Description of drawings
Though any other form also can fall within the scope of the invention, following only with the mode accompanying drawings preferred form of the present invention of example, in the accompanying drawings:
Fig. 1 represents the schematic side elevation of the preferred liquid level regulation apparatus according to the present invention; With
Fig. 2 represents another schematic side elevation of the preferred liquid level regulation apparatus according to the present invention.
The specific embodiment
Referring to accompanying drawing, but be used for the producing fluid level of relative dividing plate second side, the device of regulating the liquid level of dividing plate first side is expressed as water surface elevation adjuster (10) in the drawings.The water surface elevation adjuster device is arranged on the dividing plate of floodgate (12) form.Be the floodgate of this device of fabrication and installation, the core of floodgate is removed to form passage (14) (generally being circular channel).
What be installed in floodgate first side is the outlet conduit of outlet (16) form.This outlet has tubaeform or flanged end (18), and end (18) are fastened to floodgate by bolt (20) makes the tube opening of end aim at passage (14).The liquid level of dividing plate outlet side is determined in the position of pipe (16) opposite end.
In the embodiment in figure 1, the height of outlet (22) can change (for example, can will manage extension (24) by the negative and positive fit structure and be connected to outlet) by the position of determining one or more pipe extensions (24) on it.As shown in the figure, when extension not being set, low water stage LWL is limited by this outlet, but when many extensions were connected, new outlet (22 ') was defined, so can set high water level HWL.Can realize relocating of outlet (22) by outlet (16) is stretched.
In second embodiment shown in Figure 2, outlet (16) can move by (pivotally), and selected position shown in a plurality of, and the flexible wavy fairlead (32) of this Guan Jing as described below is connected to floodgate (12) at passage (14).
Some feature in these features of second embodiment is relevant with the inlet tube (30) of following first embodiment that specifies, for for purpose of brevity, no longer these features is repeated below.In Fig. 2, identical label is represented similar or identical parts.
In any case it is most important that the controllability of outlet is regulated for the liquid level of dividing plate first side.
Referring again to Fig. 1, be installed to dividing plate (12) and the dividing plate screen (26) that stretches out from this dividing plate around outlet (22) (on low and the orientation that stretches or pivotally rotate), enter pipeline or discharge from import from pipeline to avoid floating thing.Usually, this dividing plate screen constitutes by electroplating steel mesh, stainless (steel) wire etc.In another preferred embodiment, dividing plate screen (26) can be replaced or be replenished by the filter mantle (27) that is installed in the outlet (22) with identical function.In a further embodiment, the structure of dividing plate screen and filter mantle also can be last or overlapping on every side at inlet tube (30), for for purpose of brevity, no longer repeats here.But, in any case this screen being provided with on inlet tube (30) or outlet (22) all can be avoided the discharge of floating thing or enter two pipelines.
Be installed on relative (second) side on the floodgate (12) is removable (rotor motion) inlet tube (30).Removable inlet tube can be selected a plurality of positions, and three positions wherein are schematically illustrated as A, B, C in Fig. 1.The usually corresponding low morning and evening tides water level of position A, the corresponding high tidal level of position B, position C is corresponding flood tide nighttide water level (as waterline a, b, c schematically shown in).Inlet tube (30) is connected to floodgate (12) through the wavy fairlead of flexibility (32) at passage (14).Usually, this fairlead by polymer (for example, synthetic or natural rubber) material make, so that maximum pliability and long-term durability to be provided.Tubaeform or the flange-shape end of fairlead is crushed on below the circular mounting plate (34) usually, and installing plate (34) is fastened to floodgate (12) by bolt (20), to provide liquid seal at this place.The opposite end of fairlead is around inlet tube (30) and/or by the gluing inlet tube (30) of receiving.
Inlet tube generally has the elbow (36) that is mounted or is formed on the entrance point of opening (38).This elbow preferably guarantees when the liquid level of normal regulating sluice reveal in the fluid around inlet part (38) is immersed at least.Most desirably, under most adjusting liquid level situation, the whole or overwhelming majority of entrance point should be immersed in the liquid, enter pipeline to prevent floating thing.In addition, be the back pressure of avoiding being produced by the gas of being held back (being generally air) when the complete submergence of entrance point, perforate (40) is arranged in the elbow (36) discharging this gas pressure, thereby keeps the flow regime of passing pipeline.
Relocatable floating drum (42) be installed in that elbow (36) is gone up or near.Floating drum is secured to the external surface of pipe (30) through connecting band (44), and connecting band (44) can be adjustable clamp (such as, hose clamp), clamp, fixed strip, cingulum or any other suitable regulated bindiny mechanism.So floating drum can be positioned in each position and change the water level that the fluid that enters import flows and then changes the dividing plate both sides along inlet tube.Floating drum also helps to change the kinetic characteristic of pipe (30).For example, when floating drum is positioned at the elbow district of pipe or when neighbouring, the import (38) of pipe (30) can partly or wholly be raised on every side on the liquid level, so the confined liquid flow ipe.But when floating drum was little by little mobile along inlet pipeline, import can be by submergence more or less, and flowing is changed, thereby the water level of both sides changes.For different application (for example, different fluid mass and density, different pipeline motion response time requirement etc.), the position of floating drum, buoyant characteristics and size also can change.
Similarly structure also can be made into relevantly with outlet among second embodiment shown in Figure 2, and the outlet among Fig. 2 is movably (pivotable).The relocatable floating drum can be secured to the external surface of outlet all places, impact suddenly or confined liquid backflow inlet pipe road during flash flood to regulate by its liquid flow and for example producing.
The horizontal of (for example, along with the rising and the decline of water level on every side) inlet tube moves when rising and descend in order to avoid, and pair of parallel guide peg (46) is installed to floodgate and stretches out at the opposite side of managing (30), as shown in the figure.So this bar restriction conduit is towards the motion (preventing its transverse movement) of vertical plane.Be mounted and what stretch between guide peg is laterally brake bar (48) and (50) up and down, they limit the last vertical stroke (position C) and the following vertical stroke (position A) of this pipe (30).Usually these quilts in advance scale and with minimum and maximum liquid level (for example, morning and evening tides or the flood level) correspondence of floodgate inlet side.Similarly structure also can be employed relatively with the outlet among these embodiment, and said here outlet is movably (pivotable).
In addition, shown in the C of position, maximum stage C can be unusual or irregular water level, and in this case, it is desirable not making any liquid be sent to opposite side from a side of floodgate.So entrance point (38) is positioned on this water level.
Inlet tube can comprise flap valve (52), and the liquid that only allows that flap valve (52) is provided with flows to outlet from inlet tube.This can be provided with locking system in some of this device used, for example make the predetermined level of outlet side can keep to such an extent that be higher than the liquid level of inlet side.For example, in the coastal area of great changes will take place morning and evening tides, it is useful that the water arrangement for adjusting height is set, so that water remains on the permanent position at the outlet side that has shell ship (hulled boat) to berth, and seawater or river water level descend at inlet side.So,, the floatability all the time of shell ship is arranged on the water no matter how the local morning and evening tides of hull " stranded " is changed.Flap valve also can be used for the restricting export liquid of side mixes with the liquid of inlet side, particularly, can be used for following situation: will be for example acid FIX CHARGE RATE ABOUT THE WASTE water outlet or other industry water and river or underground moisture from or for example fresh water is separated with seawater when being favourable.
It is agricultural irrigation that typical case of the present invention uses.In this case, inlet tube can corresponding morning and evening tides water body, and outlet can corresponding irrigation canal (irrigation flow way) etc.Water is from the morning and evening tides side flow to fixing water level side.When import is lower than when outlet, can produce from swimming over to the flowing of upstream (for example because the quality of inlet side liquid or pressure greater than the quality or the pressure of outlet side liquid) down.But, if desired, this situation can be opposite.Flow and the height of water can and use above-mentioned movable exit pipe to regulate by mobile relocatable floating drum, increase and decrease extension.
In various application, in a single day device is provided with and demarcates, just begin automatic operation, does not need to be paid close attention to again, removes nonparametric and changes (parameter then needs to demarcate again when changing).In addition, floodgate can be separated from each other water body, and this water body is at outlet side contaminated (contaminated earth in for example, by water body riverbed B).Common contaminated water body source results from mining industry, and wherein rock of Bao Luing and soil can make (for example, being caused by bisulphate salt solution) such as water acidifications.Under any circumstance, this preferred embodiment can make contaminated water body be replenished.
This device also can be used for others, for example, and water in the fishway (culture fishery) and the pond of the growing seedlings exchange exchange of fish and food (and even).In fact, as long as in a side (and even both sides) of floodgate, dividing plate or partition wall SEA LEVEL VARIATION is arranged, this device just can any pattern automatically be operated.
Usually, make the entrance and exit pipe, particularly use the uvioresistant plastics with low pressure plastic pipe and tube.Can use inside catoptrical pipe, to impel the contrary pipe of fish on because fish is inactive when swimming the dark channel that water is into arranged.By using the organic glass section, also can make this pipe be printing opacity or part printing opacity, swim across to impel fish again.The diameter of pipe or tube changes based on the water yield that transmits, and wall thickness is set according to the low-voltage standards of routine.
Usually, the diameter of flexible fairlead is corresponding with pipe and have sufficient flexibility and move 10 °-90 ° with (laterally) at least.Fairlead forms inner joint on it is installed to the part of inlet tube.
Can be as described above by cutting a core that equates with pipe diameter, drilling bolt hole, then flexible fairlead and inlet tube, outlet being assembled and applying pressure plate and with this device existing floodgate of repacking and dividing plate optionally when considering hydraulic pressure.But, this device also can be configured to a new unit.
Usually, the guide peg that zinc-plated steel or stainless steel forms, and mesh screen.When water when inlet tube flows to outlet, zinc-plated mesh screen is as strainer, so need cleaned at regular intervals or emptying.
Transmit for a large amount of water, can use larger-diameter pipe (that is, device can be scaled as requested or be amplified), also can be with the multiple arrangement unit across the floodgate setting.
Should be understood that if any prior art is hereby incorporated by reference, so this reference is in Australia or any other country and be not equal to the general common practise of admitting in these information formation this areas.
Though in conjunction with a plurality of preferred embodiments the present invention has been described, obviously the present invention also can be embodied as many other forms.
