Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of supreme weight accumulation of energy lock ingot formula jet deflector of lifting phenomenon of jet deflector behind the jet of cutting is provided.
The purpose of this utility model can be reached by following technical proposals: (a) weight accumulation of energy lock ingot formula jet deflector, and comprise connecting rod base, connecting rod, jet deflector axle and be installed in jet deflector on the jet deflector axle, it is characterized in that having pin-and-hole on (i) connecting rod; Locating stud inserts in the pin-and-hole; Pull bar passes successively to adjust in the cavity that is inserted in the locking seat behind nut, the stage clip and is threaded with locating stud, adjusts nut by screwing in the locking cavity mouth; (ii) weight is enclosed within on the jet deflector axle by flat key and fixes with Cock screw.
(b) the described weight accumulation of energy lock of a ingot formula jet deflector is characterized in that also having a supporting plate; Supporting plate one end respectively with connecting rod base, lock spindle support mechanical fixation, the other end is enclosed within on the jet deflector axle and fixes by fastening piece with the water turbine chassis block.
The utility model has following advantage compared to existing technology:
1, the locating stud landing is in the pin-and-hole of connecting rod, and gravitational potential energy that weight holds prevented all effectively after discharging jet deflector on lift bounce-back, thereby reliability increases substantially, and reached dual fail-safe.Simultaneously, weight is in energy accumulating state, has improved the sensitivity of mechanical motion such as connecting rod in the jet deflector incision water flow process.
2, be provided with supporting plate, integral processing is good, and is with low cost, easy to maintenance, and can be applied to reliably in the unit transformation of old power station.
3, can with the interlock of the speed limit circuit of water turbine, realize control automatically, cut-out pressure water jet reliably has a power failure or the automatic control circuit fault if meet rapidly, can manually move handle, closes jet deflector rapidly, reliable cut-out pressure water jet.

Embodiment
The utility model is further described below in conjunction with accompanying drawing.Weight accumulation of energy lock ingot formula jet deflector, it comprises connecting rod base (8), connecting rod (14), jet deflector axle (22), and is installed in the jet deflector (20) on the jet deflector axle (22).The utility model has pin-and-hole on connecting rod (14); Locating stud (13) inserts in the pin-and-hole; Pull bar (9) passes successively to adjust in the cavity that is inserted in locking seat (12) behind nut (10), the stage clip (11) and is threaded with locating stud (13), adjusts nut (10) by screwing in locking (12) cavity mouth.Weight (21) is enclosed within jet deflector axle (22) by flat key and upward fixes with Cock screw.Here, stage clip (11) two ends are against respectively to be adjusted on nut (10) and the locating stud (13), thereby the screw-in scale of adjustment nut (10) shows that locating stud acts on the amount of force in the pin-and-hole.
In order to strengthen integral processing, of the present utility modelly can increase supporting plate (15).Supporting plate (15) one ends respectively with connecting rod base (8), lock spindle support (12) mechanical fixation, the other end is enclosed within that jet deflector axle (22) is gone up and water turbine chassis block (23) is fixed by fastening piece.Mechanical fixation can be fixed by fastening piece, also can weld fixing.
Operating process of the present utility model is: when the rotating speed of water turbine rose to setting value, speed limit circuit triggers electromagnet (3) promotes connecting lever (6) rotation threaded off suspension hook (5).Under the promotion of the elastic force of spring (2) and the accumulation of energy of weight (21) institute, connecting rod (14) travels forward along the determined direction of connecting rod base (8), and then drives pivoted arm (19) rotation.Drive jet deflector (20) by jet deflector axle (22) simultaneously and rotate to position, water turbine jet-core region, the press water jet is folded to leaves blade, the cut-out pressure water jet.In the process, weight (21) rotates next angle by former level position at this moment, and locating stud (13) falls in the pin-and-hole of connecting rod after connecting rod (14) is gone up slip automatically simultaneously, realizes lock state.
Locating stud that is in the lock state (13) and weight (21) can prevent effectively that all the jet deflector under the lock state from upwards lifting because of the influence that is subjected to jet impact force.Therefore this " double insurance " structure has improved the reliability of jet deflector greatly, takes place when very having avoided the unexpected removal of load of unit effectively that rotating speed rises and the excessive power station accident that causes of water hammer pressure rising.
During unlatching, mentioning pull bar (9) extracts locating stud (13) in connecting rod (14) pin-and-hole, pull handle (7) backward and promote that backing pin (26) moves and then pressure spring (2) connecting rod (14) backward on the connecting rod, allow weight (21) be in horizontal accumulation of energy position, again suspension hook (5) is hooked on the connecting rod base (8).At this moment, jet deflector is in opening state, is in vertical position, and jet just can pass through in jet deflector, and unit just can have been started shooting.
The utility model is compared existing jet deflector on China's old power station unit, only many supporting plate, the installation of locating stud, the uses of heavy bell, thereby the repacking upgrading of old power station is easy, social benefit is good.
