Description

Technical Field

[0001] The utility model relates to the technical field of electric power simulation test, in particular to electric power simulation test equipment. Background Art

[0002] The power simulation test is used to simulate various power working scenarios. It is mostly used in teaching, demonstration or experimental processes. It can help people observe various power working scenarios more intuitively and clearly, and accelerate people's understanding of various power working principles.

[0003] In primary and secondary school teaching activities, students will learn that the conductivity of materials of different materials is different, and conductivity is a very abstract concept. In order to help students better understand the concept of conductivity, conductivity simulation test equipment will be used to intuitively demonstrate the differences in conductivity of different materials.

[0004] The Chinese utility model patent with patent application number CN201820220732.5 records an electric power simulation test equipment, which discharges the lightning rod through the set discharge needle, and the lightning rod is connected to a secondary light-emitting tube and a test board. Since different lightning rods are connected to test boards of different materials, when the staff turns on the corresponding discharge needle switch, the discharge needle will discharge the lightning rod, and then the current enters the test board of the corresponding material through the lightning rod and finally enters the light-emitting diode through the grounding wire. Since the conductivity of different test boards is different, the brightness of the light-emitting diode will also be different, so that the difference in the conductivity of test boards of different materials can be intuitively displayed. However, in the above setting, multiple lightning rods and test boards of different materials are arranged in sequence from front to back on a fixed platform. In this way, when demonstrating to students, students need to surround the fixed platform to fully and intuitively observe the brightness of each light-emitting diode, or the teacher needs to rotate the working platform to a vertical position to facilitate students to observe, which brings trouble to the teaching demonstration of the simulation experiment. Utility Model Content

The advantage of such an arrangement is that the teacher only needs to rotate the turntable to make the elastic conductive sheet contact and connect with different conductive blocks to perform power-on demonstration of different test circuits, which simplifies the demonstration operation and improves the practicability of the equipment.

[0009] Preferably, multiple pairs of mounting grooves are provided in annular shapes at equal angles on the outer circumferential surfaces of the two turntables, and magnetic blocks are fixedly connected to the bottom walls of the multiple pairs of mounting grooves. Two iron blocks are symmetrically and movably inserted in each pair of mounting grooves, and the two iron blocks are respectively adsorbed by the two magnetic blocks. The mounting plate is rotatably connected between the adjacent sides of the two iron blocks in each team through a damping shaft. The advantage of such a setting is that the installation work of the mounting plate can be simplified, and the angle of the mounting plate can be adjusted by rotating the mounting plate through the damping shaft, thereby facilitating students to see the test circuits on multiple mounting plates at the same time, thereby enhancing the effect of the test demonstration.

[0010] Preferably, it also includes a rotating member arranged between the side surfaces of two adjacent mounting plates, wherein the rotating member is two symmetrically distributed deformable metal rods, and the two ends of the deformable metal rods are respectively fixedly connected to the side surfaces of two adjacent mounting plates. The advantage of such an arrangement is that it allows the teacher to directly remove the mounting plate from the mounting groove, and then, under the support and variability of the deformable metal rods, can more flexibly adjust the position and angle of each mounting plate, thereby further improving the effect of the experimental demonstration and greatly improving the practicability of the equipment.
