Isizathu sokuthi izibani zasemgwaqweni zelanga zithandwa kangaka ukuthi amandla asetshenziswa ekukhanyiseni avela kumandla elanga, ngakho-ke izibani zelanga azinawo ugesi onele. Yimiphi imininingwane yokuklama yeizibani zomgwaqo zelangaOkulandelayo yisingeniso salesi sici.
Imininingwane yomklamo wesibani somgwaqo selanga:
1) Umklamo wokuthambekela
Ukuze amamojula eseli lelanga athole imisebe yelanga eningi ngangokunokwenzeka ngonyaka, sidinga ukukhetha i-angle yokuthambekela efanele yamamojula eseli lelanga.
Ingxoxo mayelana nokuthambekela okuhle kwamamojula eseli lelanga isekelwe ezifundeni ezahlukene.
2) Idizayini engangeni moya
Ohlelweni lwezibani zasemgwaqweni zelanga, ukwakheka kokumelana nomoya kungenye yezinkinga ezibaluleke kakhulu esakhiweni. Ukwakheka okumelana nomoya kuhlukaniswe kakhulu izingxenye ezimbili, enye ukwakheka okumelana nomoya kwe-bracket yemojula yebhethri, kanti enye ukwakheka okumelana nomoya kwensika yesibani.
(1) Umklamo wokumelana nomoya we-solar cell module bracket
Ngokusho kwedatha yepharamitha yobuchwepheshe yemodyuli yebhethriumenzi, ingcindezi yokuphakama komoya engakwazi ukumelana nayo imodyuli yeseli lelanga ingu-2700Pa. Uma i-coefficient yokumelana nomoya ikhethwe njengo-27m/s (okulingana nesiphepho esingu-10 magnitude), ngokusho kwe-hydrodynamics engaqinile, ingcindezi yomoya ethwalwa yimodyuli yebhethri ingu-365Pa kuphela. Ngakho-ke, imodyuli ngokwayo ingamelana ngokugcwele nesivinini somoya esingu-27m/s ngaphandle kokulimala. Ngakho-ke, isihluthulelo okufanele sicatshangelwe ekwakhiweni ukuxhumana phakathi kwebracket yemodyuli yebhethri kanye nenduku yesibani.
Ekuklanyweni kohlelo lwezibani zasemgwaqweni olujwayelekile, ukuxhumana phakathi kwebhulakhethi yemojula yebhethri kanye nensika yesibani kuklanyelwe ukuthi kulungiswe futhi kuxhunywe ngensika yebholithi.
(2) Umklamo wokumelana nomoya we-isibani sesitrato
Imingcele yezibani zomgwaqo yilena elandelayo:
Ukuthambekela kwephaneli yebhethri A=15o ukuphakama kwesigxobo sesibani=6m
Dizayina bese ukhetha ububanzi bokushisela phansi kwesigxobo sesibani δ = 3.75mm isigxobo sokukhanya phansi ububanzi bangaphandle = 132mm
Ubuso bokushisela buwubuso obonakele bepali yesibani. Ibanga elisuka endaweni yokubala u-P wesikhathi sokumelana u-W ebusweni bokwehluleka kwepali yesibani kuya emgqeni wesenzo womthwalo wesenzo wephaneli yebhethri u-F epalini yesibani liyi
I-PQ = [6000+（150+6）/tan16o] × I-Sin16o = 1545mm=1.845m。 Ngakho-ke, umzuzu wesenzo somthwalo womoya ebusweni bokwehluleka kwesigxobo sesibani M=F × 1.845。
Ngokusho komklamo wesivinini somoya esiphezulu esivumelekile esingu-27m/s, umthwalo oyisisekelo wephaneli yezibani zasemgwaqweni zelanga ezingama-30W ezimbili u-480N. Uma ucabangela isici sokuphepha esingu-1.3, u-F=1.3 × 480 =624N.
Ngakho-ke, M=F × 1.545 = 949 × 1.545 = 1466N.m.
Ngokusho kokutholwa kwezibalo, isikhathi sokumelana sobuso bokuhluleka kwe-toroidal W=π × （3r2 δ+ 3r δ 2+ δ 3）。
Kule fomula engenhla, u-r ububanzi bangaphakathi bendandatho, u-δ ububanzi bendandatho.
Isikhathi sokumelana nendawo yokwehluleka W=π × (3r2 δ+ 3r δ 2+ δ 3)
=π × （3 × amakhulu ayisishiyagalombili namashumi amane nambili × 4+3 × amashumi ayisishiyagalombili nane × 42+43）= 88768mm3
=88.768 × 10－6 m3
Ukucindezeleka okubangelwa yisenzo somthwalo womoya ebusweni bokwehluleka = M/W
= 1466/（88.768 × 10－6） =16.5 × 106pa =16.5 Mpa<<215Mpa
Lapho, i-215 Mpa ingamandla okugoba ensimbi ye-Q235.
Ukuthululwa kwesisekelo kumele kuhambisane nemigomo yokwakha yokukhanyisa emgwaqweni. Ungalokothi unqume amakhona futhi usike izinto zokwakha isisekelo esincane kakhulu, ngoba isikhungo samandla adonsela phansi sesibani somgwaqo sizoba sizinzile, futhi kulula ukusilahla bese sibangela izingozi zokuphepha.
Uma i-engeli yokuthambekela kwesisekelo selanga iklanywe yaba nkulu kakhulu, izokwandisa ukumelana nomoya. I-engeli efanelekile kufanele iklanywe ngaphandle kokuthinta ukumelana nomoya kanye nezinga lokuguqulwa kokukhanya kwelanga.
Ngakho-ke, uma nje ububanzi nobukhulu besigxobo sesibani kanye ne-weld kuhlangabezana nezidingo zomklamo, kanye nokwakhiwa kwesisekelo okufanele, ukuthambekela kwe-solar module kunengqondo, ukumelana nomoya kwesigxobo sesibani akuyona inkinga.
Isikhathi sokuthunyelwe: Feb-03-2023
