Abstract
The invention relates to a transmission mechanism of a hydroturbine water guide part sleeve, comprising guide vane arms arranged on a guide vane, and a control ring connected with a hydraulic servomotor. The invention is characterized in that a connecting plate for acquiring bending signals is arranged between the guide vane arms and the control ring, one end of the connecting plate is connected with the guide vane arms by a connecting rod pin and a bearing, the other end of the connecting plate is connected with the control ring by the connecting rod pin and the bearing, and the connecting plate is provided with a signal collector which is connected with a warning device. In the invention, an existing snap pin is not needed, all the guide vane arms are the same, the structure is simplified, and manufacturing and installation are both relatively easy. When the guide vane is stuck by a foreign body and can not be closed normally, force on the hydraulic servomotor is transferred to the connecting plate by the control ring; when the force exerted on the connecting plate exceeds the limit the connecting plate can bear, the connecting plate is bent, the signal collector sends out an alarm signals, the machine set is powered off and the connecting plate is replaced; and in addition, the connecting plate is easier in manufacturing and lower in manufacturing cost as compared with the snap pin.
Description
Technical field
The present invention relates to and belongs to hydraulic turbine generator manufacturing technology field, the driving mechanism of particularly a kind of water turbine water guide sector cover.
Background technique
The driving mechanism of water turbine water guide sector cover generally adopts the ear handle transmission, this structure includes ear handle, rotation set, link pin, breaks compositions such as pin, when the unit normal switch, power on the servomotor passes to ear handle mechanism by control ring, ear handle links to each other by link pin with guide vane lever, and power is handled the switch of stator by guide vane lever.When stator is blocked by foreign matter normally to close, power passes to ear handle mechanism by control ring on the servomotor, pass to connecting plate by link pin again, connecting plate links to each other by breaking pin with guide vane lever, and this moment, to break pin stressed, when the stressed operating limit above it of institute, breaking pin is broken, this is that telltale sends alarm signal, and the unit shutdown is changed and broken pin.This kind ear handle driving mechanism is owing to adopt screw-thread fit to screw between ear handle and the rotation set, both sides are respectively left-handed and dextrorotation, when unit is worked, because the vibration of unit, be easy to generate the phenomenon that releases between rotation set and the ear handle, cause coming off of ear handle,, can produce very serious consequence if can not in time find.The ear handle driving mechanism as shown in Figure 3 and Figure 4.
Summary of the invention
The present invention for solve the technical problem that exists in the known technology provide a kind of simple in structure, easy to maintenance, saved and made and the driving mechanism of the water turbine water guide sector cover of installation time.
The technological scheme that the present invention takes for the technical problem that exists in the solution known technology is:
The driving mechanism of a kind of water turbine water guide sector cover, comprise the guide vane lever that is installed on the stator, the control ring that is connected with servomotor, it is characterized in that: be provided with the connecting plate of gathering the bending signal between described guide vane lever and the control ring, one end of connecting plate is connected with guide vane lever with bearing by link pin, the other end of connecting plate is connected with control ring with bearing by link pin, and described connecting plate is provided with signal picker, and signal picker connects warning device.
The present invention can also adopt following technological scheme:
Described connecting plate comprises the joint at two ends and the V-notch of easy bending, and the end of V-notch is provided with the anti-circular arc of tearing.
The outside of described eccentric link pin is equipped with gland by fastening piece.
Described link pin is the eccentric link pin.
Advantage and good effect that the present invention has are: the transmission part of water distributor is a vitals in the water wheels unit, not only will consider its easy accessibility, also has the safety problem in the using process.This kind bending link configuration has at first been simplified the transmission process of unit from structure, about two ear handles and rotation set replace with connecting plate, just can not produce because unit vibration makes the phenomenon that driving mechanism is loosening.This structure has been cancelled and has been broken pin, owing to adopt when breaking pin structure, breaking pin is to place at interval, so just caused guide vane lever must adopt two kinds of structures, a kind of pin of breaking, another kind are the structures of not breaking pin, the bending link configuration does not then have these misgivings, all guide vane levers all are identical, designs simplification, and making and installation are all fairly simple.When stator is blocked by foreign matter normally to close, power on the servomotor passes on the connecting plate by control ring, connecting plate is stressed, when stressed greater than connecting plate bear the limit time, connecting plate generation bending, this moment signal picker send alarm signal, the unit shutdown, change connecting plate, and the making of connecting plate ratio to break pin simple, make lower than breaking the pin cost.

Embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1 and Fig. 2, the driving mechanism of a kind of water turbine water guide sector cover, comprise the guide vane lever 3 that is installed on the stator 1, adopt between guide vane lever 3 and the stator 1 and divide half bond 2 to be fastenedly connected, control ring 8 is connected with servomotor, be provided with the connecting plate 7 of gathering the bending signal between described guide vane lever 3 and the control ring 8, when the characteristics of this connecting plate are to be subjected to bearing the limit, bending can take place send signal, its main structure is: described connecting plate 7 comprises the joint 7-1 at two ends and the V-notch 7-2 of easy bending, and the end of V-notch 7-2 is provided with the anti-circular arc 7-3 that tears.One end of connecting plate 7 is connected with guide vane lever 3 with bearing 4 by link pin 6; for guaranteeing transmission accurately; link pin in this structure adopts the eccentric link pin, and the outside of described eccentric link pin is equipped with gland 5 by fastening piece, and this gland plays the effect of protection bearing.The other end of connecting plate is connected with control ring 8 with bearing 4 by link pin 6, and this link pin adopts same eccentric link pin, and by fastening piece gland is installed in the outside of eccentric link pin.Described connecting plate 7 is provided with signal picker 9, and signal picker 9 connects the warning device (not shown).
