Description

Paddy water level notification device {WATER-LEVEL CONTROL NOTIFICATION DEVICE OF PADDY FIELD}

The present invention relates to a water level notification device for paddy fields, and more specifically, measures the water level in one or more paddy fields, and when it is determined that the water level is low, notifies the manager so that the paddy can be managed stably It relates to a paddy water level notification device.

Paddy fields are farmland filled with water and grown crops, and are mainly used for cultivating crops such as rice. In a general rice paddy field, a ridge is made on a flat floor with soil around the perimeter, and agricultural water is filled inside. In order to enter and exit the agricultural water, a water intake tank is placed where the water flows in, and a drain tank is placed where the water flows out. makes

When cultivating rice, which is mainly grown in paddy fields, maintain the water depth of 2 to 10 cm for agricultural water, and adjust the water level when it is necessary to keep warm during the growing period or to supply oxygen to the roots and suppress unnecessary tillering.

Controlling the water level for agricultural use is one of the most important factors for rice cultivation in paddy fields. Although the goal of water level control for paddy fields is to provide water at an even height to all areas of the paddy field, it is experiencing practical difficulties.

1 is a view schematically showing changes in agricultural water in a general paddy field (P). Hereinafter, the water level control problem of agricultural water currently occurring in paddy fields will be described with reference to FIG. 1 .

As described above, it is important to flatten the bottom of the general paddy field (P), but in reality, it is very difficult to till the paddy field, which is a soil bottom close to mud, in a flat state. Therefore, no matter how manpower or machine is used, it is curved like the paddy field G of FIG. 1 , and sometimes a protruding hill GT occurs.

When the agricultural water (W) is filled on the paddy floor (G) as described above, at first, as in A of FIG. ) is not revealed.

However, over time, agricultural water (W) naturally decreases as it evaporates into the atmosphere or seeps into the ground. Therefore, as long as agricultural water is not added or rain does not come, the level of agricultural water as in A of FIG. 1 is lowered as in B of FIG. 1 , and thus the mound GT is exposed outside the water surface.

When the mound (GT) is exposed outside the water surface as in FIG. 1B, a problem occurs in crop cultivation in the paddy field (P). First, the crops planted on the exposed mound (GT) do not receive sufficient moisture. They die or fail to grow properly.

And on the hill (GT) exposed as described above, not only the target crop does not grow well, but also weeds, which are not the target crop, grow abundantly, affecting the growth of not only the crop on the hill (GT) but also the surrounding crops. There was a problem in that the unnecessary amount of work of managers and workers was increased.

Accordingly, unnecessary work in which the manager must continuously check the rice fields in order to maintain the level of the rice fields and prevent the mounds GT from being exposed has also been added. Therefore, even if the manager does not directly check the level of paddy fields, it is required to develop a technology that can confirm the level of the rice paddy he is currently managing and whether the level of the paddy field has not fallen below the dangerous level.

A device for checking and adjusting the level of discussion as described above is disclosed in Korean Patent Publication No. 10-2019-0033735. The above-mentioned published patent uses a water level detecting post in the form of an iron pile including a water level sensor and a solar cell in order to check the water level of the paddy field, which is partially similar to the water level sensor used in the present invention.

However, the water level sensing pole of the disclosed patent is a configuration in which it is questionable whether its operation is actually effective, and the risk of failure and damage is high.

To explain this in more detail, first of all, since the water level sensing post of the disclosed patent further includes a camera and the like, it is different from the present invention in its configuration and is more sensitive to failure.

In addition, the support plate for fixing the support to the ground does not exist for the support of the published patent, so the base of the support is weakened due to liquefaction of the paddy ground, etc. Therefore, there is a high risk of falling of the holding, and if the holding is overturned, the possibility of damage to the electrical components such as solar cells and storage batteries that are sensitive to moisture increases, which can cause economic problems.

In addition, the disclosed patent has differences in the configuration of the water level notification device provided by the present invention, and thus the present invention is judged to have acquired significant inventive step in comparison with the disclosed patent.

In addition, Patent Registration No. 10-1893822 discloses an automated water management system in which the freshwater level of paddy fields is adjusted according to the growing season of rice. It is judged that the registered patent is also different from the present invention in its configuration and operation method.

In addition, Japanese Patent Laid-Open Publication No. 2014-099124 discloses a disaster prevention information delivery system applied to agricultural waterways, ponds, agricultural dams, reservoirs, rivers, and the like. water level alarm; communication department; interval data; and a server including a control unit and the like are provided, but the installation method and equipment are not disclosed.

And in Patent Publication No. 10-2008-0000707, the main body; water level sensor; and a data locker that is data compatible with a general PC is disclosed, and the device is composed of a cover, a body, a through hole, a support plate, a leveler, etc., but the configuration is not It is an invention whose implementation is questionable due to its complexity.

In order to solve the problems of the prior art, the present invention can transmit information related to the level of discussion in real time when the manager's terminal requests it, and also notify the manager when the level of discussion falls below a set level, An object of the present invention is to provide a paddy water level notification device that is easy to install and maintain.
