Abstract
The present invention relates to an automatic irrigation switch, in the concrete, it is an automatic irrigation switch capable of automatically controlling water-conveying flexible pipe opening and closing according to the change of soil humidity. It is formed from a hard supporting frame and a high humidity absorbency plastic swelling and shrinking pipe. Said invention can be extensively used in the places of garden, greenhouse, field and park, etc.
Description
Technical field
The present invention relates to a kind of irrigation switch, particularly a kind of automatic irrigating switch by soil moisture control.
Background technology
Automatic irrigation system is made up of devices such as humidity sensor, microcomputer control, magnetic valves usually, needs the energy work of power supply.Complex apparatus and high its application of price limit.
I am at Chinese invention patent (application number: 200610000026.1) proposed a kind of automatic irrigating switch, be made of rigid support, breathing body and set screw.Utilize wood materials chance hygral expansion and dry principle of shrinking that the software water-supply-pipe is pressed and block up and release out, thereby water flows in the control hydraulic pipeline.The breathing body is made by natural material, corrosion resistant not, about about 2 years of life-span.The natural material heterogencity causes the difference of breathing amount between the breathing body, needs the difference of set screw compensation breathing amount, complex structure.
Summary of the invention
The objective of the invention is to propose a kind of corrosion-resistant, the life-span long, the automatic irrigating switch of not consumed power simple in structure.
Technical scheme of the present invention is: a kind of automatic irrigating switch, constitute by rigid support, breathing body, and the breathing body is installed in the rigid support, during work the software water-supply-pipe is inserted in the rigid support.The breathing body is made by high hygroscopic plastic.
Described hard support is that plastics, pottery, glass or metal are made.
Described breathing body is that high hygroscopic plastic is made, and is specially the doping polypyrrole, high moisture absorption nylon, and strengthen moisture-absorption modified plastics.
Principle of the present invention is to utilize high hygroscopic plastic, the moisture absorption volumetric expansion, the dehydration volume contraction, the breathing process is reversible, comes the variation of perception soil moisture, and by rigid supporting structure and breathing body folder is controlled the software water-supply-pipe, the expansion of breathing body and contraction cause the pressure of delivery hose to block up and release out, reach the automatic switch control to irrigating, according to the different breathing rates of each high hygroscopic plastic, the length of design breathing body makes its swell increment can reach abundant pressure and blocks the software water-supply-pipe and get final product.
1, the present invention adopt synthetic high hygroscopic plastic replacing wood or bamboo wood as the sensing element of soil moisture and the driving element of irrigating control as the breathing body, do not need electric power just can control irrigation automatically, synthetic high hygroscopic plastic anti-corrosion property is strong, and the life-span can reach more than 20 years in soil.Synthetic high hygroscopic plastic is homogeneity materials as industrial products, and the breathing amount that the breathing body that is processed into is every is consistent, can save set screw, simplifies the structure.
2, the present invention is applicable to garden, greenhouse, field, gardens, is specially adapted to build the irrigation of body greening, the automatic irrigation of alternative common electric power control.
Description of drawings
Accompanying drawing is the schematic diagram of automatic irrigating switch of the present invention.
Embodiment
Below in conjunction with drawings and Examples the present invention is further described.
As shown in the figure, this automatic irrigating switch is made of rigid support 1, breathing body 2.During work the software water-supply-pipe is inserted in the rigid support of automatic irrigating switch, be held between the interior upper surface of breathing body upper surface and rigid support.
Rigid support is made with known injection moulding process by Acrylite, and the breathing body adopts aramid fiber 14 to make, and the software water-supply-pipe is the PE pipe.
The PE flexible pipe that has turn-offed the water source will be inserted earlier in the automatic irrigating switch, make the mouth of pipe be the irrigation radius to the length of switch room, automatic irrigating switch is put into water, make the abundant imbibition of breathing body, reach maximum swelling and press and block the PE delivery hose, at this moment open the water source of PE delivery hose, the anhydrous outflow of effluent pipe mouth.Automatic irrigating switch is inserted in the soil, closely contact with the breathing body for soil, if at this moment in the soil moisture insufficient, moisture is inhaled in the soil in the breathing body, the dehydration of breathing body is shunk, be retracted to a certain degree, the breathing body contract power and pressure under the PE delivery hose release out, water flows out irrigated soil, when ground moistening arrives the breathing body, the breathing body begins moisture absorption, and moisture is imported into the breathing body again and makes it to expand, and irrigation stops.Along with losing of soil moisture, soil is when moisture is insufficient once more, and automatic irrigating switch is opened irrigation again, carries out so repeatedly, reaches irrigated by the automatic control of soil moisture control.
Claims (3)
1. an automatic irrigating switch is characterized in that, is made of rigid support (1), high hygroscopic plastic breathing body (2), and the breathing body is installed in the rigid support.
2. automatic irrigating switch according to claim 1 is characterized in that, described hard support is made by plastics, pottery, glass or metal.
3. automatic irrigating switch according to claim 1 is characterized in that, described breathing body is that doping polypyrrole, high moisture absorption nylon and moisture absorption enhancing modified plastics are made.
