Definitions

  • the invention relates to a turf installation for generating an artificial water wave according to the preamble of claims 1 and 1.
  • the shaft systems described here are suitable not only for mobile, but above all for stationary use with increased reliability requirements.
  • wave surfing develops a strong attraction for many water and recreational athletes.
  • the surfer uses the formation of waves in a liquid, which is typically water.
  • the wave must therefore be suitable to carry the surfer on a surfboard. It is therefore a standing wave.
  • the surfer can ensure his stay on the wave or the wave crest.
  • the surfer is typically dependent on suitable conditions prevailing in natural moving waters, such as rivers or the open sea, which allow the formation of waves. These waves can then be used for surfing. Depending on the boundary conditions, these are either standing waves, such as in rivers or canals with barrages, or even running waves, such as in the open sea.
  • the pumps for conveying the liquid including its electrical components are in the same water as the surfer.
  • the electrical components themselves are equipped with the usual electrical insulation.
  • it comes here to a malfunction or damage to the insulation there is the risk of life-threatening injury from electricity for the surfer mainly because of the conductivity of the walls of the pool, but also the water.

  • At least one electrical component preferably at least one electrical device or at least one electrical component of the at least one feed pump, in the region of the conveying path between the outlet and inlet of the wave pool.
  • the shaft system is characterized in that a wall-side electrical insulation of the conveying path between the at least one arranged in the liquid electrical component and the wave pool is provided. This ensures that an additional electrical insulation of a surfer on the shaft or in the liquid takes place with respect to the electrical components in the water. This is particularly important in the event that, for example, a malfunction of an electrical component, such as a pump, is present, so that the liquid comes into contact with an electrical conductor of the pump.
  • the insulation is provided over a distance of a few meters, preferably about 1 to 10 m, in particular about 5 m. So a safe isolation against electric current can be achieved.
  • the water located in the basin conducts the electrical current comparatively poorly over such a distance, so that there is virtually no danger to a person in the water.
  • a wall region of the conveying path and / or of the at least one basin is electrically insulated. Further preferably, this is done at least in sections, so preferably as at least one wall section of the conveyor line and / or the at least one basin. Thus, the conduction of electrical current via the respective wall surface is preferably prevented.
  • an uninterrupted electrical insulation is provided over the entire cross section of the conveyor line.
  • the conveyor line is isolated over the entire cross-section, which can come into contact with the liquid.
  • the insulation is thus completely in an at least partially closed, for example, breakthrough conveyor line. This can be the case over the entire conveyor line or only in a section of the same. Thus, no electricity can be conducted along the conveyor line.

  • the conveying path in particular the wall of the conveying path, at least partially formed of an electrically insulating material, preferably at least substantially.
  • the conveyor section or sections thereof can consequently be designed to be electrically insulating at least completely or at least in preferably essential parts. Thus, no additional material or no additional processing is required to achieve the electrical insulation effect.
  • a plate-shaped material and / or layer material is preferably provided. Such material can be easily manufactured and processed. In particular, this makes it possible to equip entire surfaces for the production of electrical insulation with likewise plate-shaped material.
  • the plates can be flat and / or curved, in each case over the entire surface or in sections. This achieves adaptation to the circumstances.
  • a plastic material is provided as electrically insulating material. It is further preferably a Plastic coating and / or at least one plastic plate.

Preferably, at least 2 m are isolated, which also complies with the applicable standards for electrical insulation. This can be provided uninterrupted or in sections.
  • the insulation can in particular also be composed of several sections, preferably in the manner of a section-wise isolation. This can be caused for example by the structural or technical conditions. Thus, several sections of the insulation of the wall together meet the requirements of sufficient isolation overall. The stated lengths can therefore apply to individual sections or the entire section.
  • the above-mentioned object is also achieved by a wave system for generating an artificial water wave for surfing with the features of claim 11.
  • the wave system has in the preamble to the features described in claim 1 above.
  • the shaft system claimed here is characterized in that the at least one electrical component is arranged spatially separated from the fluid. Preferably, it is a structural separation. This means that the at least one electrical component can not come into contact with the liquid. Conversely, no electrical energy or no electric current from the electrical system or the electrical component can be delivered to the liquid. A risk to the surfer by electricity is thus excluded, especially in case of failure. Due to the construction of the known wave systems, this is by no means obvious.

  • the separate conveyor line ensures a particularly targeted and loss-free promotion.
  • the pumps for generating standing waves due to the required high throughputs are mounted directly in the pool including the electrical equipment.

  • the inlet 20 is arranged for this purpose in the main basin 18, in particular below the water level.
  • a ramp 22 is shown, via which the water 13 is conducted into the actual wave basin 11. Because of under a shallow Angle obliquely downwardly sloping ramp 22 typically develops an admittedly accelerated but rather essentially laminar flow of the liquid 13. At the right-hand end region of the wave pool 11 there is a drain 23 for the water 13. Through this drain 23 through the water 13 can flow back into the main basin 18.

This conversely, however, at the same time avoids that, even in the quiescent state, a significant amount of water 13 is still present in the wave basin 11, which may need to be monitored and possibly cleaned. Since the amount of water pumped by the pumps 15 is relatively large compared to the outlet 23, a certain amount of water 13 will be permanently present in the wave tank 1 1 in the operating state.
