Definitions

  • the present invention relates to the propulsion of watercrafts on a river or lake.
  • the present invention suggests a propulsion where not only the energy loss caused by the river current can be eliminated but the energy of the river current can be utilized to propel the watercraft.
  • the watercraft is propelled by wheel(s) relatively to the river or lake bottom like automobiles are propelled by wheels relatively to the road surface.
  • No energy from a motor is needed to keep the watercraft at a fixed position in a river.
  • the river current's energy can be captured by a device similar to a water turbine or water screw to generate energy to drive the craft's wheel(s). This can be the sole source of the wheel drive or additional source to the drive provided by a motor.
  • the ship's wheel(s) can be kept on the river bottom in two ways:
  • a wheeled anchor is provided as shown in figure 1 .
  • the rope or cable connecting the wheeled anchor to the watercraft is tied to the eye 3 on the input drive shaft 2 of a differential 1.
  • the torque of a motor or water turbine is transmitted from the watercraft by torsion of this rope or cable to the input drive shaft 2 of the differential 1 which transmits this torque to the wheels 4 mounted on its two output half shafts allowing the wheels 4 to rotate at different speeds while supplying equal torque to each of them.
  • the bulge shape 5 of the outer side of the wheels is preventing the anchor to lie on the river or lake bottom in a position where any of the wheels is not touching the ground.
  • the length of the input drive shaft 2 exceeds the length of the output half shafts of the differential 1 in order to have the pull of the rope or cable connecting the watercraft to the anchor turn the anchor into a position where the axis of rotation of the wheels 4 is perpendicular to the axis connecting the watercraft with the anchor. This enables the steerage of the watercraft using a classical rudder.
  • a watercraft equipped with a wheel on a pivoted fork pressed to the river or lake bottom by a hydraulic cylinder is provided.
  • the wheel 10 is mounted on a fork 9 that is connected to the watercraft 6 on each side by means of a pivot joint 8.
  • the size of the fork 9 must be sufficient to include the whole fore of the watercraft 6.
  • the barrel part of a hydraulic cylinder 7 is mounted to.
  • the piston rod of the hydraulic cylinder 7 is attached to the corresponding arm of the fork 9. The force of the hydraulic cylinder 7 thus can turn the fork 9 around the joints 8 and push the wheel 10 to the river or lake bottom 18.
  • the force that pushes the wheel 10 to the river or lake bottom 18 depends on the hydraulic pressure in the hydraulic cylinder 7.
  • This pressure can be measured and used to control the position of the fork 9 so that the wheel 10 is always pressed to the river or lake bottom with changing water depth by means of an automatic control system.
  • the force by which the wheel 10 is pressed to the river or lake bottom 18 can be selected and is limited only by the weight of the watercraft 6.
  • the pivot joints 8 on the sides of the watercraft 6 as well as the hydraulic cylinder 7 are supposed to be above water level 17.
  • the torque of a motor 11 is transmitted by a shaft 12 through the centre of one of the pivot joints 8 to a bevel gear 13 that transmits it further to a shaft 14 parallel to the corresponding arm of the fork 9. This shaft 14 then transmits the torque to the wheel shaft 16 through another bevel gear 15.
