Definitions
- This invention relates to an apparatus for use by a diver to brush or scrape the walls of structures lying underwater of the type exemplified by ships and drilling platforms, the walls being for example curved or lying at an angle to one another, the apparatus comprising two brushes or scrapers driven for rotation in opposite directions to one another and mounted on a common frame.
- the described apparatus has a disadvantage in that the diver has to adjust the brushes independently from one another, which is of advantage in but a very limited number of conditions.
- the drawback of the apparatus is to be seen in both brushes not adjusting automatically to irregularities of those surfaces to be cleaned.
- Underwater-lying ship walls, the legs or components from drilling platforms, etc. have locally substantial irregularities or projections as well as accumulations of shell-fishes and/or seaweeds. It is frequent to encounter such accumulations in the shape of compact calcereous deposits.
- a single-sided resistance is encountered, this causes a change in those forces which act on said brushes. Due to the revolving motion of the brushes, a sidewise pressure is exerted on the apparatus.
- the invention has for an object to provide an apparatus which, due to synchronizing of the brushes and to the design of the apparatus, ensures an uniform propulsion thereof even when treating irregular surfaces, particularly when one brush encounters an obstacle which offers a . higher resistance.
- a further object of the invention is to provide an apparatus which makes possible a larger positive and negative angular displacement.
- the frame of the apparatus according to the invention comprises two major components hinged to one another by a connection which lies in that plane of symmetry of the apparatus which extends between the brushes or scrapers.
- the apparatus as shown in the figures is comprised of two frame components 1 and 2, which are connected together by a hinge connection 3, which has been shown in figures 3 and 4 by a dot-and-dash line 3.
- a brush or knife disc 4 is rotatably mounted on each frame component.
- Each brush or disc is driven by a hydraulic motor 5, even if it might be considered to drive said brushes or discs, with electric or pneumatic motors.
- the hinge 3 lies in that symmetry plane which runs through the apparatus between said frame components 1 and 2, the apparatus fits narrowly against the rounding of any curved structure 6 to be scoured or cleaned (figures 1 and 5).
- a handle 7 which extends preferably slightly slanting outwards relative to frame components 1 and 2.
- the hinge connection generally shown at 3 between said frame components 1 and 2 is comprised, in a preferred embodiment, of elements 8 and 9, the elements 9 being secured to frame component 1 and elements 8 to frame component 2.
- one element 9 is hingedly water-tight connected to an element 8.
- Lines 10, 11 and 10', 11' respectively connect the hydraulic or pneumatic motors 5 to the inlet line 12 and outlet line 13, respectively, and actually above each element set 8, 9.
- the brushes are driven by electric motors, the lines 10, 11, 10', 11' are used as tubes for electric cables.
- an operating member 14 which can control the starting as well as the stopping of the motors, by opening or closing a valve.
- a material having a high buoyancy is fastened to components 1 and 2.
- Said material is not shown in the figures, but may take any shape and extent depending on the specific weight thereof.
