The bottom of said left and right side plate is respectively arranged with fixed pulley, is wound with steel cable on the said fixed pulley, and said steel cable one end and upper spacer slider roller are affixed, and the other end and lower clapboard slider roller are affixed; Be hinged with kinematic link on the said upper spacer slider roller, the upper end of said kinematic link is hinged with transmission crank arm, and said transmission crank arm is provided with guide post and the connecting axle that is used for being connected with switch cubicle.
As preferably, the both sides, top of said upper spacer are rotatably connected through axle sleeve and mechanism's left side plate respectively, and the two bottom sides of said lower clapboard is rotatably connected through axle sleeve and mechanism's left side plate respectively.
As preferably, said upper spacer and lower clapboard structure be symmetry fully.
As preferably, the turning α of said connecting lever is 15-20 °.
The utility model combines engineering mechanics and mechanical drive principle fully, has following beneficial effect: simple in structure, and the unlatching of valve, closed flexibility and reliability; Transmission mechanism takes up room little; The dividing plate of valve mechanism outwards rotates and is positioned at beyond the safe distance of high-voltage charged body, makes network system safe and reliable to operation; Valve can be closed under the situation of not accepting external force automatically, thereby better guarantees operating personnel's safety, increases the degree of protection of switch cubicle.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Wherein: 1-upper spacer, 2-lower clapboard, 3, the 7-hinge, 4, the 8-axle sleeve, 5-side plate, 6,9-slider roller, 10-fixed pulley, 11-steel wire, 12-kinematic link, 13-transmission crank arm, 14-connecting axle, 15-guide post .16, the directed slideway of 17-.
Embodiment
Below in conjunction with accompanying drawing and embodiment the structure of the utility model is further specified.
The utility model combines engineering mechanics fully with mechanical drive principle, valve can be closed under the situation that does not receive external force automatically.
Referring to Fig. 1; The utility model mainly comprises the valve upper spacer 1 and lower clapboard 2 that is installed on the left and right side plate 5, is used for intercepting high-voltage charged body, is processed by two blocks of identical steel plates respectively; Connect with hinge 3 in the outside between two demarcation strips, guarantee that demarcation strip can rotate freely.Upper spacer 1 is symmetrical fully with lower clapboard 2 structures.
The both sides, top of upper spacer 1 are rotatably connected on the left and right side plate 5 through axle sleeve 4 respectively, guarantee upper spacer 1 under the situation that axle sleeve 4 is fixed, and can serve as that axle rotates freely with its center.The two bottom sides of upper spacer 1 makes slider roller 6 can drive the upper spacer easy on and off and moves through in the intilted directed slideway 17 on the left and right side plate 5 of slider roller 6 embedding valve mechanisms of special processing.Same symmetrical structure connects two demarcation strips of downside with hinge 7, is connected to the bottom of the left and right side plate 5 of valve mechanism respectively through the slider roller 9 of downside axle sleeve 8 and downside, and lower clapboard 2 can be free to slide and rotate equally.
The reeded fixed pulley 10 of left and right side plate 5 bottom mounting straps at valve mechanism.Steel wire 11 1 ends are connected on the slider roller 6 of upper spacer, and steel wire 11 is passed lower end fixed pulley 10, and the other end is fixed on the slider roller 9 of lower clapboard.One end of kinematic link 12 and the slider roller 6 of valve mechanism upper spacer are hinged, and the other end is hinged to the upper end of the transmission crank arm 13 of valve mechanism.The other end of transmission crank arm 13 is fixed on the fixed side of switch cubicle through connecting axle 14.With upper-part connection request can activity freely, rotation flexibly.The turning α of transmission crank arm 13 according to circumstances, optional span is between 15-20 °.
When operation valve mechanism (shaking) into circuit breaker cart; Circuit breaker cart moves forward under the active force of leading screw; Simultaneously the guide post 15 of valve mechanism transmission crank arm 13 is upwards pressed, thereby through kinematic link 12, the upper spacer 1 that drives valve mechanism is done directed moving along the intilted directed slideway that is provided with on the left and right side plate 5 of valve mechanism 16; Under the drive of steel wire 11, the lower clapboard 2 of valve mechanism moves along the directed slideway 17 of valve mechanism left side plate in the other direction.Because the upper spacer 1 of valve mechanism is connected through the same firm line of metal with lower clapboard 2, thereby guarantee the synchronism of last lower clapboard, accomplished the overall process of opening valve mechanism.
Otherwise; If circuit breaker cart is shaken out switch cubicle, because upper spacer 1 is identical with lower clapboard 2 weight, guide post 15 moves downward under the effect of gravity; Drive upper spacer 1 moves down along the directed slideway fixed 16 of the left and right side plate 5 of valve mechanism; Drive lower clapboard 2 simultaneously and move up, thereby make valve mechanism auto-closing under the effect of no external force, accomplish the process of closure flap mechanism.
The utility model has overcome the existing valve of existing valve mechanism and has opened, closed complicacy; Deficiencies such as big, operation inconvenience take up room; Realize valve mechanism open and close flexibility and reliability, easy to use, take up room little; And can guarantee the safe distance of valve dividing plate and high-voltage charged body, guarantee with electric process and maintenance test safety, reliably.
More than the novel a kind of shutter mechanism of switch cabinet that provides of this use has been carried out detailed introduction; For one of ordinary skill in the art; Thought according to the utility model embodiment; The part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
