Description
Technical field
It the utility model is related to hydroenergy storage station guide vane servomotor auxiliary accessories technical field, and in particular to one kind is drawn water
Storage station's guide vane servomotor lower connecting plate anti-drop device.
Background technology
Precious spring hydroenergy storage station installs 4 300MW reversible pump turbine-generator units, passes through 20 single stator relays
It is electric energy that device, which controls current driving runner to rotate the potential energy of water, and water distributor is the core component in power station, speed regulator
Electric part, which is issued an order, makes guide vane servomotor open and close, and servomotor drives connecting lever to rotate by upper and lower two pieces of connecting plates, and connecting lever leads to
Cross three tapered dowel driving stator open and close.But during unit day-to-day operation, it is found that lower connecting plate easily takes off
Fall, only a connecting plate, switch stator has potential safety hazard.
Utility model content
The utility model redesigns to the screw rod of original fixed lower connecting plate, forms a kind of water-storage stator and connects
Power device lower connecting plate anti-drop device.
The technical scheme of use：A kind of hydroenergy storage station guide vane servomotor lower connecting plate anti-drop device, including screw rod
And cap head is contained in nut, one end of the screw rod, the other end is provided with thin diameter section, and the end set of thin diameter section has prong, is located at
Rotation strip is provided with by rotating shaft in prong, sliding sleeve, sliding sleeve and thin diameter section root are set with close to root position in the thin diameter section
Thrust spring is connected between portion.
Block machine is provided with the outside of the end of the prong, the external diameter of block machine is more than thin diameter section external diameter and no more than outside screw rod
Footpath.Supporting sleeve is housed in the screw rod outer sheath.
The beneficial effects of the utility model：The utility model increases spiro rod length on the basis of original single bolt,
Intensity is changed to 12.9 grade high-strengths, and using two nuts, nut fastens in prepackage, ensure that lower connecting plate and upper junction plate
Designed distance, nut mutually fasten with nut, prevent the loosening of nut in downward direction, and pin bolt is prevented as the second pipe protection
Only connecting plate comes off, and can be good as a reference point of current check, the covering device ingehious design, practical application effect.
Brief description of the drawings
Fig. 1 is installment state schematic diagram of the present utility model.
Fig. 2 is the structural representation of anti-drop device in Fig. 1.
Label in figure：1 is upper junction plate, and 2 be lower connecting plate, and 3 be tilting member one, and 4 be tilting member two, and 5 be anticreep
Dropping control device, 51 be screw rod, and 52 be nut, and 53 be thin diameter section, and 54 be prong, and 55 be rotation strip, and 56 be rotating shaft, and 57 be sliding sleeve, 58

Embodiment
Embodiment 1：The anti-drop device of hydroenergy storage station guide vane servomotor lower connecting plate 2, for installed in as shown in Figure 1
Upper connection sheet and lower connection sheet between.The device includes screw rod 51 and nut 52 as described in Figure 2.Wherein, one end of screw rod 51
Containing cap head, the other end is provided with thin diameter section 53, and the end set of thin diameter section 53 has prong 54, passes through rotating shaft in prong 54
56 are provided with rotation strip 55.Angle by stirring the rotation strip 55 disclosure satisfy that installation nut 52 or stop the work of nut 52
With.
In addition, in order to reach the purpose fixed to rotation strip 55, cunning can be set with close to root position in thin diameter section 53
Set 57, thrust spring 58 is connected between sliding sleeve 57 and the root of thin diameter section 53.Stirring sliding sleeve 57 backward can discharge to rotation strip
55 effect of contraction, the structure make the rotation of rotation strip 55 and positioning become very convenient.
Block machine can also be provided with the outside of the end of prong, the external diameter of block machine is more than the external diameter of thin diameter section 53 and is not more than spiral shell
The external diameter of bar 51.So as to block machine can anti-anti-skid sheath come off.
Alternatively, it is also possible to be equipped with supporting sleeve 6 in the outer sheath of screw rod 51, as shown in figure 1, by collar supports in upper junction plate
Between 1 and lower connecting plate 2, in order to which screw rod 51 successfully can be drawn in the hole between upper junction plate 1 and lower connecting plate 2,
When turn-knob nut 52 is upper junction plate 1 and lower connecting plate 2 inwardly furthers, sleeve pipe has internal support effect again.
