This is the content of traditional Chinese medicine in middle school physics teaching. However, there is no equipment for demonstrating hydraulic launch experiments in middle school physics teaching. Therefore, learning 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 demonstration apparatus for water pressure reflection experiments

The invention relates to the field of teaching appliances, and particularly relates to a demonstration instrument for a water pressure reflection experiment. The demonstration instrument comprises a water storage container. One end of the water storage container is provided with a launching mechanism and an angle adjusting mechanism for adjusting the injection angle. The launching mechanism comprises a stand plate which is fixed on one side of the water storage container and an energy storage mechanism which is hinged on the other side of the water storage container through pin shafts. A wrench is articulated on the stand plate, and the energy storage mechanism is connected with the wrench. An ejection assembly is arranged at the upper end of the wrench. The ejection assembly comprises a clamp plate which is fixed on the upper end of the wrench and an ejection member which is inserted on the clamp plate. According to the demonstration instrument for the water pressure reflection experiment, the ejection member is ejected to the water surface along the tangential direction of the movement track of the end of the wrench under the action of the inertial force and reflected out according to the rebound effect of water, and the length of the pull rod can be adjusted to adjust the elastic size of the spring and then different initial speed can be obtained so that the experiment process is highly interesting and the students' interest can be improved, and the students are enabled to feel the existence of water pressure more intuitively and understand the knowledge.
Description
technical field [0001] The invention relates to the field of teaching appliances, in particular to a demonstration instrument for water pressure reflection experiments. 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 the content of traditional Chinese medicine in middle school physics teaching. However, there is no equipment for demonstrating hydraulic launch experiments in middle school physics teaching. Therefore, learning 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 demonstration apparatus for water pressure reflex experiments. Contents of the invention [0003] The purpose of the present invention is to provide a demonstration instrument for wat...
