Abstract
The soil suction irrigation system is composed of water-conveying pipeline whose one end is immersed in water source and water-infiltrating device which is made of water-permeable air-tight material, connected with the above-mentioned water-conveying pipeline and embedded in soil. Said invention has no need of power device, can save energy source and water source, is simple in irrigation system structure and convenient for construction.
Description
The present invention relates to a kind of soil irrigation system, particularly soil is inhaled fill system.
The irrigation system of soil is divided by the mode of movement of water has various ways, and self-flowing type is irrigated the power of weighing again and irrigated, and this irrigation distributes water resource on time and space all very rough, and water resource waste is serious.Other has a kind of is that pressure is irrigated, and present sprinkling irrigation, drip irrigation, infiltrating irrigation and micro irrigation technology just belong to this mode.Pressure is irrigated and is made water resource distribution spatially no longer be subjected to the constraint of gravity, and efficiency of water application increases.But pressure irrigates that the energy consumption still have the equipment cost height, to keep irrigation is big, the defective of complicated operation.
The objective of the invention is to need not power set in order to provide a kind of, soil simple in structure is inhaled fill system.
The object of the present invention is achieved like this, and a kind of soil irrigation system comprises water source, aqueduct and seepage controllor, aqueduct one termination water source, and seepage controllor is made by permeable air-locked material, and links to each other with aqueduct.
Described soil irrigation system, described permeable air-locked material are porous pottery, cellular glass, polypropylene hollow fiber membrane, nylon leaching film, the mixed fine filter membrane of acetic acid, polyvinylidene fluoride film, polyether sulfone micro-filtration membrane.
Described soil irrigation system, the end in aqueduct water receiving source is equipped with filter.
Described soil irrigation system, the filter core of its filter is made of permeable air-locked material.
Described soil irrigation system is equipped with the control water valve at the aqueduct water inlet.
Described soil irrigation system, described seepage controllor are the delivery pipe branch road.
Described soil irrigation system, described seepage controllor are the tube that two ends and aqueduct link.
Described soil irrigation system, described seepage controllor are that the infiltration sheet material is installed on the aqueduct wall.
Described soil irrigation system, described seepage controllor are tube, jar shape thing or the peviform thing that an end communicates with aqueduct.
The present invention compared with the prior art, the aqueduct of use is the relative system of sealing, field moisture content suction can be delivered to water inlet, finish the irrigation of water, need not power set, both energy savings effectively, make the irrigation system structure simpler again, it is more convenient to construct.As long as will produce suction to water because the water content of soil is lower than maximum field capacity, soil is dried more, suction is big more, when soil moisture content drops to the crop permanent wilting point, soil suction can be up to the height of meter water column more than 150, when field capacity hanged down to the initial wilting point of crop, soil suction was also at 0.6-63 meter water column height.Red soil for example, with estimation, the one mu of topsoil soils (by 150,000 kilograms) that is in water content and is the crop permanent wilting point can absorb more than 10 ton of water from 0.6 meter dark water surface makes soil moisture content reach field capacity, and this is a kind of huge energy.Simultaneously, the negative correlativing relation of soil moisture content and soil suction makes to inhale between filling ability and the soil moisture content and also forms negative correlativing relation, and this reaction type self-control effect makes soil moisture can keep certain equilibrium state, can realize the purpose of economizing on water again.
The invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the embodiment of the invention 1.
Fig. 2 is the structural representation of the embodiment of the invention 2.
With reference to accompanying drawing, number in the figure and object are: cistern 1, cistern top water inlet 2, cistern bottom water inlet 3, sand filter blanket 4, communicating pipe 5, air induction hose 6, feed cistern 7, filter 8, control water valve 9, water delivery trunk line 10, delivery pipe branch road 11, irrigator 12, cistern 13.
Embodiment 1: with reference to accompanying drawing 1, feed cistern can directly be a cistern 13, water inlet one end of water delivery trunk line 10 immerses in the water, and irrigator 12 is made of permeable air-locked material, and the interface position of aqueduct 10,11 is tightly connected by fluid sealant sealing or elastomer connector.Certainly, in the middle of irrigator 12 is placed into the soil, when the moisture in the soil because of the transpiration of evaporation, plant when reducing, soil can absorb water from inhale fill system, thereby suction is delivered to the into first end of water, and the first end of intaking immerses in the feed cistern, like this, just the suction that the water in the feed cistern produces by soil can be sent in the soil and go, realize that the self-priming of soil is irrigated.This embodiment is fairly simple, and construction makes things convenient for manyly comparatively speaking; But this mode is higher relatively to water quality requirement.
Embodiment 2: with reference to accompanying drawing 2, feed cistern can be made up of cistern 1 and adjustable feed cistern 7, cistern 1 is connected by communicating pipe 5 with adjustable feed cistern 7, in adjustable feed cistern 7, place an air induction hose 6, air induction hose 6 communicates with cistern 1, and an end of water delivery trunk line 10 stretches in the adjustable feed cistern 7.Water in the cistern 1 can flow to feed cistern 7 by communicating pipe 5, just stops into water when equal with the mouth of pipe of air induction hose 6 when feed cistern 7 waterborne is raised to; When soil suction reduces water in the feed cistern 7, also can keep the water in the feed cistern 7 totally to remain unchanged in this way, make the hydraulic pressure in the feed cistern keep constant.
Embodiment 3: with reference to accompanying drawing, promptly add a filter 8 on the water inlet of aqueduct 10, to guarantee the cleaning of the water quality in the aqueduct, prevent that impurity from entering pipeline and causing obstruction.
Embodiment 4: be the water content of control soil, can set up the humidity that a control water valve 9 is controlled soil at the water inlet of aqueduct.The suction that to be water valve produce in soil moisture content is opened during greater than certain value, makes the water inlet water inlet; When the suction of soil water-containing volume production dirt reduced because of the increase of soil moisture content, water valve cut out automatically.
Aqueduct and cistern interlink, and also can join with water supply pipe.Convenient for retaining, cistern can be designed to half semi-underground form on the ground, or links to each other with channel, domatic or peripheral water facilities such as initial detention groove and water lifting machinery.
The filter core of the used irrigator of the present invention can be made of permeable air-locked material.
The used irrigator of the present invention can be the perforated tubular thing that two ends are connected with aqueduct.
The used irrigator of the present invention can be permeable air-locked tablet of installing on the aqueduct wall.
The used irrigator of the present invention can be an end and communicates, can insert permeable air-locked tube in the soil, jar shape thing or peviform thing with aqueduct.
The used permeable air-locked material of the present invention can be cellular glass, polypropylene hollow fiber membrane, cellulose acetate film, polyvinylidene fluoride film.
The permeable airtight relativity that has of the present invention, as used porous ceramics hole aperture 2.8 microns the time, the gas leakage value is equivalent to 1 pressure about atmospheric pressure, negative pressure value this seepage controllor energy under the situation that is no more than 1 atmospheric pressure that can guarantee water adding system inside is permeable airtight, makes the water adding system operate as normal.
