| 摘要: |
| 【目的】以水力驱动灌溉控制阀（Hydraulic Actuated Irrigation Control Valve, HAICV）为核心，构建了水力驱动自动灌溉系统，针对HAICV独特的工作特性，开展了与之适配的田间管网设计研究。【方法】在介绍水力驱动自动灌溉系统组成及工作原理的基础上，对比不同灌水小区方案的管材用量与管网是否规整，针对系统运行中流量压力过高的问题，提出分级控制的阀门组合结构，并对比分析其流量与灌溉周期；评估水力驱动自动灌溉系统经济可行性及可靠性。【结果】HAICV位于灌水小区中心，连接管“X”形布置为水力驱动自动灌溉系统灌水小区的最优布置方案，且采用二级控制阀门组合的田间管网结构最优；与传统自动灌溉系统相比，水力驱动自动灌溉系统基础投资降低35.67%，年运行费用减少28.60%；阀门启闭时间慢，灌溉执行准确率基本持平。【结论】基于HAICV二级控制组合田间管网结构的水力驱动自动灌溉系统可满足自动灌溉需求，尤其适用于电网与通信网络覆盖率低的区域。 |

| Abstract: |
| 【Objective】Automatic irrigation improves irrigation efficiency and reduces labor costs, but its application is constrained in areas with limited access to electricity and communication networks. We developed a hydraulically actuated automatic irrigation system based on a hydraulically actuated irrigation control valve (HAICV) to overcome these limitations and investigated field pipe-network configurations suited to its operation.【Method】Based on the composition and operating principles of the hydraulically actuated automatic irrigation system, material requirements and network configurations among different irrigation plot layouts were compared. To address excessive flow rate and pressure during system operation, a hierarchical control-valve assembly structure was proposed, and its flow characteristics and irrigation cycles were compared and analyzed. The economic feasibility and operational reliability of the hydraulically actuated automatic irrigation system were evaluated.【Result】The HAICV was optimally positioned at the center of the irrigation plot, with an ‘X’-shaped connecting-pipe layout providing the optimal field pipe-network configuration. The field pipe network with a two-stage control-valve assembly showed the best overall performance. Compared with a traditional automatic irrigation system, the hydraulically actuated automatic irrigation system reduced initial investment by 35.67% and annual operating costs by 28.60%. Although the valve opening and closing processes were relatively slow, irrigation control accuracy was comparable to that of the traditional system.【Conclusion】The hydraulically actuated automatic irrigation system based on the optimized field pipe network and two-stage HAICV configuration can meet the requirements of automatic irrigation while substantially reducing initial investment and annual operating costs. It is particularly suitable for agricultural areas with limited electricity and communication network coverage. |
