The water bag 2 of this device is arranged in tank 1, and its top has the surplus upwards bulged, for forming shutoff when bulging to tank 1; Water bag 2 is provided with water inlet and delivery port, and water inlet is preferably arranged on the side of top near water source of water bag 2, for passing into water source, being arranged on top and conveniently discharging the gas that may exist; Delivery port is preferably arranged on the bottom of water bag 2 draining side, for being discharged by the water in water bag 2.
Kickboard 3 is arranged in water bag 2, be injected in water bag 2 for being made water source by the buoyancy of self, because when irrigating, the water level of side, water source can raise, and kickboard 3 is floated and is floated among water bag 2 all the time, the top of kickboard 3 pairs of water bags 2 is formed and supports, and makes the water level in water bag 2 constantly be tending towards water level, ensure that the lasting inflow at water source.
The top of drainpipe 4 is connected to delivery port, and down, be erected at by the first supporting leg 41 is vertical the top waiting to irrigate field, the first supporting leg 41 can be four, is plugged in and waits to irrigate in field in the bottom of drainpipe 4; Float chamber 5 is arranged on the below of the bottom of drainpipe 4 by the second supporting leg 51, and the second supporting leg 51 can be four corresponding with the first supporting leg 41, and is connected with the first supporting leg 41, improves the integrated level of single unit system, convenient installation; Float chamber 5 is provided with open top and bottom opening, and the float chamber 5 of the present embodiment is open design, and the uncovered i.e. open top of float chamber 5, float 6 is plugged in float chamber 5, and float chamber 5, for being formed spacing to float 6, prevents float 6 from wafing.
The top of float 6 is provided with occluding body 61, occluding body 61 for forming shutoff with float 6 levitating to the bottom of drainpipe 4 in time irrigating field and reach and stop irrigation level, conical surface seal is preferably between the bottom of occluding body 61 and drainpipe 4, for the float 6 having lasting buoyancy, taper-face contact can make to have lasting relative pressure between itself and the bottom of drainpipe 4, and sealing effectiveness is better.
As for the setting stopping irrigation level height, well imagining, is determined by the antenna height of the bottom of drainpipe 4.Concrete stopping irrigation level can being determined according to actual conditions, as the irrigation to Rice Seedlings, stopping irrigation level being arranged on 3 centimetres high, maturing stage is then arranged on 8 cm, the suitable unboiled water position of different aquatic crops also there are differences, plug by the difference of the first supporting leg 41 height that the degree of depth regulates the bottom of drainpipe 4, determine to stop irrigation level with this.Can also arrange scale on the first supporting leg 41 in addition, scale vertically measures, and can determine open-topped height easily by scale, also may be used for anti-inspection and tests actual height of water level.
Thus, when water level increases to stopping irrigation level, float 6 rises, and occluding body 61 is by the bottom shutoff of drainpipe 4, and the bottom of drainpipe 4 is by after shutoff, and water bag 2 turgor tank 1 forms shutoff; When in time irrigating the water level decreasing of field, float 6 declines, occluding body 61 loses the plugging effect of the bottom to drainpipe 4, irrigate and start, under the condition of source of irrigation water abundance, as water Hao can introduce river, river source time, water Hao can accomplish there is water for a long time, namely the real-time automatic makeup realizing moisture by this device to, completely without the need to personnel guard, and the waste of water resource can not be caused, stop irrigation level can being set in the optimum growh water level of crop in addition, crop is in all the time in optimum level of water growth, can output be improved.
In addition, also by this automatic irrigation device composition automatic irrigation system, automatic irrigation is carried out to multistage trapezoidal field, concrete, each this automatic irrigation device is arranged at different levels waiting to irrigate between field, and between field at the highest level and water Hao, along at different levels, water source waits that irrigating field flows down step by step, first the field of minimum one-level reaches stopping irrigation level, and then the water bag 2 turgor tank 1 in the tank 1 be communicated with between its with upper level field, the field of upper level also can reach stopping irrigation level thereupon again, upwards transmit successively with this, until highest level field reaches stopping irrigation level, again by automatic tank 1 shutoff will be connected with water Hao of water bag 2, thus complete the automatic irrigation in whole paddy field.In addition when needing to carry out emptying to all fields of terraced fields, only the mouth of a river of most first order field need be opened, the water of whole terraced fields just can automatic-discharging, saves manpower greatly.
For adult crop, about the height of water level of normal irrigation is set in the optimum growh water level of crop, well below the tolerance height of water level of actual crop, when rainfall occurs, water bag 2 can bulge further with the rise of field water level, continue to wait that the tank 1 of irrigating field forms shutoff at different levels, realize the automatic accumulation to rainwater thus.In addition, for making water bag 2, there is the better effect that bulges in the vertical, baffle plate 12 can be set at the two ends of tank 1, for limit water bag 2 along tank 1 groove to bulge, make more the generation in the vertical that bulge of water bag, improve the height that bulges of water bag 2, also therefore, it is possible to collect more rainwater resource; And baffle plate 12 can also form stop to water bag, anti-sealing slips along tank.
But for the accumulation of rainwater, can not unconfinedly carry out, the highest tolerance water level that can not exceed aquatic crops, otherwise can affect plant growth, to this, the tank 1 of this device is also provided with height limiter, for limiting the height that bulges of water bag 2, after water level reaches spacing height, water can be discharged by the top of water bag 2 and be flowed away, thus forms restriction to peak level.Height limiter can be specifically be connected to the gag lever post above tank 1, and the top due to water bag 2 is inner floating kickboard 3, and gag lever post being set to two can reach limit effect.
The spacing height of height limiter is preferably set to adjustable in addition, specifically can in the difference perforate of the sidewall differing heights place of tank 1, differing heights place gag lever post being plugged in sidewall is formed spacing, such as the paddy rice in seedling stage, the spacing height of height limiter is arranged on 3 centimetres, and that rainfall can be avoided like this to cause floods seedling phenomenon.When practical application, only when crops seedling stage, height limiter need be arranged the spacing height that prevents from flooding seedling, and to be used as after growing tall, then the tolerance being set to crop highly, whole process of growth only need operate twice to height limiter.
Embodiment two
A kind of automatic rice paddy irrigation system that the present embodiment two provides, substantially identical with the structure of embodiment one, something in common repeats no more, and difference is:
Shown in composition graphs 1 and Fig. 2, the open-topped rational height of float chamber 5 equals the stopping irrigation level height of waiting to irrigate field; Float 6 is plugged in the open top of float chamber 5, at the top of float 6, and be positioned at the outer of occluding body 61 and be arranged with outer rim 62, outer rim 62 directly enters into float chamber 5 for the water preventing drainpipe 4 and discharge, but the water that drainpipe 4 is discharged flow into along outer rim 62 and waits to irrigate in field; In bottom opening, activity is inserted with floating valve block 7, the external diameter of floating valve block 7 is less than the bore of bottom opening, one end that floating valve block 7 is not inserted into float chamber 5 is provided with annular shutoff 71, and annular shutoff 71 forms contact seal for the buoyancy and bottom opening utilizing floating valve block 7.
Open-topped height due to float chamber 5 equals the height stopping irrigation level, when extraneous water level reaches float chamber 5 open-topped height, water can flow in float chamber 5, and the float 6 of float chamber 5 inside floats, and the occluding body 61 at float 6 top is inserted into the bottom formation shutoff of drainpipe 4.
The bottom of drainpipe 4 is by after shutoff, and the delivery port of water bag 2 stops water outlet, and under the effect of the kickboard 3 in water bag 2, water source is continuously introduced in water bag 2, until the water level in water bag 2 is fair with water level.In this process, water bag 2 bulges, and forms shutoff to tank 1, to be flow into wait to irrigate in field for preventing water source by tank 1.
When irrigating, along with waiting that the paddy field irrigating field raises, floating valve block 7 rises to the bottom opening formation shutoff of float chamber 5 gradually, until water level rises to when maintaining an equal level with the open top of float chamber 5 (stopping irrigation level), current flow into float chamber 5 and are filled, float 6 floats, and the bottom of occluding body 61 pairs of drainpipes 4 at float 6 top forms shutoff, irrigates and stops.
When reducing gradually through evaporation and Crop wait the water level of irrigating field, the buoyancy of water in paddy field to floating valve block 7 is greater than water in float chamber 5 to the downward pressure of floating valve block 7, according to stress balance principle, the annular shutoff 71 of floating valve block 7 still has relative pressure with the bottom opening of float chamber 5 and keeps sealing, so the annular shutoff 71 of floating valve block 7 can't lose plugging effect immediately, until paddy field water level is reduced to need irrigation level, the buoyancy of water now in paddy field to float 6 is decreased to the pressure equaling float chamber 5 pairs of floats 6, thus make to lose relative pressure between the annular shutoff 71 of floating valve block 7 and bottom opening, thus temporarily lose plugging effect, for reaching new balance, water level in float chamber 5 can slightly decline, floating valve block 7 is made to form shutoff again.
Due to the buoyancy size needing irrigation level height to depend on floating valve block 7, differing heights is needed to the determination of irrigation level, by arranging cavity body structure in the inside of floating valve block 7, floating block (as foam etc.) can be inserted in cavity, by inserting the floating block of different amount, make the displacement of volume of floating valve block 7 adjustable, regulate the buoyancy size of floating valve block 7 with this.Thus can for different aquatic cropss, or for the different growing stages of same origin, arranging different needs irrigation level.
The one end that also can be inserted into float chamber 5 at floating valve block 7 in addition arranges position-limited claw, skid off from bottom opening for preventing floating valve block 7, position-limited claw is preferably set to tilt obliquely, and there is elasticity, and when floating valve block 7 is inserted in the bottom opening of float chamber 5, position-limited claw radial contraction, when position-limited claw is inserted into after in float chamber 5, position-limited claw opens, and is limited at the top of floating valve block 7 in float chamber 5, easy for installation.
The present embodiment two is applicable to the situation not having long-term source of irrigation water, and namely water Hao can not ensure there is water for a long time, when needed well water can only be pumped into Shui Haozhong and irrigate.For the management in trapezoidal paddy field, irrigation every day one can not be accomplished, and for the aquatic crops grown up, it has certain tolerance range to the height of water level, the water level tolerance range of such as paddy rice is at 5-15 centimetre, its optimum growh water level is at 8 cm, when the system formed utilizing this device is irrigated, many days demands are met for making once to irrigate, the open top of float chamber 5 can be arranged on 10 centimetres high, when the water level of next stage field reduces, floating valve block 7 can not be opened immediately, due to and field at the highest level cannot in real time from water Hao obtain water source, therefore next stage field is avoided constantly to the phenomenon of the field generation water level at the highest level deficit that upper level field Suo Shui causes, and when rainfall occurs, first rainwater makes up the water level loss in each field, and then by bulging of water bag 2 rainwater collected again.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and replacement, these improve and replace and also should be considered as protection scope of the present invention.
