Paddy field irrigation device capable of controlling irrigation level

Abstract

The invention provides a paddy field irrigation device capable of controlling irrigation level. The device comprises a water level control pipe, a mounting frame and a water level sensing assembly, wherein the water level control pipe is rotationally connected with the mounting frame, and the water level sensing assembly is connected to the water level control pipe through a connecting block and the water level control pipe comprises a water inlet pipe, a water outlet pipe and a closed pipe, and one end port of the closed pipe is closed. One end of the closed pipe is closed, water can flow into the closed pipe through the water outlet pipe, so that weight of the water in the closed pipe is gradually changed, irrigation can be stopped only when the water level in the paddy field reaches preset irrigation water level, and the irrigation water level can be accurately controlled; distances between adjacent openings in annular bosses of the water inlet pipe are unequal, the openings are inone-to-one correspondence with bosses in an extension pipe on a tetrahedral frame, therefore, the water level control pipe and the tetrahedral frame can only be connected and separated in a unique position on the whole circumference, and the stability of the device is improved.

Description

technical field [0001] The invention relates to the field of paddy field irrigation, in particular to a paddy field irrigation device capable of controlling irrigation water level. Background technique [0002] In the field of rice planting, it is necessary to build a ridge around the field, and to irrigate in the field, a control device for drainage and irrigation is required. The usual drainage and irrigation device is a gate valve that moves up and down, and is placed at the opening of the ridge. When drainage or irrigation is required , Lift the gate of the valve, the drainage or irrigation port gradually becomes larger from bottom to top, water first enters or discharges from the bottom of the valve, and the valve needs to be closed manually after reaching the required amount, otherwise the water will enter or discharge excessively. In the process, each field needs to be guarded, which requires a large amount of labor and is not easy to control. A rotary tube type drai...

[0002] In the field of rice planting, it is necessary to build a ridge around the field, and to irrigate in the field, a control device for drainage and irrigation is required. The usual drainage and irrigation device is a gate valve that moves up and down, and is placed at the opening of the ridge. When drainage or irrigation is required , Lift the gate of the valve, the drainage or irrigation port gradually becomes larger from bottom to top, water first enters or discharges from the bottom of the valve, and the valve needs to be closed manually after reaching the required amount, otherwise the water will enter or discharge excessively. In the process, each field needs to be supervised, which requires a large amount of labor and is not easy to control

A rotary tube type drainage and irrigation device, although it can control the water level in the field, it can only control the drainage, and can control the discharge of excess water in the field, but it cannot automatically close the gate valve when the water level reaches the required water level.

Manual operation is required to stop irrigation and close the gate valve
