In the present embodiment, as shown in fig. 6-7, revolving body 4 also comprises elastic component 43, and when revolving body 4 is struck, elastic component 43 is compressed.Revolving body 4 can by the second projection 51 by the first projection 41, or by miniature circuit breaker 12 by shifting block 45 stir.Elastic component 43 is the flexure strip of undulate, and this flexure strip can be that plastics or metal material are made.Revolving body 4 also comprises revolving body through hole 42.As shown in Figure 4, extend a convex axle 3 in housing 1, revolving body through hole 42 is set in convex axle 3, first projection 41 when being struck, and revolving body 4 is around the center rotating of convex axle 3.First projection 41 is positioned at the front of revolving body 4, and shifting block 45 is positioned at the back side of revolving body 4.Housing 1 offers arc-shaped through-hole 2, shifting block 45 is inserted in miniature circuit breaker 12 through arc-shaped through-hole 2.
Preferably, elastic component 43 can also be back-moving spring.
The initial condition of revolving body 4, as shown in Figure 5, the revolving body 4 during initial condition is in and is not compressed or precompressed state.Elastic component 43 is arranged in the right side of revolving body 4, first projection 41 is arranged in the below of revolving body 4, first magnet steel 44 is positioned at the left side of revolving body 4, be arranged in the first magnetic steel sleeve through hole 441, one end of elastic component 43 is resisted against the right side of housing 1, first magnet steel 44 is positioned at the left side of housing 1, and the effect of the first magnet steel 44 will be described in detail later.
Electrically operated device of the present invention can realize two kinds of combined floodgate modes: closing by hand and automatic closing, two kinds of combined floodgate modes close a floodgate after the state of each parts be identical, the present invention is using the installation initial condition of the state after closing a floodgate as electrically operated device.
As shown in figs. 12-14, during (initially) state of combined floodgate, handle 8 is positioned at the rightmost side, revolving body 4 is in and is not compressed or precompressed state, angle between a end of the first arc convex 52 of the first clutch gear 5 and the c of the second arc convex 62 of the second clutch gear 6 holds is 35 °, the b of the first arc convex 52 holds and the d of the second arc convex 62 hold between angle be 125 °.Angle 125 ° is above-mentioned angle C is the rotational angle B's (rotational angle B is 113 °) being greater than the second clutch gear 6.
Electrically operated device of the present invention can realize three kinds of separating brake modes: manual brake separating, fault separating brake and long-range (arrearage) separating brake.
Be the state diagram after manual brake separating when electrically operated device is applied on miniature circuit breaker and fault separating brake see Figure 15-17, Figure 15-17.
The first, manual brake separating.Manual brake separating is realized by manual control handle 8.Handle 8 jumps to gate-dividing state from combined floodgate, has namely jumped to the leftmost side from the rightmost side, and handle 8 controls miniature circuit breaker 12 separating brake, and now the snap close of miniature circuit breaker 12 can not stir shifting block 45, does not have an impact to revolving body 4, and revolving body 4 is still in initial condition.Handle 8 drives the first sector gear 9 to rotate counterclockwise, first sector gear 9 drives the second clutch gear 6 to rotate clockwise, now, as shown in figure 17, the c of the second arc convex 62 holds a away from the first arc convex 52 to hold, the d end of the second arc convex is close to the b end of the first arc convex 52, the rotational angle B of the second clutch gear 6 is 113 °, after rotating, the d end of the second arc convex and the b of the first arc convex 52 still have the angle of 12 ° between holding, therefore the second clutch gear 6 can not drive the first clutch gear 5 to rotate, now the first clutch gear 5 is motionless.Second clutch gear 6 can drive the second sector gear 10 to rotate counterclockwise, and can describe in detail after the effect of the second sector gear 10.
The second, fault separating brake.When a failure occurs, miniature circuit breaker 12 separating brake, band fixed handle 8 jumps to gate-dividing state from combined floodgate, handle 8 drives the first sector gear 9 to rotate counterclockwise, first sector gear 9 drives the second clutch gear 6 to rotate clockwise, the rotational angle B of the second clutch gear 6 is identical with during manual brake separating, and the second clutch gear 6 also can not drive the first clutch gear 5 to rotate, and the second clutch gear 6 can drive the second sector gear 10 to rotate counterclockwise.
While miniature circuit breaker 12 fault separating brake, the inside snap close of miniature circuit breaker 12 can stir the shifting block 45 of revolving body 4, and revolving body 4 can be compressed, and elastic component 43 is compressed is once returned to initial condition again.When revolving body 4 rotates counterclockwise, the first magnet steel 44 of revolving body 4 also have rotated certain angle in the counterclockwise direction and is returned to initial condition again, and the effect of the first magnet steel 44 will be described in detail below.Now, revolving body 4 can not drive the first clutch gear 5 to rotate, and when revolving body 4 rotates counterclockwise, the first projection 41 can away from the second projection 51.
When after trouble shooting, can realize closing a floodgate by artificial manual driving handle 8, i.e. closing by hand.When handle 8 is promoted "on" position from separating brake, handle 8 controls miniature circuit breaker 12 and closes a floodgate, and drive the first sector gear 9 to rotate clockwise, first sector gear 9 drives the second clutch gear 6 to rotate counterclockwise, the rotational angle B that second clutch gear 6 is counterclockwise is still 113 °, now the second clutch gear 6 has just got back to the initial position of Figure 14, between the c end of the second arc convex 62 and a of the first arc convex 52 hold, angle still has 35 °, therefore the second clutch gear 6 still can not drive the first clutch gear 5 to rotate, second clutch gear 6 can drive the second sector gear 10 to rotate clockwise.
The third, long-range (arrearage) separating brake.As depicted in figures 18-20, when there is arrearage situation or Long-distance Control separating brake, control drive motors 7 by remote signal to rotate, motor 7 drives the first clutch gear 5 to rotate clockwise by gear train (structure of gear train will be described in detail later), after the first clutch gear 5 rotates clockwise certain angle, second projection 51 at first clutch gear 5 back side will be stirred first projection 41 in revolving body 4 front and drive revolving body 4 to rotate counterclockwise, the process Elastic part 43 that revolving body 4 rotates counterclockwise is compressed, the shifting block 45 at revolving body 4 back side also rotates counterclockwise in arc-shaped through-hole 2 simultaneously, until shifting block 45 stirs the snap close (not shown) in miniature circuit breaker 12, thread off in the inside realizing miniature circuit breaker.Now, revolving body 4 is in compacted state, because now motor 7 shuts down, gear train and the first clutch gear 5 all remain on motionless position, the second projection 51 is made to keep compressing the state of revolving body 4, now the resilience force of the elastic component 43 of revolving body 4 is not enough to make the first clutch gear 5 and gear train revolution, also just ensure that miniature circuit breaker 12 is in inner state of threading off, outside driving handle cannot be passed through, realize inside contact contact (connection of miniature circuit breaker front and back end), now handle 8 is automatically from the state jumping to separating brake of closing a floodgate, as shown in figure 18, in figure, handle 8 is gate-dividing state in the leftmost side, handle 8 can drive the first sector gear 9 to rotate counterclockwise, first sector gear 9 drives the second clutch gear 6 to rotate clockwise, the rotational angle B of the second clutch gear 6 is with manually identical with during fault separating brake, second clutch gear 6 can drive the second sector gear 10 to rotate counterclockwise.
Now, first clutch gear 5 can't drive the second clutch gear 6 to rotate, this is because the arc length of the second arc groove 61 is greater than the first arc convex 52, when first arc convex 52 rotates clockwise in the second arc groove 61, second arc convex 62 also rotates clockwise, when a end of final first arc convex 52 does not also touch the c end of the second arc convex 62, the first clutch gear 5 and the second clutch gear 6 have all stopped operating.That is, when installing initial condition a end of the first arc convex 52 along clockwise direction and the c of the second arc convex 62 hold between angle be 35 ° and add the rotational angle B of the second clutch gear 6 rotational angle (in the present embodiment, rotational angle is 27.5 °) that to be the summation of 113 ° be when being greater than the first clutch gear 5 at long-range (arrearage) separating brake.As shown in figure 20, after long-range (arrearage) separating brake, the angle between a end of the first arc convex 52 and the c of the second arc convex 62 hold is 120.5 °, and the angle between the d end of the second arc convex 62 and the b of the first arc convex 52 hold is 39.5 °.
Like this, achieve the effect that Long-distance Control miniature circuit breaker is threaded off, and handle 8 also shows as the state of separating brake.If when arrearage situation is constant, motor 7 shuts down, under the state that revolving body 4 remains on the snap close stirred in miniature circuit breaker 12.Now, if artificially handle 8 to be toggled it to the position of combined floodgate from separating brake, rotate clockwise from left to right by handle 8, handle 8 drives the first sector gear 9 to rotate clockwise together, first sector gear 9 can drive the second clutch gear 6 to rotate counterclockwise, now the second clutch gear 6 but can not drive the first clutch gear 5 to rotate, because the rotational angle B of the second clutch gear 6 is 113 °, and now a end of the first arc convex 52 and the c of the second arc convex 62 hold between angle be 120.5 °, be greater than 113 °, now c end is near to a termination, angle 120.5 ° between c end and a hold also is above-mentioned angle C.Therefore, when the c end of the second clutch gear 6 does not also touch a end of the first clutch gear 5, the second clutch gear 6 has just stopped operating.Second clutch gear 6, in the process rotated counterclockwise, can drive the second sector gear 10 to rotate clockwise.
After arrearage situation solves, Long-distance Control motor 7 rotates backward, i.e. automatic closing.Now the first clutch gear 5 rotates counterclockwise, and the second projection 51 is separated gradually with the first projection 41, and revolving body 4, under the effect of the resilience force of elastic component 43, is returned to the initial condition of revolving body 4, is not namely compressed or precompressed state.The shifting block 45 of revolving body 4 loses the control of the snap close to miniature circuit breaker 12, and miniature circuit breaker 12 possesses combined floodgate condition.Now, motor 7 continues reversion, first clutch gear 5 also continues to rotate counterclockwise, the d termination of b end gradually to the second arc convex 62 of the first arc convex 52 is near, due to the angle E (in the present embodiment, angle E is 39.5 °) that the rotation of motor 7 causes the rotational angle D of the first clutch gear 5 to be greater than between the two ends (namely b holds d to hold) that the first arc convex 52 and the second arc convex 62 move closer to.Motor 7 drives the first clutch gear 5 to rotate counterclockwise until the first arc convex 52 promotes the second arc convex 62 rotates counterclockwise together, second clutch gear 6 drives the first sector gear 9 to rotate clockwise, first sector gear 9 is with fixed handle 8 to rotate clockwise together, handle 8 jumps to the state of combined floodgate from separating brake, and handle 8 controls miniature circuit breaker 12 and realizes closing a floodgate.While second clutch gear 6 rotates counterclockwise, also drive rotating clockwise of the second sector gear 10.
In the present embodiment, the rotational angle A of handle, the rotational angle B of the second clutch gear 6, the rotational angle D of the first clutch gear 5, angle C and angle E is a certain set point value, but these angles do not represented in the present invention can only be the above-mentioned a certain special value enumerated.In actual applications, according to rotation amplitude, the modulus of gear, the number of teeth diameter of handle, the different parameters such as gearratio, rotational angle A, rotational angle B, rotational angle D, angle C and angle E can do corresponding adjustment.As long as can meet, rotational angle B is less than angle C, and rotational angle D is greater than angle E, all belongs to protection scope of the present invention.
