Abstract

Disclosed is an imitation experiment device for thunder and light, belonging to an educational apparatus. The utility model provides an experiment device for imitating thunder and light in rain, and visually shows the principle of the lightning rod. The utility model comprises a box body. An iron plate and a lightning rod are arranged on the surface of the box body; a wire loop is arranged on the pillar of the box body; a man mode in which a glow starter is provided is arranged on the iron plate; a static the high voltage generator circuit respectively connected with the iron plate and the wire loop by conductors is arranged in the box body.

Description

Atmospheric electrical phenomena simulated experiment device

Technical field:

The utility model is to belong to instruments used for education.

Background technology:

Proved that now the electricity that produces in thunder and lightning in the rain and the laboratory has identical character, promptly thunder and lightning is exactly a kind of electric discharge phenomena." kite " but of Franklin experiment danger close, the teacher must not advocate the student and repeat this dangerous experiment, this just caused the student can not firsthand experience to the essence of thunder and lightning, spontaneous phenomenon lacked intuitively is familiar with.

The utility model content:

The utility model is exactly at the problems referred to above, and a kind of analog demenstration atmospheric electrical phenomena in the rain is provided, and discloses the tester of lightning rod principle intuitively.

The utility model adopts following technical scheme: the utility model comprises casing, its structural feature is on the surface of casing iron plate, lightning rod to be set, the column of casing is provided with quoit, the human model that starter is arranged in being provided with on the iron plate is provided with the electrostatic high-pressure generator circuit that links to each other by the same respectively iron plate of lead, quoit in the casing.

The beneficial effects of the utility model:

1, analog demenstration atmospheric electrical phenomena in the rain, disclose the principle of lightning rod intuitively:

Owing on the surface of the utility model casing iron plate, lightning rod are set, the column of casing is provided with quoit, the human model that starter is arranged in being provided with on the iron plate is provided with the electrostatic high-pressure generator circuit that links to each other by the same respectively iron plate of lead, quoit in the casing; Just can on quoit, be equipped with alcohol cotton mass simulation thundercloud, flashing discharge between iron plate (representative ground) and alcohol cotton mass, the burning of alcohol cotton mass; Hold up lightning rod, will between alcohol cotton mass and lightning rod, discharge, with the principle of work that discloses lightning rod directly perceived;

2, simple in structure:

The utility model member is few, and body is simple, is easy to make, and is easy to popularize.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is annexation figure between the circuit of Fig. 1;

Fig. 3 is circuit theory diagrams of the present utility model.

Embodiment:

The utility model comprises casing 1, iron plate 2, lightning rod 7 are set on the surface of casing 1, the column 6 of casing 1 is provided with quoit 5, the human model 4 that starter 3 is arranged in being provided with on the iron plate 2 is provided with the electrostatic high-pressure generator circuit 8 that links to each other with iron plate 2, quoit 5 respectively by lead in the casing 1.

Electrostatic high-pressure generator circuit 8 is three parallel circuits of K switch series connection: electrostatic high-pressure source M, capacitor C, starter 3 and region of discharge D1.Electrostatic high-pressure source M is made up of field coil L1, the induction high-tension coil L2 of siliconized plate T and both sides.

Embodiment 1:

At first, human model 4 is placed on the iron plate 2, the alcohol cotton mass places on the quoit 5; The K that closes a switch, entire circuit is connected, and the heavy current that electrostatic high-pressure source M produces makes starter 3 glittering by heavy current between alcohol cotton mass, the human model 4; When holding up lightning rod 7, produce spark, discharge between alcohol cotton mass and the lightning rod 7, then human model 4 is with regard to safe impunity;

Embodiment 2:

At first, the alcohol cotton mass is placed on the quoit 5, the K that closes a switch, entire circuit is connected, and the heavy current that electrostatic high-pressure source M produces produces electric spark by the alcohol cotton mass, burns; If lightning rod 7 is holded up, between alcohol cotton mass and the lightning rod 7 point discharge takes place, but the alcohol cotton mass can not burn.

Claims

1, atmospheric electrical phenomena simulated experiment device, comprise casing (1), it is characterized in that on the surface of casing (1) iron plate (2), lightning rod (7) being set, the column (6) of casing (1) is provided with quoit (5), the human model (4) that starter (3) are arranged in being provided with on the iron plate (2) is provided with the electrostatic high-pressure generator circuit (8) that links to each other by the same respectively iron plate of lead (2), quoit (5) in the casing (1).
