Abstract

The invention discloses an anti-clogging capillary drip irrigation emitter with a flat plate superimposition structure. On basis of a physical phenomenon that water in a narrow slit rises up under the action of capillary force, at least two n-shaped flat plates are used to form a stable narrow slit to enable water in a container to move upwards and diffuse outside the container along the narrow slit, and then the balance between gravity of water and surface tension of the narrow slit to water is broken, as a result, the required drip irrigation speed is obtained, water is enabled to move fromthe inside of the container to the outside of the container at a low speed, and water-saving irrigation is performed on a targeted plant. The capillary force only works on water and has no effect on solids such as sandy soil, and meanwhile, the uninterrupted drip irrigation scheme is adopted, so that salt substances are diluted continuously to prevent salt accumulation; and further, a micro waterdelivery device is placed in a working environment insolated from sunlight, so that microbes are prevented from breeding. In this way, the capillary drip irrigation emitter can be prevented from being clogged by sandy soil, salt and microbes, and meanwhile, a super-large size drip irrigation system free from limitation of pressure attenuation can be constructed by utilizing the theory of communicating vessels.

Description

A kind of anti-obstruction capillary drip irrigation emitter of dull and stereotyped iterative structure

Technical field

The present invention relates to a kind of drip irrigation emitter, specifically is a kind of anti-obstruction capillary drip irrigation emitter of dull and stereotyped iterative structure, can realize water in the container to outside move outside container with slow speed, carry out the function of water-saving irrigation to target plant.

Background technology

Human society is for the needs of productive life, various water conservancy irrigation engineerings have been invented, but because water resource is in short supply day by day, force people to adopt the irrigation method of more saving, Israelis Si Maiha. rich Lars father and son has invented drip irrigation technique especially, for major contribution has been made in the water-saving irrigation of human society.

Drip irrigation is to utilize the special equipment of a cover, press water (can by water pump pressurization or the pressure that utilizes the landform drop to produce) is arranged, after filtering, by water transfer pipe networks at different levels to water dropper, water from water dropper in the drop mode, drop by drop directly splash into the crop rhizosphere topsoil lentamente, after water droplet splashes into soil, infiltrate by gravity, below water dropper, form very little saturation region. and to around diffuse to the crop root ecumene gradually irrigation method be called drip irrigation, because drip irrigation is to use a spot of water, and be the soil of moistening crop root mobile layer, so drip irrigation is called the part again and pours water.

Drip irrigation has water-saving, it is even, energy-conservation to irrigate, the adaptability of soil and landform is strong, volume increase, saving of labor, make things convenient for advantage such as farm work.

But drip irrigation also has its limitation, is embodied in:

Water dropper stops up the obstruction that very easily causes water dropper in the use, mainly be by suspension (sand and mud), dissolving salt (mainly being carbonate), iron rust, other oxides and organic matter do not cause, water dropper stops up the uniformity that main influence is poured water, and when serious whole system is scrapped.

When salt accumulation was irrigated at the arid area higher water of employing salt content, salt branch produced accumulation at water dropper humidification zones periphery, and these salinities are easy to be arrived the crop root zone by drip washing, when seed germinates in the high salt concentration subregion, can bring adverse consequences.

Influence the Root Distribution of root thing for perennial fruit tree, root density increases near the water dropper position, but not the humid region root system is supplied its growth and can be affected because can not get sufficient moisture, especially in the arid and semi-arid area, there are much relations the distribution of root system and water dropper position, few irrigation method of irritating diligent filling can cause the tree root distribution to shoal, and the area bigger at wind-force may produce the harm of uprooting.

The cost of investment height, administrative skill requires high, want dynamic energy requirement, the attenuation effect of water pressure makes that effective work area is little, the susceptible to plugging difficult problem of drip irrigation pore volume fails to capture so far simultaneously, make the drip irrigation equipment lost of life, the play of operation and maintenance cost is risen, and numerous reasons orders have the large tracts of land of pressing drip irrigation to promote to be subjected to very big restriction.

Water resource in short supply day by day, the running down of ecotope forces people to make up and promotes more and save, and river construction more efficiently and method solve the lack of water quagmire.

For this reason, need not driven by energy if can design a cover, more meet the plant growth rhythm, the drip irrigation system of overlong service life can be made bigger contribution for ecological construction undoubtedly.

Summary of the invention

At first, the physical phenomenon when analyzing the drip irrigation equipment operation, we can be generalized into it water filter element of flowing through from the water source, pressure-producing part, pipeline is slowly dripped outside pipeline by micropore in the pipeline at last, fall a near process of the soil of root system of plant, produce a main cause of stopping up, because people are dripped speed slowly in order to pursue, the micro-pore diameter of making at pipeline is too little exactly, the sandy soil of water the inside, mineral salt, impurity such as microorganism are stuck in the micropore and result in blockage under the effect of pressure.

How to make water run to the destination with the needed slow speed of people from a carrier and be unlikely to again to interrupt, can be described as the core content of drip irrigation technique.

This defective takes place to stop up easily for overcoming drip irrigation emitter, the present invention designs a kind of capillary drip irrigation emitter, it is characterized in that, at least one block of " n " the bright and clean hard plate material of shape, trickle polishing scratch or recessed poor can made at planar surface, can not do yet, the bright and clean hard plate material of another piece " n " shape can not done make trickle polishing scratch or recessed poor at planar surface yet, plate stack is lumped together and be fixedly clamped, form narrow gap between the plate material, constitute little water delivery device, and little water delivery device is straddled at the container edge, one end of little water delivery device immerses in the interior water of container, and other end correspondence is positioned over the outer captation of container.

Water in the container is subjected to the upwards operation of effect of capillary force in the narrow gap that two superimposed places of the bright and clean hard plate material of " n " shape form, and outside narrow gap diffuses to container an end, under the effect of gravity, operation downwards, this moment, the water of an end outside container was subjected to gravity and narrow gap to its surface tension effects, as long as make gravity that the water in the narrow gap is subjected to greater than surface tension, water just can be broken through the surface tension of narrow gap, drop to outside the container, can realize the purpose that water moves outside the past container in container.

In this capillary drip irrigation emitter, because the passage that water moves outside the past container in container is narrow gap rather than micropore, making the power of water motion is that narrow gap is to capillary force rather than the pressure of water, and capillary force only works to water, then inoperative to solids such as sandy soil, so solved the generation disruption that water slowly moves in the container effectively to container outside.

Making trickle polishing scratch or recessed poor effect on bright and clean plate material surface is to rise in order to eliminate water capillary in narrow gap, the partition bubble that forms in the diffusion process, and reduce the surface tension that water is subjected in the decline process, and can be so that the more miniaturization of little water delivery device, economization.

But, the operation level of the capillary drip irrigation emitter of working it out like this can be subjected to hard plate material manufacturing process, the influence of material character, it is bigger to be embodied in produced every cover capillary drip irrigation emitter speed of dropping water error, be unfavorable for using in a unified manner, the chemical substance in the water can influence capillary drip irrigation emitter efficient and life-span with little water delivery device generation chemical reaction.

For solving this a series of problems, a kind of modified capillary drip irrigation emitter is proposed, it is characterized in that, Fig. 1 is little water delivery device structural representation, at least one " n " shape float flat glass (2), make trickle polishing scratch or recessed poor at " n " shape float flat glass (2), be respectively capillary trace (3), operation trace (4), gravity trace (5), and be superimposed together and be fixedly clamped with another piece " n " shape float flat glass (1), and make the capillary trace, move trace, the gravity trace, place the narrow gap that forms between the plate material, constitute little water delivery device (7), Fig. 2 is capillary drip irrigation emitter structural representation, and little water delivery device (7) is straddled edge in container (6), capillary trace one end is immersed in the interior water of container, and gravity trace one end correspondence is positioned over the outer captation (10) of container.

In order to make the capillary drip irrigation emitter be expanded into system, we also arrange water supplement port (8) in order to moisturizing at container bottom or near bottom position, and container and upper edge, captation joint portion slightly lower arrange maximum water level (11) in order to the reference work water level.

Its course of work is as follows: water enters container (6) from water supplement port (8), when the narrow gap of little water delivery device is immersed in the water level rising, water is subjected to the upwards operation of effect of capillary force in narrow gap, and diffuse to gravity trace one end along narrow gap, under the effect of gravity, break through the surface tension of narrow gap, be dropped into captation (10), via conduit (9) plant (12) is carried out drip irrigation, maximum water level (11) be the reference work water level, the poor joint portion of its position container and funnel is lower slightly, as long as guaranteed water level is lower than the highest working water level line, just can avoid water to overflow from funnel is poor, cause waste.

Capillary trace, the effect of operation trace are to eliminate water capillary in narrow gap to rise, the partition bubble that forms in the diffusion process, and the effect of gravity trace is to reduce the surface tension that water is subjected in the decline process, can be so that little water delivery device miniaturization, economization.

Change the capillary trace, the operation trace, the number of gravity trace, thickness can make little water delivery device obtain different water droplet dropleting speeds, and being convenient to make different operating needs the capillary drip irrigation emitter.

The water delivery device unit volume is very little, so several or the little water delivery device of dozens of can be placed in the same capillary drip irrigation emitter simultaneously, improves the equipment service efficiency.

Owing to selected the specifications of quality, the float flat glass that chemical property is stable is made little water delivery device, if the aluminium alloy that chemical property is stable after the use passivation is made the water container of capillary drip irrigation emitter, be equipped with lid again, allow little water delivery device be in the working environment isolated with light, make the capillary drip irrigation emitter avoid water evaporates and microbial growth, can make the speed of dropping water equilibrium of every cover capillary drip irrigation emitter, be convenient to use in a unified manner, life-span length exceedes a century, effectively reduces annual use cost and the repeated construction cost of equipment.

The effect of single drip irrigation emitter is very little, if numerous drip irrigation emitters is formed system, just can make the bigger effectiveness of drip irrigation emitter performance.For this reason, design a kind of water level distributor box, Fig. 3 is water level distributor box structural representation, by casing (13), dividing plate (14) ensures case (15), distributor box (16), ball-cock assembly (17), water inlet (18), water-distributing gap (19), connected entrance (20), limit for height waterline (21) is formed.

Fig. 4 is capillary drip irrigation system structural representation, link to each other with water source (22) with the water inlet of pipeline with first order water level distributor (23), connected entrance links to each other with communicating pipe (25) with the water supplement port that is positioned at same horizontal numerous capillary drip irrigation emitters (24), and the limit for height waterline that makes the water level distributor is in same horizontal line with maximum water level with each capillary drip irrigation emitter, water-distributing gap links to each other with the water inlet of second level water level distributor, the connected entrance of second level water level distributor links to each other with communicating pipe with the water supplement port that is positioned at same horizontal numerous capillary drip irrigation emitters, just can form the capillary drip irrigation system.

It is as follows that capillary is dripped the drip irrigation system course of work: because the distribution reservoir water level of first order water level distributor is low, ball-cock assembly is in open mode, water enters the guarantee case from water inlet through ball-cock assembly, according to law of connected vessels, the numerous capillary drip irrigation emitters that are on the same horizontal line with it obtain contour water level, begin to carry out drip irrigation for plant, when ensureing that the case water level continues to rise, when being higher than dividing plate, water will be from ensureing that case overflows, enter distribution reservoir, enter second level water level distributor through water-distributing gap and pipeline again, in like manner, the distribution reservoir water level of second level water level distributor is low, ball-cock assembly is in open mode, water enters the guarantee case from water inlet through ball-cock assembly, the numerous capillary drip irrigation emitters that are on the same horizontal line with it obtain contour water level, begin to plant carries out drip irrigation, when second level water level distributor box water level arrived the limit for height waterline, buoyancy of water was closed ball-cock assembly, stop into water, water level also stops to rise, and avoids water to cause waste from coupled capillary drip irrigation emitter spill-over, simultaneously in the first order water level distributor, water level also rises gradually, during to the limit for height waterline, buoyancy is closed ball-cock assembly, stops into water, when cause water level to descend for the plant drip irrigation, ball-cock assembly is opened again once again, carries out the moisturizing operation, so repeatedly, just finished the automatic water supplement of capillary drip irrigation system, the automatic dripping irrigation function.

According to law of connected vessels, the capillary drip irrigation system can constantly be expanded in the horizontal direction, and introduce the water level distributor it can constantly be expanded at gravity direction, and namely the scale of capillary drip irrigation system is changeable, also can adapt to various landform.

The narrow gap of little water delivery device is extremely limited to the capillary rise height of water, have only about several centimetres, so the employed ball-cock assembly of water level control box must accurately respond SEA LEVEL VARIATION, but the capillary drip irrigation system is if need extensive expansion, will be subjected to the influence of ball-cock assembly moisturizing speed again, obviously, Chang Gui ball-cock assembly is difficult to satisfy simultaneously above 2 requirements.

For this reason, propose a kind of ball-cock assembly again, Fig. 5 is the structural representation of ball-cock assembly when being in open mode, it is by basic bar (26), driving shaft (27), driven shaft (28), driving lever (29), follower lever (30), connecting rod (31), fly rod (32), ball float (33), adjusting nut (34), rocking bar (35), valve rod (36), guiding mechanism (37), spool (38), valve body (39) is formed.

At basic bar two fixed axis are set, be respectively driving shaft and driven shaft, driving lever can rotate around driving shaft, follower lever can rotate around driven shaft, link to each other with connecting rod link between follower lever and the driving lever, at driving lever and connecting rod link connecting place fly rod of hinge again, the fly rod other end is provided with ball float, ball float is fixed on the fly rod with adjusting nut, at connecting rod and follower lever hinge connecting place rocking bar of hinge more then, valve rod then is connected through the hinge at the other end of rocking bar, and can be along the guiding mechanism moving linearly, and the other end of valve rod then is fixed together with spool.

The course of work of ball-cock assembly is as follows: when water level rises, ball float is subjected to upwards operation of buoyancy, driving driving lever rotates around the driving shaft clockwise direction, connecting rod will drive follower lever and rotate around the driven shaft clockwise direction, thereby promote rocking bar to left movement, promote valve rod again along the guider moving linearly, make spool press to water inlet gradually, valve-off, water level stop to rise, because basic bar, driving lever, connecting rod, follower lever has been formed quadric chain, inherent characteristic according to quadric chain, when water level rises when making valve closing, driving lever and connecting rod in line, quadric chain becomes stable triangular structure by unsettled quadrilateral structure, Fig. 6 is the structural representation of ball-cock assembly when being in closed condition, no matter apply great moment from spool this moment, and quadric chain is moved, because this moment, line of action of force passed through driving shaft just, can not form moment at driving shaft, this just makes ball-cock assembly obtain to close reliably sealing effectiveness; And when water level descends, because the decline of ball float buoyancy, under the gravity and the pressure action of water inlet to spool of ball float and fly rod, quadric chain then is easy to be transformed into unsettled quadrilateral structure from stable triangular structure, only needs very little moment just can open valve and carries out the moisturizing operation, simultaneously, compare with traditional long-armed type ball-cock assembly, because this ball-cock assembly is when closing, transmission mechanism is the effect of moment by compression mainly, the elastic deformation amount is very little, so more can accurately respond SEA LEVEL VARIATION.

In addition, because in this capillary drip irrigation system, water-head is very little between higher level's water level distributor and the subordinate's water level distributor, the pressure that spool bears is also smaller, can do the spool area more much biggerly than the water inlet of general aperture ball-cock assembly, effectively improve moisturizing speed, so just provide advantage for the extensive expansion of capillary drip irrigation system.

At natural world, water is subjected to the time, space, the influence of geographical conditions, the wish with people does not exist, and the olighydria phase can be caused drought, but can cause big flood during water flooding, therefore, rational utilization of water resources how, the deposit water resource becomes the major issue of people's water.

For this reason, a kind of water conservancy method is proposed, Fig. 7 is water conservancy type capillary drip irrigation system structural representation, the other filter screen (41) that arranges in the higher river course of physical features (40), filtered water is caused static pressure pond (43) by pipeline through one or more hydraulic water level control valves (42), down draw one section static tube (44) in the static pressure pond, the carrier pipe (45) that connects horizontal laying in the static tube bottom, carrier pipe lays afield, one section sand dispersing tube (49) is down drawn in the place that physical features is lower in the distance, let out husky valve (50) terminal setting of sand dispersing tube, let out husky valve below correspondence deposition pond on a hill (51) is set, approach terminal position at carrier pipe, upwards draw one section water-supply-pipe (46), at the water-supply-pipe end delivery valve (47) is set, the horizontal level of delivery valve is lower than the static pressure pond, the delivery valve correspondence position is provided with retaining pond on a hill (48), the less feed pipe of caliber (52) is upwards drawn in optional position at the carrier pipe of horizontal laying, non-return valve (53) continues upwards to cause the capillary drip irrigation system of being made up of water level distributor box (23) and capillary drip irrigation emitter (24), for the capillary drip irrigation system provides the water source, the first order water level distributor of capillary drip irrigation system and the horizontal level of capillary drip irrigation emitter are lower than delivery valve, obviously, can numerous feed pipe be set at carrier pipe and provide the water source for numerous capillary drip irrigation system.

This water conservancy method has three kinds of mode of operations:

In dry season, the discharge of river is very little, close and let out husky valve and delivery valve, water in the river course enters the static pressure pond through filter screen and hydraulic water level control valve, under the static pressure state, only carry out water-saving irrigation through non-return valve supply capillary drip irrigation system, at this moment, because water velocity is extremely slow in the carrier pipe of horizontal laying, the sandy soil in the current will deposit in carrier pipe, and can not enter the capillary drip irrigation system, reduced the maintenance of capillary drip irrigation system, simultaneously owing to being provided with hydraulic water level control valve, when the static pressure pool water level is full, hydraulic water level control valve will be closed, stop into water, hydraulic water level control valve will be opened moisturizing when the static pressure pool water level descends, and system is low-keyed to the diversion in river course, what what get with all finish automatically, reduced the influence to river channel ecology.

In the wet season, the discharge of river increases, and closes and lets out husky valve, opens delivery valve, and the water in the river course enters the static pressure pond through filter screen and hydraulic water level control valve, under the static pressure state, and through carrier pipe, water-supply-pipe; Delivery valve supplies water for the retaining pond on a hill, for industrial agricultural production water facilitates, simultaneously, because the horizontal level of delivery valve is higher than the capillary drip irrigation system, so the work of capillary drip irrigation system is also unaffected, in this course, though the water velocity in the carrier pipe increases to some extent, but still be lower than the long-pending toggle speed of becoming silted up of pipeline, so the sandy soil in the water will continue to deposit in carrier pipe.

In flood period, the discharge of river increases suddenly, flood will be considerably beyond the normal drainability in river course, productive life to the downstream causes very big harm, in this case, flood discharge becomes top priority, at first close delivery valve this moment, open then and let out husky valve, let out under the double action of the negative pressure that causes under the current in the pressure of the water water in static tube in the carrier pipe and the sand dispersing tube, high velocity stream is to the deposition pond on a hill, simultaneously, non-return valve is owing to upper pressure is closed greater than bottom pressure, static tube and carrier pipe, sand dispersing tube forms a closed conduct, and because the normal throw of static tube and sand dispersing tube, equal for the static pressure pond a powerful suction pump to be installed, the static pressure pool water level descends and makes the flood in river course add to the static pressure pond through hydraulic water level control valve again, realize that rapidly flood being carried out the strange land shifts, thereby reduced the flood passage pressure in downstream, river course, in this course, because water velocity is far longer than the toggle speed that the pipeline inner product is become silted up in the carrier pipe, so when shifting flood, the sandy soil of alluvial also have been transferred to the deposition pond on a hill in the pipeline, solve the long-pending problem of becoming silted up of pipeline effectively.

Obviously, the identical river constructions of many covers can be set in same river course, more flood can be deflected from the river course and hold and be equipped with, development and use make flood turn bane into boon more efficiently.

In addition, the deposition pond on a hill can the step construction, enlarges the flood storage ability, simultaneously can develop wetland economy, because the deposition of mud, the deposition pond on a hill is after using for a long time, will become the good farmland that is fit to farming, as long as carrier pipe is prolonged, and with sand dispersing tube with let out husky valve and be arranged on the farther place, can open up new deposition pond on a hill, a whole set of river construction is convenient flexibly, has gathered water-saving irrigation, water resource is carried, and water resource is held and is equipped with, and flood is dredged, pipe dredging, landform are reinvented multinomial function.

Optimum implementation

Select the specifications of quality, the float flat glass that chemical property is stable is made little water delivery device, and in the process of making little water delivery device, control the capillary trace, move trace, the thickness of gravity trace and number, the speed of dropping water of little water delivery device be made into 3-4 drip/minute, each drip irrigation mouth day output is about 1000ml, and it is required to be more suitable for the plant growth, and adopts uninterrupted drip irrigation system, need not manual intervention, more save artificial input.

Beneficial effect

In the capillary drip irrigation emitter, because the passage that water moves outside the past container in container is narrow gap rather than micropore, making the power of water motion is that narrow gap is to capillary force rather than the pressure of water, and capillary force only works to water, then inoperative to solids such as sandy soil, adopt uninterrupted drip irrigation system simultaneously, make salts substances constantly be avoided the salt accumulation by dilution, be equipped with again and make little water delivery device be in the working environment isolated with light, stop microbial growth, so just make the capillary drip irrigation emitter avoid sandy soil, salt and microorganism are stopped up, reduce system maintenance and obtain overlength service life, reduce a year use cost.

Since the capillary drip irrigation emitter to drip speed extremely slow, water will be distributed near the root system of plant no rainwash with soil capillary suspended water form, evaporation discharge is minimum, is conducive to the efficient utilization of water resource, more water-saving, because irrigation volume is minimum, can avoid salt to come the secondary salinization of soil in caused soil with water simultaneously.

Adopt uninterrupted drip irrigation system, need not manual intervention, more less manpower more meets the plant growth simultaneously to this growth rhythm of uninterrupted demand of water, more is conducive to improve the soil output.

Adopt uninterrupted drip irrigation system, at plant transpiration amount few night, to more deep soil diffusion, grow to the depths by the guiding root system under gravity and capillary force effect for water, avoids wind-force to dial root harm.

The overall process of water running all is by intrinsic naturally strength, need not energy resource consumption, and energy-saving and environmental protecting are not high to water quality requirement, need not secondary filter equipment, more save operating cost, and in office where the district all can be used.

Principle is simple and clear, and is simple and reliable for structure, and the user need not Special Training and can skillfully install and use equipment.

Because in the capillary drip irrigation system, contacting by law of connected vessels between water level distributor and the capillary drip irrigation emitter finished, there is not the pressure decay restriction of pressure type drip irrigation system, the size expansion aspect has more advantage, simultaneously since communicating pipe the required hydraulic pressure that bears atomic little, can use thinner pipeline and pipe fitting, more economical with materials and construction cost more easily.

The capillary drip irrigation system adapts to various environmental conditions, overlong service life, and reliability is higher, to desertization, desertification, the ecological recovery of Rocky Desertification Region has more practical significance.

Because uninterrupted drip irrigation system need not manual intervention, is particularly suitable for the city roof greening, with the fruit tree of perennation, shrub substitutes traditional thermal insulation layer, environmental protection again elegant in appearance can reduce building energy consumption for cooling in summer, effectively solves the not enough and air cleaning problem in urban green space.

Can flexible supporting river construction, cooperate hydraulic condition of river to change, realize water-saving irrigation, water resource is carried, water resource is held and is equipped with, and flood is dredged, pipe dredging, landform is reinvented multinomial function, water resource is carried out time and space regulate, and is conducive to properly settling of upstream and downstream area water rights benefit contradiction.

As adopt float flat glass to make little water delivery device, use aluminium alloy to make the water container of capillary drip irrigation emitter, can make long a century that exceedes of life-span of capillary drip irrigation emitter, ensure that being irrigated plant finishes at least one life cycle, guarantee investment return and ecological income, because glass and aluminium alloy are recyclable Recycling material, significantly reduced environmental pollution simultaneously.
