Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a suspended water quality detector such as a PH meter, a dissolved oxygen meter, and an activated sludge concentration meter in tap water, sewage, and factory wastewater. For example, the depth from the water surface to the detector exceeds 3 m. The present invention relates to a water quality detection device that facilitates maintenance work of such a submersion type detector.

[0002]

[Prior art]

 Conventionally, as a water quality detection device, there is a submersion type device in which a detector is fixed to the tip of stainless steel or a plastic pipe up to a depth of about 3 m. If the submersion depth exceeds 3 m (the actual length exceeds 5 m due to the height from the water surface to the tank upper surface, for example), it will be difficult to operate. For example, Fig. 2 shows the main structure. Mono is used.

In FIG. 2, reference numeral 10 is a mounting block, and the detector 2 and the nozzle 3 are fixed to one side of the mounting block 10. On the other side, a sensor cable 5 extended from the detector 2, a cleaning piping hose 12 connected to the fixed end side of the nozzle 3, and a chain 11 supporting these are installed. In the above structure, the electrode 13 of the detector suspended by the chain 11 and submerged in water becomes dirty with the passage of time, but it goes from the cleaning pipe hose 12 to the electrode 13 at an appropriate time interval. The cleaning liquid (or air) is sprayed to prevent the electrodes from becoming dirty.

[0004]

[Problems to be solved by the device]

 In the water quality detection device with the above configuration, the detector is moved up and down when performing maintenance work when calibrating or replacing the sensor, but it is necessary to simultaneously traverse the sensor cable, piping hose, and chain when performing the lifting work. However, it is not workable to traverse three different types, and since these cables and wirings are wet with the liquid to be measured and dirt is attached to them, they scatter and the worker There was a problem of getting dirty.

The present invention has been made to solve the above-mentioned problems, and it is necessary to select a cleaning hose having a sufficient strength for accommodating a sensor cable in a hose for cleaning and suspending the sensor as a hose for piping. It is therefore an object of the present invention to provide a water quality detection device that does not require a hanging chain and is easy to maintain.

[0006]

[Means for Solving the Problems]

 The present invention, which solves the above-mentioned problems, has a detector fixed to a mounting block, a sensor cable extended from the detector, a nozzle fixed to the mounting block, and the above-mentioned sensor cable housed at one end thereof. It consists of a flexible piping hose that is airtightly fixed to a mounting block. A cleaning liquid (or air) is introduced from the other end of the flexible piping hose, and the cleaning liquid (or air) is introduced from the tip of the nozzle to the electrode section of the detector. Alternatively, it is characterized in that it is configured to inject air.

[0007]

[Action]

 In the water quality detection device of the present invention, the piping hose suspends the mounting block (detector) and functions as a passage for the cleaning liquid (or air).

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic view of a main part of an embodiment of the present invention. 1 is a mounting block, 2 is a detector such as a PH meter, a dissolved oxygen meter, an activated sludge concentration meter, and 3 is fixed to the mounting block 1. Is a nozzle whose one end is arranged to face the electrode 13 of the detector 2. 4 is a piping hose in which the sensor cable extended from the detector is stored. The piping hose shall be strong enough to withstand the weight of the detector 2 and the mounting block 1 and flexible with a winding radius of 10 to 50 cm. The inner diameter of the hose and the outer diameter of the sensor cable 5 should be the same as the cleaning liquid. The space is formed to the extent that it can be distributed.

One end of the piping hose 4 is airtightly fixed to the mounting block 1 by a hose clamp 6, and the other end is airtightly fixed to one end of the cheese 7 by a hose clamp 6 ′. The sensor cable 5 is pulled out to the outside through a cheese 7 toward a converter (not shown), and the outer periphery of the sensor cable 5 and the cheese 7 are hermetically fixed by a gasket 8 and a gland 9. Reference numeral 15 is an introduction hose, one end of which is hermetically fixed by a hose clamp 6 ', and the other end of which is connected to a cleaning liquid (or air) supply means (not shown).

In the above configuration, the cleaning liquid (or air) is introduced from the introduction hose 15, passes through the piping hose 4 and the through hole 16 formed in the mounting block 1, and from the tip of the nozzle 3 to the electrode 13 of the detector. Gush toward. According to the above configuration, the sensor cable 5 is housed in the piping hose 4, and the piping hose 4 serves both as the chain 11 and the cleaning piping hose 12 shown in the conventional example. Elevating and lowering the detector 2 during maintenance work can be performed extremely easily.
