Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
As shown in Figure 1, 2, the Negative pressure irrigation automatic regulating system of energy-conserving and environment-protective of the present utility model, including water tank 10, perseverance
Determine water level controller 1, inlet channel 2, pressure-measuring pipe 3, vitrified-clay pipe 4, outlet conduit 12, fleece 7, circulating water pool 11；Potter's clay
Pipe 4 is embedded in soil, the peak level of water tank 10 less than vitrified-clay pipe 4 position, one end of vitrified-clay pipe 4 by inlet channel 2 with
Water tank 10 is connected, and pressure-measuring pipe 3 is provided with inlet channel 2, and constant water level controller 1 is connected with the bottom of water tank 10, controls water
The water surface of case is in constant elevation, and the other end of vitrified-clay pipe 4 is connected to circulating water pool 11, vitrified-clay pipe by outlet conduit 12
4 outside is surrounded by fleece 7.
Valve 5 and the water pump 6 for draining air in pipeline are additionally provided with outlet conduit 12.
The constant water level controller 1 includes the water supply container for sealing, the water filling port 8 positioned at container top and positioned at container
The air inlet 9 of bottom, height and the liquid level of water tank 10 of air inlet 9 keep same elevation.
Specifically, the Main Function of constant water level controller 1 can be the water surface at control system water source in constant
Elevation, it is ensured that the certain water source elevation needed for negative pressure.The Main Function of inlet channel 2 is that guiding current pass through vitrified-clay pipe.Pressure-measuring pipe 3
Main Function can be the situation of change for observing hydraulic pressure in pipeline at any time, and can detect whether water adding system is normally transported
Turn.Vitrified-clay pipe 4 (Ceramic, USA) has tubular character, and itself can possess permeable air-locked as a part for pipeline
Performance, and using soil matrix will definitely water be delivered directly in soil.This douche can not only be irrigated, and can also be controlled
Soil moisture content processed, makes the soil moisture content moment be maintained at the numerical value of optimum plant growth, realizes auto-control, saves water and energy
Effect.The Main Function of valve 5 is control outlet conduit.The Main Function of water pump 6 is to drain the air in pipeline.Test card
Under bright long-term operating, due to there is micro-bubble in natural water, potter's clay inside pipe wall is caused to tire out collection air so that efficiency of pouring water drops
It is low, so needing periodically exhaust.The Main Function of fleece 7 is so that vitrified-clay pipe douche contacts more good with soil, solution
The situation that certainly water-supply-pipe is blocked by soil little particle.
Below, the laboratory installation for designing according to the technical solution of the utility model, tests of the present utility model using effect
Fruit data, constant water level controller adopts geneva bottle, and concrete grammar is as follows：
1 test objective
Probing into the utility model automatic regulating system can actually reach target.

Length and width 30cm × 30cm, lucite one, the case of soil of high 20cm；One, little water tank；Lucite tube is some；Three
It is logical one；The vitrified-clay pipe of a diameter of 1cm；Native case, unit weight 1.68g/cm are inserted in wind desiceted soil layering3, saturated aqueous rate 22.15%
(mass percent)；One, little water pump；
3 test methods
First by geneva bottle installation, need to ensure that geneva bottle is working properly, good seal.Water in water tank is filled into
With one horizontal plane of geneva bottle air inlet.Fleece is wound around around vitrified-clay pipe.Connection pressure-measuring pipe, vitrified-clay pipe, valve
With water pump, test device air-tightness.The native case of adjustment and pressure-measuring pipe position so that water surface site within pressure-measuring pipe scale range,
It is easy to reading.Soil is inserted in layering.Open valve, starts water pump, after the air in aqueduct is all drained, shutoff valve
Door.Observe that liquid level is consistent with the water tank water surface in pressure-measuring pipe, and record reading.The change of the water surface in by observing geneva bottle
Change can observe the change of irrigation quantity.Negative pressure value in vitrified-clay pipe can be drawn by the change of liquid level in pressure-measuring pipe, it is also possible to
Detect system whether in normal condition.Periodically turn on valve, open water pump will manage in the gas discharge gathered, the water of discharge
Can recycle, saving water resource.
Installation system in manner just described is adopted, vitrified-clay pipe is apart from water source water surface 14cm.It is daily to survey soil moisture content, soil twice
The change of earth temperature, electrical conductivity and the geneva bottle water yield.
4 experimental results
4.1 wetted front situations of change
As shown in figure 3, wetted front change over time becomes larger, and wetted front change is uniform, illustrates to irrigate system
System is poured water uniform.
4.2 soil moisture content situations of change
As shown in figure 4, soil moisture content gradually increases by vitrified-clay pipe, 0.2cm is finally maintained at3/cm3Left and right, illustrates to fill
Water system can be with moisture content in auto-control soil.
4.3 irrigation quantity situations of change
As shown in figure 5, irrigation quantity linearly changes with the time, coefficient correlation is sufficiently close to 1.Explanation system can be realized bearing
Pressure is irrigated, and irrigation quantity is visibly homogeneous.
5 conclusion (of pressure testing)s
Test proves that system of the present utility model can be realized irrigating purpose, and according to wetted front change and irrigation quantity
Change can show that the system irrigation range is uniform.Can be learnt according to the change of moisture content can realize that what is irrigated self adjusts
Control.Exterior power is not needed in practice, can be had using this kind of vitrified-clay pipe Negative pressure irrigation system under certain suction head
Effect solves the problems, such as many other irrigation techniques.
Vitrified-clay pipe of the present utility model is in itself a part for pipeline and in its surface plus last layer fiber, will not be gone out
The situation of existing hollow billet blocking, and under the water-feed of tubular structure, irrigates that moisture is visibly homogeneous to be goed deep in soil, using work
Thing absorbs.Sprinkling irrigation is limited to weather condition, and wind is big and evaporation major region is difficult to adopt.But then have by the way of underground is penetrated into
What is imitated solves this problem.On the other hand, this kind of vitrified-clay pipe Negative pressure irrigation system can also be realized to irrigation quantity size, soil
The auto-control of moisture content, can cause soil moisture content to remain at optimum numerical value needed for plant growth, using front
Scape is very wide.
Embodiment described above is merely to illustrate technological thought of the present utility model and feature, its object is to make ability
Technical staff in domain is it will be appreciated that content of the present utility model and implement according to this, it is impossible to only limit this practicality with the present embodiment
New the scope of the claims, i.e., equal change or modification that the spirit disclosed in all the utility model is made still fall new in this practicality
In the scope of the claims of type.
