Description
Technical field
The present invention relates to physical teaching aid field, especially, it is related to a kind of Mechanical Longitudinal Waves apparatus for demonstrating.
Background technology
In physics teaching field, in order to deepen understanding of the student for physical phenomenon, it usually needs carry out phenomenon demonstration；Its
In, it is typically more vivid for shear wave phenomenon in kymatology；Such as, by the continuous traversing as shear wave of common sine wave；So
And, for compressional wave, due to that cannot be described with ready-made geometry lines, therefore it is relatively difficult to the imagination；Therefore, generally need by
Turn long is demonstrated, but because compressional wave is when by turn long, only cause turn it is local produce it is smaller vertical
To compression or stretching, and speed, visually to observe that this kind of phenomenon is more difficult.
The content of the invention
Regarding to the issue above, it is an object of the invention to provide a kind of photo-electric Mechanical Longitudinal Waves apparatus for demonstrating, demonstration dress
Put clearly visually can carry out outdoor scene demonstration by Mechanical Longitudinal Waves phenomenon, so as to deepen understanding of the student for Mechanical Longitudinal Waves, carry
Quality of instruction high.
The technical solution adopted for the present invention to solve the technical problems is：The photo-electric Mechanical Longitudinal Waves apparatus for demonstrating includes perpendicular
The straight arch turn for arching upward upwards；The arch turn by bend to helix can deformation fillet constitute；Along described
Fillet is extended with LED light bar, and being equally spaced in the LED light bar has where LED wafer parallel with one another, and each LED wafer
Parallel branch in be serially connected with vibroswitch, the parallel branch where the vibroswitch only makes itself when vibrated connects
It is logical；One end of the arch turn is fixed on fixed pedestal, and the power supply knot of the LED light bar is provided with the fixed pedestal
Structure；The other end of the arch turn is fixed on a movable slider moving up and down；The movable slider is located at behaviour
Make in pedestal, the operating assembly that can move up and down the movable slider is provided with the operation pedestal.
Preferably, the LED light bar is patch-type LED light bar, its base bar composition is described can deformation fillet；And narrow
One layer of fluorescence thin layer for covering each LED wafer is laid in the front of bar, makes to be spread around the light photograph that each LED wafer produces, with
The arch turn is partially formed a bit of soft light.
Preferably, including the vertical slideway slided up and down for the movable slider in the operation pedestal；The behaviour
Making component includes the vertical handle being fixed on the movable slider, and is supported between movable slider and vertical slideway vertically
Back-moving spring；The vertical handle stretches out the operation pedestal, can by vertical shift the vertical handle, realize the activity
The vertical shift of sliding block；And gap coordinates between the movable slider and the vertical slideway, without vertical friction, so that described
Back-moving spring can make the movable slider Rapid reset after movement.
The beneficial effects of the present invention are：The photo-electric Mechanical Longitudinal Waves apparatus for demonstrating when in use, only need to be by the behaviour
Make the vertically movable suitable distance of the movable slider as component, then movable slider is resetted；Then movable slider is in the arch
A compressional wave is formed in shape turn, the compressional wave will back and forth vibrate transmission between the two of arch turn ends, until ripple
Energy is damped and exhausts；In the process, the vibroswitch inside the LED light bar is connected when compressional wave arrives, and vertical
Ripple disconnects after leaving so that the luminous site of the arch turn follows compressional wave to swing back and forth, so as to represent compressional wave and must drench
Most cause is drenched, to deepen the understanding of the compressional wave of student, is improved the quality of teaching.
Brief description of the drawings
Fig. 1 is the structural representation of this photo-electric Mechanical Longitudinal Waves apparatus for demonstrating one embodiment.
Fig. 2 is the partial schematic diagram of the arch turn of this photo-electric Mechanical Longitudinal Waves apparatus for demonstrating.
Fig. 3 is the electrical structure schematic diagram of this photo-electric Mechanical Longitudinal Waves apparatus for demonstrating.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples：
In the embodiment shown in fig. 1, the photo-electric Mechanical Longitudinal Waves apparatus for demonstrating includes the arch turn for arching upward straight up
1；The arch turn 1 by bend to helix can deformation fillet constitute；LED light bar is extended with along the fillet；
In the present embodiment, as shown in Fig. 2 the LED light bar is patch-type LED light bar, its base bar 11 constitute it is described can deformation fillet；And
And one layer of fluorescence thin layer 13 for covering each LED wafer D is laid in the front of fillet, make the light photograph surrounding that each LED wafer D is produced
Diffusion, i.e. the brightness at LED wafer D is maximum and gradually dim to the LED wafer both sides from LED wafer D centers, with institute
That states arch turn 1 is partially formed a bit of soft light.
The electrical structure of the LED light bar is as shown in figure 3, its two electricity extending along the fillet of the arch turn
Source main line is directly connected to power supply architecture U；The LED wafer D for being equally spaced parallel with one another is included between two power supply main lines, and
Vibroswitch K, the vibroswitch K are serially connected with parallel branch where each LED wafer D only makes itself institute when vibrated
Parallel branch connect；The LED wafer D in each region in i.e. described arch turn 1, lights only during compressional wave passes through.
Above-mentioned Mechanical Longitudinal Waves apparatus for demonstrating, one end of the arch turn 1 is fixed on fixed pedestal 2, and this is solid
Determine the interior power supply architecture U for being provided with the LED light bar of pedestal 2；The other end of the arch turn 1 be fixed on one can on move down
On dynamic movable slider 31；In operation pedestal 3, being provided with the operation pedestal 3 can make the activity to the movable slider 31
The operating assembly that sliding block 31 is moved up and down；Specifically, included in the operation pedestal 3 and slided up and down for the movable slider 31
Vertical slideway, and gap coordinates between the vertical slideway and movable slider 31, without obvious vertical friction；The operating assembly
Including being fixed on vertical handle 32 on the movable slider 31, extending downwardly from operating pedestal 3, and activity is supported on vertically
Back-moving spring 33 between sliding block 31 and vertical slideway；By vertical drop-down vertical handle 32, make the movable slider 31
Displacement straight down, then decontrols the vertical handle 32, then in the presence of the back-moving spring 33, movable slider 31 is quick
Reset upwards, to form a compressional wave in the arch turn 1.
When in use, the Mechanical Longitudinal Waves formed by the movable slider 31 are encircleing above-mentioned photo-electric Mechanical Longitudinal Waves apparatus for demonstrating
Vibration transmission back and forth between two ends of shape turn 1, until Wave energy is damped exhausting；In the process, the LED
Vibroswitch K inside lamp bar is connected when compressional wave arrives, and is disconnected after compressional wave leaves so that the arch turn 1
Luminous site follows compressional wave to swing back and forth, and so as to represent incisively and vividly compressional wave, to deepen the understanding of the compressional wave of student, improves
Quality of instruction.
