Definitions

  • the invention relates to a device for the removal of growths on constructions of several origins, which are under the sea water level, such as pilars and other supports of artificial islands for oceanographic investigation and for the winning of raw materials, comprising drilling platforms as well as pipe lines etc.
  • the device described therein has appeared to be particularly appropriate for the removal of crustaceans and other growths from constructions used for the support of artificial islands as well as from floating constructions. It is characterized by a flexible sheet upon which two or more shields are mounted, upon each of which a driving mechanism is attached, which by means of conduit pipes pneumatically or hydraulically can rotate a driving shaft which is perpendicularly mounted upon said flexible sheet and upon which different mutually exchangeable bearing devices with scrubbing means can be fastened.
  • any profiles, elevations etc. can be scoured off.
  • the flexible sheet can be moved around bent curved surfaces.
  • the scrubbing means the growths are removed effectively while no damage of the construction can take place, such as that which is likely to appear by removal of growths with linearly applied hand tools, such as chisels, mallets etc.
  • knives, bristles, teeth and/or scouring cushions are used as scrubbing means.
  • the novel pneumatically or hydraulically driven apparatus is characterized according to the present invention in that exchangeable circular discs, to be affixed on the driving shaft, are provided with steel chisels or plain-iron cutters placed in a secant configuration with respect to the circumference, the horizontal axis of said chisels or cutters having an angle of 30 0 towards the radius of said discs.
  • Preferably six or more of said chisels are fastened in this way upon the circular disc of the scouring device.
  • the material and the shape of said chisels are selected according to an assortment, which gives the choice dependent on the kind of the surface to be cleaned and in particular on the nature of the growths to be removed, which may vary from coralline, shell valves, mussels, seaweed, algae, corrosion, to tectonic and chemical crusts and filthiness.
  • this consists of a circular disc upon which rectangular elements or means are welded which are square in cross-section, and which are bevelled along one of the oblong edges in the shape of a chisel.
  • the invention is further elucidated on the basis of the enclosed figures 1-5.
