Abstract
A kind of guide vanes of water turbine operating device, comprise guide vane lever, secondary guide vane lever, adjusting nut, secondary guide vane lever quantity is identical with stator number, and secondary guide vane lever is fixed on guide vane lever by break pin, and wherein the end of driving pair guide vane lever is connected with servomotor; The both sides ear handle pin of secondary guide vane lever is fixed with left ear handle and auris dextra handle respectively, and the left ear handle between adjacent pair guide vane lever, auris dextra handle are connected by adjusting nut.Guide vanes of water turbine operating device of the present utility model, guide vane servomotor promotes or pulls driving pair guide vane lever, driven secondary guide vane lever, synchronous unlatching, closing motion are carried out to stator, the state of stator can be regulated well, make the opening value that formed between stator identical, thus enter runner with ensureing the uniform flow of unit, make stable operation of unit, adopt secondary guide vane lever to replace control ring simultaneously, greatly reduce the cost of production of mechanism.
Description
Technical field
The utility model relates to hydraulic turbine power generation, especially a kind of guide vanes of water turbine operating device.
Background technique
Existing guide vanes of water turbine operating device be all drive connecting plate by control ring, guide vane lever is opened stator, closing motion.Control ring is that a fabricating cost is high, the parts that processing request is also higher, and because manufacturing tolerance can cause, the opening value between stator is not of uniform size to be caused, and makes the flow of aperture everywhere different, thus affects the stability of unit.
Summary of the invention
It is low that the purpose of this utility model is just to provide a kind of cost of production, can realize the guide vanes of water turbine operating device that aperture between each stator is identical.
Guide vanes of water turbine operating device of the present utility model, comprise guide vane lever, guide vane teunnion, secondary guide vane lever, left ear handle, auris dextra handle, adjusting nut, it is characterized in that, secondary guide vane lever is divided into driving pair guide vane lever and driven secondary guide vane lever, for even circumferential arrangement, secondary guide vane lever quantity is identical with stator number, and secondary guide vane lever is fixed on guide vane lever by break pin, wherein driving pair guide vane lever quantity is one, and the end of driving pair guide vane lever is connected with servomotor; The both sides ear handle pin of secondary guide vane lever is fixed with left ear handle and auris dextra handle respectively, and the left ear handle between adjacent pair guide vane lever, auris dextra handle are connected by adjusting nut, and the side of adjusting nut is dextrorotation internal thread, and opposite side is levogyrate inner thread.
Guide vanes of water turbine operating device of the present utility model, guide vane servomotor is connected with driving pair guide vane lever by pin, and the both sides of driving pair guide vane lever are connected with left and right ear handle by ear handle pin; Left and right ear handle is connected with another set of ear handle, driven secondary guide vane lever by adjusting nut again, and same case connects, and is in the end connected without the need to ear handle and adjusting nut between the secondary guide vane lever of two pieces, thus forms a set of gate operating mechanism.Guide vane servomotor promotes or pulls driving pair guide vane lever, driving pair guide vane lever is promoted by ear handle, adjusting nut or pulls next group driven secondary guide vane lever, ear handle and adjusting nut, and driven secondary guide vane lever and guide vane lever are connected by break pin, synchronous unlatching, closing motion are carried out to stator.Because adjusting nut contains left and right screw thread, the state of stator can be regulated well, make the opening value that formed between stator identical, thus enter runner with ensureing the uniform flow of unit, make stable operation of unit, ensure that the object reliably controlling unit output, adopt secondary guide vane lever to replace control ring simultaneously, greatly reduce the cost of production of mechanism.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of guide vanes of water turbine operating device, comprise guide vane lever 8, guide vane teunnion 9, secondary guide vane lever, left ear handle 5, auris dextra handle 7, adjusting nut 6, it is characterized in that, secondary guide vane lever is divided into driving pair guide vane lever 1 and driven secondary guide vane lever 4, for even circumferential arrangement, secondary guide vane lever quantity is identical with stator number, and secondary guide vane lever is fixed on guide vane lever 8 by break pin 2, wherein driving pair guide vane lever 1 quantity is one, and the end of driving pair guide vane lever 1 is connected with servomotor 10; The both sides ear handle pin 3 of secondary guide vane lever is fixed with left ear handle 5 and auris dextra handle 7 respectively, and the left ear handle 5 between adjacent pair guide vane lever, auris dextra handle 7 are connected by adjusting nut 6, and the side of adjusting nut 6 is dextrorotation internal threads, and opposite side is levogyrate inner thread.
