Armally supplied by a photovoltaic water supply system for irrigated irrigation devices

Abstract

The invention belongs to the technical field of irrigation, and in particular relates to a photovoltaic water supply system for a novel sprinkler of a novel pressureless irrigation device. Photovoltaic water lifts into the reservoir, and there is an overflow pipe on the upper part. The water inlet pipe from the reservoir is connected to the horizontal port of the positive tee in the water supply water level control tank. The upper port of the positive tee passes through the upper connecting pipe, the inner wire joint and the four corner Plug connection, the lower port of the positive tee is connected to the water distribution pipe through the lower connecting pipe, the ball valve, and the right and left ends of the upper connecting rod are respectively set on the upper right shaft on the upper connecting pipe and the upper left shaft on the sleeve, and the lower The right end of the connecting rod is fixed on the valve stem, and the left end is perforated and placed on the lower left shaft on the sleeve. The distance between the upper right shaft and the upper left shaft is equal to the distance between the valve stem and the lower left shaft, and the distance between the upper right shaft and the valve stem is the same as that of the upper left shaft. The distance of wheelbase left lower shaft is equal, and the buoyant tank connecting rod is in the sleeve, and the top of the buoyant tank connecting rod has the control water level scale, and the sleeve top has the control water level positioning pin. Sturdy and durable, the control water level is easy to adjust.

Description

Technical field: [0001] 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. Background technique: [0002] 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 ...

Problems solved by technology

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 tillage 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 zone through soil capillary water rise

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, it is necessary to provide a special photovoltaic water supply system for the irrigator of the pressureless irrigation device.
