Energy release, power source can be again started up energy-stored spring energy storage.At this moment, as spring keeps out piece with anti-reclosing spring
Exist, anti-reclosing spring just keeps out with spring that piece is just right, when combined floodgate swing arm has the trend for rotating counterclockwise, anti-reclosing
Spring prevents combined floodgate swing arm from rotating by keeping out piece interaction with spring, therefore chopper can be avoided to close a floodgate again, it is to avoid again
The adverse consequencess that the enormous impact force produced during secondary combined floodgate is caused to whole mechanism.
During separating brake, restriction of the separating brake button to separating brake connecting lever roller is released by rotating separating brake swing arm, in tripping spring sleeve
The energy release that produces of spring-compressed drive separating brake connecting lever wheel on output shaft and output shaft, separating brake connecting lever and connecting shaft connecting lever inverse
Hour hands are rotated, until connecting shaft connecting lever is contacted with buffer, separating brake is completed.

Above-mentioned chopper 10 at least has advantages below：
Fig. 4～Fig. 6 is seen also, during energy storage, manually rotating operation axle 100, operating shaft 100 pass through gear drive
Component 400 drives power transmission shaft 300 to rotate, or starts power source 200, and power source 200 drives behaviour by gear-driven assembly 400
Make axle 100 to rotate, operating shaft 100 further drives power transmission shaft 300 to rotate by gear-driven assembly 400, the biography on power transmission shaft 300
Moving plate connecting lever 510 and energy-storage crank arm 530 are rotated counterclockwise with power transmission shaft 300, and energy-stored spring 540 is stretched with rotation and reaches energy storage
State, now energy-storage crank arm 530 get on energy storage auxiliary switch 560, energy storage auxiliary contact be cut off, power source 200 stop work
Make, thermal energy storage process terminates.
After energy storage terminates, the pulley 520 on drive plate connecting lever 510 is just propped up on combined floodgate dropout connecting lever 610, and closes a floodgate de-
Button connecting lever 610 is blocked by combined floodgate swing arm 620 again, therefore can effectively block 540 restoring force of energy-stored spring, makes energy-storage crank arm 530 not
Can rotate counterclockwise, reach maintenance energy storage state.
Fig. 7～Fig. 9 is seen also, during combined floodgate, combined floodgate swing arm 620 is rotated counterclockwise, 620 pairs of combined floodgates of combined floodgate swing arm are released
The restriction of dropout connecting lever 610, due to the restoring force of energy-stored spring 540, forces drive plate connecting lever 510 to rotate counterclockwise rapidly, passes
The impulsive force that Moving plate connecting lever 510 is rotated is beaten on separating brake connecting lever wheel 910, rotates clockwise tripping spring connecting lever 920, and makes point
The spring-compressed accumulation of energy of lock spring spool 930, output shaft 700 are also rotated clockwise, therefore drive the connecting shaft connecting lever in back plate 102
820 rotate clockwise, and connecting shaft connecting lever 820 is separated with buffer 810, and now closing a floodgate completes.
At the end of combined floodgate, separating brake connecting lever roller 960 just falls on separating brake button 950, and separating brake connecting lever 940 is because of separating brake swing arm
970 gears, therefore, it is possible to keep the position of separating brake connecting lever roller 960 constant, so that chopper 10 is maintained at closing position.Close
At the end of lock, the energy release of energy-stored spring 540, power source 200 can be again started up 540 energy storage of energy-stored spring.At this moment, due to
Spring keeps out the presence of piece 621 and anti-reclosing spring 710, and it is just right that anti-reclosing spring 710 just keeps out piece 621 with spring,
When combined floodgate swing arm 620 has the trend for rotating counterclockwise, anti-reclosing spring 710 is interacted by keeping out piece 621 with spring
Prevent combined floodgate swing arm 620 from rotating, therefore chopper 10 can be avoided to close a floodgate again, it is to avoid the enormous impact force produced when closing a floodgate again
The adverse consequencess caused by whole mechanism.
Figure 10～Figure 12 is seen also, during separating brake, separating brake is turned by rotating 970 releasing separating brake button 950 of separating brake swing arm
The restriction of arm roller 960, the energy release that the spring-compressed in tripping spring sleeve 930 is produced drive output shaft 700 and output
Separating brake connecting lever wheel 910, separating brake connecting lever 940 and connecting shaft connecting lever 820 on axle 700 is rotated counterclockwise, until connecting shaft connecting lever 820 with it is slow
Rush device 810 to contact, separating brake is completed.
Embodiment described above only expresses several embodiments of the present utility model, and its description is more concrete and detailed,
But therefore can not be interpreted as the restriction to utility model patent scope.It should be pointed out that for the common skill of this area
For art personnel, without departing from the concept of the premise utility, some deformations and improvement can also be made, these belong to
Protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be defined by claims.
