An automatic control device for diverting water from main canals to branch canals

Abstract

The invention relates to an automatic regulating and controlling device for disturbing water from a main canal to branch canals. The automatic regulating and controlling device comprises detachable door grooves, double doors, a linkage rod and a floating assembly. The double doors are arranged on the inner side of a water inlet pipe of a water distribution well through the detachable door grooves. The lower portion of the linkage rod is connected with the double doors, and the upper portion of the linkage rod is connected with the floating assembly. The floating assembly comprises an empty tank bearing stand used for containing water, and a flap valve used for preventing water from flowing backwards is arranged in the empty tank bearing stand. When the water level of the water distribution well rises, water enters the empty tank bearing stand of the floating assembly, the floating assembly rises under the buoyancy effect at the same time, the linkage rod is driven to move upwards accordingly, and the double doors are driven by the linkage rod to be closed; and when the water level of the water distribution well falls, the floating assembly descends under the effect of the self weight of the floating assembly and the self weight of the water in the empty tank bearing stand, the linkage rod is driven to move downwards accordingly, and the double doors are driven by the linkage rod to be opened. Compared with the prior art, the automatic regulating and controlling device has the advantages that the flow of all the branch canals is made balanced, the water levels of the branch canals are effectively controlled, and management is convenient.

Description

technical field [0001] The invention relates to a water diversion control device, in particular to an automatic control device for diverting water from a main canal to a branch canal. Background technique [0002] In order to realize the comprehensive arrangement of fields, water, roads, forests and villages, increase the area of ​​effective arable land, improve the supporting level of agricultural infrastructure, improve agricultural production conditions and ecological environment, improve the level of mechanized farming, promote large-scale agricultural operation, and promote rural construction and modernization Agricultural development, the country is actively developing land development and consolidation projects. Land development and consolidation can be divided into three types: land consolidation, land reclamation, and land development. The implementation of land development and consolidation projects includes land leveling, water source engineering, irrigation engi...

AI Technical Summary

Problems solved by technology

However, for land development and consolidation projects, the water quality of the irrigation water source is average, and there are many suspended substances in the water; the diameter of the pipeline diverting water from the main canal to the branch canal is large, and the flow rate is also large; the operation management is relatively extensive. From the perspective of project investment and operation management, Generally, considering the characteristics of automatic control, conventional water level and flow control devices are not suitable for land development and consolidation projects.
