Abstract

Underwater straight line driving mechanism of the present invention comprises that electromagnet cavity and two guide rails, the electromagnet cavity internal fixation that are fixed on electromagnet cavity top have electromagnet array and the control circuit that is made of along guide rail direction linear array a plurality of electromagnet, each magnet spool links to each other with the output of control circuit, the input of control circuit stretches out outside the cavity, be equipped with permanent magnetic slider between two guide rails, the magnetic axis of electromagnet magnetic axis and permanent magnetic slider is vertical with guide rail respectively.When slide block was mobile in guide rail, water was squeezed in the slit of slide block and guide rail, formed hydrodynamic, made slide block keep not contacting with guide rail, thereby had reduced resistance.Because heavy moving parts is light, resistance is little, and is therefore very flexible, and vibrations are very little during motion.Fixed component is isolated with complete mechanical between the moving link, is easy to realize the sealing of cavity.Whole apparatus structure compactness, control is convenient, and can not cause any pollution to operational environment, can be widely used in doing straight-line mechanism under water.

Description

A kind of underwater straight line driving mechanism
Technical field
The present invention relates to a kind of underwater straight line driving mechanism, is to adopt electromagnetic force to drive specifically, and utilizes hydrodynamic to make moving component be suspended in straight line driving mechanism on the track.
Background technology
Adopt at present the straight line driving mechanism of Electromagnetic Drive,, be mostly in air ambient, to work as linear electric motors.And the straight line driving mechanism of realizing by mechanical transmission method combining, its structure more complicated, vibrations are also bigger during work.Because it is the resistance ratios air of water is a lot of greatly, and will consider the requirement of water resistance, therefore, necessary for realizing that underwater operation designs a kind of straight line driving mechanism that is used for underwater operation.
Summary of the invention
The purpose of this invention is to provide a kind of straight-line underwater straight line driving mechanism that is easy in water, realize easily.
Underwater straight line driving mechanism of the present invention comprises that electromagnet cavity and two guide rails, the electromagnet cavity internal fixation that are fixed on electromagnet cavity top have electromagnet array and the control circuit that is made of along guide rail direction linear array a plurality of electromagnet, each magnet spool links to each other with the output of control circuit, the underwater electrical connector of the input of control circuit through being installed in cavity stretches out outside the cavity, the electromagnet magnetic axis is vertical with guide rail, be equipped with permanent magnetic slider between two guide rails, the magnetic axis of permanent magnetic slider is also vertical with guide rail.
Underwater straight line driving mechanism of the present invention, because the magnetic axis of electromagnet magnetic axis and permanent magnetic slider is all vertical with guide rail, polarity by control circuit control electromagnet, make the electromagnetism iron phase of permanent magnetic slider and current location repel, and attract, thereby make permanent magnetic slider move to the target location from current location with the electromagnetism iron phase of target location.Continuous this process, just can make permanent magnetic slider in guide rail with the certain rule moving linearly, the realization linear drives.
The guide rail two ends can be uncovered, also can install additional to prevent that permanent magnetic slider from skidding off the barrier sheet of guide rail.
Frictional resistance when moving for reducing permanent magnetic slider can adopt the permanent magnetic slider that is the shuttle type.Further can adopt the permanent magnetic slider of forming by permanent magnet and the nylon block that is fixed on the permanent magnet two ends.
Underwater straight line driving mechanism of the present invention, when slide block was mobile in guide rail, water was squeezed in the slit of slide block and guide rail, formed hydrodynamic, made slide block keep not contacting with guide rail, thereby had reduced resistance.Because heavy moving parts is light, resistance is little, and is therefore very flexible, and vibrations are very little during motion.Fixed component is isolated with complete mechanical between the moving link, is easy to realize the sealing of cavity.Whole apparatus structure compactness, control is convenient, and can not cause any pollution to operational environment, can be widely used in doing straight-line mechanism under water.
