Description
技术领域：Technical field:
本发明属于灌溉技术领域，尤其涉及一种无压灌溉装置的灌水器用光伏供水系统。The invention belongs to the technical field of irrigation, and in particular relates to a photovoltaic water supply system for an emitter of a pressureless irrigation device.
背景技术：Background technique:
公布号为CN 102160518 A的发明专利——“新型无压灌溉装置”，采用了以U型混凝土槽为基本结构的灌水器(详见“新型无压灌溉装置”的专利说明书)。存在以下缺陷：一是，现场施工需要高精度混凝土浇筑成型设备，存在冻胀伸缩缝防渗处理等一系列技术难题，投入大、施工难度高；二是，混凝土U型槽为脆性材料，容易被冻胀、不均匀沉陷以及耕作机械作业等造成损坏；最重要的缺陷是，不能调节通过土壤毛细管水上升向作物根系层供水的土壤饱和水层的高度。在作物蒸腾耗水量不大，土壤水继续上升至土壤表面而形成棵间蒸发造成表面土壤返盐时，不能通过降低土壤饱和水层的高度来加以解决。同样，也不能通过抬高土壤饱和水层高度的办法来治愈地下灌溉播种后苗期表层土壤供水不足的通病。申请号为201510655256.0的发明专利——无压灌溉装置用灌水器，已经克服了上述缺陷。但是，申请号为201510655256.0的发明专利——无压灌溉装置用灌水器，如果采用光伏扬水方式供水，因为公布号为CN 102160518 A的“新型无压灌溉装置”的供水系统的供水罐，需封闭运行(详见“新型无压灌溉装置”的专利说明书)，不能在任意时刻充水，而使得申请号为201510655256.0的发明专利——无压灌溉装置用灌水器，不能继续使用公布号为CN102160518 A的“新型无压灌溉装置”的供水系统，来实现光伏扬水方式供水，所以，必须提供一种特制的无压灌溉装置的灌水器用光伏供水系统。The invention patent with the publication number CN 102160518 A - "New Pressureless Irrigation Device" uses an irrigator with a U-shaped concrete tank as the basic structure (see the patent specification of "New Pressureless Irrigation Device" for details). There are the following defects: first, on-site construction requires high-precision concrete pouring and forming equipment, and there are a series of technical problems such as anti-seepage treatment of frost heaving expansion joints, which requires a large investment and high construction difficulty; second, the concrete U-shaped groove is a brittle material, which is easy to Damaged by frost heave, uneven subsidence, and farming machinery; the most important defect is the inability to adjust the height of the soil-saturated water layer that supplies water to the crop root layer through soil capillary water rise. When crop transpiration consumes little water and soil water continues to rise to the soil surface to form inter-tree evaporation and return salt to the surface soil, it cannot be solved by reducing the height of the soil saturated water layer. Similarly, the common problem of insufficient water supply to surface soil at seedling stage after subsurface irrigation can not be cured by raising the height of soil saturated water layer. The patent for invention with the application number 201510655256.0—irrigator for pressureless irrigation device—has overcome the above defects. However, the invention patent with the application number of 201510655256.0 - the irrigator for pressureless irrigation device, if the water is supplied by photovoltaic pumping method, because the water supply tank of the water supply system of the "new pressureless irrigation device" with the publication number CN 102160518 A needs to be closed Running (see the patent specification of "New Pressureless Irrigation Device" for details), it cannot be filled with water at any time, so that the invention patent with application number 201510655256.0 - the irrigator for pressureless irrigation device cannot continue to be used. The publication number is CN102160518 A The water supply system of the "new pressureless irrigation device" is used to realize the water supply by means of photovoltaic water pumping. Therefore, a special photovoltaic water supply system for the emitter of the pressureless irrigation device must be provided.
