Description

本発明は、農業用水路又は揚水場の水路等の各種の水路に配置された水門開閉器に取付けることにより、水門の開閉の電動化及び遠隔操作を実現する水門開閉器用駆動装置に関する。 The present invention relates to a sluice gate drive device that realizes electrification and remote control of opening and closing of sluice gates by being attached to sluice gates disposed in various waterways such as agricultural waterways or waterways of water pumping stations.

従来、比較的小型の水門開閉器では、手動ハンドルで駆動軸を回転させることにより、水門の開閉を行っている。
しかしながら、人力で水門を開閉するには、十分な力と時間を必要とし、極めて作業性が悪いという問題があった。
そこで、本出願人は、特許文献１に示すように、電動工具を動力源として、既存の水門開閉器に付設される補助駆動装置を出願し、特許された。この特許文献１の水門開閉器の補助駆動装置においては、動力源となる電動工具が、ギアボックスに対して取付け取外しできるため、電動工具を収納する部屋を設ける必要がなく、装置全体の小型化が図られ、一台の電動工具で、複数の水門開閉器を順次、駆動することも可能であった。また、電動工具に取付けた水平ロッドが、ギアボックスの蓋材に形成された貫通孔に嵌入されることによって、電動工具の駆動時に発生する反回転力が作業者に伝わることが防止され、作業性の改善が図られた。 Conventionally, in relatively small water gate switches, the water gates are opened and closed by rotating a drive shaft using a manual handle.
However, opening and closing the flood gates manually requires sufficient force and time, resulting in extremely poor workability.
Therefore, as shown in Patent Document 1, the present applicant filed an application for an auxiliary drive device attached to an existing water gate switch using an electric tool as a power source, and was granted a patent. In the auxiliary drive device for a water gate switch disclosed in Patent Document 1, the power tool serving as the power source can be attached to and removed from the gearbox, so there is no need to provide a room to store the power tool, and the overall device can be made smaller. It was also possible to drive multiple floodgates in sequence with a single power tool. In addition, by fitting the horizontal rod attached to the power tool into the through hole formed in the lid of the gearbox, the counter-rotational force generated when driving the power tool is prevented from being transmitted to the operator, and the Improvements were made in sexual performance.

続いて、添付した図面を参照しながら、本発明を具体化した実施の形態について説明する。
図１に示す本発明の一実施の形態に係る水門開閉器用駆動装置１０は、手動ハンドルが取付け可能な操作軸１１を備え、操作軸１１の正逆回転により水門（図示せず）を開閉する水門開閉器１２に取付けられて、水門の開閉の電動化及び遠隔操作を実現するものである。
水門開閉器用駆動装置１０は、水門開閉器１２に取付けられる駆動部１３と、遠隔から駆動部１３を操作するための制御信号を送信する遠隔コントローラ１４と、水門開閉器１２（又は駆動部１３）の近傍に設置され、遠隔コントローラ１４から送信される制御信号を受信して駆動部１３の動作を制御する制御部１５とを有している。そして、駆動部１３は、図１～図３に示すように、電動モータ１７と、一側（図１、図２では左側）が電動モータ１７に連結されたモータ用入力軸１８及び一側が操作軸１１に連結される直付け用出力軸１９を有し電動モータ１７の回転を操作軸１１に伝達する回転伝達機構２０を備えている。 Next, embodiments embodying the present invention will be described with reference to the attached drawings.
A flood gate switch drive device 10 according to an embodiment of the present invention shown in FIG. 1 includes an operating shaft 11 to which a manual handle can be attached, and opens and closes a water gate (not shown) by rotating the operating shaft 11 in forward and reverse directions. It is attached to the water gate switch 12 to realize motorized opening and closing of the water gate and remote control.
The flood gate switch drive device 10 includes a drive unit 13 attached to the flood gate switch 12, a remote controller 14 that transmits a control signal for remotely operating the drive unit 13, and a drive unit 13 for the flood gate switch 12 (or drive unit 13). The control unit 15 is installed near the remote controller 14 and receives a control signal transmitted from the remote controller 14 to control the operation of the drive unit 13 . As shown in FIGS. 1 to 3, the drive unit 13 includes an electric motor 17, a motor input shaft 18 connected to the electric motor 17 on one side (the left side in FIGS. 1 and 2), and an input shaft 18 on one side that is operated. A rotation transmission mechanism 20 is provided, which has a direct-mount output shaft 19 connected to the shaft 11 and transmits the rotation of the electric motor 17 to the operating shaft 11.

回転伝達機構２０は、図２、図５に示すように、モータ用入力軸１８の他側に取付けられたクラッチ２２と、クラッチ２２を介してモータ用入力軸１８の他側に連結される外部入力軸２３と、外部入力軸２３に取付けられた第１のギア２４と、直付け用出力軸１９に取付けられ第１のギア２４に仲介ギア機構部２５を介して連結された第２のギア２６を備えている。そして、直付け用出力軸１９の他側には、手動ハンドル２８が取付け可能なハンドル取付け部２９が設けられている。ここで、仲介ギア機構部２５は、仲介回転軸３１と、仲介回転軸３１に取付けられ第１のギア２４に噛合する第３のギア３２と、仲介回転軸３１に取付けられ第２のギア２６に噛合する第４のギア３３を備えている。 As shown in FIGS. 2 and 5, the rotation transmission mechanism 20 includes a clutch 22 attached to the other side of the motor input shaft 18, and an external An input shaft 23, a first gear 24 attached to the external input shaft 23, and a second gear attached to the output shaft 19 for direct attachment and connected to the first gear 24 via an intermediary gear mechanism section 25. It is equipped with 26. A handle attachment portion 29 to which a manual handle 28 can be attached is provided on the other side of the output shaft 19 for direct attachment. Here, the intermediate gear mechanism section 25 includes an intermediate rotating shaft 31, a third gear 32 that is attached to the intermediate rotating shaft 31 and meshes with the first gear 24, and a second gear 26 that is attached to the intermediate rotating shaft 31 and meshes with the first gear 24. The fourth gear 33 meshes with the fourth gear 33.

この回転伝達機構２０は、電動モータ１７による駆動時にのみ、モータ用入力軸１８の回転（正転又は逆転）をクラッチ２２により外部入力軸２３に伝達し、直付け用出力軸１９を連動させて操作軸１１を回転させ、手動ハンドル２８による駆動時には、操作軸１１を回転させる直付け用出力軸１９の回転に連動して回転する外部入力軸２３の回転をモータ用入力軸１８に伝達させないようになっている。つまり、モータ用入力軸１８と外部入力軸２３の間にクラッチ２２が設けられることにより、通常は、モータ用入力軸１８と外部入力軸２３の間では回転が伝達されない状態となっており、手動ハンドル２８で直付け用出力軸１９を回転させても、その回転は操作軸１１と外部入力軸２３のみに伝達されるので、モータ用入力軸１８（電動モータ１７）で回転が妨げられることはない。そして、電動モータ１７でモータ用入力軸１８を回転させる際には、クラッチ２２が動作してモータ用入力軸１８の回転を外部入力軸２３に伝達し、その回転をさらに直付け用出力軸１９に伝達することができる。従って、必要に応じて、電動モータ１７による駆動と、手動ハンドル２８による駆動を選択する（切替える）ことができる。 This rotation transmission mechanism 20 transmits the rotation (normal rotation or reverse rotation) of the motor input shaft 18 to the external input shaft 23 using the clutch 22 only when driven by the electric motor 17, and interlocks the direct-mounted output shaft 19. When the operating shaft 11 is rotated and driven by the manual handle 28, the rotation of the external input shaft 23, which rotates in conjunction with the rotation of the direct-mounted output shaft 19 that rotates the operating shaft 11, is prevented from being transmitted to the motor input shaft 18. It has become. In other words, since the clutch 22 is provided between the motor input shaft 18 and the external input shaft 23, rotation is normally not transmitted between the motor input shaft 18 and the external input shaft 23, and the manual Even if the direct-mount output shaft 19 is rotated with the handle 28, the rotation is transmitted only to the operating shaft 11 and the external input shaft 23, so the rotation is not hindered by the motor input shaft 18 (electric motor 17). do not have. When the electric motor 17 rotates the motor input shaft 18, the clutch 22 operates to transmit the rotation of the motor input shaft 18 to the external input shaft 23, and the rotation is further transmitted to the direct-mounted output shaft 19. can be transmitted to. Therefore, driving by the electric motor 17 and driving by the manual handle 28 can be selected (switched) as necessary.

また、図２～図４に示すように、電動工具３５のチャック３６には、六角柱状の連結具３７が取付けられており、回転伝達機構２０は、外部入力軸２３を貫通する六角孔状の工具連結部３８を有している。これにより、外部入力軸２３の他側で、工具連結部３８に対して、連結具３７を着脱可能に装着することができ、電動モータ１７による駆動と、手動ハンドル２８による駆動に加え、電動工具３５による駆動を選択することができる。なお、本実施の形態では、外部入力軸２３を貫通するように六角孔状の工具連結部３８を形成したが、工具連結部は、外部入力軸の他側で連結具を着脱可能に保持（固定）できるものであればよいので、六角孔（貫通孔）の代わりに、工具連結部として、外部入力軸の他側に断面六角形の凹部を形成してもよい。また、連結具と工具連結部は、雄型（凸部）と雌型（凹部）を互いに連結して回転を伝達できるものであればよく、その形状及び組合せは、適宜、選択することができる。例えば、雄型（凸部）と雌型（凹部）は、それぞれ六角形以外の多角形状に形成してもよいし、連結具を雌型（凹部）とし、工具連結部を雄型（凸部）としてもよい。なお、先に説明したように、モータ用入力軸１８と外部入力軸２３の間にクラッチ２２が設けられることにより、通常は、モータ用入力軸１８と外部入力軸２３の間では回転が伝達されない状態となっているので、電動工具３５による駆動時に、外部入力軸２３の回転をモータ用入力軸１８に伝達することなく直付け用出力軸１９に伝達して操作軸１１を回転させ、水門を開閉することができる。ここで、駆動部１３は、回転伝達機構２０が収容されるケーシング４０と、ケーシング４０に取付けられて電動モータ１７を覆うモータカバー４１を有している。そして、外部入力軸２３の他側は第１の軸受４２を介してケーシング４０に回転可能に保持され、仲介回転軸３１の一側及び他側はそれぞれ第２、第３の軸受４３、４４を介してケーシング４０に回転可能に保持され、直付け用出力軸１９の一側及び他側はそれぞれ第４、第５の軸受４５、４６を介してケーシング４０に回転可能に保持されている。第１～第５の軸受４２～４６としては、ベアリングが好適に用いられる。 Further, as shown in FIGS. 2 to 4, a hexagonal column-shaped connector 37 is attached to the chuck 36 of the power tool 35, and the rotation transmission mechanism 20 is connected to a hexagonal hole-shaped connector 37 that passes through the external input shaft 23. It has a tool connection part 38. As a result, the connector 37 can be detachably attached to the tool connector 38 on the other side of the external input shaft 23, and in addition to being driven by the electric motor 17 and the manual handle 28, the power tool 35 can be selected. In this embodiment, the hexagonal hole-shaped tool connecting portion 38 is formed so as to pass through the external input shaft 23, but the tool connecting portion removably holds the connecting tool on the other side of the external input shaft ( Therefore, instead of a hexagonal hole (through hole), a recessed portion having a hexagonal cross section may be formed on the other side of the external input shaft as a tool connecting portion. In addition, the connector and the tool connector may be of any type as long as they can connect the male mold (convex part) and the female mold (concave part) to each other and transmit rotation, and their shapes and combinations can be selected as appropriate. . For example, the male mold (convex part) and the female mold (concave part) may each be formed into a polygonal shape other than a hexagon, or the connector may be a female mold (recess) and the tool connecting part may be a male mold (concave part). ). As explained above, since the clutch 22 is provided between the motor input shaft 18 and the external input shaft 23, rotation is not normally transmitted between the motor input shaft 18 and the external input shaft 23. Therefore, when the power tool 35 is driven, the rotation of the external input shaft 23 is transmitted to the direct-mount output shaft 19 without transmitting it to the motor input shaft 18 to rotate the operating shaft 11 and open the water gate. Can be opened and closed. Here, the drive unit 13 has a casing 40 in which the rotation transmission mechanism 20 is housed, and a motor cover 41 that is attached to the casing 40 and covers the electric motor 17. The other side of the external input shaft 23 is rotatably held in the casing 40 via a first bearing 42, and one side and the other side of the intermediary rotating shaft 31 have second and third bearings 43 and 44, respectively. One side and the other side of the output shaft 19 for direct attachment are rotatably held by the casing 40 via fourth and fifth bearings 45 and 46, respectively. Bearings are preferably used as the first to fifth bearings 42 to 46.

また、ケーシング４０には、図３に示すように、電動工具３５の使用時に、電動工具３５に取付けられた回り止め具４７（図４参照）を保持する工具固定手段４８が設けられている。従って、電動工具３５による駆動時に、電動工具３５をケーシング４０に固定することができ、外部入力軸２３から受ける回転反力により電動工具３５が逆回転することを防止し、確実かつ効率的に水門の開閉作業を行うことができる。
本実施の形態では、図４に示すように、略円柱状に形成した回り止め具４７を電動工具３５の左側部に取付け、それに対応して、図３に示すように、ケーシング４０（外部入力軸２３の左側）に回り止め具４７が挿通される丸孔状の工具固定手段４８を設けたが、回り止め具の断面形状、大きさ及び配置は、適宜、選択することができ、それに対応して、工具固定手段の形状、大きさ及び配置も、適宜、選択することができる。 Further, as shown in FIG. 3, the casing 40 is provided with a tool fixing means 48 that holds a rotation stopper 47 (see FIG. 4) attached to the power tool 35 when the power tool 35 is used. Therefore, when the power tool 35 is driven, the power tool 35 can be fixed to the casing 40, and the power tool 35 is prevented from rotating in the opposite direction due to the rotational reaction force received from the external input shaft 23. can perform opening and closing operations.
In this embodiment, as shown in FIG. 4, a rotation stopper 47 formed in a substantially cylindrical shape is attached to the left side of the power tool 35, and correspondingly, as shown in FIG. Although a round hole-shaped tool fixing means 48 through which a rotation stopper 47 is inserted is provided on the left side of the shaft 23, the cross-sectional shape, size, and arrangement of the rotation stopper can be selected as appropriate. The shape, size and arrangement of the tool fixing means can also be selected as appropriate.

駆動部１３は、図１、図２に示すように、仲介回転軸３１に取付けられたエンコーダ４９を有しており、このエンコーダ４９で検出した仲介回転軸３１の回転量を制御部１５にフィードバックすることにより、水門の開閉量（昇降量）を正確に制御することができる。
第１のギア２４、仲介ギア機構部２５（第３のギア３２と第４のギア３３）及び第２のギア２６は減速機構として機能し、電動モータ１７又は電動工具３５による駆動時に、外部入力軸２３の回転が直付け用出力軸１９に伝達される間に回転速度を下げ、トルクを増幅することができる。なお、仲介ギア機構部（減速機構）の構成は、これに限定されるものではなく、ギアの数、配置及び減速比等は、適宜、選択することができる。また、仲介ギア機構部を省略し、第１のギアに直接、第２のギアを連結（噛合）させることもできる。 As shown in FIGS. 1 and 2, the drive section 13 has an encoder 49 attached to the intermediate rotation shaft 31, and feeds back the amount of rotation of the intermediate rotation shaft 31 detected by the encoder 49 to the control section 15. By doing so, the amount of opening and closing (the amount of elevation and descent) of the water gate can be accurately controlled.
The first gear 24, the intermediary gear mechanism section 25 (the third gear 32 and the fourth gear 33), and the second gear 26 function as a reduction mechanism, and when driven by the electric motor 17 or the power tool 35, the external input While the rotation of the shaft 23 is transmitted to the output shaft 19 for direct attachment, the rotation speed can be lowered and the torque can be amplified. Note that the configuration of the intermediary gear mechanism (reduction mechanism) is not limited to this, and the number of gears, arrangement, reduction ratio, etc. can be selected as appropriate. Furthermore, the intermediate gear mechanism can be omitted and the second gear can be directly connected (meshed) with the first gear.

電動モータ１７による駆動は、図１に示すように、遠隔コントローラ１４から制御部１５に送信される制御信号に基づいて、制御部１５で駆動部１３（電動モータ１７、クラッチ２２）の動作を制御することにより行われる。クラッチ２２としては電磁クラッチが好適に用いられ、クラッチ２２の動作は電動モータ１７のオンオフと連動（同期）している。従って、先に説明したように、電動モータ１７による駆動を開始する時には、それに連動（同期）して、モータ用入力軸１８の回転が外部入力軸２３に伝達されるようにクラッチ２２が動作し、電動モータ１７による駆動を停止する時には、それに連動（同期）して、モータ用入力軸１８と外部入力軸２３の間で回転が伝達されないようにクラッチ２２が動作（初期状態に復帰）する。遠隔コントローラ１４には、例えば、制御部１５（電動モータ１７）の電源のオンとオフを切替える電源ボタンと、水門の上昇ボタン及び下降ボタンがあり、作業者が遠隔コントローラ１４を操作することにより、電動モータ１７による水門の開閉作業を行うことができる。なお、遠隔コントローラ１４に緊急停止ボタンを設けることにより、緊急時に電動モータ１７を直ちに停止させて、水門の昇降を停止させることができる。 As shown in FIG. 1, the electric motor 17 is driven by controlling the operation of the drive unit 13 (electric motor 17, clutch 22) by the control unit 15 based on a control signal sent from the remote controller 14 to the control unit 15. It is done by doing. An electromagnetic clutch is suitably used as the clutch 22, and the operation of the clutch 22 is interlocked (synchronized) with the on/off of the electric motor 17. Therefore, as explained above, when driving by the electric motor 17 is started, the clutch 22 is operated in conjunction with (synchronization with) the drive so that the rotation of the motor input shaft 18 is transmitted to the external input shaft 23. When the drive by the electric motor 17 is stopped, the clutch 22 operates (returns to the initial state) so that rotation is not transmitted between the motor input shaft 18 and the external input shaft 23 in conjunction with (synchronization with) the drive by the electric motor 17. The remote controller 14 includes, for example, a power button that turns on and off the power of the control unit 15 (electric motor 17), and a rise button and a fall button for the water gate, and when the operator operates the remote controller 14, The electric motor 17 can open and close the water gate. In addition, by providing an emergency stop button on the remote controller 14, the electric motor 17 can be immediately stopped in an emergency, and the raising and lowering of the water gate can be stopped.

制御部１５は、図１に示すように、遠隔コントローラ１４から送信される制御信号を受信アンテナ５０を介して受信する受信手段や、受信手段で受信した制御信号及びエンコーダ４９からフィードバックされる信号（フィードバックパルス）に基いて電動モータ１７やクラッチ２２の動作を指示する指示手段等を備えたメインコントローラ５１の他に、バッテリー５２を内蔵することができる。これにより、停電等で商用電源からの電力供給が停止した時でも、充電されたバッテリー５２から駆動部１３の動作に必要な電力を供給することができる。また、商用電源が利用できない場所に水門が設置されている場合は、バッテリー５２に太陽光パネル５３を接続し、太陽光発電で発電した電力でバッテリー５２を充電することにより、それまで電力が使用できなかった場所でも、水門の開閉作業の電動化を図ることができる。但し、商用電源が利用できる場所であっても、太陽光パネル５３を設置して、商用電源の使用量を削減することが可能である。なお、バッテリー５２の充電はメインコントローラ５１によって制御される。また、制御部１５が電源ランプ５４を備えることにより、駆動部１３（電動モータ１７）が駆動中か否かを確認することができる。図１では、駆動部１３とメインコントローラ５１を接続する信号ケーブル、駆動部１３とバッテリー５２を接続する電源ケーブル、バッテリー５２と太陽光パネル５３を接続する電源ケーブル等を省略した。なお、信号ケーブルと電源ケーブルは独立していてもよいし、可能な範囲で（一部を）複合化してもよい。 As shown in FIG. 1, the control unit 15 includes a receiving means for receiving a control signal transmitted from the remote controller 14 via a receiving antenna 50, a control signal received by the receiving means, and a signal fed back from the encoder 49 ( In addition to the main controller 51, which includes instruction means for instructing the operation of the electric motor 17 and the clutch 22 based on feedback pulses), a battery 52 can be built-in. Thereby, even when the power supply from the commercial power supply is stopped due to a power outage or the like, the charged battery 52 can supply the power necessary for the operation of the drive unit 13. In addition, if the water gate is installed in a place where commercial power is not available, the solar panel 53 can be connected to the battery 52 and the battery 52 can be charged with the electricity generated by solar power, thereby reducing the amount of electricity used until then. Even in places where this is not possible, it is possible to electrify the opening and closing of water gates. However, even in places where commercial power is available, it is possible to install the solar panel 53 to reduce the amount of commercial power used. Note that charging of the battery 52 is controlled by the main controller 51. Furthermore, since the control unit 15 includes the power lamp 54, it is possible to check whether the drive unit 13 (electric motor 17) is being driven. In FIG. 1, a signal cable connecting the drive unit 13 and the main controller 51, a power cable connecting the drive unit 13 and the battery 52, a power cable connecting the battery 52 and the solar panel 53, and the like are omitted. Note that the signal cable and the power cable may be independent, or may be (partially) combined to the extent possible.

以上のように構成された水門開閉器用駆動装置１０によれば、既存の手動式の水門開閉器１２を電動化することができ、必要に応じて、遠隔操作が可能な電動モータ１７による駆動、電動工具３５による駆動及び手動ハンドル２８による駆動を選択する（切替える）ことができ、多様性に優れる。
なお、上記実施の形態では、図１に示したように、駆動部１３の直付け用出力軸１９を水門開閉器１２の操作軸１１に連結する場合について説明したが、必要に応じて、図６に示す変形例の駆動部５５のように、回転伝達機構２０が収容されるケーシング４０の下方に脚部５６を連結し、嵩上げを行うことができる。 According to the water gate switch drive device 10 configured as described above, the existing manual water gate switch 12 can be electrified, and if necessary, the drive by the electric motor 17 that can be remotely controlled, It is possible to select (switch) between driving by the electric tool 35 and driving by the manual handle 28, providing excellent versatility.
In the above embodiment, as shown in FIG. 1, a case has been described in which the direct-mounting output shaft 19 of the drive unit 13 is connected to the operation shaft 11 of the water gate switch 12. Like the drive part 55 of the modification shown in 6, the leg part 56 can be connected to the lower part of the casing 40 in which the rotation transmission mechanism 20 is accommodated, and it can raise the height.

駆動部５５は、直付け用出力軸１９に取付けられた第１のスプロケット５８と、脚部５６の高さ方向の途中に回転可能に保持され直付け用出力軸１９の代わりに一側が操作軸１１に連結される嵩上げ用出力軸５９と、嵩上げ用出力軸５９に取付けられた第２のスプロケット６０を有している。そして、第１のスプロケット５８と第２のスプロケット６０に、直付け用出力軸１９の回転を嵩上げ用出力軸５９に伝達するチェーン６１が巻回されている。これにより、直付け用出力軸１９及び外部入力軸２３の位置（高さ）を嵩上げすることができ、手動ハンドル２８による駆動及び電動工具３５による駆動を楽な姿勢で行うことができる。駆動部５５は、前述の遠隔コントローラ１４及び制御部１５と共に使用することにより、水門開閉器用駆動装置１０と同様の作用、効果を得ることができる。 The drive part 55 is rotatably held midway in the height direction of the leg part 56 with a first sprocket 58 attached to the output shaft 19 for direct mounting, and one side is an operating shaft instead of the output shaft 19 for direct mounting. 11, and a second sprocket 60 attached to the raising output shaft 59. A chain 61 is wound around the first sprocket 58 and the second sprocket 60 for transmitting the rotation of the output shaft 19 for direct attachment to the output shaft 59 for raising. Thereby, the position (height) of the direct-mount output shaft 19 and the external input shaft 23 can be raised, and driving by the manual handle 28 and the electric tool 35 can be performed in a comfortable posture. By using the drive unit 55 together with the above-mentioned remote controller 14 and control unit 15, it is possible to obtain the same functions and effects as those of the water gate switch drive device 10.

ここで、脚部５６は筒型（中空状）に形成され、嵩上げ用出力軸５９、第２のスプロケット６０及びチェーン６１を収容するハウジングを兼ねており、嵩上げ用出力軸５９の両端を回転可能に保持する軸受６２、６３を備えている。
なお、駆動部１３では、直付け用出力軸１９に第１のスプロケットは取付けられていないが、脚部５６による嵩上げの要否に関わらず、直付け用出力軸１９に第１のスプロケットを取付けておけば、ケーシング４０内の回転伝達機構の構造を共通化することができる。 Here, the leg portion 56 is formed in a cylindrical shape (hollow shape), and serves as a housing for accommodating the output shaft 59 for raising the height, the second sprocket 60, and the chain 61, and can rotate both ends of the output shaft 59 for raising the height. It is equipped with bearings 62 and 63 that hold it in place.
Note that in the drive unit 13, the first sprocket is not attached to the output shaft 19 for direct attachment, but the first sprocket can be attached to the output shaft 19 for direct attachment regardless of whether or not raising the height by the legs 56 is necessary. By doing so, the structure of the rotation transmission mechanism within the casing 40 can be made common.

例えば、上記実施の形態において、嵩上げ用出力軸の他側に手動ハンドルが取付け可能な構成とすることもできる。
また、上記実施の形態では、直付け用出力軸の一側を操作軸に連結し、直付け用出力軸の他側に手動ハンドルが取付け可能なハンドル取付け部を設けたが、直付け用出力軸の他側を操作軸に連結し、直付け用出力軸の一側に手動ハンドルが取付け可能なハンドル取付け部を設けることもできる。なお、ハンドル取付け部に取付ける手動ハンドルは、既存の水門開閉器で使用されていた手動ハンドルをそのまま使用してもよいし、別の手動ハンドルを使用してもよい。
電動工具としては、主に電動ドライバー又は電動ドリルが用いられるが、その他の手持ち式の電動工具を適宜、用いることができる。なお、電動工具は、電池又は充電式のバッテリーで駆動できるものが好ましいが、制御部のバッテリーで駆動できるようにしてもよい。
また、遠隔コントローラには、ＩＤ及び／又はパスワードによる認証機能を搭載し、誤操作や悪戯を防止することができる。
エンコーダとしてはロータリエンコーダが好適に用いられるが、最終的に制御部で水門の開閉量（昇降量）を把握することができればよく、仲介回転軸の回転量を検出する代わりに、モータ用入力軸又は直付け用出力軸の回転量を検出してもよい。 Although the embodiments of the present invention have been described above, the present invention is not limited to the configurations described in the embodiments described above, and can be considered within the scope of the matters described in the claims.

It is also possible to connect the other side of the shaft to the operating shaft, and provide a handle attachment portion to which a manual handle can be attached to one side of the output shaft for direct attachment. As the manual handle attached to the handle attachment part, the manual handle used in the existing water gate opener may be used as is, or a different manual handle may be used.

Moreover, the remote controller is equipped with an authentication function using an ID and/or password, so that erroneous operations and mischief can be prevented.
