Description
Technical field
The present invention relates to a kind of device, particularly nozzle-integrated sprinkling irrigation precipitation generator of artificially-simulated rainfall sprinkling irrigation.
Background technology
Artificially-simulated rainfall is not controlled by natural rainfall, and takes artificial means by equipment such as water system, control system, rainfall generator systems, completes simulated rainfall sprinkling irrigation process, satisfies the device of water use sector required water.The core technology of artificially-simulated rainfall is the rainfall generator.In recent years, develop both at home and abroad and permitted eurypalynous artificially-simulated rainfall device, be widely used in hydraulic engineering and the field scientific researches such as agriculture project, water and soil conservation.
Its rainfall simulator system is comprised of water system, dynamical system, control system, simulated rainfall machine substantially.The simulated rainfall machine is made of stand-alone vertical tube, extension, rainfall generator and tripod etc.Various rainfall simulation generators are divided into nozzle-type raindrop generator and needle tube type raindrop generator; Nozzle-type is from nozzle or spray orifice, water to be injected in the air, is subjected to the impact of air drag effect, and the broken raindrop that form different sizes of current drop to the earth's surface, and the raindrop of its generation vary, and are more similar to the raindrop of natural rainfall.Needle tube type is that current flow through numerous syringe needles or tubule forms raindrop.Because the raindrop that produce are too even, distributing with the raindrop of natural rainfall differs greatly and uses less.
The nozzle-type shower nozzle is divided into again lateral spray type, following spray: lateral spray type is exactly that current upwards spray after stream breaker blocks at an angle, is movement of falling object landing earth's surface after the maximum height, and the movement locus of water droplet roughly is parabolic.Great advantage is that water droplet is the movement of falling object, and the raindrop of single shower nozzle distribute relatively good, can change rainfall intensity by selecting different shower nozzle combinations and different nozzle diameter, adjustment water flow pressure.Under being that following spray adopts, the spray form produces rainfall, and characteristics are that water droplet has certain initial velocity when leaving rain controller.Mode according to controlling rainfall intensity can be divided into pivoted arm, rotating disc type and swing type.Pivoted arm is comprised of the turning arm that a plurality of shower nozzles much are installed, and can realize the control of rainfall intensity by the speed of adjusting the turning arm rotation.Rotating disc type and pivoted arm comparing class seemingly drop to the earth's surface but rainfall is opening part by rotating disc.Swing type is to control rainfall intensity by the frequency of adjusting the shower nozzle swing.
At present, although domestic and international various rainfall simulator can be simulated the natural rainfall process, every test index all meets code requirement, and its comparison in equipment is complicated, invariably takes multiplet, or combination or increasing optional equipment realizes the simulated rainfall process.Develop single shower head artificial simulating rainfall appts as 2003～2009 applicants, once develop four generation product: 1. single shower head artificial simulating rainfall appts (ZL03214113.0); 2. two regulating artificial analogue rain showers (ZL200620090015.2); 3. curve surface lateral throwing type raining spray nozzle (ZL200620090125.9); 4. single-nozzle oscillatory-type manual rainfall simulation generator (ZL200820012232.9).Realized replacing with the single spraying head target of many shower nozzles combine analog rainfall.The simulated rainfall process is adjustable, and the rainfall zone is fan-shaped, control area 〉=150m
2But simulated rainfall intensity is 30～200mm/h (being preferably lower than 50mm/h and practical application is suitable for the rainfall intensity of crops); The simulated rainfall raindrop diameter has embodied rainfall essence fully near the raindrop diameter of natural rainfall, and rainfall is even, there is no " hollow " phenomenon, and the performance luffing of simulated rainfall is less.Passed through CMA water-saving irrigation device quality testing center test, result meets the GBJ85-85 quality requirement.Although perfect through repeatedly transforming, under the constant prerequisite of retention, the design that simplifies the structure, but still need nearly 10 parts to assemble can't be referred to as simple in structurely, and performance is constant.
Show according to related data: China is one of water resource serious country in short supply in the world, and water resources ownership per capita is about 1/4 of world average level, the agricultural water resources insufficient total amount, and increment is limited.Use the rainwater efficient technique of rainwater utilization if national dry farming is ploughed, can make the precipitation utilization rate improve 5～10 percentage points, can increase and utilize precipitation 200～40,000,000,000 m
3Take full advantage of natural rainfall, greatly develop dry farming and water-saving irrigation, will become the Major Strategic approach that solves China's shortage of water resources.The key that solves the agriculture, rural areas and farmers problem is Development of Water-Saving Irrigation agricultural, industrialized agriculture.Therefore, develop simple in structurely, simple load and unload simple and easy sprinkling irrigation precipitation generator efficiently becomes one of important content that solves Development of Water-Saving Irrigation agricultural, industrialized agriculture.
