Portable electromagnetic gun demonstration experiment instrument for teaching experiment and using method thereof

Abstract

The invention discloses a portable electromagnetic gun demonstration experiment instrument for a teaching experiment. The portable electromagnetic gun demonstration experiment instrument includes a supporting base structure, a start and control structure, a trajectory external structure and a projectile acceleration structure, wherein the supporting base structure includes a gun body base (1) anda supporting bearing (2), and the supporting bearing (2) is arranged in the gun body base (1); the trajectory external structure includes a supporting part, a driving mechanism and a trajectory part,the driving mechanism includes a steering engine (4), and the trajectory part includes a trajectory (11) and a trajectory outer cover (10) arranged on the outer circumference of the trajectory (11); and the projectile acceleration structure includes a first-order acceleration coil (14) and a first-order acceleration photoelectric gate (15), and the start and control structure includes a steering engine control and Bluetooth receiving module (17), an energy storage device and a transmitting switch (19). The invention further discloses a using method of the portable electromagnetic gun experiment instrument. Electromagnetic gun demonstration experiment teaching can be realized, and the experimental sense and teaching effect are improved.

Description

technical field [0001] The invention belongs to the field of teaching experiment equipment, and more specifically relates to a portable electromagnetic gun demonstration experiment instrument used for teaching experiments. Background technique [0002] At present, most of the electromagnetic gun demonstration experiment instruments used in teaching in colleges and universities are bulky, simple in structure, non-adjustable in direction and invariable in angle, and the function of the instrument is relatively single, inconvenient to operate, and the effect is not satisfactory. It can only be arranged for students to organize visits and study in the demonstration laboratory in the school, which is far from meeting the needs of colleges and universities for classroom demonstration experiments of electromagnetism. Recognize the knowledge of electromagnetism. [0003] The Chinese invention patent with the patent number CN 103267447 A discloses a direct-current automatic launch o...

Problems solved by technology

[0002] At present, most of the electromagnetic gun demonstration experiment instruments used in teaching in colleges and universities are bulky, simple in structure, non-adjustable in direction and invariable in angle, and the function of the instrument is relatively single, inconvenient to operate, and the effect is not satisfactory

It can only be arranged for students to organize visits and study in the demonstration laboratory in the school, which is far from meeting the needs of colleges and universities for classroom demonstration experiments of electromagnetism. Recognize the knowledge of electromagnetism

[0003] The Chinese invention patent with the patent number CN 103267447 A discloses a direct-current automatic launch of double-acceleration electromagnetic guns and shells, which can realize the adjustment of the angle, and can achieve automatic serial acceleration of direct-current automatic launch of double-acceleration electromagnetic guns and shells. Bipolar or multi-stage drive electromagnetic projectiles can be fired continuously, but large-scale mechanical structures and high-end technical components are required, which cannot meet the lightweight requirements of daily teaching demonstration experiments in colleges and universities

[0004] Patent No. CN 101079195 B Chinese invention patent discloses a multifunctional electromagnetic gun demonstrator, which can realize the demonstration of various physical phenomena, such as: the principle of coil electromagnetic gun; Type (such as tube-shaped gallbladder, steel ball projectile, etc.) Accurate Measuring Device
