First rotation that can close a floodgate indicator 51, when first can close a floodgate indicator 51 be in the first output position when, indicate end face 5111
" ready " or corresponding first indication window 41 of " can close a floodgate " identification division, when first indicator 51 that can close a floodgate is in second
When zero output position, instruction end face 5111 corresponds to the first indication window 41 without mark part.Second 51 ' of indicator that can close a floodgate is same
Reason.
When initial position, such as Figure 12, switch is in I power supply (the first power supply) closing position, the output shaft 20 with mechanism
Dynamic driving cam surface 521 driving first indicator 51 that can close a floodgate overcomes the pulling force of reset spring 54 to be in second without output bit
It sets, the connecting rod of the operating mechanism is in left end, and the first actuator 531 is separated with first indicator 51 that can close a floodgate, and second
Second 51 ' of indicator that can close a floodgate of the driving of actuator 532 overcomes the pulling force of reset spring 54 to be in the second zero output position, and at this time two
Indication window is all without display.
When switch I power supply carries out separating brake, Slideslip, the first actuator 531 drive connecting rod 205 to the right under the drive of mechanism
The dynamic first upper actuating arm 511 that can close a floodgate indicator 51 makes first can close a floodgate after indicator 51 rotates clockwise certain angle, by
The effect of first actuator 531 is maintained on the second zero output position, and the second actuator 532 and second can close a floodgate 51 ' of indicator
It is detached from, second 51 ' of indicator that can close a floodgate starts to be rotated clockwise to the first output position under the action of reset spring 54, simultaneously
Driving cam surface 521 is rotated clockwise to intermediate double quartiles with output shaft 20 and sets, and can close a floodgate the convex of 51 ' of indicator with second
Wheel face 5121 is just inconsistent.At this point, such as Figure 13, the first indication window 41 shows that " II can without display, 41 ' of the second indication window
Close a floodgate ", II power supply (second source) be in can "on" position, the corresponding latching device of second source can be triggered, drive
The corresponding energy storage device of second source, which releases energy, carries out closing operation.
In II power supply making process, mechanism position feedback part 53(can be understood as the connecting rod of two energy storage devices of connection)
It remains stationary, first can close a floodgate indicator 51 still in the second zero output position.The driving cam surface 521 is in output shaft 20
Drive under rotate clockwise together, driving second can close a floodgate 51 ' of indicator lower actuating arm 512 on cam surface 5121, make
Second can close a floodgate 51 ' of indicator under the action of driving cam surface 521, overcome the power of reset spring 54 and rotate counterclockwise to
Two zero output positions, two indication windows are all without display, such as Figure 14 at this time.
When switch II power supply carries out separating brake, mechanism position feeds back the Slideslip to the left under the drive of operating mechanism of part 53,
The upper actuating arm 511 that the second actuator 532 driving second of mechanism position feedback part 53 can close a floodgate 51 ' of indicator, making second can
51 ' of combined floodgate indicator is maintained on the second zero output position, and the first actuator 531 and first can close a floodgate the disengaging of indicator 51, the
One indicator 51 that can close a floodgate starts to rotate counterclockwise to the first output position under the action of reset spring 54, while driving cam
Face 521 rotates counterclockwise to intermediate double quartiles with output shaft 20 and sets, the cam surface 5121 for the indicator 51 that can close a floodgate with first
It is just inconsistent.Such as Figure 15, the first indication window 41 shows " II can close a floodgate " at this time, and 41 ' of the second indication window is without display, I electricity
Source be in can "on" position, closing operation can be carried out.
In I power supply making process, mechanism position feedback part 53 remain stationary, second can close a floodgate 51 ' of indicator still in
Second indicating positions.The driving cam surface 521 rotates counterclockwise together under the drive of output shaft 20, and driving first can close
Cam surface 5121 on the lower actuating arm 512 of lock indicator 51 makes first can close a floodgate indicator 51 in the effect for driving cam 521
Under, overcome the power of reset spring 54 and be rotated clockwise to the second indicating positions, two indication windows are such as schemed all without display at this time
12。
When switch is when I power supply can close a floodgate and be transformed into II power supply and can close a floodgate, driving cam surface 521 sets guarantor in intermediate double quartiles
Hold motionless, mechanism position feedback part 53 slides to the right under the drive of operating mechanism, and the driving of the first actuator 531 first can close a floodgate
The upper actuating arm 511 of indicator 51 makes first indicator 51 that can close a floodgate that return spring force be overcome to be rotated clockwise to second without defeated
Out position, the second actuator 532 and second can close a floodgate 51 ' of indicator disengaging, and second can close a floodgate 51 ' of indicator in reset spring 54
Under the action of start to be rotated clockwise to the first output position, second can close a floodgate 51 ' of indicator cam surface 5121 and driving it is convex
Wheel face 521 is just inconsistent.Such as Figure 13, the first indication window 41 shows that " II can be closed without display, 41 ' of the second indication window at this time
Lock ", II power supply be in can "on" position, closing operation can be carried out.
When switch is when II power supply can close a floodgate and be transformed into I power supply and can close a floodgate, driving cam 521 sets holding in intermediate double quartiles
Motionless, operating mechanism position feedback part 53 slides to the left under the drive of operating mechanism, and the second actuator 532 driving second can close
The upper actuating arm 511 of 51 ' of lock indicator makes second 51 ' of indicator that can close a floodgate that return spring force be overcome to rotate counterclockwise to second
Zero output position, the first actuator 531 and first can close a floodgate the disengaging of indicator 51, and first can close a floodgate indicator 51 in reset spring
Start to rotate counterclockwise to the first output position under the action of 54, first can close a floodgate indicator 51 cam surface 5121 and driving it is convex
Wheel face 521 is just inconsistent.The first indication window 41 shows " I can close a floodgate " at this time, and 41 ' of the second indication window is without display, I power supply
In can "on" position, closing operation can be carried out.
