Hereinafter, the surface deposit detection apparatus 10 of the present invention will be described in detail with reference to the drawings.
1 includes a probe 20, a position detection unit 25, a circulation channel 30, a liquid suction unit 70, a solid-liquid separation unit 40, a solid sorting and holding unit 50, and an analysis unit. 60, a liquid supply unit 80, a water supply amount detection unit 90, a control device 100, and a result display unit 110.

  The probe 20 is disposed so as to come into contact with the surface of the structure 1 that is a measurement object. A cavity 21, which is a space defined so as to be recessed from the surface, is formed on the surface of the probe 20 that contacts the surface of the structure 1. The cavity 21 of the probe 20 is isolated from the outside of the probe 20 by a partition wall that defines the cavity 21 when the probe 20 is in contact with the surface of the structure 1. Fresh water (liquid) such as distilled water is introduced into the cavity 21 from the outside of the probe 20 through the introduction path 22.

  Further, the liquid introduced into the cavity 21 is led out of the probe 20 through the discharge path 23. The liquid passing through the probe 20 through the introduction path 22 and the discharge path 23 comes into contact with the surface of the structure 1 when present in the cavity 21. Thereby, contaminants (for example, salt and oil) on the surface of the structure 1 are eluted in the liquid, and the liquid becomes a contaminated solution. That is, the probe 20 generates a contaminated solution based on the supplied liquid. In addition, solids, such as deposits on the surface of the structure 1, are mixed into the contaminated solution by being peeled off.

  The position detection unit 25 is a sensor that detects where the probe 20 is located on the surface of the structure 1. In the present embodiment, the surface of the structure 1 is partitioned into a plurality of regions A1, A2, A3, B1, B2, B3, C1, C2, and C3, for example, as shown in FIG. It is detected in which region the probe 20 is located. The position detection unit 25 detects in which region the probe 20 exists, for example, by collating the position of the probe 20 in the XYZ coordinates with the three-dimensional CAD data of the structure 1. The position detector 25 may be configured to detect the shape of the structure 1 to be inspected by detecting the position and angle of the probe 20. In addition, the surface shape of the structure 1 may be either a planar shape or a curved surface shape.

The circulation channel 30 is a channel for circulating a liquid (including a contaminated solution) between the probe 20 and the analysis unit 60, and includes a first channel 31 and a second channel 32.
One end of the first flow path 31 is connected to the introduction path 22 of the probe 20, and the other end is connected to the analysis unit 60. One end of the second flow path 32 is connected to the discharge path 23 of the probe 20, and the other end is connected to the analysis unit 60. A liquid circulates between the probe 20 and the analysis unit 60 in the first channel 31 and the second channel 32. More specifically, the liquid flows in the first flow path 31 from the discharge path 23 of the probe 20 toward the analysis unit 60, and the liquid flows in the second flow path 32 from the analysis unit 60 to the introduction path 22 of the probe 20. Circulate towards

  The liquid suction unit 70 has a role of promoting the circulation of the liquid in the circulation channel 30. The liquid suction unit 70 of the present embodiment employs an ejector system including a compressor 71 and an ejector 72. That is, the ejector 72 is installed in the middle of the first flow path 31 in the circulation flow path 30, and by supplying the compressed air sent from the compressor 71 to the first flow path 31, the compressed air is supplied to the compressed air in the first flow path 31. The liquid is attracted to promote the circulation of the liquid. As a result, the liquid is circulated from the probe 20 to the analysis unit 60 in the first flow path 31, in the first flow path 31 from the probe 20 to the analysis unit 60, and further in the second flow path 32. The liquid circulates from the analysis unit 60 toward the probe 20.

The solid-liquid separation unit 40 is provided in the circulation channel 30 and separates a solid component from the contaminated solution flowing through the circulation channel 30. The solid-liquid separation part 40 of the present embodiment is provided between the probe 20 and the liquid suction part 70 in the first flow path 31.
For example, a filter can be employed as the solid-liquid separation unit 40. Since the filter is installed in the flow area of the contaminated solution, solids mixed in the contaminated solution are captured by the filter. The solid thus captured by the filter is introduced into, for example, the solid outlet path 41 branched from the circulation flow path 30 by causing the liquid to flow backward in the circulation flow path 30, for example. In addition, as long as the solid captured by the filter can be introduced into the solid lead-out path 41, other means may be used.

For example, a centrifuge may be used as the solid-liquid separator 40. Thus, the solid separated from the liquid is introduced into the solid outlet path 41.
Furthermore, as the solid-liquid separation unit 40, another known configuration may be adopted. In any configuration, the solid component is introduced from the contaminated solution flowing through the circulation channel 30 into the solid outlet channel 41, and the liquid circulates in the circulation channel 30.

The solid sorting and holding unit 50 has a role of holding the solid separated from the contaminated solution by the solid-liquid separation unit 40 for each region of the structure 1 from which the solid has been peeled off.
As shown in FIG. 3, the solid sorting and holding unit 50 is configured, for example, by connecting a plurality of solid bottles 51 in a straight line. In the present embodiment, the end of the solid lead-out path 41 is open at the top of the solid bottles 51 arranged side by side. Then, these solid bottles 51 are moved in the connecting direction (left-right direction in FIG. 3) by an actuator (not shown) so that the solid falling from the solid lead-out path 41 is accommodated in any one of the solid bottles 51. It has become. That is, when the solid bottle 51 moves, the solid bottle 51 corresponding to the end of the solid lead-out path 41 is changed, and thereby the solid bottle 51 in which the solid falling from the solid lead-out path 41 is accommodated is changed. .

As shown in FIG. 1, the analysis unit 60 includes a liquid sorting and holding unit 61 and a concentration detector 63.
The liquid sorting and holding unit 61 has a role of holding the contaminated solution for each region of the structure 1.
As shown in FIG. 4, the solid sorting and holding unit 50 is configured, for example, by connecting a plurality of liquid bottles 62 in a straight line. In the present embodiment, the end of the first flow path 31 in the circulation flow path 30 is open above the liquid bottles 62 arranged side by side. Then, these liquid bottles 62 are moved in the connecting direction (left-right direction in FIG. 4) by an actuator (not shown) so that the contaminated solution dropped from the first flow path 31 is accommodated in any one of the solid bottles 51. It has become. That is, when the liquid bottle 62 moves, the liquid bottle 62 corresponding to the end of the first flow path 31 is changed, and thereby the liquid bottle 62 in which the contaminated solution dripping from the first flow path 31 is stored is changed. The

  Although not shown, the end of the second flow channel 32 on the analysis unit 60 side is connected to the liquid bottle 62 corresponding to the first flow channel 31, whereby the probe 20 and the first flow channel 31 are connected. The contaminated solution can be circulated sequentially through the liquid bottle 62 and the second flow path 32. When the circulation is stopped, all the contaminated solution is finally stored in the liquid bottle 62 corresponding to the first flow path 31. The circulation can be stopped by operating a valve (not shown), for example.

  The concentration detector 63 is a sensor that detects the concentration of the contaminated solution contained in the liquid bottle 62 of the liquid sorting and holding unit 61. The concentration detector 63 of this embodiment detects the electrical conductivity of the contaminated solution contained in the liquid bottle 62 as the concentration. Based on the concentration and the amount of the contaminated solution, the absolute amount of the contaminant in the contaminated solution can be obtained. The absolute amount of this pollutant indicates the degree of contamination, and the greater the absolute amount of contaminant, the greater the contamination.

The liquid supply unit 80 has a role of supplying fresh water as a liquid to the circulation channel 30. The liquid supply unit 80 includes a fresh water tank 81, a pump 82, and a liquid supply path 83.
The fresh water tank 81 is a tank in which fresh water is stored. One end of the liquid supply path 83 is connected in communication with the inside of the fresh water tank 81, and the other end is connected to the second flow path 32 in the circulation flow path 30. The pump 82 is installed in the middle of the liquid supply path 83 and is driven to supply the fresh water in the fresh water tank 81 to the second flow path 32 via the liquid supply path 83. As a result, fresh water is sequentially supplied to the circulation channel 30, and coupled with the action of the liquid suction unit 70 described above, liquid is supplied between the probe 20 and the analysis unit 60 while fresh water is sequentially supplied to the circulation channel 30. Circulate.

  The water supply amount detection unit 90 detects the water supply amount of the liquid (fresh water) supplied into the circulation channel 30 by the liquid supply unit 80. The liquid supply by the liquid supply unit 80 is performed for each region of the surface of the structure. Therefore, the amount of water detected by the water amount detector 90 is detected for each region.

  Next, the control device 100 will be described. As shown in FIG. 5, the control device 100 includes a position information acquisition unit 101, a water supply amount acquisition unit 102, a concentration acquisition unit 103, a solid information storage unit 104, a solid storage location change unit 105, and a liquid storage. The location change unit 106, the contamination degree calculation unit 107, the liquid information storage unit 108, and the solid information storage unit 104 are included.

The position information acquisition unit 101 receives the position information of the probe 20 from the position detection unit 25. Thereby, it is recognized in which region the probe 20 is located.
The water supply amount detection unit 90 receives water supply amount information from the water supply amount detection unit 90 detected for each region. This water supply amount information is information corresponding to each area.
The density information from the density detection unit is input to the density acquisition unit 103. The density information is also information corresponding to each region.

  The position information of the probe 20 from the position information acquisition unit 101 is input to the solid container changing unit 105. The solid storage location changing unit 105 sends a solid storage location change signal to the solid sorting and holding unit 50 when the region where the probe 20 is located is changed. Accordingly, the solid sorting and holding unit 50 changes the solid bottle 51 in which the solid is accommodated by operating an actuator (not shown).

  The liquid storage location changing unit 106 receives the position information of the probe 20 from the position information acquiring unit 101. The liquid storage location changing unit 106 sends a liquid storage location change signal to the liquid sorting and holding unit 61 when the region where the probe 20 is located is changed. Accordingly, the liquid sorting and holding unit 61 changes the liquid bottle 62 in which the contaminated solution is accommodated by operating an actuator (not shown).

  The contamination degree calculation unit 107 calculates the amount of contaminants in the contaminated solution based on the water supply amount information input from the water supply amount acquisition unit 102 and the concentration information input from the concentration acquisition unit 103. The amount of this contaminant corresponds to the degree of contamination indicating the degree of contamination of each area on the surface of the structure 1.

  The solid information storage unit 104 receives the positional information of the probe 20 from the positional information storage and the solid bottle information from the solid container changing unit 105. Here, the solid bottle information is information indicating which of the solid bottles 51 is currently a solid container. Thereby, the solid information storage unit 104 stores the positional information (region) of the probe 20 and the bottle information (bottle number) for the solid in association with each other.

  The liquid information storage unit 108 receives position information of the probe 20 from the position information storage unit, contamination level information from the contamination level calculation unit 107, and liquid bottle information from the liquid information storage unit 108. Here, the liquid bottle information is information indicating which liquid bottle 62 is currently the target for containing the contaminated solution. Accordingly, the liquid information storage unit 108 stores the positional information (region) of the probe 20, the contamination degree of the contaminated solution (absolute amount of contaminant), and the liquid bottle information (bottle number) in association with each other.

The result display unit 110 displays the information stored in the solid information storage unit 104 and the liquid information storage unit 108 on, for example, a display. More specifically, the correspondence between the position information (region) of the probe 20 stored in the solid information storage unit 104 and the bottle information for the solid, and the positional information of the probe 20 stored in the liquid information storage unit 108 and the contamination solution are stored. The correspondence between the contamination level and the bottle information for liquid is displayed.
If the position detection unit 25 can detect the shape of the structure 1 as described above, the result display unit 110 determines the shape of the structure 1 based on the shape information of the structure 1 from the position detection unit 25. The map may be displayed, and the information stored in each of the solid information storage unit 104 and the liquid information storage unit 108 may be displayed for each area of the map.
In addition, the result display unit 110 may be provided integrally with the control device 100.

Next, the usage method of the surface deposit | attachment detection apparatus 10 of this embodiment is demonstrated.
When the contaminants on the surface of the structure 1 are detected by the surface adhering matter detection device 10, the probe 20 is scanned so that the probe 20 sequentially passes through each region of the surface of the structure 1. The surface of the object 1 is scanned. For example, as shown in FIG. 2, the scanning of the probe 20 sequentially scans each region with A1, B1, C1, C2, B2, A2, A3, B3, and C3. When the probe 20 is positioned in each region, the separated solid in each region is collected and the eluted contaminant is acquired.

Here, the collection of the solid in the region A1 will be described with reference to the flowchart of FIG.
First, when the probe 20 moves from another region to the region A1 (step S1), the position information of the probe 20 acquired by the position detection unit 25 is input to the position information acquisition unit 101. Then, the solid storage location change unit 105 sends a solid storage location change signal for changing the solid storage location to the solid sorting and holding unit 50 based on the change of the position information input from the position information acquisition unit 101. To do. As a result, in the solid sorting and holding unit 50, an actuator (not shown) is actuated to change the solid storage location (step S2). Here, as shown in FIG. No. 4 solid bottle 51 is moved so as to face the end of the solid lead-out path 41. Four bottles are set as solid objects. In this way, the solid object is No. The information indicating that the bottle is No. 4 is sent from the solid storage location changing unit 105 to the solid information storage unit 104.

  Next, water supply by the liquid supply unit 80 is started (step S3). As a result, a liquid is introduced into the cavity 21 in the probe 20, and the liquid comes into contact with the region A <b> 1 on the surface of the structure 1. Thereafter, water supply by the liquid supply unit 80 is stopped, and the water supply ends (step S4). Thereafter, the liquid is circulated between the probe 20 and the analysis unit 60 to advance the separation of the solid from the region A1 and the elution of the contaminant.

During this circulation, the solid content in the contaminated solution is captured by the solid-liquid separation unit 40, and No. 1 among the plurality of solid bottles 51 through the solid outlet 41. The solid component is accommodated in the four solid bottles 51. At this time, the solid information storage unit 104 stores the bottle information (No. 4) from the solid container changing unit 105 and the positional information (area A1) of the probe 20 in association with each other (step S5).
Thus, according to the correspondence stored in the solid-state information storage unit 104, No. It can be recognized that the solid part peeled from the region A1 is accommodated in the four solid bottles 51.
Finally, such a correspondence is displayed on the result display unit 110 (step S6). At this time, as described above, the correspondence relationship may be displayed for each region on the shape map of the structure 1 on the result display unit 110.
The correspondence relationship may be recorded not only on the result display unit 110 but also on a paper medium to be printed out.

  Next, acquisition of the contaminated solution in the region A1 will be described with reference to the flowchart of FIG. In order to facilitate the explanation, the collection of the solid component and the acquisition of the contaminated solution have been described separately, but in actuality, these are performed simultaneously. Therefore, some steps (steps S11, S12, S13, and S15) in the flowchart of FIG. 7 overlap those in the flowchart of FIG.

  First, when the probe 20 moves from another region to the region A1 (step S11), the position information of the probe 20 acquired by the position detection unit 25 is input to the position information acquisition unit 101. Then, the liquid storage location changing unit 106 sends a liquid storage location change signal for changing the storage location of the contaminated solution to the liquid sorting and holding unit 61 based on the change of the location information input from the location information acquisition unit 101. Send it out. As a result, in the liquid sorting and holding unit 61, the location for storing the contaminated solution is changed by operating an actuator (not shown) (step S12). Here, as shown in FIG. No. 4 liquid bottle 62 is moved so as to face the end of the first flow path 31. Four bottles are the target for containing the contaminated solution. In this way, the contamination solution is to be stored in No. The information that the bottle is the fourth bottle is sent from the liquid storage location changing unit 106 to the liquid information storage unit 108.

Next, water supply by the liquid supply unit 80 is started (step S13). As a result, a liquid is introduced into the cavity 21 in the probe 20, and the liquid comes into contact with the region A <b> 1 on the surface of the structure 1, so that a solid component is separated from the region A <b> 1 and a contaminant is eluted. The water supply amount by the liquid supply unit 80 is acquired by the water supply amount detection unit 90, and the water supply amount information is input to the water supply amount acquisition unit 102.
Thereafter, the water supply by the liquid supply unit 80 is stopped, and the water supply ends (step S15). Thereafter, the liquid is circulated between the probe 20 and the analysis unit 60 to advance the separation of the solid from the region A1 and the elution of the contaminant.

  Thereafter, the liquid is circulated between the probe 20 and the analysis unit 60 to advance the separation of the solid from the region A1 and the elution of the contaminant. After the liquid has been sufficiently circulated, the contaminated solution is a No. 2 liquid bottle 62 to be stored. 4 bottles. Next, the concentration detector 63 detects the concentration of the contaminated solution in the liquid bottle 62 containing the contaminated solution (step S16). This density information is input to the density acquisition unit 103.

  Next, the contamination degree calculation unit 107 calculates the contamination degree (step S17). That is, in the contamination degree calculation unit 107, the absolute amount of contaminants in the contaminated solution contained in the liquid bottle 62 based on the water supply amount information from the water supply amount acquisition unit 102 and the concentration information from the concentration acquisition unit 103. Is calculated. The absolute amount of this contaminant is a value corresponding to the degree of contamination. Here, the contamination degree calculation unit 107 corresponds to the absolute amount of contaminants.

At this time, the liquid information storage unit 108 associates the bottle information (No. 4) from the liquid storage location changing unit 106 with the positional information (area A1) of the probe 20 and the degree of contamination (absolute amount of contaminant). (Step S18).
As described above, according to the correspondence relationship stored in the liquid information storage unit 108, the No. The contaminants eluted from the area A1 are accommodated in the No. 4 solid bottle 51, and the absolute amount value (contamination value) of the contaminant can be recognized.
Finally, such a correspondence is displayed on the result display unit 110 (step S19). At this time, as described above, the correspondence relationship may be displayed for each region on the shape map of the structure 1 on the result display unit 110.
The correspondence relationship may be recorded not only on the result display unit 110 but also on a paper medium to be printed out.

  In the above, the probe 20 is located in the region A1 and solids and contaminants are acquired. However, the same process is performed in each region by sequentially scanning the probe 20. Thereby, the absolute amount of the solid content and the contaminant in each region can be acquired.

  As described above, according to the surface adhering matter detection apparatus 10 of the present embodiment, the concentration of the contaminated solution discharged from the probe 20 is analyzed by the concentration detector 63 of the analysis unit 60 to obtain the degree of contamination while obtaining the degree of contamination. The solid on the surface of the structure 1 can be collected by removing the solid from the contaminated solution by the liquid separator 40. Therefore, various information such as physical properties, life, fatigue durability, etc. of the surface of the structure 1 can be acquired by proceeding with detailed analysis afterwards for each of the eluted contaminants and the separated solids.

  Moreover, the solid content removed from the contaminated solution can be stored in association with each region. That is, since the solid content for each region on the surface of the structure 1 can be collected, information for each region of the structure 1 can be obtained by separately analyzing the solid, for example.

  Furthermore, since the contaminated solution can be held in association with each region where the contaminant is eluted into the liquid and the contaminated solution is generated, the degree of contamination for each region of the surface of the structure 1 is detected. Can do. Also by this, as described above, it becomes possible to obtain information for each region of the structure 1 by a subsequent analysis.

  The embodiment of the present invention has been described above, but the present invention is not limited to this, and can be appropriately changed without departing from the technical idea of the present invention.

  For example, the arrangement direction of the solid bottle 51 and the liquid bottle 62 in the solid sorting and holding unit 50 and the liquid sorting and holding unit 61 may be not only linear but also circular or matrix. In the embodiment, the solid bottle 51 and the liquid bottle 62 are moved by the actuator. For example, the solid outlet 41 and the first flow path 31 are connected to the plurality of solid bottles 51 and liquid bottles 62 at the ends. It is also possible to change the storage location for the solid content and the contaminated solution by moving the solid content.

In the embodiment, the liquid supply unit 80 supplies clean water. However, for example, when oil is eluted as a contaminant, a specific organic solvent may be used as the liquid.
Furthermore, the surface deposit detection apparatus 10 does not necessarily include both the solid sorting and holding unit 50 and the liquid sorting and holding unit 61, and may be configured to include either one.
