AI Technical Summary
Existing nitrogen pressurization and stabilization injection equipment is impractical when it cannot be connected to the filling equipment, and the nitrogen pressure stabilization and filling effect is not good.
A nitrogen pressurization and stabilization injection device was designed, comprising an extension component and a pressurization component. The extension component extends and stores the hose through a hose and a retractor, while the pressurization component increases the pressure inside the nitrogen tank through an electric push rod and a compression plate.
This improves the equipment's usability, enabling nitrogen injection via the extension assembly when docking is not possible, and maintaining appropriate nitrogen pressure via the pressurization assembly to facilitate subsequent nitrogen injection operations.
