Abstract
The invention provides a V-shaped safety connecting-rod mechanism for a water guiding mechanism of a through-flow turbine. The V-shaped safety connecting-rod mechanism for the water guiding mechanism of the through-flow turbine is composed of a V-shaped safety connecting rod, bearing pressing plates, bolts, ball bearings, eccentric pins, bolts, spring washers, a detection plate, a limit switch, screws, connecting pins and check rings. When a guide vane gets stuck due to foreign matter in the closing process, the V-shaped safety connecting rod can be bent and broken when servomotor operating force borne by the V-shaped safety connecting rod reaches a certain threshold value, other guide vanes continue to be closed normally under the effect of the servomotor operating force, and thus the effects of protecting the water guiding mechanism is achieved; and the V-shaped safety connecting-rod mechanism is simple and reliable in structure, convenient to maintain, low in manufacturing cost, and suitable for water guiding mechanisms of small-size and medium-size through-flow turbines.
Description
Technical field：
The present invention relates to a kind of guide mechanism in flow-through turbine V-type safe connecting rod mechanism.
Background technology：
Guide mechanism in flow-through turbine generally adopts spring safety link mechanism at present, and this mechanism action is reliable, but knot
Structure is complicated, relatively costly it is adaptable to Large Type Bulb Turbine.V-type safe connecting rod mechanism is then more suitable for middle-size and small-size tubular
The hydraulic turbine, when being blocked by foreign matter in stator closing process, corresponding V-type safe connecting rod fractures, and does not affect remaining stator
Normal switching-off, after changing V-type safe connecting rod, unit just can normally run.V-type safe connecting rod structure is simple, easy to maintenance.Due to
It is small probability event that stator is blocked by foreign matter when closing, and compares spring link for middle-size and small-size tubular turbine V-type safe connecting rod
Also more economical.
Content of the invention：
It is an object of the invention to provide a kind of structure simple, convenient and practical, reliable guide mechanism in flow-through turbine peace
Full linkage.Technical scheme is：By V-type safe connecting rod (1), bearing plate (2), bolt (3), ball bearing (4), cam pin
(5), bolt (6), spring washer (7), detection plate (8), limit switch (9), screw (10), link pin (11), back-up ring (12) group
Become；V-type safe connecting rod (1) two ends arrange ball bearing (4) bore, and middle part has v-notch, and v-notch angle is 100 °, when leading
When being blocked by foreign matter in leaf closing process, connecting rod can fracture in the presence of servomotor operating physical force at v-notch；Bearing plate
(2) have bolt hole on, be fixed on V-type safe connecting rod (1) using bolt (3), bearing plate (2) is used for compressing ball bearing
(4)；Cam pin (5), link pin (11) are utilized respectively back-up ring (12) and are assembled with ball bearing (4), and ball bearing (4) is arranged on V-type peace
In full connecting rod (1) bore；Detection plate (8) passes through bolt (6) and spring washer (7) is fixed on V-type safe connecting rod (1) side；Limit
Bit switch (9) is fixed on V-type safe connecting rod (1) by screw (10), the action contact of limit switch (9) and detection plate (8)
Contact, once V-type safe connecting rod (1) bends, limit switch (9) sends actuating signal.
Technique effect：
V-type safe connecting rod mechanism passes through the accurate width dimensions calculating at v-notch and ensures transmission during connecting rod normal work
Servomotor operating physical force (pulling force or pressure)；When being blocked by foreign matter in stator closing process, corresponding V-type safe connecting rod bears
Operating physical force reaches a threshold value and bending damage can occur, and closes resistance and greatly reduces, remaining stator then can be in the effect of operating physical force
Lower normal switching-off；After changing V-type safe connecting rod, unit just can normally run.
The invention has the advantages that：
1) dependable performance.Servomotor operating physical force is transmitted, the operating physical force bearing when stator blocks arrives during connecting rod normal work
Reach a threshold value connecting rod to bend, but remaining stator all can normal switching-off；
2) structure is simple, low cost of manufacture；
3) change connecting rod take short, easy to maintenance；
Brief description：
Fig. 1 is V-type safe connecting rod structure normal operating conditions front view
Fig. 2 is V-type safe connecting rod structure normal operating conditions top view
Fig. 3 is V-type safe connecting rod textural anomaly guard mode schematic diagram
Specific embodiment：
The present invention is a kind of guide mechanism in flow-through turbine V-type safe connecting rod mechanism, and critical piece assembly relation is shown in Fig. 1
Shown：Cam pin 5, link pin 11 are utilized respectively back-up ring 12 and are assembled with ball bearing 4, two pieces ball bearing 4 is separately mounted to V-type
In safe connecting rod 1 bore；Bearing plate 2 is fixed on V-type safe connecting rod 1 using bolt 3, for compressing ball bearing 4；Detection plate
8 are fixed on V-type safe connecting rod 1 side by bolt 6 and spring washer 7；Limit switch 9 is fixed on V-type safety by screw 10
On connecting rod 1；The action contact of limit switch 9 is contacted with detection plate 8.
Servomotor operating physical force is transmitted, that bears when stator blocks connects during described V-type safe connecting rod mechanism's normal work
Power device operating physical force reaches a threshold value V-type safe connecting rod and bends, but remaining stator all energy normal switching-offs, play protection water guide
The effect of mechanism.
