Abstract

The invention relates to a physics teaching tool, in particular to a water injection and air inflation integrated water rocket launching device. The device solves the problems that the center-of-gravity position of the existing water rocket is unstable, the flying attitude in launching is inconsistent with the pre-designed flying attitude and has relatively great error and consequently the experimental effect is influenced. The upper end of a first pipeline sequentially penetrates through a launching pad and a water sleeve and is arranged in the water rocket body and located at the upper part of the water rocket body; the lower end of the first pipeline is communicated with the lower end of a second pipeline and one end of a third pipeline through a tee joint respectively; the upper end of the second pipeline is communicated with the lower end of a funnel; the second pipeline is provided with a first valve; the other end of the third pipeline is communicated with one end of a fourth pipeline; and the fourth pipeline is provided with a second valve and an air needle respectively. The device disclosed by the invention is applied to physics teaching.

Description

technical field [0001] The invention relates to a physics teaching tool, in particular to a water-injecting and air-filling integrated water rocket launching device. Background technique [0002] Most of the current water rocket launching devices are made by installing an air needle on the base of the water-through sleeve, and directly inflate the air needle with an air pump. There are three problems in the use of this launching device: 1. When launching, the water rocket must be Put it upside down, inject the specified amount of water into the bottle, and then insert the water rocket nozzle into the water sleeve to lock it. This process will cause water to flow out of the rocket body. If it is a multi-stage water rocket, it will cause water to flow into the bottom. In the above rocket body; 2. For multi-stage water rockets, when the rocket body is pressurized, the water in the bottom bottle will be brought to the upper bottle by the air filled in and cannot be left behind, ...
