Fig. 2 is that the utility model is applied in the structural representation in high voltage switchgear.
Wherein 1 is supporting bracket, and 2 is rotating shaft, and 3 is closing by hand driving spring, and 4 is spring guide, and 5 is pin, 6 is compression connecting lever, and 7 is spacer pin, and 8 is actuating axle, and 9 for driving connecting lever, 10 is spring stop, and 11 is closing by hand device, and 12 is drive link, and 13 is permanent magnet mechanism.
Embodiment
For above-mentioned purpose of the present utility model, feature and advantage can more be become apparent, below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
Set forth detail in the following description so that fully understand the utility model.But the utility model can be different from alternate manner described here and implements with multiple, and those skilled in the art can do similar popularization without prejudice to the utility model intension in the situation that.Therefore the utility model is not subject to the restriction of following public embodiment.
Referring to Fig. 1 and Fig. 2, closing by hand device 11, comprises supporting bracket 1, is respectively arranged with spring energy agency and combined floodgate crank arm mechanism in supporting bracket 1; Spring energy agency includes rotating shaft 2, spring stop 10, spring guide 4 and closing by hand driving spring 3; In supporting bracket 1, be provided with rotating shaft 2, one side of spring stop 10 is connected with rotating shaft 2, the opposite side of spring stop 10 is connected with one end of spring guide 4 with closing by hand driving spring 3 respectively, the other end of spring guide 4 offers cotter way, and spring guide 4 is arranged on the inside of closing by hand driving spring 3; Combined floodgate crank arm mechanism includes compression connecting lever 6, drives connecting lever 9 and actuating axle 8, and one end of compression connecting lever 6 is slidably connected with spring guide 4 by the pin 5 being arranged in cotter way; The other end of compression connecting lever 6 is connected with driving one end of connecting lever 9 by actuating axle 8, drives the other end of connecting lever 9 to be fixed in supporting bracket 1; In supporting bracket 1, be also provided with spacer pin 7, spacer pin 7 is positioned at the right-hand of the compression top of connecting lever 6 and spring guide 4; Closing by hand device 11 can be arranged on the inside of the high voltage switchgear that includes permanent magnet mechanism 13, and closing by hand device 11 is independent each other with permanent magnet mechanism 13.
While carrying out closing by hand, first clockwise rotate actuating axle 8, the rotation of actuating axle 8 has driven clockwise rotating of spring energy agency integral body, and the rotation of spring energy agency mainly relies on rotating shaft 2 to realize; And now compress connecting lever 6 for rotating counterclockwise, spring energy agency and compression connecting lever 6 are because direction of rotation is inconsistent, pin 5 direction along rotating shaft 2 in cotter way is slided, closing by hand driving spring 3 is compressed, thereby realize energy storage, for ensuing closing by hand performs energy, preparing, there is not skew in spring guide 4 while guaranteeing 3 compression of closing by hand driving spring; When clockwise rotating actuating axle 8 to maximum rotation angle, start to rotate counterclockwise actuating axle 8, because the center line of now rotating shaft 2, spring guide 4, compression connecting lever 6 and actuating axle 8 is close to forming straight line, so closing by hand driving spring 3 keeps compressed state; When the center line of rotating shaft 2, spring guide 4, compression connecting lever 6 and actuating axle 8 forms straight line, closing by hand driving spring 3 is in maximum compressibility, when rotation after this straight line, the energy that closing by hand driving spring 3 stores starts to discharge, and drive actuating axle 8 to rotate counterclockwise, now drive connecting lever 9 also for rotating counterclockwise; In aforesaid operations process, spacer pin 7 crank arm mechanism of can guaranteeing to close a floodgate is moved in limited scope; The release of closing by hand driving spring 3 energy makes rotating shaft 2 obtain a speed, this also makes to drive connecting lever 9 to obtain kinetic energy, drive connecting lever 9 to rotate with speed, after turning to certain position, drive connecting lever 9 ram drive rollers, driven roller can ram drive connecting rod 12 makes it to the switching-on mechanism direction rectilinear motion in high voltage switchgear, finally realizes the closing function of high voltage switchgear.
After combined floodgate completes, rotate counterclockwise actuating axle 8, carry out reset operation, allow closing by hand driving spring 3 in energy storage state simultaneously, to prepare closing by hand next time.
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not within departing from spirit and scope of the present utility model; can utilize method and the technology contents of above-mentioned announcement to make possible change and modification to technical solutions of the utility model; therefore; every content that does not depart from technical solutions of the utility model; any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all belong to the protection range of technical solutions of the utility model.
