Definitions

  • the invention relates to a bottom sampler for the underwater collection of bottom material in a water course and for raising this material subsequently above the surface.
  • the bottom material so collected is used for morphological analysis in connection with the water course to be studied where the composition of the bottom material has to be known.
  • the sample can be used for an evaluation of environmental aspects associated with the composition of the bottom material.
  • the bottom sampler comprises a shovelling bucket, made of an impact-resistant material such as sheet steel and provided with two slide rods mounted on both sides of the bucket, a number of holes in the sides of the bucket, a cover plate for sealing these holes, a construction made up of a tongue with chains or cables by which the bucket has been suspended with the aid of the slide rods, and a drag chain or cable.
  • a shovelling bucket made of an impact-resistant material such as sheet steel and provided with two slide rods mounted on both sides of the bucket, a number of holes in the sides of the bucket, a cover plate for sealing these holes, a construction made up of a tongue with chains or cables by which the bucket has been suspended with the aid of the slide rods, and a drag chain or cable.
  • the bottom sampler comprises a shovelling bucket 1 made of sheet steel, provided on both sides with iron strips 2 which the drag chains 3 are attached.
  • a number of holes 4 have been drilled through the sides; these holes can be sealed by means of cover plates not shown in the drawing.
  • At the open end of the bucket 1, its bottom is provided with steel teeth 5.
  • the slide rods 6 along which the suspension chains 7 can move between points 9 and 10 have been mounted on both sides, a small distance away from them and parallel to them.
  • the slide rods slope up from the rear to the front of the bucket 1.
  • the bucket 1 is provided with a carrying bracket (14) which also acts as protective bracket.
  • the drag chains 3 can be attached to a tow rope 15.
  • the bottom of the bucket may, if desired, be reinforced on the underside with a number of ski-type strips 16.
  • the bottom sampler according to the invention is operated in the following manner. Through the hoisting cable 13, the bottom sampler is connected to the winch of a ship's deck crane or davit. Then, the bucket 1 is lowered horizontally to the water surface by releasing the drum of the winch and allowing the tow rope 15 to unwind slowly. When the bucket 1 has reached the bottom of the water course, the tow rope 15 is paid out over a distance of about 25 metres. The end of the tow rope 15 is then secured to one of the ship's bollards, whereupon the ship starts moving slowly upstream. The combined weight of the bucket 1 and the drag chain 3 causes the bucket to eat its way into the bottom with its teeth 5, so that it becomes completely filled.
