Description

Device based on automatically, empty liquid in experiment

The application is divisional application with application number 2018101386816, application date 2018, month 02 and 10, title "device for automatically pouring liquid in experiment".

Technical Field

The invention relates to a mechanical structure, in particular to a device for automatically pouring liquid in an experiment.

Background

The liquid is one of three substance forms. It has no definite shape and is often influenced by the container. But its volume is constant under the environment of constant pressure and temperature. In addition, the pressure exerted by the liquid on the sides of the container is different from other physical conditions. This pressure is transmitted in all directions, not only without decreasing but also increasing with depth, which is why the deeper the water, the greater the water pressure.

And in the experimentation, often need topple over the liquid in the container, adopt artificial mode at present basically, lift up the container and then topple over it, this kind of mode intensity of labour is big, and danger is high moreover, and operating personnel judges the liquid volume that it was toppled over according to the experience, but some corrosive liquids or to the harmful liquid of human body, the mode that adopts the manual work to topple over is improper, easily causes the safety risk simultaneously, the liquid that spills or the smell that overflows can cause personnel to be injured.
