Description
技术领域technical field
本实用新型涉及农业灌溉技术，尤其是一种节水灌溉装置。The utility model relates to agricultural irrigation technology, in particular to a water-saving irrigation device.
背景技术Background technique
地面灌溉技术是世界广泛应用的一种灌溉方式，也是我国传统的一种灌溉方式，占我国总灌溉面积的90%以上，而且在相当长时间内地面灌溉仍将占主导地位。华北平原大部分地区都采用过去的沟畦地面灌溉。目前我国灌溉水利用效率较低，这主要是由于田间灌溉工程设施的不完善、畦(沟)规格和入地流量不合理、土地平整状况差以及田间灌溉管理措施粗放等原因所致。在目前水资源日益短缺，压采任务越来越重的情况下，亟需对畦灌节水技术开展深入研究。Surface irrigation technology is an irrigation method widely used in the world, and it is also a traditional irrigation method in my country, accounting for more than 90% of the total irrigated area in my country, and surface irrigation will still dominate for a long time. Most areas of the North China Plain are irrigated with the old furrows and furrows. At present, the utilization efficiency of irrigation water in my country is low, which is mainly due to the imperfection of field irrigation engineering facilities, unreasonable furrow (ditch) specifications and inflow flow, poor land leveling, and extensive field irrigation management measures. In the current situation where water resources are increasingly scarce and the mining pressure task is getting heavier, it is urgent to carry out in-depth research on border irrigation water-saving technology.
当前在华北平原，大部分农户或农民地面灌溉一般采用沟灌方式，畦田面积一般控制在50m2左右，畦宽5-6m左右，虽然，在小畦灌和长畦短灌日渐得到大面积应用的情况下，农民在灌水过程中，已经注意到了小面积灌溉的好处，但是依旧存在许多问题：① 灌水量过大，直到整个小畦全部灌饱和，才进行改水。表面是小畦灌溉，实则是“小畦漫灌”；②畦间输水仍然多采用小面积沟渠输水，一方面是土地资源的浪费，一方面是沟渠由大量水渗漏；③水龙带与水龙带之间的连接多是直接通过滑槽接头和扣爪接头互相配合进行固定联接或是通过多通接头连接，在灌溉过程中直接的固定连接使得人工改水过程中水龙带容易弯折打结，造成水龙带局部水压加大容易使水龙带崩裂，多通接头连接虽然使得操作简单但也增加了成本。At present, in the North China Plain, most farmers or farmers generally use furrow irrigation for surface irrigation. The area of the border field is generally controlled at about 50m2, and the width of the border is about 5-6m. In the process of irrigation, farmers have noticed the benefits of small-area irrigation, but there are still many problems: ① The amount of irrigation water is too large, and the water is not improved until the entire small border is fully irrigated. On the surface, it is small-scale irrigation, but in fact it is "small-scale flood irrigation"; 2. Small-area ditches are still used to transport water between the furrows. On the one hand, it is a waste of land resources, and on the other hand, the ditches leak a lot of water; The connection between the hoses is mostly fixed directly through the cooperation of the chute joint and the claw joint or through the multi-way joint. The direct fixed connection during the irrigation process makes the hose easy to bend and break during the manual water change process. knot, causing the local water pressure of the water hose to increase and easily make the water hose burst. Although the multi-way joint connection makes the operation simple, it also increases the cost.

参看附图，本实用新型的工作原理在于：在微畦种植模式下，通常畦田规格以20m2左右为宜，因地制宜，长5-6m，宽4-5m，畦田长与宽接近，畦田需要整理平整。一般可以通过下面的方法确定灌水定额，以冬小麦为例，全生育期耗水量450mm，土壤100-120cm储水能力为400mm，若采用一次灌水，目标湿润层为100-120mm，若采用两次灌水，则目标湿润层为80-100mm。Referring to the accompanying drawings, the working principle of the utility model is: under the mode of micro-farm planting, the size of the border field is generally about 20m 2 , which is adapted to local conditions, length 5-6m, width 4-5m, the length and width of the border field are close, and the border field needs to be sorted smooth. Generally, the irrigation quota can be determined by the following method. Taking winter wheat as an example, the water consumption in the whole growth period is 450mm, and the water storage capacity of 100-120cm of soil is 400mm. If one irrigation is used, the target wet layer is 100-120mm. If two irrigations are used , the target wetting layer is 80-100mm.
采用本实用新型的灌溉装置后，可以取消80-100 cm 的输水沟，保留40cm左右供输水管道通过，可以多种3-4行作物。使用时，一组水龙管段1与波纹管段2的组合与两畦畦田长度相当（起止端例外），且波纹管段2末端（作为浇灌开口）开口于四块畦田的交叉点，从而实现一口四田的灌溉效果。在供水量为30 m3/hr的条件下，每个小畦需要灌溉2-3分钟。小畦面积过小，操作者就会手忙脚乱，顾此失彼，如果小畦面积过大，既浪费水资源，也浪费工时。然后通过畦田的划分确定水龙带的分布情况，采用人工改水控制灌水量。灌溉前测定土壤水分状态，用目标湿润层储水能力减去土壤本身含水量即为灌溉定额，通过控制调节阀门和水表来定量灌溉，也可以根据每个微畦所需灌溉量设定数字式调节水阀实现间断供水，按照设定每供水一段时间后停顿片刻再行继续供水，停顿时间间隔内灌溉员进行水龙管带和波纹管带的拆-装，使得管路开口顺序移至下一组微畦。使用塑料水龙带输水，用转接口切换灌溉小畦非常轻松、简单，每断开一个接头，可以浇灌4个相邻小畦。转接口切换的便利源于本实用新型的转接口设计：接头的一头是滑槽接头，另一头为扣爪接头，二者内扣连接，能够快速的密封对接和拆下，只需用手一拧即可完成拆装，具体的，将弧形凸块对接插入弧形断口并沿弧形槽的开口旋转至其封口，实现滑槽接头与扣爪接头的对接连接；反之实现拆卸操作；两水龙带之间采用可以折叠式的聚乙烯材质的波纹塑料管，因为其弯曲性能好，非常容易更改水龙带的水流及水口方向，可在不移动的情况下，连续灌溉4块畦田，并且塑料管沿折叠伸缩方向具有管状弹性可以收缩进去，便于携带。After adopting the irrigation device of the utility model, the 80-100 cm water delivery ditch can be canceled, and about 40 cm can be reserved for the water delivery pipeline to pass through, so that 3-4 rows of crops can be planted. When in use, the combination of a set of water hose section 1 and bellows section 2 is equivalent to the length of two border fields (except for the start and end ends), and the end of bellows section 2 (as an irrigation opening) opens at the intersection of four fields, so as to realize a four-field field irrigation effect. Under the condition of water supply of 30 m 3 /hr, each small plot needs to be irrigated for 2-3 minutes. If the area of the small border is too small, the operator will be in a hurry and lose sight of the other. If the area of the small border is too large, it will waste both water resources and man-hours. Then, the distribution of the water hoses was determined through the division of the border fields, and the amount of irrigation was controlled by artificial water modification. Measure the soil moisture state before irrigation, and subtract the water content of the soil itself from the water storage capacity of the target wet layer to obtain the irrigation quota. Quantitative irrigation can be performed by controlling and adjusting the valve and water meter, and digital irrigation can also be set according to the amount of irrigation required for each micro-plot. Adjust the water valve to achieve intermittent water supply. According to the set water supply for a period of time, stop for a while and then continue the water supply. During the pause interval, the irrigator will disassemble and install the hose belt and the bellows belt, so that the pipeline opening sequence will move to the next one. Group micro border. It is very easy and simple to use plastic hoses to transfer water and use the adapter to switch irrigation small plots. Every time a joint is disconnected, 4 adjacent small plots can be irrigated. The convenience of switching the adapter stems from the design of the adapter of the utility model: one end of the joint is a chute joint, and the other end is a claw joint. Twist to complete the disassembly and assembly. Specifically, insert the arc-shaped bump into the arc-shaped fracture and rotate along the opening of the arc-shaped slot to its seal to realize the butt connection between the chute joint and the claw joint; otherwise, the disassembly operation is realized; The corrugated plastic pipe made of polyethylene material that can be folded is used between the hoses. Because of its good bending performance, it is very easy to change the water flow and the direction of the nozzle of the hose. It can continuously irrigate 4 fields without moving, and the plastic The tube has tubular elasticity along the folding and stretching direction and can be shrunk in, making it easy to carry.
上述描述仅作为本实用新型可实施的技术方案提出，不作为对其技术方案本身的单一限制条件。The above description is only proposed as an implementable technical solution of the utility model, not as a single restriction on the technical solution itself.
