Description

本発明は、水田における排水量の調節を行うための水田排水量調整器具に関する。 The present invention relates to a paddy field drainage volume adjustment device for adjusting the amount of drainage in paddy fields.

近年、地球温暖化に伴う降雨量の増加による水路や河川等の氾濫を防止するため、水田からの排水量を制限し、一時的に雨水を水田に貯留させながら徐々に下流へ排水する、「田んぼダム」の取組が全国的に推進されている。
そのため、従来、下記非特許文献1にあるような調整器具が存在している。
In recent years, in order to prevent the flooding of waterways and rivers caused by increased rainfall due to global warming, efforts to build "rice paddy dams" have been promoted nationwide. These dams limit the amount of water discharged from rice paddies and temporarily store rainwater in the paddy fields before gradually discharging it downstream.
For this reason, there have conventionally been adjustment tools such as those described in Non-Patent Document 1 below.

非特許文献1は、田んぼダムの取り組みのためにフリードレーン式の排水口(円筒状の管を水田の上向きに開口した排水口に取り付け、これを上下に動かすことにより水田の水位調節を行う排水口の方式。)に取り付ける、漏斗の形状により排水量を制限させる水田排水量調整器具である。 Non-patent document 1 describes a paddy field drainage volume adjustment device that is attached to a free-drain type drainage outlet (a type of drainage outlet in which a cylindrical pipe is attached to an upward-opening drainage outlet of a paddy field, and the water level of the paddy field is adjusted by moving the pipe up and down) for the purpose of dealing with paddy field dams, and limits the amount of drainage by using the shape of a funnel.

「田んぼダム」の手引き、農林水産省、P-41,42"Rice Field Dam" Handbook, Ministry of Agriculture, Forestry and Fisheries, P-41, 42

しかしながら、フリードレーン式の排水口(フリードレーン管と呼ばれる円筒状の管を水田の排水口に取り付け、これを上下に動かすことにより水田の水位調節を行う排水口の方式。)において、従来の調整器具を設置する場合、フリードレーン管に付属した取っ手取り付け部の支障や、経年に伴う管形状の歪みにより、そのまま設置できないという課題があった。 However, when installing conventional adjustment devices in a free-drain type drain outlet (a type of drain outlet in which a cylindrical pipe called a free-drain pipe is attached to the drain outlet of a paddy field and the water level in the paddy field is adjusted by moving it up and down), there were issues with not being able to install it as it was due to interference with the handle attachment part attached to the free-drain pipe and distortion of the pipe shape over time.

本発明は、このような課題に対し、フリードレーン式排水口におけるフリードレーン管の取っ手取り付け部における支障や、経年に伴う管形状の歪みに対して対応できるほか、一般的な円形で上向きに開口した排水口全般においても、後付けでそのまま設置し水田の排水量を調整できる、汎用性の高い水田排水量調整器具を提供する。 The present invention addresses these issues by providing a highly versatile paddy field drainage volume adjustment device that can address problems such as problems with the handle attachment part of the free drain pipe in a free drain type drain outlet and distortion of the pipe shape that occurs over time, and can also be installed as a retrofit on any typical circular drain outlet that opens upwards to adjust the drainage volume of the paddy field.

上記課題を解決するために、本発明は以下の手段を提供する。
水田の上向きに開口した排水口に取り付けた場合に、前記排水口に2箇所以上の載荷部を持つとともに、排水通過口を形成する第1立体形成部を備えることで、排水量の調整を行うことができることを特徴とする。なお、前記排水通過口の面積は、一般的な田んぼダムの取り組みのための水田排水量調整器具で採用されている直径5cmの円の面積と同等程度が好ましい。
In order to solve the above problems, the present invention provides the following means.
When attached to a drainage outlet that opens upward in a paddy field, the drainage outlet has two or more loading parts and is equipped with a first three-dimensional forming part that forms a drainage passage, so that the drainage volume can be adjusted. Note that the area of the drainage passage is preferably approximately the same as the area of a circle with a diameter of 5 cm that is used in paddy field drainage volume adjustment devices for general rice paddy dam construction.

前記排水口に取り付けた場合に、前記排水通過口が2箇所以上形成されることを特徴とする。 When attached to the drain outlet, the drain passage opening is formed in two or more places.

前記排水口に取り付けた場合に、前記第1立体形成部の端部において、前記排水通過口が2箇所以上形成されることで、フリードレーン管の取っ手取り付け部の支障を防ぐことを特徴とする。 When attached to the drain, the drain passage openings are formed in two or more places at the end of the first three-dimensional forming part, which prevents interference with the handle attachment part of the free drain pipe.

前記排水口に取り付けた場合に、鉛直下方向に張り出し、前記排水口の内側に位置する第2立体形成部を備えることで、脱落防止の効果を発揮することを特徴とする。 When attached to the drain, it is characterized by having a second three-dimensional formed part that protrudes vertically downward and is located inside the drain, thereby preventing it from falling off.

水よりも比重が大きい材質(例えば、セメント系、樹脂系、ゴム、金属等)であることで水田の水位が高くなった際に浮力により浮き上がらないことを特徴とする。 The material has a higher specific gravity than water (e.g., cement-based, resin-based, rubber, metal, etc.), so it does not float up due to buoyancy when the water level in the rice paddy rises.

本発明によれば、フリードレーン式排水口におけるフリードレーン管の取っ手取り付け部における支障や、経年に伴う管形状の歪みに対して対応できるほか、一般的な円形で上向きに開口した排水口全般においても、後付けでそのまま設置し水田の排水量を調整できる、汎用性の高い水田排水量調整器具を提供することが可能になる。 This invention makes it possible to provide a highly versatile paddy field drainage volume adjustment device that can address problems with the handle attachment part of the free drain pipe in a free drain type drain outlet and distortion of the pipe shape that occurs over time, as well as be able to adjust the drainage volume of paddy fields by simply installing it on any typical circular drain outlet that opens upward.
