Electrostatic power machine experimental instrument

Abstract

The invention discloses an electrostatic power machine experimental instrument and belongs to the field of physics teaching experiment instruments of universities and middle schools. The electrostatic power machine experimental instrument is mainly composed of an electrode plate, a swing plate, a high-voltage electrostatic power supply, a rotation wheel and a motion conversion rod. The electrostatic power machine experimental instrument is substantially different from prior arts and has the following advantages: when the distances between positive and negative electrode plates and voltages are fixed, the larger the swing plate is, the more the swing plate carries charges and the larger the applied electrostatic acting forces are, power is strong and is close to constant-force output in the swing process of the swing plate, since the swing plate is symmetrically distributed at the two sides of a plastic rotation disc rotation shaft, equidirectional driving moment can be generated, besides, the apparatus can also be enabled to placed at any inclination angles without affecting work, through the swing rod, the driving moment generated on the rotation wheel can be increased, and the rotation wheel is more easily driven to rotate when the motion conversion rod is used for outputting power. The power machine provided by the invention is low in manufacturing cost and low in operation cost, is free from pollution, is quite simple to manufacture and obvious in effect and increases education functions in classroom teaching, thereby being of great significance and having great development prospect.

Description

technical field [0001] The patent of the invention relates to an experimental instrument for demonstrating electrostatic drive, and belongs to the field of experimental instruments for physics teaching in universities and middle schools. Background technique [0002] In college physics courses, static electricity is an important content, and the application of electrostatic induction is the content that everyone pays attention to. Over the years, in order to help students correctly understand this concept and apply electrostatic induction, some demonstration experiments have been set up in conjunction with teaching, such as electrostatic jumping ball experiment, electrostatic pendulum ball experiment, electrostatic roller experiment, electrostatic blower, and the scale static electricity sensor designed by the inventor of this patent. Jumping ball tester, etc. Although the existing electrostatic demonstration devices have solved some needs to a certain extent, they lack furt...
