Abstract
The utility model relates to a guide vane drive mechanism of a mixed flow type water turbine and an axial flow type water turbine, which is characterized in that the drive mechanism comprises a guide vane control ring and two servomotors, wherein the guide vane control ring is connected with the two servomotors by large lug holes at two sides; and the large lug holes of the guide vane control ring is provided with a totally-closed position, a middle travel position and a totally-opened position. The guide vane drive mechanism is characterized in that the servomotors are positioned between the totally-closed position and the middle travel position of the large lug holes of the guide vane control ring. The servomotors are arranged between the totally-closed position and the middle travel position of the large lug holes of the guide vane control ring, thus reducing the swing angle of push/pull rods of the servomotors, reducing additional stress on the push/pull rods of the servomotors, leading the servomotors to move more steadily, leading to more reasonable stressed status, effectively reducing abrasion of the push/pull rods of the servomotors, prolonging the service life of the servomotors and leading to safe and reliable work.
Description
Technical field
The utility model relates to a kind of guide vanes of water turbine driving mechanism, particularly a kind of mixed-flow and axial flow hydraulic turbine gate linkage.
Background technique
Servomotor is the power unit in the gate linkage, and the aperture of stator is regulated and realized that by stretching of servomotor pull bar it is handled by the rotation of control ring, the swing of linkage mechanism exactly.General every water turbine is joined two servomotors 2, is arranged in the homonymy of unit, as shown in Figure 1.The spacing of two servomotors 2 is general identical with the spacing Ф of the big earhole of control ring.The servomotor pull bar except a flexible motion is arranged, also has the swing with the big ear of control ring in total travel under piston action like this, sees θ angle among Fig. 2.If the big ear stroke of control ring is big more, then this pivot angle θ is just big more, not so good to the stress of servomotor pull bar like this, straight-cylinder servomotor especially, use a period of time after, pull bar weares and teares easily.
Summary of the invention
The utility model provides a kind of mixed-flow and axial flow hydraulic turbine gate linkage that can alleviate the wearing and tearing of servomotor pull bar for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of mixed-flow and axial flow hydraulic turbine gate linkage, comprise regulating ring of wicket gate and two servomotors that are connected by the big earhole in its both sides with described regulating ring of wicket gate, the big earhole of described regulating ring of wicket gate has complete shut-down position, middle of stroke position and fully open position, and described servomotor is between the complete shut-down position and middle of stroke position of the big earhole of described regulating ring of wicket gate.
Advantage and the good effect that the utlity model has are: between the complete shut-down position and middle of stroke position that servomotor are arranged in the big earhole of regulating ring of wicket gate, reduced the pivot angle of servomotor pull bar, servomotor pull bar additional stress is reduced, make its motion more steady, stress is more reasonable, alleviate the wearing and tearing of servomotor pull bar effectively, prolonged the working life of servomotor, safe and reliable.
Description of drawings
Fig. 1 is the utility model prior art constructions schematic representation;
Fig. 2 is the schematic diagram of Fig. 1;
Fig. 3 is a structural representation of the present utility model;
Fig. 4 is the schematic diagram of Fig. 3.
Among the figure: 1, regulating ring of wicket gate, 1-1, the big earhole of regulating ring of wicket gate, 2, servomotor, the complete shut-down position of A, the big earhole of regulating ring of wicket gate, the middle of stroke position of B, the big earhole of regulating ring of wicket gate, the fully open position of C, the big earhole of regulating ring of wicket gate.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 3～Fig. 4, a kind of mixed-flow of the utility model and axial flow hydraulic turbine gate linkage, comprise regulating ring of wicket gate 1 and two servomotors 2 that are connected by the big earhole 1-1 in its both sides with described regulating ring of wicket gate 1, the big earhole 1-1 of described regulating ring of wicket gate has complete shut-down position A, middle of stroke position B and fully open position C, and described servomotor 2 is between the complete shut-down position A and middle of stroke position B of the big earhole of described regulating ring of wicket gate.
The utility model is in order to solve servomotor pull bar other strength youngster's in movement process problem, adopt a kind of structure that makes pull bar pivot angle θ 1 minimum, the spacing that makes two servomotors 2 is arranged in servomotor 2 between control ring big earhole complete shut-down position and the middle of stroke position less than the spacing Ф between the big earhole in control ring both sides.
