Abstract

The invention relates to the technical field of science popularization education, and in particular relates to an inertia centrifugal phenomenon presentation device suitable for a science popularization venue. The device comprises a control cabinet and a rope throwing mechanism arranged above the control cabinet, wherein the rope throwing mechanism comprises a motor, a rope, a rope outlet, a rope pressing module and a handle; and the control cabinet comprises a single chip and a frequency converter, the single chip is used for setting parameters, and the frequency converter is used for controlling the rotating speed of the motor. The device disclosed by the invention is simple in operation and easy to maintain, the audience can visually observe the inertia and centrifugal force of the rope in the movement process through different rope throwing modes of the rope throwing mechanism, and thus the device is suitable for conveniently popularizing the inertia knowledge for the audience in the science popularization venue.

Description

technical field [0001] The invention relates to the technical field of popular science education, in particular to an inertial centrifugal phenomenon demonstration device suitable for popular science venues. Background technique [0002] Inertia and centrifugal phenomena are the key points and difficulties in middle school physics. To understand inertia, only by observing the phenomena can we draw intuitive conclusions, so that students can learn in fun and deepen their understanding of knowledge. In order to help teachers effectively teach, a series of demonstration devices have appeared. The existing technical centers such as patent publication numbers CN106023733A, CN202058349U, CN204884352U, CN204680270U, ​​etc. have all done research on inertial phenomena, but their commonality is that they are all It is suitable for the educational category of school teaching; combined with the current situation of domestic science and technology venues, due to its unstable structure a...
