Abstract
The utility model provides a speed adjusting controller of a water turbine, comprising a speed adjusting rod, an aperture indicating mechanism, a guide blade aperture adjusting mechanism, a drive motor which drives the speed adjusting rod to rotate by a drive mechanism, and a speed adjusting control mechanism used for controlling the drive motor, wherein the speed adjusting rod can be controlled to rotate so as to drive the guide blade aperture adjusting mechanism to realize the speed adjustment. The speed adjusting controller drives the speed adjusting rod to rotate by the motor so as to drive the guide blade aperture adjusting mechanism to realize the speed adjustment, the speed adjusting controller is simpler in structure, a limit mechanism is disposed on the aperture indicating mechanism, a stroke control switch sends a signal to the speed adjusting control mechanism when an aperture indicating needle contacts a contact point of the stroke control switch, and the speed adjusting control mechanism controls the working condition of the drive motor to achieve the limiting function.
Description
Technical field
The utility model relates to a kind of water turbine governing control gear.
Background technique
Hydrogovernor is to regulate the equipment of hydraulic turbine discharge and fluidised form by the stator mechanism of water turbine and blade mechanism, this controlling device needs higher power, reason owing to convention, even small-sized speed regulator also adopts mechanical-hydraulic mechanism mostly, and often adopt one-level or the bigger hydraulic actuator of 2-level hydraulic, the said goods all is to carry out the work volume with the translative mode of electric energy → hydraulic pressure energy → mechanical energy, and its shortcoming and defect is: complex structure, volume are big.Commercially available also have a mechanical simple hydrogovernor (as Fig. 1), for manually control, operation hard.
The model utility content
Main purpose of the present utility model is to overcome that governor mechanism complexity, volume that prior art adopts mechanical-hydraulic mechanism are big, troublesome poeration, poor reliability, and adopt small-sized machine formula speed regulator to need hard etc. the shortcoming of manually-operable, operation, propose a kind of by motor-driven water turbine governing control gear.
The utility model adopts following technological scheme:
A kind of water turbine governing control gear, comprise speed control rod, aperture indicating device and guide vane opening regulating mechanism, thereby this speed control rod can be controlled rotation drive the guide vane opening regulating mechanism and move and realize it is characterized in that speed governing: also comprise by driving mechanism driving drive motor that speed control rod rotates and the speed regulation control mechanism that is used to control this drive motor.
Further, described driving mechanism comprises transmission shaft, be individually fixed in gearwheel and the small gear on the transmission shaft and be arranged at follower on the described speed control rod, is meshing with each other respectively between described gearwheel and the described motor gear and between described small gear and the described follower.
Further, also comprise position-limit mechanism, comprise two travel control switchs, described aperture indicating device comprises aperture direction board and aperture pointer, and two travel control switchs are arranged at this aperture direction board two ends respectively.
By above-mentioned to description of the present utility model as can be known, compared with prior art, the utlity model has following beneficial effect: thus the utility model adopts the motor driving speed control rod to rotate to be driven the guide vane opening regulating mechanism and moves and realize speed governing, structure is simpler; The driving mechanism that adopts can be that gear transmission also can be a belt transmission, can select according to actual conditions; In aperture indicating device position-limit mechanism is set, when aperture pointer touching travel control switch contact, travel control switch sends a signal to speed regulation control mechanism, thereby the working state of speed regulation control mechanism controlling and driving motor reaches limit function.
