Description
Technical field
The utility model relates to
OnePlant the seepage flow electricity draft experiment instrument of automatic reading, specifically relate to a kind of teaching test device that can read the gate dam base seepage flow under pressure hydroelectric analoguesi-mulation of equipotentiality point coordinate position automatically.
Background technology
Exist mathematical similarity between seepage flow and the current phenomena.Because these two kinds of flow fields all can be described with Laplace's equation, so can compare mutually between its corresponding physical quantity, and make under the similar situation of geometric configuration phase Sihe boundary condition at model, the method of available survey equipotential line is measured the equipotential line in the seepage field, again with utilizing the quadrature principle to draw streamline, obtain the seepage flow drift net, thereby try to achieve the hydraulic elements of arbitrfary point in the seepage field, as osmotic pressure, seepage velocity, hydraulic gradient, seepage flow and uplift pressure etc.
Yet, in the process of the hydroelectric analoguesi-mulation experiment of doing seepage flow under pressure, probe elicites the step that reads coordinate behind the isopotential point has too many difficulties to cope with the experimenter, naked eyes are difficult to accurate location, and reading makes eyes tire out for a long time, conduct electricity the water layer refractive effect of liquid, reading produces unavoidably than mistake, has influenced teaching efficiency in addition.
Summary of the invention
The purpose of this utility model is to have overcome deficiency of the prior art, and a kind of gate dam base seepage flow under pressure electricity plan teaching test device that can read the equipotentiality point coordinate automatically and show reading is provided.
In order to solve the problems of the technologies described above, the utility model is to be achieved through the following technical solutions:
OnePlant the seepage flow electricity draft experiment instrument of automatic reading, it is characterized in that: its structure comprises SX-1 type signal source, piezoelectricity coordinate display, electric plan dish, has set up piezoelectricity coordinate display module on the described SX-1 type signal source structure; Described electric plan dish inside has increased the single chip resistance pressure sensing layer.
Described single chip resistance pressure sensing layer is arranged on waterproof coordinate ply of paper bottom, and the pressing detection input is connected on the connector lug of piezoelectricity coordinate display by control circuit.
Compared with prior art, the beneficial effects of the utility model are:
In doing the hydroelectric analoguesi-mulation experimentation of seepage flow under pressure, probe elicites the coordinate figure that can show current spy contact behind the isopotential point automatically, make things convenient for read-record, the experimental error that can reduce the water layer refraction simultaneously again and bring with kopiopia is more accurate than naked eyes reading.
Description of drawings

Fig. 2 is electric plan dish partial view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
As shown in Figure 1, 2, the utility model is made up of SX-1 type signal source 1, piezoelectricity coordinate display 2, electric plan dish 3, wherein SX-1 type signal source dial plate mainly is made up of shift knob 4, digital indicator 6, frequency adjustment knob 7, output adjusting knob 8, range adjusting knob 9, three connector lugs are set in addition, color is followed successively by redly, red, black from left to right, connects upstream copper coin, probe 5, the downstream copper coin that confluxes that confluxes respectively; Piezoelectricity coordinate display 2 parts are made up of digital indicator 10 and connector lug, and this connector lug is connected to the single chip resistance pressure sensing layer 12 of electric plan dish 3; Electricity plan dish 3 mainly is made up of waterproof coordinate ply of paper 11, single chip resistance pressure sensing layer 12 and bearing 13.
After the electricity plan was coiled 3 adjusting levels, it was dark to inject the about 2cm of salt solution therein, behind connection and the inspection circuit, with SX-1 type signal source 1 and power connection, simultaneously range adjusting knob 9 was rotated to the position of 10V; The copper coin that confluxed in probe 5 and upstream again contacts, and rotation output adjusting knob 8 makes ammeter show 10V, and this moment, probe 5 confluxed copper coin when contacting with the upstream, and reading should show 0V; Measure each isopotential point respectively, and note the coordinate readings of corresponding measuring point digital indicator 10 in piezoelectricity coordinate display 2, each equipotential measuring point coordinate figure is painted on has retouched in advance on the square paper that electric plan coils 3 boundary profiles; At last describe streamline according to the characteristic of drift net.
Owing in electricity plan dish 3, embedded single chip resistance pressure sensing layer 12, and be connected to piezoelectricity coordinate display 2, show the measuring point coordinate automatically, significantly reduced the workload of experiment reading like this, also improved the accuracy of reading.
The undeclared part that relates in the utility model is same as the prior art or adopt prior art to be realized.
