本研究旨在研發適用於大管徑的管流發電機。其特色,係配合管道不停輸開孔封堵技術,即可快速與簡易的安裝永續供電檢測系統。本文主要報告研發過程中的兩種設計: 軟軸設計:係採用軟軸取代硬軸與齒輪,以減少齒輪機件之間的磨損與能量損耗;再搭配磁耦合一體式設計,進而改善組裝的手續、體積縮小與往後漏水的疑慮;軟軸設計因軟軸與套管摩擦太大,導致負載一加入,葉輪便無法繼續運轉,以致無法達到發電的基本條件。 短硬軸設計:係結合軟軸設計與傳統軸傳的優點,採用單一軸為傳導媒介,更將發電系統整體移入管道內部,增加系統整合程度,提高可靠性;短硬軸設計經過葉片的交叉比對與後續鐵環的加入,電壓從0.46V提升至0.72V,雙葉輪的配置與鐵環的加入,有助於提升發電量與系統的穩定性。
This study aims to research and development for large diameter pipe flow generator. Its characteristics, with the Tunnel opening and sealing technology, it is a quickly and easy installation of sustainable power detection system. This paper reports two kinds of design development process: Flexible shaft Design: Flexible shaft is used to replace the hard shaft and gears, mechanical gears to reduce wear and energy loss between; and then with magnetic coupling one design, thereby improving the procedures for assembly, the volume reduced and the subsequent leakage concerns; shaft design for Too much friction with the shaft casing, causing the load of a join, the impeller can not continue to operate, so that power can’t achieve the basic conditions. Short-hard shaft design: Is a combination of flexible shaft of transmission design and the traditional advantages of using a single axis Chuandao media, but will power the whole system into the internal channels to increase system integration, increase reliability; after a short shaft design leaves the hard cross-matching and follow-up of iron Central to join, upgrade to the voltage from 0.46V 0.72V, dual impeller configuration and hoop to join, help to improve the generation and system stability.
