Description
Technical field
The present invention is a kind of irrigation and water conservancy water-saving irrigation system with real time monitoring function, belongs to water conservancy water-saving irrigation system
Command domain.
Background technology
China is one of country for seriously lacking freshwater resources in the world, and irrigation and water conservancy engineering irrigation is to storing rainwater, protecting
Barrier and adjust agricultural production water, that agricultural development and increasing peasant income is promoted to play the role of is great, therefore, carry out irrigation and water conservancy filling
Irrigating engineering just seems most important, and water-saving irrigation technique is directly related to the agricultural production of common people, is also passed through with China rural area
The development of Ji and agricultural production is closely related.It improves irrigation and water conservancy water-saving irrigation technique, complete agricultural production demand as China
The first-elected problem of further developing agricultural production.In ruck in the eyes, farmland water-saving irrigation is probably exactly " how with more
Few water supports more crops ", meet oneself life requirement, and in fact, this, which is not merely one, uses water
Wisdom live, but to improve utilization rate of the crop to precipitation and the soil water, to reduce agriculture by diversified technological means
Possible water loss and water waste during field is irrigated, water-saving irrigation technique are broadly divided into irrigation method, water-conveying method, filling
Irrigate the four big classification such as system and field ancillary method；Irrigation method：Irrigation method, that is, field decreasing water distribution method is how to have sent
Irrigation water to the edge of a field is uniformly distributed in crop root mobile layer, is which kind of approach to enter root system by live by irrigation water
Dynamic layer, irrigation method can be divided into surface irrigation, sprinkling irrigation, slight irrigation and sub-irrigation；Surface irrigation：Water is to enter field from ground surface
And rely on power and capillarity infiltration soil for support, so referred to as gravity douche, surface irrigation is ancient traditional side of pouring water
Method, generally it be as compare whether water-saving basic point, but surface irrigation technology is also evolving constantly improve, institute
With also there are many methods more water-saving than traditional ground irrigation technique recently；Sprinkling irrigation：Pressure water is sent to filling using special equipment
The advantages of irrigating location, and be ejected into and dissipate into tiny water droplet in the air, irrigated as natural rainfall, being protruded is the adaptation to landform
Power is strong, and mechanization degree is high, pours water uniformly, water efficiency of irrigation is high, is particularly suitable for the strong soil of water penetration, and be adjusted
Air humidity and temperature, but capital expenditure is high, and affected by wind big；Slight irrigation：Irrigation system is formed using micro-irrigation equipment, it will
The water for having pressure is transported to field, and the one kind for moistening soil near crop root with small flow by douche is poured water skill
Art is mainly characterized by only infiltrating soil around crop when irrigating, far from crop root in the ranks or between soil conservation do
Dry, general flow of irrigating is all more much smaller than irrigating comprehensively, therefore also known as micro irrigation, abbreviation slight irrigation, including infiltrating irrigation, drop
Filling, gushes filling and irrigation on plastic membrance etc. at microspray irrigation.Major advantage is：It pours water uniformly, saves energy, flow of pouring water is small, to soil and landform
Adaptive faculty it is strong, can improve the yield of crop, increase salt resistance ability；Convenient for active control, hence it is evident that save labour.It is relatively more suitable for
Irrigate wide row crop, fruit tree, grape, melon and fruit etc..
Prior art discloses application No. is：A kind of irrigation equipment and system of CN201220309115.5, specially one
Kind good filtration effect, it is easy to control, it can irrigate in time, be suitable for the irrigation and water conservancy water-saving irrigation system of Yellow River basin.It is wrapped
Include sequentially connected water fetching device, water treatment facilities and irrigation device；The water fetching device includes water pump (1) and non-return valve
(2)；The water treatment facilities includes detaching the primary treatment device of sandstone and the secondary mistake for removing organic impurities
Filter device；Primary treatment device uses centrifugal sandstone separator (3), and water inlet is connected by non-return valve (2) and water pump (1)
It connects；Secondary filter assembly uses sandrock filter (4), and water outlet connects irrigation device by water main (5)；Sandstone separator
(3) water outlet is connected with the water inlet of sandrock filter (4) by the irrigation main valve of setting.Advantage is, if
Meter is reasonable, and filtration treatment quickness and high efficiency, easy to operate, service life is long, at low cost.The water saving measures that the prior art is taken are more
Comprehensively, it is not higher to the invalid evaporation of soil moisture during being irrigated, and easily moisten it while irrigating
The soil in his region causes weed growth too fast, interferes the production of crops, and monitoring function is incomplete, can not be to farmland
In indices monitored in real time.
