The sematosensory interaction Bernoulli balance ball presentation device has the advantages that the design structure and overall arrangement are reasonable, swing at a certain angle can be achieved by arranging the rotating mechanism and an airflow volume control device at the lower end of a generating airflow control device, the control adopts a sematosensory mode, and the interactivity and interestingness are increased.
Description
Technical field
The present invention relates to science popularization or demonstration physics principle technical field, specifically belong to the interactive Bernouli balance ball demonstrator of a kind of body sense.
Background technology
Effort balanced ball is demonstrated, and after the ejection of flow shedding pipeline, must form the core space that a flow velocity is higher, and a flow velocity is the free boundary layer of zero.Fluid stagnation pressure be by dynamic pressure and static pressure dimerous.In fact it represent kinetic energy and the pressure potential energy of fluid.According to energy conservation, bernoulli is reached a conclusion: when ideal fluid is along its stream line motion, and stagnation pressure keeps constant constant.In other words, high in the core space speed of air-flow, static pressure is low; Otherwise, low in the marginarium speed of air-flow, static pressure is high.If a spheroid departs from flow middle district, external and internal pressure difference will promote spheroid and return core space.Although existing Bernouli balance ball demonstrator make use of bernoulli theorem, stable for spheroid is suspended in the air, but it is, by the steel-wire track tilted, ball is passed to next spout, and utilize tilting spout or manual corrugated tube that ball is dropped into blue circle, its demonstrating effect is poor, nowadays in each science and technology center and the occasion such as each science popularization venue and teaching demonstration, about the equipment of bernoulli balanced ball demonstration, mostly more single, uninteresting, the interest of participant's active testing can not be caused.
Summary of the invention
For the problems referred to above, the object of this invention is to provide the interactive Bernouli balance ball demonstrator of a kind of body sense, overcome the deficiencies in the prior art, project organization, rationally distributed, spectators pass through gesture, guide the floating of bead, rotating mechanism and air flow rate, current velocity controller is provided with in the lower end of air-stream generating device, the dull mode of motion of existing bead can be changed, can make bead in the certain limit of area of display, interactive with experiencer, also can be implemented in the swing of certain angle, control to adopt physically sensitive mode, increase interactive and interesting.
The technical solution used in the present invention is as follows:
