WATER CHANNEL OPENING/CLOSING DEVICE OF FARM FIELD
To provide a water channel opening/closing device of a farm field in which an installation site of a water gauge unit can be widely selected.SOLUTION: A water channel opening/closing device 3 comprises: a valve body unit 4 which is connected to a water channel forming member 201 forming a water supply channel 2 to a farm field 1; and a water gauge unit 5 which detects that a water level in the farm field 1 reached a predetermined water level. The valve body unit 4 comprises: a body 26 which has a water flow channel 26a communicating with the water supply channel 2 on an inside thereof; and a valve body 27 which opens/closes the water flow channel 26a. A transmission body 13 that transmits detection of a predetermined water level by the water gauge unit 5 to the valve body unit 4, and permits movement from an open position of opening the water flow channel 26a of the valve body 27 to a closing position of closing the water flow channel is provided between the water gauge unit 5 and the valve body unit 4. The valve body unit 4 has a plurality of connection parts 29 capable of connecting the transmission body 13. The valve body 27 moves from the open position to the closing position by permission of the transmission body 13 connected to any connection part 29 out of the plurality of connection parts 29, 29.SELECTED DRAWING: Figure 1
【課題】 水位計ユニットの設置場所を広く選ぶことができる、圃場の水路開閉装置を提供する。【解決手段】 水路開閉装置３は、圃場１への給水路２を形成する水路形成部材２０１に接続される弁体ユニット４と、圃場１内の水位が所定水位になったことを検知する水位計ユニット５とを、備える。弁体ユニット４は、給水路２と通じる流水路２６ａを内側に有する本体２６と、流水路２６ａを開閉する弁体２７とを備える。水位計ユニット５と弁体ユニット４との間に、水位計ユニット５による所定水位の検知を弁体ユニット４に伝達して、弁体２７の流水路２６ａを開放する開位置から閉鎖する閉位置への移動を許可する伝達体１３が設けられる。弁体ユニット４は、伝達体１３を接続可能な接続部２９を複数有する。複数の接続部２９、２９のうちの任意の接続部２９に接続された伝達体１３の許可により、弁体２７が、開位置から閉位置に移動する。【選択図】 図１
