Embodiment
As shown in Figure 1, the utility model is isolated up and down solid insulation ring main unit and is comprised con-rod only with adjustable link, one end of adjustable link is connected with the first connecting lever 4 on the mechanism output shaft 5, the second connecting lever 7 of the other end and vacuum interrupter 16 mechanical driving parts is connected by pin, end near the first connecting lever 4 on the con-rod only 1 is provided with screwed hole, one end of adjusting bolt 3 is threaded onto wherein, the other end is connected by pin 6 with the first connecting lever 4, and described adjusting nut 2 is spun on the adjusting bolt 3 and screws mutually with the end of con-rod only 1.The first connecting lever 4 and the second connecting lever 7 equal in length, gearratio is 1: 1, and the arrangement of mechanism and vacuum interrupter 16 mechanical driving parts is for arranging up and down, and this kind arrangement can reducing mechanism and the cumulative volume of mechanical driving part.When being in combined floodgate or gate-dividing state, the first connecting lever 4, the second connecting lever 7 equate with the corner dimension of horizontal direction, all be about 20 degree, this and mechanism's output shaft angle 40 degree are complementary, can realize the output of the range in the transmission process, the loss that the reducing mechanism output angle is unnecessary.Described the second connecting lever 7 links together by square shaft and the 3rd connecting lever 11, and the angle between second, third connecting lever is 90 degree.
As shown in Figure 2, the two end supports of square shaft 9 is on the bearing pedestal 10 of base plate 8, the 3rd connecting lever 11 links together by pin and driving shaft 13, driving shaft 13 links together by pin with an end of three-phase drive axle connecting lever 14, and described pin passes in the oblong slots that is fixed on behind driving shaft connecting lever 14 and the driving shaft 13 on the track frame 12.
As shown in Figure 3, driving shaft connecting lever 14 and the adjusting bolt above the insulated tension pole 15 link together by pin, adjusting bolt and insulated tension pole 15 is together locked by adjusting nut, insulated tension pole 15 with on the lever that is flexible coupling with vacuum interrupter 16 link together.When mechanism's output shaft 5 moves to position shown in Figure 1 clockwise, the first connecting lever 4 drives the second connecting lever 7 by adjustable link and clockwise rotates, the second connecting lever 7 drives the 3rd connecting lever 11 by square shaft 9 and clockwise rotates, thereby the 3rd connecting lever 11 can drive driving shaft 13 and move right, under the drive of driving shaft 13, driving shaft connecting lever 14 moves downward along the oblong slots on the track frame 12, and then whole insulated tension pole 15 is moved downward, thereby reaches the purpose that vacuum interrupter 16 closes a floodgate.
As shown in Figure 4, when mechanism's output shaft 5 was rotated counterclockwise this position, the first connecting lever 4 drove the second connecting lever 7 by adjustable link and is rotated counterclockwise.
As shown in Figure 5, the second connecting lever 7 is rotated counterclockwise by square shaft 9 drives the 3rd connecting lever 11.
As shown in Figure 6, the 3rd connecting lever 11 drives driving shafts 13 to left movement, and driving shaft connecting lever 14 moves upward in the oblong slots on the track frame 12 under the drive of driving shaft 13, whole insulated tension pole 15 is moved upward, thereby reach the purpose of vacuum interrupter 16 separating brakes.
When occurring in the inadequate or too much situation of the combined floodgate excess of stroke, just can solve this problem by the length that lengthens or shorten adjustable link, the length that the driving shaft 13 that do not need to dismantle is regulated insulated tension pole 15, so just reduced unnecessary unloading process, improved operating efficiency, and made the mechanical driving part of mechanism and vacuum interrupter 16 more obvious aspect the motion synchronism.
Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection range of the utility model claims.
