Circulation Hero Fountain Demonstration Instrument

Abstract

The present invention relates to a circular hero of an Alexandria fountain demonstration instrument, and to the field of the teaching instrument device technology. The instrument comprises a dual-column support, a water tank is arranged between the columns of the dual-column support, a fountain is arranged at the upper portion of the water tank, and two water supply pipelines are fixedly arranged at the lower portion of the fountain; the water tank includes a first air duct pipeline, a second air duct pipeline, a first water storage cavity and a second water storage cavity, hollow first rotating shaft and second rotating shaft are arranged at two sides of the water tank, and the first and second rotating shafts are concentrically arranged and allow the water tank to rotatingly connect with the columns; the first water storage cavity is provided with a first water duct port, the second water storage cavity is provided with a second water duct port, one ends of the first rotating shaft and the second rotating shaft are respectively connected with the first water duct port and the second duct port, and the other ends of the first rotating shaft and the second rotating shaft are connected with the nozzle pool through the water supply pipeline; and the first air duct pipeline is connected with the first water storage cavity and the second water storage cavity, the second air duct pipeline is connected with the first water storage cavity and the second water storage cavity, and the first air duct pipeline and the second air duct pipeline are both provided with control valves.

Description

technical field [0001] The invention relates to the technical field of teaching instruments and equipment, in particular to a circulating Hiro fountain demonstrator. Background technique [0002] Hero is a famous scientist and inventor in ancient Greece, and his most famous invention is the fountain of Hero. The working principle of the Hero Fountain is mainly to use the water level difference between different containers to generate potential energy to compress the air, thereby driving the water to spray upward. The most intuitive effect of the Hero Fountain is that the sprayed water column can exceed At the highest liquid level, people are often surprised when they see the Hiro fountain for the first time, thinking that it violates the law of conservation of physics. In classroom teaching, it is often difficult for teachers to clearly understand the principle of Hiro fountain by verbal description alone. SUMMARY OF THE INVENTION [0003] The technical problem to be solv...

The working principle of the Hilo Fountain is mainly to use the water level difference between different containers to generate potential energy to compress the air, thereby driving the water to spray upwards. The most intuitive effect of the Hilo Fountain is that the water column ejected without external power can exceed At the highest liquid level, people are often surprised when they see the Hilo Fountain for the first time, thinking that it violates the law of conservation of physics. In classroom teaching, it is often difficult for teachers to let students clearly understand the principle of the Hilo Fountain simply by verbal description.
