Description

TECHNICAL FIELDThe present invention relates to a pond system for use as swimming pool and bathtubs, wherein the swimming pool system comprises a swimming pool as primary pond and a regenerating pool as secondary pond. Between the primary pond and the secondary pond there is arranged an overflow with a filter basket, over which water flows from the primary pond to the secondary pond. The system further comprises a conduit for recycling the purified water from the secondary pond to the primary pond. A separate cistern is associated with the swimming pool system for storing water which can be conveyed into the swimming pool system if required.PRIOR ARTSwimming pools as an alternative to swimming pools are known in different designs.DE 103 05 468 A1 describes a swimming pool which is divided by a partition into at least one first region, for example a swimming region, and into at least one second region, wherein the second region is designed as a filtering and cleaning region with at least one layer of a particulate filter material. Water is removed from the first region via a water circuit enclosing the particulate filter material and, after passing the filter medium of the second region, is fed back to the first region via water outlet openings. A disadvantage of this system is the high technological outlay required for the purification of the water.DE 101 28 930 A1 discloses a pond system which has a primary pond which can be used as a swimming pool and bathing pond, and a secondary pond which is provided for cleaning primary pond water. The secondary pond is connected to the secondary pond via an overflow, wherein surface waves generated by a wave generator in the primary pond can slosh into the secondary pond via the overflow. Purified water is pumped back from the secondary pond into the primary pond via a return line and a circulation pump. The water is purified via a drain base filter which is arranged in the middle of the secondary pond.WO 2008 / 096010 A1 relates to a water basin installation having a first water basin, which is suitable for bathing or swimming, and a second water basin, in which the water from the first water basin is processed. The water from the second water basin is transferred by means of an air pump as a driving device via at least one transfer line into the first water basin, wherein a water circuit is formed.The Austrian patent application AT 503 065 A2 describes different basin composite arrangements which comprise at least one swimming pool, at least one filtering basin and, according to an advantageous embodiment, at least one additional basin which is designed as a second filtering basin and / or as a compensation basin. The respective basins are connected to each other via different delivery lines and water supply devices, wherein the delivery lines and water supply devices are regulated by means of delivery means in combination with blocking means, valves, three-way valves, level controllers, blocking and / or throttling means.DE 10 2006 018 710 B4 discloses a pond system having a primary pond, a secondary pond, an overflow device arranged between the primary pond and secondary pond, and a return line via which water can pass from the secondary pond to the primary pond by means of a circulation pump. The pond system is combined with a cistern which is provided as a water store for rainwater for refilling the pond system. The filling of the pond system is regulated by at least one level sensor arranged in the cistern, which is connected to a switching device which controls a pump arranged in the cistern, a return line leading to one of the ponds being connected to the pump, via which return line the pond system can be filled to the desired level.The arrangement described in the above-summarized document has the disadvantage that the adjustment of the water level in the pond system takes place indirectly via the at least one level sensor arranged in the cistern in a standpipe connected to the regeneration pond via a pipeline, which-as has shown practical experience-leads to inaccuracies and delays in the leveling of the water level due to the filter resistance.In addition, the above-described installation has the disadvantage that the return of the purified water using a pump arranged in a separate pump shaft is very complicated in terms of design, wherein, in addition, in the return described in the above document, there is no possibility of removing sediments which can settle out from the water circuit during a relatively long standstill of the swimming pool system (for example in winter) during the re-operation.It is therefore the object of the present invention to improve the pond system described in the last-mentioned document and to provide a swimming pond system in which the above-mentioned disadvantages are eliminated.SUMMARY OF THE INVENTIONThe object is achieved by a swimming pool system according to claim 1.The pool pond system according to the invention comprises a pool pond as primary pond, a regeneration pond as secondary pond, wherein between the primary pond and the secondary pond an overflow with a filter basket is arranged, via which water can pass from the primary pond to the secondary pond, a line for returning the purified water from the secondary pond to the primary pond, wherein a separate cistern for storing water, which can be conveyed into the pool pond system if necessary, is associated with the pool pond system. In this case, a measuring sensor for checking and setting the level of the swimming pool system is arranged in the region of the regeneration pool, wherein the measuring sensor is operatively connected via a control line to a low-voltage pump arranged in the cistern.An advantageous embodiment of the pool pond system provides that the sensor is an optical sensor and is arranged in the area of the regeneration pond in a pump shaft equipped with a low-voltage pump provided as a circulation pump for the return of the purified water from the regeneration area into the primary pond. In this way, the level of the purified water is measured directly in the regeneration pond, which has the advantage that the desired water level can be set very quickly via the control line in combination with the low-voltage pump in the cistern, whereby a smooth and safe operation of the swimming pond can be ensured.The primary pond is cleaned according to the same principle already known from the prior art, wherein the water-polluting particles on the surface of the primary pond, the level of which is higher than that of the secondary pond, are transported away by generating waves for overflow between the primary pond and the secondary pond and are rinsed via the overflow into the lower secondary pond. On the side of the secondary pond, a filter basket is arranged below the overflow, in which the coarser particles are collected.In a further advantageous embodiment of the present pool pond system, the line for returning the purified water from the secondary pond to the primary pond has a bypass which is arranged in a shaft and comprises a shut-off cock and an arrangement for water flushing, wherein the bypass is provided for slurrying out sediment particles which settle in the regeneration region during a relatively long standstill of the pool pond system. This embodiment is particularly useful when the pool pond system is not used permanently, but longer standstill periods are also provided, for example in winter.The bottom and side regions of the swimming pool and of the regenerating pool are preferably sealed towards the outside with a continuous seal comprising the entire swimming pool system and made of pond foil and fleece. This embodiment has the construction advantage that the entire swimming pool system can be sealed with a single upstream construction measure. Alternatively, finishing basins can also be used.The regeneration pond itself is divided into a surface pond area and an underlying regeneration area, wherein the regeneration area is constructed from a sand layer arranged on a stainless steel screen as a filter and cleaning layer and an underlying rolling gravel layer, which extends up to the sealing of the regeneration pond and is offset with at least one drainage line.The pump shaft equipped with the low-voltage pump is arranged vertically in a side region of the regeneration pond, wherein its starting point lies above the surface of the surface pond region. The pump shaft then leads through the surface pond region, the sand layer and a sealed passage in the stainless steel screen into the rolling gravel layer, where the pump shaft is advantageously operatively connected to the drainage pipe, so that the shaft is filled exclusively with purified water from the regeneration region. The end point of the pump shaft extends as far as the seal of the pond system which forms the bottom of the regeneration pond. Alternatively, the end point of the pump shaft can also be arranged so far above the seal that the pump shaft, in the lower region of which the low-voltage pump is arranged above the seal, is filled with the regenerated water without problems.A further advantageous embodiment of the swimming pool system provides that the rolling gravel layer offset with at least one drainage line has two separate drainage pipes and is divided by means of a partition into a pump region with a pump shaft and circulation pump and a cistern region, wherein the partition is preferably formed from concrete curbstones. In an advantageous embodiment, the drainage pipe in the pump region forms a closed circuit into which the pump shaft is integrated, while the drainage pipe in the cistern region is closed at its one end in the regeneration region by a closure cap and at its other end leads via a flange to an external pipe leading to the cistern.The purified water from the cistern region can advantageously be introduced into the cistern via a pipe connection fastened with a flange, the pipe connection opening into a standpipe which is arranged vertically in the cistern and is closed at its end pointing towards the base of the cistern and the upper outlet opening of which is arranged at a height which is at or slightly above the normal level of the regeneration pond.By dividing the regeneration region into a pump region and a cistern region, the sand filter layer above the cistern region is loaded less than the sand layer above the pump region, in which the regenerated water is permanently circulated and returned to the primary pond. The less heavily loaded and correspondingly more continuous sand layer above the cistern region ensures that, for example in the case of heavy rain, the water is discharged sufficiently quickly from the regeneration pond into the cistern and overflow of the pond system is prevented.Preferably, the low-voltage pump arranged in the cistern is operatively connected to a pipe which ends above the ground above the regeneration pond for refeeding the regeneration pond, so that, when the water level is lowered, purified water can be pumped from the cistern into the regeneration pond.The entire swimming pool system can be advantageously replenished with the aid of at least one external rainwater line, wherein the replenishment is preferably effected by introducing the rainwater into the regenerating pool. The excess rainwater is then collected in the cistern after the cleaning step in the regeneration pond and, if required, returned to the water circuit again. The replenishment via the regeneration pond has the advantage that in this way a direct compensation of the level is effected, since the sensor is likewise arranged in the regeneration pond. The refilling can of course also take place via the swimming pool or indirectly by introduction into the cisterns.An overflow of the pond is prevented by providing an emergency overflow in the cistern in which the excess water is collected, which is arranged below the level of the upper outlet opening of the standpipe, so that an overfilling of the cistern, which would result in a pushing back of the water into the regeneration pond and thus an overflow of the swimming pond system, is prevented. The excess water can be discharged via the emergency overflow into the sewer system, a drain pit or into the groundwater.In view of the high water costs, it is of course expedient to make the size of the cistern dependent on the average amount of rainwater to be expected, wherein it is to be taken into account that excess water from the cistern can optionally also be used elsewhere.DESCRIPTION OF THE DRAWINGSThe different exemplary features described above can be combined with one another according to the invention, provided this is technically expedient. Further features, advantages and embodiments of the invention will become apparent from the following description of the figures, with which the proposed swimming pool system is explained in detail on the basis of selected examples. It is understood that these examples are by no means intended to be limitations, but merely serve to explain the basic principle of the present invention.The figures used for explanation show: FIG. 1 shows a schematic illustration of the swimming pool system in cross section; and FIG. 2 shows a schematic illustration of the pond system in plan view.FIG. 1 shows the pool pond system according to the invention in cross section, wherein a plurality of cross-sectional planes have been extracted and are reproduced in a drawing in order to better understand the diagram of the pool pond system.The pool pond system essentially consists of a primary pond 1, which is provided as a pool or bathtub, and a secondary pond 2 for cleaning and regenerating the water, which flows from the primary pond 1 into the secondary pond 2 via an overflow 3 mounted on a foundation 35. In order to achieve a water circuit, the purified water is returned from the secondary pond 2 to the primary pond 1 via a line 5 using a circulation pump 10 and is introduced into the primary pond 1 at the end of the primary pond 1 opposite the overflow 3 using an outflow opening 39, which is arranged at a sufficient drop height above the water surface of the primary pond 1, where a surface source 34 is formed. The wave movement which occurs at the source 34 has the effect that the contaminants floating on the water surface are washed to the overflow 3 and transported via the overflow 3 into the lower secondary pond 2. There, the coarser dirt particles are collected in the filter basket 4, which is arranged directly following the overflow 3 in the secondary pond 2, and can be removed from the pond system by emptying the filter basket 4, which is suspended on the overflow 3. The floor of the primary pool 1 is designed in the present case with floor plates 36, which are mounted in split on the seal 16, wherein the loading of the floating pool floor is not absolutely necessary, since this is primarily an optical configuration.The regeneration pond 2 can be divided into a surface pond area 17 and a regeneration area 18, wherein the regeneration area 18 consists in layers of a sand layer 19, which adjoins the surface pond area 17 and forms virtually its bottom, a stainless steel screen 20, on which the sand layer 19 is mounted, and a roller gravel layer 21, which is offset by drainage pipes 22 and extends from the stainless steel screen 20 to the seal 16 forming the outer skin of the swimming pond system. In the regeneration pond 2 a vertical pump shaft 11 is arranged, the starting point 23 of which lies above the surface of the water, while the end point 24 extends up to the seal 16 in the rolling gravel layer 21, wherein an opening with an exact fit and correspondingly sealed is present in the stainless steel screen 20 as a passage for the pump shaft 11. In the lower end of the pump shaft 11 there is arranged a low-voltage pump 10, which is provided as a circulation pump and is in flow connection with the line 5 for returning the purified water into the primary pond 1. The line 5 leads laterally in the ground past the regeneration pond 2 and swimming pond 1 to the end of the swimming pond 1 opposite the overflow 3 and there ends in the front region of the swimming pond 1 above ground at a sufficient height above the water surface of the swimming pond 1 with an outlet opening 39. during swimming operation permanently purified water, which accumulates in the pump shaft 11, is conducted via the line 5 back into the primary pond 1, wherein, as a result of wave formation and flow in the region of the source 34, permanently purified water is conducted via the circulation pump 10, where the purified water is fed back into the primary pond 1, the impurities present on the water surface are conveyed to the overflow 3 and are collected in the filter basket 4.In order that sufficiently purified water can collect in the pump shaft 11, this is advantageously in flow connection with the drainage pipe 22, which, however, cannot be seen in the selected sectional illustration in FIG. 1, but is evident when viewed together with the plan view from FIG. 2.An advantage of the present invention compared to the prior art results from the fact that a bypass 12 is integrated in the line 5, which bypass comprises a shaft 13, a shut-off cock 14 and an arrangement 15 for water recirculation. The bypass 12 offers the possibility of cleaning the system after a standstill of the floating operation, in which contaminants can settle out, before the system is again transferred to continuous operation. In this case, the return flow into the primary pond 1 is stopped by closing the shut-off cock 14 and the contaminated water is discharged from the swimming pond system via the arrangement 15 for water recirculation and can become ice in the shaft 13, which simultaneously allows access to the shut-off cock 14 and the arrangement 15 for water recirculation.The crop region of the regeneration pond 2 is designed as a zone 37 planted with water plants or soil plants, whereby a natural biological water treatment is additionally promoted. In the present case, a simultaneous planting of the crop region of the primary pond 1 has been dispensed with, which would likewise be feasible without problems, however, without impairing the operation of the swimming pool system.In the advantageous embodiment of the regeneration region 18 shown in FIG. 1, the rolling gravel layer 21 offset with the drainage pipes 22 is divided into a pump region 26 and a cistern region 27, concrete edge stones being provided as the separation 25. The area ratio of the pump region 26 to the cistern region 27 is 2:1 in the present case. Of course, a pond operation is also possible without subdivision or with other ratios, but an area ratio of 2:1 has proven particularly advantageous for a smooth swimming operation.In the pump region 26, the drainage pipe 22 is combined with the pump shaft 11 and the collected purified water is exclusively returned to the primary pond 1. The cistern region 27 has a separate drainage pipe 22 which is connected via a flange 28 to the pipe connection 29 lying outside the regeneration pond 2, the pipe connection 29 leading into the vertically arranged standpipe 30 in the cistern 6. The standpipe 30 is closed at its underside pointing toward the bottom of the cistern 6 and ends at its upper side at the level of the normal level of the regeneration pond 2 with an outlet opening 31, through which excess water thus flows from the regeneration pond 2 into the cistern 6. In practice, for the cisterns 6, which can have any desired volume, a sufficient size is chosen which corresponds to the expected average amount of rain in order, if appropriate, to be able to supply other regions with water in addition to the swimming pool system. An emergency overflow 38 is preferably provided below the level of the outlet opening 31 in the cistern 6, as a result of which it is prevented that water is forced back from the cistern 6 into the swimming pool system when the cistern 6 is overfilled. At the bottom of the cistern 6 there is arranged a low-voltage pump 8 which is controlled by the sensor 9 in the pump shaft 11 via the control line 7, the low-voltage pump 8 being connected to a pipeline 32 which ends above the ground and via which water is pumped from the cistern 6 into the regeneration pond 2 if required in order to compensate for the level of the swimming pool system.It is provided that the entire swimming pool system ideally is to feed only rainwater, for which purpose rainwater is preferably fed via a rainwater line 33 into the regenerating pool 2, from where the excess water runs via the pipeline 29 into the cistern 6. It is of course also possible to supply rainwater to the swimming pool 1 and / or the cisterns 6 instead or additionally. The advantage of feeding into the regeneration pond 2, however, is that the rainwater first passes through a cleaning step before it is stored in the cistern 6.FIG. 2 shows the swimming pool system from FIG. 1 with minor, non-relevant deviations in the top view. In the detailed description of FIG. 2, reference is first made to the rainwater line 33, which is difficult to see in FIG. 1. In the embodiment shown here, the rainwater line 33 ends with its last section above the planted zone 37 which surrounds the entire regeneration pond 2.In the following, the details will furthermore be described in particular, which cannot be seen or cannot be clearly seen in the sectional illustration of FIG. 1. Here too, several levels have been picked up again, which are reproduced in a drawing. In the interaction of FIGS. 1 and 2, the person skilled in the art can, however, easily classify the spatial arrangement of the plant parts which would normally be arranged in different planes in the respective representations.Thus, in the plan view of the swimming pool system, it can be seen that in the embodiment shown the conduit 5 for returning the water after passing the bypass 12 is divided so that two outflow openings 39 are available, which are each arranged in the corner regions of the side of the swimming pool 1 opposite the overflow 3 at a sufficient height for producing a source 34 of waves above the pool surface. In this way, it is ensured that all contaminants floating on the pond surface are captured by the wave movement and conveyed in the direction of the overflow 3, where the excess water is guided into the lower-lying regeneration pond 2 and the coarse contaminants are captured in the filter basket 4. The line 5 itself is located in the earth and, starting from the pump shaft 11 arranged laterally in the regeneration pond 2, is guided past the pond system to the side of the swimming pond 1 opposite the overflow 3, where it is divided after passing the bypass 12. The two parts are introduced horizontally underground in the corner regions into the pool 1, the end pieces of the line 5 merging into the vertical shortly after entering the pool 1 and ending above the pool surface with the outflow opening 39.The bypass 12, which comprises a shaft 13, a shut-off cock 14 and an arrangement 15 for water flushing, is not in use during normal swimming operation, but is used only for flushing the system after a relatively long standstill. For this purpose, the shut-off cock 14 is closed and the arrangement 15 for water flushing is activated, wherein the contaminated water is discharged into the shaft 13 and seeps in the ground.The overflow 3 is arranged in each case in the side center between two adjacent sides of the swimming pool 1 and of the regeneration pool 2, wherein the filter basket 4 combined with the overflow 3 covers the planted zone 37 of the regeneration pool 2 at this point.The frog of the swimming pool system is the regeneration pool 2 with the pump shaft 11 let into it as far as into the rolling gravel layer 21 of the regeneration area 18 together with the low-voltage pump 10 and the sensing element 9, wherein the pump shaft 11 in the present case is arranged laterally in the regeneration pool 2 directly next to the planted zone 37. In the plan view, the division of the regeneration region 18 into two by the separation 25 from concrete curbstones and the serpentine covering of the rolling gravel layer 21 with drainage pipes 22 are illustrated, wherein in the present case a division of the regeneration region 18 in a ratio of 2:1 into a pump region 26 and a cistern region 27 can be seen. In this case, the larger area of the pump region 26 is flushed through by the circulation for twenty four hours a day, while the smaller area of the cistern region 27 is flushed through only temporarily when the rainwater inflow is occurring, so that the less used sand layer 19 of the cistern region 27 is more continuous, so that the risk of blockages and overfillings of the pond system resulting therefrom can be avoided or reduced if appropriate by the division into two when the rainwater inflow is strong, wherein the area ratio of 2:1 has proven to be particularly advantageous. The coils of the drainage pipe 22 in the pump region 26 are in flow connection with the pump shaft 11 and thereby form a circuit into which the pump shaft 11 is integrated. In this connection, they supply the regenerated water for recirculation, while the drainage pipe 22 in the cistern region 27 which is closed off at its end by a closure cap 40 is in flow connection via the flange 28 with the pipe connection 29 to the cistern 6 and supplies exclusively regenerated water for the water supply in the cistern 6.In addition, in the plan view of the cisterns 6, it is possible to see the standpipe 30, which is designed as an overflow for the pipe connection 29 and has the outlet opening 31, the low-voltage pump 8, which is operatively connected to the measuring sensor 9 via the control line 7 and is simultaneously in flow connection with the above-ground pipe 32 for the purpose of replenishing the regeneration pond 2, and the emergency overflow 38.LIST OF REFERENCE CHARACTERS1 Swimming pool / primary pool 2 Regeneration pool / secondary pool 3 Overflow 4 Filter basket 5 Line for recirculating the purified water 6 Cistern 7 Control line 8 Low-voltage pump 9 Measuring sensor 10 Low-voltage pump (circulation pump) 11 Pump shaft 12 Bypass 13 Shaft 14 Shut-off cock 15 Arrangement for water recirculation 16 Seal 17 Surface pool region 18 Regeneration region 19 Sand layer 20 Stainless steel screen 21 Rolling gravel layer 22 Drainage pipe 23 Starting point (pump shaft) 24 End point (pump shaft) 25 Separation 26 Pump region 27 Cistern region 28 Flange 29 Pipe connection 30 Stand pipe 31 Outlet opening 32 Pipe 33 Rainwater pipe 34 Source 35 Foundation 36 Base plates 37 Planted zone 38 Emergency overflow 39 Outlet opening 40 Closure cap
