Abstract
The utility model relates to a space-time orbit display and recording instrument for moving objects, which comprises an experimental box body and a movement object which can move in the experimental box body. The utility model is characterized in that the inner wall of a baffle plate which forms a movement cavity of the movement object is provided with a magnetic display board. A cycle high-change magnetic field generator is arranged in the movement object. The magnetic material of the magnetic display board can be absorbed on the inner wall of the display board in the course of the movement object under the action of the high-change magnetic field generator, and a two-dimensional space space-time orbit line along the variation of time cycle is formed. The utility model has the advantages of high safety, simple operation and vivid imaged and visual experiment, and has stronger persuasion.
Description
The utility model relates to a kind of teaching and experiment equipment, particularly a kind of moving object space-time track display recorder.
At present, in middle school physics and teaching analytical geometry, though adopt magic lantern, film, computer to wait and show that object is simple and easy to do in the two-dimensional space motion state, but because this kind mode is to give artificial earlier the setting, so cogency is not strong, simultaneously, also can't intuitively the Space Time track be shown truly simultaneously.A kind of corona latent image formula movement locus instrument was once arranged, its structure comprises experiment casing and the moving object that can move in the experiment casing, the experiment casing is by pedestal and be arranged in parallel aluminium sheet and copper mesh on pedestal, constitutes attached to the paraffin paper on the copper mesh inwall, and the moving object employing is a steel ball, during use, it needs to apply the high voltage more than the 2500V between aluminium sheet and copper mesh, when steel ball moves in the discharge cavity of aluminium sheet and copper mesh composition, place, steel ball place will cause minimum space, thereby the formation highfield produces effluve.And the localized hyperthermia of discharge generation can make the wax on this place's paraffin paper melt and polarization, and wax solidifies the after-polarization electric charge to be preserved, and forms electrostatic latent image.After this, by contrasting power electrostatic latent image is developed again, finally show the movement locus of object.This movement locus instrument is because each experiment all needs the paraffin paper that renews and carries out development operation, so both caused waste, operation also comparatively bothers, and the high voltage of 2500V also is absolutely unsafe during operation.Simultaneously, also can't be synchronously during demonstration intuitively the Space Time track of moving object be directly manifested, and the track that the demonstration back shows by development is comparatively tiny, also is not easy to observation of students.
The purpose of this utility model is to provide a kind of moving object space-time track display recorder, it is safe in utilization, easy and simple to handle, it both can be visual in image shows the space-time track in the object of which movement process synchronously truly, the space-time track of whole moving object can be carried out record again.
Its concrete solution is: the wherein inwall of a baffle plate that constitutes moving object campaign cavity in the experiment casing is provided with one and is evenly equipped with the magnetic display board that contains magnetic material loculus body on it, and be provided with the one-period alternating magnetic field generator in the moving object, moving object can be adsorbed on the magnetic material of institute in the little cavity of part magnetic display board on the display board inwall display surface with the variation of magnetic field power in motion process to some extent under its effect, thereby constitutes a two-dimensional space Space Time trajectory of cycle variation in time.
In addition then, described cycle alternating magnetic field generator is by oscillation signal generator, the field coil that is connected with the oscillation signal generator output terminal and iron core constitutes or be made of the field coil and the iron core that are connected with outside alternating source.
Moreover a wherein baffle plate that constitutes moving object campaign cavity in the experiment casing is the transparent body, is beneficial to the student and observes intuitively.
The utility model utilizes the cycle alternating magnetic field generator that is provided with in the moving object to make and shows the track trace that moving object is the variation same period in time on the magnetic display board, make it safe in utilization, easy and simple to handle, and can be lively, image, intuitively show truly synchronously and write down vertically, the flat throwing, the rectilinear motion of inclined throw movements object, the motion state of curvilinear motion and track, by this experiment with stronger cogency and when short the chien shih student obtain the physical knowledge correctly consolidated, the utility model is real in a kind of desirable at education experiment with the moving object space-time track display recorder of promoting the use of in studying.
In conjunction with the accompanying drawings the utility model is described in detail below by embodiment:
Fig. 1 is the structural front view of the utility model embodiment 1 experiment casing.
Fig. 2 is the structure side view of Fig. 1.
Fig. 3 is the structural front view of the utility model embodiment 1 moving object.
Fig. 4 is the side view of Fig. 3.
Fig. 5 is the structural front view of embodiment 2 moving objects.
Embodiment 1:
Among Fig. 1, Fig. 2, framework 2 is fixedly connected on the pedestal 5, baffle plate 7 adopts be one its be provided with the clear glass baffle plate of handle 8, it with the corresponding respectively inserting groove that is plugged on the upper and lower position of framework of baffle plate 3 in, thereby constitute the motion cavity of moving object by framework 2 and two plate washers 7,3, be bonded with a magnetic display board 9 on the inwall of baffle plate 3, and be densely covered with the honeycomb cavity on this magnetic display board 9, be provided with powdered magnetic material in the cavity.In addition then, the framework that constitutes the motion cavity wall is provided with the emission moving object that is used to peg graft and executes the jack 6,10 that actuation mechanism is launched bar, and the top of framework is equipped with level meter 1.
Housing 11 in Fig. 3, Fig. 4 moving object is a column type housing, the field coil 12 of the cycle alternating magnetic field generator that is provided with in it is positioned at the middle part of housing, and, the two ends that are arranged on the iron core 13 in the field coil place the outside of housing, and oscillation signal generator 14 also is arranged in the housing 11.
During use, should at first adjust its levelness by the adjustment screw on the pedestal 54, open alternating magnetic field generator operating switch 15, according to the flat difference of throwing, vertically fall, tiltedly throwing desired location of do experiment, the top or the bottom that actuation mechanism is arranged on cavity of executing that clamping can be had moving object, utilization is inserted in the jack 6 or the emission bar in the jack 10 is launched, and simultaneously, also baffle plate 7,3 should be pegged graft.When moving object is moved in cavity, because the electric signal of oscillation signal generator output can make the magnetic field generating period at place, iron core 13 two ends change under the effect of field coil, with the magnetic material in part magnetic display board 9 place's cavitys change with the power in magnetic field and be adsorbed on to some extent on the display surface of magnetic sheet, thereby constitute a two-dimensional space Space Time trajectory of rule alternate in time.Treat to utilize after the experimental observation end of record (EOR) magnetic erase to wipe movement locus line on the cancellation display surface.
Embodiment 2:
Cycle alternating magnetic field generator in the present embodiment moving object only is made of field coil 16 and iron core 17.During work, field coil 16 is electrically connected with the city of 220V, 50HZ by lead 18, and all the other structures and the course of work are identical with embodiment 1.
