specific Embodiment approach 1

[0008] Embodiment 1: The farmland irrigation automatic water control system described in this embodiment includes a water level monitor 1 and a water supply device. 1-3, the lower inserted pyramid 1-1 is a pyramid, and the lower inserted pyramid 1-1 is marked with a horizon scale line, and the lower water level gauge 1-2 and the upper water level gauge 1-3 are fixedly connected to the lower inserted pyramid The upper end of the pyramid 1-1, the lower water level gauge 1-2 and the upper water level gauge 1-3 are all hollow cylinders, and the cylinders are marked with scales. In the cavity of the lower water level gauge 1-2 A lower water level float switch 1-4 is fixed, and the signal output end of the lower water level float switch 1-4 is connected to the opening control signal input end of the water supply device; an upper water level float switch 1 is fixed in the cavity of the upper water level gauge 1-3 -5, the signal output end of the upper water level float switch 1-5 is ...

specific Embodiment approach 2

[0009] Specific embodiment two: the difference between this embodiment and the farmland irrigation automatic water control system described in embodiment two is that the water supply device is composed of a motorized well and a motorized well water pump motor 6, and the opening and closing control signal input terminals of the motorized well water pump motor 6 are water supply Device on and off control signal input. Other components and connections are the same as those in Embodiment 1.

[0010] The reverse water valve should be installed on the water pump of the machine well to prevent the water level of the well from sinking and ensure that the water pump can pump water normally.

specific Embodiment approach 3

[0011] Specific embodiment three: this embodiment is to further limit the water supply device in the farmland irrigation automatic water control system described in specific embodiment one. In this embodiment, the water supply device is composed of a water control valve 2 and a water inlet conduit 3. The water valve 2 is fixedly connected to the water inlet end of the water inlet conduit 3, and the opening and closing control signal input end of the water control valve 2 is the opening and closing control signal input end of the water supply device.

[0012] When the automatic water control system for farmland irrigation described in this embodiment is used to supply water to paddy fields with canals, see figure 1 and 2 As shown, the water level monitor 1 is set in a paddy field close to the water inlet conduit 3 and the water flow fluctuation is small, and the lower inserted pyramid 1-1 is vertically inserted into the paddy field soil, so that the horizon scale line is flush ...

Abstract

An automatic water control system for field irrigation relates to automatic field water control and solves the problem that difficulty of effective precise water level control in field water supply by manual ditching affects seedling growth, wastes water and increases labor cost. The automatic water control system comprises a water level monitor and a water supply device. The water level monitor comprises a lower pyramidal insert, a lower water level gauge and an upper water level gauge, wherein the lower pyramidal insert is pyramidal, both the lower water level gauge and the upper water level gauge are fixedly connected to the upper end of the lower pyramidal insert, both the lower water level gauge and the upper water level gauge are hollow tubes which are graduated, a lower water level float switch is fixed inside a cavity of the lower water level gauge, a signal output end of the lower water level float switch is connected with an activating control signal input end of the water supply device, a signal output end of an upper water level float switch is fixed inside a cavity of the upper water level gauge, a signal output end of the upper water level float switch is connected with a switch-off control signal input end of the water supply device. The automatic water control system is used for automatic field water control.

Description

technical field [0001] The invention relates to automatic water control in farmland. Background technique [0002] Rice has always been one of the most important food crops for people, and its cultivation technology has a history of five or six thousand years. In recent years, the degree of mechanization of rice planting has been greatly developed, but the water level control, water control and water management in each growth period of rice seedlings are still completed by manual labor. Due to the extensiveness of manual operation (manually digging canals for water supply), it is difficult to effectively and precisely control the water level height, which not only affects the growth of seedlings, but also wastes water resources and increases labor costs. Contents of the invention [0003] The purpose of the present invention is to solve the problem that it is difficult to accurately control the water level due to manual digging of canals in the farmland, which not only af...
