Next, how to use the disaster prevention endoscope system and its effects will be explained. As shown in FIG. 1, for example, when a house 2 is buried in earth and sand 1 that has collapsed due to heavy rain, the disaster victim 3 is unable to get out because the entrance is blocked.

If Victim 3 is trapped like this for a long time, he will collapse from exhaustion and starvation due to lack of food. This state cannot be seen from the outside, and even if you shout, it will not reach the outside. If left in this state, it will lead to death and the loss of precious human life. Therefore, before such a situation arises, it is necessary to check whether there are any trapped people and to know what the internal situation is in order to take effective rescue methods. Moreover, it is necessary to perform this search quickly and accurately.

Therefore, this endoscope system for disaster prevention will be used. First, the earth and sand are
Proceed through the moat while cutting through obstacles such as buildings and houses. That is, the rotational force transmission device 14 is connected to the rear connector 45 of the guide tube 4 for hole plate. At this time, the connection is made using a connection part 47 consisting of a flat surface 48 on the outer periphery of the rear end of the rear connector 45. Then, the rotational force is transmitted from the rotational force transmission device 14 to the hole plate guide tube 4. For this reason,
As the hole plate guide tube 4 rotates, it advances through the trench while scraping obstacles such as earth and sand 1 and houses 2 with the cutting edge 15 of the cutting tip 33 at its tip. In addition, the hole plate guide tube 4 and the rotational force transmission device 14 are connected to an O ring 49.
Since the rotational force transmission device 14 is connected watertightly,
A suction machine (vacuum) provided on the side sucks and removes the earth and sand 1 etc. that have entered the inside of the hole plate guide tube 4. The guide tube 4 for the perforated plate can also be used for air and water supply, and can be used, for example, to replenish oxygen in an oxygen-deficient state or to blow away sewage or the like.

In this embodiment, the hole plate guide tube 4 is integrated and rotated as a whole, but the tip drilling tip 33 is made rotatable, and the high pressure air is blown out with a compressor or the like. The tip excavation tip 13 may also be rotated.

When the tip of the hole plate guide tube 4 penetrates into the house 2 where the disaster victim 3 is located, the rear connector 45 of the hole plate guide tube 4 is separated from the rotational force transmission device 14 and the rear connector 45 is removed. It is supported by the first pillar 16. That is, the rear connector 45 of the guide tube 4 for hole plate 4 is supported by the supporting portion 108 of the hook 106 while the column shaft 101 and the locking portion 107 of the hook 106 are respectively engaged with the pair of left and right engaging recesses 46 . Incidentally, once the position of the rear connector 45 of the hole plate guide tube 4 has been determined, the first support 16 is erected by driving it into the ground with a hammer or the like in accordance with the position.

Further, the height of the hook 106 can be arbitrarily selected by selecting the square hole 105. Therefore, the hole plate guide tube 4 can be introduced and installed into the house 2 filled with earth and sand 1, and the endoscope 5 can be inserted into the hole plate guide tube 4 as described later. An insertion path 7 for inserting the part 6 can be secured. .

Once the insertion path 7 has been secured in this way, the guide tube 8 with the sensor is inserted and penetrated through the insertion path 7. A soft sealing rubber 13 is fitted over the middle of the rear end of the guide tube 8 with the sensor, and the opening on the rear end of the hole plate guide tube 4 is closed with the soft sealing rubber 13 after penetration.

Furthermore, the insertion section 6 of the endoscope 5 is inserted into this guide tube 8 with a sensor. Note that the tip of the guide tube 8 equipped with a sensor is closed with a dirt prevention stopper 59, so that dirt from outside does not enter. However, since it is provided with a slit, the endoscope 5.

The insertion portion 6 can be easily penetrated.

Furthermore, when the sensor-equipped guide tube 8 or the insertion section 6 of the endoscope 5 is inserted in this way, air and water are supplied using the cleaning port 51. As described above, the opening on the rear end side of the hole plate guide tube 4 is closed with the soft seal rubber 13. In addition, the cleaning opening 5
It is also possible to inspect gas by suctioning the atmosphere on the tip side of the hole plate guide tube 4 through the hole plate guide tube 1 .

Further, at the distal end of the guide tube 8 with a sensor, the outer periphery of the distal end fitting 57 attached to the distal end portion of the distal end main body 56 is formed into a tapered shape with a narrow distal end, and this serves as an insertion guide surface 60. When the guide tube 8 with this sensor is inserted into the hole plate guide tube 4, it can be inserted easily and quickly without getting stuck.

On the other hand, an endoscope 5 is fixed to the rear end of the guide tube 8 with a sensor. That is, the folding tube 87 is inserted into the cylindrical fixed tube 82 inside the rear main body 74, but the
Since the inner surface of the end of the fixed tube 82 is tapered, it can be easily inserted along the gently sloped surface.

Then, it is located inside the four engaging pieces 83. Each of the engaging pieces 83 has an inner surface that is inclined so as to spread outward, but the tightening force for threading the proximal end portion of the rear main body 74 can be reduced by the tapered portion 85 of the engaging piece 83 by screwing in the ring 84. At the same time, the protrusion 86 at the protruding tip of each engagement piece 83 fits into and engages the engagement groove 89 in the support fitting 88 for fixing the folding tube.

Thereby, the guide tube 8 with sensor and the endoscope 5 are fixed. The light guide cable 23 of the endoscope 5 is connected to an illumination light source 26 and receives illumination light from the illumination light source 26.

Furthermore, the proximal operation part 9 of the endoscope 5 is placed on the endoscope holder 125 of the second support post 18 which is set up on the ground in the same way as the first support support 16, and fixed with the fixing band 128. do. Therefore, the endoscope 5 can be operated and observed from the eyepiece 19 without having to take the trouble to support the hand-held operating section 9 of the endoscope 5 with one's hands. Furthermore, when observing on the TV monitor 28, the TV left camera 7 is attached to the eyepiece 19 of the endoscope 5 via the photographing adapter 20. This TV left camera 7 is fixed to a camera holder 131 using a fixing screw 136. Then, the photographed signal is sent to the video device 25 through the cord 21, and the screen is displayed on the TV monitor 28. Also, this video is recorded on the video cassette recorder 2 of the video device 25.
You can record on 7.

Furthermore, the sound and temperature inside the house 2 are detected by a microphone 68 and a temperature sensor 69 provided at the tip of the sensor-equipped guide tube 8. Then, this detection signal is input through the cord 70 to circuits such as amplifiers for audio signals and sensor signals on the circuit board 92, and is electrically processed. This processed electrical signal is code 9
5 and socket 96, and further this socket 9
The signal is inputted to a detection device (not shown) installed in a portable video device 25 through a signal transmission cable 22 connected to the port 6. Then, the sound is generated by the speaker 29, and the temperature information a is displayed at the lower right corner of the screen of the TV monitor 28, as shown in FIG.

Therefore, by using this endoscope system for disaster prevention, it is possible to confirm whether the disaster victim 3 is alive and to understand the situation in which the disaster victim 3 is trapped.

Furthermore, if an ultra-small speaker is installed at the tip of the sensor-equipped guide tube 8, it is possible to use this to inform the disaster victims of the rescue situation and to give them encouragement to cheer them up.

In addition, in the configuration of the above embodiment, the guide tube 8 with sensor
Although only a microphone 68 and a temperature sensor 69 are provided as detection sensors at the tip of the sensor, detection sensors with other functions may be provided instead of or in addition to these. For example, a gas concentration sensor for oxygen, carbon dioxide, city gas, propane gas, etc., a humidity sensor, etc. may be attached. If these are also included, it will be possible to know the situation more accurately. This information is also displayed on the TV monitor 28 as shown in Figure 11.

This second embodiment is for the case where the portable video device 25 etc. cannot be brought to the disaster site.
As shown in FIG. 12, this is a system used to directly visually observe the eyepiece 19 of the endoscope 5. That is,
A port-a-pull alarm device 143 that can be hung on the shoulder of an operator 142 using a belt 141 is prepared, and this port-a-pull alarm device 143 is equipped with various sensors, such as a voice input microphone, provided at the tip of a guide tube 8 with a sensor. 144-1, temperature detection microphone 144-2
