In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a zirconium material welded protection device, is including dragging the cover shell, drag the inside top fixed mounting of cover shell to have the U-shaped inner tube, the exhaust hole has been seted up to the pipe wall equidistance on U-shaped inner tube top, and the one end of U-shaped inner tube and the fixed intercommunication of one end of intake pipe, the other end and the fixed intercommunication of external equipment of intake pipe drag the inside bottom fixed mounting of cover shell to have the wire net.

Preferably, the middle parts of the U-shaped inner pipes are fixedly connected through supporting pipes.

Preferably, the top end of the drag cover shell is fixedly provided with a handle, and the outer wall of the handle is carved with anti-skid grains.

Preferably, the diameter of the mesh of the steel wire mesh is 100 meshes.

Preferably, the air inlet pipe, the U-shaped inner pipe and the supporting pipe are all made of copper materials.

Preferably, the surface of the drag cover shell is coated with GN-20 high-temperature resistant anti-oxidation coating.

Compared with the prior art, the beneficial effects of the utility model are that:

1) in the work, the traditional drag cover shell for welding construction is reformed by matching the arranged U-shaped inner pipe, the air inlet pipe and the like, and the small-flow double air inlet of the U-shaped inner pipe is adopted to fill argon into the drag cover shell, so that the argon amount in the welding construction is ensured, and the argon using amount is saved compared with the traditional large-flow single-port air inlet method; the inside of the dragging cover shell adopts a U-shaped inner pipe which is arranged inside the dragging cover shell, and vent holes are uniformly arranged at certain intervals, so that the argon filling condition in the dragging cover shell is optimal;

2) in the work, through the steel wire mesh that sets up, owing to drag and adopt 100 mesh steel wire meshes to carry out the liner in the cover shell for gas stationary flow in the argon filling process, even, thereby make argon filling effect better among the whole welding process.
