This is a plurality of (three in the illustrated example) single rods (P1) (P2) that gradually become thinner toward the tip as shown in FIG. ) (P3) is fitted in a connected state that can be expanded and contracted via joints (J1) and (J2), and can be held by one worker (O) (approximately in the example shown in the figure). 5m maximum length). Of course, the thickness of the joints (J1) and (J2) also changes step by step in accordance with the adjacent pairs of single rods (P1), (P2), and (P3).

  Moreover, the single rods (P1), (P2), and (P3) that form the telescopic work pole (P) are impregnated with a thermosetting resin such as a phenol resin or an epoxy resin in an FRP cloth such as a glass fiber cloth or a carbon fiber cloth. The prepreg is used as a raw material, and the FRP cross prepreg is heat-cured to produce a single piece of the same constant length that has been piped into a laminated state of several plies. As a stopper flange (59), the thickness is partially increased.

  The telescopic work pole (P) is made of such a single FRP composite product (P1) (P2) (P3), so there is no risk of rusting or bending deformation, and it has both durability and light weight. . As long as such a characteristic can be exhibited, a plurality of the single rods (P1), (P2), and (P3) are piped into a laminated state having a circular cross section corresponding to each other, and a joint (J1) as if it is a swing-out type fishing rod. (J2) can be finished to a telescopic work pole (P) that cannot be seen from the outside. However, in the illustrated embodiment, a plurality of single poles (P1), (P2), and (P3) are as shown in FIGS. The pipes are formed in a laminated state having regular polygonal sections corresponding to each other, and these are connected to the thin first single rod (P1) on the distal end side thereof as a telescopic work pole (P) which does not idle relatively. The directionality of the video camera (2) is maintained in a regulated state in which the operator (O) can correctly grasp from the thick third unit (P3) on the hand side.

  Reference numeral (60) denotes a lock pin locking hole formed in the first single rod (P1) on the distal end side, and the camera unit (C) is inserted into the leg tube (C) into the first single rod (P1). 29), the lock pin (34) of the insertion leg tube (29) is received and locked in the locking hole (60), and the camera unit (C) and the telescopic work pole (P) As a result, the connection state is fixed and maintained. (61) is a blind cap made of synthetic resin which is attached and integrated with the third single rod (P3) on the hand side.

  The joints (J1) and (J2) interposed between adjacent ones of the first to third single rods (P1), (P2) and (P3) are fixed cores made of high strength synthetic resin such as ABS resin as shown in FIG. It consists of a cylinder (A) and an operation sheath cylinder (B) also made of synthetic resin.

  That is, in the middle portion of the inner peripheral surface of the fixed core cylinder (A), it can be locked to both the tip of the thick single rod (P2) side and the stopper flange (59) of the thin single rod (P1) side. A locking step (62) is provided, and about half of the proximal side with the locking step (62) as a boundary is an insertion leg tube (63), leading to the tip of the thick single rod (P2) side It is inserted and fixed in the state of fitting as shown in FIGS.

  The remaining half of the fixed core cylinder (A) that protrudes from the tip of the thick single-piece (P2) side is shaped into a thick tapered cone slope surface (64) that gradually increases in thickness toward the tip. Moreover, it is branched into a radially symmetrical arrangement type as a plurality of thin single-piece holding pieces (66) by notches in the aperture-shrinking dividing groove (65).

  In that case, the inner peripheral surface of the holding piece (66) has an overall regular polygonal cross section, and an anti-slip elastic lining (67) on the thin single rod (P2) side is attached and integrated here. ing. Similarly, the tapered cone slope surface (64), which forms the outer peripheral surface of the holding piece (66), is a guide groove rail for an operation sheath cylinder having a constant depth that gradually increases toward the tip side ( 68) are notched and arranged as an arc locus having a large curvature radius that gently continues from the lowest point (G1) to the highest point (G2).

  On the other hand, the operation sheath cylinder (B) has a cylindrical shape of a fixed length substantially corresponding to the thin single-piece holding piece (66) of the fixed core cylinder (A), and the insertion leg of the fixed core cylinder (A). It is in an assembled state in which it is inserted into the tube portion (63) in advance and fitted. Therefore, if the operation sheath cylinder (B) is pushed forward along the cylinder core line of the fixed core cylinder (A), the embedding provided with the tapered cone slope surface (64) of the fixed core cylinder (A). The holding piece (66) is contracted by the caliber and is crimped to the outer peripheral surface on the narrow straight plate (P1) side.

  (69) is a ball receiving concave groove that is notched and recessed in the inner peripheral surface of the operation sheath cylinder (B) as a relationship facing the guide groove rail (68) for the operation sheath cylinder of the fixed core cylinder (A). A steel ball (70) is inserted between the ball receiving concave groove (60) and the guide groove rail (68) in an enclosed state.

  Therefore, when performing telescopic operation of the telescopic telescopic work pole (P), the operation sheath (B) of the joint (J1) (J2) is pulled back to the root end of the fixed core (A). Then, the thin single rod (P1) is extended and extended from the thick single rod (P2) toward the distal end, and the thin single rod holding piece (66) of the fixed core tube (A) is thin. It will be in the state which surrounds the outer peripheral surface of the (P1) side.

  Accordingly, the guide groove rail (68) in which the steel ball (79) is notched in the tapered cone slope surface (64) of the holding piece (66) while holding the fixed core cylinder (A) with one hand. Along the arc trajectory, the twisting operation is performed by a certain angle (θ) while pushing forward from the lowest point (G1) to the highest point (G).

  Then, the thin single-piece holding piece (66) of the fixed core cylinder (A) is gradually contracted and deformed as shown in FIGS. 17 to 21 by the inner peripheral surface of the operation sheath cylinder (B). When the steel ball (70) reaches the highest point (G2) of the guide groove rail (68), the result is that the steel ball (70) is clamped and locked to the outer peripheral surface on the thin single rod (P1) side.

  In addition, the operation sheath (B) in the tightening lock state on the thin single rod (P1) side is also twisted and rotated in the opposite direction to the above operation with one hand, and toward the base side of the fixed core (A). When pulled back, the steel ball (70) descends to the lowest point (G1) of the guide groove rail (68) as shown in FIGS. 15 and 16, so that the tightening lock state can be instantly released, and the telescopic work pole (P) can be shortened to the state shown in FIG. 12 in which the first to third single ridges (P1), (P2), and (P3) are systematically polymerized.

  The remote inspection work device of the present invention has the above-described configuration, and when used, the insertion leg tube (29) of the camera unit (C) is attached to the thin first unit on the distal end side of the telescopic work pole (P). Plug in (P1). At that time, it is preferable to keep the telescopic work pole (P) in a shortened state.

  When the insertion leg tube (29) is inserted into the first single rod (P1), the lock pin (34) once sinking against the urging force is used for the lock pin of the first single rod (P1). As soon as it matches and matches the locking hole (60), the camera unit (C) and the telescopic work pole (P) come off because they advance into the receiving and locking state in the locking hole (60). It is connected and integrated in the stopped state.

  On the other hand, the waist bag (41) in which the receiving unit (R) is accommodated is wrapped around the waist of the operator (O), and the arm belt (55) in which the live monitor unit (M) is held is attached. Similarly, it is wound around one arm of the operator (O) and the video camera power on / off switch (17) of the power control box (12) in the camera unit (C) is turned on.

  When the inspection location is dark or at night, the power on / off switch (18) for the white LED of the power operation box (12) is also turned on. In any case, after the operation is finished, the power operation box (12) The slide cover (26) is slid to cover the power on / off switches (17) and (18) in a blinded state.

  The receiver unit (R) and the live monitor unit (M) are also kept on with the power switch turned on, and the telescopic work pole (P) that is tightened and locked in the extended state to reach the inspection point is used. The operator (O) causes the inspection head (1) of the camera unit (C) to face the inspection position by the flexible metal spiral tube (10), and the inspection position is detected by the video camera (2). Shoot.

  In this regard, FIG. 22 shows the state of the rooftop inspection of the building, but not only the height of the building, but also the ceiling, under the floor, the back of the bridge, the bottom of the vehicle, the spider's honeycomb, other visual inspections, collapsed The present invention can also be widely used for searching and rescue of people buried in buildings.

  In any case, the video taken during the work can be viewed in real time on the liquid crystal screen (46) of the live monitor unit (M), and the necessary video can be recorded on the hard disk, played back, and indoors. It can also be transferred to other computers.

  In particular, since a CMOS image sensor is employed as the imaging element of the video camera (2), unlike a CCD camera, for example, a subject such as a light source is photographed, or a metal having high reflectivity by a white LED (7) or the like. Even if it is illuminated, a clear image without smear can be obtained.

  In addition, the use of a CMOS image sensor can reduce the size and power consumption of the power supply and reduce the size and weight of the camera unit (C), which makes the telescopic work pole (P) durable. Combined with the strength and light weight of the FRP composite product, there is an effect that the inspection work for a long time can be performed lightly.

  Furthermore, since the receiver (37) forming the receiving unit (R) has four receiving channels, a total of four different video signals can be received from the two video cameras (2). When a rescue operation is performed, there is also a convenience that a plurality of workers (O) can communicate with each other and confirm each other's images to effectively promote the rescue operation.

  When the inspection work by using the remote inspection work device is completed, the telescopic work pole (P) is shortened to a certain length of the single unit (P1) (P2) (P3), and the camera unit (C) The power on / off switch (17) for the video camera and the power on / off switch (18) for the white LED in the power operation box (12) are turned off. (29) is extracted and disassembled from the first single rod (P1) on the distal end side of the telescopic work pole (P).

  The power switch of the receiving unit (R) and the live monitor unit (M) is also turned off, and the waist bag (41) and the arm belt (55) are removed from the waist and one arm of the operator (O), and still The receiving unit (R) stored in the waist bag (41), the live monitor unit (M) held in the arm belt (55), the camera unit (C), and the telescopic work pole in the shortened state Speaking of (P), as a disassembled component of the present invention, it is stored and stored in a well-positioned shoulder bag or hand-held portable bag (71) as shown in FIG.
