Working principle: thermal energy storage process, in the case where automatic energy storage, the driving motor 21 drives first sprocket wheel 701
Rotation counterclockwise, first sprocket wheel 701 by first chain 61 drive second sprocket wheel 101 counterclockwise rotation to
First rotating shaft 100 is driven to rotate, in the case where manual energy storage, by rotating the energy storage shaft 9 counterclockwise to drive first
Shaft 100 rotates, and then driving the first gear 102, rotation, the first gear 102 drive the second gear counterclockwise
301 rotate clockwise with the third gear 302, the third gear 302 drive the 4th gear 401 counterclockwise rotation from
And the active connecting lever 402 and the rotation counterclockwise of auxiliary connecting lever 403 are driven, the auxiliary connecting lever 403 pulls described second
Chain 62 carries out energy storage to the energy-stored spring 24, when first auxiliary projection 4031 contact pushes first auxiliary wheel
2011, the energy storage switch connecting lever 201 rotates clockwise, and opens the energy storage travel switch 22, the energy storage travel switch 22
The driving motor 21 is stopped, while the energy accumulation clutch 23 is driven by the first connecting rod 231, by the second sprocket wheel
101 are detached from the linkage status with first rotating shaft 100, charging movement are carried out mechanical disconnection, first idler wheel 4021 connects at this time
The closing pawl 501 is touched, manipulation device has the tendency that moving towards combined floodgate direction under the effect of energy-stored spring power at this time, but transports
Dynamic position is limited, keeps energy storage state；
Making process, in the case where automatic closing, the switching electromagnet 602 pushes the combined floodgate buckle releaser 601 to turn counterclockwise
It is dynamic, in the case where closing by hand, reverse the conjunction departure handle 83, the conjunction bar 831 push the third auxiliary projection 6012 from
And the combined floodgate buckle releaser 601 is pushed to rotate counterclockwise, the subsequent closing pawl 501 loses the combined floodgate buckle releaser 601
Support, the closing pawl 501 turn counterclockwise under 4021 contact pressure of the first idler wheel effect on the active connecting lever 402
Dynamic, 4021 position of the first idler wheel is no longer limited, under the action of energy-stored spring 24, the rotation counterclockwise of auxiliary connecting lever 403
Turn, drives the active connecting lever 402 to rotate counterclockwise through first splined shaft 400, the closing pawl 501 is turned round at this time
Spring effect rotates clockwise homing, and the active connecting lever 402 rotates counterclockwise described on the contact driven connecting lever 51
