Abstract
The utility model mainly relates to a water turbine water guide mechanism protecting device of 'a shear pin and a friction device'. The device is characterized by comprising a guide vane arm, a guide vane pin, a limiting block, a guide vane, the shear pin and a connecting plate, wherein the guide vane is fixed on the guide vane arm through the guide vane pin; the guide vane arm is connected with the connecting plate; the limiting block is arranged at one side of the guide vane arm; the shear pin is arranged at the joint of the guide vane arm and the connecting plate; and the friction device is arranged at one side of the shear pin. By adopting the structure of combining the shear pin and the friction device together, the friction device is increased on the basis of the traditional pure shear pin, the shear pin can still be used for shearing in use, the connecting plate is still connected together with the friction device through the guide vane arm, possible high stress is avoided by the relative slip between the connecting plate and the guide vane arm, a guide vane control mechanism can still control the guide vane through the friction pair, and the friction device provides an additional torque to prevent the guide vane from being out of control due to disordered swing under the action of hydraulic power.
Description
Technical field
The utility model relates to a kind of parts of water turbine, especially relates to the new type hydraulic turbine water distributor protective gear that a kind of employing " break pin and rubbing device " is combined.
Background technique
The purpose of water distributor protective gear is can not rotate because of foreign material in the current or other reason cause movable guide vane to be stuck in the hydraulic generator unit; This protective gear should break off to avoid producing heavily stressed other parts of destruction water distributor because of resistance is excessive this moment, and hydraulic generator unit out of control or whole is out of hand continuously to prevent to cause many stators simultaneously.Like Fig. 1; Fig. 2; Traditional water distributor protective gear comprises guide vane lever 11, stator pin 12, limiting stopper 15, stator 13, break pin 14, connecting plate 16, and stator 13 is fixed on the guide vane lever 11 through stator pin 12, and guide vane lever 11 is connected with connecting plate 16; Limiting stopper 15 is located at a side of guide vane lever 11, and break pin 14 is arranged on guide vane lever 11 and connecting plate 16 joints.It is to adopt the simple shear pin structure, though the slewing area of limiting stopper restriction stator is arranged, after break pin destroys; Guide vane lever and connecting plate are thrown off fully, cause stator to swing because of out of control, cause that waterpower is disorderly; Cause the disrumpent feelings continuously of many break pins, thereby make the whole generating unit out of hand.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical problem, and a kind of employing new type hydraulic turbine water distributor protective gear assembly that " break pin and rubbing device " combined is provided.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: the turbine gate mechanism protective gear of " break pin and rubbing device "; It is characterized in that: comprise guide vane lever, stator pin, limiting stopper, stator, break pin, connecting plate; Stator is fixed on the guide vane lever through the stator pin, and guide vane lever is connected with connecting plate, and limiting stopper is located at a side of guide vane lever; Break pin is arranged on guide vane lever and connecting plate joint, establishes rubbing device in a side of break pin.
The structure that it adopts break pin and rubbing device to combine; More traditional simple shear pin is many rubbing device, break pin still can be cut off during use, but this moment connecting plate and guide vane lever still connect together through rubbing device; There have slide relative to avoid between them to be possible heavily stressed; The stator control mechanism still can be through this friction pair control stator, and at this moment rubbing device is out of hand to prevent stator under hydraulic action, disorderly putting with regard to extra moment is provided
" break pin and rubbing device " structure has following three parts to constitute:
1. break pin
The main effect of break pin is following:
1). during the unit proper functioning, transmit the power control stator that the stator control mechanism transmits, make its proper functioning with the rubbing device acting in conjunction.
2). during the unit abnormal work, blocked inactively by foreign material in the current like stator, it will cut off other connected element of heavily stressed destruction to avoid producing.
2. rubbing device
By connecting plate, friction plate, guide vane lever, the rubbing device that pretension bolt is formed mainly acts on as follows:
1). during the unit proper functioning, transmit the power control stator that the stator control mechanism transmits, make its proper functioning with the break pin acting in conjunction.
2). during the unit abnormal work; Blocked by foreign material in the current like stator inactive, when break pin is cut off, the rubbing device slip of wanting to misplace; Other connected element of heavily stressed destruction of avoiding producing; Because of the pretightening force of pretension bolt exists always, just provide extra friction torque still to make control mechanism can control stator, do not make stator and whole unit out of hand.
3. instrument
In order monitoring whether the stator dislocation to be arranged, to be furnished with break pin and to cut off advertiser,, send the signalisation fault when between guide vane lever and the connecting plate relative movement being arranged when break pin is cut off.
Description of drawings:
Fig. 1 is existing break pin protective gear;
Fig. 2 is existing break pin protective gear plan view;
Fig. 3 is the utility model break pin protective gear structural representation;
Fig. 4 is the utility model break pin protective gear plan view.
Embodiment
Pass through embodiment below, and combine accompanying drawing 3, Fig. 4 does further bright specifically to the technological scheme of the utility model.
The turbine gate mechanism protective gear of " break pin and rubbing device "; It is characterized in that: comprise guide vane lever 1, stator pin 2, limiting stopper 3, stator 4, break pin 5, connecting plate 6; Stator 4 is fixed on the guide vane lever 1 through stator pin 2, and guide vane lever 1 is connected with connecting plate 6, and limiting stopper 3 is located at a side of guide vane lever 1; Break pin 5 is arranged on guide vane lever 1 and connecting plate 6 joints, establishes friction plate 7 in a side of break pin 5.Stator 4 links to each other with guide vane lever 1 through stator pin 2, and the size of these stator pins 2 depends on the moment of the maximum possible that needs transmission, but they are not to be disrumpent feelings element.Therefore, no matter under normal or the abnormal conditions, always guide vane lever 1 is fixed on the guide vane teunnion.Connecting plate 6 is clipped on the guide vane lever 1 by pretension bolt 9, between friction plate 7 is arranged, the pre-fastening moment of pretension bolt 9 is controlled by a torque spanner, the size of pre-fastening moment and friction factor have determined between connecting plate and the guide vane teunnion maximum moment that can transmit through friction.Also has a break pin 5 simultaneously between connecting plate and guide vane lever.Friction plate 7 and break pin 5 acting in conjunction carry-over moments.
The most probable position in stator 4 open and close orientation can be limited by the limiting stopper on the top cover 3, and it will stop the big shearing of crossing of guide vane lever 1 to move.Because the existence of friction plate 7, the motion of stator 4 always under the control of servomotor, have solved the runaway condition that the simple shear pin is cut 5 stators 4 when disconnected.
As long as unclamp pretension bolt 9, just can easily stator be adjusted or reset, forward stator 4 to correct position, load onto new break pin, tighten pretension bolt 9 with torque spanner.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the utility model is not limited to the foregoing description, and many distortion can also be arranged.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all should think the protection domain that belongs to the utility model.
