Accompanying drawing explanation
Fig. 1 is this utility model system construction drawing.
Detailed description of the invention
Below in conjunction with detailed description of the invention, this utility model is described in detail.
Infiltrating irrigation system under the drought and water-scarce area railway sand prevention reproducing area that this utility model relates to, includes water pump assembly 1, stem filter plant 2, hydraulic pipeline 3, irrigation control system 4 and douche 5, is separately provided with irrigation control room.
Water pump assembly 1 is made up of the water pump in being arranged on water supply well or in clear water reserviors and the startup cabinet being arranged on irrigation control indoor.
It is indoor that stem filter plant 2 is installed on irrigation control, including stem intake and exhaust relief valve, sandstone separator, automatic backwash sand filter, fertilizer applicator, auto-flushing well strainer, auto-flushing disc-type filter, effusion meter and non-return valve.
Hydraulic pipeline 3 uses the nontoxic rigid PVC plastic pipeline of U-PVC and pipe fitting, and be laid in underground, irrigated area, is divided into main, arm and sparge pipe.
Irrigation control system 4 is by being arranged on irrigation control indoor irrigation controller, power amplification case and the laying installation power transmission line in irrigation district and electromagnetic valve forms.
Douche 5 is the end-equipment of sub-irrigation system, and be laid in underground, irrigated area, is connected with the sparge pipe bleeder in hydraulic pipeline 3 and lays along vegetational zone, uses the 10~30cm turbulent pressure compensating drip irrigation belts laid below earth's surface, forest belt.Drip irrigation zone is manufactured with douche one-shot forming by hollow billet, and douche is integrated into a whole well with hollow billet, and the inside and outside wall of outlet is smooth, and drip irrigation zone is as common hollow billet, and installation and maintenance are very convenient.Owing to drip irrigation zone is embedded in below earth's surface, overcome ground hollow billet the most aging and by problems such as stream destructions under solar radiation effect, and decrease the invalid evaporation of irrigation water.Douche has turbulent pressure and compensates function, and irrigation uniformity is high, requires low to slight irrigation water transfer pipe network pressure harmony, it is possible to adapt to various rugged landform, and the maximum allowable discrepancy in elevation reaches 6m.Douche performance basic demand is: operating pressure is 5~25m heads, and crossing water flow passage aperture is 0.3~2.5mm, and outflow is 1~about 4L/h.
It is provided with chemical fertilizer (pesticide) decanting point between water pump assembly 1 and stem filter plant 2, non-return valve is installed, to prevent solution (pesticide) from recharging and polluted source between decanting point and water source.Relief valve and automatic inlet and outlet valve it is provided with on hydraulic pipeline 3;Relief valve is to prevent owing to arm valve is not opened, and constantly the pressurize high pressure that causes pipe network of water pump destroys;Automatically inlet and outlet valve is the gas in order to get rid of in pipe network, or supplements air in pipe network when termination of pumping, to there is negative pressure in preventing pipe.
Fertilizer applicator selects differential pressure type fertilizer spreading tank, Wen Qiulishi infusion appliance or fertilizer injection pump.Notably: the decanting point of chemical fertilizer (pesticide) have to be placed between water source and filter, make solution enter back into irrigation conduit after first passing through filter, make undissolved chemical fertilizer and other impurity be disposed of, in order to avoid blocking pipeline and douche;After fertilising (pesticide), it is necessary to utilize clear water all to rinse well remaining in intrasystem solution (pesticide), prevent equipment to be corroded;At chemical fertilizer (pesticide) between decanting point and water source, it is necessary to non-return valve is installed, to prevent solution (pesticide) from recharging and polluted source.
This utility model uses sub-irrigation system to irrigate, and utilizes the pipelines at different levels in drip irrigation system that water is delivered to douche, after douche will have the current energy dissipating of pressure, infiltrates sand prevention plant roots district with water droplet, and growing for plant normal growth provides nutrient water.Before implementing infiltrating irrigation engineering, it is necessary to water source used is carried out water quality test, grasps water quality condition comprehensively, and according to the douche kind selected by infiltrating irrigation system and performance of anti-blockage, reasonable selection cleaning equipment and facility, to ensure that irrigation system is properly functioning, improve quality of pouring water.After water pump assembly 1 diversion, after stem filter plant 2 filtration treatment, cause the hydraulic pipeline 3 of the underground, irrigated area that is laid in;Hydraulic pipeline 3 is divided into main, arm and sparge pipe, arm forms multi-region irrigating unit by group areas, irrigation water is grouped rotation flow through main to the arm of each irrigating unit, after after sparge pipe and turbulent pressure compensating drip irrigation belt pressure release energy dissipating drip irrigation in plant root.Rotation flow group is divided by following principle: 1) rotation flow group divide should meet plant need water requirement, plan irrigated area should be coordinated mutually with the water source water yield;2) area that each rotation flow group is controlled is the most equal, in order to make pump working stable, and improves the efficiency of dynamic power machine and water pump, reduces energy consumption;3) division of rotation flow group should be looked after sand-break as far as possible manage and protect so that it is work is convenient;4) in the infiltrating irrigation system automatically controlled, for reducing the flow of delivery main, rotation flow group preferably uses the mode of symmetrical flower arrangement.
In infiltrating irrigation system, drip irrigation zone is connected with final stage sparge pipe, douche above drip irrigation zone is end distribution apparatus, also it is the equipment that in infiltrating irrigation system, consumption is maximum, its installation cost and price have an important impact to the cost of infiltrating irrigation system, and the performance of douche directly influences infiltrating irrigation system and pours water the quality of quality, therefore, douche plays very important effect in infiltrating irrigation system, is the critical component of infiltrating irrigation system.
The laying of drip irrigation zone and water outlet inspection method:
Before laying drip irrigation zone, be according to forest belt planting requirement unwrapping wire.Foreign material are amassed in the earthwork removing sparge pipe place pipe trench section, according to drip irrigation zone paving location, punch on sparge pipe, install O-ring seal, joint, PE pipe, bypass, and are connected with bypass drip irrigation zone.Such as buildings such as irrigation control room and water supply well roads, then should be according to drip irrigation zone paving location and road width, pre-buried PE pipe and PVC pillar, at the two ends of PE pipe, it is respectively mounted bypass, then drip irrigation zone is connected with bypass.Drip irrigation zone should be embedded in below the earth's surface of trees side 10~30cm along landform.Drip irrigation zone must be smooth, without twisting, tiing a knot.
Check whether drip irrigation zone leaks with bypass junction, confirming without leaking tailing edge drip irrigation zone inspection drip irrigation zone water outlet situation to drip irrigation zone tail end.Open drip irrigation zone tail end draining 10~re-closed after 15 minutes.Drip irrigation zones as indivedual in same irrigating unit tail end not water outlet or water yield are less, then illustrate that certain position, this drip irrigation zone has breakage to leak, gives a discount or have foreign body in PE pipe, should give eliminating.In aforementioned manners, in units of rotation flow group, each drip irrigation zone is checked until all the normal water outlet in drip irrigation zone is irrigated.
Content of the present utility model is not limited to cited by embodiment, the conversion of any equivalence that technical solutions of the utility model are taked by those of ordinary skill in the art by reading this utility model description, is claim of the present utility model and is contained.
