POWERLESS AUTOMATIC DESCENT GATE AT TIME OF EARTHQUAKE
To provide a powerless automatic descent gate at the time of an earthquake that can be installed at low cost and can automatically shut off waterways without power supply in the event of an earthquake of a predetermined scale or larger.SOLUTION: A powerless automatic descent gate 1 at the time of an earthquake includes a door body 2 that shuts off a waterway H by descent, a powerless seismic sensing device 6, and a door body holding mechanism K that normally holds the door body 2 in a standby position that does not shut off the waterway H and allows the door body 2 to descend in the event of an earthquake of a predetermined scale or larger. The powerless seismic sensing device 6 includes a pedestal 61 and a ball 62 mounted so as to fall off the pedestal 61 in the event of an earthquake of a predetermined scale or larger. The door body holding mechanism K includes a ratchet mechanism 5 connected via the ball 62 and a first wire 8, an interlocking weight 4 connected via the ratchet mechanism 5 and a second wire 9, and a lifting pin mechanism 3. The lifting pin mechanism 3 normally holds the door body 2 in a standby position, and releases the holding of the door body 2 when the interlocking weight 4 that has fallen in conjunction with the fall of the ball 62 collides in the event of the earthquake.SELECTED DRAWING: Figure 1
【課題】安価で設置可能で、所定規模以上の地震発生時に無電源で自動的に水路を遮断できる地震時無電力自動降下ゲートを提供する。【解決手段】地震時無電力自動降下ゲート１は、降下により水路Ｈを遮断する扉体２と、無電源感震装置６と、常態で扉体２を、水路Ｈを遮断しない待機位置に保持し、所定規模以上の地震発生時には、扉体２の降下を許容する扉体保持機構Ｋとを備える。無電源感震装置６は、台座６１と、所定規模以上の地震発生時に台座６１から脱落するように載置された球６２とを備える。扉体保持機構Ｋは、球６２と第１ワイヤ８を介して連結されるラチェット機構５と、ラチェット機構５と第２ワイヤ９を介して連結される連動ウエイト４と、リフティングピン機構３とを備える。リフティングピン機構３は、常態で扉体２を待機位置に保持し、上記地震発生時に球６２の脱落に連動して落下した連動ウエイト４が衝突すると、扉体２の保持を解除する。【選択図】図１
