Benefits of technology

[0007]The invention aims to overcome these disadvantages by proposing a new underwater vehicle for cleaning submerged surfaces, which al...

Problems solved by technology

When the hull of the boat has irregularities or differences in level in relation to the brushes, the effectiveness of the cleaning is reduced.
In addition, the thrusting of the robot against the hul...

Embodiment Construction

[0030]The vehicle 2 is provided with members for displacement comprising two pairs 6 and 7 of synchronised wheels mounted in parallel to the lateral walls 41 and 42. The pairs 6 and 7 include respectively two toothed wheels 63, 64 and 73, 74. The wheels 63, 64, 73 and 74 are driven and synchronised in rotation by the drive belts 61 and 71 about axes parallel to a transversal axis Y-Y′ of the vehicle 2, perpendicular to the X-X′ axis. The belts 61 and 71 are mounted in central grooves 700 of the external edges of the wheels 63, 64, 73 and 74.

[0031]Z-Z′ denotes an axis perpendicular to the axes X-X′ and Y-Y′ and which defines the normal to the surfaces of contact between the wheels 63, 64, 73 and 74 and a submerged surface to be cleaned, here the hull of the boat referenced as C and shown only in FIG. 7.

[0032]The invention can also be implemented to clean other types of submerged surfaces, in particular the submerged surfaces of a mast of a wind turbine located at sea, the walls of a ...

Abstract

This underwater vehicle for cleaning submerged surfaces comprises a chassis and at least one brush for cleaning the surface to be cleaned, rotationally driven by a motor about an axis of rotation of this brush, the brush being able to move, with respect to a fixed part of the vehicle, in a translational movement along its axis of rotation in such a way that it can be pressed firmly against the surface to be cleaned under the effect of a vacuum created by the rotation of the brush, the brush comprising a rotation shaft inserted into a sleeve that rotates as one with the brush and rotationally driven by a drive system, the brush rotating as one with the sleeve because of fingers fixed to the sleeve and inserted into holes of the brush with the possibility of sliding parallel to the axis of rotation of the brush.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This application claims priority benefit under 35 U.S.C. §371 to International Patent Application No. PCT / EP2012 / 062588 entitled UNDERWATER VEHICLE FOR CLEANING SUBMERGED SURFACES, and filed by inventor Sébastien Fontaine on Jun. 28, 2012. International Patent Application No. PCT / EP2012 / 062588 claims priority to French Patent Application No. 11 55805, filed by inventor Sébastien Fontaine on Jun. 29, 2011.FIELD OF THE INVENTION[0002]This invention relates to an underwater vehicle for cleaning submerged surfaces.BACKGROUND OF THE INVENTION[0003]It is known to clean the surfaces submerged in water, in particular the hulls of boats by using underwater vehicles or robots that travel along the submerged surface of the hulls, removing fouling, such as plants, minerals or shellfish, using rotating brushes.[0004]The waste is generally aspirated by a flow of water created by a turbine which also provides for the maintaining of the robot against th...
