According to the electrostatic demonstrating instrument, high charge accumulating speed can be obtained, and influences caused by charge loss are lowered simultaneously; and the electrostatic demonstrating instrument is suitable for experimenting in various environments, can be used for obtaining static electricity in a short period of time even in a damp environment, and can be used for generating a higher static voltage and obtaining an ideal experiment effect.
Description
Technical field
The utility model relates to a kind of Physical Experiment apparatus for demonstrating, particularly a kind of Physical Experiment static demonstrator that electrifies that drips.
Background technology
Dripping electrifies is to shift and stored charge by the charged water droplet of being responded to; The Physical Experiment static demonstrator that electrifies of dripping of the prior art comprises dripping device, water container and induction coil; Dripping device forms single water droplet stream, and induction coil is processed column by metal material, and water container integral body is processed by alumina based material; When external environment condition becomes humidity; The a large amount of negative ions that carry in the air will cause the quick loss of induced charge, at this moment traditional electrizer that drips DeGrain that electrifies, even can not electrify.Therefore, the static lecture experiment generally requires under air dried environment, could produce comparatively significantly electrostatic phenomenon.
Summary of the invention
The utility model technical matters to be solved is the deficiency to prior art, provide a kind of reasonable in design, static demonstrator fast, that can prevent charge loss electrifies.
The utility model technical matters to be solved is to realize through following technical scheme.The utility model is a kind of static demonstrator; Comprise from top to bottom rack-mount successively dripping device, 2 induction coils, 2 water containers and 1 electrometer; Said dripping device comprises aqua storage tank; The aqua storage tank lower end is connected with two water droppers through outlet pipeline, induction coil and water container be positioned at successively water dropper under, be characterized in: described water dropper is respectively equipped with 4 weep pipes; Described induction coil is the circular coil that is formed by the insulated conductor coiling; Described water container is the insulation water container, and the bottom in the water container is respectively equipped with aluminium flake; The end of each induction coil lead is connected on the aluminium flake with its water container that intersects, and one of them aluminium flake is connected with electrometer through lead.
Compared with prior art; The utility model can obtain electric charge accumulating rate faster, reduces the influence that charge loss brings simultaneously, is applicable under various environment to experimentize; Even at comparatively moist environment; Also can obtain static at short notice, and can produce higher electrostatic potential, obtain desirable experiment effect.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
Following with reference to accompanying drawing, further describe the concrete technical scheme of the utility model, so that those skilled in the art understands the present invention further, and do not constitute restriction to its right.
Embodiment 1, with reference to Fig. 1, and a kind of static demonstrator that electrifies that drips; Comprise from top to bottom rack-mount successively dripping device, 3,2 water containers 4 of 2 induction coils and 1 electrometer; Said dripping device comprises aqua storage tank 1, and aqua storage tank 1 lower end is connected with two water droppers 2 through outlet pipeline, and outlet pipeline is provided with water flow control valve; Induction coil 3 and water container 4 be positioned at successively water dropper 2 under, described water dropper 2 is respectively equipped with 4 weep pipes; Described induction coil 3 is the circular coils that formed by the insulated conductor coiling; Described water container 4 is insulation water container 4, and the bottom in the water container 4 is respectively equipped with aluminium flake 5; The end of each induction coil 3 lead is connected on the aluminium flake 5 with its water container that intersects 4, and one of them aluminium flake 5 is connected with electrometer through lead.
During experiment; Be connected with two water droppers 2 on the aqua storage tank 1 of dripping device; Open the water flow control valve between aqua storage tank 1 and the water dropper 2, make water dropper 2 form discontinuous water droplet stream, water down drips from the weep pipe tip; Water droplet falls into water container 4 after passing induction coil 3 respectively; Wherein the wire termination of induction coil 3 all is connected on the aluminium flake 5 with its water container that intersects 4 bottoms, and water droplet can bring water container 4 electric charge of denier by accident, causes certain water container 4 to have the electric charge of trace.Suppose that one of them water container 4 has obtained a little positive charge, then coupled induction coil 3 also can have certain positive charge.Because the electrostatic induction effect, the positive charge on the induction coil 3 can attract negative charge in the water droplet of the water dropper corresponding with it 2.The water droplet of water dropper 2 will carry negative charge and splash in the water container 4, and 4 electronegative accumulation of water container are increased, and can make another induction coil 3 with last certain negative charge so again, thereby attract positive charge in the water droplet of the water dropper corresponding with it 2.The water droplet of water dropper 2 falls in the water container 4, and 4 positively charged accumulation of water container are increased.This process makes each induction coil 3 and water container 4 obtain more electric charge; Form stronger electrostatic induction, therefore two water containers 4 with electric charge be on the increase, be exponential increase in time; The static voltage that is produced also constantly increases, even can reach volts up to ten thousand.
