Rice field water viewer and rice field water level control method

Abstract

The invention provides a rice field water viewer and a rice field water level control method. The rice field water viewer comprises a cavity, a water level measurer is arranged in the cavity, and a water level obtaining mechanism is arranged outside the water level measurer. The water level obtaining mechanism comprises a water balance cavity used for being balanced with external water, and a power assembly used for discharging water in the water balance cavity is arranged above the water balance cavity. The water balance cavity comprises an inner cavity adjacent to the water level measurer, an outer cavity communicated with external water is arranged outside the inner cavity, a water absorption filter part is arranged in the outer cavity, a middle partition plate is arranged between the inner cavity and the outer cavity, and a connecting through hole is formed in the middle partition plate. By adopting the inner cavity and the outer cavity which are arranged in a matched mode, external water can be filtered through the water absorption filtering piece in the outer cavity and then enters the inner cavity, and therefore the overall stability is guaranteed.

Description

technical field [0001] The present application relates to a paddy field water viewing device and a method for controlling the paddy field water level. Background technique [0002] In the process of rice planting, since rice is a crop with high water requirements, it is more important to monitor the water volume in the paddy field. However, due to the influence of transpiration and precipitation, the water volume in the paddy field is in frequent dynamic changes. Most of the current control methods use scales, water level gauges or even empirical judgments, and the accuracy is poor. There are also some methods of telemetry or remote monitoring, but the monitoring effect is poor, and it cannot accurately feed back the real amount of water that can be used for rice. This makes it very obvious that there are inadequacies. Contents of the invention [0003] In order to solve the above problems, the present application discloses a paddy field water viewing device on the one h...
