Abstract

The invention discloses a simulated seismoscope experimental facility, which comprises a small ball, a thick column, a lever, a lever trestle table, a frog mouth, a thick column platform and a bottom plate, wherein the thick column platform and the frog mouth are adhered to the bottom plate by glue; the lever trestle table is adhered to the edge of the thick column platform by the glue; the lever is arranged on a lever support; and the thick column is uprightly arranged in the center of the thick column platform. When seismic waves are generated in a certain direction, the thick column is tilted towards the direction, presses down the lever, and makes the small ball on the tip of the lever drop into the frog mouth below the small ball, so that the direction of earthquake can be judged according to the azimuth of the frog mouth. The simulated seismoscope experimental facility has the advantages of low cost and simple structure, and is suitable for teachers to demonstrate experiments.

Description

Technical field: [0001] The invention relates to a teaching demonstration device, in particular to a simulated seismograph experiment device in high school physics teaching. Background technique: [0002] Infiltrating patriotism education in today's teaching is a requirement of the teaching syllabus, so that students can understand the great invention of ancient Chinese scientists - Zhang Heng's seismograph is an important content in the teaching of the balance of force on objects. But at present, the education equipment department does not equip the school with this device, and no manufacturer has developed the required equipment suitable for middle school physics teaching. Invention content: [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to develop a simulated seismograph experiment device suitable for middle school physics teaching, so as to meet the needs of high school physics teaching. [0004] Goal of the invention of ...
