Description

  The present invention relates to a sensor body insertion / extraction device that uses, for example, soil contaminated with petroleum or the like in a purification device by bioremediation using aerobic microorganisms.

  Examples of methods for purifying oil-contaminated soil include solvent extraction and thermal desorption methods that separate contaminated oil, and incineration methods that decompose contaminated oil. The treatment process is necessary, and the incineration method and the thermal desorption method have a problem that the treatment cost becomes high due to the necessity of auxiliary fuel, and the incineration method has a problem that nitrogen oxides are generated by combustion.

  In contrast to these methods, bioremediation, which is a biological treatment method using microorganisms in the soil, has been recognized as a purification method with a low environmental impact in the purification of petroleum-contaminated soil, and many proposals have been made (specially JP 2001-212552, JP 2003-10834).

  Since this bioremediation is a biological treatment method using aerobic soil microorganisms in the soil, it is necessary to supply oxygen and moisture in addition to supplying nutrients to the contaminated soil.

For this reason, in the conventional method, the contaminated soil is turned back by a construction machine, or oxygen is replenished by agitation work using a stirrer, and water is replenished by watering or the like.
JP2001-212552, JP2003-10834

  However, since soil remediation by bioremediation is a biological treatment method using aerobic soil microorganisms in the soil, it is necessary to appropriately maintain and manage the soil environment. It is necessary to monitor the oxygen concentration and water content.

  In conventional bioremediation, monitoring of necessary conditions such as oxygen concentration and water content in soil is performed by a person using a measuring instrument or installing a measurement sensor on any part of the soil as necessary. It was.

  However, for oxygen supplementation, when using a construction machine or stirring work using a contaminated soil purification device, the measurement sensor is removed in advance, or it is re-introduced into the soil after the stirring work is completed. It is necessary to perform the work which takes.

  On the other hand, the sensor body 15 used for measuring the moisture content in the soil is greatly affected by the density of the soil, and in order to perform an accurate measurement, the sensor is kept in a state where the density is kept uniform as shown in FIG. It is necessary to introduce the body 15.

  However, when the sensor inlet 15 is provided in the side part 4 of the soil purification treatment tank by bioremediation as shown in FIG. 8, when the sensor body 15 is pulled out and the soil is stirred, the soil leaks from the inlet 5, In this state, when the sensor body is introduced so that the entire measurement unit is buried in the soil, the force for solidifying the soil is added and the density is changed, so that accurate measurement cannot be performed.

  In order to prevent this, as shown in FIG. 9, it is necessary to attach the plug body 16 to the sensor introduction port 5 while the sensor body 15 is removed, but this work requires a lot of labor and labor.

  Therefore, the present invention introduces a sensor body when a sensor introduction port is provided at the side of a soil purification treatment tank by bioremediation, extracts the sensor body, and plugs the sensor body while the sensor body is being extracted. The purpose of this is to automate the mounting work and to perform accurate measurement with a small number of hands.

  In view of the above circumstances, the present invention provides one or more sensor inlets at an appropriate depth on the side of the sample deposition tank, and the first side of the sample deposition tank in one direction or in the opposite direction. A slide plate that is moved by the cylinder is provided, and a second cylinder and a third cylinder that slide in the direction of the sensor inlet or in the opposite direction are provided side by side on the mounting plate provided on the slide plate. A sensor body insertion / removal device is proposed in which the sensor body is attached to the second cylinder and the plug of the sensor inlet is attached to the third cylinder.

  In the above configuration, when the sensor body is extracted from the sensor inlet and the plug is attached to the sensor inlet, the sensor is detected by the second cylinder when a predetermined signal is confirmed. It is moved in the opposite direction to the inlet, the sensor is pulled out from the sensor inlet, and then the slide plate is moved in one direction by the first cylinder to the position where the sensor inlet and the plug body face each other, and further by the third cylinder. The plug is moved toward the sensor inlet, and the plug is attached to the sensor inlet.

  On the other hand, the removal of the plug body from the sensor inlet and the operation of inserting the sensor body into the sensor inlet will be described. When a predetermined signal is confirmed, the plug is moved from the sensor inlet to the third cylinder. Is moved in the opposite direction, the plug body is removed from the sensor inlet, and then the slide plate is moved in the opposite direction by the first cylinder to the position where the sensor inlet and sensor body face each other, and the sensor body is further moved by the second cylinder. Is moved toward the sensor inlet, and the sensor body is inserted into the sensor inlet.

  That is, in this invention, the sensor body provided on the side part of the soil purification treatment tank or the like by bioremediation is extracted from the sensor introduction port, the plug body is attached to the sensor introduction port, and conversely, the plug body from the sensor introduction port is removed. Removal and insertion of the sensor body into the sensor inlet can be performed with few human hands.

  Further, in the present invention, since the plug body is attached to the sensor inlet while the sensor body is extracted, the sensor body can perform accurate measurement without being affected by soil density or the like. .

  In the present invention, the sensor body is not limited to the measuring device itself for the measurement sample, but also includes a sampling device for the measurement sample.

  In the present invention, not only a soil remediation treatment tank by bioremediation, but opening a sensor introduction port while the sensor is being extracted may cause a sample measurement to be performed in such a way as to adversely affect the measurement. Can be used for sampling.
