Description

  The present invention relates to an opening degree measuring instrument for measuring the opening degree of an opening / closing member of a running water control device, for example, the opening degree of a sluice door or a valve body of a water channel.

  Conventionally, a water flow control device for adjusting the amount of water is installed in a river sluice or channel for water intake or drainage. As this running water control device, a spindle type gate, a rack type gate, a slide gate valve and the like are generally known.

  The spindle type gate and the rack type gate are used when opening and closing the sluice gate, and are connected to the door for opening and closing the sluice gate (hereinafter referred to as an opening and closing member), and are used as a driving force for the opening and closing operation. An operation shaft for transmitting and a handle for raising and lowering the operation shaft are provided. The slide gate valve is used when opening and closing a water channel. A valve body that opens and closes the water channel (hereinafter referred to as an opening / closing member), an operation shaft connected to the valve body, and the operation shaft. And a handle for raising and lowering.

  In any of the above-described flowing water adjusting devices, the opening / closing member is moved up and down via the operation shaft so as to obtain an appropriate amount of flowing water, and the opening degree of the opening / closing member is adjusted. Therefore, the opening / closing operation of the opening / closing member may require accuracy, and it is also necessary for an administrator to visually confirm the opening degree of the opening / closing member.

  From the above, various opening degree measuring instruments for measuring the opening degree of the opening and closing member have been devised. For example, a tape-shaped display member that is color-divided into an upper and lower divided area, that is, an open area and a closed area of the opening / closing member, and winding and feeding can be performed so that both ends of the display member can be moved in the vertical direction. In order to be able to see the rate at which the two color-coded regions change according to the amount of elevation of the operating shaft, the longitudinal direction can be seen. The thing provided with the ruler member made from transparent resin to which the scale was attached | subjected along is known (patent document 1).

  In the two color-coded areas of the display member, the area indicating the closed state is disposed above the display member, the area indicating the open state is disposed below the display member, and each area is colored. It is divided and displayed by. That is, the amount of movement of the open / close member from the fully closed state to the fully open state and the state thereof are displayed by the length and color of each region.

  And the ratio of the opening degree of an opening-and-closing member can be confirmed now by visually observing the scale of a ruler member and the position of the area | region of the display member which can be seen through from a ruler member.

Japanese Patent Laid-Open No. 11-22855

  However, in the case of the conventional opening degree measuring instrument, the operation shaft and the display member are connected and displayed so that the color-coded region of the display member is interlocked with the up-and-down movement of the operation shaft of the opening and closing member. Since it is necessary to read the area | region of a display member with the scale of a ruler member, there exists a problem that it is difficult to attach to the various existing flowing water control apparatuses mentioned above.

  Moreover, since the opening degree of the opening / closing member is determined by the displayed ratio of the color-coded area, the opening degree of the opening / closing member cannot be measured accurately, that is, in a state close to the actual measurement value. In other words, there is a problem that the running water adjusting device cannot be adjusted accurately.

  The present invention has been made in view of such circumstances, and can be easily installed in various existing water flow control devices, and accurately measures the opening degree of an opening / closing member that opens and closes a sluice and a water channel so that the water flow control device can be accurately An object of the present invention is to provide an opening degree measuring instrument for a running water control device that can be adjusted to a constant level.

  An opening degree measuring instrument for a running water control apparatus according to the present invention includes an opening / closing member that opens and closes a sluice and a water channel, and operation shafts 4, 12, and 22 that are connected to the opening / closing member and are displaced together with the opening / closing member by an opening / closing operation. In the opening degree measuring instrument of the running water control device, the length information is provided with an index F indicating the reference position and the displacement position of the operation shafts 4, 12, and 22 and first intervals H1 to H10 along the longitudinal direction.

A ruler member T, T1, T2 on which a second scale X, which is attached in a displaced manner and is provided with the same identification information with respect to the same displacement amount from the first scale Y, is provided; In the first scale Y and the second scale X of the ruler members T, T1, T2 Based on the position of the target F, characterized in that it is configured to measure an opening degree of the opening and closing member.

  In this case, before the opening / closing operation is performed, the starting point where the index F is located is confirmed on the first scale Y and the second scale X of the ruler members T, T1, T2, and then the index F displaced from the starting point by the opening / closing operation. Are confirmed on the first scale Y and the second scale X of the ruler members T, T1, T2. That is, based on the position of the index F at the displacement point, the longitudinal displacement from the starting point to the displacement point is measured by the length information of the first scale Y, and the identification information of the second scale X is used. Then, a displacement amount that is displaced stepwise from the first scale Y is measured. By doing so, the opening degree of the opening / closing member can be accurately measured. That is, it is possible to accurately adjust the opening ratio of the opening and closing member with respect to the sluice and water channel, and it is possible to accurately adjust the amount of flowing water (a small flow rate such as a maintenance flow rate and irrigation water) in the flow rate adjusting device.

  In addition, according to the present invention, it is possible to adopt a configuration in which the length information and the identification information are any number, color, character, symbol, barcode, slit, or a combination thereof.

  In this case, the length information and the identification information can be configured by numbers, colors, characters, symbols, barcodes, slits, or a combination thereof. However, in order to measure the opening degree, it is necessary to replace it with a length (number) when it is constituted by information other than numbers, that is, information on colors, characters, symbols, barcodes, and slits 30.

  Further, according to the present invention, it is possible to adopt a configuration in which the ruler members T, T1, and T2 are any one of a cylindrical shape, a concave shape, and a flat plate.

  In this case, ruler members T, T1, and T2 corresponding to the shapes of the operation shafts 4, 12, and 22 of the existing running water control device can be used. That is, it becomes easy to cope with the existing running water control device.

  Moreover, according to this invention, the structure which makes the said ruler members T, T1, T2 transparent or semi-transparent is also employable.

  In this case, transparent or semi-transparent ruler members T, T1, T2 can be arranged in front of the operation shafts 4, 12, 22, and the first scale Y and the second scale X of the ruler members T, T1, T2 The index F can be positioned directly behind, making it easier to see.

  In addition, according to the present invention, a configuration in which a detachable magnet M, double-sided tape, and adhesive are used as a fixing member for fixing the ruler members T, T1, T2 to a reference horizontal plane is adopted. You can also.

  According to the present invention, the axial and circumferential displacements of the operating shaft connected to the opening / closing member of the running water control device are represented by the index indicating the reference position and displacement position of the operating shaft and the ruler attached along the longitudinal direction. Since the measurement is performed using the first scale of the member and the second scale that is attached stepwise in a direction orthogonal to the longitudinal direction, the opening degree of the opening / closing member is accurately measured. In addition, the running water control device can be adjusted accurately.

  Further, the above-described index indicates the reference position and displacement position of the operation shaft, and the ruler member measures the opening based on the reference position and displacement position of the index, and there is no complicated mechanism. It can be easily provided in an existing running water control device.
