Iyo mhepo inopikisa dhizaini yebhatiri chikamu chebhureki uye positi yemwenje.
Kare, shamwari yangu yakaramba ichindibvunza nezve mhepo uye kusamira kwemagetsi emagetsi ezuva. Iye zvino isu tinogonawo kuita kuverenga.
Mwenje yeSolar Street Mwenje Mumagetsi ezuva remumugwagwa, nyaya yakakosha ndeyekupikisa dhizaini. Iyo mhepo inopikisa dhizaini inonyanya kukamurwa kuita zvikamu zviviri zvikuru, imwe ndeyekupikisa dhizaini yebhatiri chikamu chebhatiri, uye imwe yacho dhizaini yekupokana nemhepo yerambi positi.
Zvinoenderana neiyo tekinoroji parameter data yevagadziri vebhatiri module, solar cell module inogona kumirisana nekumanikidza kwe2700Pa. Kana mhepo inopikisa coefficient yakasarudzwa kuva 27m / s (yakaenzana nedutu regumi-level), maererano ne-non-viscous fluid mechanics, mhepo yemhepo yegungano rebheteri inongova 365Pa chete. Naizvozvo, chikamu pachayo chinogona kumira 27m/s mhepo yekumhanya pasina kukuvara. Naizvozvo, kutarisisa kwakakosha mukugadzira ndiko kubatana pakati pebhatiri rekubatanidza bhatiri uye positi yemwenje.
Muchigadziro chezuva rechiedza chemugwagwa, dhizaini yekubatanidza yebhatiri yekubatanidza bhatiri uye chigadziko chemwenje chakanyatsobatanidzwa ne bolt rod.
Windproof dhizaini yemugwagwa wemwenje
Iwo ma parameter e solar street light ndeaya anotevera:
Panel tilt angle A = 16o danda kureba = 5m
Iyo solar street light mugadziri dhizaini inosarudza hupamhi hwekusonesa seam pazasi pechigadziko chemwenje δ = 4mm uye dhayamita yekunze yepasi pechigadziko chemwenje = 168mm
Kumusoro kwe weld ndiko kuparadza pamusoro pechigadziko chemwenje. Chinhambwe kubva pachiyero chekuverenga P chenguva yekupikisa W yekuparadza pamusoro pedanda remwenje kune mutsara wekuita wepaneti mutoro F inogamuchirwa nedanda remwenje ndeye PQ = [5000+(168+6)/tan16o]×Sin16o = 1545mm = 1.545m. Nokudaro, nguva yekutakura kwemhepo pamusoro pekuparadzwa kwechigadziko chemwenje M = F × 1.545.
Zvinoenderana nedhizaini yakakura inobvumidzwa kumhanya kwemhepo ye27m/s, iyo yakakosha mutoro we2 × 30W mbiri-mwenje solar street light panera ndeye 730N. Tichifunga nezvekuchengetedzwa kwe1.3, F = 1.3 × 730 = 949N.
Saka, M = F × 1.545 = 949 × 1.545 = 1466N.m.
Zvinoenderana nekutorwa kwemasvomhu, nguva yekupokana yedenderedzwa remhete-yakaita kutadza pamusoro W = π×(3r2δ+3rδ2+δ3).
Mune fomula iri pamusoro, r ndiyo dhayamita yemukati memhete uye δ ndiyo hupamhi hwemhete.
Kutadza kumira pamberi penguva W = π×(3r2δ+3rδ2+δ3)
=π×(3×842×4+3×84×42+43) = 88768mm3
=88.768×10-6 m3
Kushungurudzika kunokonzerwa nemhepo inotakura ichiita pane yekukundikana pamusoro = M/W
= 1466/(88.768×10-6) =16.5×106pa =16.5 Mpa<<215Mpa
Pakati pavo, 215 Mpa isimba rekukotama reQ235 simbi.
Naizvozvo, hupamhi hweiyo weld seam yakagadzirwa uye yakasarudzwa nemugadziri wemwenje wezuva rezuva inosangana nezvinodiwa. Chero bedzi iyo welding quality inogona kuvimbiswa, kupikisa kwemhepo kwechigadziko chemwenje hakuna dambudziko.

Ruzivo rwechiedza chemugwagwa
Maawa ekushanda akakosha emagetsi ezuva emumugwagwa anokanganiswa nenzvimbo dzakasiyana dzekushanda dzakadai semamiriro ekunze uye nharaunda. Hupenyu hwesevhisi hweakawanda marambi emumugwagwa huchakanganiswa zvakanyanya. Pasi pekuongorora kwevashandi vedu vakakodzera, zvakaonekwa kuti kuchinja kwemagetsi emagetsi emugwagwa kune simba rakanaka uye kuchengetedza magetsi. Zviripachena, basa revashandi vekugadzirisa marambi emumugwagwa uye mwenje wepamusoro muguta redu rakaderedzwa zvakanyanya.
Fungidziro yesungano
Parizvino, magetsi ekumadhorobha emumigwagwa anonyanya kuve marambi esodium nemarambi emercury. Dunhu rekushanda rinoumbwa nemarambi esodium kana mercury bulbs, inductive ballasts, uye zvemagetsi zvinokonzeresa. Iyo simba chinhu 0.45 kana muripo capacitor isina kubatana uye iri 0.90. Kuitwa kwese kweiyo inductive load. Nheyo yekushanda yeiyi solar street light power saver ndeyekubatanidza yakakodzera AC reactor munhevedzano mumagetsi emagetsi. Kana iyo grid voltage yakaderera kupfuura 235V, reactor ipfupi-inotenderera uye haishande; kana magetsi egidhi akakwira kupfuura 235V, reactor inoiswa mukushanda kuti ive nechokwadi chekuti simba rekushanda remwenje wezuva rezuva haripfuuri 235V.
Dunhu rese rinoumbwa nezvikamu zvitatu: magetsi emagetsi, magetsi grid kuona uye kuenzanisa, uye inobuda actuator. Iyo yemagetsi schematic diagram inoratidzwa mumufananidzo uri pasi apa.
Iyo solar street landscape lighting power supply circuit inoumbwa nematransformer T1, diodes D1 kusvika D4, three-terminal regulator U1 (7812) nezvimwe zvinhu, uye zvinobuda +12V voltage kuti igone dunhu rekutonga.
Kuonekwa kwemagetsi gidhi remagetsi uye kuenzanisa kunoumbwa nezvinhu zvakaita se op-amp U3 (LM324) uye U2 (TL431). Iyo grid voltage inodzikiswa pasi neresistor R9, D5 iri hafu-wave yakagadziridzwa. C5 inosefetwa, uye DC voltage inosvika 7V inowanikwa sesampling yekuona voltage. Iyo sampled yekuona voltage inosefa neyakaderera-pass sefa inoumbwa neU3B (LM324) uye inotumirwa kumuenzanisi U3D (LM324) kuti ienzaniswe nereferensi voltage. Iyo referensi voltage yemuenzanisi inopihwa neiyo voltage referensi sosi U2 (TL431). Potentiometer VR1 inoshandiswa kugadzirisa amplitude yesampling yekuona voltage, uye VR2 inoshandiswa kugadzirisa referensi voltage.
Iyo inobuda actuator inoumbwa nerelays RL1 uye RL3, yakakwirira-ikozvino aviation contactor RL2, AC reactor L1 zvichingodaro. Kana iyo grid voltage yadzikira kupfuura 235V, muenzanisi U3D inoburitsa yakaderera, iyo matatu-chubhu Q1 yakadzimwa, iyo relay RL1 inoburitswa, iyo inowanzo kuvharwa yekubatana yakabatana nemagetsi emagetsi dhizaini RL2, RL2. inokwezvwa, uye reactor L1 ipfupi-inotenderera Haishande; kana iyo grid voltage yakakwira kupfuura 235V, muenzanisi weU3D inoburitsa yakakwira, iyo matatu-chubhu Q1 inobatidzwa, iyo relay RL1 inodhonzera mukati, iyo inowanzovharwa yekubata inobvisa dhizaini yemagetsi yeaviation contactor RL2, uye RL2 iri. kusunungurwa.
Reactor L1 yakabatana kune solar street light power supply circuit, uye yakanyanyisa high grid voltage chikamu chayo kuti ive nechokwadi chekuti simba rekushanda rechiedza chezuva remugwagwa haripfuuri 235V. Iyo LED1 inoshandiswa kuratidza kushanda kweiyo relay RL1. Iyo LED2 inoshandiswa kuratidza mamiriro ekushanda kweaviation contactor RL2, uye varistor MY1 inoshandiswa kudzima kuonana.
Basa reiyo relay RL3 ndere kudzikisa simba rekushandisa kweavhiyesheni contactor RL2, nekuti RL2 yekutanga coil kuramba ingori 4Ω, uye kupikisa kwecoil kunochengetwa panosvika 70Ω. Kana DC 24V yawedzerwa, iyo yekutanga ikozvino i6A, uye iyo yekugadziridza iripo zvakare yakakura kupfuura 300mA. Iyo relay RL3 inoshandura iyo avhiyesheni inobata RL2's coil voltage inoderedza kubata kwesimba kushandiswa.
Nheyo yacho ndeiyi: kana RL2 inotanga, iyo inowanzovharwa yekubatsira yekubatanidza shorts iyo coil ye relay RL3, RL3 inosunungurwa, uye iyo inowanzovharwa yekubatana inobatanidza high voltage terminal 28V ye transformer T1 kune bhiriji rectifier yeRL2; mushure mekunge RL2 yatanga, iyo Iyo inowanzovharwa yekubatsira yekubatanidza inovhurwa, uye relay RL3 inokwezvwa nemagetsi. Iyo inowanzo kuvhurika yekubata inobatanidza yakaderera voltage terminal 14V yetransformer T1 kune bhiriji rectification yekuisa terminal yeRL2 uye inochengetedza mutyairi wendege ne50% yekutanga coil voltage RL2 kudhonza-in state.
