Description
Technical Field
The utility model relates to the field of old axial-flow propeller units and bulb turbine unit transformation, in particular to an electric control device of a propeller-rotating turbine unit blade without an external oil supply source.
Background
The existing axial flow propeller-rotating unit and bulb through-flow unit generally have the problems that oil pipes for controlling blades supply oil to a main machine through an oil receiver of the main machine, inevitable leakage is caused due to the change of movement and rotation between the oil receiver and a large shaft, the unit is easy to lose control, noise, vibration and environmental pollution, and an electric control device which is reliable in operation, simple in operation and capable of being accurately driven is needed in order to match with an improved regulating device of the blades of the hydraulic turbine unit.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of overcoming the defects in the prior art and provides an electric control device of a rotating propeller type turbine unit paddle without an external oil supply source.
The utility model is realized by the following technical scheme:
the utility model provides a need not the automatically controlled device of external oil supply's commentaries on classics oar formula hydraulic turbine unit paddle which characterized in that, including actuating mechanism and with actuating mechanism is through coordinating parallel first transmission line and the second transmission line that the gang switch is connected, actuating mechanism includes power drive, paddle proportion valves and the paddle servomotor of establishing ties each other, first transmission line include the touch-sensitive screen and with the controller that the touch-sensitive screen is connected, the second transmission line includes manual knob and electric manual knob.
And two ends of the actuating mechanism are connected with a blade servomotor position sensor in parallel.
The controller is a PLC controller, and an interface of the controller is RS 232.
The utility model has the beneficial effects that: the operation is reliable, the operation is simple, the accurate driving can be realized, and the emergency manual exit function is realized.
Drawings
FIG. 1 shows a logic diagram for operation according to an embodiment of the present invention.
In the figure: 1. a touch screen; 2. a controller; 3. a blade servomotor position sensor; 4. a power drive device; 5. a paddle proportional valve bank; 6. a blade servomotor; 7. a manual knob; 8. an electric and manual knob.
Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.
As shown in the figure, the utility model comprises an actuating mechanism, and a first transmission line and a second transmission line which are connected with the actuating mechanism through a cooperative switch in parallel, wherein the actuating mechanism comprises a power driving device, a blade proportional valve group and a blade servomotor which are connected in series, the first transmission line comprises a touch screen and a controller connected with the touch screen, the second transmission line comprises a manual knob and an electric manual knob, two ends of the actuating mechanism are connected with a blade servomotor position sensor in parallel, the controller is a PLC controller, and an interface of the controller is RS 232.
Before the initial startup, the signals are input into a controller 2 according to a guide vane/blade joint curve of a main machine; after the machine is stopped, the controller 2 controls the paddle blades to be in the starting opening degree; the head is input to the controller 2 in accordance with the operating head. After starting up, the controller 2 controls the paddle blade to be at 0 degree of opening; after the grid connection, the guide vane opening degree provided by the speed regulator outputs an electric signal to control the paddle control device of the rotary paddle type water turbine unit without an external oil supply source according to the guide vane/paddle conjunction curve through the electric control device.
When the automatic situation is that the cooperative connection is put in, the PLC controller is used for controlling and displaying a human-computer interface, when the electric cooperative connection is put in, the electromagnetic valve driving device is automatically controlled to control the opening and closing actions of the paddle proportional valve, the opening and closing positions of the paddle servomotor 6 are fed back to the PLC controller 2 through the paddle servomotor position sensor 3, and the touch screen 1 is used for displaying;
when manual control is switched, namely when the linkage is quitted, the opening and closing directions of the paddle proportional valve group 5 are controlled directly through the electric manual knob 8 and the power driving device 4, and the opening position does not need to be judged by a PLC.
The utility model has the beneficial effects that: the operation is reliable, the operation is simple, the accurate driving can be realized, and the emergency manual exit function is realized.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
