This drilling adopts crank connecting link and walking beam percussion mechanism, which make the drilling possess two percussive functions, normal drilling takes connecting link impact as main mode, when encountering special situation and the connecting link impact can not drill, it can transform into hoisting impact, the stroke length can be modulated, it realizes automatic percussive drilling due to continuous operating of connecting link percussive mechanism, these can enhance drilling efficiency and relieve labor intensity ; it adopts pumping reverse circulation to drain slag, which not only resolves the drilling difficulty in special stratum such as pebble and gravel stratum and hard stratum, but also resolves the problem that the percussive drill ' s efficiency is low ; it adopts spur gear differential mechanism as double cylinders lazy tongs of main hoist, which not only ensures the balance state of drilling tool, but also reduces the mechanical design, and reduces the cost ; the bottom plate traveling motion of this drilling machine adopts walking type ; the drilling tower adopts hydraulic pressure uprising, and reduces the assistant operating time
該鉆機採用曲柄連桿、游梁式沖擊機構，使鉆機具有兩種沖擊功能;正常鉆進以連桿沖擊為主，遇到特殊情況，用連桿沖擊不能鉆進時，可轉為卷揚沖擊，沖程可調，因連桿沖擊機構連續工作，所以實現了自動沖擊鉆進，可提高鉆進效率，減輕勞動強度;採用泵吸反循環的方式排渣，既能有效解決卵礫石地層、堅硬地層等特殊地層鉆進的困難，又很好地解決了沖擊鉆機效率低下的問題;採用直齒圓柱齒輪差速機構作為主卷揚的雙筒同步機構，既保證了鉆具處于平衡狀態，又大大簡化了該機構設計，降低了成本;該鉆機底盤行走移位採用步履式;鉆塔採用液壓起立，減少了輔助作業時間。 -

In this thesis, by the summarizing and analyzing about the present stability control study state of synchronous generator unit, it is achieved that the governor pss ( gpss ) is more suitable for the stability control of multi - machine system because of its better decoupled character than conventional pss ; the intelligence control theory is more reasonable than conventional methods to design the hydro - generator unit gpss because of the uncertainty of mathematical model of hydro - electricity system caused by intense nonlinear character and time - variant operating mode of hydro - turbine and water - hammer effect of hydraulic system
本文對同步發電機組穩定控制的研究現狀進行了綜述和分析。認為：與常規pss相比，調速器側pss （ gpss ）具有良好的解耦特性，更宜用於多機系統的穩定控制；由於水輪機特性的強非線性、工況的時變性以及引水系統的水擊效應所導致的水電系統數學模型的不確定性，採用智能控制理論設計水電機組gpss較常規設計方法更為合理。 -
Hongjiadu hydraulic power plant is the only leading water storage reservoir of wujiang cascade hydraulic stations, which is a full - time storage reservoir. 2 * landslide body is distributed at the right side of downstream, which is just located in the region of energy dissipation. erosion gully may cut the bottom of the landslide body. there are roads on the top of the landslide body during the construction period and operating period
洪家渡水電站是烏江梯級水電站中唯一具有多年調節性能的「龍頭」水庫， 2 #塌滑體分佈於壩址下游右岸，恰好位於泄洪消能防沖區內，沖坑將塌滑體下部切腳，而且施工期和運行期在其上都布置有公路，因此2 #塌滑體失穩將影響整個水電站的正常運行。 -
