Farmland surface water management and control system and manufacturing method, and farmland surface water management and control drainage and irrigation method

Abstract

The invention provides a farmland surface water management and control system and a fabrication method thereof as well as a farmland surface water management and control / irrigation and drainage method. A surface water management and control facility is arranged along the riverbed of a river channel according to the farmland irrigation plan of a region; the surface water management and control facility is composed of a surface water irrigation metering control cabinet, a water storage well, a water guide opening, a water guide pipeline and a water delivery pipeline; the surface water irrigation metering control cabinet is fixedly mounted on the top of the water storage well; a surface water controller, a power distributor and a communication antenna are mounted in the surface water irrigation metering control cabinet; the surface water controller is connected with the power distributor by use of a line; the power distributor is connected with the switch of a submerged pump by use of a circuit; the surface water controller sends an instruction to the power distributor by use of the line to turn on or turn off the submerged pump; the surface water controller transmits the data information acquired by the surface water controller to a agricultural water resource management and control center by use of the communication antenna. The farmland surface water management and control system is scientific in design, reasonable in structure, low in cost, and simple to fabricate, and supports warning on insufficient balance, warning on instrument metering faults, warning on door opening and warning on pump faults.

Description

technical field [0001] The invention relates to drainage and irrigation of a pumping station, in particular to a farmland surface water management and control system and a manufacturing method thereof, and a method for farmland surface water management and control drainage and irrigation. Background technique [0002] Since the 1980s in my country, pumping irrigation and drainage is a comprehensive water conservancy project that converts electrical energy into water energy for farmland drainage and irrigation, water supply, waterlogging drainage and cross-basin water transfer. The only source of power for resource allocation is an important engineering measure to solve flood disasters, droughts and water shortages, and one of the important symbols to realize water conservancy modernization. Pumping station drainage and irrigation projects have played a huge role in the development of industrial and agricultural production and urban and rural water supply. [0003] There are ...

AI Technical Summary

Problems solved by technology

[0003] There are also some problems in the drainage and irrigation construction of pumping stations: First, the high investment in project construction

Second, the modernization of the pumping station is seriously behind, lack of water metering measures, and the phenomenon of flood irrigation is common, resulting in a great waste of water resources

The third is to establish a pumping station for drainage and irrigation in a region, which cannot control the water intake of the pumping station as a whole, and cannot regulate the surface water in a region, so that the surface water can be used rationally
