Description

Wytwarzanie baniek gazowych bezposrednio w miejscu poczatku przegrody-kurtyny pozwala na równomierne rozmieszczenie zarówno baniek jak i na równomierne ich nasilenia. Elektryczny spo¬ sób wytwarzania — przez elektrolize — daje sie szczególnie latwo elektrycznie sterowac, regulo¬ wac, zmieniac, umozliwiajac wytworzenie dowol¬ nej — w praktyce — sieci baniek, w przegrodzie- kurtynie. Szczególnie korzystna, acz uboczna, zale¬ ta jest okolicznosc uzdatniania i polepszania sro¬ dowiska wodnego przez wprowadzenie don tlenu.Przedmiot wynalazku jest przedstawiony w przy¬ kladzie wykonania, uwypuklajacym istote rozwia¬ zania i wazniejsze dane techniczne.W1 celu ustawienia dlugiej przegrody dla ryb przewidziano wytworzenie od dna do powierzchni przegrody-kurtyny z baniek gazowych, o dlugosci Druk. 4 7,2 km. Na dnie ulozony zostal kabel morski z za¬ instalowanymi i zamocowanymi don zestawami elektrod. Te zestawy, w postaci ciagów par elek¬ trod, których obciazeniem jest sam kabel morski, 5 a których usplawnieniem sa * odpowiednie plywaki, sa dolaczone do kabla. Kolejne zestawy sa dola¬ czone do dwóch, z trzech roboczych zyl kabla tak, iz nastepny zestaw dolaczony jest do jednej z zyl, do której dolaczony jest zestaw poprzedni i do trze- 10 ciej zyly, wolnej uprzednio. Kabel jest zasilany dwustronnie, bedac polaczony innymi kablami ze zródlem napiecia w znany sposób.Zasilanie nastepuje poprzez wielofazowy stero¬ wany prostownik. Odpowiednio kolejno w czasie 15 doprowadzane sa impulsy pradu do kolejnych ze¬ stawów z parami elektrod. W wyniku przeplywu impulsów pradu przez osrodek wodny miedzy od¬ powiednimi parami elektrod, na tych elektrodach wydzielaja sie jony tlenu i jony wodoru, z których 20 powstaja banki tlenu i banki wodoru. Jednoczes¬ nie powstajace rzedy baniek gazowych wyplywa¬ ja w wyniku dzialania sil wyporu ku górze. Po¬ wstaje przegroda-kurtyna z baniek gazowych. PL PLGenerating gas bubbles directly at the beginning of the partition-curtain allows for an even distribution of both the bubbles and their uniform intensity. The electric method of production - by electrolysis - is particularly easy to electrically control, regulate, and change, making it possible to produce any - in practice - bubble network in the partition-curtain. Particularly advantageous, albeit a side effect, is the fact of treating and improving the aquatic habitat by introducing oxygen don. The subject matter of the invention is presented in an embodiment that highlights the essence of the solution and the most important technical data. it was planned to create a partition-curtain of gas bubbles from the bottom to the surface, Printing length. 4, 7.2 km. At the bottom there is a sea cable with sets of electrodes installed and fixed to it. These sets, in the form of strings of pairs of electrodes, the load of which is the sea cable itself, and which are matched by appropriate floats, are attached to the cable. The next sets are attached to two of the three working wires of the cable so that the next set is attached to one of the wires to which the previous set is attached and to the third, free previously. The cable is fed from both ends, being connected to the voltage source by other cables in a known manner. The power is supplied by a multi-phase controlled rectifier. Correspondingly successively in time, current pulses are applied to the successive electrode pairs. As a result of the flow of current pulses through the water medium between the respective electrode pairs, oxygen ions and hydrogen ions are released on these electrodes, from which oxygen banks and hydrogen banks are formed. The simultaneously formed rows of gas bubbles flow out by the upward action of buoyancy forces. A partition-curtain made of gas bubbles is formed. PL PL

Claims

1. Claims 1. A method of intensifying the catch of fish by their initial concentration, consisting in separating the evrr., The area with fish from which they then emerge from the rest of the water area, a barrier-curtain of gas bubbles, characterized by the fact that on the lower periphery of the molded partition-curtain there are sets of electrodes electrically connected to the source of the current and the current is passed through the water of the medium, as a result of which oxygen and hydrogen are released on the electrodes, creating barriers a curtain extends from the lower periphery of the partition 40 to the water surface.

2. The method according to claim The method of claim 1, wherein current pulses are applied intermittently to the electrode pairs of the electrode pairs (with no current flow) to form bubbles that coagulate by flowing into the larger gas banks.

3. The method according to p. The method of claim 1 or 2, characterized in that the current pulses are applied successively, alternately, to the sets of electrode pairs to obtain the proper distribution of the bubbles in the partition-curtain and to obtain a uniform load on the current source, the sum of these pulses.

4. The method according to p. The method of claim 2, wherein the size of the pulse interruptions is determined according to the catch method, species and size of the fish, 55 for their selective distribution. 2521 10/15/74. 105 copies and 10 zlotys PL PL
