Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof device provided at the entrances and exits of a building, an underground parking lot, and a subway yard in order to prevent water from entering the building.

[0002]

BACKGROUND OF THE INVENTION In recent years, in urban areas, water damage due to flooding of rivers, particularly inundation of buildings, often causes great damage, and countermeasures against such damage have become an important issue.
At present, as a waterproof device for preventing water from entering the inside of a building, a waterproof device driven by a hydraulic mechanism to close the entrance of the building is mainly used.

As is well known, this device supplies pressure oil obtained by an electric pump to a cylinder, thereby driving a waterproof door. And since it can obtain a large driving force, it has the feature that it can be opened and closed regardless of the size of the waterproof door, but since the motor and pump occupy a large volume, the underfloor space is limited. It is difficult to install it in a high place, and it takes a lot of time and effort to install it.

On the other hand, a device has been proposed in which the driving force of an electric motor is converted into a linear driving force by using a crank mechanism or a jack-up mechanism using a trapezoidal screw without using a hydraulic mechanism, thereby opening and closing a waterproof door. However, in general, an electric mechanism cannot obtain such a large driving force, and thus is not suitable for opening and closing a heavy-weight and large-sized waterproof door. Moreover, the same thing can be said about the hydraulic type, but since it is basically electric drive, it is weak against water, and in an emergency situation where a waterproof door must be used, the device body will be flooded. However, in the event of a power failure, a small waterproof door can be barely used by manual operation, but a heavy one cannot be used, and there is a great reliability problem.
