JPH0739384U - Automatic water supply / drainage circulation device for paddy water - Google Patents

Abstract

(57) [Summary] [Object] The present invention relates to an automatic water supply / drainage adjusting device for automatically supplying / draining water 3 for a paddy field 2 and always maintaining an appropriate water level. The water supply / drainage adjusting device of the present invention is for circulating an adjusting device body 6 composed of a drainage port 7 having a drainage valve 8 and a water supply pipe 11 having a discharge port 12, an intake basin body 13 and water 3. It is formed of a circulation pump 15 and a water pipe 14.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic water supply / drainage circulation device for paddy water.

[0002]

[Prior art]

 Recently, in areas where cold damage is likely to occur, such as the Tohoku region, the need for extremely detailed flood control in paddy water has been reconsidered.

On the other hand, as for the water management system for irrigation water, a device relating to an irrigation canal device for taking in water from a paddy field to a sewage field is presented in Japanese Utility Model Laid-Open No. 58-1632.

Further, a water management system having a control means for actuating the water level and temperature measuring means and the water intake means is disclosed in Japanese Patent Application No. 61-149243, but all of them are technical ideas of the present invention. Is completely different from.

[0005]

[Problems to be solved by the device]

 In other words, in the conventional technology, since the running cost is high and maintenance is difficult, it has not spread to general farmers yet, and in actual flood control, the valve installed in the paddy field is opened and closed each time, and The current situation is that the water level is controlled empirically.

As described above, the current flood control work requires a considerable amount of labor, but due to the aging of agricultural managers and a decrease in successors, there is always a shortage of labor and it is extremely detailed. Flood control is impossible.

[0007]

[Means for Solving the Problems]

 Therefore, in order to solve this problem, we devised a circulation device that can automatically supply and drain the water 3 for the paddy field 2.

That is, in the present invention, as shown in FIG. 1 and FIG. 2, the adjusting device main body 6 having both the drainage port 7 having the drainage valve 8 with the water level adjusting spring 9 and the water supply pipe 11 with the discharge port 12 and the water intake By installing the cell body 13 in the water pipe 14 and operating the circulation pump 15 as necessary, water supply and drainage can be automatically controlled alternately.

A water level adjusting balancer 10 may be attached to the drain valve 8 to adjust the water level.

[0010]

[Action]

 The operation of the present invention will be described with reference to FIGS.

The water management of the paddy field 2 is an important work for stabilizing the rice cultivation of the year, and the stable management of the water level is necessary.

Therefore, first, in order to determine the water level of the paddy field 2 as necessary, the repulsive force of the water level adjusting spring 9 of the drain valve 8 of the adjusting device body 6 is appropriately adjusted, or the weight of the balancer 10 is changed. Adjust the water level.

Next, when the circulation pump 15 is operated, the water 3 passes through the water pipe 14 to enter the intake basin body 13, and further from the outlet 12 of the water supply pipe 11 provided in the adjusting device body 6 to the paddy field 2. Water is supplied.

On the other hand, when the water level rises more than necessary, the drainage valve 8 is pushed up while entering the adjusting device body 6 from the drainage port 7 and flowing into the water channel 14 pipe, but when the amount of water is large, the circulation pump 15 is turned on. It can be operated and drained forcibly.

Thus, by adopting the circulation device of the present invention, the water level can be automatically controlled.

[0016]

【Example】

 According to the method of the present invention, the water can be automatically circulated without waste and an appropriate water level can be maintained at all times, so that cold water is rarely replenished, and even during a cold damage year, the temperature is raised to about 2-3 degrees. Can hold

[0017]

[Effect of device]

 As described above, the feature of the present invention is that the water level of the paddy field water can be automatically controlled, which has the advantage of reducing the labor of general farmers, and the water can be constantly circulated, so that the water temperature in the paddy field can be adjusted to an appropriate temperature. Since it can be maintained, it is possible to suppress pests and diseases caused by cold weather, grow healthy rice even in the year of cold weather, and secure a stable yield.
