Because of the virtue of automatically switching , simple structure and low cost , etc , the hydraulic automatic tilting gates with connecting lever and rolling wheel have been wildly applied in all kinds of water conservancy and brought much economic benefit 連桿滾輪式水力自動(dòng)翻板閘門(mén)因其能隨水位漲落而自動(dòng)啟閉,結(jié)構(gòu)簡(jiǎn)單、造價(jià)低廉,等優(yōu)點(diǎn),在各類(lèi)水利工程中得到廣泛應(yīng)用,并產(chǎn)生了很好的經(jīng)濟(jì)效益。
The main contents in the paper are as follows : ( 1 ) the operational principle of the hydraulic automatic tilting gates with connecting lever and rolling wheel were analyzed . using block diagram , the author elaborated on the running course and steady factors of the tilting gate . then the instantaneous running center in the running course of the tilting gate was brought forward , and the trochoid of the center was described 本文研究的主要內(nèi)容如下: ( 1 )分析闡述了水力自動(dòng)翻板閘門(mén)的工作原理和運(yùn)轉(zhuǎn)機(jī)理,結(jié)合框圖詳細(xì)分析說(shuō)明了翻板閘門(mén)的運(yùn)轉(zhuǎn)過(guò)程及其穩(wěn)定條件,給出了閘門(mén)在運(yùn)行過(guò)程中的瞬心軌跡線,分析研究了閘門(mén)運(yùn)動(dòng)過(guò)程中的基本平衡方程。
According to the analysis of the gate , the author put forward a mathematical model of the optimization design of the hydraulic automatic tilting gate , and then worked out the structural stability optimization design program of the hydraulic automatic tilting gate . then by the calculation of the program , a better design for a certain project was gained 根據(jù)對(duì)翻板閘門(mén)的運(yùn)行分析,提出了翻板閘門(mén)優(yōu)化設(shè)計(jì)數(shù)學(xué)模型的一般表達(dá)式,并據(jù)此編制出水力自動(dòng)翻板閘門(mén)的結(jié)構(gòu)穩(wěn)定性?xún)?yōu)化設(shè)計(jì)程序,對(duì)某一工程實(shí)例,通過(guò)程序的計(jì)算,得到了較理想的設(shè)計(jì)成果。
( 4 ) the running state and hydraulic property of the hydraulic automatic tilting gate with connecting lever and rolling wheel were analyzed . the open - door curve , start - up water level and shutdown water level were ascertained , then the influence of lower reaches of a river to the running of a tilting gate was analyzed ( 4 )析闡述了連桿滾輪式水力自動(dòng)翻板閘門(mén)的工作狀態(tài)與水力特性,推求了閘門(mén)的開(kāi)門(mén)曲線、啟門(mén)水位和回關(guān)水位,并分析了下游水位對(duì)翻板閘門(mén)運(yùn)行的影響。
The stability analysis and structural optimization design of the hydraulic automatic tilting gates with connecting lever and rolling wheel were carried out in the paper to make them not only be better applied in all kinds of water conservancy but also be wildly applied in ship project , city environmental protection , and other correlative project , further to better the social and living condition 本文對(duì)連桿滾輪式水力自動(dòng)翻板閘門(mén)進(jìn)行穩(wěn)定性分析和結(jié)構(gòu)優(yōu)化設(shè)計(jì),使得它們不僅能更好地應(yīng)用于各類(lèi)水利水電工程中,而且能廣泛應(yīng)用于航運(yùn)工程、城市環(huán)境保護(hù)和其他相關(guān)工程中,將會(huì)對(duì)社會(huì)的發(fā)展和生活環(huán)境的改善有著重要的意義。
