Water rocket launching device and teaching aid

Abstract

The invention discloses a water rocket launching device and a teaching aid, which are used for water rocket launching teaching. The device comprises a movable rack; an adjusting mechanism is mounted on the top surface of the movable rack; the adjusting mechanism is used for debugging and mounting the water rocket; the launching mechanism is fixedly mounted on the top surface of the movable rack, and is limited in the area of the adjusting mechanism; the launching mechanism comprises a clamping piece and a releasing assembly; the clamping piece is mounted at a bottom opening of the water rocket; the releasing assembly is used for controlling installation and launching of the clamping piece and the water rocket; the gas-liquid system is fixedly mounted in an inner cavity of the movable rack; the gas-liquid system is communicated with the clamping piece through a pipeline; and the gas-liquid system is in signal interaction with the release assembly. According to the scheme, a remote full-automatic control mode is achieved technically, accurate and quantitative pressurization and water adding are achieved, the safety limit value and the safety mode are set, and the safety risk of the water rocket is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a water rocket launching device and teaching aids. Background technique [0002] The water rocket is a toy designed using mass ratio and air pressure. It is also one of the famous cases in physics teaching. It can cultivate students' interest in physics learning, and the physical principles contained in it are an important basis for understanding mechanics in physics. . [0003] At present, most of the water rocket launchers on the market are launched manually with water and gas. First, the water is manually injected, and then the gas is boosted. Finally, the bicycle brake line type launch switch is operated to launch. There are also remote control launch devices specially designed for safety. However, none of them has realized the automatic process of the whole process, and requires people to operate by the side, which has certain dangers. [0004] Therefore, need a kind...

Problems solved by technology

[0003]At present, most of the water rocket launchers on the market are manually filled with water and gas. There are also remote-controlled launch devices specially designed for safety, but none of them realize the automatic operation of the whole process, and require people to operate beside them, which is dangerous to a certain extent.
