Abstract
The utility model provides a portable multifunctional electrostatic-field demonstrator for the technical field of experiment demonstrators in teaching, characterized essentially in that the demonstrator comprises a rectangular base plate which has a power supply and a DC step-up transformer under it, a functional switch and an inching button switch on one side and a rectangular plastic base tray; the plastic base tray contains a square container which has bails on the side, metal balls or metal electrode plate inside, and light bulb(s) under; on the right top of the base plate is a switch for the light bulb, two screws to fix wax paper strips, a T-shape screw support and an electroscope. Because of the above technical plan, compared with the other electrostatic field demonstrators existing in the market, the utility model has a more integrated structure, more inclusive functions and easier operation, so that students can observe clearly in different ways.
Description
Technical field
The utility model belongs to teaching and experimental demonstration instrument technical field, is specifically related to a kind of portable multi-function electrostatic field magnetic field demonstrator.
Background technology
At present, the student is when study electrostatic field course, and some principle is by teacher's operation experiments, the student is come into plain view, be convenient to learn understanding and grasp like this, but teacher is when doing the static lecture experiment to these principles, obvious in order to make experiment effect, must use higher electrostatic potential, teacher does experiment like this, operational hazards, and student viewing is unclear, effect is not directly perceived, and the demonstration project is few.
Summary of the invention
The purpose of this utility model designs that a kind of demonstration project is many, and effect is directly perceived, and is easy to use, safety, portable multi-function electrostatic field magnetic field demonstrator simple to operate.
The technical scheme that the utility model is taked is to have base plate, base plate is rectangle, four jiaos in rectangle base plate bottom are provided with supporting leg, below described base plate, be provided with power supply and DC booster converter, be provided with functional switch and inching button switch on one side of base plate, another side at base plate is provided with rectangle plastics chassis, in described chassis, be placed with square container, be provided with in the positive side of described container carry anti-, in described container, be provided with Metal Ball or metal electrode board, bottom at described container is provided with bulb, the right on base plate, corresponding container is provided with bulb switch, on base plate by contain the container plastic dish outer in the middle part of, output links to each other with high-voltage electrostatic power to be provided with two high-pressure electrostatic wiring nut, can adorn by screw, be fixed with two screws and a T-shape screw frame of paraffin paper bar in addition, electroscope, and the mixed castor oil fluid bottle that the hair bits are arranged, also have the shielded metal cylinder mould, the screw on the be installed in high-pressure electrostatic nut of the reflective meaning of Band clamp and two band springs is in the base plate two sides, be separately installed with carrying handle, demonstration finishes and can hold.
Functional switch and inching button switch all produce by control battery low-voltage direct electric control high-pressure electrostatic, high-pressure electrostatic is connected on the two tool hold-doun nuts, difference according to doing demonstration, can load onto different web members on the nut, pass through web member, high-pressure electrostatic is connected on the screw that is fixed with the wax bar, links and pour in the transparent vessel on the metal or metal electrode board that mixes the castor oil container that the hair bits are arranged, just demonstrate different test acting forces, electric force lines distribution situation or other effect.
Utilize this instrument can do following demonstration:
1, electric charge interphase interaction power; 2, the shape of the formed line of electric force of equivalent xenogenesis electric charge; 3, the shape of the formed line of electric force of equivalent like charges; 4, the line of electric force shape of difference electric charge; 5, the line of electric force shape of uniform electric field; 6, be in the strong situation of internal ground conductor in the uniform electric field during electrostatic equilibrium; 7, electric field is the particular matter that energy is arranged, and it can make electroprobe shinny, on the equipotential surface electroprobe brightness everywhere the same, the formed electric field of point charge, electromotive force reduces gradually along line of electric force, the electroprobe display brightness by bright to dark, to fading away.Student viewing can be borrowed bulb and reflective mirror direct viewing, also can amplify by the slide projector projection and watch, and this instrument is not subjected to humid environment degree and Temperature Influence, and teacher does not directly contact high-tension electricity, handling safety.
Because the utility model taked above technical scheme, it is compared with electrostatic field demonstrator in the market, have structure-integrated, perfect in shape and function, easy-to-operate, the student can watch advantages such as clear by different approaches.
Accompanying drawing further specifies architectural feature of the present utility model below in conjunction with accompanying drawing and example.
Fig. 1 is the utility model general structure synoptic diagram.
Embodiment
As shown in the figure, the utility model has base plate 1, on base plate, be provided with vinyl disc 2 by operator's opposite side, in vinyl disc, be placed with several transparent plastic containers, battery and DC booster converter are installed under base plate, on base plate, depend on the operator on one side, be provided with third gear functional switch and point driving switch, at the nut that high-pressure electrostatic is set by middle part, vinyl disc outside, below corresponding each container center, a miniature bulb is installed respectively, on bank light bubble the right, be provided with the control bulb switch, bulb is received on the power supply by switch.On base plate, fund-raising is placed with T-shape attaching screw frame, and the attaching screws of two band springs are fixed with the screw of paraffin paper bar above two, the shielding cylinder mould, and electroscope is contained the fluid bottle that castor oil mixes the hair bits, the reflective mirror of Band clamp, opening Wiring nose.
