Koch football device

Abstract

The invention discloses a Coriolis football device which comprises a base, a power system, a penalty kick system, a football supply circulating system and a power supply system. The power system, the penalty kick system, the football supply circulating system and the power supply system are arranged on the base, and the power supply system is respectively and electrically connected with the power system, the penalty kick system and the football supply circulating system. The power system comprises a motor and a transmission mechanism, the penalty kick system comprises a shooting device for shooting a football and a goalkeeper device, and the shooting device comprises a transmission device and a shooting tube. The foot supply circulating device comprises a football collecting device and a football lifting device. The football collecting device comprises a shifting fork used for collecting the shot football, a hopper and a hose. The power system is connected through a coupling, the centering performance of the components is good, mechanism movement is smooth, and the power transmission efficiency is high. Circulating continuous shooting is facilitated through an electromagnet applied in the penalty kick system, the system response is rapid, and a master can experience the football shooting movement smoothly. The enjoyment is increased due to the fact a goalkeeper in front of a goal moves back and forth.

Description

technical field [0001] The invention relates to a scientific football device, in particular to the exploration of Coriolis force when the implicated motion is rotation, and belongs to the experimental teaching aid of kinematics. Background technique [0002] At present, there are already some demonstrators on the market that demonstrate the existence of Coriolis force. For example, the patent publication number is CN202003547U, and the announcement date is 2011.10.05. The patent name is the Chinese utility model patent of Coriolis force demonstrator. It is to place a single pendulum swinging vertically on a horizontally rotating ball. When the pendulum swings and the ball rotates horizontally, the swing trajectory of the single pendulum will change at this time to reflect the Coriolis force. [0003] The existing demonstrator reflects the existence of Coriolis force to a certain extent, but there are many defects, as follows [0004] ① The reason for the existence of Coriol...

AI Technical Summary

Problems solved by technology

[0004] ① The reason for the existence of Coriolis force cannot be well demonstrated;

[0005] ②The factors affecting Coriolis force cannot be well demonstrated;

[0006] ③The structure is simple and has no novelty;

[0007] ④ Lack of interactive links, not interesting;

[0008] ⑤ Obvious experimental phenomena cannot be seen;

[0009] Therefore, there is currently no good demonstration organization to meet the learning requirements of students, resulting in many students learning this knowledge point by rote memorization or tactically, and teachers can only rely on PPT explanations in class. Students and teachers who understand can only repeat it a few times
