Abstract

The invention discloses a system for testing sprinkling irrigation uniformity under an indoor windy environment, which comprises a water outlet main, nozzles are connected to the water outlet end of the water outlet main through branches, water pressure gauges are connected to the outsides of the branches, a first water pressure control valve, a second water pressure control valve, a third water pressure control valve and a fourth water pressure control valve are respectively mounted inside the branches, a fixed frame is arranged on the outside of the water outlet main, and a controller and awind speed sensor are respectively mounted inside the fixed frame. By means of the first water pressure control valve, the second water pressure control valve, the third water pressure control valve and the fourth water pressure control valve arranged inside the four branches, when a test is carried out, water pressures of the different nozzles can be adjusted according to different wind directions and wind speeds, a preset wind force value and a corresponding wind direction and water pressure control valve, and thereby, not only is sprinkling irrigation is more uniform, but also the objectiveof saving water is achieved; and the system is safe and convenient to use.

Description

technical field [0001] The invention belongs to the technical field of sprinkler irrigation detection, in particular to a test system for uniformity of sprinkler irrigation in an indoor windy environment. Background technique [0002] With the continuous development of agricultural refinement, the requirements for the uniformity of sprinkler irrigation are gradually increasing, so as to reasonably meet the water demand of crops, save water as much as possible while ensuring the normal growth of crops, and realize the sustainable use of water resources. . [0003] Chinese patent application CN105652028A discloses a sprinkling speed detection device for a reel type sprinkler irrigation machine. A built-in bearing 7 and a hollow shaft encoder 8 are arranged at the position below the 5, and a pressing rod 3 and a detection wheel 6 are arranged in the interval of the suspension rod. The lower end is connected, the compression wheel 4 is set on the compression rod 3, one end of ...
