Mechanism closes a floodgate：Electromagnetic brake 14 is in loss of excitation and holds state tightly first on motor 1, and lock pawl 31 is in reduction torsion spring
It is fallen under b34 effects in 4 slot of worm gear.When adding in switching signal, 13 excitation of contactor is also turned on electromagnetic brake 14, motor 1
And 18 circuit of electromagnet, 14 excitation of electromagnetic brake, which disengages, constrains 1 rotor of motor, and motor 1 rotates, while electromagnet 18 triggers
Dropout pawl 22 drives worm screw 3 to rotate by first order The gear deceleration wheel 2, and worm gear 4 rotates, until one side of 4 right side sulculus of worm gear
Contact lock pawl 31, roller a33, trough rim rotates clockwise lock pawl 31 with roller opplied moment, due to dropout pawl
22 are triggered, and lock pawl 31, roller b35 are skidded off below along dropout pawl 22, and roller a33 abjection slots outer 4 right sides of worm gear are outer
Arc surface moves, and cam 9 then produces microswitch 5,18 circuit of tripping magnet, 18 dead electricity of electromagnet；Cam 9 goes to combined floodgate
During the microswitch 5 of position, switch microswitch contact, 13 circuit of cut-out contactor, contactor dead electricity, electromagnetic brake 14, electricity
1 dead electricity of machine, electromagnetic brake 14 constrain 1 rotor of motor, and 1 rotation stop of motor, overall process worm-wheel shaft 9 is rotated with worm gear 4, by defeated
Go out the rotational angle that gear set 12 completes body requirement, complete closing operation.Position instruction and counting are shown in this process simultaneously
It completes.
It closes a floodgate latter stage：When microswitch 5 cannot normally switch, 4 right side large trough inclined-plane of worm gear（Two bevel angle is by setting
Meter standard corner determines）Inverse stop bit clockwise is completed by supporting item a23, supporting item b24, meets body requirement, not make this
Body is damaged.
Mechanism separating brake：Sub-gate signal is added in, 13 excitation of contactor is also turned on electromagnetic brake 14,1 circuit of motor, electricity
14 excitation of magnetic brake, which disengages, constrains 1 rotor of motor, and motor 1 rotates, and motion process is identical with combined floodgate thereafter, direction on the contrary,
Switched by microswitch 5, motor rotation stop, complete sub-switching operation.
Separating brake latter stage：4 right side sulculus of worm gear goes to centre position, lock pawl 31 inverse time under reduction torsion spring b34 effects
Pin rotates, and roller a33 is fallen into sulculus, and lock 31 roller b35 of pawl is rotated simultaneously to be skidded off, and dropout pawl 22 is in reduction torsion spring
It rotates counterclockwise under a29 effects, is fallen by 21 /V of limit shaft on position.When microswitch cannot normally switch, worm gear 4 after
Continuous to rotate, one side of right side sulculus is contacted with lock pawl 31, roller a33, and lock pawl 31 is promoted to rotate clockwise, but by
Dynamic balance is formed in dropout pawl 22 and lock pawl 31, roller b35, lock pawl 31 cannot rotate, and prevent worm gear 4 from continuing
It rotates, realizes the /V in body centre position, avoid generating maloperation.
There is elongated slot design on 5 installing plate of microswitch, output angle can be finely adjusted, because idle running or machining deviation are led
The total travel of cause becomes smaller or deviates, and can meet by adjusting microswitch 5.Meanwhile the middle position caused by idle running reason repeats again
Position is difficult, can meet by adjusting microswitch 5.
