A weight 25 is attached to the lower end of 15. The weight 25 is used to prevent the camera 41 from wobbling. The weight of the weight 25 is, for example, about 360 to 380 g.

  In detail, the first and second snapped salkans 17 and 23 are often used for fishing, for example, as shown in FIG. 1 (b). It is possible to connect a metal fitting having a snap-type, and attach and connect each wire to each of the ring-shaped portions.

  Further, as shown in FIG. 1A, a cylindrical camera 41 is attached to a portion near the lower end portion of the second wire 19 of the wire 20 configured as described above, for example, a mounting member 43 such as a vinyl tape. Attach and fix it so that it is tied. Similarly, the camera cord 47 extending upward from the camera 41 is also fixedly attached so as to bind the second wire 19 with an attachment member 45 such as a vinyl tape.

  The wire and camera 41 shown in FIG. 1 (a) are attached to the wire 20, inserted into the hollow portion 5 of the concrete electric pole 1, and already hung down to the lower end portion. In this state, the camera 41 can be attached to the second wire 19 and the wire 20 with the weight 25 at the lower end is attached to the camera in this state. A pipe 13 made of aluminum or the like into which the third wire 23 is inserted in order to hang down at about the center of the cylindrical cross section of the hollow portion 5 together with 41 is an opening 7 formed in the outer peripheral portion 3 of the concrete utility pole 1. Is inserted horizontally, and one end of the pipe 13 extends to the center of the cylindrical shape in the hollow portion 5 of the concrete electric pole 1, and the other end extends to the outside of the concrete electric pole 1. Together are illustrated as the third wire 23 to the pipe 13 is inserted, the tip of the third wire 23 extends to the outside through the pipe 13.

  Further, in the state shown in FIG. 1A, the weight 25 attached to the lower end portion of the wire 20 stands up against the earth and sand 31 at the lowermost end portion of the concrete electric pole 1 and is attached to the second wire 19. The camera 41 is hung down to the lower end portion of the hollow portion 5 together with the wire, and a lower image in the hollow portion 5 can be taken by an imaging lens attached downward of the camera 41. The camera cord 47 that extends from the upper end of the camera 41 and is attached to the second wire 19 with the attachment member 45 includes the second wire 19, the second snapped salkan 23, the third wire 23, and the pipe 13.

Specifically, the water sensor that extends downward immediately before the camera 41 is hung down together with the wire in the hollow portion 5 and is immersed in, for example, the retained water 33 existing in the lower end portion of the hollow portion 5. When 41a detects the retained water 33, the fact is displayed on the monitor 49 via the camera 41 and the camera code 47, thereby preventing the camera 41 from being immersed in the retained water 33 by mistake.

  Next, a series of confirmation operation procedures for confirming in advance the internal state of the concrete power pole 1 before the construction of the concrete power pole interior confirmation method of the present embodiment described above will be described. It is assumed that the opening 7 has already been formed by using the ground hole or the like.

  As shown in FIG. 1 (a), in order to conduct an investigation to confirm in advance the standing state of the concrete utility pole 1 standing in the ground 11, particularly the interior of the hollow portion 5, first the first wire 15, the second wire 19 and the third wire 23 are connected with the first snapped salkan 17 and the third wire 23 as shown in FIG. A weight 25 is attached to the lower end of the wire 20, that is, the lower end of the first wire 15.

  Next, the camera 41 is fixedly attached to the lower end portion of the second wire 19 with an attachment member 43 such as a vinyl tape, and the camera cord 47 connected to the upper end portion of the camera 41 is also an attachment member such as a vinyl tape. Install fixedly at 45. In this case, the imaging lens attached to the tip of the camera 41 where the CCD camera 41b is exposed, that is, the lower end of the camera 41 in FIG. 1A, is attached to face the weight 25.

  As described above, the wire 20 with the weight 25 is prepared, the camera 41 and the camera cord 47 are attached to the wire 20, and then the upper end of the wire 20, that is, the tip of the third wire 23 is inserted into the pipe 13. Then, the camera cord 47 is placed along the wire 20 and the pipe 13.

  Next, the weight 25 is inserted into the hollow portion 5 from the opening 7 of the concrete utility pole 1, and then the wire 20 is also inserted into the hollow portion 5 from the first wire 15. When the first wire 15 is completely inserted into the hollow portion 5 from the opening 7, the camera 41 attached to the second wire 19 is positioned at the opening 7. 41 is also inserted into the hollow portion 5 through the opening 7 together with the wire 20. Subsequently, the wire 20 and the camera cord 47 provided along each other are inserted into the hollow portion 5 through the opening 7 so as to be sequentially taken out together. Note that the wire 20 and the camera cord 47 are fed into the hollow portion 5 so that both are pulled by the weight 25 attached to the lower end portion of the wire 20.

  Thus, the position where the weight 25 is attached to the lower end portion, the wire 20 to which the camera 41 is attached, and the camera cord 47 are sequentially fed downward into the hollow portion 5 and the wire 20 is inserted into the pipe 13. Is located at the opening 7, the pipe 13 is inserted into the hollow portion 5 from the opening 7, and the tip of the pipe 13 is set so as to be located at the approximate center of the cross section of the hollow portion 5. Set to maintain.

  When the tip of the pipe 13 is set so as to be positioned at the approximate center of the cross section of the hollow portion 5, the wire 20 hanging downward from the tip of the pipe 13 is pulled and tensioned by the gravity of the weight 25, It is stretched straight and vertically toward the bottom of the lowermost end of the concrete utility pole 1. In this case, the weight 25 attached to the lower end portion of the wire 20 is slightly swayed at first, but is finally located substantially at the center of the cross section of the hollow portion 5.

  In this way, the wire 20 hangs straight down due to the gravity of the weight 25, but when the weight 25 does not reach the bottom of the concrete utility pole 1, until the weight 25 reaches the bottom of the concrete utility pole 1, When the wire 20 is further fed into the hollow portion 5 through the pipe 13, the camera cord 47 is also fed into the hollow portion 5 through the opening portion 7 along with the feeding of the wire 20 along the wire 20.

  Thus, when the operation | movement which draws out the wire 20 and the camera cord 47 in the hollow part 5 is performed continuously, the weight 25 attached to the lower end part of the wire 20 will hit the bottom of the concrete utility pole 1, and FIG. ), The weight 25 lies one side down. When the weight 25 hits the bottom of the concrete utility pole 1 and falls on its side, the tension of the wire 20 is loosened. Therefore, the tension of the wire 20 is maintained on the side that has been fed out through the pipe 13 while holding the upper end of the wire 20. By detecting the looseness, it can be known that the weight 25 has reached the bottom of the concrete utility pole 1. On the side where the upper end of the wire 20 is held and the wire 20 is fed through the pipe 13, the wire 20 may be held and fed by an operator or mechanically. In addition, the operator can detect the looseness of the tension of the wire 20 or can be automatically performed by the apparatus.

  As described above, when it is detected that the weight 25 has reached the bottom of the concrete utility pole 1 and has been laid down by detecting the looseness of the tension of the wire 20, as shown in FIG. In order to raise the weight 25, the wire 20 extending from the pipe 13, FIG. 1A pulls the third wire 23 so as to be taken out from the hollow portion 5 through the pipe 13.

  In this way, when the weight 25 stands up, the wire 20 is pulled and tensioned again, and is fixed in a state where the tension is maintained between the weight 25 and the tip of the pipe 13, and the wire 20 swings and staggers as in the conventional case. Also disappear. As a result, the camera 41 attached to the wire 20 by the attachment member 43 is not shaken and fluctuated. Therefore, a clear image can be obtained by imaging the inside of the hollow portion 5 of the concrete electric pole 1 with the camera 41 in this state.

  In the above-described processing of the present embodiment, the first wire 15, the second wire 19, and the third wire 23 are connected in advance by the first snapped salkan 17 and the second snapped salkan 23, and the wire 20 is prepared, and the weight 25, the camera 41, and the camera cord 47 are attached to the wire 20 in advance, and the confirmation work by the camera 41 can be quickly performed. Even if not, the first wire 15, the second wire 19, and the third wire 23 are simply connected by the first snapped salkan 17 and the second snapped salkan 23 to form the wire 20. Since only the work of attaching the weight 25, the camera 41, and the camera cord 47 to 20 is more than the conventional work, and this work is relatively simple, To wander camera 41 is swinging, was by the camera 41 to be able to shorten dramatically the work time compared to conventional working time it took to imaging is complete. Specifically, the work time that has conventionally taken 1 hour can be reduced to, for example, about 10 minutes.

  In the above description, the weight 25 reaches the bottom of the concrete electric pole 1 and the weight 25 that has been laid down is raised, and then the inside of the hollow portion 5 is imaged by the camera 41. While not being limited, while the wire 20 is tensioned by the gravity of the weight 25 and the camera 41 is being fed downward together with the wire 20, each lower position in the hollow portion 5 is moved by the camera 41 moving downward. It goes without saying that the imaging in may be performed a plurality of times as appropriate. Also in this case, the wire 20 to which the camera 41 is attached is pulled downward by the weight 25 and is strained, so that there is no wobbling of the wire 20 and the camera 41, and the image in the hollow portion 5 is quickly displayed by the camera 41. Can be imaged.

  Furthermore, in the above embodiment, the case where the camera 41 is fixedly attached to the wire 20 with the attachment member 43 has been described. However, the present invention is not limited to this, and as described above, the camera 41 is provided. First, the wire 20 is hung down and tensioned using the weight 25 without being fixedly attached to the wire 20, and then only the camera 41 is rearranged along the wire 20 in the tensioned state using the weight 25. An annular member such as a ring having a diameter slightly larger than the diameter of the wire 20 is attached to the camera 41, and the camera 41 is connected to the wire 20 by inserting and connecting the wire 20 to the annular member. In this loosely connected state, the camera 41 is moved downward along the wire 20 in the hollow portion 5 using the annular member, or in some cases While moving back towards the inside of the hollow portion 5 of the concrete electric pole 1 by imaging by the camera 41 is intended to be confirmed.
