【考案の詳細な説明】 〔産業上の利用分野〕 この考案は，地滑りや雪崩の前兆現象としての地圧変動
を敏感にキャッチする地崩れ予知センサーに関するもの
である。[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a landslide prediction sensor that sensitively catches fluctuations in ground pressure as a precursory phenomenon of landslides and avalanches.
地崩れや雪崩は，これが起こる前に必ずその崩壊方向に
地圧の増大や土砂の微小移動があるといわれている。し
たがって、この現象を察知することで，地滑り等を前も
って知ることができる。Before a landslide or avalanche occurs, it is said that there is always an increase in ground pressure and a slight movement of sediment in the direction of landslide. Therefore, by detecting this phenomenon, landslides and the like can be known in advance.
このため、地圧の増大（変動）を検出するための検出セ
ンサーが開発されるているが、従来のこの種センサーは
金属製歪ゲージや半導体歪ゲージを用いるものであった
ため、一定方向の，しかも，きわめて狭い範囲でしか検
出できなかった。したがって，広い範囲に亘って検出し
ようとすれば，非常に大きな規模のものを必要としてい
た。さらに，電源を常に必要とするから，省エネという
面でも問題があった。For this reason, a detection sensor for detecting an increase (fluctuation) in ground pressure has been developed, but since this type of conventional sensor uses a metal strain gauge or a semiconductor strain gauge, Moreover, it could be detected only in an extremely narrow range. Therefore, in order to detect over a wide range, a very large scale was required. Furthermore, since it always requires a power source, there was a problem in terms of energy saving.
この考案は，このような課題を解決するために案出され
たものであって，その目的とする処は，簡単な構造のも
のでありながら，省エネ効果を奏し，しかも，広範囲の
地圧変動を確実にキャッチできるセンサーの現出にあ
る。The present invention has been devised to solve such a problem, and the purpose thereof is to have an energy-saving effect while having a simple structure, and yet have a wide range of ground pressure fluctuations. There is a sensor that can reliably catch.
すなわち，考案は,360度全方位からの外力を受けること
で当該部分が変形する高分子材料からなる軟弾性筒体の
内部に近接スイッチを設けるとともに，この近接スイッ
チを囲包して金属箔を取り付け，前記軟弾性筒体の変形

をオンオフしてなる地崩れ予知センサーを提供したもの
である。That is, the device is provided with a proximity switch inside a soft elastic cylinder made of a polymer material that is deformed by an external force from all directions in 360 degrees, and surrounds the proximity switch with a metal foil. The present invention provides a landslide prediction sensor in which an output circuit is turned on and off by mounting and operating the proximity switch based on deformation of the soft elastic cylinder.
以上の手段をとることにより，軟弾性筒体は360°いず
れの方向からの外力を受けても当該部分が同じように変
形するから，この変形を近接スイッチでキャッチできる
のである。そして，この場合，電力は近接スイッチが働
いたときのみに消費される。By adopting the above means, the soft elastic cylinder body is deformed in the same manner even when an external force is applied from any direction of 360 °, and this deformation can be caught by the proximity switch. And in this case, power is consumed only when the proximity switch is activated.
以下，この考案の実施例を図面を参照して説明する。 An embodiment of the present invention will be described below with reference to the drawings.
第１図はこのセンサーの断面図であるが，ゴムやプラス
チック等の高分子材料で構成される内部が空間の円筒形
をした軟弾性筒体１を用意し，これを地圧変動を知ろう
とする地面下２のなかに埋める。なお，ここで，軟弾性
筒体１としたのは地面下２のわずかな地圧変動もキャッ
チするためである。Fig. 1 is a cross-sectional view of this sensor. To prepare a soft elastic cylinder 1 made of a polymer material such as rubber or plastic and having a cylindrical interior with a hollow space Fill it in the bottom 2 of the ground. The soft elastic cylinder 1 is used here to catch a slight fluctuation of the ground pressure under the ground 2.
次に，この軟弾性筒体１の内部適所に近接スイッチ３を
設けるとともに，この近接スイッチ３を囲包するよう感
知片である金属箔４を取り付けるのである。なお，この
例では近接スイッチ３は一つのみ設けてあるが，これを
複数個，複数段に取り付けてもよい。さらに，これを囲
包する金属箔４であるが，取り付けの容易性を考慮する
限り，軟弾性筒体１の外周に貼着し，その外周を収縮性
の保護チューブ５で覆って熱収縮させたものが好ましい
が，この他に軟弾性筒体１の内周に貼着するもの，内部
に埋設するもの等種々のものが考えられる。ただ，この
金属箔４の厚みはあまり厚いと軟弾性体１の変形を阻害
するし，また，あまり薄いと破損等が起こるから，一般
的に0.03〜0.15mm程度，好ましくは0.05〜0.10mm程度が
適当であろう。Next, the proximity switch 3 is provided at an appropriate place inside the soft elastic cylinder 1, and the metal foil 4 as a sensing piece is attached so as to surround the proximity switch 3. Although only one proximity switch 3 is provided in this example, a plurality of proximity switches 3 may be mounted in multiple stages. Further, the metal foil 4 which surrounds the metal foil 4 is attached to the outer circumference of the soft elastic cylinder 1 and covered with a shrinkable protective tube 5 so that the metal foil 4 is heat-shrinked as long as the ease of mounting is taken into consideration. However, in addition to this, various ones such as one attached to the inner periphery of the soft elastic cylindrical body 1 and one embedded in the inside are conceivable. However, if the thickness of the metal foil 4 is too thick, the deformation of the soft elastic body 1 is hindered, and if it is too thin, damage or the like occurs, so generally about 0.03 to 0.15 mm, preferably about 0.05 to 0.10 mm. Would be appropriate.
第２図はこの予知センサーの回路図であるが，近接スイ

ンプ等の適当な出力回路７を直列に接続しておく。な
お，これら予知センサーは地圧変動をキャッチしようと
する個所に適当に散在させておき，電源回路６や出力回
路７は一括して集中配置するのが通常である。FIG. 2 is a circuit diagram of this predictive sensor. A power supply circuit 6 and an appropriate output circuit 7 such as an alarm or a warning lamp are connected in series to the proximity switch 3. It should be noted that these predictive sensors are normally scattered in places where it is desired to catch fluctuations in ground pressure, and the power supply circuit 6 and the output circuit 7 are usually collectively arranged in a centralized manner.
以上により，地滑りや雪崩等の前兆として地面下２に傾
斜方向に地圧の増大があれば，軟弾性筒体１が変形する
から，それに伴って金属箔４が近接スイッチ３に接近
し，そのスイッチ回路が閉じて出力回路７を作動させる
のである。From the above, if there is an increase in the ground pressure in the inclining direction under the ground 2 as a sign of a landslide, an avalanche, etc., the soft elastic cylinder 1 is deformed, and accordingly the metal foil 4 approaches the proximity switch 3, The switch circuit is closed and the output circuit 7 is activated.
以上，この考案は前記したものであるから，次のような
効果が期待できる。As described above, since the present invention has been described above, the following effects can be expected.
ｉ）地圧変動は近接スイッチ３が設けられている軟弾性
筒体１に対して360°いずれの方向からのものであって
もキャッチできるから，全方位の地圧変動を検出でき
る。i) Since the ground pressure fluctuation can be caught from any direction of 360 ° with respect to the soft elastic cylinder 1 provided with the proximity switch 3, it is possible to detect the ground pressure fluctuation in all directions.
ii）電源電力が消費されるのは近接スイッチ３が作動し
たときのみであるから，省エネ的である。ii) Power is consumed only when the proximity switch 3 is activated, which is energy saving.
iii）電源と近接スイッチ３の距離は長くてもよいか
ら，軟弾性筒体１の長さに制限を受けない。iii) Since the distance between the power source and the proximity switch 3 may be long, the length of the soft elastic cylinder 1 is not limited.
