Description

A kind of method of the anti-inside and outside anti-mud back suction of blocking of drip irrigation below the surface system

Technical field；Irrigation equipment.

Background technique:

The inside and outside blocking and mud back suction in water dropper hole are always drip irrigation below the surface system background technology in practice principle Problem.

Background technique emphasizes particularly on different fields in terms of anti-inside and outside blocking, anti-mud back suction, respectively there is deficiency.Background technique has following Several method:

One, chemical attack dissolving method.Namely in irrigation water after filtering inanimate matter, caused by organic matter Attachment is deposited to drip hole blockage problem, is solved using acidic chemical corrosion dissolution method.

This method is theoretically explained logical, but the following defects and deficiencies exist in practice:

1, light concentration acid poor effect, weight concentration acid effect may be quite a lot of, but for large area trickle irrigation system engineering, not only Cost is too high, it is often more important that contaminated land.Applicant once solved the blockage problem of toilet shower nozzle, was first steeped with dense acetic acid Three days, then blown with tracheae high pressure, hydraulic pressure punching, it all can't resolve problem, steeped later with " lavatory is net " of toilet seat dirt It two days, just solves the problems, such as.

2, it can't resolve outer stifled problem, that is, vegetable hair radicula is protruded into because of the natural law for the water that becomes into water dropper hole.When So, if to say that acid solution can be dead capillary root-rot by force, soil is just dirty useless, and trickle irrigation just loses justice and anticipates.

3, it can't resolve mud back suction problem.Sour mud also can be by back suction again.

Two, back-pressure method.Namely by the structure of equipment, the Method of blockage removal of opposite direction pressure is carried out to water dropper hole.We The following defects and deficiencies exist for method:

Physics back-pressure is just if hole plug chemical attack of 1, dripping is all not all right? this method by pressure medium Matter only has water and air.

1., now discuss utilize hydraulic pressure.Irrigation water is applied with pressure, that is, is exactly the weight of equipment utilization " seesaw " formula Alternation principle is measured, two " water injection holes " (" jetting " two word can only be used here, because " jetting " just has the power of back-pressure) is carried out Alternately " jetting " of positive direction and opposite direction switches, that is, each " water injection hole ", a little while positive direction jetting, a little while instead Direction jetting.Problem is: in the world without perpetua mobilia, which switches the yak energy that disappear, it is, each is dripped The normal pressure in water hole is always larger than counter-pressure.So, all newborn blocking of the weeper single, normal pressure is big, small anti-of pressure Can pressure go the blocking that disappears?

Moreover when a weeper is intermittent stops jetting by gear, which is still contacted with water, moreover, because penetrating The water intermittent phase water phase of hole hole wall nearby is to stabilization, however more conducively mineral deposit.

As a whole, due to being mostly used weeper, the area that utilizes of hole wall is increased, this method, which has, delays aquatic blocking to imitate Fruit.

2., discuss utilize air pressure again.Certainly, this method can only be carried out when stopping and irrigating.Due to drip irrigation system terminal all It is close to soil, if carrying out air pump pressure to underground blank pipe, the weeper of water dropper will not generate high-speed flow, that is, not It can be better than chemical blocking-proof result.This method improves production cost.

2, back-pressure method does not prevent generation stifled outside, that is, blocks up outside caused by capillary root hydrotaxis.

3, back-pressure method does not prevent the generation of mud back suction.

Three, the anti-outer stifled and anti-mud back suction method of poromerics.Such as the material with non-woven fabrics etc.This method is in a short time There is good effect, but play negative bear quickly and answer:

1, the water dropper hole bigger than poromerics aperture can be blocked, and much less, poromerics is just blocked quickly.It is stifled Gluey particle of the plug thing in addition to inorganic, the organic matter in water, in more soil.Once poromerics is plugged, trickle irrigation just into It is capable not go down.

2, poromerics does not stop penetrating for capillary root.Capillary root in underground often has the cloth for penetrating that underground is buried in practice It is true.As long as pieces of cloth another side, there are water and fertilizer, the capillary root cap of this one side can attack the micropore to wear the cloth, big cloth is then supportted Micropore.It should be clear that closely knit soil again, the capillary radicula root cap of plant, which can also attack, to be worn, in addition poromerics.

3, the technological deficiency of the anti-mud back suction method of poromerics is to treat the symptoms short-term, but do not effect a permanent cure.Mud back suction " sheet " is drip irrigation system generated negative pressure after irrigation.This is also that application scheme sets about place.

Four, method stifled outside the anti-capillary root of mixed herbicide in water dropper plastics.This is a kind of external technical method.Its Effect does not work in trickle irrigation, because the burst size of herbicide is compared with water flux in plastics, on capillary root almost without influence. This method only when stopping irrigating, just works when hairiness radicula root cap is stretched over weeper nearby.

This method is in terms of anti-inside and outside blocking and anti-mud back suction, and there is also defects and deficiency:

1, at high cost.Currently, being only used for the high consumption such as golf course place.

2, since its weeding agent content gradually discharges, effect is very long becomes smaller for anti-outer blocking.It is single that outer ponding is prevented with regard to it, Only validity period is extended than domestic other methods.

3, for anti-interior blocking, that is, in water, the hole wall in water dropper hole caused by inorganic matter, organic matter is blocked, and incapability is Power.

4, helpless to anti-mud back suction phenomenon.

The technology of the present invention:

Technical solution of the present invention complies with the nature rule, by pure physics, associated method, treating both manifestation and root cause of disease utilize each other Anti- inside and outside blocking dropping head component drives and rotates with " the drill-bit type thin slice blade " of turbine consubstantiality by the pressure of supply water of weeper, The hole wall of continuous scraping water supply hole and weeper, physically reaches permanently the generation for preventing interior external blocking, and be associated Ground with settings such as intake valves for basseting of topography eminence setting, release groundwater supply be in charge of in stop generating after irrigating it is negative Pressure, it is therefore prevented that the generation of mud back suction.

The technical program can be within the same drip irrigation system material lifetime phase, the prior art of opposite simple function, while simultaneous It is standby to prevent inside and outside blocking, avoid being polluted with water chemistry, anti-mud back suction function, and effective life longest.

The attached drawing and explanation of citing.

(Fig. 1), anti-inside and outside blocking dropping head component example schematic:

Anti- inside and outside blocking dropping head component is the pressure of supply water by weeper, drives " the drill-bit type thin slice with turbine consubstantiality Blade " rotation, the hole wall of continuous scraping water supply hole and weeper physically reach permanently the hair for preventing interior external blocking It is raw.

Part A:

1, the weeper directly contacted with soil, and part " B " " 6 " --- the working position of " drill-bit type thin slice blade " It sets.The anti-blocking emitter component, inside have smaller aperture due for water end (W.E.) and larger aperture drip end two circular holes；I.e. hole " 1 " is answered Greatly than hole " 4 ", after " B " part turbine " 9 " is to " energy dissipating " effect of water jet power, slow down water speed out again, it is therefore prevented that " water hammer The generation of phenomenon ".

2, prevent the lower casing of inside and outside blocking dropping head component.Upper and lower shell material matter can be identical as the water supply pipe that underground fills.

It is 3, stable that " B " part --- turbine type scrapes the cross recess of cutting members.

4, the duct that jet stream is discharged from water supply pipe, and " B " part --- turbine type scrapes cutting members " drill-bit type thin slice knife The operating position of sword " " 8 ".Inside and outside installation is anti-when blocking dropping head component, duct " 4 " should be directed at the big drilling of water supply pipe.This is penetrated Discharge orifice is due to there is " the drill-bit type thin slice blade " of " B " part its " 8 " to protrude into, so the hole plane product of its circular hole is design usable floor area In addition the cross-sectional area of " drill-bit type thin slice blade ".

5, the screw hole of lower casing two parts in fixation " anti-inside and outside blocking dropping head component " shell.

12, the two-part positioning device of upper lower casing is convex-concave anastomotic structures, to guarantee the accurate fit of internal " 3 ", with true Protect " B " component energy flexible rotating.

13, arc thin slice corresponding with underground landfill water supply pipe outer diameter perimeter, has several and water supply pipe on its both sides The flexible sheets that extending direction is vertical, erects play flexible mat piece.It is not afraid of leak herein, as long as stablizing, leakage It can be blocked quickly at water；It is of course also possible to be in a word to want with anti-skidding, convenience with other flexible paddings or glue class.Arc The middle of the position of thin slice water supply hole in water supply pipe.

Part B: turbine type scrapes cutting members.

Its making material should be the good material of intensity, toughness, such as nylon material or stainless steel.

6, " drill-bit type thin slice blade ", it is corresponding with " 1 " of the part " A ".It is close, not extended too long with soil.

7, control turbine type scrapes circle wheel positioning element cutting members, corresponding with " 3 " of the part " A ".

8, " drill-bit type thin slice blade ", it is corresponding with " 4 " of the part " A ".It is considerably long to protrude into water system one end, to water supply The cotton-shaped organic matter being likely to occur in being in charge of plays stirring, chopping.

9, turbine disc.The disk and on a central axes, both ends be " drill-bit type thin slice blade ", be integral altogether Component can make fixed-direction, rotation with effect of inertia, " be bored with drive by the hydraulic pressure of jet stream in water supply pipe hole The scraping action of hair style thin slice blade ".

Turbine disc is just reduction of there are one effect from water supply pipe, i.e., jet stream is discharged from its " 4 " hole " A " Impulse force, along with its " 4 " aperture of " A " its " 1 " aperture ratio " A " is big, actually water dropper goes out water speed and reduces again, and jargon is disappearing In addition to water hammer.

C portion: turbine disc top view.

9, turbine disc.By the hydraulic pressure for water end (W.E.), fixed-direction, rotation with effect of inertia can be made, to drive The scraping action of " drill-bit type thin slice blade ".

10, the shaft of turbine disc.

11, the water conservancy diversion stress wall of " C " shape protrusion.Under the hydraulic action swept away from above, it can only make turning for fixed-direction It is dynamic.

Fig. 2, working space underground piping schematic diagram:

A, the prior art.

1, horizontal type fills water supply pipe.

2, water dropper in underground, upward is filled.

3, landfill is in underground, the vertical small water supply pipe of water dropper

B, application scheme.

1, horizontal type fills water supply pipe.

4, horizontal type landfill water supply pipe is located at the air inlet pipe of topography eminence basseted, and top is provided with one-way movable Valve plate, when irrigating, hydraulic pressure closes the one-way movable valve plate；When stopping irrigating, the negative pressure that middle generation is in charge of in underground will be unidirectional The suction of movable valve plate is opened, instant-free groundwater supply be in charge of in negative pressure, it is therefore prevented that the water dropper mud back suction phenomenon of underground.

5, the terminal of each unit water supply pipe of underground landfill, is arranged the exhaust valve to elevate above the soil, effect is to start to fill At the beginning of irrigating, the gas in being in charge of is discharged in time.Under normal circumstances, the exhaust pipe should be higher than that water inlet manifold, it is ensured that when irrigation and When be vented, water-tight, timely air inlet anti-negative pressure when stopping filling.

The water inlet manifold of every unit and water supply pipe tail end height difference are not too large, then big Shi Yingfen secondary units, so not It must worry that exhasut valve stem is excessively high.

6, " the anti-inside and outside blocking dropping head component " of horizontal type water supply pipe side is set.

Embodiment:

One, external formula blocking in preventing.

1, the former source of Nei Shengshi blocking.Different water sources can generate the object for easily causing drip hole blocking in different ways Matter, have instant irrigation water after filtering, the inorganic sediment and organic generation granule that still have；Also stopping irrigates Afterwards, since air in underground piping, temperature, moisture are suitable for the organic cotton-shaped attachment generated for a long time, once being taken off from being in charge of on wall It falls, is easiest to that drip hole is caused to block, as the thrombus of people generates.

2, under crop field horizontal type water supply pipe the depth of burying.The prior art is that vertical water dropper is arranged in horizontal type water supply pipe It is in charge of, thus the depth buried will be in charge of.In fact, it can not play that operation is convenient and protection drip irrigation facilities in this way, because of the more perpendicular Formula water dropper is just in shallow soil hereinafter, be equivalent to the depth for improving landfill.

The more vertical water dropper water supply pipe (Fig. 2), it is not only unhelpful, it is harmful instead, it be easy to cause after stopping filling in managing and generates Negative pressure causes the generation (being hereafter described in detail) of mud back suction.

The technical program be not provided with it is horizontal bury in water supply pipe it is vertical it is small be in charge of, but by the embedded depth of horizontal type water supply pipe Degree is placed on mellow soil layer bottom；Apopore in horizontal type water supply pipe, scene drilling, aperture however influence pressure of supply water macropore Diameter, diameter should be more than 5MM, it is therefore an objective to the initial water pressure of " anti-inside and outside blocking dropping head component " should not be rung, to ensure " anti-inside and outside blocking Hydraulic pressure of the water dropper component " weeper to " turbine disc ".

The control of trickle irrigation water, the apopore aperture not in horizontal type water supply pipe, and in " anti-inside and outside blocking dropping head portion The aperture of part " interior " 4 " and the hydraulic pressure of total irrigation system.

3, the in-site installation of " anti-inside and outside blocking dropping head component ".

First of all, it is necessary to using qualified product is examined through producer.

1., punch in horizontal type water supply pipe.Horizontal type water supply pipe put cloth it is good after, design interval location side by (without Right above being), the macropore of hole diameter 5MM or more.

2., hole that will be bored in " 4 " alignment horizontal type water supply pipe of intact " anti-inside and outside blocking dropping head component ", will be upper and lower Shell is combined, and uses screw-driving；Just in case sliding, is infused and seeped with various rapid-hardening glues, is fixed temporarily, for example squeeze into 502 fast solid glue liquid.Once " anti-inside and outside blocking dropping head component " embedment underground, joint portion will be blocked viscous real gradually.

After " the anti-inside and outside blocking dropping head component " of each innings of section engineering is installed, to be tested by trickle irrigation, it is ensured that " in anti- After turbine rotation in outer blocking dropping head component ", that is, " drill-bit type thin slice blade " rotation, landfill work just can be carried out.

Since " drill-bit type thin slice blade " constantly rotates scraping, either inorganic matter precipitating or the deposition of organic matter, In the buried material lifetime phase, Nei Shengshi blocking will not occur.

Inorganic matter precipitating is anti-blocking, mainly in the hole wall of weeper, under the continuous scraping of " drill-bit type thin slice blade ", no Inorganic matter blocking can occur.

Organic cotton-shaped piece that falls off of Organic Material Blocking in managing, the mainly Nell wall of long-time pipe attachment.In " anti-inside and outside blocking In " 4 " hole in water dropper component ", too long " drill-bit type thin slice blade ", the cavity in the water supply pipe side of " 4 " have been protruded into Interior, organic cotton-shaped piece that falls off constantly is stirred and is shredded by " drill-bit type thin slice blade " in water, eventually with tiny volume quilt Water flow extrudes.

4, external formula is dripped hole plug, the mainly vegetable hair radicula hydrotaxis blocking of protruding into weeper formation.Plant The growth of capillary root extends, and is that " elongation zone " cell behind root cap tip divides rapidly completion, part thereafter can only be past It is thick long, will not extend again, should " elongation zone " generally there was only 2 --- 3MM long, once should " elongation zone " be cut off, then this root is again It is also impossible to extend." the drill-bit type thin slice blade " of the technical program is as long as once cut off the " elongation of the capillary root Area ", just terminate this root it is lifelong protrude into drip hole.

So the technical program is in terms of preventing external formula blocking, compared with dissolving in herbicide in external plastics, no matter from ring Conformal degree, or from service life angle, there is significant progress.

Two, anti-mud back suction method and implementation.

The root of mud back suction:

The main reason for mud suck-back is the structure that vertical water dropper is in charge of in drip irrigation system, and when the water supply of underground distribution It is in charge of and the biggish variation of height occurs with landform tendency.After stopping supplying water, in system remaining water it is inevitable to topography relatively Low place is unrestrained to seep, and in drip irrigation system vertical water dropper be in charge of and the higher office's section of topography be in charge of in residual water level it is also inevitable It is very long to topography it is low be in charge of stream drop, this results in the vertical office's section for being in charge of part and high-land and is in charge of middle generation negative pressure, due to Trickle irrigation just is carried out, water dropper is all nearby high-moisture soil, so being easy to cause mud back suction.

Solution:

1, remove the structure (" A " of Fig. 2 its " 3 ") that vertical water dropper is in charge of, water dropper is set up directly on and is in charge of on side (figure 2 " B " its " 6 ").In fact, the prior art is not scientific by the mode for being in charge of buried distribution: its original reason is to facilitate farming, And in practicing, there are a lot of vertical water dropper upright pipe structures (Fig. 2 its " A ") since each is in charge of, the depth of irrigation system landfill Degree, the depth (" A " of Fig. 2 its " 2 ") that substantially only water dropper fills.It is that will not be in charge of top at every to make machine in operation practice Tool farming industry.If crop be it is perennial woody, this is in charge of should be on the plantation row of crop；If crop is annual Grass, then the confession be in charge of top should be protrude ground ground ridge.

Nearby temperature is organic to accelerate aerobic mushroom to decompose there are also the effect of physical protection water dropper, raising water dropper for ground ridge The effect of object, anti-emitter clogging.

Remove it is vertical be in charge of structure, increase be in charge of buried scale, also reduce the cost of engineering certainly, moreover, because It is in charge of without vertical water dropper and deep trench, it will be conveniently when to upper installation " anti-inside and outside blocking dropping head component " is in charge of It is more.

The depth for filling ditch, generally should be depending on the thickness of mellow soil layer, the density of soil and tillage method.Mellow soil layer Thickness can not be deeper than 30CM；Mellow soil layer is thin, can not be shallower than 20CM.The soil thin for mellow soil layer, should be relatively buried point Pipe can promote increasing for raw soil layer organic matter since the root system of plant becomes the attribute of water, promote what soil mellow soil layer thickeied to become Gesture.

2, after the filling type water supply pipe of each unit has been distributed, on each set distance point being in charge of, installation is " anti- Inside and outside blocking dropping head component ".

1., first check whether " anti-inside and outside blocking dropping head component " component complete.

2., by the side for being in charge of installation position, drill straight diameter is greater than the hole of 5MM, and effect is not reduce " anti-inside and outside blocking dropping head portion The hydraulic pressure in its " 4 " hole of part " " A ", it is ensured that the turbine of " B " part is rushed and rotated by water.It should be noted that residue not drop into water supply when drilling In being in charge of.In fact, residue can only squeeze out outward due to the helical structure of drill bit.

3., the upper and lower part of " anti-inside and outside blocking dropping head component " is enclosed in bore position, paying attention to will be " anti-inside and outside stifled The big drilling in " drill-bit type thin slice blade " alignment water supply pipe in plug water dropper component ".

4., close the upper and lower two parts of " anti-inside and outside blocking dropping head component ", pays attention to that " 12 " convex-concave on alignment two parts is fixed Site；Tighten fixed screw.

5., just in case fixed screw has the sliding phenomenon of pine after tightening, instiled with spare various rapid hardening glues.It is preferably used with It is in charge of the liquid glue that plastic material matches.

3, when " anti-inside and outside blocking dropping head component " of each unit after the installation is completed, to carry out examination water program, mainly see every Whether " drill-bit type thin slice blade " in one " anti-inside and outside blocking dropping head component " rotates.

4, the advantage of trickle irrigation is to be suitble to uniform water-saving irrigation under the conditions of ploughing uneven.In case of trickle irrigation topography height rises Present situation is lied prostrate, also profile-followed tendency in this case need to be in the highest of the higher office's section of each topography for certain inbuilt water supply pipe Place, the intake valve that setting one is elevated above the soil are negative because producing in the water supply pipe of setting intake valve office section when stopping pouring water Pressure, causes the intake valve air inlet, newly generated negative pressure in the side's of releasing water supply pipe, it is therefore prevented that the mud back suction of water dropper.

There is one-way fashion flapper in the intake valve, when water presses outward in water supply pipe, which is closed；When When water is inwardly shunk back in water supply pipe, negative pressure suction of the flapper within be in charge of is opened due to air inlet, it is therefore prevented that the mud of water dropper is anti- It inhales.

The tail end of each buried water supply pipe of unit, if an exhaust basseted is closed, effect is at the beginning of starting irrigation, and When discharge water supply pipe in gas.Under normal circumstances, the exhaust pipe should be higher than that water inlet manifold, to prevent metalling run out.

5, process is filled.It first uses relatively wet soil pressure to live " anti-inside and outside blocking dropping head component ", after stable be in charge of, then fills out It buries.

Three, auxiliary aerobe.

Will overturning repeatedly, well-done farmyard manure, is soaked in water, then by the dilution of its soaking water, multistage filtering.It is this Not only contain sufficient inorganic fertilizer in leachate, but also contains a large amount of aerophile bacteriums.Its dilution is added water, day is not being lacked Rain stops the filling phase, feeds the groundwater supply system of trickle irrigation, it is allowed to survive, multiply in groundwater supply is in charge of, inside and outside water dropper component, It is not only advantageous to plant growth, soil-ripening, and groundwater supply can be in charge of organic with the deposition in water dropper component on wall Object is further broken into the inorganic matter for being dissolved in water, plays the role of clearing up pipeline, anti-interior raw type blocking.

Originally, dripping irrigation was typically all to supply water, fertilising, carry out simultaneously.

Auxiliary aerobe operation, is separated by 2 --- it is advisable within 3 years.
