Abstract
The utility model relates to an imitative step-voltage teaching projection demonstrator, mainly composed of a panel, a water tank, and a human body slide. The inner walls of the water tank are provided with copper bands, the middle part of the water tank is provided with the positive electrode of an external power supply, a chute is arranged on the panel, and the inner part of the chute is provided with a manual slide block that is connected with the human body slide, and both legs of the human body slide are respectively provided with a current measuring rod that can detect the voltage between both legs thereof in the water tank. The utility model has the advantages of simple structure and convenient operation, and students can sharply observe step voltage experiments on screens in classrooms with projectors, which facilitates teaching and increases the quality thereof.
Description
The utility model is a kind of simulation step voltage teaching projection demonstrator that uses in teaching process.
People generally know, hi-line falls earthward, exist voltage on the ground with between the different each point of high-tension bus-bar broken end distance, when people come into the high-tension bus-bar broken end, bipod stands in from landing on the far and near different position of electric wire, electric current flows through human body and causes the electric shock that strides, just have voltage between the bipod, thereby form step voltage, striding, greatly then voltage is big, the little then voltage that strides is little, the closer to the high-tension bus-bar broken end, voltage is high more, and the teacher can only say something with figure when teaching, can't demonstrate intuitively to the student, teaching efficiency is not really desirable.
The purpose of this utility model is to provide a kind of simulation step voltage teaching projection demonstrator, demonstrates to the student during for teaching.
The utility model is achieved in that a kind of simulation step voltage teaching projection demonstrator, mainly by panel, tank, the human body slide plate constitutes, tank is arranged on the panel, the inwall of tank is equipped with the conducting metal circle, sink outer walls is extended with the negative terminal of external power supply, the tank middle part is provided with the positive electrode of external power supply, panel is provided with a chute, movable slider on the other hand is housed in the chute, described manual slide block is connected with a human body slide plate, the bipod of human body slide plate be equipped with respectively detectable in tank the survey torch of voltage between the human body bipod, described two survey the connector lug that torches are respectively equipped with the external voltage table.
Simulation step voltage teaching projection demonstrator structure of the present utility model is simple, easy to operate, utilizes projector, the student is sitting in just can clearly sees the step voltage experiment in the classroom on screen, has made things convenient for teaching, has improved quality of instruction.
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is the structural representation of facing of the present utility model;
Fig. 2 shows structural representation for of the present utility model cuing open.
With reference to figure 1, Fig. 2, simulation step voltage teaching projection demonstrator is mainly by panel 2, tank 4, human body slide plate 11 constitutes, tank 4 is arranged on the panel 2, water 3 is housed in the tank 4 during demonstration, the inwall of tank 4 is equipped with conduction copper band 12 or other metallic conductor, tank 4 outer walls are extended with the negative terminal 9 of external power supply, tank 4 middle parts are provided with the positive electrode 10 of external power supply, for the stereoprojection effect is arranged, tank 4 ovalizes, the lower-left end of panel 2 is provided with a chute 5, movable slider 8 on the other hand is housed in the chute 5, described manual slide block 8 is connected with a human body slide plate 11, for strengthening drop shadow effect's human body 13 and human body slide plate 11 usefulness pmma materials as one, panel 2 is made by pmma material too with tank 4, the bipod of human body 13 be equipped with respectively detectable in tank 4 the survey torch 6 of voltage between the human body bipod, described two survey the connector lug that torch 6 is respectively equipped with the sensitive voltage table 1 of external projection, in order to strengthen the demonstration effect, handled easily, the right crus of diaphragm of human body slide plate 11 is connected with people's leg control lever 7, according to the relative position relation of chute 5 with tank 4, human body control lever 7 also can be provided with the left foot with human body slide plate 11, for strengthening visual effect, strengthen student's memory, high pressure brandreth 14 also is decorated with in panel 2 upper right side, and convenient for projection, panel 2 is provided with the breach of placing projection voltage table 1.
During demonstration, prepare one of projector, one of screen, one of the sensitive voltage table of projection, one of 9 volts of power supply or dry cell, projector is set level, put steady, demonstrator of the present utility model is placed on the projector, put the projection voltage table in the upper left corner, survey torch connector lug on the human body left foot is connected on the voltage table negative pole end, the connector lug that right crus of diaphragm is surveyed torch is connected on the voltage table positive terminal, the positive electrode of sink center connects power positive end by line 15, it is extreme that the negative terminal of sink outer walls connects power-by line 16, open projector's switch, adjust picture position and focal length, make picture clear, human body slide plate and human body are shifted the left side onto, people's leg control lever is pulled the position of standing, in tank, pour 2/3rds water that impurity arranged into, open and simulate stride experimental power supply and projector power supply, people's leg control lever is pulled the position that strides, at this moment the voltage indication is just arranged on the voltage table, left hand is held panel, right-hand push is started movable slider human body and human body slide plate is slowly moved to the positive electrode of sink center, simultaneously, voltage raises gradually, and human body is the closer to " high pressure " (positive electrode of sink center) pick-up point, voltage is high more, pull people's leg control lever, it is big more to stride, and voltage is big more, it is more little to stride, and voltage is more little.
