Definitions

  • the invention relates to a take-up shaft for a Roller blind covering a swimming pool by an engine is driven.
  • the winding shaft of the roller blind is, among other things, made of optical Often found under the water surface on the pool walls stored, the roller blind due to the buoyancy Because of its low specific weight it rises and floats on the water surface.
  • an electric motor is used, which in general is arranged on the outside of the pool. This requires complex on-site Services are rendered, for example, a Wall duct for the drive shaft of the motor in the Wall to be concreted. But above all, it's the wall penetrating drive shaft is very difficult to seal. It has therefore been proposed in a tubular electric motor install the take-up shaft designed as a hollow shaft. On however, such a tubular motor is quite expensive.
  • the object of the invention is therefore to provide a simple structure Provide a motor to drive the winding shaft of the roller blind.
  • a water-powered hydraulic motor is used for the roller blind.
  • the hydraulic motor can be constructed like a turbine be d. H. an impeller driving the take-up shaft with blades and have a stationary housing.
  • the hydraulic motor thus has a very simple structure. As water fresh water is preferably used. However, it can z. B. also circulating water can be used.
  • the impeller of the hydraulic motor provided with the blades can be rotatably connected to the take-up shaft. However, it is also possible to turn the impeller on the take-up shaft store and the take-up shaft via a reduction gear, especially to drive a planetary gear from the impeller is driven. With a normal pre-pressure of the tap water The impeller of the hydraulic motor can handle about three bars for example, 100 revolutions / minute. With the speed reduction gear can, for example can be reduced to 10 revolutions / minute.
  • the hydraulic motor preferably has two connections for supplying water to the take-up shaft in one or the other Turn the direction to wind up or unwind the blind can.
  • the reversing valve can be an electrically actuated solenoid valve that for example, operated with a switch by hand.
  • the roller blind can be wound up and unwound using the contacts on the roller blind that control the reversing valve.
  • the winding shafts used today are mostly as Hollow shafts formed. Can in the water in the hollow shaft bacteria and the like accumulate microorganisms that a considerable impairment of the hygiene of the swimming pool mean.
  • this is therefore used to drive the hydraulic motor preferably used water to rinse the hollow shaft used.
  • An accumulation of bacteria and the like This prevents microorganisms in the hollow shaft.
  • the outlet is one at the circulation system of the Basin connected suction line connected.
  • suction line can pass through the wall of the Be passed through the basin.
  • the winding shaft is preferably in the swimming pool below Water stored. According to the invention, there is no passage through the wall required for a drive shaft.
  • the invention can also be above the water surface and if necessary stored outside the pool his.
  • the roller blind floating on the water surface can be a roller shutter be or a tarp.
  • a floating tarpaulin one can Tarpaulin can be used, which has a foam core, which is covered on both sides with a waterproof film is.
  • the foam can be a polyurethane or PVC foam be the film e.g. a polyethylene film.
  • a winding shaft 3 is provided for a roller blind 4.
  • the winding shaft 3 is rotatably mounted on anchor plates 5, 6, the one on the inside of one or the other wall 7,8 of the swimming pool 1 are attached.
  • a hydraulic motor 9 is arranged to a first fresh water connection line 11 and to a second fresh water connection line 12 is connected to the hydraulic motor 9 in one or the other direction for winding or unwinding the blind 4 to be able to rotate.
  • the winding shaft 3 is designed as a hollow shaft. To them rinsing with fresh water is in the area of the hydraulic motor 9 in the hollow winding shaft 3 at least one not shown Passage opening for the inlet of the fresh water from the Line 11 or 12 provided after flowing through the hydraulic motor 9.
