Problems solved by technology

[0004] With the continuous development of water measuring technology in irrigation areas, new water measuring facilities such as "wing-shaped water measuring tanks" have emerged. However, when applied to plain irrigation areas, the head loss caused by water measuring tanks still limits their application, and practical applications will still be difficult. Frost heave damage, maintenance, man-made damage and other issues

Embodiment Construction

[0022] A measuring tank that integrates the functions of measuring and adjusting channel flow, including channel 1, wing column 3, insert plate 5, rubber bottom plate 2, and fixing bolts 4. The channel 1 is a rectangular concrete structure, and a rubber bottom plate 2 is installed at the bottom of the measuring tank at the rectangular channel 1, and the rubber bottom plate 2 is fixed on the bottom surface of the channel 1 by fixing bolts 4. The cross-sectional shape of the wing cylinder 3 is the wing-shaped cylinder perpendicular to the bottom of the channel, and the cross-sectional shape of the wing-shaped cylinder is given by the equation

Abstract

The invention discloses a measuring flume integrating functions of measuring and adjusting the channel flow. The measuring flume is composed of a channel, a wing cylinder, insertion plates, a rubber bottom plate and a fixing bolt. The insertion plates with different widths are fixed on the side walls of the wing cylinder to form a throat section of the channel; the width of the throat section is the sum of the distance sizes from the widest part of the wing cylinder to the side walls of the rectangular channel; and the width of the throat section can be adjusted through the insertion plates with different widths so as to adjust the channel flow. The measuring flume integrating functions of measuring and adjusting channel flow disclosed by the invention has the advantages of simple structure, high flow measuring accuracy, little head loss and simple and easy-to-use flow formula, is convenient to manufacture and mount, and can adjust the flow.

Description

technical field [0001] The invention belongs to the technical field of irrigation channel flow measurement and control, and relates to an integrated water measuring facility for measuring and controlling channel flow in agricultural water conservancy projects, in particular to a water measuring tank integrating the functions of measuring and adjusting channel flow. Background technique [0002] my country has a vast territory, and agriculture is the main pillar of our economy. Agricultural irrigation water accounts for more than 70% of the national water consumption. With the gradual advancement of new rural construction and the continuous increase of agricultural water supply and irrigation area, it is very necessary to implement water-saving measures. As a large water user, the irrigation district is the focus of water conservation. It is of great significance to agricultural water conservancy projects to do a good job in water conservation, planned water use and scientific...
