Abstract

The utility model relates to a wind, rain, thunder, electricity comprehensive teaching experiment apparatus. A hollow pagoda-shaped casing is formed by stacking a base (1), an intake chamber (2), a boiler jacket (4), an auxiliary sleeve (7), an exhaust pipe (10), etc. An alcohol lamp (16), a small boiler (5) and a lightning generator are arranged in the casing, and a wind wheel (14), a fog rain cover (13) and feathers (12) are arranged outside the casing. The utility model can synthetically demonstrate nature phenomena, such as, wind, rain, cloud, boiling, steam work, light hot air, lightning, etc. The utility model can vividly and lucidly help primary and secondary school students recognize and comprehend the nature phenomena in an intuitional form.

Description

Wind, rain, thunder, electricity comprehensive teaching experiment apparatus

The utility model relates to the education experiment apparatus, particularly the experimental provision of middle and primary schools' meteorological knowledge teaching.

Spontaneous phenomenons such as wind, rain, mist, boiling, steam work done, hot-air are light, thunder and lightning are the rudimentary knowledge that must read in middle school physics and the primary school nature course, are still lacking a kind of vivid, clear and easy to understand comprehensive intuitively teaching aid of demonstrating above-mentioned various spontaneous phenomenon and explaining its principle in present middle and primary schools education experiment apparatus.

In order to inspire the understanding of students in middle and primary schools to above-mentioned more abstract, not familiar spontaneous phenomenon, and further it is deepened understanding and understanding, make meteorological knowledge teaching more vivid, clear and easy to understand, the purpose of this utility model provides a kind of comprehensive experimental device that can demonstrate spontaneous phenomenons such as wind, rain, cloud and mist, boiling, steam work done, hot-air are light, thunder and lightning simultaneously.

This experimental provision comprises one by base (1), air inlet seat (2), boiler jacket (4), auxiliary sleeve (7), gas outlet (10) etc. vertically is superimposed as the pagoda shape housing of hollow, in air inlet seat (2), place a spirit lamp (16), open an air intake opening and load onto draft tube (3) at the side of air inlet seat (2), a bite arcola (5) is installed on the suitable height of boiler jacket (4) middle distance spirit lamp, the steam jet (15) of a both ends open of side top welding of arcola, steam jet passes boiler jacket (4) and is upturned, the fog precipitation cover (13) that a likeness in form glass cylinder is arranged in steam jet (15) port top, the fog precipitation cover is fixed on the outside of auxiliary sleeve (7) with support (9), rim of a cup is aimed at steam jet port (15) down, the suitable distance of a bearing of trend little wind wheel of last installation (14) at steam jet (15), in auxiliary sleeve (7), install one by dry cell (21), electric capacity (22), solenoid (24), the thunder and lightning generator that transistor (23) is formed, behind the output lead of thunder and lightning generator (11) pushbutton switch of series connection (8), draw housing, erect in the top of gas outlet (10) regularly at a distance of certain distance at lead (11) two ends, hangs pugil feather (12) on the top of lead (11) again.

Concrete structure of the present utility model has following accompanying drawing to provide:

Fig. 1 is the front elevation of experimental provision provided by the utility model

Fig. 2 is the scheme of installation of thunder and lightning generator

Further describe embodiment below in conjunction with accompanying drawing, and describe its experimental demonstration step in detail.

Become pivot bush unit between base (1), air inlet seat (2), boiler jacket (4) and auxiliary sleeve (7) four joints, so that place or take out spirit lamp (16) and add water for arcola (5).Convenient in order to add water, open filler at the top of arcola (5), and load onto lid (6).Steam jet (15) is fixed with the employing welding that is connected between arcola (5) and the boiler jacket (4).The thunder and lightning generator of being made up of dry cell (21), electric capacity (22), coil (24), crystal trisome utmost point pipe (23) is installed in the auxiliary sleeve (7), and pushbutton switch (8) is installed on the outer wall of auxiliary sleeve (7).Another scheme of implementing, thunder and lightning generator and button (8) also can be installed in the base (1).

The experimental demonstration step of this experimental provision:

1. open arcola lid (6), add 1/2 clear water in the arcola (5), light spirit lamp (16), arcola (5) is heated, the water in boiler is boiled when sending " Da Da ... " sound, and this is referred to as " boiling ".

2. drawing a match, combustion head is placed air intake opening (3), pyrotechnics enters in the air inlet seat (2) slowly along air intake opening, illustrates that the higher cold air of atmospheric density flows to the lower hot-air district of atmospheric density, shows the origin cause of formation of " wind ".

3. the water when arcola (5) lining boils, and steam promotes wind wheel (14) and ceaselessly rotates from steam jet (15) ejection, and this is called " steam work done ".

4. steam constantly from steam jet (15) ejection, is covered by fog precipitation cover (13), occurs the vaporific steam of milky in cloche, and this is referred to as " cloud and mist ".

5. the interior steam of fog precipitation cover (13) increases gradually, and droplet constantly falls down water droplet from the cloche wall, and this just becomes " rain ".

6. cold air enters from draft tube (3), is discharged from the gas outlet (10) on top by the heating installation (heat transmission gas) of spirit lamp (6) heating, and the feather (12) that hangs over exhausr port (10) top is waved with gas, and Here it is " hot-air is light ".

7. press the button switch (8), at two leads adjacent to each other (11) the sound and electric spark that " whip ... " sent at the tip, this is called " thunder and lightning " phenomenon.

The utility model is simple in structure, easy to use, solved in the primary school nature section in air part and the middle school physics calorifics in " boiling ", " wind ", " rain ", " cloud and mist ", " steam work done ", " hot-air is light " and the electricity seven experiments such as " thunder and lightning " origin cause of formation basically.
