Abstract
The utility model discloses a magnetic liquid performance display device, which compris magnetic liquid, a container, a permanent magnet and a connecting block. The permanent magnet (3) is connected with the connecting block (4) and a moving mechanism (5), and is directly hung above the container (2) filled with the magnetic liquid (1). With the movement of the moving mechanism (5) and the connecting block, the permanent magnet (3) is to-and-fro moved along the vertical direction or rotary moved in a vertical plane. The permanent magnet (3) adopts the rubidium-iron-boron material, and the connecting block (4) adopts the magnetic conductive material. The moving mechanism (5) adopts the crank-connecting rod structure to drive the connecting block (4) and the permanent magnet (3) to to-and-fro move along the vertical direction. Or a worm gear-worm rod structure is adopted to drive the connecting block (4) and the permanent magnet (3) to rotary move in the vertical plane. The device can vividly demonstrate the surface instability of the magnetic liquid and enlighten the people to exploit the unknown field of the high-technology industry.
Description
Technical field
The utility model belongs to magnetic liquid performance exhibiting device, and the showpiece that is specially adapted to places such as science and technology center, universities and colleges, middle and primary schools is showed.
Background technology
The present magnetic liquid performance display device liquid climbing device etc. that is magnetic in the science and technology center, these install ubiquitous problem: separated by chamber wall between the electromagnet of generation magnetic source or permanent magnet and the magnetic liquid, between the two apart from bigger, magnetic liquid can only move up and down along chamber wall, the magnetic liquid surface can not dynamic change, the surface instability that can not show magnetic liquid visually.
Summary of the invention
Technical problem to be solved in the utility model is that in the existing magnetic liquid performance display device, the distance between magnetic liquid and the magnetic source is bigger, can not show the surface instability of magnetic liquid visually, therefore, provides a kind of magnetic liquid performance display device.
The technical solution of the utility model: permanent magnet links to each other with motion with contiguous block, directly is suspended in the top of the container of splendid attire magnetic liquid.Motion by motion and contiguous block, permanent magnet is reciprocating in vertical direction or rotate in vertical plane, attract the magnetic liquid surface in the container periodic instability to occur, that is: under the to-and-fro movement mode, the magnetic liquid surface along with permanent magnet and magnetic liquid surface spacing from different, the spinule of differing heights appears.Under rotary movement, the magnetic liquid surface spinule occurs periodically along with the anglec of rotation difference of permanent magnet on the diverse location of same circumference.
Motion can adopt crank one bar linkage structure, and it is reciprocating in vertical direction to drive contiguous block and permanent magnet; Also can adopt the worm gear-endless screw structure, drive contiguous block and permanent magnet and in vertical plane, rotate.
The beneficial effects of the utility model are that this device can be demonstrated the surface instability of magnetic liquid visually, inspires people to explore high-tech tera incognita.
Description of drawings
Fig. 1 magnetic liquid performance display device structure synoptic diagram.
Among the figure: magnetic liquid 1, container 2, permanent magnet 3, contiguous block 4, motion 5.
Embodiment
With the accompanying drawing is that the utility model is described in further detail for embodiment:
Permanent magnet 3 links to each other with motion 5 with contiguous block 4, directly is suspended in the top of the container 2 of splendid attire magnetic liquid 1.Motion by motion 5 and contiguous block 4, permanent magnet 3 is reciprocating in vertical direction or rotate in vertical plane, attract magnetic liquid 1 surface in the container 2 periodic instability to occur, that is: under the to-and-fro movement mode, magnetic liquid 1 surface along with permanent magnet 3 and magnetic liquid 1 surface spacing from different, the spinule of differing heights appears.Under rotary movement, magnetic liquid 1 surface spinule occurs periodically along with the anglec of rotation difference of permanent magnet 3 on the diverse location of same circumference.
The Rb-Fe-B material of the material selection function admirable of permanent magnet 3, because the magnetic field intensity height that rubidium iron boron produces, magnetic liquid surface wild effect is obvious.
The shape of permanent magnet 3 can be a piece shape or cylindrical.
Container 1 is an open-top receptacle, and shape is not limit, but the ratio of height and the characteristic length of bottom is less than 1.
For the ease of the surperficial situation of change of observation magnetic liquid, container 1 is selected material transparent for use, as organic glass or other glass material.
Use-case one:
Select the magnetic liquid of keryl for use, diameter is that the cylindrical magnet iron of 50mm adopts Rb-Fe-B material, and the height of circle tube glass container is 100mm, and interior diameter is 150mm.Container 1 is selected organic glass for use.Reciprocating in vertical direction with crank-bar linkage structure drive contiguous block and permanent magnet.In the container magnetic liquid along with permanent magnet and magnetic liquid surface spacing from different, the spinule of differing heights appears, the demonstration effect is very obvious.
Use-case two:
Select water base magnetic liquid for use, diameter is that the cylindrical magnet iron of 50mm adopts Rb-Fe-B material, and the height of circle tube glass container is 150mm, and interior diameter is 300mm.Container 1 is selected organic glass for use.Rotate in vertical plane with worm gear-endless screw structure drive contiguous block and permanent magnet, the magnetic liquid surface spinule occurs periodically along with the anglec of rotation difference of permanent magnet on the diverse location of same circumference, and the demonstration effect is also very obvious.
