Above-mentioned chopper at least has advantages below：
During energy storage, manually rotating operation axle, operating shaft drives drive axis by gear-driven assembly, or opens
Dynamic power source, power source drives operating shaft to rotate by gear-driven assembly, operating shaft and then driven by gear-driven assembly
Drive axis, the drive plate connecting lever on power transmission shaft and energy-storage crank arm rotate counterclockwise with power transmission shaft, and energy-stored spring is with rotation quilt
Stretching reaches energy storage state, and now energy-storage crank arm is got on energy storage auxiliary switch, and energy storage auxiliary contact is cut off, and power source stops
Work, thermal energy storage process terminates.
After energy storage terminates, the pulley on drive plate connecting lever just props up on combined floodgate dropout connecting lever, and the dropout connecting lever that closes a floodgate
Blocked by combined floodgate swing arm, therefore can effectively block energy-stored spring restoring force, so that energy-storage crank arm can not be rotated counterclockwise, reach maintenance
Energy storage state.
During combined floodgate, rotate counterclockwise combined floodgate swing arm, release the restriction to combined floodgate dropout connecting lever for the combined floodgate swing arm, due to energy storage bullet
The restoring force of spring, forces drive plate connecting lever to rotate counterclockwise rapidly, and the impulsive force that drive plate connecting lever rotates is beaten in separating brake connecting lever wheel
On, so that tripping spring connecting lever is rotated clockwise, and make the spring-compressed accumulation of energy of tripping spring sleeve, output shaft also turns clockwise
Dynamic, therefore drive the connecting shaft connecting lever in back plate to rotate clockwise, connecting shaft connecting lever is separated with buffer, now closes a floodgate and completes.
At the end of combined floodgate, separating brake connecting lever roller just falls and buckles in separating brake, and separating brake connecting lever is because of separating brake swing arm gear, therefore
The position of separating brake connecting lever roller can be kept constant, so that chopper is maintained at closing position.At the end of combined floodgate, energy-stored spring
Energy release, power source can be again started up energy-stored spring energy storage.At this moment, because spring keeps out piece and 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 rotating counterclockwise, anti-reclosing
Spring stops combined floodgate swing arm from rotating by keeping out piece and interacting with spring, chopper therefore can be avoided to close a floodgate again, it is to avoid again
The adverse consequencess that the enormous impact force producing during secondary combined floodgate causes to whole mechanism.
During separating brake, release the restriction to separating brake connecting lever roller for the separating brake button 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 rotate, until connecting shaft connecting lever is contacted with buffer, separating brake completes.

Above-mentioned chopper 10 at least has advantages below：
See also Fig. 4～Fig. 6, during energy storage, manually rotating operation axle 100, operating shaft 100 passes through gear drive
Assembly 400 drives power transmission shaft 300 to rotate, or starts power source 200, and power source 200 passes through gear-driven assembly 400 and drives behaviour
Make axle 100 to rotate, operating shaft 100 so that by gear-driven assembly 400 drive power transmission shaft 300 rotate, the biography on power transmission shaft 300
Moving plate connecting lever 510 and energy-storage crank arm 530 rotate 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 just props up on combined floodgate dropout connecting lever 610, and it is de- to close a floodgate
Button connecting lever 610 is blocked by combined floodgate swing arm 620 again, therefore can effectively block energy-stored spring 540 restoring force, make energy-storage crank arm 530 not
Can rotate counterclockwise, reach maintenance energy storage state.
See also Fig. 7～Fig. 9, during combined floodgate, rotate counterclockwise combined floodgate swing arm 620, release combined floodgate swing arm 620 to combined floodgate
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 rotates is beaten on separating brake connecting lever wheel 910, so that tripping spring connecting lever 920 is rotated clockwise, and makes point
The spring-compressed accumulation of energy of lock spring spool 930, output shaft 700 also rotates clockwise, and therefore drives the connecting shaft connecting lever in back plate 102
820 rotate clockwise, and connecting shaft connecting lever 820 is separated with buffer 810, now close a floodgate and complete.
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, the position therefore, it is possible to keep separating brake connecting lever roller 960 is 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 energy-stored spring 540 energy storage.At this moment, due to
The presence of piece 621 and anti-reclosing spring 710 kept out by spring, and it is just right that piece 621 just kept out by anti-reclosing spring 710 with spring,
When combined floodgate swing arm 620 has the trend rotating counterclockwise, anti-reclosing spring 710 is interacted by keeping out piece 621 with spring
Stop combined floodgate swing arm 620 from rotating, chopper 10 therefore can be avoided to close a floodgate again, it is to avoid the enormous impact force producing when closing a floodgate again
The adverse consequencess that whole mechanism is caused.
See also Figure 10～Figure 12, during separating brake, by rotating separating brake swing arm 970 releasing separating brake button 950, separating brake is turned
The restriction of arm roller 960, the energy release that the spring-compressed in tripping spring sleeve 930 produces drives output shaft 700 and output
Separating brake connecting lever wheel 910 on axle 700, separating brake connecting lever 940 and connecting shaft connecting lever 820 rotate counterclockwise, until connecting shaft connecting lever 820 with slow
Rush device 810 to contact, separating brake completes.
Embodiment described above only have expressed the several embodiments of the present invention, and its description is more concrete and detailed, but simultaneously
Can not therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
Say, without departing from the inventive concept of the premise, some deformation can also be made and improve, these broadly fall into the protection of the present invention
Scope.Therefore, the protection domain of patent of the present invention should be defined by claims.
