Definitions

  • the present invention relates to a recreational device that allows people to cool and play under continuous water sprays.
  • Beaches may be closed due to water conditions, a lack ot surf patrols, or the presence of animals including sharks or jellyfish.
  • Other waterways like rivers, dams and lakes may be closed due to flood conditions, debris or fast flowing water.
  • additional beaches and waterways may be closed due to sporting events or the like.
  • Some beaches provide outdoor showers but they are not effective at cooling and cannot be used for play.
  • Some recreational areas provide water park areas built into the infrastructure, but these devices suffer from a number of drawbacks including cost to build and the need for water recycling which requires chemical dosing, UV and other treatment.
  • a portable play device for spraying water from an open water source onto user(s) comprising:
  • the self-contained device of the present invention enables people, particularly children, to enjoy the cooling effect of water via the spray(s) by way of an inexpensive portable system that uses water direct from a water source without the need for expensive infrastructure or chemical dosing, UV and other treatments.
  • the device can take advantage of local open water sources, such as natural water sources including seawater, harbours, dams, lakes, or rivers; or man-made open water sources like swimming pools and the like.
  • the device of the present invention does not require the use of either recycled water or expensive potable (mains supply) water.
  • the device of the present invention is able to utilise available local water sources, and does not require a purpose built water supply, for example mains water or a closed loop water source used in fixed water devices. As such, the device of the present invention is able to utilise any available existing water source without needing water supply infrastructure.
  • a portable play device for spraying water trom a water source onto user(s) comprising:
  • one or more spray(s) to spray the water from the device onto the user(s); and a stabilisation mechanism that stabilises the device in use, but allows the device to be moved when not in use.
  • a portable play device for spraying water trom a water source onto user(s) comprising:
  • a pump to pump water from the water source via the suction hose;
  • one or more spray(s) for spraying water including: high-level fan spray(s) to deliver medium to large droplet spray s in arcs a distance from the unit; and/ or low-level misting spay(s) to deliver fine misting, tor example around the base of the unit, to allow user(s) to play close to the unit.
  • a method of providing a water based play area on land suitable for children and/or adults comprising:
  • the present invention provides a versatile play device. Although the device can project a spray over a wide area and thus provide a good size play zone, it is portable allowing it to be easily relocated depending on need. For example, the device could be moved into position each morning and taken away to be stored at night. Its portable nature avoids the high infrastructure costs of an in-build system. In addition, because it can make use of a local water supply, it does not require expensive and complex water treatment systems needed for recycled water.
  • the portable spray device of the present invention enables 'pop up' water parks to be created when and where the need arises.
  • the use of a stabilisation mechanism helps ensure the device is robust and safe to use in a busy public environment since it receives additional stabilisation from being moved or falling over.
  • the device is contemplated for use in a wide range of locations. It is particularly suited to a beach where it can make use of seawater but it can be equally used in any location where there is access to open water, for example a harbour, dam, lake or river. As well as using natural water sources, the device can be used beside a pool or other man-made water feature.
  • the spray radius can be tailored to ensure that the water flows back into the pool.
  • the device can be connected to a potable (mains) water source if desired.
  • the device may comprise a water suction member to extract water from the water source.
  • Suitable water suction members include hoses or pipes.
  • the member is a hose.
  • the term hose will be used to describe the water suction member although any equivalent item that performs the same function, for example a pipe or the like, are encompassed by the present invention.
  • the diameter and length of the hose will depend on the volume of water to be sprayed through the device. This will depend on the power of the pump, the distance the device is located from the water source and the vertical difference between the water source and pump.
  • the hose will be capable of sendee at a negative pressure of 5 metres/head.
  • the hose may be made of any suitable material.
  • the hose is a UV stabilised PV C suction hose.
  • the hose may be buried in the sand from the spray device down to the water so as to prevent a trip hazard.
  • the hose can be uncovered and stored with the device.
  • precautions may be taken to prevent the hose from causing a trip hazard or being dislodged from the device or removed from the water.
  • the hose is attached to the device, either as an integral part or more preferably as a detachable item since a detachable hose has the advantage that it can easily be replaced if it becomes damaged.
  • a hose is used with the device, the hose does not need to be supplied with the device and the user can source one themselves. As such, a device without a hose is still encompassed by the present invention since it can be supplied and added separately by a user.
  • a rope (zip-rope) is associated with the suction hose.
  • the rope is preferably a small or medium diameter rope.
  • the rope is attached at one end to the suction filter and at the other end to the device and is laid with the suction hose and buried.
  • the rope is pulled up first, effectively un-zipping and breaking the surface tension of the sand, allowing easy pulling out of the hose and filter.
  • the device of the present invention is designed to be used in a variety of environments, including those where the water contains particulate matter.
  • the device may be used on a beach where sand will be mixed with the water being drawn into the device.
  • the inlet ot the suction hose comprises a sand filter. This prevents or reduces sand particles entering the device and potentially clogging the pump, sprays or other areas.
  • the suction filter is capable of delivering filtered water at a high flow rate. This allows the device to draw a high water flow rate while effectively filtering out sand and other particulate material. Without an effective sand filtration mechanism, the device would become clogged and the ability to draw water would be diminished.
  • the flow rate achievable by the suction filter will depend on the volume of water desired to be sprayed from the device. In a preferred embodiment, the sand filtration device has a minimum flow rate of 1.8 litres/ second.
  • a suction filter is a sand spear, which is designed to achieve a strong flow rate whilst effectively filtering out sand.
  • the sand spear is a stainless steel Y w ire or PV C sand spear.
  • the sand spear in use would be buried in the sand below the water line to allow it to draw water but not present a trip hazard.
  • the sand filter openings will be approximately 0.15mm to filter out most sand and fines. Finer particles that do get through the filter should be small enough to travel through the device and exit through the sprays (whose apertures may be designed to be larger than the sand spear filter mesh).
  • a different inlet filter can be used.
  • Such a clear water inlet filter may still contain a coarse filter to prevent larger particulates from entering the device but it does not require the fine mesh needed to filter sand. Providing a coarse inlet filter will also prevent a user inadvertently getting a finger or hand stuck in the suction hose.
  • the inlet point of the suction hose contains a coarse or fine filter
  • one or more additional filters are also provided to further filter out unwanted particulate material.
  • the device is designed to work in an environment where some fines contamination is inevitable, providing further filters may reduce the amount of fines entering the device, which will further reduce the risk that a part of the device becomes blocked.
  • further filters within the device will add a further element mat may need to be unclogged or replaced, and may also increase the water pressure needed to pump the water. As such, the number and mesh size of the filters will depend on the intended usage of the device.
  • the device may further comprise a backwash system to enable the flow to be reversed to clear the inlet filters of blockage.
  • the device uses a pump to draw in water and force it through the spray(s).
  • the pump is an impeller pump, preferably a marine grade impeller pump, which is capable of pumping seawater and abrasive fines (e.g. sand).
  • the pump has a self- priming suction lift of at least 5 metres.
  • the device preferably contains one pump, further pump(s) may be used if desired.
  • the pump should be capable for changing direction (reversing the flow) to provide a positive "back-wash" to clear blockages of the filter/ s.
  • the pump must be sufficiently powerful to draw water, potentially through a sand spear, and create sufficient water pressure to create a usable spray pattern, possibly through a number of spray nozzles.
  • the power requirements must take into account the location of tie device versus the water source. For example, on a beach, the device may be placed at the top of the beach, and thereby potentially 10-15 metres away from tie water and vertically displaced by 5 metres or more. In tiis circumstance, tie pump must be sufficiently powerful to draw water over this distance into and through the device.
  • V arious power sources are contemplated for use with tie present invention to drive tie pump.
  • tie power source is capable of powering the pump for continuous operation (e.g. 12 hours or more). This allows the device to be switched on at tie start of a day and then left alone tor continuous use during tie day.
  • tie pump is fixed to an electric motor.
  • tie pump may be directly fitted to a small petrol or diesel engine.
  • tie electricity can be obtained from any suitable source.
  • the power source is an internal power source.
  • the power source is an external power source, e.g. mains electricity.
  • the device incorporates a self-contained electric generator.
  • the generator is preferably capable of continuous operation (e.g. a minimum of 12 hours) and therefore preferably has a fuel capacity of 12 hours or more.
  • the generator will comply with Australian and international emission standards.
  • the exhaust of the generator may be modified to discharge exhaust gas at high level to facilitate dispersal of the exhaust gases.
  • the device housing may be modified to provide vents to further facilitate dispersal.

  • the device may also contain vents close to the generator to allow a suitable in-flow of air.
  • vents are provided in the base of the unit.
  • Mechanical (fan) ventilation can be incorporated to assist in ventilation when a generator is installed.
  • the mechanical ventilation can incorporate the generator exhaust in a dilution flue and discharge at low level under the unit.
  • the generator will primarily provide power for the pump, it may also provide power for any controls that are present in the device, for example Wi-Fi or Bluetooth connectivity, computer control of the spray patterns and/ or ventilation fans.
  • the device may be powered from a mains electricity source. This is possible where such a source is located near to the device.
  • the device may be powered from solar rechargeable batteries.
  • the device may be configured to allow a generator to be contained within the housing.
  • the device may be sold including a generator.
  • the device is supplied without a generator with the user providing their own generator or mains electricity power supply.
  • the device is configured to grant a user access to the internal mechanics of the device. This allows access and placement of a generator as well as access to adjust or fix other components.
  • the device may contain a (lockable) access hatch to enable access.
  • the device has an internal lifting mechanism that elevates the outer skin of the unit to gain access to the pumps, generator and other mechanics.
  • the lifting device may not need a door or access panel to access the inside.
  • the device is designed to have a low centre of gravity and to be shaped to provide the maximum stability to the device while in use. This helps ensure the device cannot tip over during use.
  • the device may further include a stabilisation mechanism.
  • the purpose of the mechanism is to ensure the device remains stable during use but allows the device to be moved when not in use. During use, it is possible that a number of children and/or adults will be running and playing around the device. As such, the device must be stable enough to withstand people falling into or being pushed against the device without it falling over.
  • the stabilisation mechanism therefore reduces the likelihood that the device can tip over and/or move during use. At the same time, the stabilisation mechanism should be light enough when not in use to allow the device to be portable.
  • the stabilisation mechanism incorporates a ballast tank.
  • the ballast tank When filled with water, the ballast tank provides a low centre of gravity, which provides stability to withstand knocks or pushes. However, when not in use, the water can drain out of the tank reducing its weight such that the device can be lifted.
  • the use of a ballast tank has the advantage that the device is self-stabilising, using the water source itself to provide stability .
  • the ballast tank additionally has the advantage that it provides a lower velocity water area within the device to allow sand or fines that travelled through the inlet filters to settle at the bottom of tie tank.
  • the ballast tank provides the multi-function of a settlement tank, back-wash water and stabilisation mechanism.
  • the ballast tank includes a drain valve that enables the tank to empty at the end of the use cycle, removing the settled sand and other fines if needed.
  • the ballast tank may also provide a water source for back-washing the inlet filters.
  • the location of the ballast tank in the device may be arranged to ensure the weight is evenly distributed within the device to maximize the stabilisation ability and minimize the risk that the device may topple in one direction.
  • the device may contain one or more sand-screws to provide stabilisation.
  • the sand screws may be preferably located within the device and screwed into the sand from inside the unit.
  • the device may contain any suitable means to provide stabilisation. This may include anchor points that facilitate connection to pre-set anchors in the location, stabilisation points that allow a user to place a spike or other device into the ground holding the device in place, or any other means to help ensure it remains stable in use, including weights such as sand bags positioned inside the device.
  • the stabilisation means will be designed such that when in use, the device is stabilised but that the stabilisation means can be undone when not in use allowing the device to be moved. As such, even with a stabilisation mechanism, the device of the present invention differs from permanent water features that must remain in-situ.
  • the device may contain heavy solar chargeable batteries that assist in the stabilisation of the device.

  • the ballast tank also has a drain 7a that allows water and any accumulated fines to be discharged from the device at the end of its usage period.
  • the rate of flow of the water is controlled via the optional flow control valve 13 that enables the user to adjust the flow rates of the device to achieve the desired level of water spray.
  • FIG. 5a and 5b Alternative devices are shown in Figures 5, 5a and 5b. Many of the elements are the same as with the previous example but in this instance the device is controlled via a remote controller 14. This may be controlled via Wi-Fi, Bluetooth or any other suitable remote control system.
  • the device also has an additional filter 15 before the misting sprays. This is used because the aperture of the misting sprays is much narrower than the tull flow sprays and therefore the misting sprays are more likely to become clogged. Using an additional fine filter will help to remove this potential issue.
  • FIG. 6 An example of a sand spear 1 is shown in Figure 6.
  • the sand spear is a stainless steel Y w ire or PVC tubular filter that filters out sand and fines to less than 1mm in size.
  • the V wire design allows the filter to be semi self-cleaning. Where the suction inlet is not likely to be clogged by sand (for example in a lake, pool or river environment), a sand spear is not necessary.
  • Figure 7 shows an alternative inlet filter that can be used in these situations.
  • the mesh 16 is wider than with a sand spear.
  • a coarse filter is used to prevent large debris like twigs or leaves from entering the suction hose as well as preventing users from putting their hands into the suction hose and getting them stuck.
  • FIG 8a shows an example of the inlet filter of figure 7 in water.
  • Figure 8b shows a float 17 attached to the inlet filter 16 to ensure that the inlet does not sink to the bottom. This will help avoid sucking up debris and other sediment by ensuring the inlet remains in clear water.
  • the ballast tank is shown in figure 9.
  • the ballast tank 7 provides a low centre of gravity that helps to stabilise the unit. The tank also reduces the velocity of the water flow, allowing settlement of sand and 'fines' out of the water supply. It can be seen that the tank contains an inlet 7b from the pump and an outlet 7c to the sprays. These are located at the top of the tank.
  • the ballast tank contains a downward drain valve 7a and the tank can be emptied at the end of a cycle.
  • the weight difference between the ballast tank when empty versus when full has a significant impact on the overall weight of the device thereby helping ensure the device is stable when in use but light enough to carry when not.
  • Figure 10a shows an example of the manifold and spray system.
  • the manifold 8 is made up of a number of fittings and pipes to deliver water under pressure from the pump or via the optional ballast tank to the various spray heads on the unit.
  • the manifold in Figure 10a is shown connected to high volume fan sprays 9.
  • the manifold in Figure 10b is shown connected to both low level misting sprays 10 and high volume fan sprays 9.
  • the optional flow control valve 13 is shown between the lower misting sprays and the upper fan spray manifold.
  • Figure 10c shows the optional flexible hose connection to the manifold
  • Figure 11 shows a low level misting spray in more detail.
  • the low height misting spray nozzles provide low volume misting at the lower zone around the unit providing a softer spray for children.
  • the nozzles are capable of passing 2mm sand or silt particles.
  • the misting spray shown is a hollow cone hydraulic atomizer and is an industry standard mister made of brass (or optionally stainless steel). The spray nozzles are installed for easy replacement if they become blocked.
  • FIG 12 shows a high-level high volume fan spray head in more detail.
  • the high-level fan sprays provide a vigorous water spray in fan form reaching approximately 3 metre away from the unit in a continuous circle around the unit. These provide high volume wetting for uses away from the quieter/ softer misting spray.
  • the fan nozzle orifice size is between 5 and 7mm and the j ) sprays are industrial high quality UV protected polyurethane. As with the misting spray, the fan nozzles are designed to be easily replaced.
  • the generator 5 is shown with a connector to the controller 14 to control the generator and pump from the outside of the housing. Controller 14 may optionally be remote enabled via Wi-Fi, Bluetooth or the like.
  • An exhaust pipe 8 is shown leading from the generator to allow exhaust fumes to escape from the top of the device.
  • ventilation grills/ openings 1 are provided.
  • the delivery pipe and manifold 8 leads from the ballast tank to provide high-pressure water to both the misting sprays 10 and fan sprays 9.
  • Optional in-built wheels 20 may be provided with the device to allow it to be moved easily into position.
  • Figure 13 includes the same features as Figure 1 and the same numbering has been used.
  • Figure 13 also includes a secondary filter and backwash system 6. Where very fine sand exists, a secondary filter 21 may be installed. This can be an auto backwash filter to remove the accumulated fines via the backwash controller 22.
  • FIG. 14 is a spray unit without ballast tank or secondary filter and backwash.
  • Figure 15 is a spray unit with no generator and a mains electrical connection point.
  • Figure 16 is a spray unit containing sand screws 23 instead of a ballast tank to provide stabilisation.
  • the sand screws are screwed into the sand from inside the unit.
  • Two sand screws are depicted in the figure but more or less could be used depending on need.
  • Figure 17 is a spray unit with ventilation fan 24 and raised base to provide all ventilation from under the unit 25.
  • Figure 18 is a spray unit with internal telescopic lifting device to raise the outer shell to provide access to internal elements of the device.
  • the present invention contemplates any lifting mechanism that enables lifting the outer shell of the device.
  • Once such lifting mechanism is comprised of two fabricated square section aluminium sections (27 and 28).
  • the internal section 27 slides within the outer section 28.
  • the outer section is fixed to the base of the unit 29, the inner section fixed at the top to the outer shell of the spraying device.
  • a roped pulley device 30 is fitted to the inner and outer sections of the lifting device. The end ot the rope passes through the base of the whole spray device. When this rope is pulled the inner section is lifted vertically within the outer section, here by raising the outer shell of the spray unit to allow access to the pump and internal working of the spray device.
  • the internal section 27 which engages with the outer shell to lift it vertically can be removed to gain full access to the internal mechanics of the device.
  • a spiral hose 31 connecting the pump to the delivery manifold or sprays is advantageously used to allow vertical movement without disconnection of the pump.
  • the spiral hose 31 can be seen in Figure 18.
  • Figure 19 is the internal telescopic lifting device at a 2 to 1 lifting ratio.
  • Figure 20 is the internal telescopic lifting device at a 4 to 1 lifting ratio.
  • the portable spray device of the present invention does not initially contain any water and is therefore relatively light allowing it to be moved.
  • the device can be placed in a suitable position near to a water source.
  • the device may contain wheels and/or handles to enable it to be manoeuvred.
  • the suction hose and inlet filter would be extended into the water supply.
  • the sand filter and hose may be buried in the sand layer.
  • a Zip Rope is preferred to be laid with the hose to allow easy removal of the hose.
  • the sand filter will be buried below- the water level
  • the Zip Rope is fixed to the end of the sand filter to allow- easy removal of the filter by breaking (un-zipping) the sand from above the hose and filter.
  • the sand filter, hose and zip rope can be buried to reduce trip hazards.
  • the primary filter can be lowered directly into the water supply.
  • a float may be attached to the filter to raise it above the bottom of the water source to reduce blockages and keep the filter in clear water.
  • the device can be opened via the access door or internal lifting device to start the generator.
  • the generated power can operate any optional ventilation f an(s) and provide power for the pump electric motor.
  • the generator may have an external shut off device and may also have tilt shutoff in the event that, despite stabilisation, the device is tilted or pushed over. If the device uses sand screws that are accessible from the inside of the device, they can be screwed into place at this stage.
  • the pump may be started via an external on/ off switch controlling the electrical power from the generator (or main power as appropriate).
  • the start can be delayed to allow the operator to move away from the unit.
  • a Wi-Fi or Bluetooth connection via, for example, a smart phone can turn the pump on and off.
  • the water With a self -priming pump, the water will flow to the device. If a ballast tank is used, the water will flow into the ballast tank to fill the tank. The full tank provides additional stability to the unit.
  • An optional secondary filter may be installed prior to the pump and (optional) ballast tank if required to remove silt and mud, depending on water quality. The location of the filters may be optimized depending on the device configuration and quality of water.
  • the water will then travel up the supply manifold and discharge from the external sprays and misting nozzles.
  • the device will then continuously spray water from the water source until the device is switched off.
  • the pump is stopped and the generator switched off. If a ballast tank is used, it is allowed to drain.
  • the end of the zip rope is then located and pulled up thereby 'unzipping the sand along the length of the hose and making it easier to remove the hose since the sand has been de-compacted.
  • the hose and inlet filter are then collected. The device can then be moved for storage or other purposes.
