Abstract

The utility model relates to a bell electro-magnet structure for a ship and solves a technical problem which is to overcome the problems such as insufficient suction, poor iron core movement flexibility and heating coil of the prior bell electro-magnet. The utility model improves the suction of the electro-magnet and the iron core movement flexibility, and provides a bell electro-magnet structure for a ship which is suitable for long-time use. The utility model has a coil, a front guiding sleeve is arranged in the coil, an iron core is positioned in the front guiding sleeve, the iron core is provided with a spring, a moving-strip is positioned on the rear end of the iron core, and the moving-strip is engaged with a static strip through a contact point. The special point is that the coil is mounted on a supporting frame, a back guiding sleeve which is made of non-ferromagnetic material is positioned on the rear end of the iron core, and the spring is in a tower shape. The coil of the utility model is completely uncovered, thereby having good heat emission performance and being capable of long-time continuous work. The back guiding sleeve is made of non-ferromagnetic material, thereby eliminating the interference of the electromagnetic force of the rear end of the iron core and improving the suction of the electro-magnet. The spring employs a tower shape, thereby eliminating the friction force between each spring coil and improves the iron core movement flexibility.

Description

The electric bell electromagnet structure

Technical field

The utility model belongs to a kind of electromagnet apparatus, particularly a kind of naval vessel electric bell electromagnet structure.

Background technology

Electric bell is used very extensive in various naval vessels, is indispensable equipment in the naval vessel.It mainly is made up of bell lid, fixed support and electromagnet.Electromagnet is made up of sleeve, coil, front and back guide pin bushing, iron core, spring, moving plate, still, electric capacity and capacitance bracket etc.Wherein, coil is installed in the sleeve, is in full closeding state, thereby the heat that coil produces when work can not in time come out, and has caused coil heating, and coil can not be worked for a long time; Preceding guide pin bushing adopts nonmagnetic substance to make, and back guide pin bushing adopts ferrimagnet to make, behind coil electricity, the electromagnetic force that produces on the back guide pin bushing has a suction to iron core, this suction plays the reduction effect to the electromagnetic force that iron core produces, and makes the suction deficiency of electromagnet, hinders iron core and travels forward; In addition, volute spring is a tubulose, and the friction between each circle is bigger, and electromagnetic force is also played the reduction effect, and influences the dirigibility of iron core action; The problems referred to above have caused the electromagnet reduction of property indexes, and then have influenced the normal use of electric bell.

Summary of the invention

The technical problems to be solved in the utility model is, overcome problems such as existing naval vessel is poor with electric bell electromagnet suction deficiency, iron core dexterity of action, coil heating, improve the suction of electromagnet and the dirigibility of iron core action, a kind of long-time naval vessel electric bell electromagnet structure that uses that is fit to is provided.

The utility model has a coil, preceding guide pin bushing is housed in coil, in preceding guide pin bushing, iron core is housed, spring is housed on the iron core, in the rear end of iron core moving plate is housed, moving plate matches with still by the contact, its special character is, described coil is rack-mount, and the back guide pin bushing of making of nonferromugnetic material is housed in the rear end of iron core, and spring is the turriform spring.

Coil of the present utility model is rack-mount, and coil is all exposed in air, has improved the radiating condition of coil, and the heat that produces on the coil can distribute timely, thereby, coil continuous working for a long time; Back guide pin bushing is made of nonferromugnetic material, has eliminated the interference of iron core rear end electromagnetic force, thereby has improved the suction of electromagnet; Spring adopts the turriform spring that an end is big, an end is little, has eliminated the friction between each circle of spring, has improved the dirigibility of iron core action, thereby has improved the combination property of electromagnet.
