Problems solved by technology

Among them, the manual observation method is often used by most researchers because of its simple operation. This method requires a lot of manpower, and the accuracy of the experimental data obtained by this method is low; the surface water flow automatic monitoring system developed by using the infrared principle is relatively high. High makes the range of use limited

Embodiment Construction

[0024] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] exist figure 1 Among them, the test system of the present invention is composed of a test soil body, a water supply device, an automatic video collection device for surface water flow, an automatic soil moisture collection device and an evaporation device.

[0026] The test soil in this embodiment is located in the soil tank and is a homogeneous soil with a particle diameter of less than 2 mm, which is compacted to the design bulk density by layering and segmenting. The soil tank is 8.0×1.2×1.0m 3 The hollow cube structure is provided with a drainage channel along the length direction of the soil tank at the bottom. An irrigation ditch is designed on the surface ...

Abstract

The invention discloses a test system used for simulating the law of surface irrigation water flow motion, comprising a tested soil body with an irrigation ditch on the surface; a watering device which is connected with the tested soil body through the irrigation ditch and supplies water for the soil body, comprising a water storage vessel, a flow tube, a water lifting unit, a conduit pipe and an energy dissipating water tank; and a surface water flow automatic video acquisition device which comprises a graduated scale arranged in the irrigation ditch, an image acquisition device, an image collecting device and an image display device. The law of surface irrigation water flow motion can be simulated through the system. The system has the advantages of comprehensive and accurate functions, high reliability and low cost.

Description

technical field [0001] The invention relates to the field of water-saving irrigation equipment, in particular to a test system for simulating the law of water flow movement. Background technique [0002] At home and abroad, a lot of work has been done on the law of irrigation water flow movement. At present, there are two methods for measuring water depth changes in the process of irrigation water flow movement: manual measurement and infrared measurement. Among them, the manual observation method is often used by most researchers due to its simple operation. This method requires a lot of manpower, and the accuracy of the experimental data obtained by this method is low; the surface water flow automatic monitoring system developed by using the infrared principle has high accuracy. High makes the range of use limited. Contents of the invention [0003] The purpose of the present invention is to provide a test system that can accurately, visually and quantitatively simulate...
