Description
Technical field
The utility model relates to teaching and experiment equipment field, is specifically related to the hydroelectric analoguesi-mulation experimental provision that a kind of nothing drags the band two-dimension moving platform taking wire to measure.
Background technology
Hydroelectric analoguesi-mulation experiment is one of experiment content of traditional allusion.This experiment is a kind of hydroelectric analoguesi-mulation experiment of simulating seepage flow flow field or Laminar Flow with electric current flow field, its experimental principle is that electric field and these two kinds of physical fields of seepage flow (laminar flow) field can describe with the mathematical equation of same form, namely be all same granny rag Lars equation, the master variable flow field of equation is head H, and electric field is voltage V.This experimental principle is theoretical ripe, and experimental technique allusion is credible, experiment purpose be measure and draw out the voltage V of simulated flow pattern 10%, 20% ... 90% totally 9 equipotential lines.
Traditional hydroelectric analoguesi-mulation experimental provision drags chaining pin, the grid millimeter coordinate paper of pond basin dianegative lower liner, ac voltage signal generator and the general-purpose voltage table etc. taking electric wire to form by model basin basin, band.In model basin basin, can place the flow field model that different experiments requires, model boundary material impervious to water is gone along with sb. to guard him and is formed, according to boundary condition, border is respectively arranged with height, zero equipotential cylinder manifold, and other borders are the non-conductive border that insulating material makes.Insulating material commonly uses glass plate, organic glass, asphalt mixture, plasticine and insullac etc. traditionally.The conduction liquid of 1-2 centimetre is had, as tap water or light salt brine in the model boundary of model basin basin.Experimental work voltage is connected respectively at the high low side of current potential cylinder manifold, polarize to prevent cylinder manifold, the high-frequency ac voltage of usual employing 1000-2000HZ, the no-voltage of low termination ground connection, high-end conventional 10V voltage traditionally, and the flow field voltage equipotential line in border is divided into 1V 9 equipotential lines of the 1-9V being interval, with 10% of simulated flow pattern, 20% ... the equipotential line of 90%.If operating voltage is not 10V, 9 equipotential lines, magnitude of voltage possibility non integer value, makes troubles in experiment measuring.When measuring these equipotential lines in flow field, as measured with multimeter, then the negative terminal of multimeter is connected on the cylinder manifold of zero potential, and vertically insert in conduction liquid with the high-end chaining pin of multimeter, mobile chaining pin searches out required voltage point, writes down the coordinate on the pond basin dianegative lower liner grid millimeter coordinate paper of chaining pin indication.Each equipotential line needs to measure nearly 10 measuring points by such as the method.Be decorated with the grid graph paper of model boundary figure again with one by a certain percentage, according to each measuring point coordinate, in proportion measuring point be labeled on the figure being decorated with model grid graph paper.By waiting measuring point of voltage to be linked to be a curve, draw the equipotential line in flow field.
Traditional experiment devices and methods therefor has the following disadvantages and defect:
1, measurement instrument needs loose mail to configure, and the 10V audio signal generator lacked needed for experiment, the in recent years same quasi-instrument of what is called energy output audio 10V voltage purchased of market, reality can export ceiling voltage and be only below 9V, a lot of multimeter frequency does not respond, and causes inconvenience to user.Develop a hydroelectric analoguesi-mulation electric pilot electronic product, the blank filling up this field is necessary.
2, traditional experiment device, its chaining pin all takes formula conductor wire with dragging, and has dragged a long-tail bar, when measuring in pond, drag on the other hand and take wire, arrest chaining pin on the other hand, moving when measuring in model basin basin seeks a little, both inconvenient, again because wire immersion or chaining pin out of plumb cause measuring error.The hope that this " drags the tail taken " and be experimenter is cut off with innovation.
3, in traditional experiment device, with the grid millimeter coordinate paper of pond basin dianegative lower liner as survey coordinate reading, in experiment, coordinate student is easy to misread in length and breadth.Especially as a kind of experiment device for teaching, this grid graph paper as coordinate paper, tangible technology grade not.Do not welcome by student very much, often suffer that teachers and students blame for.If develop a kind of simple and easy and measurement of coordinates system of practicality, meeting experimental teaching requirement, is highly significant.
4, full scale verification will repeatedly be carried out in experimentation, and the verification of conventional apparatus full scale is inconvenient with adjustment, if can increase full scale verification regulatory function, can be experiment and brings convenience.
