An interesting teaching and demonstration tool for physical water pressure

Abstract

The invention relates to the field of teaching tools, and specifically relates to an interesting teaching demonstration tool of the physical water pressure. The interesting teaching demonstration toolcomprises a water storage container equipped with water, one end of the water storage container is provided with an emitter, the emitter comprises a rotating disc supported above the water storage container through a support, the center of the rotating disc is slidingly plugged with a pull rod, a slot is fixed to a ring surface of the rotating disc, an ejection member is plugged in the slot, andan angle adjusting assembly is fixed at one side of the emitter and located on the water storage container. According to the interesting teaching demonstration tool of the physical water pressure, therotating disc is driven to rotate rapidly through puling of a twisted rod, the rotating disc provides an initial emission speed for the ejection member through the slot, when a stopping lever touchesa stop block, the ejection member is ejected into the water surface due to inertia and reflected according to a rebound effect of water, the angle of the ejection member ejected into the water surface can also be adjusted through the angle adjusting assembly, the interestingness of an experiment process is high, the interest of students is improved, the students can feel the existence of the water pressure more visually, and the students are helped to understand knowledge.

Description

technical field [0001] The invention relates to the field of teaching appliances, in particular to an interesting teaching demonstration appliance for physical water pressure. Background technique [0002] Water is a common fluid substance in nature. When a foreign object is shot into water at a certain angle and speed, the water will exert a certain reaction force on the object and reflect the object. This is an important content of middle school physics teaching, but at present there is no equipment to demonstrate the hydraulic launch experiment in middle school physics teaching, so the promotion is only in the imagination stage of theoretical analysis, which is not conducive to students' deep intuitive understanding and memory of it , in view of this, we propose a kind of physical water pressure interesting teaching demonstration appliance. Contents of the invention [0003] The purpose of the present invention is to provide a physical water pressure interesting teach...
