Chikonzero nei marambi emumugwagwa ezuva achifarirwa zvakanyanya ndechekuti simba rinoshandiswa pakuisa mwenje rinobva kusimba rezuva, saka marambi ezuva haana magetsi akawanda. Ndezvipi zvinhu zvakaita semagadzirirwo emarambi aya?marambi emumugwagwa ezuvaZvinotevera ndizvo zvinotiudza nezvenyaya iyi.
Ruzivo rwekugadzira rambi remumugwagwa rezuva:
1) Dhizaini yepfungwa dzinoenderana
Kuti ma solar cell modules agamuchire mwaranzi yakawanda yezuva mugore, tinofanira kusarudza kona yakatsetseka yakakodzera yema solar cell modules.
Kukurukurirana pamusoro pekunamira kwakanaka kwema solar cell modules kwakavakirwa pamatunhu akasiyana.
2) Dhizaini inodzivirira mhepo
Muhurongwa hwemwenje wezuva, dhizaini yekudzivisa mhepo ndeimwe yenyaya dzakakosha muchimiro. Dhizaini yekudzivisa mhepo yakakamurwa kuita zvikamu zviviri, chimwe idhizaini yekudzivisa mhepo yebhatiri module bracket, uye chimwe idhizaini yekudzivisa mhepo yedanda remwenje.
(1) Dhizaini yekudzivirira mhepo ye solar cell module bracket
Zvichienderana nedata rehunyanzvi remota yebhatirimugadziri, kumanikidzwa kwemhepo kunokwidzwa ne solar cell module kunogona kutsungirira i2700Pa. Kana coefficient yekudzivirira mhepo yakasarudzwa se27m/s (yakaenzana nedutu guru re10), zvichienderana ne non-viscous hydrodynamics, kumanikidzwa kwemhepo kunotakurwa ne battery module i365Pa chete. Nokudaro, module pachayo inogona kutsungirira zvakakwana kumhanya kwemhepo kwe27m/s pasina kukuvara. Saka, chinhu chikuru chekufunga nezvacho mukugadzira ndechekubatana kuripo pakati pe battery module bracket ne rambi remwenje.
Mukugadzirwa kwemarambi emumugwagwa, kubatana kuripo pakati pebhatiri module bracket nerambi rakagadzirwa kuti rigadziriswe uye ribatanidzwe nebhaudhi.
(2) Dhizaini yekudzivirira mheporambi remugwagwa
Magadzirirwo emwenje yemugwagwa ndeaya anotevera:
Kurerekera kwebhatiri A=15o kukwirira kwedanda rerambi=6m
Dhizaina uye sarudza upamhi hweweld pasi pedanda rerambi δ = 3.75mm dayamita yekunze yedanda rechiedza pasi = 132mm
Pamusoro pe weld panenge pakakuvara pedanda rerambi. Chinhambwe kubva panzvimbo yekuverenga P ye resistance moment W pamusoro pe dambi rerambi kusvika pamutsetse we action load ye battery panel F padanda rerambi ndeche
PQ = [6000+(150+6)/tan16o] × Sin16o = 1545mm=1.845m。 Nokudaro, nguva yekushanda kwemhepo pamusoro pechinokundikana chedanda rerambi M=F × 1.845。
Zvichienderana nekugadzirwa kwemhepo inomhanyisa kumhanya kwepamusoro inobvumirwa ye27m/s, mutoro wekutanga we30W double-head solar street lamp panel i480N. Tichifunga nezvekuchengetedza kwe1.3, F=1.3 × 480 =624N.
Saka, M=F × 1.545 = 949 × 1.545 = 1466N.m.
Zvichienderana nekwakabva masvomhu, nguva yekuramba kwenzvimbo yekukundikana kwetoroidal W=π × （3r2 δ+ 3r δ 2+ δ 3）。
Mufomura iri pamusoro apa, r idhayamita yemukati yerin'i, δ ihupamhi hwerin'i.
Kuramba nguva yekutadza kwepasi W=π × (3r2 δ+ 3r δ 2+ δ 3）
=π × （3 × mazana masere nemakumi mana nemaviri × 4+3 × makumi masere nemana × 42+43）= 88768mm3
=88.768 × 10-6 m3
Kushushikana kunokonzerwa nekushanda kwemhepo panguva yekukundikana kwenzvimbo = M/W
= 1466/（88.768 × 10－6） =16.5 × 106pa =16.5 Mpa<<215Mpa
Kupi, 215 Mpa ndiyo simba rekukombama resimbi yeQ235.
Kudururwa kwehwaro kunofanirwa kuenderana nezvinodiwa pakuvaka mwenje yemugwagwa. Usambofa wakacheka makona kana kucheka zvinhu kuti uite hwaro hudiki, nekuti pakati pesimba remwenje wemugwagwa hapazogadzikane, uye zviri nyore kurasa marara uye kukonzera tsaona dzekuchengetedza.
Kana kona yekutsvedza yerutsigiro rwezuva yakagadzirwa yakakura zvakanyanya, inowedzera kupesana nemhepo. Kona yakakodzera inofanira kugadzirwa pasina kukanganisa kupesana nemhepo uye mwero wekushanduka kwechiedza chezuva.
Saka, chero bedzi dhayamita nehukobvu hwedanda remwenje ne weld zvichizadzisa zvinodiwa pakugadzira, uye kuvakwa kwenheyo kwakakodzera, solar module inclination ine musoro, kuramba kwedanda remwenje hakuna dambudziko.
