PROBLEM TO BE SOLVED: To provide a waterproof door closing device free of defects seen in a conventional technique that various kinds of power sources are adopted in many of existing waterproof door opening and closing devices, and a structure or a function of operation is complicated, emergency operation under a hostile environment such as in occurence of a disaster or a storm causes risks, and the device may become inoperative by a sudden accident such as a power failure in remote control operation.SOLUTION: In a mechanism for automatically closing a waterproof door 2 by shifting a pulling implement 10 or a hanging implement 9 with a linking function between a pulley device 3 and a power source generation device, swollen water flows from an opening of the power source generation device, and when mass on an inflow water vessel 5 reaches prescribed gravity, the gravity is imparted to a rotation force assisting drum so as to make assistance, rotation movement of the pulley is facilitated, and the inflow water vessel is lowered, and the waterproof door in linkage also starts closing action. Accordingly, a power source is naturally generated, and therefore, manual operation is unnecessary, and in order to prevent the waterproof door from going out of control, an opening closing lid 17 or an air flow restricting implement 20 is provided, and speed of the waterproof door is controlled.
【課題】既存の多くの防水扉の開閉装置は種々の動力源を採用しているが、構造や操作の機能が複雑であったり、或いは災害の発生時や暴風等の悪環境下での緊急操作は危険が伴ったり、又、遠隔操作では停電などの突発事故で操作不能に陥ることがある。それらの欠点がない防水扉閉鎖装置を提供する。【解決手段】滑車装置３と動力源発生装置との連係機能で引っ張り要具１０や吊り下げ要具９を変移させて防水扉２を自動的に閉鎖する機構で、動力源発生装置の開口部から増水が流入し、流入水容器５上の質量が一定の重力に達すると回転力補助用ドラムに重力を与えて補助し滑車の回転動作を容易にして流入水容器を降下させて連係の防水扉も閉鎖運動を開始する。従って動力源は自然的に発生するので人手の操作は不要であり、また、防水扉の暴走を防止する為、開口部閉鎖用の蓋１７や空気流量制限器具２０等を設けて防水扉の速度を制御している。【選択図】図２
