Further, described linkage unit comprises connecting lever and connecting plate, one end of connecting lever is connected with isolating switch rotating shaft, the other end alongst offers movable span one, the upper end thereof of connecting plate is on the sidewall of switch cubicle, and lower end alongst offers movable span two, and top connecting plate being positioned at movable span two is provided with protrusion fulcrum, level extends outward to one end of the axis of guide outside horizontal guide rail and activity is engaged in movable span two, protrudes fulcrum activity and is engaged in movable span one.
After adopting technique scheme, the utility model compared with prior art, have the following advantages: the utility model switch cubicle safety screen valve mechanism can along with the closing of isolating switch, disconnect and automatically open, cover, so thoroughly can avoid the misoperation of staff, the personal safety of safeguard work personnel, have safe and reliable, flexible operation, the advantage such as easy to operate.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model switch cubicle safety screen valve mechanism is in the state of opening.
Fig. 2 is the structural representation that the utility model switch cubicle safety screen valve mechanism is in the state of covering.
Shown in figure: 1, insulation barrier 2, level are to the axis of guide 3, the vertical axis of guide 4, upright guide rail 5, horizontal guide rail 6, connecting lever 7, connecting plate 8, movable span 1, movable span 2 10, protrusion fulcrum 11, mounting panel 12, isolating switch rotating shaft.
Embodiment
Below by drawings and Examples, the utility model is further elaborated.
As depicted in figs. 1 and 2: a kind of switch cubicle safety screen valve mechanism, comprises the insulation barrier 1 being movably set in inside switch cabinet, inside switch cabinet is divided into superposed isolating switch chamber and is positioned at the vacuum switch chamber of bottom by insulation barrier 1.Front-end and back-end bottom insulation barrier 1 are respectively arranged with level to the axis of guide 2 and the vertical axis of guide 3, and level all be arranged in parallel with isolating switch rotating shaft 12 to the axis of guide 2, the vertical axis of guide 3.The bilateral symmetry of insulation barrier 1 arranges the guide assembly of the inverted L-shaped that two groups are made up of horizontal guide rail 5 and upright guide rail 4.The two ends of the vertical axis of guide 3 are slidably fitted on two upright guide rails 4 respectively, and level is slidably fitted on two horizontal guide rails 5 respectively to the two ends of the axis of guide 2.Level is connected with isolating switch rotating shaft 12 to the axis of guide 2 by linkage unit, and level can slidably reciprocate along horizontal guide rail 5 and then drive insulation barrier 1 along with the closing of isolating switch to the axis of guide 2, disconnect and open, cover under the rotation of isolating switch rotating shaft 12.
In the present embodiment, linkage unit comprises connecting lever 6 and connecting plate 7.One end of connecting lever 6 is connected with isolating switch rotating shaft 12, and the other end alongst offers movable span 1.The upper end thereof of connecting plate 7 is on the sidewall of switch cubicle, and lower end alongst offers movable span 29.Top connecting plate 7 being positioned at movable span 29 is provided with protrudes fulcrum 10.Level extends outward to one end of the axis of guide 2 outside horizontal guide rail 5 and activity is engaged in movable span 29, protrudes fulcrum 10 activity and is engaged in movable span 1.Design like this, when isolating switch rotating shaft 12 is rotated, drives connecting plate 7 to rotate by connecting lever 6, and then drives level movable to the axis of guide 2 along horizontal guide rail 5 by connecting plate 7.In the process, protrude fulcrum 10 movable relatively back and forth in movable span 1, level is movable relatively back and forth in movable span 29 to one end of the axis of guide 2, thus the circular motion of connecting lever 6 is changed into the back and forth rectilinear motion of level to the axis of guide 2.
In addition, the both sides of insulation barrier 1 are provided with mounting panel 11, and two horizontal guide rails 5 are separately fixed on two mounting panels 11.Above-described isolating switch rotating shaft 12 is prior art, pulls isolating switch rotating shaft 12 rotation realize the disconnection of isolating switch and close by spanner.
Operation principle: when disconnection isolating switch is rotated in isolating switch rotating shaft 12 facing one direction, drive level to the axis of guide 2 along horizontal guide rail 5 forward slip by connecting lever 6, meanwhile, the vertical axis of guide 3 is along upright guide rail 4 upward sliding, thus drive insulation barrier 1 to overturn downwards, when isolating switch disconnects completely, insulation barrier 1 is just in time the level of state, namely be in and cover state completely, now, the hand of operating personnel cannot extend in isolating switch chamber and operate, and concrete structure as shown in Figure 1; When isolating switch rotating shaft 12 closes isolating switch towards the rotation of another direction, slided backward along horizontal guide rail 5 to the axis of guide 2 by connecting lever 6 drive level, meanwhile, the vertical axis of guide 3 is along upright guide rail 4 slide downward, thus drive insulation barrier 1 upwards to overturn, when isolating switch closes completely, insulation barrier 1 is just in time in vertical state, namely be in and open state completely, now, the hand of operating personnel can extend in isolating switch chamber and operate, and concrete structure as shown in Figure 2.
The utility model switch cubicle safety screen valve mechanism can along with the closing of isolating switch, disconnect and automatically open, cover, so thoroughly can avoid the misoperation of staff, the personal safety of safeguard work personnel, has safe and reliable, flexible operation, the advantage such as easy to operate.
Upper described foundation embodiment is enlightenment, and by above-mentioned description, relevant staff in the scope not departing from this utility model thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its scope protected according to right.
