BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retractable water shut-off device for preventing flooding or flooding of buildings, structures, roads, etc. due to water overflowing due to high tides or floods.

[0002]

2. Description of the Related Art For example, water flooded from a river due to a heavy rain causes a bridge connection (entrance / exit) to be lower than a bank.
Inflow through the roads and flood the roads. Water flooded on the road due to flooding from rivers and storm surges flows into the underground facility through the entrance and exit leading to the road and is inundated.

Therefore, as a measure for preventing flooding and inundation, work is carried out in which sandbags are piled up at the lower part where the inflow is likely to occur and the entrance of the facility.

[0004]

When the sandbag is used as described above, the preparatory work and the installation work of the sandbag are hard work, and a time margin is required.

Although it is conceivable to install a water shut-off door at the entrance and exit, the volume and weight of the door are large, and a large storage space for storing the door is required at normal times, and it is large for opening and closing the door. Power is often required.

An object of the present invention is to solve the above-mentioned problems and to provide a retractable water shut-off door device which requires no storage space and requires a small opening / closing power.

[0007]

In order to achieve the above object, the invention according to claim 1 is a pair of guide bodies standing upright on both sides of a water blocking surface, and a storage buried in a road surface between the guide bodies. Axis parallel to the water stop surface and the road surface between the chamber and the storage posture in which the storage chamber is stored in the storage chamber in a substantially horizontal state, and the use posture in which the guide is substantially upright between the guides corresponding to the water stop surface. It is provided with a water stop door which is openable and closable around the arcuate direction, and a door guide means which is formed over the guide body and the storage chamber and guides the water stop door during the opening and closing movement.

According to the above construction, when the storage position is horizontally stored in the storage chamber and the storage position is moved to the substantially upright use position in the closing direction, the water shut door is moved along the arc direction centering on the opening / closing axis. As it is lifted by changing from a substantially horizontal state to a standing state, it can be easily started even if the driving force is small, and it can be lifted from the horizontal direction to the use posture by applying momentum. Therefore, even a manual shut-off door of a certain size can be easily handled, and for example, the base end of the shut-off door can be manually rotated around the horizontal axis from the laid state to the standing state. Compared to the conventional water shut door that opens and closes, a large and heavy water shut door can be opened and closed.

Further, since the water shut-off door is accommodated in a horizontal state in a storage room buried on the road surface, a storage place is unnecessary, and for example, a conventional water shut-off door which is rotated around a vertical axis to open and close. In comparison, it can be made compact.

According to a second aspect of the present invention, in the structure according to the first aspect, the door guide means is formed along the arc direction on one of the inner side portion of the guide body and the storage chamber and the left and right side portions of the water shut door. And a guided member that is provided on the other side and guided by the guide recess, and an opening / closing synchronization mechanism that synchronizes the opening and closing movements of the left and right side portions of the water shutoff door with each other is provided. The lock mechanism is provided to lock the water stop door.
