First Claim
Patent Images
1. A remotely controllable robotic cannon nozzle system sized and adapted for mounting in a manway port in a storage tank containing waste sludge or material to be removed, comprising:
- a hollow mounting arm attachable to a manway or port cover on one end and having on its opposite end a pivotally mounted arm, said pivot being hydraulically powered and having on its end a second hydraulically powered pivot;
a cannon nozzle being attached to said second hydraulically powered pivot and having mounted therewith an axially aligned video camera, and an axially aligned light source;
means for supplying cleaning fluid to said nozzle under controllable pressure, the direction of said nozzle being remotely controllable by an operator, controlling the position of said first and second hydraulically powered pivots, in response to video images produced by said camera and said light source; and
an evacuation nozzle and hose means attached thereto, being remotely controllable by said operator for pumping a pumpable slurry of effluent from the tank to be cleaned.

Abstract
A cleaning system capable of passing through a manway entry point into a storage tank to be cleaned is disclosed. A remotely controllable robotic cannon for spraying diluent or water is provided which has a light source and CCTV camera axially mounted on the cannon nozzle assembly. Mounting systems permit sidewall or overhead deployment of the system as desired. Operators situated remotely can view and control the cleaning system via TV monitors.
