Water supply device for field pipeline irrigation

Abstract

A water supply device for field pipeline irrigation belongs to the technical field of agricultural irrigation and is in a semi-fixed split combined structure. A lower bolt is disposed in a concrete pipe, a connector, a water outlet and an upper bolt are disposed at the top end of the lower bolt, and an upper bolt cap, a fastener and an anti-inversion fastener are disposed on a bend of the upper bolt. A start and stop handle is disposed inside the upper bolt. A plurality of self-closing water division wings are disposed on a mushroom-shaped edge of a water stop valve. A boss and a sleeve are disposed at the center of the lower surface of the water stop valve. A float chamber at the top end of a screw is reserved in the sleeve, and a float is disposed in the float chamber. A plurality of lower exhaust holes are reserved on the periphery of the lower end of the float chamber. A deformed nut used with the sleeve of the water stop valve is used for fastening the float chamber and the water stop valve together through a clamping disk. The screw is disposed in a nut thread insert supported by a support bar, a reducing connecting pipe is connected to the outer end of the support bar, and the reducing connecting pipe is sleeved to the upper portion of the lower bolt and the lower portion of the lower bolt to form a combined lower bolt. A lower pipe opening of the lower bolt is connected with a sewer tee water outlet pipe, and the upper bolt and the lower bolt form the water supply device.

Description

technical field [0001] The invention belongs to the technical field of agricultural irrigation. Background technique [0002] my country is a large agricultural country and one of the countries with serious shortage of water resources. The per capita water resources are only 1 / 4 of the world value. Agricultural water consumption accounts for 70% of the total water consumption of the national economy. At present, most of the farmland irrigation in my country still continues the irrigation methods of soil canal water delivery and large and small flood irrigation. There is a huge potential for agricultural water saving. With the implementation of the country's strict water resource management system, a water-saving society, especially agricultural water-saving projects, will develop rapidly. Pipeline irrigation, as the main form of agricultural water-saving projects, is especially suitable for field crop water-saving projects. Very broad. [0003] The farmland pipeline water ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a farmland pipeline irrigation water supply device to solve the poor sealing and locking performance of the existing water supply device, easy to steal, easy to rust, easy to open, and individual farmers to open water without authorization, resulting in disorderly irrigation. As a result, downstream farmers cannot obtain the normal required water, which affects the overall water supply plan

Its supporting protection device, the concrete pipe protection well, generally exposes the exposed part of the ground more than 0.5 meters above the ground level, which affects the operation of agricultural machinery and farmers' operations, and is easy to collide and damage the water supply device.
