I-Laiwu Steel Group Zibo Anchor Chain ikuthatha uqonde izinhlobo ezimbalwa zemikhumbi yokudoba ejwayelekile

1. Bhanqa isikebhe sokudonsa

ikakhulukazi ibamba izikole zezinhlanzi ezisezingeni eliphakathi nendawo, ezisebenza ngaphakathi kwamamitha ayi-100 ukujula kwamanzi.Isivinini sokudonsa singamafindo ama-3.Idonswa nomsinga esimweni sezulu esihle, futhi idonswa nomoya ngosuku olunomoya.Icishe ibe ngamamitha angu-1 000 ukusuka lapho udonsa khona uye emsileni wenethi.I-trawler ayikwazi ukuma ngokushesha phakathi nokusebenza.Uma ugwema ukudonsa kabili, kufanele ushayele kude namamayela angaphezu kuka-0.5 ukusuka ngemuva komkhumbi noma ohlangothini olungaphandle lwemikhumbi emibili.Lapho lezi zikebhe ezimbili zitholakala zibeka amanetha azo zibheke kude, kufanele ziwugweme umoya namagagasi.

2. I-trawler eyodwa (ukudonsa umsila noma i-beam tow)

Ukudonsa umsila akuthintwa amaza olwandle, isivinini sokudonsa singamafindo ama-4 kuye kwayisi-6, futhi sisebenza ekujuleni okungaphezu kwamamitha ayi-100.Uma ugwema ukudonsa okukodwa, gcina imayela elingu-1 le-nautical kude nomsila.Uma isikebhe esidonsayo sitholwa singazinzile, kusho ukuthi sibeka noma sihlehlisa inethi.

3. Sakaza (gill) isikebhe sokudoba inetha

Drift inetha elingunxande, lithembele emsebenzini wokuntanta namasinki ukuze kumiswe umthunzi emanzini.Ukuze ubambe izinhlanzi eziphakathi nendawo kanye ne-pelagic, amanetha ngokuvamile ahoxiswa ekuseni noma kusihlwa.Lapho inetha ibekwa, ukugeleza komoya kuvame ukuba nomoya owehlayo, futhi inetha elikhulu lokukhukhuleka linwebeka ngaphezu kwamamayela angu-2 we-nautical.Igwebu noma ingilazi iyantanta kanye namabhuya amaningi amancane angabonakala emini, futhi amafulege amancane atshalwa ngezikhathi ezithile.Isibani sebhethri esikhanyayo silengiswa esigxotsheni ekupheleni kwenethi ebusuku.Ngemva kokubeka inetha, isikebhe nenetha kukhukhuleka nomoya, futhi inetha libheke ngakumnsalo.Lapho ugwema, kufanele udlule ngemuva komkhumbi.

4. Isikebhe sokudoba i-Purse Seine

Indlela yokubamba izinhlanzi ze-pelagic usebenzisa inetha elikhulu eliyiribhoni elide.Ngokuvamile ukukhanya kuheha izinhlanzi, futhi phakathi nosuku umugqa wokubuka muhle, futhi inetha lintanta phezu kwamanzi lingabonakala.I-purse seine icishe ibe ngamamitha ayi-1000 ubude, futhi isetshenziswa kakhulu ezindaweni zokudoba ezinobubanzi bamanzi obungamamitha angama-60 kuye kwangama-80.Isikebhe sokudoba siseduze nenetha lapho inetha lihoxiswa.I-single-boat purse seine ivamise ukubeka inethi ngakwesokunxele.Umoya ugeleza ngakwesokudla.Ukucupha okulula cishe amahora ama-3, kanti inetha cishe ihora elingu-1.Uma ugwema, gcina amamayela angu-0.5 e-nautical kude nohlangothi lomoya ongenhla namagagasi.

5. Isikebhe sokudoba inetha

Inetha liyithuluzi lokudoba elingashintshi, elisebenza emanzini angashoni eduze nogu.I-net frame isebenzisa izinqwaba ukuvula inetha lapho kusetshenziswa ama-tidal rapids.Lapho ukugeleza kuncipha, inetha liqala.

6. Isikebhe sokudoba ngomugqa omude

Ubude bomugqa we-trunk ngokuvamile bungamamitha ayi-100 ukuya kumamitha angama-500.Isikebhe sokudoba ngomugqa omude sisebenzisa i-sampan eyehlisiwe ukubeka izinto zokudoba, futhi izintambo zokudoba zidedelwa ngemuva komkhumbi wokudoba futhi zifakwe amahange noma amatshe acwile.Uma uvika, vele udlule imayela elingu-1 le-nautical kusukela ngemuva.
