At present, handcart switch cabinet is a kind of switch cubicle commonly used in the controller switching equipment; It generally includes the moving contact that cooperatively interacts and cabinet and the circuit breaker cart of fixed contact is installed, and circuit breaker cart can push or pull out cabinet.When circuit breaker cart when pushing, being blocked in the cabinet valve in fixed contact the place ahead need to open, and the moving contact on the circuit breaker cart is cooperated with fixed contact grafting in being installed in cabinet; When circuit breaker cart was pulled out, the valve in the cabinet need to be closed again, so that fixed contact is protected.The valve type of drive of existing handcart switch cabinet is varied, and its complex structure, manufacturing cost height and reliability of operation are poor, can't guarantee action message and the operation of sleeve mechanism.
The utility model content
The purpose of this utility model is to provide a kind of valve arrangement of switch cubicle, and the valve arrangement of described switch cubicle is simple in structure, and cost is low, and is reliable.
For achieving the above object, the technical solution of the utility model is the valve arrangement of a kind of switch cubicle of design, comprise two vertical C type guide rails, be sliding combined with perpendicular overhead gage, the lower baffle plate of putting between these two C type guide rails, about the two ends, the left and right sides of overhead gage are articulated in by a pair of upper driving mechanism on two back shafts, the two ends, the left and right sides of lower baffle plate also are articulated in about this on two back shafts by a pair of lower transmission mechanism; Two back shafts are located on the horizontal linear parallel with overhead gage about this, and are positioned at the below of lower baffle plate; Upper driving mechanism comprises perpendicular upper connecting rod, the lower L shaped connecting rod of putting, the two ends of upper connecting rod are hinged with an end, the overhead gage of lower L shaped connecting rod respectively, the other end of lower L shaped connecting rod is articulated on the back shaft with its homonymy, the bending part of lower L shaped connecting rod is hinged with the bottom roller of and horizontal parallel with overhead gage, and bottom roller is positioned at the below of back shaft; Lower transmission mechanism comprises perpendicular lower link, the upper L shaped connecting rod of putting, the two ends of lower link are hinged with an end, the lower baffle plate of upper L shaped connecting rod respectively, the other end of upper L shaped connecting rod is articulated on the back shaft with its homonymy, upper L shaped connecting rod is furnished with the torsionspring of resetting in its hinged place, the bending part of upper L shaped connecting rod is hinged with the upper roller of and horizontal parallel with overhead gage, and upper roller is positioned at the top of back shaft.
Preferably, described overhead gage, lower baffle plate are slidingly matched by pulley and C type guide rail.
Preferably, described overhead gage, lower baffle plate are slidingly matched by slide block and C type guide rail.
Preferably, the external diameter of described upper roller and bottom roller is identical.
Preferably, the described lower link of lower baffle plate the same side, the upper L shaped connecting rod of being positioned at is at same perpendicular.
Preferably, the described upper connecting rod of lower baffle plate the same side, the lower L shaped connecting rod of being positioned at is at same perpendicular.
Preferably, described each upper roller, bottom roller all about between two back shafts.
The operation principle of the valve arrangement of this switch cubicle is: when the pushing hands car enters in the switchgear process, the bent plate that is fixed in the handcart both sides pushes respectively the upper and lower roller on the upper and lower transmission mechanism, bottom roller drives lower L shaped connecting rod and upper connecting rod, upper roller drives upper L shaped connecting rod and lower link, moves up and down thereby will rotatablely move to become, and drives overhead gage and moves upward, and lower baffle plate moves downward, namely open upper and lower valve, expose the high voltage source contact, in order to the access high voltage source; When the handle car withdraws from the switchgear process, the bent plate that is fixed in the handcart both sides is removed the pushing to upper and lower roller gradually, upper L shaped connecting rod relies on the reduction torsion spring on the back shaft to reset, and the drive lower baffle plate moves upward, lower L shaped connecting rod is pressed down by the weight of overhead gage and resets, and overhead gage moves downward, and namely closes valve, cover the high voltage source contact, thus the isolated high-voltage power supply.
Advantage of the present utility model and beneficial effect are: provide a kind of simple in structure, cost is low, the valve arrangement of reliable switch cubicle.And the valve arrangement of this switch cubicle is reasonable in design, and parts are few, and transmission is simple, and is easy to use, and reliability is high, flexible movements.Be applicable to open and close the high voltage source contact when handcart passes in and out in the switchgear, thus the isolated high-voltage power supply, operating personnel's safety when guaranteeing inspection and maintenance.Has good market popularization value.
