Embodiment 1

[0031] A Gothenburg device without manual reset, comprising iron balls, end-to-end closed track; the track has an energy storage lifting section and an energy release falling section; the energy releasing falling section includes a high-altitude cable car device 8, a queuing and waiting device in turn , Uphill roller device 1; the high-altitude cable car device 8 includes an inlet tee 808 and an outlet tee 801, with a pair of hanging rails 804 between them, the hanging rails 804 are connected with the pulley block 806, and the cables 809 are arranged on the pulley block 806 , the car A805 is fixed on one side of the cable, and the car B803 is fixed on the other side. The cars A and B move in the opposite direction with the cable; there is a three-way door 807 at the position of the entrance tee, and the iron ball enters one of the entrance three-way doors Finally, the three-way door turns, closes this door, and opens another door; the iron ball enters the car A, drives the car ...

Embodiment 2

[0045] The difference from the first embodiment is that the side plates 2 on both sides of the drum are made of a material with adjustable transparency.

[0046] The present invention lifts the stored energy through the lifting section of the energy storage, and releases the energy through the falling section of the energy release section, so that it can run reciprocatingly without stopping; it can perform interesting demonstrations of physical principles such as the conversion between potential energy and kinetic energy, and automatically The effect of teaching demonstration is good; it is easy to arouse people's curiosity and entertaining; the drum and its inner spiral track are designed cleverly, and the drum is equipped with transparent side panels and opaque cover plates, which is conducive to improving the effect of teaching demonstration The structure is simple, and the design of the car is ingenious; the inertia of the iron spheres is used to set each iron sphere to equ...

Abstract

The invention relates to a goteborg device without need of manual resetting. A track is provided with an energy storage lifting section and an energy release falling section, wherein the energy release falling section comprises a high-altitude cable vehicle device, a queuing up device and an uphill rotary drum device in sequence; the slope of the uphill rotary drum device is provided with a rotarydrum capable of rolling along the slope; a spiral track is arranged inside the rotary drum; a center hole is formed in the center of the side wall of the spiral track; an iron ball enters the centerhole and rolls under the action of the gravity along the spiral track so as to drive the rotary drum to roll upwards along the slope; during the rolling, the physical gravity center of the whole of the iron ball and the rotary drum is lowered; the front section of the slope is an uphill section, and the rear section of the slope is a downhill section; the iron ball just enters the downhill sectionwhen leaving the rotary drum from the tail end of the spiral track; at the moment, the rotary drum goes backwards to the initial position along the uphill section under the action of the gravity to wait for the next iron ball. The goteborg device without need of manual resetting can make a relatively good interesting demonstration of physical principles such as conversion between potential energyand kinetic energy, is relatively good in automatic teaching demonstration effect, and can easily arouse the curiosity of people, so that people are taught through lively activities.

Description

technical field [0001] The invention relates to an automatic physical demonstration device, in particular to a Gothenburg device without manual reset. Background technique [0002] The Gothenburg device is a sophisticated and complex piece of machinery that uses twists and turns to accomplish some very simple tasks, and is popular for its playfulness. The Gothenburg device can be designed with multiple links, and each link contains various simple mechanical principles, such as levers, pulleys, collisions, etc. Through continuous motion transmission, the action of the next link is continuously triggered, and a certain job is finally completed. [0003] Most of the existing Gothenburg installations are disposable. After each demonstration, it is a "ruin". If you want to demonstrate again, you have to rebuild and reset. It is time-consuming and labor-intensive, so it is not suitable for exhibition hall display. In addition, the existing Gothenburg device pays more attention ...
