Description

The redundant array control system of water slide

Background of invention

FIELD OF THE INVENTION

The present invention relates generally to water channel, particularly relate to and a kind ofly upload redundant array pumping system and the related diagnostic system that reaches such water channel of controlling that graduating can be given the water channel of water skier and/or coaster at a low friction slideway or other slideway surface at one or more high-velocity flows are joined together.

Background of related

In the past twenty years, the growth phenomenon of family's amusement on water facility is proved, such as the boat paradise and the aquatics programme in traditional public place of entertainment of family.Typical main water channel project comprises drifts about on water skiing, the river and water channel fortune wood.These water channels allow water skiers above one eminence or starting point along the inclined-plane or skewed slot slide to a lower (both can I also can be) by coaster, such as a puddle.The water skier's that gravity or gravity cause momentum is the main drive that the participant is slided downwards by traditional water channel.

For example, the U. S. Patent 4,198,043 of Timbes has disclosed a water slide that typical gravity causes, and it is characterized in that a water skier slides into lower place, pond from top initial pond by gravity.In the same manner, the U. S. Patent 4,196,900 of Becker has disclosed a traditional descending water slide that has circulating water.In each example, all water mainly is used as a kind of oiling agent of water skier and waterdrop slidable surface and/or the entertaining and the enjoyment of increase water skiing, such as the spray that splashes.

A more close phenomenon is the water slide that is called " injection water curtain ".These water slides typically use one or more high pressure injection way, inject current at a high speed on water slide surface, advance the participant in current, or in face of current, or the speedup with gravity therein.The speed of the position of nozzle, specification and injection current and flow have indicated the form of final current and water skier's path and speed.Injecting the water curtain technology makes a variety of water slides and specification thereof become possibility.

For example, Master Blaster just sells this injection water curtain water slide, and it also can obtain from Texan New Braunfels NBGS.Sometimes the water slide of Master Blaster is also with reference to the water slide of " water channel roller-coaster " type, because it provides the current that are equivalent to the roller-coaster slideway in essence.Especially, it has the ascents and descents that is similar to traditional roller-coaster, also can make the sliding at least last inclined-plane of water skier.

In the water slide of typical water channel roller-coaster type, hydraulic spray partly arranges along the upward slope of level and/or water channel, so that high-velocity flow to be provided, the water skier is offset or to increase the water skier's who is caused by gravity power.Such high-velocity flow can increase water skier's speed at level or descending, make its greater than only by gravity itself the speed that can produce.High-velocity flow also can be used to reduce and/or limit the speed of water skier on the slideway surface, and is too high or fly out at the inappropriate place of slideway with the speed of avoiding the water skier.Can be with reference to U. S. Patent 5,213,547.

The water slide of the injection water curtain class that another kind is popular is the curtain flowing water slideway of simulation ripples.For example, Flow Rider just sells this simulation ripples water slide, and it is from adding the Wave Loch of livre Buddhist nun Asia, and Inc of La Jolla also can obtain.The simulation ripples water slide of Flow Rider comprises a liner slideway surface with engraving of desirable ripples simulation shape, can produce one or more high velocity jet water curtains, the water curtain stream that injects makes progress along the slope, has therefore formed the approximation surface of desirable surfing ripples.The thickness and the speed of such water curtain stream have formed the effect of skidding or sliding simultaneously between slideway surface and water skier and/or coaster, and have formed the effect that drags on water skier of skidding on the water curtain stream and/or waterwheel.Traction that makes progress by balance and downward gravity, skilled water skier can drive water curtain stream, and surfing ripples experience simulation and/or that strengthen is made and obtained to the left-falling stroke hydrodynamic(al) that can be similar to surfing thereon.Can be referring to U. S. Patent 5,401,117.

Inject the description of water curtain stream in above each, current are to be injected by the high pressure pump system that is connected to the one or more water jets that are positioned at diverse location place, water channel surface.High pressure pump system produces necessary preceding point or transmits quantity and the needed hydraulic pressure of speed that forms required current from each water jet as main driving mechanism.Traditionally, pumping system has comprised one group of pump, and each pump provides the water source to a nozzle that is positioned at slideway surface special position.Series of nozzles interconnects, and each pump has a suitable manifold to provide essential water source to each nozzle.The specific standard and the quantity that are the pump of given system's selection are decided by following factors, such as: the kind of the size of the cost of each pump and capacity, specific slideway and proterties and required slideway effect.Typically, the suction side of each pump is connected in water filter, and filter is connected to pond or water container again.

By accident, can find also that a pump in the water slide pumping system breaks down or impaired, and capacity and/or the preceding point that needs can not be provided again.In this case, this pump will be closed, and change or repair.Similarly, relevant filter or nozzle can be because crowded or stop up and can not meet the requirements of flow, and in this case, whole water slide all can be adversely affected, and need close the maintenance of keeping in repair and/or carrying out failed element.

This is a disadvantageous and undesirable situation, because client can become uneasy or lose the confidence when the wait slideway keeps in repair and starts.Can become in a dilemma the client on the slideway of closing by force in the maintenance of carrying out element and/or when changing.Can cause the decline of water skier's quantity and the reduction of slideway owner profit excessive fault time.To certain water slide,, also have potential safety hazard if one or more nozzle lost hydraulic pressure suddenly because water pump lost efficacy.For example, in the slideway of water channel roller-coaster type,, cause stopping and falling back of water skier possibly, bump against with the water skier who just enters the part of going up a slope in the unexpected forfeiture of the nozzle hydraulic pressure of the part of going up a slope with ascents and descents part.

If such drawback can be overcome or alleviate, will be great advance and existing great commercial value.

The specific descriptions of most preferred embodiment

For the purpose that illustrates and understand easily, we mainly discuss the present invention according to the water slide of water channel roller-coaster formula, as shown in fig. 1.Yet, should be realized that some or all features of the present invention described here also can be used to control the slideway with a plurality of spray nozzles of other type effectively, for example simulate ripples water slide and tank slideway or the like.

Fig. 1 is the rough schematic view of water slide 90 with water channel roller-coaster formula of feature of the present invention.Water channel roller-coaster 90 originates in traditional pond 32 of setting out, and it allows water skier 29 to enter slideway.Slideway comprises a slideway surface 70 that forms passage.Slideway surface 70 can be made by the suitable material of some, for example injects resin, concrete, the cement slurry of glass fibre, wood, vinyl resin, polypropylene and the metal etc. of sealing, can the segmentation manufacturing, and an end connects an end ground waterproof sealing.Slideway surface 70 is supported as wood, metal, glass fibre, cable, soil and concrete etc. 71 by suitable support structure.

Although slideway surface 70 is continuous, but for convenience, first flat part 70a ' that still can be divided into it falling ramp that is connected in initial pond 72, first falling ramp part 70b ', first bottom 70c ' of falling ramp, from first rising part 70d ' that decline bottom surface 70c ' makes progress, first top 70e ' of rising part 70d '.After this, second flat part 70a of falling ramp continued to enter in slideway surface 70 ", second falling ramp part 70b ", second of falling ramp bottom 70c "; from decline bottom surface 70c " second rising part 70d making progress ", rising part 70d " second top 70e ".After this, the 3rd flat part 70a of falling ramp continued to enter in slideway surface 70 " '; the 3rd falling ramp part 70b " ', the 3rd of falling ramp bottom 70c " '; from decline bottom surface 70c " ' the 3rd rising part 70d making progress " the 3rd the top 70e of ', rising part 70d " ' " '.After this, the 4th flat part 70a of falling ramp continued to enter in slideway surface 70 " ", the 4th falling ramp part 70b " ", the 4th bottom 70c of falling ramp " ", from decline bottom surface 70c " " the 4th rising part 70d making progress " ", rising part 70d " " the 4th top 70e " ", it is connected in the end basin 73 of facing the position with first top 70a ' of initial pond 72 and falling ramp mutually.

Upwards quicken module 42 and be positioned at the rising part 70d ' on slideway surface 72, horizontal accelerator 40A is positioned at second sloping portion bottom surface 70C on slideway surface 70 ".Decline accelerator 44 is positioned at the 3rd the sloping portion 70B on slideway surface 70 " ', second horizontal accelerator 40B is positioned at the top 70A of the 4th sloping portion on slideway surface 70 " ".Each quickens module and is used for spraying into the tentiform current to slideway surface 70, to promote the water skier or the sea scooter of there.The current that overflow, plain boiled water (being exactly the spray that spills) and the instantaneous water wave that evokes of water skier can be discharged by outside, waterdrop slidable surface edge or along the through hole of slideway bottom surface and/or side.Can be referring to the U. S. Patent 5,213,547 here.Leading to the water that respectively quickens module 40,42,44 and initial pond 72 can be provided by the high-pressure water that the back will be described in detail.

With reference to Fig. 2 a (plan view) and Fig. 2 b (side view).Describe one and comprised high-pressure water flow/high-pressure water 22, water flow control valve door 23, with the propelling module 21 of the current forming nozzle 24 that has adjustable hole 28, all said modules co-operation have formed the discrete injection water 30 of pre-motion orientation as shown by arrows.The hole 28 of current forming nozzle 24 preferably has the rectangle of an elongation, as shown in the figure, so that eject the tentiform water jet.The length of hole takes advantage of the wide size can be respectively from 200 centimetres of 20 centimetres to 40 centimetres * of 1/2 centimetre of *.Selectively, other shape and size also can effectively be used.

Advance module further to comprise a slideway surface section 25 very level and smooth, that injection water 30 can flow thereon.Preferably there are enough structural integrities on slideway surface 25, to support the weight of water skier, sea scooter and current.Waterdrop slidable surface 25 preferably has low coefficient of friction, so that injection water 30 and water skier 29 are flowed with the loss of velocity of minimum and moved.Module 21 can be with the following made of some: inject resin, concrete, cement slurry, sealing wood, vinyl resin, polypropylene and the metal etc. of glass fibre, and end carries out suitable waterproof and is connected with holding.

Fig. 2 c (side view) has described the water skier (pre-motion orientation as shown by arrows) who slides on module 21a, a 21b in a series of connections, the 21c.Link 26a, 26b between module 21a, 21b, the 21c and 26c allow to reach desirable angle on whole length of the promotion module that is connected, as on operating, on the space and economically.Link 26 can be connected by bolt, glue bonding or module 21 be with form continuous casting end to end.During connection, the slideway of each module surface 25 and its connection module be linear alignment strictly, and water skier 29 who slides in the above and the injection water 30 that flows are in the above slipped over safely respectively smooth-goingly.When a module had the nozzle 24 that occurs from a position of the length direction of (shown in Fig. 1 c) along slideway surface 25, preferably the no nozzle end on slideway surface 25 expanded to and is stacked and placed on the top that connects nozzle 24 at link 26 places.Further, the preferably bottom of nozzle 24 expansion and as slideway surface 25.

Each advances the length of module 21 to change according to required operating feature, structure technology or transportation parameter.The width of module 21 can be too narrow to and allow a water skier to be sitting in or crouch on slideway, and leg and water (flow) direction are straight slides, and about 50 centimetres (20 inches), or wide to allowing a plurality of water skiers to be sitting on the sea scooter abreast or slip simultaneously in the water skiing pipe.

Each nozzle 24 is made and be placed in suitable position, make it on the direction parallel, spray injection waters 30 by adjustable hole 28 with the length direction strictness on slideway surface 25.For slip and the current that make the water skier keep continuity, when module was linked to be given facility (shown in Fig. 2 c) serially, all nozzles preferably were transferred to identical direction, with the transmission of increase kinetic energy and moving of water skier.The state of injection water 30 (be exactly temperature, turbidity, pH-value, chlorine is residual and salt etc.) is normal tour swimming pool, lake or the seawater that is suitable for people's swimming.

Fig. 3 a, 3b example along a part of waterdrop slidable surface 25 from the lower to higher position promote water skier 29 upwards accelerator 42 and operation.Water skier 29 quickens module 21 and moves upward along its length shown in Fig. 3 b entering near an end of nozzle 24.Quicken on the module (Fig. 3 b) at each, nozzle 24 is injected into injection water 30 on the slideway surface from water source 22 by adjustable aperture 28, preferably between water skier and slideway surface.The adjustment that water flow control valve door 23 and adjustable aperture 28 allows speed, thickness, width and the pressure to current to carry out.The thickness of tentiform current and speed preferably are adjusted into it and produce the effect that drags or spur on water skier and/or water skiing vehicles, produce the effect of skidding or sliding between waterdrop slidable surface and water skier and/or sea scooter.The effect of skidding reduces or has reduced the frictional force between water skier/water skiing vehicle and the slideway surface, and simultaneously, the effect that drags or spur has produced the pulling of water skier/water skiing vehicle along slideway surface 25.

In quickening the situation of module 21, the speed that injection water 30 moves is than the water skier's 29 who has just entered speed height, and therefore, the transmission of movement from high-velocity flow to the low speed water skier quickens the water skier and near the speed of the current of rapid movement.In the process of this transmission of movement, can form little instantaneous water wave 33 in water skier's back.Allow the water wave outflow slideway surface 25 of excessive growth can reduce instantaneous water wave.As an alternative, other following water hole of through hole mechanism or permeable through hole also can be used as same purpose.

Upwards accelerator 42 can comprise an independent accelerator modular unit 21 (Fig. 3 b) or some module 21a as required, (Fig. 3 a) for 21b, 21c etc.In the embodiment of the polylith module shown in Fig. 3 a, the acceleration of corresponding growth along with the progression increase of the water speed that sprays from each continuous nozzle 24a, 24b, 24c etc., water skier 29 can move on to module 21b, module 21c etc. from module 21a, up to reaching desired big flood speed.The hydraulic pressure of each nozzle bore 24a, 24b, 24c can be regulated the operating characteristics that provides required like this.

At the typical water curtain style water slide that injects, the scope of nozzle pressure can be according to following factor from about 5 pounds/inch to 250 pounds/inch: the size and the specification of (1) nozzle opening; (2) water skier is with respect to the weight and the frictional force on slideway surface; (3) continuity of slideway skin friction; (4) speed of water skier's ingoing stream; (5) water skier is with respect to the physical direction of current; (6) slideway surface tilt or downward angle; (7) increase or the minimizing of desired water skier's speed owing to the kinetic energy conversion that flows to the water skier from water.At the injection water curtain style water slide of a use vehicle, then the pressure range of nozzle may be higher, supposes that vehicle can be designed as can bear bigger pressure and can have better effect in kinetic energy conversion than human body.The liquid flow control valve door 23 that quickens module 21 (Fig. 3 b) can be used to adjust nozzle pressure and flow and also can remotely control and programme according to the operating parameter indication.

Advancing 22 places, water source of module 21 to provide the drive unit of required current and pressure or the energy to be one group at each is built in such as the water pump in a suitable pumping station or the building 92 (Fig. 1).These water pumps keep liquid to be connected by pressurized water supply pipe 102,106,100,104 with each accelerator modular unit 40a, 40b, 42,44 respectively.Water pump also keeps liquid to be connected with initial pond 72 and a selectable water wave tank 94.The wet pit that this water wave tank 94 provides a lower also provides a water and/or filtering container for circulating water to collect and to impel the water of outflow to pump again.

In traditional water slide structure, can use a single big water pump to provide current to one group of accelerator modular unit and/or other current injection unit by distribution pipeline.Can also use the less water pump of separation, be used for each and quicken module or a series of module that links together.Be a customized configuration and a quantity, typically limited, such as the capacity of cost and each pump, the type of specific slideway size and character and desirable slideway effect by some factors to the water pump of fixed system selection.In normal operation, the configuration of selected specific water pump does not influence the effect of slideway.

Yet, find that sometimes a pump in the water slide pumping system will lose efficacy or damage, and can not bring into play desired ability again.In this case, water pump will cut out and replace or repair.Similarly, it is not smooth that the filter of associated and nozzle may become, so that desired water velocity does not reach requirement.In this case, opposite influence appears in the water slide that disposes under usual manner, and cuts and generally all require to turn off equipment and/or repair a breakdown parts.

For example, consider the upwards accelerator 42 among Fig. 3 a, become and weaken or no matter former thereby can not operate if supply with the water pump of remote underwater nozzle 24c, be not enough to promote water skier 29 from the current of nozzle 24a, 24b residue ejection and climb up the remaining part in slope because of which kind of.The water skier will stop on the water channel surface in this case.If water channel is not closed, other water skiers are added the ski-running upslope by accelerator 42 upwards, and that is danger close, may knock the water skier who stops and cause injury.

But, turn off water slide and be our that do not expect and disadvantageous situation, fix and restart to make the client of water skiing to be sorry or very impatient because wait for water slide.And, when closing by force, the client on the slideway may by stranded on slideway some times, fixed and restarted up to slideway.Too much pass chance causes reducing water skier's the volume of the flow of passengers, thereby, minimizing slideway owner or manipulator's income.Similar showing, the filter of water slide Hydraulic pump system and the obstruction meeting of nozzle have same injurious effects on safety, quality and the income of water slide.Redundant water pump and filter array

The present invention has partly or entirely overcome above-mentioned restriction, and a kind of water pump system that comprises a redundant water pump and filter array is provided, and after a water pump or associated components inefficacy, helps to recover fast the normal of water slide.Fig. 4 is a rough schematic, has illustrated a kind of embodiment of possible pumping system 10, and it comprises as redundant water pump of inventive point of the present invention and filter array 12.

Pumping system 10 among Fig. 4 is the best argumentation and the understanding of water channel roller-coaster above set forth in fig. 1.As top example and argumentation, water slide 90 generally comprises a reservoir or pond 94 and the pumping system 92 in pumping station.Water supply line 100,102,104 and 106 is connected to the N2 of nozzle separately, N5, N7 and the N10 of accelerator modular unit 42,40a, 44,40b separately from pumping station 92.

Along with the water slide among Fig. 1 90 is brought into use, water skier 29 (using or do not use vehicle) enters beginning pond 72 and begins to glide along downward part 74 in a conventional manner.When entering a part 76 that makes progress, the water skier runs into a upward nozzle N2, and N2 injects the top 76 that one current at a high speed quicken and rising water skier 29 position arrival is gone up a slope.After this, water skier 29 slides to the bottom 78 of descending part, and in the bottom, water skier 29 runs into horizontal nozzles N5, and nozzle N5 injects the top 80 that one current at a high speed quicken and rising water skier 29 position arrival is gone up a slope.Further, slide to the part 82 of a descending downwards, water skier 29 runs into horizontal nozzles N7, and N7 injects one current at a high speed and quickens to make water skier 29 to glide, and gives enough power at last and makes water skier's 29 risings climb over the top 84 of the part of going up a slope.The water skier runs into horizontal nozzles N10 subsequently, and N10 injects one current at a high speed makes water skier 29 quicken finally to climb over the top 86 partly of going up a slope, and also is that water skier 29 arrives slideway terminal point pond or water spraying pools 73.

Pumping system 10 (Fig. 4) more provides an enough big hydraulic pressure to each nozzle N2, N5, N7 and N10, makes water skier 29 finish path described above.In this respect, those person of skill in the art will appreciate that nozzle N2, N5, N7 and N10 both can operate simultaneously, but also continuous running, such as being satisfied continuously a large amount of water skier, or desultory water skier (as required), for example be water skier single or that be separated by.In each case, the following factor that depends on the hydraulic pamp system from the speed of the water of each different nozzle N2, N5, N7 and N10 ejection, size and dimension as nozzle, the hydraulic pressure of nozzle entrance, the route of intrasystem frictional force of Hydraulic pump (or obstruction of current) and nozzle exit free flow.

The hydraulic pressure of each nozzle inlet is preferably kept (Fig. 4) by water pump system.Usually, water pump system 10 comprises a water pump and filter array system 12, and it is arranged to a N+1 redundant array---four main pump/combination of filters 201--204 and a deposit pump/combination of filters 205.Each main pump/combination of filters of array 12 is used under pressure, supplies water by supply line 100,102,104,106 and gives a corresponding accelerator modular unit 42,40a, 40b, 44 (Fig. 1).At least provide deposit pump/combination of filters 205 and fluid coupling in this system, so that any one among main pump/combination of filters 201-204 can be from system separated or bypassed by fluid power and effectively alternative by deposit pump/combination of filters 205.This mode, if a pump/combination of filters runs into not normal or infringement, it can separate from system, and the stand-by storage pump replaces.

Better, water pump miscellaneous in the composition water pump system 10 is arranged by fluid power such as adaptive valve 215, check valve 217, bypass manifolds 219,221 with filter and is connected, so that each pump/filter can " exchange " immediately in conjunction with physical efficiency and one or more deposit pump/filter.In this manner, the pump of an inefficacy or miscellaneous part can be replaced from water pump system when system works or pull down at an easy rate, and do not influence the normal operation of other pump and water channel.Best, this " the instant exchange " realized automatically by an adaptive valve and a diagnostic system as described below.

If desired, the part that an other line filter 225 (" remedying line ") can be used as water pump system 10 provides, and the line filter redundancy of a N+1 is provided.For instance, suppose that a main pump/combination of filters lost efficacy, deposit pump/combination of filters 205 is switched to the loss that remedies the pump outlet capacity in the circuit.But before the main pump/combination of filters that lost efficacy was repaired or be replaced, one of them associated circuitry was filtered the obstruction that becomes.In this case, when remedying line and filter 225 and provide a hydraulic pressure to substitute for plugged sereen, the filter redundancy of N+1+1 can make plugged sereen break from liquid line, so that clean or repair.Have again, preferably provide adaptive valve 215, check valve 217, manifold 219,221 etc. so that plugged sereen can be remedied line and filter 225 " instant exchange " (preferably automatic).As selection, those skilled in the art can expect that various line filter can be set in N+1 or the N+2 redundant array, and use one or more adaptive valves 215, stop valve 217, manifold 219,221 etc. links together.

When main filter F 6 and/or main pump P3 prepare once more to resume work (after checking, safeguard, repair or replacing), the said procedure simple reverse, the after-filter F12 and the pump P12 of appointment are picked out pumping system 10 "; current are connected once more; to recover pumping system 10 " normal operation, and do not need to close water slide.

Optionally, among described in the above arbitrary embodiment, pump P12 can provide the water of pressurization to the non-key terminal point of rotating 32, and such as an immobilising river, one at recursive filter or other unessential terminal point.Therefore, along with pump manifold valve PMV1 to the closing of PMV11 and valve AFV12, valve SV12, AFV13, APV12 and APV13 may be opened, and open pump P12.Pump P12 draws water from water reservoir 94 by valve SV12, filter F 12, valve AFV13, and pumps water to terminal point 32 by turns by valve APV12, pump manifold 20 and valve APV13.

Those skilled in the art will be readily appreciated that scope of the present invention allows to increase hydraulic pump system 10,10 ', 10 by other number of ways " redundant rank obtain interests in commercial and the application.Shown another embodiment among Figure 10.Have, for convenience of description and Short Description, those components identical are specified and no longer are repeated in this description with identical reference number again.In this case, for example, previously described embodiment's main pump P1 and valve PV1 are substituted by a parallel-connected pumps group 26, and main filter F 1 and valve FV1 are substituted by a shunt filter group 28.Certainly, any other main pump P2 is to P11 and service pump P12, and main filter F 2 to F11 and after-filter F12 can be substituted by such and joint group.If nozzle supplies water such as one of nozzle N1 waste supply canal very crucial part, then the also joint group of this pump and filter is very desirable.Embodiment among Figure 10 has illustrated provides special an assurance, the current that obtain nozzle N1 will can not be interrupted or destroyed.

Referring to Figure 10, pump P1 and P1 ' and valve EPV1, EPV1 ' are in parallel respectively in their waterexit ends separately at their suction side and valve PV1, PV1 ' separately.Similarly, filter F 1 and F1 ' and valve EFV1 and EFV1 ' are in parallel at water outlet separately at separately water inlet and valve FV1 and FV1 '.The preferably above-mentioned switch valve of these valves.In typical normal running, one of pump P1, P1 ' and one of filter F 1, F1 ' are picked out.Such as, pump P1 ' is that pent valve EPV1 ' and PV1 ' pick out, and filter F 1 ' the pent valve EFV1 ' and FV1 ' pick out.Certainly, in the normal running, when valve FMV1 and PMV1 closed, valve SV1, EFV1, FV1, EPV1 and PV1 opened.Therefore, the water of water reservoir 94 outflows is pumped out to nozzle N1 by filter F 1 and by pump P1.

If pump P1 lost efficacy or had to close, pump P1 ' can accept to provide sufficient water to supply to the responsibility of nozzle N1.This opens pump P1 ' by closing pump P1, throttle down EPV1 and PV1, and open valve EPV1 ' and PV1 ' finishes, thereby isolated pump P1 but do not destroy or interrupt the current of water slide.When pump P1 was ready to open once more, program described above was inverted, and pump P1 ' is picked out, water once more from pump P1 to nozzle N1, recover typical normal running, all these need not close water slide.This need shut pump P1 ', opens pump P1, shuts valve EPV1 ' and PV1 ', and opens valve EPV1 and PV1 finishes, so that to the current of water slide and be not destroyed or interrupt.Easily, closed if pump P1 and P1 ' lose efficacy or have to, service pump P12 (Fig. 7-9) can provide special redundancy.Under an interchangeable normal mode, pump P1 and P1 ' can be used simultaneously when pump rate reduces, if an inefficacy among pump P1 and the P1 ' maybe need be closed, each pump has the next nozzle N1 that independently supplies water of sufficient pump power.

In the same manner, maybe need to replace if filter F 1 is stopped up, filter F 1 ' can accept to provide sufficient filtered water to be given to the responsibility of nozzle N1.This opens valve EFV1 ' and FV1 ' and finishes by throttle down EFV1 and FV1, thus isolated filter F 1 but do not destroy or interrupt the current of water slide.When filter F1 prepares to reuse, program described above is inverted and filter F 1 ' is picked out, water once more from filter F 1 to nozzle N1, to recover typical normal operation, all these need not interrupt water channel.This need shut valve EFV1 ' and FV1 ', opens valve EFV1 and FV1 and realizes, so that be not destroyed or interrupt to the current of water slide.Easily, closed if filter F 1 and F1 ' lose efficacy or have to, after-filter F12 (as Fig. 7-9) can provide special redundancy.Under an alternative normal operation mode, filter F 1 and F1 ' can be used simultaneously.

Refer again to Figure 10, show pump P1, the P1 ' of two parallel connections and filter F 1, the F1 ' of two parallel connections, the use in parallel of any amount of pump and filter is apparent to those skilled in the art.In addition, pump P1 and P1 ' can be in parallel with a filter that is connected in series to the parallel-connected pumps group, and perhaps filter F 1 and F1 ' can and be concatenated into a pump by parallel connection.In addition, one and the joint group filter and the pump that can use to be serially connected with in each branch.Those skilled in the art can similarly revise in scope described in the invention up to many other.Redundant array of nozzles

As described earlier, shown in Fig. 7-9, nozzle system 13 comprises that a plurality of nozzle N1 are to N11.They are positioned at along the position that water slide is reserved in advance (Fig. 1) provides desirable momentum to water skier or water skiing vehicle to shift, and/or other desirable water skiing effect is provided.Owing to use pump described above and filter, lost efficacy if find one of them nozzle in the water channel by accident, become all or part of obstruction or by in the water or the leaf on water channel surface, withe or other refuses block.This situation, nozzle no longer can be brought into play required capacity and/or produce needed speed and the water yield and obtain needed effect.In this case, the water channel maintenance and repair of having to close.But, mention above, closing water channel is undesirable and disadvantageous situation, because the participant of water channel may become uneasy or lose patience when waiting for that water channel is repaired and replaced.And it is in a dilemma that the client on the slideway of closing by force can become when keeping in repair and restart.Can cause the decline of water skier's quantity and the reduction of slideway owner profit excessive fault time.

Correspondingly, additional features of the present invention and advantage are with a redundancy or accurate redundant nozzle system, overcome or alleviate these problems, as the diagram example in Figure 11 and 12.In embodiments of the present invention, nozzle system 13 is preferably accurate redundant configuration.Nozzle N1 one or more in the N11 can comprise a plurality of less nozzles or spout, by the nozzle N1 in Figure 11 and 12 as seen.Therefore, N1 preferably includes spout J11, J12, J13, J14 and J15, and their property preferably along the line are closely arranged.Accurate redundant spray configuration nozzle N1 further comprises a plurality of water flow control valve door FCV11 to FCV15, and each valve connects with the different spouts of nozzle N1.The flow of each spout of the nozzle N1 that flows through in these water flow control valve gate controls.Although for for simplicity, only shown the flow control valve of nozzle N1 among Figure 11 and Figure 12, nozzle N2 has identical structure to N11.Therefore, flow through spout J11 to the water flow of J15 respectively by being positioned at water flow control valve door FCV11, FCV12, FCV13, FCV14 and the FCV15 control of each spout J11 to the upper reaches of J15.

In the most preferred embodiment as Figure 11 and Figure 12, accurate redundant nozzle N11 has 5 spouts.Certainly, can increase or reduce to the quantity of the relevant spout of N11 with each accurate redundant nozzle N1.Further, each accurate redundant nozzle N1 can have the spout of varying number coupled to N11, best, accurate redundant nozzle N1 is a rectangle to the spout hole of N11, although other shape also can be used separately or in groups as circle, ellipse or polygon.The height of each spout hole is preferably from 1/2 centimetre to 40 centimetres, and width is from 4 centimetres to 40 centimetres.In addition, the pore-size of the spout of given nozzle can be inequality, as the spout J11 of the redundant nozzle N1 of standard to J15.Similarly, accurate redundant nozzle N1 also can be inequality to the pore-size of the spout of N11.As shown in figure 11, spout J11 can be adjusted by bolt hole plate 24 to the pore-size of J15.

Control valve FCV11 is to FCV15 butterfly valve preferably, although other valve such as Ball valve, angle valve door and needle-valve door also can use effectively.These water flow control valve doors preferably can be adjusted automatically by electromagnetism and/or hydrodynamic body regulator, at the current that equilibrium is provided normal in service.

In optimal operations pattern as shown in figure 12, when water flow control valve door FCV12 and FCV14 normally closed (close, with " deceive " or " " expression), water flow control valve door FCV11, FCV13 and FCV15 often open (open, with " in vain " or "〉＜" expression).Like this, spout J13 and J15 provide accurate redundant to nozzle N1, and therefore provide accurate redundant by idle capacity to system 13.Its advantage is that accurate redundant spout has reduced beyond thought all or part of obstruction on the water slide.

For example, with reference to Figure 12, in case one or more main injection jet J11, J13 and J15 stop up, flow control valve FCV12 and/or FCV14 just are opened to the setting of requirement, the water yield that need to allow flows out deposit spout J12 and/or J14, to compensate main injection jet J11, J13 and the J15 that blocks.Part or all of obstruction can be detected (discussing in the back) by pressure and/or flow transducer, in case partial blockage takes place for one or more main injection jet J11, J13 and J15, just need adjust flow control valve FCV11, FCV13 and FCV15 independently or with the opening degree associated ground of flow control valve FCV12 and/or FCV14.Flow control valve also can be adjusted according to pump water speed.By the deposit spout, as redundant spout J12 of the deposit of main redundant nozzle N1 and J14, the accurate redundancy that provides helps to allow water slide (as Fig. 1) relevant when spout stops up to move incessantly, obtains the maintenance or the maintenance that need up to affected spout.Certainly, all nozzle N1 can be configured according to the genuine characteristic of neatly independently to the main injection jet of N11 or the specific quantity and the specification of deposit spout.The special setting of water flow control valve door also can independently be carried out according to the requirement of water flow and the degree of spout obstruction.

Figure 13 has described another briefly and has had the redundant or accurate redundant interchangeable embodiment of attendant advantages of the present invention.In certain embodiments shown in Figure 13, pump P1 supplies water to one group of spout, and each spout is the part of individual nozzle.Those of ordinary skill in the art is readily appreciated that this pump can be integrated in any one pumping system 10,10 ' and 10 recited above to the configuration of spout ".Fig. 13 has shown the pump P1 that supplies water as spout JA1, JB2 and the JC3 of the part of nozzle NA, NB and NC to respectively, and pump P1 is Hydraulic pump system 10,10 ' or 10 preferably " main pump (Fig. 7 to 9).Nozzle NA, NB and NC are preferably along 30 ' (Fig. 1) close arrangement side by side partly of water slide.Flow by spout JA1, JB2 and JC3 is controlled by flow control valve VA1, VB2 and VC3 respectively.Similarly, be appreciated that pump P2 " supply water pump P3 to spout JA2, JB3 and JC1 " to spout JA3, JB1 and JC2 water supply (be clear, omitted connection among the figure).Pump among Figure 13, nozzle, spout and valve preferably as described here be close model.

In normal operation,, only can use the spout (not being whole) of some with reference to Figure 13.Concrete quantity can be according to size, characteristic and the desired effects of water slide.For example, if in normal operation, use spout JA1, JA3, JB2 and JC2, spout JA1 stops up, just can adjust one or more pump P2 " and P3 " pump water rate in, adjust respectively and link spray on every side such as flow control valve VA2, VB1 and the VC1 of JA2, JB2 and JC1, the current that reduced after losing efficacy with compensation spout JA1.Certainly, stop up, can adjust the flow control valve VA1 relevant together independently or with other flow control valve, obtain the flow and the flow velocity of enough water with JA1 if spout JA1 only is a part.

Under normal situation, all spouts can not reach maximum capacity and speed.The obstruction of any one spout can be by adjusting other flow control valve to increase flow.If for example spout JB3 stops up, lead to the loss that flow control valve VA3, the VB2 of spout on every side such as JA3, JB2 and JC3 and VC3 can adjust the water flow after losing efficacy with compensation spout JB2 simultaneously.Have again, stop up, can adjust the flow control valve VB2 relevant together independently or with other flow control valve, obtain enough normal water flows with JB2 if spout JB2 only is a part.

Therefore, the redundant array of nozzles of Figure 13 provides method, allows water slide under the situation that spout stops up, and continues operation incessantly, obtains due maintenance or maintenance up to this spout.Have, the special setting of the quantity of pump, nozzle, spout and configuration and flow control valve all is dependent on the characteristic of water slide independently, the degree that the position of the spout of obstruction and spout stop up again.Pressure and flow transducer

Optionally, in above-mentioned any one redundant pump, filter and nozzle array, each functional unit can comprise one or more relevant pressure transducers, shown in Figure 14 A-C.Therefore, shown in Figure 14 A, pressure transducer PSS1 places the suction side of water pump P 1, and pressure transducer PSD1 places the waterexit end of water pump P 1.Pressure transducer PSS1 and PSD1 are used for monitoring the performance of water pump P 1 and the flow of consequent head, and this information offers automatic control and the diagnostic system that the back will be discussed, and this system provides automatic diagnosis and " the instant exchange " of inefficacy water pump.Pressure transducer PSS1 and PSD1 can be getable any pressure-measuring instruments on the market, as pressure gauge, pressure transducer, stress sheet, barrier film table or the like.

Similarly, any one filter in redundant filter array can comprise one or more relevant pressure transducers, as shown in Figure 14B.Therefore, pressure transducer PSI1 places the suction side of filter F 1, and pressure transducer PSO1 places the waterexit end of filter F 1.Pressure transducer PSI1 and PSO1 are used for monitoring the pressure decline of filter F 1 to F12, and this information offers automatic control and the diagnostic system that the back will be discussed, and this system provides automatic diagnosis and " the instant exchange " of plugged sereen.Pressure transducer PSI1 and PSO1 can be getable any pressure-measuring instruments on the market, as pressure gauge, pressure transducer, stress sheet, barrier film table or the like.

If desired, can provide various sensors to monitor the performance of each nozzle N1 to N11.For example each nozzle N1 can comprise relevant pressure and/or flow transducer to N11, shown in Figure 14 A, at the water sucking mouth of nozzle monitoring head and flow velocity, Figure 14 C has shown a more complicated nozzle sensor system, and pressure and flow transducer place the suction side and the suction side of each group spout J11 to J15 of nozzle N1.Among each embodiment of Miao Shuing, pressure transducer PS1 can be getable any pressure-measuring instrument on the market, as pressure gauge, pressure transducer, stress sheet, barrier film table or the like in the above.Similarly, flow transducer FS1 can be getable any flowrate measuring tool on the market, as rotameter, Venturi tube measuring meter, static pressure surveymeter, tachometer, hot-wire gauge, magnetic flowmeter and mass flowmenter or the like.These can offer automatic control and diagnostic system by the information that pressure transducer and/or flow transducer provide, and diagnose possible inefficacy and correspondingly take correct compensation method.This control and diagnostic system will describe in detail below.Control/diagnostic system

As described above, if necessary, can provide pressure and flow transducer array corresponding to any one functional unit of redundant pump, filter and nozzle/spout array, so that can monitor to these parts.This control and diagnostic system are preferably monitored the effective parts of comings and goings and are automatically taked correct step.For example, Figure 15 has shown that this simply has the flow logic figure of the control diagnostic system 300 of characteristics of the present invention and advantage.Control logic discussed below and system can enroll program in suitable substance P LC, computer or related domain other control or logical circuit (electronics, fluid power or other).

Control system is since the 310th step, and whether inquiry startup water slide safety.This is inquired by the state of checking various wrong interrupt circuitries, operator's input, keyboard interlocking or the like and tests.If inquiry is not satisfied, then system carried out for the 312nd step, produced one and outputed signal to the operator, and indicating needs to remove water channel and replacement or check wrong interrupt circuitry.

Suppose that water channel is safe for starting, system can proceed to for the 314th step, waited for that operator input command is to start water slide.For example, this input can be start button, keyboard interlocking or the like.The present invention also can replace the more complicated computer control interlocking of use, remote access control or the like method.Be accepted in case start input, system just proceeded to for the 316th step, and PLC causes main initiating sequence, and in this sequence, the various pumps that constitute the water slide pumping system are activated with predetermined sequence and pattern, preferably each 10 second at interval.Optionally, the 318th step was the specific pump that the operator can adjust start-up mode and/or clearly select for operation by switch boards or other input interface.

In case selected specific pump in the 318th step, PLC is at the 320th step various pressure of inquiry and flow transducer (as above describing).These data (or the data through classifying or handling) are output to a display screen or remote data access mouth (the 324th step), can be monitored by the operator.This offers the remote monitoring station, for example by internet or directly modulator-demodulator connection.Therefore, if the operator checks or observes a sensed conditions, for example pressure or flow velocity, the functional unit that has shown the water slide system is out of joint, the operator can diagnose this problem, and takes correct method as break affected parts from pumping system, safeguards and/or repairs.Optionally, PLC can be programmed preface, with the pump of automatic diagnosis error condition as losing efficacy, and by taking correct method automatically to one or more remotely stimulating valves (as above describing) transmission excitation pulse.

PLC also usually monitors a series of wrong interrupt circuitry, for example is positioned at along emergency braking switch of each point of water slide or the like.These can and guarantee that the operator of the water skier's safety activates by one or more supervision water slides there.If water slide lost efficacy or the water skier is out of control, the operator who is for example observing can close brake switch, to close water slide or its part, so that he can take correct action.In the logic diagram of Figure 15, these brake switches provided in the 326th, 328 and 330 steps, corresponding to the zone 1,2 and 3 of appointment in the water slide.If any one generation in error condition 326,328 and 330, then according to step 336,338 and 340, pump can be in each zone 1,2 and 3 corresponding stopping.If there is not error condition to take place, system arrived for the 342nd step and circulates by each step.

Optionally, those skilled in the art will readily appreciate that and can use more complicated sensor and logic program, for example water skier's position transducer, velocity transducer or the like.The key component monitoring water skier's that these sensors can be used at water slide speed and the distance between them are to guarantee best Security and water skier's capacity.Position transducer can be used for triggering the intermittent operation of various injection nozzles, so that they only move in the time of the water skier.This can save lot of energy and cost.Extra useful I/O and systemic-function listed in following table 1:
