Embodiment
As shown in Figure 1 and Figure 2, a kind of remote control device of circuit breaker, the motor 3, gearbox 5, screw mandrel 4 and the driving lever 6 that comprise circuit breaker 11, control circuit 10, handle 1, shell 2 and be installed in shell 2 inside, described shell 2 is installed in circuit breaker 11 lateral location, described handle 1 is movably arranged on described shell 2 tops, can be along the rotating shaft left-right rotation of handle 1 with shell 2 link positions; Described gearbox 5 is connected with screw mandrel 4 with motor 3 respectively, screw mandrel 4 is positioned at the position of motor 3 tops and handle 1 bottom, two ends, screw mandrel 4 left and right sides ad-hoc location is respectively equipped with first sensitive switch 7 and second sensitive switch 8, described driving lever 6 is installed on the screw mandrel 4 between first sensitive switch 7 and second sensitive switch 8, make driving lever 6 in the process that moves all the time only with a sensitive switch is depressed, described control circuit 10 connects first sensitive switch 7 and second sensitive switches 8.
As Fig. 3 is the perspective view of driving lever, wherein on the screw mandrel 4 screw thread is arranged, and corresponding circular hole is arranged on the driving lever 6, have in the circular hole and 4 pairs of internal threads that are complementary of screw mandrel, and when screw mandrel 4 rotates, described relatively screw mandrel 4 move left and right of described driving lever 6.
As shown in Figure 4, described handle 1 bottom contacts with the surface of described driving lever 6, and driving lever 6 bottom surfaces are provided with the interception piece 13 of vertical installation, and is vertical with driving lever 6, and handle 1 bottom is provided with projection 14.Fig. 4 (1) is circuit breaker 11 handle 1 and driving lever 6 connection diagrams when disconnecting, and described protruding 14 are in below driving lever 6 surfaces when circuit breaker 11 disconnects, and on the right side of described interception piece 13; Be circuit breaker 11 close back handle 1 and driving lever 6 connection diagrams as Fig. 4 (2), described protruding 14 are in the surface of driving lever 6, contact with driving lever 6 surfaces; Fig. 4 (3) is that driving lever 6 returned initial position back handle 1 and driving lever 6 connection diagrams after circuit breaker 11 closed, and described handle 1 bottom surface contacts with the surface of driving lever 6, but the projection 14 on the handle 1 does not contact with driving lever 6 surfaces.Make that like this projection 14 remains at the right side of interception piece 13, can not arrive the left side of interception piece 13, and thereby interception piece 13 stops the phenomenon that projection 14 drives handles 1 counter-rotating when appearing at driving lever 6 and be moved to the left, and reaches 1 purpose toward a direction rotation of handle.
When circuit breaker 11 disconnects, as can be seen from Figure 1 driving lever 6 is depressed first sensitive switch 7, the operator passes through control circuit 10 transmission signals by Long-distance Control with signal, starter motor 3 rotations, the gear that drives gearbox 5 inside in the time of motor 3 rotations rotates, and the interlock effect between the gear reaches the speed change purpose.Gearbox 5 speed changes rotation back drives screw mandrel 4 with certain speed rotation, drives driving lever 6 simultaneously and slowly moves along the rotation of screw mandrel 4 right-hand members, and the interception piece 13 on the driving lever 6 moves right simultaneously, and projection 14 is produced thrust, and handle 1 is rotated counterclockwise under the effect of thrust; When rotation reached a certain extreme position, driving lever 6 stopped to move, and just in time second sensitive switch 8 was depressed this moment, and first sensitive switch 7 also is in the state of upspringing simultaneously.Like this, projection 14 is in the surface of driving lever 6, cut with driving lever 6 and contact, because handle 1 is arranged side by side with the handle 111 on the circuit breaker 11, and the circular hole 12 that passes handle 1 upper end by connecting rod 9 is fixedly connected, the rotation of handle 1 has just driven handle 111 rotations of circuit breaker 11 like this, reaches the combined floodgate of circuit breaker 11.
After circuit breaker 11 closes a floodgate, second sensitive switch 8 is in depressed state, promptly second sensitive switch 8 is in closure state, control circuit 10 transmission signals are given remote control, remote control passes on signal control motor 3 to stop the rotation, and with opposite direction rotation, promptly also with opposite direction rotation, driving lever 6 is moved to the left screw mandrel 4.Because projection 14 and the interconnected relationship of tackling piece 13, so driving lever 6 moves to initial position, handle 1 then rests on the position that circuit breaker 11 closes a floodgate, and driving lever 6 is depressed first sensitive switch 7 simultaneously, control circuit 10 transmission signals are to remote control, can know to stop motor 3 work.
In the whole process, all rotational components should guarantee not have stuck phenomenon flexibly, its connecting line is made in order neatly, in an embodiment, 8～10 kilograms of driving lever thrusts, driving lever 6 moves to the other end from initial position, returning initial position is a circulation, an one circulation is 1～2 second, and the thickness of driving lever is not more than 15 millimeters, and material is a kirsite.
