Automatic partition structure for trapezoidal channels

Abstract

Based on the analysis of existing and proposed designs of automatic gate structures, as well as the design of an automatic water level regulator on the canal developed earlier with F.A.Kadirov, a design of a mobile automatic partition structure in the form of an automatic shutter for channels of a trapezoidal section of irrigation systems was developed. And also, based on model studies conducted by the author, the flow coefficient is determined, and a formula for determining the throughput of this design is given. This design is made in the form of a gate, which is a container formed by a rigid bottom, pressure, and spillway parts of the flexible rubberized meliorative fabric, passing into flexible side elements. The level control in front of the partition structure is carried out with the help of a level controller. This partition structure does not require large expenditures; it can be portable or stationary, it is not metal-intensive, lightweight, transportable, combines the functions of stabilizing the required water level in the channel, dumping excess water, fin, and debris, and provides the necessary water inflow into the discharge channels.
