Abstract
The utility model relates to a simulating electrostatic field plotter, which plots distribution of an electrostatic field by a simulating method and consists of a large-scale water tank, various electrodes, a cross rod and a tank bottom coordinate board, presses the electrodes by the cross rod, are electrically connected with the electrodes, can greatly improve surveying and mapping precision, can conveniently change the electrodes and increase the experience content and can basically avoid water leakage of the water tank.
Description
Affiliated field the utility model relates to a kind of physics experiment teaching instrument of describing distribution of electrostatic with simulation.
Background technology
The most analog electrostatic field drawing apparatus that use at present are sink structure, are medium with the tap water of weakly conducting rate, with the distribution of the current field distribution simulation electrostatic field in the water.Its structure generally is to be not more than in small-sized side's tank of 10cm a length of side, according to requirement of experiment electrode is set, in the bottom land perforate, and the fixed electorde position, and be connected with the groove external circuit.In case because the electrode stationkeeping just can not change, so each experiment content need be joined the tank and the electrode of a special use.The position of test point is determined and record adopts double-deck probe.
The main weak point of existing instrument: 1, precision is too poor.Because each experiment content will join a special-purpose tank and an electrode, and use factor such as double-deck probe location, cause sink size to be difficult for increasing, cause mapping precision very poor, in some experiments even can not verify the physical content of required confirmation fully.2, the position of electrode is completely fixed, and can't do change flexibly according to the experiment needs.Although 3 have adopted leak-proof measure, after instrument used a period of time, drainage still often took place in perforation place of tank.
Summary of the invention
At the above-mentioned weak point of existing instrument, the utility model is provided with the bottom land coordinate by strengthening sink size, adopt cross bar press down the mode fixed electorde and with methods such as electrode is electrically connected, increased substantially experimental precision and increased experiment content.
The basic structure of the analog electrostatic field drawing apparatus that the utility model provides as shown in Figure 1.It among the figure simulation mapping of distribution of electrostatic in the concentric cable.
This instrument has a square tank of large scale (1), and bottom land is covered with on the water-fast material thin slice prints the template (2) that rectangular coordinate and polar coordinates are made.Electrode is positioned over desired location on the template, and it highly is higher than tank, is pushed down by the cross bar (8) that crosses in the middle of the tank.Cross bar (8) is made up of two not isometric thin bonding jumpers, by insulating material web joint (9) combination.The cross bar two ends are placed on the interior (see figure 2) of vertical slot (10) of the outer metal crossbar mount (6) of tank, are pushed down by cross bar gib screw (7).Two crossbar mount are electrically connected with a utmost point of power supply and a bonding jumper of cross bar respectively.Cross bar has two big functions, and the one, push down electrode, it is fixed on the experiment desired location.The 2nd, be electrically connected with its electrode of pushing down.The cross bar lower edge of a long bonding jumper has a recess, its position in the mapping concentric cable during distribution of electrostatic used ring electrode above so that the two ends of cross bar can not touched with ring electrode simultaneously mutually.Back out the cross bar gib screw.Loosening cross bar just can freely change electrode, changes experiment content.The voltage test points position is determined according to template in the tank.
The major advantage of this instrument: 1, owing to can adopt yardstick to increase the tank of several times, factor such as the template positioning error is little, mapping precision significantly improves.2, can change electrode easily, increase experiment content.3, can avoid tank to leak substantially.

Embodiment
Among Fig. 1, the square tank of large scale of a band adjustable support leg, bottom land has the rectangular coordinate of printing and polar template.Place electrode by requirement of experiment on the template, electrode height is higher than tank, and the outer middle body of tank has two metal crossbar mount, and screw is arranged at seat top, and vertical slit is arranged in the middle of the screw, and groove depth surpasses the screw degree of depth.A cross bar that is combined by two sections not isometric thin bonding jumpers is by the web joint combination of insulation material.Two bonding jumper of cross bar is pushed down an electrode respectively.Its two ends place the slit of crossbar mount, are compressed by the cross bar gib screw.The two poles of the earth of AC power connect two crossbar mount respectively, and are electrically connected by cross bar and electrode.During energising, the tap water with faint conduction between the electrode in the tank is a medium, forms steady alternating current flow field, with the electrostatic field between the simulation identical electrodes.Distribute by the alternating voltage in the testing flume, depict the distribution of corresponding electrostatic field.The position coordinates of test point is determined according to template.Unclamp cross bar, can change electrode easily, change experiment content
Claims (2)
1. analog electrostatic field drawing apparatus, electrode places tank, it is characterized in that having a cross bar to push down electrode and be electrically connected with it.
2. analog electrostatic field drawing apparatus according to claim 1 is characterized in that cross bar is made up of two sections not isometric thin bonding jumpers, with the web joint combination of insulation.
