上流の渓流において醇化した幼虫が流れに乗り川を
下った後、水路壁面に到達してそのまま分布する。■ The larvae that become molten in the upstream mountain stream ride the current and go down the river, then reach the waterway wall and are distributed as they are.
つぎに、前記付着過程を大別すると、つぎの２つの形態
に要約できる。Next, the adhesion process can be roughly classified into the following two types.
Ａ 成虫は歩行、遊泳、流されるにかかわらず、−旦水
面近くの壁面にたどシつき、その後壁伝いに分布して行
き産卵を行う。A: Regardless of whether they are walking, swimming, or being washed away, the adult insects land on a wall near the surface of the water, and then spread out along the wall and lay eggs.
Ｂ 成虫においては水中を自在に潜水し、幼中において
は水路を流されながら壁面の任意の位置に付着し、その
後、産卵もしくは成長して行く。B: Adults dive freely in water, and larvae attach themselves to arbitrary positions on walls while being washed away in waterways, and then spawn or grow.
なお、この形態はとびげら以外の昆虫等生物についても
同様である。Note that this form also applies to living things such as insects other than spiny flies.
そして、とびげら等の付着厚さは１０α以上にも及び、
しかも取水路も数ムに及ぶため、取水損失が起９発電量
が減少する。The thickness of the adhesion of spiny thorns, etc. is over 10α,
Furthermore, since the intake channel is several meters long, water intake losses occur and the amount of power generated decreases.
そのため、従来は前記付着生物を機械的１人的作業によ
り除去してめる。Therefore, conventionally, the attached organisms are removed mechanically and by one person.
従来、前記付着生物の除去を機械的１人的作業によυ行
っているため、実大な費用と時日を要するという問題点
がある。Conventionally, the removal of the attached organisms has been carried out mechanically and by one person, which poses the problem of requiring a considerable amount of cost and time.
本発明は、前記の点に留意し、とひげら等の生物の付着
を簡単に防止できる生物付着防止装置を提供することを
目的とする。The present invention has been made with the above-mentioned points in mind, and an object of the present invention is to provide a biological adhesion prevention device that can easily prevent the adhesion of living organisms such as whiskers.
