Oh dear!  that seems quite catastrophic.
I would imagine that there is a fault in the electrical wiring that is shorting to earth.
This would be the reason the fuse has blown and why the battery is discharging rapidly.

I would take the car to an auto-electrician to diagnose the cause before any serious damage to the electrical system occurs
