Abstract
The utility model relates to an irrigation switch, specifically is an automatic irrigation switch which can automatically control switching of flexible water hose according to the changes of soil moisture, which comprises of a hard bracket(1), an expansion body(2) and regulation screws(3). The hard bracket is provided with the expansion body, and the regulation screws are screwed in the upper end of the hard bracket. When in use the flexible water hose is inserted in the hard bracket of the automatic irrigation switch and meanwhile is clamped between the lower end of the regulation screws and the upper end of the expansion body. The utility model has adaptive dynamic automatic switch function for the irrigation, automatic control ability without electricity, and no special decompression device needed in the water conveying pipeline. The utility model is easy to use, low price, and can be used for automatic control irrigation in courtyards, greenhouses, fields, gardens and greening plant of construction.
Description
Technical field
The utility model 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 price limit its application.
China's utility model patent file (application number: 200520127324.8) proposed a kind of automatic dripping irrigation and dripped arrow, form by rigid support, timber breathing sheet, rubber aqueduct, set screw, utilize wood materials to meet hygral expansion and dry principle of shrinking, the rubber aqueduct is pressed block up and open, thereby flowing of the water in the control piper, but this device is joined special decompressor outside needing, and can only work under 3 meters heads of low pressure, the pressure low discharge is little, and irrigated area is little.
Summary of the invention
The purpose of this utility model is the automatic irrigating switch that proposes a kind of not consumed power, humidity according to soil is controlled irrigation automatically, can directly connect with the water source, do not need the outer special decompressor of joining, can work under 40 meters head high pressure, the irrigation flow is big, has simple in structure, characteristics easy to use, that cost is low.
The technical solution of the utility model is: a kind of automatic irrigating switch, constitute by rigid support, breathing body and set screw, the breathing body is installed in the rigid support, rigid support upper end screws in set screw, with in the rigid support of software water-supply-pipe insertion automatic irrigating switch and simultaneously to being sandwiched between set screw lower end and the breathing body upper end, the structure of rigid support makes the breathing power of breathing body concentrate the stifled and release of pressure of the pressure that acts on the software water-supply-pipe during work.The breathing body is made by natural material, and the homogeneity of natural material is poor, causes the breathing amount difference between the breathing body, and set screw plays the effect of compensation breathing amount difference.
Described hard support is that timber, bamboo, plastics, pottery, glass or metal are made.
Described breathing body is that timber or bamboo are made.
Principle of the present utility model is to utilize timber or bamboo wood is tangential and moisture absorption breathing rate radially is big, the suction volumetric expansion, the dehydration volume contraction, the breathing process is reversible, and characteristic with the different breathing amount respective change of moisture content, come the variation of perception soil water amount, and control the deflection that inserts the software water-supply-pipe by the direction of rigid supporting structure control breathing power and reach and press stifled and release out, reach automatic switch control irrigating.
When soil moisture is abundant, closely the moisture in the breathing bulk absorption soil of contact soil expands, the software water-supply-pipe distortion of automatic irrigating switch is inserted in extruding, final compression is stopped up the water route and is stopped water outlet, when water evaporates in the soil and plant absorbing cause soil moisture inadequate, moisture in the breathing body also is absorbed in the soil and goes, its water content and soil moisture content descend synchronously, the breathing body shrinks, the pressure of constraint software water-supply-pipe reduces, under the pressure effect of water, the water outflow enters soil and supplies water to plant, the behavior of breathing body in dried wet environment is reversible, so this automatic irrigating switch can reach automatic control and irrigate according to the variation self adaptation dynamic adjustments switch of soil moisture.
The beneficial effects of the utility model are:
1. the utility model adopts timber or bamboo wood as the sensing element of soil moisture with irrigate the driving element of control, does not need electric power just can control automatically, and timber, bamboo wood cost are low.
2. the outer water-supply-pipe of software directly inserts automatic irrigating switch, plays the effect of aqueduct, has saved aqueduct structure, has avoided the water route interface between outer hydraulic pipeline and the automatic irrigating switch, like this problem of no distending under higher hydraulic pressure.The water delivery pressure that is suitable for, the irrigation flow is big, and the monomer irrigable area is big.
3. the utility model is applicable to the automatic control irrigation of garden, temperature, field, gardens and architecture greening plant, the automatic irrigation of alternative common electric power control.
Description of drawings
Accompanying drawing is the schematic diagram of the utility model automatic irrigating switch.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, this automatic irrigating switch is made of rigid support 1, breathing body 2 and set screw 3.The wood grain of rectangle breathing body is substantially parallel with the upper and lower end face, its lower end joins with hard support, leave the slit between two walls and the rigid support, during work the software water-supply-pipe is inserted in the rigid support of automatic irrigating switch, be held between breathing body upper end and the set screw lower end.Hard support 1 is made with known injection moulding process by polypropylene plastics among the figure.Set screw is the galvanized metal screw, and the breathing body adopts maple birch material to make rectangular block, and handles in order to long-term use with known water-based wood preservative.The software water-supply-pipe is common soft PE pipe.
The PE flexible pipe that has turn-offed the water source will be inserted earlier in the automatic irrigating switch, making the mouth of pipe is to irrigate radius to the length of switch room, switch is put into water, make maple birch breathing piece full of water, reach maximum swelling, the source capsule mouth of fetching boiling water there are flowing out, and hydraulic pressure is up to 40 meters heads about 25 meters heads, the spinning set screw does not flow out to water, automatic irrigating switch is inserted on the limit in the barrel of planting big tree, soil is closely contacted with maple birch piece, the mouth of pipe is positioned at a barrel center and is placed on Tu Mianshang, if at this moment moisture is insufficient in the soil, moisture is inhaled in the soil in the maple birch breathing piece, and the dehydration of breathing piece is shunk, and water flows out, increase along with soil moisture, moisture is conducted into again the breathing piece is expanded, and irrigation stops, along with soil evaporation and flowers absorb, soil is when moisture is insufficient once more, automatic irrigating switch is opened irrigation again, carries out so repeatedly, reaches irrigated by the automatic control of soil moisture control self adaptation by-pass cock.
Claims (3)
1. an automatic irrigating switch is characterized in that, is made of rigid support (1), breathing body (2), set screw (3); The breathing piece is installed in the rigid support, and rigid support upper end screws in set screw.
2. automatic irrigating switch according to claim 1 is characterized in that, described hard support is that timber, bamboo, plastics, pottery, glass or metal are made.
