The utility model has the advantages that: iron core and the excitation coil work of moving is in a fully enclosed environment (being the enclosure space) to great reduction the mechanism's combined floodgate trouble that causes because of environmental factor.
Description
Technical field
This utility model relates to the technical field of electromagnetic operating mechanism, particularly relates to a kind of simple in construction, failure rate is low, electromagnetic operating mechanism applied widely.
Background technology
Electromagnetic operating mechanism is a kind of main operating mechanism closed a floodgate as catalyst, and great majority still adopt traditional clapper-type electromagnetic mechanism, and are open wide exposed form.Traditional operating mechanism includes the parts such as rotating shaft 7, armature 8, iron core 9, yoke 10 and solenoid 11, but vacuum contactor field use in be disadvantageous in that: a, in traditional mechanism running environment if any the foreign material that can be magnetized time, the process of mechanism's normal operation there will be the foreign material being magnetized and be inhaled into mechanism, thus causing that mechanism's work not in place burns out solenoid, even can close a floodgate the phenomenon that line fault occurs not in place because of catalyst.B, employing Direct Action Type design, compare traditional clapper-type mechanism and use wider, particularly in vacuum contactor field, adopt Direct Action Type operation more to can ensure that and close the steady of contact, eliminate the contact of incline plane of switch contact, reduce switch contact and close the generation of the fault such as timesharing arcing and adhesion phenomenon.
For this, designer of the present utility model is because drawbacks described above, and by summing up research and design, comprehensive experience and the achievement being engaged in related industry for a long time for many years, research design goes out a kind of unicoil electromagnetic operating mechanism, to overcome drawbacks described above.
Summary of the invention
This utility model to solve the problem that actual motion is unstable and fault rate is higher being to improve traditional mechanism, makes electromagnetic mechanism adapt to environment wider, extends probe of contactor service life, thus the rate of breakdown reduced in vacuum contactor actual motion at the scene.
The technical solution of the utility model is: a kind of totally-enclosed electromagnetic operating mechanism of unicoil, and including cylinder, yoke, dynamic iron core, upper cover, lower cover and magnet exciting coil, described upper cover and lower cover are separately mounted to the two ends of cylinder, collectively constitute one with cylinder and close space；Described yoke, dynamic iron core and magnet exciting coil are assemblied in described closing space；Peripheral equipment at dynamic iron core is furnished with yoke and magnet exciting coil, and this magnet exciting coil is close to described upper cover, and yoke is close to described lower cover, and described dynamic iron core is moved in closing space by detent mechanism；Described upper cover adopts permeability magnetic material to be made；Lower cover adopts non-magnet material to be made.
The structure of described detent mechanism particularly as follows: be provided with the first cylindrical portion passing lower cover in one end of dynamic iron core, and the other end is provided with the second extension passing upper cover, offers connecting hole on the second described extension.
The utility model has the advantages that: dynamic iron core and magnet exciting coil are operated in a totally enclosed environment (namely closing space), thus mechanism Closing fault because environmental factors cause is greatly reduced.

Detailed description of the invention
Further describe this utility model below in conjunction with specific embodiment, advantage of the present utility model and feature will be with describe and apparent.But these embodiments are only exemplary, scope of the present utility model is not constituted any restriction.It will be understood by those skilled in the art that and the details of technical solutions of the utility model and form can be modified or replace under not necessarily departing from spirit and scope of the present utility model, but these amendments and replacement each fall within protection domain of the present utility model.
Referring to Fig. 1 and Fig. 2, this utility model relates to a kind of totally-enclosed electromagnetic operating mechanism of unicoil, including cylinder 1, yoke 2, dynamic iron core 3, upper cover 4, lower cover 5 and magnet exciting coil 6, described upper cover 4 and lower cover 5 are separately mounted to the two ends of cylinder 1, collectively constitute one with cylinder 1 and close space；Described yoke 2, dynamic iron core 3 and magnet exciting coil 6 are assemblied in described closing space；Peripheral equipment at dynamic iron core 3 is furnished with yoke 2 and magnet exciting coil 6, and this magnet exciting coil 6 is close to described upper cover 4, and yoke 2 is close to described lower cover 5, and described dynamic iron core 3 is moved in closing space by detent mechanism；Described upper cover 4 adopts permeability magnetic material to be made；Lower cover 5 adopts non-magnet material to be made.Described magnet exciting coil is the driving power source of iron core；Described yoke is as the main element of magnetic conductive loop；Described lower cover is as fixing and support guide effect, and not as magnetic conductive part, selection material is non-magnet material.
The structure of described detent mechanism particularly as follows: be provided with the first cylindrical portion passing lower cover 5 in one end of dynamic iron core 3, and the other end is provided with the second cylindrical portion passing upper cover 4, offers connecting hole on the second described cylindrical portion.First cylindrical portion is used as central axis positioning action when dynamic iron core 3 moves；Second cylindrical portion is used as central axis positioning action when dynamic iron core 3 moves and operating mechanism and the interconnection function by actuating parts.
Operation principle of the present utility model is: can produce magnetic field when magnet exciting coil 6 is energized, and by magnetizing magnetic conductor around, can produce different magnetic poles at upper cover 4 and dynamic iron core 3.According to, under the active force that different magnetic poles attracts each other, driving dynamic iron core 3 to the motion of upper cover 4 direction adhesive, when magnet exciting coil 6 continues to be energized, the magnetic field of generation constitutes magnetic loop at cylinder 1, yoke 2, dynamic iron core 3 and upper cover 4, thus keeping "on" position.
The magnetic force that described dynamic iron core 3 is produced by the outside external force (counter-force) by actuating parts and magnet exciting coil 6 moves in cylinder 1, and is maintained at corresponding location status.
