Coriolis football device

Abstract

The invention discloses a Coriolis football device, which comprises a base, a motive power system, a penalty kick system, a football supply circulation system and a power supply system, wherein the motive power system, the penalty kick system, the football supply circulation system and the power supply system are arranged on the base, the power supply system is respectively connected with the motive power system, the penalty kick system and the football supply circulation system, the motive power system comprises a motor and a transmission mechanism, the penalty kick system comprises an emitting device and a goalkeeper device, the emitting device is used for emitting footballs, and comprises a transmission device and an emitting tube, the football supply circulation device comprises a football collecting device and a football lifting device, the football collecting device comprises a pulling fork, a funnel and a hose, and the pulling fork is used for collecting the emitted footballs. The Coriolis football device has the advantages that the motive power system adopts a shaft coupler for connection, the centering performance of each component is good, the movement of the mechanism is smooth, the motive power transmission efficiency is high, an electromagnet used in the penalty kick system is favorable for realizing the circulated continuous emission, the system response is fast, a controller can smoothly experience the foot shooting action, and the interestingness is enhanced through the to-and-fro movement of goalkeepers before goals.

Description

technical field [0001] The invention relates to a Coriolis football device, in particular to the exploration of Coriolis force when the implicated motion is rotation, and belongs to kinematics experimental teaching aids. 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 Coriolis force...

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
