PROBLEM TO BE SOLVED: To provide a method and a device for opening/closing a valve.SOLUTION: A method for opening/closing a valve includes the steps of: holding an electric power tool in a person's arm; rotating an input part 3 by rotating an output part 2 of the electric power tool; transmitting a rotational force of the input part 3 to a reduction gear 4; rotating a drive part 6 by rotation of the reduction gear 4; and opening/closing the valve by rotating a part-to-be-operated 5 of the valve by rotation of the drive part 6.

Description

本発明は、水門のようなバルブの開閉方法および装置に関する。 The present invention relates to a method and an apparatus for opening and closing a valve such as a sluice.

例えば、農業用の用水路のゲート（バルブ）には手動式と電動式とがある。近年、度々生じるゲリラ豪雨時等には、必要に応じて前記ゲートを開閉する必要がある。 For example, there are two types of gates (valves) for agricultural irrigation channels: manual and electric. In recent years, it is necessary to open and close the gate as necessary in the event of heavy guerrilla rain.

手動式のゲートの場合、オペレータの高齢化に伴いゲートを開閉する作業に時間を要し、緊急時の対応に遅れが生じ易い。 In the case of a manual gate, it takes time to open and close the gate with the aging of the operator, and a response to an emergency is likely to be delayed.

一方、電動式のゲートの場合、屋外に設置された制御盤内の電気系統が損傷していることが少なからずあり、そのため、ゲートの開閉自体ができないことがある。 On the other hand, in the case of an electric gate, the electrical system in the control panel installed outdoors is often damaged, and therefore the gate itself cannot be opened and closed.

かかる実情に鑑み、本出願人は車載バッテリーを利用したバルブの開閉装置を提案しており、出願している。 In view of this situation, the present applicant has proposed and applied for a valve opening / closing device using an in-vehicle battery.

登録実用新案公報第３１７５５１１号（要約）Registered Utility Model Publication No. 3175511 (Summary)

しかし、かかるバッテリーを利用したものでは、車両がゲートの近くまで侵入したり、車両をゲートの極く近い位置に駐車する必要がある。 However, in the case of using such a battery, it is necessary for the vehicle to enter the vicinity of the gate or to park the vehicle very close to the gate.

また、バッテリーの電力で電動モータを駆動するための電気回路等に市販品を使うことができず、コストアップの要因となる。 In addition, a commercially available product cannot be used for an electric circuit or the like for driving an electric motor with battery power, which causes an increase in cost.

かかる問題は農業用水だけでなく、上下水道などの水路においても同様に生じる。 Such a problem occurs not only in agricultural water but also in waterways such as water and sewage systems.

本発明の目的は、前述の課題を解決し得るバルブの開閉方法および装置を提供することである。 An object of the present invention is to provide a valve opening / closing method and apparatus capable of solving the above-described problems.

本バルブの開閉装置は、電動工具の出力部に係合し前記出力部の回転で回転する入力部と、
前記入力部の回転数を減少させる減速機と、
前記減速機の回転で回転し、バルブの被操作部を回転駆動させる駆動部と、
構造物に固定され前記減速機のケースを支持するベースとを備える。 The valve opening and closing device includes an input unit that engages with an output unit of an electric tool and rotates by rotation of the output unit
A speed reducer that reduces the rotational speed of the input unit;
A drive unit that rotates by the rotation of the speed reducer and drives the operated portion of the valve to rotate;
A base that is fixed to the structure and supports the case of the speed reducer.

かかる装置を用いた本バルブの開閉方法は、電動工具を腕に抱える工程と、
前記電動工具の出力部をバルブ開閉装置の入力部に係合させる工程と、
前記電動工具の出力部を回転させて前記入力部を回転させる工程と、
前記入力部の回転力を前記装置の減速機に伝達する工程と、
前記減速機の回転で前記装置の駆動部を回転させる工程と、
前記駆動部の回転でバルブの被操作部を回転させて、バルブを開閉させる工程とを備える。 The valve opening and closing method using such a device includes a step of holding an electric tool on an arm,
Engaging the output part of the electric tool with the input part of the valve opening and closing device;
Rotating the output part of the power tool to rotate the input part;
Transmitting the rotational force of the input unit to the speed reducer of the device;
Rotating the drive unit of the device by rotation of the speed reducer;
A step of rotating the operated portion of the valve by the rotation of the driving unit to open and close the valve.

本発明によれば、電動工具を用いてバルブを開閉するので、緊急時の対応に遅れが生じにくい。
また、電動式のバルブと異なり、電気系統が損傷しているおそれもない。
更に、車両をゲートの極く近い位置に駐車する必要もない。
また、減速機やヒンジなどの主たる部品は一般に市販品を採用することができ、コストダウンを図り得る。 According to the present invention, since the valve is opened and closed using the electric tool, it is difficult to cause a delay in the emergency response.
Further, unlike an electric valve, there is no possibility that the electric system is damaged.
Furthermore, it is not necessary to park the vehicle at a position very close to the gate.
In addition, as a main part such as a speed reducer and a hinge, a commercially available product can be generally used, and the cost can be reduced.

本発明の開閉装置の一実施例を示す正面図である。It is a front view which shows one Example of the opening / closing apparatus of this invention. 同側面図である。It is the same side view.

好ましくは、前記減速機と前記ベースとの間には、
前記減速機及び駆動部の姿勢を変更可能に支持するヒンジと、
前記ヒンジにより前記減速機及び駆動部が支持された状態において前記減速機及び駆動部の姿勢を変更するための調節具とが介挿されている。 Preferably, between the speed reducer and the base,
A hinge for supporting a change in posture of the speed reducer and the drive unit;
An adjuster for changing the posture of the speed reducer and the drive unit in a state where the speed reducer and the drive unit are supported by the hinge is interposed.

この場合、調節具を操作することにより、駆動部の姿勢を変更でき、したがって、バルブのハンドルに駆動部が適正な接触圧で接触する。 In this case, the attitude of the drive unit can be changed by operating the adjuster, and therefore the drive unit contacts the handle of the valve with an appropriate contact pressure.

図１に示すように、本バルブ開閉装置１は、電動工具の出力部２の回転で回転する入力部３と、前記入力部の回転数を減少させる減速機４と、前記減速機４の回転で回転し、バルブ（図示せず）の被操作部５（ハンドル）を回転駆動させる駆動部６（ウレタン製のローラ）と、構造物７（バルブフレーム）に固定され前記減速機４のケース４０を支持するベース８とを備える。 As shown in FIG. 1, the valve opening / closing device 1 includes an input unit 3 that rotates by rotation of an output unit 2 of an electric tool, a speed reducer 4 that reduces the rotational speed of the input unit, and rotation of the speed reducer 4. And a drive unit 6 (urethane roller) for rotating the operated portion 5 (handle) of a valve (not shown) and a case 40 of the speed reducer 4 fixed to the structure 7 (valve frame). And a base 8 for supporting

なお、電動工具として充電式のドライバ（コードレスインパクトドライバ）を用いることができる。
前記減速機４と前記ベース８との間には、前記減速機４及び駆動部６の姿勢を変更可能に支持するヒンジ９と、前記ヒンジ９により前記減速機４および駆動部６が支持された状態において前記減速機４および駆動部６の姿勢を変更するための調節具１０とが介挿されている。 A rechargeable driver (cordless impact driver) can be used as the electric tool.
Between the speed reducer 4 and the base 8, a hinge 9 that supports the posture of the speed reducer 4 and the drive unit 6 in a changeable manner, and the speed reducer 4 and the drive unit 6 are supported by the hinge 9. In the state, the speed reducer 4 and an adjustment tool 10 for changing the posture of the drive unit 6 are inserted.

なお、出力部２および入力部３の形状は六角孔や六角柱に限定されない。また、バルブの被操作部５はハンドルではなく角錐形などであってもよい。 In addition, the shape of the output part 2 and the input part 3 is not limited to a hexagonal hole or a hexagonal column. Further, the operated portion 5 of the valve may be a pyramid shape instead of a handle.

本実施例の場合、前記減速機４のケース４０および駆動部６はヒンジ９の中心Ｏの周りに回転可能に前記ベース８を介して構造物７に固定されている。前記調節具１０はアイボルト１１の周囲にコイルスプリング１２が外嵌され、ナット１３をアイボルト１１に螺合させて減速機４のケース４０の姿勢を変えることができる。これにより、駆動部６が被操作部５に接触する接触圧が調整される。 In the case of the present embodiment, the case 40 and the drive unit 6 of the speed reducer 4 are fixed to the structure 7 via the base 8 so as to be rotatable around the center O of the hinge 9. The adjuster 10 has a coil spring 12 fitted around the eyebolt 11, and a nut 13 can be screwed onto the eyebolt 11 to change the posture of the case 40 of the speed reducer 4. Thereby, the contact pressure at which the drive unit 6 contacts the operated unit 5 is adjusted.

なお、図２に示すように、前記駆動部６には円周状の溝が設けられていてもよい。この場合、当該溝に断面円形のバルブの被操作部５が嵌まるため両者が滑りにくくなる。 In addition, as shown in FIG. 2, the said drive part 6 may be provided with the circumferential groove | channel. In this case, since the operated portion 5 of the valve having a circular cross section is fitted into the groove, the both are difficult to slip.

つぎに、バルブの開閉方法について説明する。
オペレータは電動工具を腕に抱え、前記電動工具の出力部２をバルブ開閉装置の入力部３に係合させる。ついで、オペレータが前記電動工具の出力部２を回転させて前記入力部３を回転させると、前記入力部３の回転力が前記装置の減速機４に伝達され、前記減速機４の回転で前記装置の駆動部６が回転する。前記駆動部６の回転でバルブの被操作部５が回転され、前記バルブが開閉される。 Next, a method for opening and closing the valve will be described.
The operator holds the electric tool on his / her arm and engages the output part 2 of the electric tool with the input part 3 of the valve opening / closing device. Next, when the operator rotates the output unit 2 of the electric tool to rotate the input unit 3, the rotational force of the input unit 3 is transmitted to the speed reducer 4 of the device, and the rotation of the speed reducer 4 causes the The drive unit 6 of the device rotates. The operated part 5 of the valve is rotated by the rotation of the driving unit 6 and the valve is opened and closed.

本発明は農水や上下水道用のバルブの開閉に利用することができる。 The present invention can be used for opening and closing valves for agricultural water and water and sewage.
