(57) [Summary] [Object] The present invention provides an apparatus for automatically and continuously measuring water level data of a paddy field 10 by applying ultrasonic waves. [Structure] In the device of the present invention, an ultrasonic transmitter / receiver 7 is mounted in a housing 5 filled with sand 6 in an eccentric position so as to prevent noise from entering, and the housing 5 is attached to a paddy field 10
It is buried in the ground and the water level is measured.
Description
【０００１】[0001]
本考案は、水田の水位を測定するための超音波装置に関する。 The present invention relates to an ultrasonic device for measuring the water level in a paddy field.
【０００２】[0002]
最近、水田の治水管理にコンピューターによる自動化技術が開発されつつある が、より精度の高い自動水位計の開発が重要である。 Recently, computerized automation technology has been developed for flood control of paddy fields, but it is important to develop a highly accurate automatic water level gauge.
【０００３】 しかしながら、この種の従来技術は、未だに開発されていないのが現状である 。However, this type of conventional technique has not yet been developed.
【０００４】[0004]
水田用に用いる水位計は、田植え機や整地用のトラクターが移動する際に邪魔 にならないことと、迅速に、かつ連続して水位測定が可能なことが必要である。 The water level gauge used for paddy fields should be unobtrusive when the rice transplanters and tractors for leveling are moving, and be able to measure the water level quickly and continuously.
【０００５】[0005]
そこで、かかる課題を解決するために、超音波を応用した構造が簡単で安価な 水田用自動水位計を開発した。 Therefore, in order to solve this problem, we have developed an automatic water level gauge for paddy fields that uses ultrasonic waves and has a simple structure and is inexpensive.
【０００６】 すなわち、本考案では、地中から水面２に向けて超音波を発信し、その水面２ からの反射波を受信できるように、砂６を充填したハウジング５内の偏位置に超 音波発信・受信器７を取付け、ノイズが出来るだけ軽減するようにしたことと、 田植え機やトラクターの移動に支障がないように地下に埋設したことと、その重 量に耐えられ、かつ埋設位置が片寄らないように、ハウジング５の底面積を２倍 以上にして頑強な構造にしたことと、埋設位置を地盤表面から３０ｃｍ以上にし て、負荷の影響をなくしたこと等を考慮した構造にしている。That is, in the present invention, ultrasonic waves are transmitted from the ground toward the water surface 2 and ultrasonic waves are eccentrically located in the housing 5 filled with sand 6 so that the reflected waves from the water surface 2 can be received. The transmitter / receiver 7 was attached to reduce noise as much as possible, and it was buried underground so as not to hinder the movement of rice transplanters and tractors. The structure is designed with consideration given to the fact that the bottom area of the housing 5 has been doubled or more to make it robust, and the buried position is 30 cm or more from the ground surface so as to eliminate the influence of load, etc. .
【０００７】[0007]
【作用】 本考案の作用については、図１と図２を参照しながら説明する。[Operation] The operation of the present invention will be described with reference to FIGS. 1 and 2.
【０００８】 まず、砂６を充満したハウジング５に超音波発信・受信器７を設置し、このハ ウジング５を水田の地下３０ｃｍ以上に水平に埋設する。First, an ultrasonic transmitter / receiver 7 is installed in a housing 5 filled with sand 6, and the housing 5 is horizontally buried at a depth of 30 cm or more underground in a paddy field.
【０００９】 次に、超音波発信・受信器７に電源用コネクター８およびデーター測定、デー ター処理解析用装置のコネクター９を接続した後、各測定機器の電源を入れ機器 の調整を行い、水位測定を開始する。Next, after connecting the power source connector 8 and the connector 9 for the data measurement and data processing / analysis device to the ultrasonic transmitter / receiver 7, the power of each measuring device is turned on and the device is adjusted to adjust the water level. Start the measurement.
【００１０】 本考案の特徴は、水田１０の地下に超音波発信・受信器７を埋設するため、常 に適当な水分が発信・受信器７に充満していることが重要であり、従って、ハウ ジング５内に砂６を充填して、地表３の水面２と常に接触するよう工夫している 。The feature of the present invention is that the ultrasonic transmitter / receiver 7 is buried underground in the paddy field 10. Therefore, it is important that the transmitter / receiver 7 is always filled with appropriate water. The housing 5 is filled with sand 6 so that it is always in contact with the water surface 2 on the surface 3.
【００１１】[0011]
本考案の自動水位計を使用した場合、コンピューターのデーター処理解析装置 に接続すると、常に水田の水位データーを自動的かつ連続的に収集記録すること ができる。 When the automatic water level gauge of the present invention is used, it is possible to collect and record the water level data of the paddy field automatically and continuously by connecting to the data processing and analysis device of the computer.
【００１２】[0012]
このように、本考案の水田用自動水位計は、構造が簡単であり、迅速にかつ高 い精度で連続的に水位を測定できるので、省力化の効果は大きい。 As described above, the automatic water level gauge for paddy fields of the present invention has a simple structure and can continuously and rapidly measure the water level with high accuracy, so that the labor saving effect is great.
