A paddy field automatic water supply and drainage device

Abstract

The invention discloses an automatic water supply and drainage device for a paddy field. The device includes a water storage tank on one side of paddy fields. Protective boxes are arranged between thepaddy fields and the water storage tank. The inner bottom of each protective box are fixedly connected with a U-shaped pipe, and each U-shaped pipe is formed by making a small vertical part, a horizontal part and a large vertical part connected in sequence. The device has the advantages that through change of buoyancy of a float ball, the float ball, a synchronous rod and a connecting rod move vertically, and a driving rod, a small piston, the U-shaped pipes, a large piston and a driven rod are used for achieve the transformation of force and displacement, starting of a throttle gate and communication of a water supply circuit and a drainage circuit. A two-way water pump is used for achieving water supply and drainage in the water depth range, the whole process does not need manual measurement, observation and decision-making, labor and time are saved, large-scale paddy field agriculture can be managed well, and the agricultural modernization need of the paddy field is met.

Description

technical field [0001] The invention relates to the technical field of water supply and drainage equipment, in particular to an automatic water supply and drainage device for paddy fields. Background technique [0002] According to the water source, paddy fields are divided into two categories: irrigated paddy fields and Wangtian fields. Among them, irrigated paddy field refers to the arable land that has water source guarantee and irrigation facilities, can be irrigated normally in normal years, and is used for planting aquatic crops. In the paddy field planting industry, the depth of water in the paddy field must be within a certain range to ensure the water demand of aquatic crops in different periods. The traditional technology generally uses a measuring stick to measure and insert it into the bottom of the paddy field, observe the value of the measuring stick with the naked eye, and start the pump to clean the paddy field. The way of water supply and drainage is manage...

Problems solved by technology

In the paddy field planting industry, the depth of water in the paddy field must be within a certain range to ensure the water demand of aquatic crops in different periods. The traditional technology generally uses a measuring stick to measure and insert it into the bottom of the paddy field, observe the value of the measuring stick with the naked eye, and start the pump to clean the paddy field. The way of water supply and drainage is managed. The managers must measure, observe, and water supply and drainage at intervals to ensure that the water depth of the paddy fields is kept within a certain range at all times. It is more manpower and time-consuming. When facing large-scale paddy fields, this method It is obviously not feasible and cannot meet the needs of modern agricultural industrialization, so it needs to be improved urgently
