Abstract

To determine the throughput of the automatic gate of the flushing device, which is part of the hydraulic automatic water level controller with flexible working bodies, developed by the author together with Ya.V. Bochkarev, experimental studies were conducted. They were carried out by the method of physical modeling of the model and nature on an experimental installation, with the installation of two models of an automatic shutter: a) with a fixed angle of inclination of the pressure board, b) with an automatic shutter in the form of a container consisting of a rigid board under pressure in front of it and a rubberized fabric, as part of an automatic water level regulator. Based on the results of these studies, formulas and dependencies were obtained to determine the flow rates without taking into account and taking into account the lateral outflows and lateral compression coefficients and the water flows passing through the automatic gate.

Highlights

The modern tendencies and scales of development of hydraulic engineering and land reclamation are put forward - the problem of effective management of the water level in irrigation systems
The model of the automatic gate for washing sediments consisted of a container 3 with a pressure part in the form of a rigid shield 1, forming together with an elastic material made of rubberized fabric 2, with a length of 0.09 m and a width of 0.37 m on the non-pressure side and passing into the side elements of the automatic gate
Values of the factor of the expense μ at the expiration from under a shutterautomatic machine of the washing device in the absence of the lateral expirations tend to increase with corner reduction between a pressure head side of water containing shutterautomatic machine of the washing device and horizontal that speaks increase in the height of a water throughput aperture and factor of vertical compression ε

Summary

Introduction

The modern tendencies and scales of development of hydraulic engineering and land reclamation are put forward - the problem of effective management of the water level in irrigation systems. Due to the massive use of shutters on partition structures of irrigation systems and their remoteness from power lines, among them, from the point of view of economic efficiency, structures using automatic hydraulic gates are most effective since they work using hydraulic energy of a moving water stream. They found the greatest application on partition structures of irrigation canals, structures developed and described in the works of Sh.S. Bobokhidze [1], Ya.V. Bochkarev [2], [3], [4], N.А. The main thing in these structures is a metal shutter (flat, segment, valve, sector) of one design or another, the requirement for them to have significant water level drops, preventing water overflow through the top of the shutter, the need for periodic mechanical cleaning of the space in front of the shutters from floating objects and debris, the need in capital structures
