The installation for incubating eggs and storing fish prelarvae includes a chamber 1, a lid 2, a funnel 6, a filter 7, a water discharge system, consisting of a water discharge connection 8, a protective net 9, a chamber balancing system, consisting of two rectangular containers 10, 14. Each container 10, 14 is made with a conical bottom 11, 15, a conical valve 12, 16, a rod 13, 17, a tube 18, semicircular supports 19 and two additional supports 20.
Exemplu de realizare a invenţiei Example of embodiment of the invention
Anterior începerii reproducerii peştelui, instalaţia pentru incubare se instalează pe un loc orizontal în aşa fel ca fundul camerei pentru incubare 1 să se sprijine pe tubul de suport 18 şi suporturile suplimentare 20, iar pâlnia 6 să se afle sub racordul vertical de alimentare cu apă 4 (fig. 1). Ulterior, prin supapa 5, racordul de alimentare 4, pâlnia 6 şi filtrul 7 apa pătrunde în camera pentru incubare 1. După umplerea parţială a camerei cu apă, pe fundul camerei se amplasează substratul 3 cu icre embrionate. La ridicarea nivelului apei în cameră până la racordul de evacuare 8, apa începe să se prelingă peste margini în recipientul dreptunghiular 14, iar supapele conice 12 şi 16 împiedică scurgerea apei din recipientul vertical 14. După umplerea recipientului dreptunghiular 14 cu apă, de sub fundul camerei pentru incubare 1 se înlătură suporturile suplimentare 20. Astfel se schimbă echilibrul camerei şi ea balansează pe tubul de suport 18 până ce marginea dreaptă de jos a camerei vine în contact cu suprafaţa orizontală (fig. 2). În urma acestui fapt are loc oscilarea straturilor de apă de deasupra substratului: astfel icrele embrionate sunt spălate cu apă, ceea ce contribuie la normalizarea respiraţiei şi înlăturarea substanţelor metabolice. De asemenea, după înclinarea instalaţiei, tija 17 scoate supapa conică 16 din contact cu fundul conic 15 şi evacuează apa din recipientul 14 şi respectiv din camera pentru incubare 1. Concomitent cu aceasta, racordul de alimentare cu apă 4 ajunge deasupra gurii recipientului 10 şi apa începe să pătrundă în acest recipient, iar supapa conică 12 împiedică scurgerea apei din recipient 10. Pe măsura deversării apei din camera pentru incubare 1 şi umplerea recipientului 10 cu apă, se schimbă echilibrul instalaţiei şi se înclină pe tubul de suport 18 până la atingerea marginii de jos a părţii stângi a camerei pentru incubare 1 cu suprafaţa orizontală (fig. 3). După aceasta, în camera pentru incubare au loc variaţii analogice ale straturilor de apă de deasupra substratului cu icre embrionate 3. În acest moment, după înclinarea camerei tija 13 scoate supapa 12 din contact cu fundul conic 11 şi apa se evacuează din recipient 10. Concomitent racordul de alimentare cu apă 4 se află deasupra gurii pâlniei 6 şi apa începe să pătrundă în camera pentru incubare 1, treptat umplând-o. Următoarele oscilaţii ale instalaţiei se desfăşoară în regim automat, iar periodicitatea lor se reglează prin schimbarea fluxului apei prin supapa 5. Before the fish breeding begins, the incubation facility is installed on a horizontal surface so that the bottom of the incubation chamber 1 rests on the support tube 18 and the additional supports 20, and the funnel 6 is located under the vertical water supply connection 4 (Fig. 1). Subsequently, through the valve 5, the supply connection 4, the funnel 6 and the filter 7, water enters the incubation chamber 1. After the chamber is partially filled with water, the substrate 3 with embryonated eggs is placed on the bottom of the chamber. When the water level in the chamber rises to the outlet connection 8, water begins to flow over the edges into the rectangular container 14, and the conical valves 12 and 16 prevent water from flowing out of the vertical container 14. After filling the rectangular container 14 with water, the additional supports 20 are removed from under the bottom of the incubation chamber 1. This changes the balance of the chamber and it swings on the support tube 18 until the lower right edge of the chamber comes into contact with the horizontal surface (Fig. 2). As a result, the water layers above the substrate oscillate: thus the embryonated eggs are washed with water, which contributes to the normalization of respiration and the removal of metabolic substances. Also, after tilting the installation, the rod 17 removes the conical valve 16 from contact with the conical bottom 15 and evacuates the water from the container 14 and from the incubation chamber 1, respectively. At the same time, the water supply connection 4 reaches above the mouth of the container 10 and water begins to enter this container, and the conical valve 12 prevents the water from leaking from the container 10. As the water is drained from the incubation chamber 1 and the container 10 is filled with water, the balance of the installation changes and it tilts on the support tube 18 until it touches the lower edge of the left side of the incubation chamber 1 with the horizontal surface (fig. 3). After this, in the incubation chamber, analogous variations of the water layers above the substrate with embryonated eggs 3 occur. At this moment, after tilting the chamber, the rod 13 removes the valve 12 from contact with the conical bottom 11 and the water is discharged from the container 10. At the same time, the water supply connection 4 is located above the mouth of the funnel 6 and water begins to enter the incubation chamber 1, gradually filling it. The following oscillations of the installation take place in automatic mode, and their periodicity is regulated by changing the water flow through the valve 5.
Pentru funcţionarea instalaţiei în regim de stocare a prelarvelor, camera pentru incubare 1 este fixată în poziţie orizontală, după cum este indicat în fig. 1, asigurându-se alimentarea continuă cu apă a camerei pentru incubare prin racordul de alimentare 4, pâlnia 6 şi filtrul 7. Evacuarea apei se efectuează prin racordul 8 cu plasă de protecţie 9, împiedicând scurgerea prelarvelor din camera pentru incubare. Apa uzată prin racordul de evacuare a apei 8 pătrunde în recipientul dreptunghiular 14, iar din el în reţeaua de canalizare. For the operation of the installation in the prelarvae storage mode, the incubation chamber 1 is fixed in a horizontal position, as indicated in Fig. 1, ensuring continuous water supply to the incubation chamber through the supply connection 4, funnel 6 and filter 7. Water is discharged through the connection 8 with a protective mesh 9, preventing the prelarvae from leaking out of the incubation chamber. Waste water through the water discharge connection 8 enters the rectangular container 14, and from there into the sewage system.
