Favorably.It is suitable for being used as demonstration apparatus for energy conversion.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention.
In figure, 1. goal mouths, 2. falling sphere pipes, 3. saunter ball groove, 4. shock plates, 5. piezoelectric ceramic plates, 6. capacitors, 7. 2 poles
Pipe switch, 8. lasers.
Specific embodiment
According to the figure, it is equipped with goal mouth 1 on 2 top of falling sphere pipe of tubular, is connected in falling sphere pipe lower part by bending section
Ball groove of sauntering 3, ball groove of sauntering tail end are provided with shock plate 4, and piezoelectric ceramic plate 5 is fixed on the inside of shock plate, is led on piezoelectric ceramic plate
It crosses conducting wire and is connected with capacitor 6, be connected with diode switch 7 at capacitor discharge end, diode switch and 8 circuit of laser connect
It connects.
The falling sphere pipe is glass tube.
The ball groove of sauntering is open channel-shaped.
Working principle:
Demonstrating ball has quality relative to earth plane, when the demonstration ball with quality is fallen in a manner of freely falling body from goal mouth
When, gravitional force is generated, gravitional force is entered in ball groove of sauntering by bending section with the energy velocity of acceleration of gravity, to terminal
It rolls, kinetic energy is generated in rolling process and rushes at the piezoelectric ceramic plate fixed on shock plate, under the influence of the impact force, piezoelectricity pottery
Porcelain plate produces electricl energy, and electric energy is accessed laser by capacitor and diode switch by electric energy, generates luminous energy.
After the completion of a movement, gravitation ball is brought back to goal mouth and continues repetitive operation, to fully understand that energy is converted
Process.
From the point of view of demonstrating step, demonstration ball produces potential energy in relative altitude whereabouts, and demonstration ball rolls in ball groove of sauntering will
Potential energy is converted to kinetic energy, and kinetic energy impact piezoelectric ceramic plate makes the impact force of kinetic energy be converted to electric energy, and electric energy is input to capacitor collection
Poly- electric energy, electric energy generate luminous energy by diode switch and laser.
Pass through presentation process, it is to be understood that the conversion process of potential energy, kinetic energy, electric energy, luminous energy, thermal energy.
When laser is lighted, the laser beam of high-energy is generated, if laser beam acts on paper, can also generate thermal energy,
Paper is set to get hole.
By the practical operation of this conversion equipment, student can be made to understand the process and principle of energy conversion.
Feature:
For student, the demonstration of the present apparatus deep enough can understand the mechanism of energy conversion, for grasping conversion process of energy
It is highly beneficial, it is helpful that society is entered into student.
