Embodiment
The utility model is intended to propose a kind of reliable transmission and possesses the combined floodgate drive unit of auto-manual two kinds of patterns, and uses the circuit breaker of this combined floodgate drive pattern.
Combined floodgate drive unit of the present utility model comprises handle mechanism, transmission mechanism and motor.Handle mechanism has actuator.Motor is closed a floodgate by transmission mechanism driving handle mechanism.Wherein leave operating space between transmission mechanism and handle mechanism, the enough handle mechanisms in operating space carry out manual brake separating or closing operation.
In one embodiment, transmission mechanism is realized by slider-crank mechanism, and thus, this combined floodgate drive unit comprises handle mechanism, slider-crank mechanism and motor.Handle mechanism has actuator.Motor is closed a floodgate by slider-crank mechanism driving handle mechanism.Wherein leave operating space between slider-crank mechanism and handle mechanism, the enough handle mechanisms in operating space carry out manual brake separating or closing operation.
First with reference to figure 2 ~ Fig. 6, the combined floodgate drive unit according to an embodiment of the present utility model is disclosed.Referring to figs. 2 and 3 shown, this combined floodgate drive unit comprises: handle mechanism 102, slider-crank mechanism 104 and motor 103.Handle mechanism 102 can rotate around the axis, and handle mechanism 102 comprises the handle 122 and actuator 121 that are positioned at rotating shaft both sides, and in the illustrated embodiment in which, actuator 121 is projections.Slider-crank mechanism 104 is made up of crank 141, connecting rod 142 and slide block 143, and one end of connecting rod 142 is arranged on crank 141, and the other end of connecting rod 142 is arranged on slide block 143.Motor 103 is connected with crank 141.Disclose the operation principle of combined floodgate drive unit with reference to figure 6, Fig. 6, motor 103 can rotate by driving crank 141, and crank 141 is with movable slider 143 to reciprocatingly slide along a straight line by connecting rod 142.
Get back to Fig. 2 and Fig. 3, Fig. 2 discloses the structure chart of the combined floodgate drive unit according to an embodiment of the present utility model, and wherein crank is positioned at operating position.Fig. 3 discloses the structure chart of the combined floodgate drive unit according to an embodiment of the present utility model, and wherein crank is positioned at initial position.The making process of this combined floodgate drive unit is as follows: handle mechanism 102 is in open position (shown in figure 1), and crank is positioned at initial position, and slide block and actuator are without interaction.It should be noted that, the implication of " without interact " refers to and does not produce any active force each other herein, and both can contact with each other, and also can be close to each other but still leaves gap, but does not produce interaction force each other.With reference to figure 2, motor 103 driving crank 141 is rotated to operating position by initial position, is with movable slider 143 linearly to slide by connecting rod 142, promotes actuator 121 and moves, and drives handle mechanism 102 to turn to closing position.Complete automatic closing.
Then, motor 103 continues driving crank 141 and is rotated to initial position by operating position, and connecting rod 142 linearly slides with movable slider 143 and is separated with actuator 121 and returns original position.Handle mechanism 102 rests on closing position.Now, handle mechanism 102, owing to not being subject to the restriction of slide block 143, can carry out the operation of manual brake separating or combined floodgate, and this combined floodgate drive unit provides manual mode thus.As can be seen here, slider-crank mechanism, after completing automatic closing, all can return initial position at every turn, reserves sufficient operating space to give handle mechanism 102.The enough handle mechanisms 102 in this operating space carry out manual brake separating or closing operation.When crank 141 is in initial position, no matter handle mechanism 102 makes to be in open position or closing position, and actuator 121 all can not produce with slide block 143 and interact, and therefore slider-crank mechanism can not affect combined floodgate or the sub-switching operation of handle mechanism.
With reference to figure 4a, 4b, 4c and Fig. 5, disclose the structure chart of slider-crank mechanism and motor in combined floodgate drive unit.As shown in the figure, crank 141 has motor axis hole 143 and connecting rod axis hole 144, motor axis hole 143 and connecting rod axis hole 144 lay respectively at the two ends of crank 141, motor axis hole 143 is connected with the driving shaft 131 of motor 103, connecting rod 142 is arranged in connecting rod axis hole 144, and connecting rod 142 can rotate in connecting rod axis hole 144.Slide block 143 has installing hole towards the side of connecting rod 142, and connecting rod 142 is arranged in installing hole, and connecting rod 142 also can rotate in installing hole.Form mounting groove 145 around installing hole, because connecting rod 142 can rotate around installing hole in the course of the work, therefore mounting groove 145 provides the space that connecting rod 142 carries out rotating.Slider surface 143 has groove 146 to the side of actuator 121, the shape of groove 146 and the mating shapes of actuator 121 (projection 121).When actuator and shoe contact and when slipper push actuator, groove 146 and actuator 121 can engage each other.It should be noted that, if actuator adopts other form, slide block 143 also can adopt corresponding mode mate.
According to an embodiment of the present utility model, also propose a kind of circuit breaker, shown in figure 1, Fig. 1 discloses the circuit breaker according to an embodiment of the present utility model, which uses combined floodgate drive unit.This circuit breaker comprises pedestal 101, handle mechanism 102 and tripping mechanism 106, and handle mechanism 102 is arranged on pedestal 101 by rotating shaft, and this circuit breaker also comprises combined floodgate drive unit and control device.Combined floodgate drive unit comprises handle mechanism 102, slider-crank mechanism 104 and motor 103, and motor 103 can drive handle mechanism 102 to close a floodgate by slider-crank mechanism 104.Control device 105 controls the switch of motor 103, and control device 105 also controls the dropout of tripping mechanism 106.
By control device 105, under this circuit breaker can be arranged on automatic mode or manual mode two kinds of patterns.Control device 105 controls circuit breaker when automatic mode, drives handle mechanism 102 to close a floodgate by motor 103 by slider-crank mechanism 104, and the process of combined floodgate, with reference to described in earlier figures 2 ~ Fig. 6, repeats no more herein.Threaded off by tripping mechanism 106 and carry out separating brake.Realize automatic closing and automatic brake separating thus.It should be noted is that, in circuit breaker, pedestal 101 is provided with chute, the slide block 143 in slider-crank mechanism 104 is arranged in chute, and chute is type linearly, and thus, slide block 143 linearly can reciprocatingly slide in chute under the driving of motor 103.As previously described, motor 103 is after driving handle mechanism 102 to complete combined floodgate by slider-crank mechanism 104, slider-crank mechanism 104 can be continued to drive to initial position, reserve operating space to handle mechanism 102, make handle mechanism 102 to carry out manual operation.It should be noted that, in automatic mode, because handle has enough activity spaces, still can manually carry out closing a floodgate or separating brake by operating grip, also can be understood as, in automatic mode, namely provide automatic closing mode, also provide closing by hand mode.
