Deng.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of embodiment one.
Fig. 2 is the structural schematic diagram of embodiment two.
Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention will be further explained.
Embodiment one: such as Fig. 1.
Energization solenoid 2 is set on ground 1, and the contour line of section of the energization solenoid 2 along central axis meets
Analytic expression y=36/x2.The magnetic flux of the known 2 each cross section in inside of energization solenoid is equal in physics, and magnetic induction line is transversal
EDS maps are uniform.By analytic expression y=36/x2It is found that y's and x square is inversely proportional, that is, the cross section of y and energization solenoid 2
Area is inversely proportional.
After energization solenoid 2 is passed through constant dc, magnetic induction is equal to B=Φ/S；Φ magnetic flux in formula, in energization spiral shell
2 inner, constant of spool；S is the cross-sectional area of energization solenoid 2.So B and y are directly proportional, that is, B with height raising at
The increase of ratio.
Imagine a rotatable magnetic ball in above-mentioned magnetic field, the induced magnetic field of magnetic ball is similar to earth's magnetic field
Magnetic induction line direction is directed toward in shape, the pole N always；Since the magnetic induction line direction inside energization solenoid 2 is bordering on vertically, magnetic ball
Difference in height approximately constant locating for the two poles of the earth, the difference (namely bead be integrally subject to magnetic field force) for the magnetic field force that the two poles of the earth are subject to is also
Approximately constant has also obtained a kind of agravic or low gravitation as long as guaranteeing that magnetic field force that bead is subject to and gravity are equivalent, reversed
Environment.
It should be pointed out that magnetic field force is along magnetic induction line direction, and the magnetic induction line in figure inside energization solenoid 2 is not tight
(magnetic induction line on central axis is along the vertical direction) along the vertical direction of lattice.Therefore actually trainer is in energization solenoid 2
Inside also suffers from the horizontal component of the magnetic field force of a direction central axis.It, can be with but by the shape of design spiral pipe
Guarantee that the horizontal component of magnetic field force is much smaller than vertical component.And the shadow that air extractor 3 further weakens horizontal component can be set
Ring, although air extractor 3 generate horizontal suction not exactly equal to the horizontal component of magnetic field force, both in energization spiral shell
It is 0 at the central axis of spool 2, it, can be further in 2 edge of energization solenoid maximum, therefore by being reasonably evacuated intensity
Reduce the influence of magnetic field force horizontal component.In fact, most importantly balancing gravity, a less big level are divided for weightless flight
Its influence of power is limited.And this horizontal component, closer to 2 central axis of energization solenoid with regard to smaller, until being 0.
Two layers of the air extractor is apart from for 30cm -1m.Air extractor 3 includes air extractor automatic control unit；Automatically
Trainer's height is detected, the air extractor of the height is opened, closes other layer of air extractor；Or it only opens near trainer
Air extractor.
The magnetic devices are rotatable magnetic spheres or magnetic liquid or iron powder.
Magnetic masking layer is set between the magnetic devices and human body.
Magnetic masking layer is also provided between each magnetic devices.
Safety pad is set on ground or safety net is set below energization solenoid 2.
In the present embodiment, in the range of 4m < y < 9m, for being trained and testing.
Embodiment two: if the difference of Fig. 2 and embodiment one are, the section of 2 pipe of energization helical along central axis
Contour line meets y=54/x2.In the present embodiment, in the range of 6m < y < 13.5m, for being trained and testing.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art within the technical scope of the present disclosure, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
