Engineering Analysis: Kev Xaiv Lub Hauv Paus rau Loj -Scale Photovoltaics
Hauv av -mounted photovoltaic systems siv lub hnub ci hauv av ntsia hlau lub hauv paus los yog cam khwb cia- hauv - tso pob zeb ua ke los tswj axial compression thiab lateral shear loads. Rau kev siv hluav taws xob- nplai cov phiaj xwm, cov ntsia hlau hauv av ua tiav lub voj voog kev teeb tsa ntawm 5-10 feeb ntawm ib chav, txo qis kev ua haujlwm hnyav piv rau 24-48 teev kho lub sijhawm uas yuav tsum tau ua rau pob zeb. Kev xaiv yuav tsum yog raws li kev faib tawm hauv av (ASTM D2487), shear lub zog tsis muaj zog, thiab qhov chaw-cov peev txheej tshwj xeeb corrosive raws li tau hais los ntawm ISO 12944.
Kev sib piv cov qauv kev ua tau zoo thiab kev soj ntsuam tus nqi muag khoom
Qhov kev xaiv ntawm cov ntsia hlau hauv av thiab cov pob zeb ua vaj tse hloov pauv qhov project BoP (Balance of Plant) cov nqi. Thaum cov pob zeb ua kom muaj qhov hnyav tuag siab rau kev txhawb nqa, nws lub installation yuav tsum muaj kev thauj mus los hnyav rau cov tsheb sib xyaw ua ke thiab cov khoom siv khawb. Hnub ci hauv av ntsia hlau siv siab - tawm lub zog steel (Q235 / Q355) nrog kub-dip galvanization ($ \\ge $ 80μm thickness) kom ntseeg tau tias lub neej ntev nyob rau hauv cov av hnyav.
| Metric | Solar Ground Screw | Qhob Base |
| Lub Sijhawm Txhim Kho | 5–10 feeb | 24-48 teev (kho) |
| Av xav tau | Cohesive/Tsis yog-cohesive | Kev siv dav dav |
| Kev tiv thaiv corrosion | Kub-dip galvanized ($\\ge$80μm) | N/A (Reinforced qhob) |
| Kev khawb av | Tsis muaj | Yuav tsum tau |
| Environmental Impact | Kev cuam tshuam tsawg kawg nkaus | Kev ntxhov siab heev |
Geotechnical Suitability thiab Load-Bearing Optimization
Ground screw foundations are subject to pull-out and lateral load tests in compliance with AS/NZS 1170.2 standards. In high-wind scenarios (wind loads >60m / s), lub geometry ntawm cov ntsia hlau xov yuav tsum sib phim rau cov av sib txhuam lub kaum sab xis ($\\phi$) thiab cohesion (c). Hloov pauv, cov hauv paus pob zeb yog nyiam nyob rau hauv pob zeb los yog xoob heev, tsis yog -cov av cohesive strata qhov twg cov ntsia hlau nkag mus rau lub cev los ntawm cov pob zeb los yog tsis muaj kev sib txhuam tsis txaus.
Thaum cov av pH nyob nruab nrab ntawm 5 thiab 9, tus qauv galvanized steel yog txaus. Txawm li cas los xij, rau cov chaw uas muaj cov tshuaj chloride lossis sulfate siab, cov khoom siv tiv thaiv ntxiv lossis cov hlau tsis muaj steel (SUS304) yuav tsum ua kom tau raws li 25-xyoo tsim lub neej expectancy.
Environmental and Operational Advantages of Pile-Kev tsav tsheb
Kev siv pawg- tsav lub hnub ci tshem tawm qhov kev xav tau loj - lub ntiaj teb txav, txo qhov chaw ntawm cov pa roj carbon hneev taw thiab cov kev cai tswj xyuas dej ntws. Tsis zoo li cov pob zeb, uas nyob hauv qhov chaw ntim qhov tseem ceeb, cov ntsia hlau steel tso cai rau cov nroj tsuag rov qab los tom qab- txhim kho. Los ntawm kev xav txog kev ua neej nyob, lub peev xwm tshem tawm thiab rov ua dua cov khoom siv hlau thaum kawg ntawm 25- xyoo kev pabcuam raws li cov qauv kev lag luam ncig zoo dua li cov pob zeb uas tsis tuaj yeem rov ua dua.
Cov lus nug nquag
Dab tsi yog qhov rub - tawm lub peev xwm ntawm Bristar hnub ci hauv av screws?
+
-
Peb tus qauv ntsia hlau yog tsim los tiv thaiv axial rub- tawm ntawm qhov hnyav ntawm 15kN txog 40kN, nyob ntawm chav kawm av thiab qhov tob tob. Cov nqi tseeb raug txiav txim los ntawm - qhov chaw thauj khoom kuaj xyuas kom ua raws li cov cai hauv zos engineering.
Yuav ua li cas Bristar tswj tus MOQ rau cov lag luam wholesale hnub ci qauv?
+
-
Raws li cov chaw tsim khoom ncaj qha, peb txhawb cov ntim hloov tau yooj yim. Rau cov qauv catalog qauv, peb ua raws li cov khoom me me, thaum kho cov pawg - tsav tsheb rau kev siv hluav taws xob loj - cov phiaj xwm loj ua raws li kev tsim ua kom zoo los txo cov nqi tsev.
Puas yog av screws haum rau cov av corrosive heev?
+
-
Yog lawm. Peb siv cov txheej txheem kub -dip galvanization nrog qhov tsawg kawg nkaus txheej thickness ntawm 80μm. Rau cov chaw uas muaj salinity heev los yog acidity, peb muab tshwj xeeb coatings los yog hnyav -cov dej num steel specifications los xyuas kom meej tus qauv tswj nws cov yield zog rau lub hom phiaj 25-xyoo kev pab cuam lub neej.
