Self-propelled apparatus for cleaning a submerged surface

摘要

A self-propelled apparatus for cleaning an immersed surface including a hollow body, a guiding and driving device for guiding and moving the hollow body over the immersed surface, the hollow body having a base immediately facing immersed surface, at least one liquid inlet, at least one member protruding from the base of the hollow body towards the immersed surface, wherein it includes, immediately in front of a protruding member, in a movement direction of the hollow body, at least one member, called an anti-blocking member, which can rotate about a rotation axis which is fixed in relation to said protruding member, the anti-blocking member being provided in order to be able to roll over an obstacle of the immersed surface, and to drive the protruding member in movement so as to overcome the obstacle.

主权项

1. A self-propelled apparatus for cleaning an immersed surface, comprising:
a. a body defining (i) a liquid inlet and (ii) a base; b. means for moving the body along the immersed surface in a travel direction; c. a protruding member extending from the base toward the immersed surface; d. an anti-blocking member (i) positioned in front of the protruding member in the travel direction, (ii) rotatable about a rotation axis fixed relative to the protruding member, and (iii) configured so as to be able to (A) roll over an obstacle of the immersed surface and (B) move the protruding member relative to the body in order to overcome the obstacle; and e. a common support for the protruding member and the anti-blocking member configured to be articulated relative to the body along a tilting axis substantially parallel to the rotation axis.
