Photovoltaic water supply system for novel irrigation emitter of novel non-pressure irrigation device

Abstract

The invention belongs to the technical field of irrigation, and particularly relates to a photovoltaic water supply system for a novel irrigation emitter of a novel non-pressure irrigation device. Photovoltaic lifting water enters an impounding reservoir, the upper part of the impounding reservoir is provided with an overflow pipe, a water inlet pipe from the impounding reservoir is connected with a horizontal end opening of a tee in a water supply level control pool, an upper end opening of the tee is connected with a square plug through an upper connecting pipe and an internal threaded connector, a lower end opening of the tee is connected with a water distribution pipe through a lower connecting pipe and a ball valve, the right end and left end of an upper connecting rod respectively sleeve an upper right shaft on the upper connecting pipe and an upper left shaft on a sleeve after are trepanned, the right end of a lower connecting rod is fixed on a valve rod, the left end of the lower connecting rod sleeves a lower left shaft on the sleeve after is trepanned, the distance between the upper right shaft and the upper left shaft is equal to the distance between the valve rod to the lower left shaft, the distance between the upper right shaft and the valve rod is equal to the distance between the upper left shaft and the lower left shaft, a buoyancy tank connecting rod is arranged in the sleeve, the upper part of the buoyancy tank connecting rod is provided with a water level control gauge, and the upper part of the sleeve is provided with a water level control locating pin. The photovoltaic water supply system is firm and durable, and water level can be controlled and adjusted conveniently.

Description

Technical field: [0001] 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. Background technique: [0002] Publication No. CN102160518A is an invention patent—a new pressureless irrigation device, which adopts 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...

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 application number is the invention patent of 201510655256.0 - a new type of sprinkler for a new pressureless irrigation device. If the photovoltaic pumping method is used to supply water, because the water supply tank of the water supply system of the new type of pressureless irrigation device with the publication number CN102160518A needs to be closed for operation ( For details, see the patent specification of "New Pressureless Irrigation Device"), water cannot be filled at any time, so that the invention patent with application number 201510655256.0 - a new type of irrigation device for a new type of pressureless irrigation device, cannot continue to use the publication number CN102160518A 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 new type of pressureless irrigation device must be provided.
