The utility model has the advantages of no leakage, high precision, low cost, good repeatability, and simple and time-saving operation in the process of experiments, and the utility model can be suitable for all universities and high schools to make the electric field mapping experiments.
Description
The utility model belongs to the experiment teaching instrument that is applied to the physics subject class, specifically is used for the experimental provision that simulate electric field distributes.
Existing electric field plotting board has adopted spark recording paper (conductive paper) to set up the water pond formula static field description device that electrostatic field (seeing " electric field drawing apparatus instructions " (Tsing-Hua University scene instrument plant) and " electrostatic field equipotential line drawing apparatus instructions " (Yunling, Shanghai instrument plant)) or the fifties generally use.When experiment the former owing to exist the graphite linings of conductive paper inhomogeneous, and make its resistivity inhomogeneous, loose contact between electrode and the conductive paper, so that experimental error is bigger; And latter's ubiquity drainage, described point is time-consuming and be prone to mistake, and shortcomings such as inconvenience are used in experiment.
The purpose of this utility model is, existing device is carried out structural improvement, and a kind of two-layer equation tank electric field plotting board is provided, no drainage, and experimental precision improves, and is easy to use, and experimental cost reduces.
The utility model adopts following scheme: the battery lead plate (8) that is placed in one with a tank (10) and an end replaces spark recording paper in the known same device and top electrode thereof.Its tank (10) is hot-forming.Battery lead plate (8) and lead press strip (13) and lead (12) are hot-forming together.Electrode (6), (7) and binding post (9) are housed on battery lead plate (8).
The utility model device is formed by combining by device mounting (11), recording paper sheet (14), mobile probe seat (1), tank (10) and battery lead plate (8).Wherein install mounting (11) and connect firmly with recording paper sheet (14) and become upper and lower two-layer together, be placed with tank (10) and mobile probe seat (1) on the device mounting (11); Record print needle (5) and probe (4) are fixed on the mobile probe seat (1); Tank (10) is under recording paper sheet (14); Accompany recording chart (3) on the recording paper sheet (14); The end that battery lead plate (8) is equipped with electrode (6), (7) immerses in the water in the tank (10), the end that binding post (9) is housed surfaces, probe (4) places tank (10), and the lead (12) between electrode (6), (7) and the binding post (9) is sealed by lead press strip (13).
Referring now to accompanying drawing the utility model principle of work is sketched: be filled with water at the tank of putting into battery lead plate (8) (10) during experiment, after the energising, then in tank (10), produce current field, seek the equipotentiality point by probe (4), measure its equipotentiality point with voltage table or sensitive galvanometer, and the position of equipotentiality point by printing on the recording chart (3) with the record print needle (5) of probe (4) with coordinate position.To difform electroplax (6), (7), then on recording chart (3), survey and draw out different distribution map of the electric field.
The utility model adopts the two-layer equation sink structure, and tank (10) is hot-forming, so there is not drainage; And with tank (10) and battery lead plate (8) replaced spark recording paper and on electrode.Experimental precision improves, and experiment material is taken reduction, good economy performance, and easy to use saving time is convenient to maintenance and management.
Fig. 1 is an overall front view of the present utility model.Wherein 1 is the mobile probe seat, and 2 is little binding post, and 3 is recording chart, and 4 is probe, and 5 are the record print needle, and 6,7 is electrode, and 8 is battery lead plate, and 9 is binding post, and 10 is tank, and 11 is the device mounting, and 14 is recording paper sheet.
Fig. 2 be among Fig. 1 A-A to cut-open view.Wherein 1 is the mobile probe seat, and 4 is probe, and 6,7 is electrode, and 8 is battery lead plate, and 9 is binding post, and 10 is tank, and 11 is the device mounting, and 12 is lead.
Fig. 3 is the vertical view of the battery lead plate 8 that adopts of the utility model.Wherein 6,7 is electrode, and 8 is battery lead plate, and 9 is binding post, and 12 is lead, and 13 is the lead press strip.
Fig. 4 be among Fig. 3 B-B to cut-open view.Wherein 6,7 is electrode, and 8 is battery lead plate, and 9 is binding post, and 12 is lead, and 13 is the lead press strip.
Accompanying drawing is described to be the embodiment that the utility model is used for the coaxial cylindrical surface electrode.With reference to accompanying drawing as can be seen, this embodiment is by device mounting (11), recording paper sheet (14), mobile probe seat (1), tank (10) and battery lead plate compositions such as (8).Wherein install mounting (11) and connect firmly with recording paper sheet (14) and become upper and lower two-layer together, be placed with tank (10) and mobile probe seat (1) on the device mounting (11); Record print needle (5) and probe (4) are fixed on the mobile probe seat (1); Tank (10) is under recording paper sheet (14); Accompany recording chart (3) on the recording paper sheet (14); In the water in the end immersion tank (10) that electrode (6), (7) are housed of battery lead plate (8), the end that binding post (9) is housed surfaces, top, edge at tank (10), probe (4) places tank (10), and the lead (12) between electrode (6), (7) and the binding post (9) is sealed by lead press strip (13).
Be filled with water at the tank of putting into battery lead plate (8) (10) during experiment, then in tank (10), produce current field after the energising, electricity consumption flow field simulation electrostatic field, seek the equipotentiality point by the probe (4) that is fixed on the mobile probe seat (1), the voltage table or the sensitive galvanometer that link to each other with little binding post (2) are measured the equipotentiality point, and with the position of equipotentiality point by being printed on the recording chart (3) with the record print needle (5) of probe (4) with coordinate position; Measure different equipotentiality points, each equipotentiality point of different electromotive forces is linked to be smooth curve, then become equipotential line.According to the equipotential line relation vertical with line of electric force, the line of electric force that draws, thus survey and draw out the distribution map of the electric field of coaxial cylindrical surface (cable) with the method for simulation.Use difform electrode (6), (7), then on recording chart (3), survey and draw out the distribution map of the electric field of different electrodes.
