Embodiment Construction

[0016] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0017] This embodiment provides a suction adjustable electromagnet that can be used as a trigger and release component under large depth water, which can meet the requirements of a submarine for triggering and releasing components.

[0018] Such as figure 1 As shown, the large-depth suction adjustable electromagnet includes: a housing 1, a magnetic core shaft 2, a permanent magnet 3, an electromagnetic coil 5 and a magnetic ring 6. The whole adopts a revolving structure, that is, the housing 1 is a hollow cylindrical structure with one end open and one end closed. The shell 1 adopts a pressure-resistant shell, which is an important part of the electromagnet for water pressure resistance, water tightness, and magnetic isolation, and also provides assembly space for other parts. The magnetic core shaft 2 has a T-shaped structure, that is, a cylindrical structure ...

Abstract

The invention relates to an electromagnet with adjustable suction force, which has good electromagnetic compatibility performance, adjustable suction force, simple structure and good reusability. It includes: a shell and a magnetically permeable mandrel, a permanent magnet and an electromagnetic coil installed inside the shell. In the electromagnet, the magnetic permeability of the shell, the sealing end cover, the magnetic core and the magnetic ring are different, and they are all better than the air permeability, forming a composite magnetic circuit, which can make the magnetic field generated by the electromagnetic coil inside it , so as to efficiently utilize the magnetic field and reduce power consumption. When the electromagnetic coil is not energized, the external device is adsorbed by the permanent magnet; when the external device needs to be released, the electromagnetic coil is energized, and by adjusting the current size, the strength of the magnetic field generated by the electromagnetic coil is adjusted to achieve suction adjustment; by changing the direction of the current, it can be Change the direction of the magnetic field generated by the electromagnetic coil. The electromagnet is used as a triggering and releasing component with an adjustable suction force, which can meet the requirements of the submersible for triggering and releasing the component.

Description

Technical field [0001] The invention relates to an electromagnet, in particular to an electromagnet with adjustable suction, and belongs to the field of electromagnetic technology. Background technique [0002] With human demand for the development of marine resources, deep ocean search and rescue, seabed topography and geomorphology exploration, etc., the requirements for the ocean depth that the submarine can reach, the longer and longer navigation time requirements, and the more and more navigation search range Big. Regardless of the military and civilian fields, the requirements for key trigger and release components are more refined. Especially for large systems powered by batteries (lead-acid, lithium batteries, etc.), the release and triggering components are required to be sensitive and reliable in function, and the components can meet the requirements of electromagnetic compatibility (mainly for military systems), with a large depth of voltage resistance , Good sealing...
