Description

【考案の詳細な説明】〔産業上の利用分野〕本考案は、下水処理場のエアレーシヨンタンク
に設けられた可動堰等の越流深さを測定するため
の測定器に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a measuring device for measuring the overflow depth of a movable weir or the like provided in an aeration tank of a sewage treatment plant.

[Conventional technology]

従来のこの種の越流深さ測定器は、可動堰にそ
の一部として組込まれたものであつた（例えば実
開昭61−71617号公報）。 Conventional overflow depth measuring instruments of this type have been incorporated into movable weirs as part of them (for example, Japanese Utility Model Application Publication No. 71617/1983).

[Problem that the invention attempts to solve]

従つて、従来によるときは、測定器を備えない
可動堰の場合、測定者が目視することにより、堰
板に目盛が付されているときはその目盛を利用し
て、目盛がない場合は専ら測定者の勘に頼つて、
越流深さを知らなければならない。しかし、目視
角度によつて越流や目盛の見え方にバラツキが生
じるため、目盛を利用する場合であつても正確性
に欠き、特に下水処理場のエアレーシヨンタンク
用に可動堰の場合、暗いため、越流深さを目視で
知ることは非常に困難である。 Therefore, in the case of a movable weir without a measuring device, in the case of a movable weir without a measuring device, the measurer can visually check the weir plate, use the scale if the weir plate has a scale, or use the scale if there is no scale. Relying on the intuition of the measurer,
The overflow depth must be known. However, because there are variations in overflow and the appearance of the scale depending on the viewing angle, accuracy is lacking even when using a scale, especially in the case of movable weirs for aeration tanks in sewage treatment plants. Due to the darkness, it is very difficult to visually determine the overflow depth.

また、前述した下水処理場のエアレーシヨンタ
ンク用の可動堰の場合、処理通路の通水初期に越
流深さを調整し、その後は、処理通路の数が増え
るとかしない限りほとんど調整しないのが普通
で、越流深さの測定頻度は極めて小さい。 In addition, in the case of the movable weir for the aeration tank of the sewage treatment plant mentioned above, the overflow depth is adjusted at the beginning of water flowing through the treatment passage, and thereafter it is rarely adjusted unless the number of treatment passages increases. is common, and the frequency of measuring overflow depth is extremely low.

そのため、そのような可動堰に測定器が常設さ

る。 Therefore, if a measuring device is permanently installed on such a movable weir, the measuring device may become clogged with debris, or
Inconveniences such as the overflow flow being obstructed by the measuring device or the odor leaking to the outside from the flow passing through the measuring device occur not only during measurement but also during normal use.

本考案の目的は、平生における前述の不都合の

きる測定器を提供する点にある。 The purpose of the present invention is to provide a measuring device that can easily, quickly, and accurately measure the overflow depth even in the dark while avoiding the above-mentioned inconveniences that occur during normal life. be.

て、それによる作用・効果は次の通りである。 The overflow depth measuring instrument for a movable weir according to the present invention is a portable type that can be attached to and detached from the movable weir. is provided at the lower end of a freely portable measuring rod, the measuring rod holds a float slidably in the rod's longitudinal direction, and the depth of overflow relative to the weir plate is displayed using the float as a guide. A string is connected to the float for suspending and fixing the float to the measuring rod. The effects and effects thereof are as follows.

[Effect]

できる。 By fitting the fitting part at the lower end of the measuring rod to the upper end of the weir plate, the float slides relative to the measuring rod so as to be positioned at a position corresponding to the upper surface of the overflow due to the buoyant force received from the overflow. Then, by suspending and fixing the float with a string to prevent the float from sliding downward due to its own weight relative to the measuring rod, the measuring rod is pulled up, and the value on the scale indicated by the float is read. You can know the depth.

[Effect of idea]

うになつた。 As a result, since it is portable and can be removed from the movable weir, the above-mentioned inconveniences do not arise in the case, and moreover, the fitting part at the lower end of the measuring rod can be used for measurement operations. It only requires three operations: fitting the float to the upper end of the weir plate, pulling up the measuring rod with the float suspended and fixed with a string, and reading the scale. , and can be easily and accurately carried out in a well-lit environment, making it possible to easily, quickly, and accurately determine the overflow depth.

連結して設けたものである。 The portable overflow depth measuring device for movable weirs has a U-shaped fitting part 2 integrated into the lower end of a portable measuring rod 1 for fitting and mounting on the upper end of the weir plate A. A ring-shaped float 3 is provided on the measuring rod 1.
is fitted and held on the outside of the rod so as to be slidable in the longitudinal direction, and the weir plate A is held with the float 3 as a guide.
A string 5 is connected to the float 3 at one end for suspending and fixing the float 3 to the measuring rod 1. .

を示すように形成されている。 Further, the float 3 is prevented from falling off from the lower end of the measuring rod 1 by engagement with the fitting part 2, and in the scale 4, overflow water of the float 3 is removed from the mounting surface 2a of the fitting part 2. The distance L ₁ to the surface equivalent position,
The zero point position is determined so that the distance L ₂ from the zero point to the top surface of the float 3 is equal.
In other words, it is formed to indicate the overflow depth using the upper surface of the float 3 as a guide.

上面が指し示す目盛４の値を読取る。 To explain the measurement procedure using the measuring instrument configured as above, first, as shown in Fig. 2,
With the string 5 loosened, the string 5 is attached to the holder 6 so that the float 3 is located at the bottom where it engages with the fitting part 2.
In this state, the fitting part 2 is fitted to the upper end of the weir plate A, and the string 5 is loosened as the float 3 rises due to the buoyant force from the overflow. 1. Operate the string 5 so that it is suspended and fixed in the raised position relative to the measuring rod 1, and then re-grip the string 5 to the holder 6, or measure the string 5 as shown in FIG. While holding the measuring rod 1 together with the fingers and maintaining its operating state, the measuring rod 1 is pulled up and the value on the scale 4 indicated by the upper surface of the float 3 is read.
