A hydropower analog experiment device with two-dimensional motion platform measurement

Abstract

The invention discloses a hydroelectric analogue simulation experimental device with a two-dimensional motion platform measurement function. The hydroelectric analogue simulation experimental device comprises a model basin, a probe and a hydroelectric analogue simulation experimental instrument connected with the probe. An electricity-conducting two-dimensional motion platform is arranged on the model basin. An X-axis ruler and a Y-axis ruler are marked on the two-dimensional motion platform. The probe is mounted on the two-dimensional motion platform and is electrically connected with the two-dimensional motion platform. The hydroelectric analogue simulation experimental device has the advantages that the electricity-conducting two-dimensional motion platform is applied to the hydroelectric analogue simulation experimental device innovatively, a dragging guide line conventionally applied to the probe is omitted, and a drag-free guide line is used, so that the problem that a flow field is affected by the fact that the dragging guide line is prone to soaking is solved; the X-axis ruler and the Y-axis ruler are marked on the two-dimensional motion platform, so that the problem of measurement errors caused by the fact that the probe is out of plumb easily as being held by hands is solved; a full-scale amplification and regulation circuit is applied innovatively, equipotential line values, in percentage, of measuring points can be displayed directly by the experimental instrument, and manual conversion is not needed.

Description

technical field [0001] The invention relates to the field of teaching experiment instruments, in particular to a hydropower analog experiment device with a two-dimensional motion platform for measurement without drag wires. Background technique [0002] Hydropower comparative experiment is one of the traditional classical experimental contents. This experiment is a hydropower analogy experiment using the current flow field to simulate the seepage flow field or the laminar flow field. The experimental principle is that the two physical fields of the electric field and the seepage (laminar flow) field can be described by the same mathematical equation. That is to say, they are all the same Laplace equation, the main variable flow field of the equation is the water head H, and the electric field is the voltage V. The experimental principle is mature in theory, and the experimental method is classic and credible. The purpose of the experiment is to measure and draw 9 equipotent...
