  The present invention relates to a disaster prevention simple exploration camera for exploring survivors and saving lives in the event of an accident or natural disaster.

  Various rescue devices have been developed to search for and rescue victims or victims buried in rubble, etc., in the event of an accident or natural disaster. For example, there is provided a CCD camera device for visual search as disclosed in Japanese Patent Laid-Open No. 10-83015 for visual search and confirmation of a victim buried under a collapsed building or a house at the time of the disaster. . This CCD camera device for visual search includes a telescopic grip rod having a flexible tube at the tip, and a cylindrical camera with a small CCD camera, illumination lamp, microphone, etc. built into the tip tube of the grip rod. And a control box with a built-in television receiver or the like.

Japanese Patent Laid-Open No. 10-83015

  Generally, as a necessary condition for such a rescue apparatus, the structure should be as simple as possible and easy to handle. In other words, it is preferable that it can be easily operated by simple explanation on site without receiving special training or training, and does not break even if handled somewhat roughly. Moreover, since the rescue operation may take a long time, it is necessary to continue to use the device for a long time under any circumstances.

From this point of view, the rescue device of Patent Document 1 uses a battery as a power source, but is unsuitable for exploration over a long period of time because there is a limit to the amount of electricity stored in the battery.
Further, the rescue apparatus of Patent Document 1 has no problem in that the structure is simple, but as a problem inherent to the rescue apparatus, the viewing angle is narrow with respect to the operation of the camera unit, and the operation is not easy.

  That is, in the conventional rescue apparatus, the angle of the camera unit is changed by the operation of four wires. As described above, the cylindrical camera unit is attached to the tip of a flexible tube. For this reason, it is not easy to pull a flexible tube having a restoring force with a wire and to direct the camera unit in a predetermined direction. Moreover, there is a limit to the angle at which the flexible tube can be bent, and it is difficult to bend the flexible tube by pulling the wire to greatly change the angle of the camera unit.

  The present invention has been made to solve such a problem, and has a simple structure, is easy to handle, has a wide viewing angle of a camera that can be probed, and can generate power manually without worrying about turning off the power. It aims to provide a stick camera.

  The present invention comprises a front end side exploration portion to which a camera is rotatably attached, a rear end side grasping portion provided with a reel, and a rod connecting the exploration portion and the grasping portion. The other end is wound around the reel of the gripping part via a tension spring, and the rotational force of the reel is transmitted to the camera of the searching part via a wire.

  In the above invention, the camera is rotatably attached to the exploration part, and the camera is rotated by the reel of the grip part via the wire. Thereby, the photographing angle of the camera can be changed.

  Further, the exploration bar camera of the present invention is equipped with a manual generator, and the manual generator has a flywheel that is manually rotated via a rotating shaft at an upper portion of a frame serving as a base, And a generator for generating power by transmitting the rotational force of the flywheel.

  Equipped with a manual generator, it is possible to stably supply electricity to the exploration bar camera. Moreover, since the structure is simple, the operation is easy.

  The exploration rod camera of the present invention has a simple structure, can explore the interior of the rubble at a wide angle at the time of disaster, and can perform exploration work for a long time even in a disaster site where electricity cannot be supplied.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 5 is a side view of the exploration part of the exploration stick camera, and FIG. 6 is a side view of the grasping part of the exploration stick camera.

  The exploration bar camera of this embodiment manually generates electricity on a long exploration bar camera 2 that is carried by a rescuer 1 to explore a victim or a victim buried in rubble or the like. A manual generator 5 for supplying electricity to the exploration bar camera 2 and the control box (TV monitor) 3 via a cable 4 is provided.

  The exploration bar camera 2 includes a long-distance exploration part 7 equipped with a CCD camera 6, a gripping part 8 for operating the CCD camera 6, and a long connecting part of the exploration part 7 and the grasping part 8. It is composed of a rod 9.

  As shown in FIGS. 2 and 3, the exploration unit 7 has a CCD camera 6 attached to a rotary pulley 10 attached to the tip of a rod 9 via a bracket 11. As shown in FIG. 2, the lens 6 </ b> A of the CCD camera 6 is normally directed rearward (in the direction of the grip 8) by the tension spring 12. The viewing angle of the CCD camera 6 is generally about 50 to 70 degrees. However, as will be described later, the exploration bar camera 2 can observe almost all directions.

  Although the CCD camera 6 is an existing general camera, the camera of the exploration unit 7 is not limited to the CCD camera 6 and may be of any other type as long as it can be monitored at hand. There may be. In addition to the CCD camera 6, an illumination device, a microphone, and other sensors may be provided in the exploration unit 7. Note that the tip of the exploration bar camera 2 (CCD camera 6, rotating pulley 10) is covered and protected by a protective cover 2A.

  The rotating pulley 10 has a disk shape and is provided with a pulley plate 10A on one side. A wire 13 for rotating the CCD camera 6 is in contact with the pulley plate 10A only half a circle, and one point is fixed pin 10E as described later. It is fixed with. The rotating pulley 10 is a circular thick plate having a predetermined thickness for attaching the mounting bracket 14 of the CCD camera 6, and the material may be a synthetic resin or a metal such as aluminum. As described above, the pulley plate 10A is provided with the groove 10D around the outer peripheral side edge so that the wire 13 comes into contact therewith.

  A shaft hole 10 </ b> B is formed at the center of the rotary pulley 10. The rotary shaft 10C is inserted into the shaft hole 10B, and the rotary shaft 10C is pivotally supported by the bearing portion 162A of the tip joint 16 so that the rotary pulley 10 is rotatably supported.

  As shown in FIG. 5, the mounting bracket 14 for attaching the CCD camera 6 to the rotary pulley 10 is composed of an L-shaped bracket 14A and a holding bracket 14B fixed to the side surface of the L-shaped bracket 14A with bolts and nuts. . The L-shaped bracket 14A has a bottom piece fixed to a predetermined position of the rotary pulley 10 by a bolt and a nut. That is, the L-shaped metal fitting 14A is fixed on the rotating pulley 10 by bolts and nuts. The holding bracket 14B is formed in a substantially triangular shape in plan view and a U-shape in side view, and the CCD camera 6 is mounted inside the U-shaped holding bracket 14B. The CCD camera 6 attached to the attachment bracket 14 can rotate about 180 degrees in angle with the rotation of the rotary pulley 10.

  The bracket 11 that pivotally supports the rotating pulley 10 has two parallel connection pipes 15 </ b> A and 15 </ b> B fixed by a front end joint 16 and a rear end joint 17. One of the connection pipes 15A and 15B is longer than the other, and is configured such that the tip end portion of the rod 9 is fitted into one connection pipe 15A projecting rearward from the rear end joint 17. One and the other connecting pipes 15A and 15B are cylindrical pipes, and light metal pipes such as aluminum are used.

  The tip joint 16 has a pair of upper and lower plates overlapped on the tip of one and the other connecting pipes 15A and 15B and is firmly fixed by bolts and nuts. The plate body of the tip joint 16 includes a rectangular joint portion 161A that is fixed to one and the other connection pipes 15A and 15B, and a bearing portion 162A that has a semicircular tip portion that is slightly narrower in the tip direction. It is formed in a T shape in plan view.

  A rear end joint 17 is firmly fixed by bolts and nuts on the rear end side of one and the other connecting pipes 15A and 15B. The rear end joint 17 is composed of a pair of upper and lower rectangular plates, and sandwiches one and the other connection pipes 15A and 15B from above and below, and fixes two places at the center with bolts and nuts.

  The rod 9 connected to one of the connecting pipes 15A as described above is a long pipe, which is a long pipe made of light metal such as aluminum, glass fiber, carbon rod, synthetic resin, wood. It is a long rod such as any material. Further, the rod 9 may be capable of expanding and contracting its length.

Next, the grip part 8 will be described.
The gripping part 8 is for the rescuer 1 to operate the CCD camera 6 when using the exploration stick camera 2, and the exploration part 7 is inserted into the debris of a collapsed building or the like and is handed to the rescuer 1. The angle taken by the CCD camera 6 can be changed. This gripping portion 8 has a gripping portion main body 8A that the rescuer 1 grips, and includes a connecting portion 8B for inserting the rear end portion of the rod 9 at the tip of the gripping portion main body 8A. A reel 18 around which the rear end is wound is attached. The grip portion main body 8A is made of a light metal such as aluminum or a synthetic resin pipe, and the connecting portion 8B is a pipe having a diameter larger than that of the grip portion main body 8A. A guide pulley 19 that changes the direction of the wire 13 is provided inside the grip portion main body 8A at the rear end of the grip portion main body 8A. That is, as shown in FIG. 6, the rear end portion of the gripping portion main body 8A is flattened in an elliptical shape, and a guide pulley 19 sandwiched between pulley spacers 19A from above and below is disposed therein, and the guide pulley 19 and the pulley spacer A pulley shaft 19B is inserted into and supported by 19A.

  The reel 18 may be an existing fishing reel. The reel 18 has a spool 18B in which the rear end of the wire 13 is wound around a reel frame 18A. By rotating the handle knob 18C, the spool 18B can be rotated to wind or rewind the wire 13. it can.

Next, how to stretch the wire 13 will be described.
A tension spring 12 is connected to the tip of the wire 13. The tension spring 12 is disposed in the other connection pipe 15B of the bracket 11, and the tip thereof is fixed to the connection pipe 15B (exploration part). The wire 13 is connected to the rear end of the tension spring 12, passes through the other connecting pipe 15B, makes a semicircular contact with the pulley plate 10A of the rotary pulley 10, passes through the one connecting pipe 15A and the rod 9, and further includes a gripping portion. 8, the direction is changed by the guide pulley 19 and wound around the spool 18B. Further, in the state shown in FIGS. 2 and 3, the starting end of the wire 13 on the side of the CCD camera 6 that starts to contact the pulley plate 10A is fixed by a fixing pin 10E. As a result, the rotational force of the reel 18 is directly transmitted to the pulley plate 10A via the wire 13, so that there is no slip between the wire 13 and the pulley plate 10A, and an accurate angle adjustment of the CCD camera 6 becomes possible.

  In the above embodiment, the CCD camera 6 rotates the rotating pulley 10 to change the shooting angle by operating the wire 13, but the rotating pulley 10 is not necessarily used to rotate the CCD camera 6. Alternatively, the CCD camera 6 may be rotated by attaching a camera to one end of the rotating rod and pulling the other end of the rod by the wire 13. Alternatively, the CCD camera 6 may be fixed to the center of a circular rotating plate, and the CCD camera 6 may be rotated by pulling a wire wound around the rotating shaft of the rotating plate. Thus, the mechanism for rotating the CCD camera 6 is not limited to that using the rotary pulley 10.

Next, an operation method of the exploration bar camera 2 will be described.
As shown in FIG. 1, the rescuer 1 holds the exploration stick camera 2 and inserts the exploration unit 7 of the exploration stick camera 2 into a place where exploration is necessary (for example, in a house collapsed due to the earthquake). When the hand knob 18 </ b> C of the reel 18 is operated, the wire 13 is wound around the spool 18 </ b> B, and the rotating pulley 10 is rotated by the wire 13 being dragged against the urging force of the tension spring 12. As the rotary pulley 10 rotates, the CCD camera 6 attached to the rotary pulley 10 rotates.
Assuming that the state of FIG. 2 is a state before winding the wire 13 by the reel 18, in this state, the lens 6A of the CCD camera 6 faces rearward (in the direction of the gripping portion 8) as shown in FIG. In the state shown in FIG. 5, when the probe 9 is rotated 360 degrees about the longitudinal axis of the rod 9 of the exploration bar camera 2, the rear side can be almost observed. For example, when only a small hole is opened at the entrance of a large cavity such as an old burial mound, when the exploration stick camera 2 is inserted through the small hole on the entrance side and the stick camera 2 is rotated 360 degrees in this state, the state on the entrance side Can be observed. The inside of the photographed image is displayed on the television camera in the control box 3.

  When the rear observation is finished, the wire 13 is slightly wound around the reel 18 and the rotating pulley 10 is rotated to change the photographing angle of the CCD camera 6. By changing the angle of the CCD camera 6 and rotating 360 degrees about the longitudinal axis of the rod 9 of the bar camera 2 for exploration as described above, the surroundings can be observed with the angle changed. By winding the wire 13 with the reel 18, the CCD camera 6 rotates at an angle of 180 degrees in the plan view of FIG. When this operation is combined with the rotation about the axis of the 360-degree rod 9 of the exploration bar camera 2, observation in almost all directions becomes possible. Therefore, even the CCD camera 6 with a narrow field of view can search in all directions.

  When the handle knob 18C is returned, the wire 13 is returned to the original state by the urging force of the tension spring 12, and accordingly, the rotary pulley 10 is returned to the original state, and the CCD camera 6 is also returned to the initial position in FIG. Return.

  As for the relationship between the spool 18B of the reel 18 and the pulley plate 10A, if the circumference of the spool 18B of the reel 18 and the circumference of the pulley plate 10A are the same, the handle knob can be obtained by rotating the CCD camera 6 180 degrees. The rotation angle of 18C may be rotated by 180 degrees. Thus, if the angle of the handle knob 18C and the angle of the CCD camera 6 are the same, the angle of the CCD camera 6 can be known even if the exploration part 7 is hidden in the debris, which is convenient for operation. In any case, the ratio of the size of the spool 18B of the reel 18 and the pulley plate 10A may be set so that the handle knob 18C can be easily operated.

Next, the manual generator will be described.
Since there is often no expectation of supply of electricity from a general power source at the time of a disaster, a battery is usually used as the power source of the rescue apparatus. Other than the battery, a small engine generator, a solar battery panel, and the like are conceivable. However, batteries are unsuitable for long-term exploration work, and small generators may miss the slight surviving sound of the victims due to the loud engine noise. Solar cells also have drawbacks that depend on the weather.

  Rescue generators require a reliable power supply, but they also have a simple structure, are easy to operate, and can be operated by inexperienced people, and are not affected by weather conditions, environmental conditions, etc. It is required to be able to carry out the operation, to be free of burden on the worker even for long hours of work, to be easily transported, and not to be stored.

  If you don't need a lot of power, such as when shooting with a CCD camera, a manual generator that is manually generated by humans can generate power under any conditions, and it can help multiple people. If it exists, it is preferable as a power supply of a rescue apparatus. In this embodiment, a manual generator for disasters using a flywheel is employed. In this embodiment, the device is devised so that it can be easily divided and carried and yet does not take up a storage place.

  FIG. 7 is a perspective view of a manual generator, and FIG. 8 is a side view. In this manual generator, a flywheel 21 is rotatably supported on the upper surface of a T-shaped frame 20, and a generator 22 is provided at the rear end.

  The T-shaped frame 20 has a structure in which two rod-shaped steel members 20A and 20B having a U-shaped cross section are brought into contact with a T shape and fixed by bolts and nuts. A rotating shaft 23 for attaching a flywheel 21 is attached to the T-shaped frame 20. That is, two protrusions 25 for fitting the base plate 24 of the rotating shaft 23 of the flywheel 21 are formed in parallel on the upper surface of the T-shaped vertical bar portion 20B of the T-shaped frame 20, and the two The base plate 24 is fitted between the protrusions 25 and fixed with bolts and nuts. By fixing the base plate 24, the rotating shaft 23 and the flywheel 21 are supported by the T-shaped frame 20.

  The rotary shaft 23 of the flywheel 21 has a cylindrical structure 26 in which a bearing structure (not shown) is accommodated, and a disc-shaped flange 27 is provided at the tip of the rotary shaft (not shown) of the bearing structure. It is attached. The flange 27 has a circular convex portion 27A that fits in the central hole of the flywheel 21 at the central portion, and includes a flange portion 27B in which a large number of screw holes are formed on the outer peripheral portion of the circular convex portion 27A. The inner peripheral portion of the divided piece 21A of the wheel 21 is fixed with bolts and nuts to form a wheel shape.

  The flywheel 21 has a weight of about 30-40 kilograms and rotates by inertia when it rotates. The flywheel 21 is composed of eight fan-shaped divided pieces 21A as described above, and is fixed to the flange 27 of the rotary shaft 23 and assembled into a wheel shape. A handle 29 for rotation is attached to one piece of the divided piece 21A of the flywheel 21.

Although the flywheel 21 is convenient for transportation and storage when divided, it is not always necessary to divide the flywheel 21 and may be integrated in a wheel shape.
A generator 22 is detachably attached to the rear end portion of the T-shaped vertical bar portion 20B of the T-shaped frame 20. The generator 22 is fixed to a slide plate 30 </ b> A, and the slide plate 30 </ b> A is slidably fitted in the longitudinal direction of the rear end portion of the T-shaped frame 20. The slide plate 30 has a protrusion 30 </ b> A protruding downward fitted in a long hole 31 at the rear end of the T-shaped frame 20, and slides along the long hole 31. The slide plate 30 is biased toward the flywheel 21 by a spring (not shown), and the rotating shaft 22A of the generator 22 abuts on the outer peripheral edge of the flywheel 21 by this spring. Therefore, as the flywheel 21 rotates, the rotating shaft 22A of the generator 22 rotates to generate power. With this manual generator, power can be supplied to the CCD camera 6 and the control box 3 attached to the exploration bar camera 2.
In the above embodiment, the rotating shaft 22A of the generator 22 is in contact with the outer peripheral edge of the flywheel 21 by the spring. However, the manual generator 5 of the present invention is not limited to such a configuration. For example, the structure which connects the flywheel 21 and the rotating shaft 22A of the generator 22 with a belt or a chain may be sufficient. Moreover, in order to adjust the weight of the flywheel 21, you may make it the structure which uses water, sand, gravel, etc. as a weight.

FIG. 9 is a block diagram of the power supply unit for the exploration bar camera.
The bar camera power supply 35 stores the electricity generated by the manual generator 5 in the electric double layer capacitor 36. When the electricity is stored up to a predetermined voltage in the capacitor 36, the surplus power is directly DC-DC. It can be used as a power source.

  The bar camera power supply 35 is connected to the manual generator 5 via a relay connector 37 with a cable. The manual generator 5 has a built-in rectifier circuit, and a direct current is input to the bar camera power supply unit 35.

  The bar camera power supply unit 35 is provided with an upper limit voltage cut circuit 38. The upper limit voltage cut circuit 35 cuts off the current when the voltage generated by the manual generator 5 exceeds a predetermined value (for example, 18V or more). Stop so that current does not flow to subsequent circuits. This ensures the rated input voltage of the electric double layer capacitor 36 and the subsequent DC-DC power supply circuit 40.

The current that has passed through the upper limit voltage cut circuit 38 flows through the following three routes and is used as a power source for the exploration bar camera 2 and the control box 3.
1) A route that flows from the constant current circuit 39 to the electric double layer capacitor 36 and stores electricity in the electric double layer capacitor 36. The circuit is opened and closed by the third switch (SW3).
2) A route for supplying electric power stored in the electric double layer capacitor 36 to the exploration bar camera 2 or the like via the DC-DC power supply circuit 40. The circuit is opened and closed by the second switch (SW2).
3) A route for supplying power from the upper limit voltage cut circuit 38 directly to the exploration bar camera 2 or the like via the DC-DC power supply circuit 40. The circuit is opened and closed by the first switch (SW1).

  The constant current circuit 39 reduces the manual turning of the flywheel 21 of the manual generator 5 even when the electric double layer capacitor 36 has a low potential. That is, when the electric double layer capacitor 36 is in a completely discharged state, the electric potential is 0. Therefore, when viewed from the manual generator 5, it is close to a short-circuited state, so that the handwheel of the flywheel 21 becomes very heavy and difficult to turn. Become. Even when the electric double layer capacitor 36 is empty, the manual generator 5 can be manually driven for a long time by allowing only a current that can be manually driven to flow.

  The DC-DC power supply unit 40 stabilizes a power supply voltage (for example, 12V). That is, the CCD camera 6 and the monitor 3 have stable voltage input specifications. However, if the input voltage range of the DC-DC power supply unit 40 is 9V-18V, when SW1 and SW2 are turned on and power is supplied from the manual generator 5 and the electric double layer capacitor 36, 9V A varying voltage in the range of −18 V is supplied to the DC-DC power supply unit 40. For this reason, the DC-DC power supply unit 40 serves to stabilize the power supply voltage to 12V.

  The various voltage / current monitoring circuits 41 turn on and off the first switch (SW1), the second switch (SW2), and the third switch (SW3), and control the current flowing through the three routes. A current meter 42 and a voltage meter 43 are connected to the various voltage / current monitoring circuits 41, and the rescuer 1 can monitor the current and voltage of the manual generator 5. Each switch (SW1), (SW2), and (SW3) has two N-channel MOS transistors arranged in series, but the switch is not necessarily limited to such a configuration.

Hereinafter, a method of controlling the switches (SW1) (SW2) (SW3) by the various voltage / current monitoring circuits 41 will be described with reference to the flowchart of FIG.
Step 1 (S1): The handle 29 of the manual generator 5 is turned to start power generation. The power generation method can be achieved simply by turning the handle 29 of the flywheel 21 and the operation is quite simple. The generated alternating current is rectified by the rectifier in the generator 5 and flows to the power source unit 35 for the bar camera. When the upper limit voltage of the manual generator 5 is high, the upper limit voltage cut circuit 38 of the power source unit 35 for the bar camera is cut as described above.

  Step 2 (S2): If the electricity generated by the manual generator 5 is lower than the predetermined voltage (18V) of the upper limit voltage cut circuit 38, various voltage / current monitoring circuits 41 are switched so as to store electricity in the electric double layer capacitor 36. (SW1) (SW2) (SW3) are controlled. That is, when the switches (SW1) and (SW2) are turned off and the switch (SW3) is turned on, the current generated by the manual generator 5 flows through the upper limit voltage cut circuit 38 and the constant current circuit 39, and the switch The electric double layer capacitor 36 flows through (SW3). The electric power is stored until the electric double layer capacitor 36 reaches a predetermined voltage (for example, 15 V).

  Step 3 (S3): When the electric double layer capacitor 36 rises to a predetermined voltage (15V), the switches (SW1) and (SW2) are turned on, and (SW3) is turned off. When the switches (SW1), (SW2), and (SW3) are switched in this way, since (SW2) is ON, the exploration bar camera 2 and the like from the electric double layer capacitor 36 through the DC-DC power supply circuit 40, etc. Can be powered. In addition, power can be directly supplied from the upper limit voltage cut circuit 38 directly to the exploration bar camera 2 or the like through the DC-DC power supply circuit 40.

  Step 4 (S4): Since power for operating the exploration stick camera 2 etc. has been secured in the above step 3, the exploration of the victim is started by operating the exploration stick camera 2 etc. The method of this operation is as described above.

  Step 5 (S5): Since the electric power stored in the electric double layer capacitor 36 is consumed by the operation of the exploration bar camera 2 or the like, the voltage of the electric double layer capacitor 36 becomes lower than a predetermined voltage. At that time, the process returns to step 2, and the switches (SW1) and (SW2) are turned off and the switch (SW3) is turned on to store electricity in the electric double layer capacitor.

  Step 6 (S6), Step 7 (S7); The electric power stored in the electric double layer capacitor 36 in Step 5 is still sufficient, or there is a sufficient supply of electricity from the manual generator 5, and the capacitor 36 When the search can be continued, the switch (SW1) (SW2) is on and the switch (SW3) is off and the search is continued.

  Step 8 (S8): When the exploration is finished, the manual generator 5 is stopped. The electricity stored in the electric double layer capacitor 36 is discharged, and the electricity in the capacitor 36 becomes zero.

  The present invention provides a bar camera for exploration that can be used for lifesaving in a disaster, and that can perform exploration work even in a disaster site that can be reliably operated with a simple structure and cannot receive power supply. be able to.
