Combined floodgate pallet 16 on roller 18 rotation forces combined floodgate support arm 19 above, when located above on output toggle arm 15
When roller 18 anglec of rotation is more than combined floodgate pallet 16 length, in other words, roller 18 located above on output toggle arm 15
When crossing combined floodgate pallet 16, combined floodgate pallet 16 resets under the twisting force of combined floodgate pallet back-moving spring 17.Energy storage bullet
Spring 26 exports energy and arrives bottom dead centre to elongation, and energy-stored spring output energy terminates, and the highest cusp of cam 9 slips over position
Roller below output toggle arm 15, the cam 9 end of output to output toggle arm 15, output toggle arm 15 assembles at it
Main shaft 14 additional reset force effect under turn round clockwise, the combined floodgate pallet 16 that upper roller 18 has been resetted withstands,
Combined floodgate pallet 16 drives combined floodgate support arm to rotate by combined floodgate semiaxis padlock, completes closing operation.
Manual brake separating: press opening button, drives separating brake guide plate 31 to drive separating brake semiaxis 21 flip-flop movement, at this moment
Combined floodgate support arm 19 is deviate from the dropout groove of separating brake semiaxis 21, and output toggle arm 15 is additional the main shaft 14 assembled
Turn clockwise under reset force effect, till main shaft 14 reaches its restraining position, complete manual brake separating operation.
The present invention also can use the mode of electronic divide-shut brake, utilizes the components and parts such as motor, divide-shut brake coil to be additional to mechanism
On realize electric operating.
The present invention is reasonable in design, and simple in construction is clear, point, close a floodgate reliable, stable performance, easy for installation, daily need not tie up
Protecting, service life is long.
It should be understood that on the premise of the principle not changing the present invention and design, change made or deformation,
Belong to protection scope of the present invention.
