Assembled water conveying and distributing type water-saving irrigation device for paddy field
The invention relates to a water-saving irrigation device for a paddy field, in particular to an assembled water conveying and distributing type water-saving irrigation device for a paddy field. The assembled water conveying and distributing type water-saving irrigation device for the paddy field aims to solve the problems of large water leakage, small canal water utilization coefficient, low canal system strength grade, over-low anti-freezing grade, large occupied area, long construction period and short service life due to the fact that traditional soil canals and laid concrete plates are used for farmland irrigation in the prior art. The assembled water conveying and distributing type water-saving irrigation device for the paddy field comprises a prefabricated part, a gate, a four-way joint, a three-way joint, an elbow, a prefabricated integral bucket agricultural door, a field culvert, a steep slope, a reducer and an integral rectangular canal. According to the assembled water conveying and distributing type water-saving irrigation device for the paddy field, the water utilization coefficient is 0.95, so that the field water consumption can be greatly reduced, the average water saving per mu can reach 100m <3>, and the water utilization efficiency of crops can be improved to 1.84 kg/m <3>; the land utilization rate is improved by more than 1%. The assembled water conveying and distributing type water-saving irrigation device for the paddy field can be obtained.
一种装配型输配水式水田节水灌溉装置，它涉及一种水田节水灌溉装置。本发明的目的是要解决现有农田灌溉使用传统的土渠和铺设混凝土板块存在水渗漏量很大，渠道水利用系数较小，渠系强度等级低，抗冻等级过低，占地大、施工期长和使用寿命短的问题。一种装配型输配水式水田节水灌溉装置包括预制构件、闸门、四通、三通、弯头、预制整体斗农门、进地涵、陡坡、变径和整体矩形渠。一种装配型输配水式水田节水灌溉装置的水利用系数0.95，可使田间用水大幅降低，平均亩节水可达到100m3，农作物水分利用效率可提高到1.84kg/m3；土地利用率提高1％以上。本发明可获得一种装配型输配水式水田节水灌溉装置。
