Nakuba ngabelane ngolwazi oluthile lwezindlu zokugcina izithombo ezihlakaniphile ezihlokweni eziningi ezedlule, izethameli zolwazi oludumile lwesayensi zilinganiselwe.Ngethemba ukuthi ungabelana ngezindatshana zesayensi ezengeziwe ezizwakala zilungile futhi zinenjongo.Izolo, sithole iqembu lamakhasimende.Ziyizindawo zokugcina izithombo ezihlakaniphile esigabeni sesibili sepaki yezolimo.Ngenxa yokuthi babengazi ukuthi bazokuthola kanjani ukwakhiwa kwesigaba sokuqala, babengebona ochwepheshe.Ngakho-ke, i-greenhouse ayilungile.Ucabanga ukuthi umholi wezolimo we-Bureau of Agriculture akaluqondi lolu hlobo lwe-greenhouse osekuyiminyaka eyisikhombisa noma eyisishiyagalombili luvela, okubonisa ukuthi ukuthandwa kwesayensi yethu akwanele.Namuhla, ngizokunikeza incazelo eningiliziwe kusukela ekucutshungulweni kwezinto ezintsha zohlaka lwe-smart greenhouse.
1.I-Smart greenhouse skeleton greenhouse greenhouse, i-greenhouse engineering, imodeli yepayipi yomkhiqizi we-greenhouse skeleton
Njengamanje, izinto ezisetshenziswa kakhulu zensimbi zohlaka lwezindlu zokugcina izithombo ezihlakaniphile zibandakanya amashubhu ayisikwele, amashubhu ayindilinga kanye nemishayo eyinhlanganisela.Ishubhu yesikwele: ngokuvamile isetshenziselwa ukuphakama kwezindlu zokugcina izithombo ezihlakaniphile.Ukucaciswa okujwayelekile kungu-150*150, 120*120*100*100, 50*100 noma amanye amashubhu ayisikwele amakhulu.Izinti zokubopha ze-greenhouse zisebenzisa amashubhu amancane angama-square afana nama-50*50.Ishubhu eliyindilinga: Ishubhu eliyindilinga le-smart greenhouse lisetshenziswa kakhulu izinduku zokushayela ku-sunshade wangaphakathi nangaphandle kanye nohlelo lwangaphakathi lokufakwa kwe-thermal insulation drive.
2.Ubuchwepheshe processing of ezihlakaniphile control greenhouse skeleton pipe
Ubuchwepheshe bokucubungula obuyinhloko bekholomu ye-canopy, ugongolo lokulungisa, kanye ne-herringbone beam ukusika nokugxiviza ishubhu yesikwele eyenziwe ngokwezifiso ye-hot-dip galvanized ngokosayizi odwetshiwe.
Inqubo yokucubungula ye-greenhouse beam isebenzisa i-clarinet welding, ngokuvamile eyakhiwe ngamapayipi aphansi nangaphezulu, izisekelo ezithambekele maphakathi kanye nezisekelo eziphakathi.
3.Ikhwalithi yepayipi nezidingo zenqubo
Inani lepayipi lensimbi eliphehliwe likhulu, umphumela wokulwa nokugqwala ulungile, futhi impilo yesevisi yinde.Ngokuvamile, impilo evamile yesevisi yekhwalithi yamapayipi ensimbi ekusetshenzisweni okuvamile okungenani iminyaka eyi-10, futhi amapayipi ensimbi asezingeni eliphezulu emikhiqizo emikhulu ngokuvamile aneminyaka eyi-15-20, nokusebenza kahle kokulungisa, ukugqamisa okukhulu, ngisho nempilo yesevisi. iminyaka engu-30.
Izinto ezithinta ikhwalithi yamapayipi ensimbi
Inani lamapayipi ensimbi athambekele kakhulu ekungeneni kwe-air oxidation nokugqwala, ngakho-ke izinyathelo zokulwa nokugqwala kufanele zithathwe.Njengamanje, isilinganiso esisetshenziswa kakhulu sokulwa nokugqwala siwukwenza i-galvanize ubuso bepayipi lensimbi, elinquma ikhono lokulwa nokugqwala.I-galvanizing eyengeziwe, inqubo engcono kakhulu kanye nekhwalithi engcono yepayipi yensimbi.Kodwa lapho amagalani engeziwe, izindleko ziphezulu.
Ukuqina kodonga lwepayipi lensimbi, ipayipi lensimbi liyilungu lesakhiwo esigcizelelwe, futhi kufanele lidingeke ukuze kuhlaziywe ukucindezeleka.Ukuqina kodonga lwamapayipi epayipi lensimbi, ukusebenza kwamandla kuzoba ngcono kanye nokuphathwa kwekhwalithi okungcono, kodwa ukuthuthukiswa kuye ngokuthi Ukuqina kodonga lwamapayipi, izinga lezindleko liyakhuphuka.
Incazelo yenqubo yepayipi lensimbi elinamandla
I-Hang plating: Iphinde ilenge i-plating, enekhwalithi enhle, i-zinc ephezulu kanye nekhono eliqinile lokulwa nokugqwala.Ukugeleza kwenqubo kucishe kube kanje: ipayipi lensimbi lifakwe emanzini anosawoti.Ngemva kokuba ukungcola okusepayipini lensimbi kugezwe, ipayipi lensimbi licwiliswa kubhavu we-zinc.Ngemva kwemijikelezo eminingana yokuphakamisa imizuzwana engaphezu kweshumi, iyakhishwa futhi ipholiswe.Okuqukethwe kwe-zinc kwepayipi lensimbi kufinyelela ku-400 ~ 600 amagremu, futhi impilo yesevisi yepayipi lensimbi engu-30.Njengamanje, inani elikhulu lamapayipi ensimbi asetshenziswayo enqubweni yokufaka uthayela kumaphrojekthi amakhulu kazwelonke, izitimela ezihamba ngesivinini esiphezulu nengqalasizinda, kanye nezingxenye ezinkulu ezifana nezigxobo ezindlini zokugcina izithombo.
I-Blow plating: Idinga ukucwiliswa bese icwiliswa kubhavu we-zinc, kodwa ngemva kokuphakanyiswa, izodlula kudivayisi.I-zinc ayixhunyiwe ngokuphelele kwipayipi yensimbi.I-zinc eyeqile iyelashwa, kodwa umthamo wale zinc uphansi kancane.Izinga lamanje lingama-200 amagremu Cishe kabili umthamo we-zinc ohlelweni lokulenga i-zinc, izindleko zepayipi lensimbi kule nqubo ziphansi, impilo yesevisi ingafinyelela eminyakeni engu-15 kuya kwengu-20, futhi kubiza izindleko.Kuyinqubo evamile yokufaka ama-galvanizing.
Okwesine, izindleko ze-smart greenhouse framework
Ngokucaciswa kwezinto ezihlukile nezindlela zokucubungula, izindleko zohlaka lwamathambo abamba ukushisa lusukela kumayuan angama-85 kuye kwangama-120.Izindleko zohlaka olunothayela lwe-hot-dip noma i-hot-dip galvanized frame iphakathi kuka-85 yuan no-120 yuan.
