Description

Water level control device {APPARATUS FOR CONTROLING WATER LEVEL}

The present invention relates to a water level control device that can control the water level in a reservoir, such as rice paddies.

As is well known, reservoirs, in particular rice fields, can be supplied with water from the surrounding streams, which are divided into several cultivation zones by paddy fields, and in each cultivation zone at the lateral edge of the farm road along the length of the paddy field. Accordingly, an open water supply passage may be provided.

A water supply port may be installed on the sidewall of the water supply passage located in each of the tillage zones, and water flowing along the water supply passage may be supplied from each water supply hole to each tillage zone.

In addition, an open drainage channel is provided between the discussions located on the opposite side of the water supply passage, and a water level regulator may be installed at the drainage opening of the drainage channel located in each tillage zone. By adjusting the height of this level adjuster, it is possible to maintain the water level in each tillage zone at a constant height.

On the other hand, the downstream side of the drainage channel is connected to the drainage channel, and the surplus water or rainwater discharged to the drainage channel flows to the surrounding rivers through the channel.

In the above-described discussion structure, the water flowing along the water supply passage can be sequentially introduced into each tillage zone from the upstream water supply port, and this water is maintained at a constant level by the water level regulator, and at the same time, the surplus water flows into the drainage channel. May be discharged.

As a result, in the conventional paddy fields in which each channel is open, the space of the cultivation zone and the farm path is narrowed by the occupation width of the water supply passage and the drainage passage, so there is a problem in that farmland cannot be efficiently used, and the water supply management of the rice paddy is periodically conducted. There is a problem in that human and material costs are required because it must be done.

The present invention is to provide a water level control device that can be easily discharged to the water when the water level is installed in a reservoir such as rice paddy.

In addition, the present invention is to provide a water level control device that can be easily discharged to the outside through the internal discharge pipe while the internal air is discharged to the outside when a certain level in the closed state inside.

The objects of the embodiments of the present invention are not limited to the above-mentioned objects, and other objects not mentioned can be clearly understood by those skilled in the art from the following description .
