Description

【考案の詳細な説明】 本考案は地震発生時に於ける、燃料用ガス、工業用有害
ガス等の二次災害を少なくする為になされたものである
。[Detailed Description of the Invention] The present invention was made in order to reduce secondary disasters caused by fuel gas, industrial harmful gas, etc. in the event of an earthquake.

燃料用ガスを例に上げれば、従来地震による二次災害の
火災に対し、防止用の器具等あまり実用化されていなか
った様に思われる。Taking fuel gas as an example, it seems that conventional equipment has not been put into practical use to prevent fires from secondary disasters caused by earthquakes.

例えば、大地震発生時、火災の防止は使用中の各ガス器
具のコック又は元コックを手で閉じるより方法はなかっ
たし、ゴムホース、配管等の破損によるガスの噴出もボ
ンベの元コックを手で操作し、止めるしかなかった。For example, in the event of a major earthquake, the only way to prevent a fire was to manually close the cock or main cock of each gas appliance in use, and to prevent gas from blowing out due to damage to rubber hoses, piping, etc., manually close the main cock of the cylinder. I had no choice but to operate it and stop it.

この様な恐慌状態に、屋外のボンベ又は、供給源のコッ
クを操作出来る余裕はないと思うし、使用中のガス器具
から離れて居る場合もあるので、そのコックさえ操作出
来るか疑問である。In such a state of panic, I don't think I have the luxury of being able to operate the outdoor cylinder or gas supply cock, and since I may be far away from the gas appliance in use, I doubt whether I will even be able to operate the cock.

そこで本考案は、これらの操作を自動的、且つ瞬間的に
、ボンベ又は供給源に最も近い１カ所で行われる様に考
案された装置である。The present invention is therefore a device designed to perform these operations automatically and instantaneously at one location closest to the cylinder or supply source.

図面について説明すれば、地震が発生すると、その震動
は、感度調節ネジ３に接続された永久磁石２を組込んだ
半球体１に伝わり、第２西の矢印１４の様に揺れる。To explain the drawings, when an earthquake occurs, the vibration is transmitted to the hemisphere 1 incorporating the permanent magnet 2 connected to the sensitivity adjustment screw 3, and shakes as shown by the second west arrow 14.

その瞬間、隔壁板６がある為、永久磁石２と鉄片５を埋
め込んだ栓４との間隔が大きくなり、磁力の影響が小さ
くなった栓４は第２図の矢印１５の方向に移り、受は止
め孔７で受けられ、その周囲のゴム１０に、ガスの送圧
で密着する。At that moment, due to the presence of the partition plate 6, the gap between the permanent magnet 2 and the plug 4 in which the iron piece 5 is embedded increases, and the plug 4, which is less affected by the magnetic force, moves in the direction of the arrow 15 in FIG. is received in the stopper hole 7, and is brought into close contact with the surrounding rubber 10 by the pressure of the gas.

これでカス出口１２から各器具へのガスの供給は完全に
止まる。This completely stops the supply of gas from the waste outlet 12 to each appliance.

その後、装置全体に震動が加えられたり、半球体１が正
常な位置に回復してもボンベ又は供給源より送られて来
るガス１１の圧力により、栓４は受は止め孔γの周囲の
ゴム１０に押されているので、はずれて各器具にガスが
送られる事はない。Thereafter, even if vibrations are applied to the entire device or the hemisphere 1 is restored to its normal position, the stopper 4 will not stop the stopper hole γ due to the pressure of the gas 11 sent from the cylinder or supply source. Since it is pressed to 10, it will not come off and send gas to each appliance.

又繰返し装置をセットする場合は、本装置を水平にし、
ボンベ又は供給源の元コックを閉じ、ガス圧抜コック８
を開き、半球体１が転落したり、それに何かが触れて作
動するのを防ぐカバー９をはずし、半球体１を正常な位
置に戻すと、鉄片５を埋め込まれた栓４は、半球体１に
組込まれた永久磁石２の磁力により隔壁板６まで引上げ
られる。In addition, when setting up a repeating device, place the device horizontally and
Close the main cock of the cylinder or supply source, and turn off the gas pressure release cock 8.
When the hemisphere 1 is opened and the cover 9 that prevents the hemisphere 1 from falling or something touching it is removed and the hemisphere 1 is returned to its normal position, the stopper 4 in which the iron piece 5 is embedded is inserted into the hemisphere. It is pulled up to the partition plate 6 by the magnetic force of the permanent magnet 2 incorporated in the partition wall plate 1.

その後、ガス圧抜コック８を閉じボンベ又は供給源のコ
ックを開けばガス出口１２より各器具の方向１３にガス
１ｄ流れ、カバー９を取付ければセット完了である。Thereafter, when the gas pressure release cock 8 is closed and the cock of the cylinder or supply source is opened, the gas 1d flows from the gas outlet 12 in the direction 13 of each appliance, and when the cover 9 is attached, the set is completed.

電池、ゼンマイ等の動力源も不用であり構造が簡単なの
で故障も少ない。There is no need for power sources such as batteries or springs, and the structure is simple, so failures are rare.

尚、栓４の作動を円滑にする為、隔壁板６と一体形成す
る材質は磁気化を防ぐ為に非磁性体とし、震度の強弱に
よる作動の調節は感度調節ネジ３を回し、永久磁石２の
上下の移動によって行う。In order to make the operation of the stopper 4 smooth, the material integrally formed with the partition wall plate 6 is made of a non-magnetic material to prevent magnetization.The operation can be adjusted depending on the strength of the seismic intensity by turning the sensitivity adjustment screw 3 and adjusting the permanent magnet 2. This is done by moving up and down.
