Description

Water level control system in paddy field {WATER-LEVEL CONTROL SYSTEM OF PADDY FIELD}

The present invention relates to a water level control system in a paddy field, and more particularly, measures the water level in one or more paddy fields, and when the water level falls below or exceeds a set height, it is notified to the manager, and And it relates to a paddy water level control system for stably managing the paddy field by controlling the opening and closing of the drainage channel to control agricultural water.

Paddy field is a farmland filled with water and cultivated crops, and is mainly installed to grow crops such as rice. In general paddy fields, the circumference is made of soil with soil, and agricultural water is filled in. For the access of agricultural water, a water intake reservoir is placed where the water flows in, and a drainage reservoir is placed where the water flows. Make

When cultivating rice grown mainly in paddy fields, keep the water depth of agricultural water at about 2~10cm, and during the growing period, it is necessary to keep warm, supply oxygen to the roots, suppress unnecessary dust, or increase the water level to suppress the growth of weeds. It also adjusts.

This level control of agricultural water is one of the most important factors for rice cultivation in paddy fields, and it is aimed at providing water to all areas of the paddy at an even height, but it is experiencing practical difficulties.

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

As described above, it is important to compact the bottom of the general paddy field P, but in reality, it is very difficult to keep the paddy bottom, which is a soil floor close to mud, in a flat state. Therefore, no matter how much manpower or machinery is used to cultivate the paddy field, it is bent as in the paddy field G of FIG. 1, and in some cases, a protruding mound (GT) occurs.

When the agricultural water (W) is filled on the paddy field (G) as described above, the agricultural water (W) is initially filled in the paddy field (P) as desired by the manager as shown in A of FIG. 1, so that the mound (GT ) Does not appear.

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

As shown in Fig. 1B, when the mound (GT) is exposed to the outside of the water surface, a problem occurs in cultivation of crops in the paddy field (P). First, the crops planted on the exposed mound (GT) do not receive sufficient moisture and dry out. It either dies or does not grow properly.

In addition, not only does the target crop not grow well on the mound (GT) exposed as above, and weeds other than the target crop grow abundantly, affecting the growth of not only the crop above the mound (GT) but also the surrounding crops. There has been a problem of increasing the unnecessary amount of work for managers and workers.

Accordingly, in order to maintain the level of the rice paddies and prevent the mound (GT) from being exposed, unnecessary work was also added, requiring the manager to continuously check the rice fields. Therefore, even if the manager does not directly check the level of the rice field, it is required to develop a technology that can confirm how much the level of the rice field is currently being managed and whether the level of the rice field has not fallen below the risk level.

A device for checking and adjusting the water level in the field is disclosed in Korean Patent Application Publication No. 10-2019-0033735. The above disclosed patent uses a water level detection pillar including a water level sensor and a solar cell for checking the water level in the rice field, which is partially similar to the water level detector used in the present invention.

However, the water level detection pillar of the above patent is a configuration in which it is questionable whether the operation is substantially effective, and there is a high risk of failure and damage.

To describe this in more detail, first of all, the water level detection pillar of the disclosed patent further includes a configuration such as a camera, and thus differs from the present invention in its configuration and is more sensitive to failure.

In addition, since the support plate for fixing the pillar to the ground does not exist in the pillar of the above patent, there is no structure that can support it when the foundation of the pillar is weakened due to liquefaction of the field, etc. Therefore, there is a high risk of the pillars falling, and if the pillars are collapsed, the possibility of damage to electrical components such as solar cells and storage batteries that are sensitive to moisture increases, resulting in economic problems.

In addition, since the disclosed patent differs in the configuration and operation method of the water level control systems provided by the present invention, it is determined that the present invention has acquired significant advances compared to the disclosed patent.

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

In order to solve the problems of the prior art, the present invention transmits the discussion water level information in real time when the manager's terminal requests it, and can notify the manager when the discussion water level falls below the set water level. It is an object to provide a control system.

The hole 112 performs two roles, one of which, after the body 110 is inserted into the paddy land filled with agricultural water, serves to equally match the internal and external pressures of the body 110 . As described above, the water level alerter 100 must perform a function of measuring the level of agricultural water, and when the body 110 constituting the water level alerter 100 is inserted into the ground, the interior and exterior are completely If it is disconnected, there is a problem that the pressure difference occurs inside and outside, so that the level of agricultural water inside and outside fluctuates, and the level of agricultural water cannot be measured effectively. Accordingly, at least one of the holes 112 must be formed on the side of the body 110 even for the aforementioned pressure control.

And another role that the hole 112 can perform is to allow agricultural water to communicate with the inside and outside of the body 110 through the hole 112, so that the water level alerter 100 It is to make more accurate agricultural water level measurements. If the agricultural water inside the body 110 and the agricultural water outside the body 110 cannot communicate with each other and are disconnected, there is an environmental difference between the inside and the outside of the body 110, for example, weather changes due to rainfall or the sun. This is because a difference may occur between the level of the agricultural water inside the body 110 and the level of the outside of the agricultural water due to the difference in evaporation due to the difference in the amount of insolation. Therefore, preferably, as shown in FIGS. 2 and 3, the hole 112 is formed at least two (112a, 112b), and is disposed at the top (112a) and the bottom (112b), the top hole (112a) agricultural water It is preferable to perform the function of adjusting the pressure difference inside and outside the body 110 by not being immersed in the body 110, and the lower hole 112b to be immersed in agricultural water to perform the communication function of the agricultural water.
