Automatic auto-sensing flood protection roller shutter with auto-locating reinforced column

An auto-sensing flood protection roller shutter with auto-locating reinforced column, including:

• a door plate, which is composed of a plurality of door panels, which are movable between two frames mounted on two sides of the door plate from a position in which the door plate is stored in a storage device to an extended flood protection position;
• a casing of the storage device, which is provided above the door plate and is provided with a motor, a hydraulic pump, an automatic controller, a power system, at least one downward-pressing hydraulic cylinder and a driving device in an interior of the casing of the storage device;
• overhead rails extending in a horizontal direction between left and right inner walls of the storage device and guide rails extending in a vertical direction at each end of the overhead rails, one end of each of the guide rails being bonded respectively with a connecting branch rail, a gear being provided at respective connections between the overhead rails and the guide rails, a chain being engaged with each of the gears, and the chain being movable along the overhead rails and each of the guide rails to lower the door plate from storage in the storage device to the extended flood protection position;
• the at least one downward-pressing hydraulic cylinder, which is provided in said casing, a downward-pressing plate being provided at a lower end of the hydraulic cylinder to press the door plate downwardly when the door plate is in the extended flood protection position;
• at least one sideward-pressing hydraulic cylinder, which is provided in one of said frames, a push lever being connected to a lower end of the sideward-pressing cylinder;
• a water level detector, which is provided in an underground space for a waterproof system to be turned on automatically once a certain water level is detected;
• at least one reinforced column, which is provided behind the door plate, and a reinforced column driving motor to drive the reinforced column for movement relative to the door plate via a guiding screw and transmission shaft from a first non-reinforcing position to a door plate reinforcing position when the door plate is in the extended flood protection position, and a chamber at a lower end of the reinforced column being provided with a bolt and a bolt-driving motor for vertically driving the bolt into a retaining base to secure the reinforced column at the door plate reinforcing position;
• and
• wherein the reinforced column driving motor is provided in the driving device provided at a lower portion of the casing of the storage device, a fixation joint and a bearing set being provided at each of the two inner walls of the casing of the storage device, two ends of a guiding rod being fixed respectively in said two fixation joints, one end of the guiding screw and one end of the transmission shaft being fixed in said two bearing sets, wherein another end of said guiding screw and another end of said transmission shaft are mutually coupled.
