JPS5910609Y2 - Immersion type water quality meter with float - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to an immersion type water quality meter with a float.

As a conventional product of this kind, for example, as shown in Japanese Utility Model Application Publication No. 49-100591, there is one in which a large number of measurement electrodes are integrally attached to the periphery of the float. Therefore, it takes great care and effort to balance the float, and especially when measuring water quality deep below the water surface, long and heavy measuring electrodes must be attached, making it even more difficult to balance the float. It is difficult to remove.

In addition, in this conventional product, the measuring electrodes are integrated into the float along with the cleaning device, and when inspecting the measuring electrodes, replacing the internal liquid, repairing malfunctioning parts, etc., the float must be pulled out of the tank. It was difficult to operate.

The purpose of the present invention is to eliminate the above-mentioned conventional drawbacks and to provide a float-type immersion type water quality meter in which a handle provided for ease of operation also serves as a protection member for important parts of the water quality meter. .

An embodiment of the present invention will be described based on the drawings. As shown in Fig. 1, the sensor holder is made of plastic or metal material such as duralumin and has a hollow shape, and penetrates vertically through the center and the periphery thereof. (Described later) A float A having a hole a for insertion and a bolt hole is made, a water quality measuring sensor 1 for measuring pH etc. is held in the lower part, and a measurement signal of the sensor 1 is transmitted to the upper part for measuring pH' etc. A sensor holder 2 connected with a converter 3 for converting into an instruction signal (made of a highly corrosion-resistant material such as polypropylene, vinyl chloride, stainless steel, etc.).

) and is detachably attached to the float A with a structure as described below.

4 is a jet cleaning type cleaning device also mounted on the float A.

5 and 6 are plates made of metal such as stainless steel, which are arranged on the upper and lower surfaces of the float A and are fastened by bolts 7 inserted into the bolt holes, and are bolted to the upper plate 5. metal fittings 13 and bolts 14 (this 13.1
4 constitutes a fixing fitting.

), the sensor holder 2 is detachably attached to the float A.

7' is a nut, 8 is an indicator, and 9 is a test liquid.

10... is the converter 3 on the upper surface of the upper plate body 5.
A pair of metal handles 10 are fixed by means such as welding so as to be located on both sides of the metal handle 10. As shown in FIG. It is also used as a protector to prevent damage to the converter 3 due to contact with the converter 3.

In the figure, reference numeral 11 indicates a screw hole for bolting the metal fitting 13, and reference numeral 12 indicates a pipe insertion hole for pressure feeding the cleaning medium to the cleaning device 4.

Incidentally, as the cleaning medium in the jet cleaning type cleaning device 4, it is of course possible to use an appropriate medium such as water, chemical solution, air, or a mixture thereof.

Further, as the cleaning device 4, it is possible to employ an appropriate method such as an ultrasonic method, a brush cleaning method, a combination thereof, or a combination of one or two of these methods with a jet cleaning method.

In addition, as sensor 1, in addition to the sensor for pH measurement,
A single measurement sensor such as ORP, DO, etc., or
A plurality of them may be combined and mounted on the float A so that these various measurements can be carried out.

As mentioned above, the present invention has a hole penetrating vertically in the center of the float, a sensor for water quality measurement is held in the lower part of the hole, and a converter in the upper part that converts the measurement signal into an instruction signal. The sensor holder is inserted in a row, and the sensor holder is removably attached to the float using fixing metal fittings, and a pair of handles in the shape of approximately taps are placed on both sides of the transducer. Since the float-equipped immersion type water quality measuring device is constructed by being installed on the float, the following effects can be obtained.

■ When inspecting the water quality measurement sensor, replacing the internal liquid, or repairing a malfunctioning part, all you need to do is remove the sensor holder from the float while the float is immersed, making inspections extremely easy. and can be done in a short time.

■ Since the weight of the water quality measurement sensor, sensor holder, and converter is placed on the center of the float, there is no risk of the balance being lost compared to the case where the sensors are attached to the periphery of the float. Even if a long and heavy sensor holder is used to measure water quality at a certain location, the balance of the float will not be lost, and stable water quality measurement at a desired location is possible.

■ Since a pair of handles are provided, it is not only convenient for transporting the float, but also can be used as a protection member for the converter, without the need for a separate protection member. Damage caused by collision with other objects can be prevented.
