Embodiment
The embodiment of three station isolation grounding switch spring operating mechanisms, as shown in figs. 1-7, comprises support and is located at the switching manipulation module on support.Switching manipulation module has two covers, is respectively isolator operation module and earthed switch operational module.
Support is provided with three spaces, in the present embodiment, support includes four supporting brackets, space is then surrounded by adjacent supporting bracket, four supporting brackets are defined as in order successively the first supporting bracket 11, second supporting bracket 12, the 3rd supporting bracket 13 and the 4th supporting bracket 14 herein, each supporting bracket is connected by parts such as back shaft 15 grade, about the concrete connected mode between supporting bracket, no longer describes in detail herein.
The structure of isolator operation module is identical with the structure of earthed switch operational module, therefore will highlight herein one of them-structure of isolator operation module.
Isolator operation module comprises importation, energy storage section, output and power section.
Importation comprises line shaft 16, in the present embodiment, line shaft 16 is also connected with operating axis 17, what operating axis 17 and line shaft 16 were parallel to each other is assemblied in the 3rd, 4th supporting bracket is connected by gear mechanism transmission, wherein on line shaft 16, spin-ended being equipped with inputs thumb wheel 18, be rotatably equipped with link 19, link 19 comprises two side plates that the axially spaced-apart along line shaft is arranged and the fixed axis be connected between biside plate, one of them fixed axis is formed and connects bearing pin 20, for realizing the connection between link 19 and energy storage section, input thumb wheel 18 is provided with a pair pusher dog 181, in the process used, pusher dog 181 can coordinate with the end being connected bearing pin to be stirred link and rotates with the axis making it moving mechanical axis 16, output comprises output shaft 21 and exports thumb wheel 22, and output shaft 21 is coaxial with line shaft 16, on output thumb wheel 22 interval be provided with a pair block 221, pusher dog 181 is for ordering about link rotation, and block 221 can coordinate with link orders about output shaft rotation.Line shaft, back shaft and connection bearing pin are parallel to each other.
The flexible guide rod that energy storage section comprises energy-stored spring 23 and is located in energy-stored spring 23, one end of flexible guide rod is connected with line shaft 16 by link 19, the other end is rotated by back shaft 15 and is assemblied on support, in the present embodiment, flexible guide rod is articulated and connected with link by above-mentioned connection bearing pin 20, specifically, the loop bar 25 that expansion link comprises core bar 24 and is enclosed within core bar 24, one end away from corresponding link of loop bar 25 be provided with jaw and by jaw and back shaft 15 hinged, core bar 24 away from back shaft one end by be connected bearing pin 20 and coordinate and be connected on link.Energy-stored spring 23 top is contained between link and back shaft.
Power section comprises the motor 26 be located on support, and motor 26 and operating axis are in transmission connection, thus can control the action of operating mechanism, about this point, also exist in prior art using motor as the operating mechanism driven, this technology is comparatively conventional, is therefore no longer described in detail.
When using this operating mechanism disconnecting switch operation to close a floodgate, first order about operating axis by motor to turn clockwise, the rotary motion of operating axis is passed to line shaft through gear mechanism, line shaft drives input thumb wheel synchronous axial system in the process of rotating, input the pusher dog on thumb wheel and then stir and connect bearing pin and drive link to rotate, and then order about energy-stored spring storage power, when link turns to the poor position of the axes normal of expansion link axis and line shaft, energy-stored spring accumulation of energy terminates, then fast release coordinated with the block on output thumb wheel by link and drive and export thumb wheel and rotate, export thumb wheel and then drive output shaft rotation to carry out disconnecting switch operation, the distance wherein inputted between two pusher dogs on thumb wheel meets the following conditions: link leaves the pusher dog originally stirring it in the moment released energy at energy-stored spring, after energy-stored spring release terminates, link just with another fingers contact, thus energy-stored spring can be avoided to release energy caused movement response on line shaft and operating axis, in like manner, the interval exported between two blocks on thumb wheel should meet the requirement not interfering link.In separating brake process, operating axis is rotated counterclockwise, and its process is identical with making process principle, and it will not go into details herein.
