Description
Technical field:
The utility model relates to subsurface irrigation, and particularly a kind of Negative Pressure Difference irrigation system and one can control the permanent Negative Pressure Difference irrigation rig that the water-feed of constant negative pressure head links.
Background technology:
It is a kind of irrigation new method of day the present invention that Negative Pressure Difference is irrigated, and it is antipriming pipe to be imbedded underground, relies on Guan Zhongshui and the Negative Pressure Difference that surrounding soil produces to carry out automatic irrigation, and whole system can be according to the automatic regulating pondage of situation that wets of doing of pipe surrounding soil; The suction penetrating irrigation system that Nanjing Soil Inst., Chinese Academy of Sciences is introduced oozes head, water-supply-pipe and cistern by suction to be formed, and cistern can be regulated water level, can fertilizer, water uses simultaneously.The shortcoming of regulating water level with cistern is, water level changes in the irrigation process, when soil moisture was in the bargain-hunting power section, the minor variations of suction can cause the significant nonlinear change of soil moisture, just was difficult to satisfy the suitable moisture content requirement of plant growth sometimes.The shortcoming that above-mentioned irrigation system exists is: can not be used for accurately measuring soil short time interval transpiration quantity, the purposes and the scope of application are less.
Summary of the invention:
The purpose of this utility model provides a kind of water that permanent suction head can be provided to soil automatically, makes soil remain at the constant humidity of suitable plant growth, and purposes is various, the permanent Negative Pressure Difference irrigation rig that the scope of application is wide.
Task of the present utility model is finished as follows, this permanent Negative Pressure Difference irrigation rig, it includes single or multiple suctions and oozes head, suction is oozed a top and is connected with a collection chamber by the sealing-plug sealing suitable for reading by tube connector, be communicated with water-supply-pipe on the sidewall of collection chamber, it is characterized in that: the water-supply-pipe other end inserts one of connection and is lower than the water-level regulator that head is oozed in suction, on the water-level regulator upper portion side wall overflow pipe is arranged, the spilling water graduated cylinder is placed in the overflow pipe below, be communicated with water pipe on the sidewall corresponding of water-level regulator top with a water-stop with the overflow pipe height, the water pipe other end upwards is communicated with the water-feed of a band metering scale, and water-feed top is equipped with the water-stop that is connected with pressurized water tubes.Be filled with in the water-level regulator and can stop solid particle and certain micro-organisms to enter filtering layer in the water-supply-pipe.A water-stop is housed on the water-supply-pipe, the drawing liquid implementation of port of a band water-stop is housed by three-way connection on the water-supply-pipe on water-stop top.The utlity model has following advantage: 1,, regulate the height of water level controller, the water of required permanent suction head can be provided to soil, crop is grown in the soil of suitable humidity as long as along with the variation of the suitable soil moisture of plant growth.2, by the precise metering of water-feed and spilling water graduated cylinder, can understand the transpiration quantity of different periods of soil at any time and discharge greater than soil moisture unnecessary in the controlled humidity, and by chemically examining the solutes content of discharging in this discharge water metering soil.3, can also take out the soil solution and give the infiltrating irrigation of soil water-filling by the drawing liquid implementation of port.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.Among the figure, 1. pressurized water tubes, 2. water-stop, 3. water-feed, 4. water pipe, 5. water-stop, 6. filtering layer, 7. water-level regulator, 8. spilling water measuring tank, 9. overflow pipe, 10. water-stop, 11. drawing liquid implementation of port, 12. water-stops, 13. water-supply-pipes, 14. collection chambers, 15. inhale and ooze head.
Embodiment:
Further describe embodiment in conjunction with above accompanying drawing.Permanent Negative Pressure Difference irrigation rig of the present utility model, include single or multiple suctions and ooze 15, suction is oozed 15 top and is communicated with a collection chamber 14 by pipe, in collection chamber is suitable for reading sealing-plug is arranged, be communicated with a reclinate water-supply-pipe 13 on the sidewall of collection chamber 14, be lower than suction at water-supply-pipe 13 other ends and ooze the permanent water level controller of head connection one cover, permanent water level controller is to make according to the law that the gas volume of certain mass and its pressure are inversely proportional to, after comprising pressurized water tubes 1 and add water, it can use the water-feed 3 of the band scale of water-stop 2 sealings, water-feed 3 bottoms are connected with water-level regulator by water pipe 4, water-supply-pipe 13 inserts certain depth in the water-level regulator 7, on water-level regulator 7 upper portion side wall overflow pipe 9 is arranged, a spilling water measuring tank 8 is placed in overflow pipe 9 belows, is communicated with the water pipe 4 with a water-stop 5 on the sidewall corresponding with the overflow pipe height of water-level regulator top.Ooze 15 in order to protect to inhale, the water-supply-pipe water-level regulator 7 in is filled with on every side and can stops solid particle and certain micro-organisms to enter filtering layer 6 in the water-supply-pipe.In order to enlarge the purposes of this device, a water-stop 10 is housed on water-supply-pipe, the drawing liquid implementation of port 11 of a band water-stop 12 is housed by three-way connection on water-stop 10 tops.During use, water-stop on the water pipe 45 cuts out, the water-stop 2 of pressurized water tubes 1 is opened toward water-feed 3 and is supplied water, water completely pass, back water-stop 2 is opened water-stop 5, height toward water-level regulator 7 water supply and adjustment water-level regulator 7 and overflow pipe 9, adjust to when as long as the water level of water-level regulator is reduced to less than one centimetre, the air of water-level regulator is by water pipe 4 past water-feed tonifying Qi, make when water level is elevated to less than one centimetre behind the water supplementary feed position adjuster of water-feed, overflow pipe 9 is like spilling water spilling water not again, replenish and stop, the water level of adjusting this system after the controller system adjustment finishes again oozes a relative relief of 15 with inhaling, and makes it equal the suction value that soil moisture need be controlled.Again with 10 sealings of the water-stop on the water-supply-pipe 13, open collection chamber 14 bleed the decompression and fill water after seal, drive water-stop 10 again, ready to balance a period of time, because of the crop water consumption, soil evaporation and dehydration, when soil suction is oozed head and is promptly inhaled the suction that oozes the head maintenance with the water level discrepancy in elevation of permanent water level controller system greater than suction, the water of water-level regulator 7 flows to inhale by water-supply-pipe 13 and oozes 15, and water-feed air inlet moisturizing is given water level adjuster 7 and water level depression, and drop-out value is a transpiration quantity.Ooze 15 suction that keep because of precipitation or washing salinity by irrigation soil suction less than suction, overflow pipe 9 can there are flowing out spilling water measuring tank 8, and it is measurable to flow out water, also can be used for analyzing its solute species and quantity.If want to extract the soil solution, connect soil solution draw-out device on drawing liquid implementation of port 11, to open water-stop 12 and close water-stop 10, decompression is bled.If the soil water is increased fast, water source tube can be connected on the drawing liquid implementation of port 11, close water-stop 10, open water-stop 12, or the water level of water level raising adjuster is equal to or higher than to inhale and oozes a burial place of 15, can realize not having pressing and irritate or infiltrating irrigation.
