     Refer to  FIGS. 6A, 6B, 6C and 6D , which are a solid appearance view, a solid combination schematic view, a solid combination schematic view from another lateral viewing angle and a plan combination schematic view from the top viewing angle showing the automatic auto-sensing flood protection roller shutter with auto-locating reinforced column according to a preferred embodiment of the invention. As shown in the figures, a door plate fixation hole  113  of said door leave  11  (as shown in  FIG. 4 ) is inserted with one end of a first axis shaft  12 , the other end of which drills said chain  46  and sheathes a bearing set  13 ; the guide wheel anchor block  115  of said door panels  11  is locked up with a guide wheel fixation plate  14 , which is sheathed with a guide wheel  15 . 
     Refer to  FIGS. 7A, 7B, 7C and 7D , which are a first, a second, a third and a fourth lateral operation views showing access of a plurality of door panels of the automatic auto-sensing flood protection roller shutter with auto-locating reinforced column to a casing. As shown in the figures, the opening of said branch rail  43  is provided with a guiding opening  44  expanding outwards, as a plurality of door panels  11  desired to be overlapped in a line to form a waterproof shutter are folded in the storage device  4  of the casing  2 , the gear  45  may be driven by the motor  21  to rotate at first for the chain  46  to move towards the storage device  4  under the driving of the gear  45 , such that a plurality of door panels  11  overlapped originally may move along with the guide rail  42  sequentially towards the storage device  4  as the chain  46  contained in the guide rail  42  moves, while at the same time the bearing set  13  of one end of a plurality of door panels  11  connected pivotally to the chain  46  moves as the chain  46  moves, as one end, having the guide wheel  15 , of a plurality of door panels  11  moves to the intersection formed by connecting the branch rail  43  and the guide rail  42 , it may be diverged by a projection at the intersection to move along with the branch rail  43  towards the storage device  4 , such that a plurality of said door panels  11  may be separated actually as the gear  45  moves towards the overhead rail  41 , and the inclination of the overhead rail  41  may be used for the bearing set  13  to moves towards the overhead rail  41  smoothly and suspended on the overhead rail  41  to complete that the storage device  4  disposes and folds a plurality of door panels  11  automatically to achieve the advantages of convenient containment and facilitate to use. 
     On the contrary, as a plurality of door panels  11  in the casing  2  are desired to move external to the storage device  4 , the motor  21  may be used to drive the gear  45  to rotate at first for the chain  46  to move sequentially from the overhead rail  41  to the guide rail  42  under the driving of the gear  45 , such that a plurality of door panels  11  aligned together originally moves external to the storage device  4  sequentially along with the guide rail  42  as the chain  46  in the guide rail  42  moves, while at the same time the bearing set  13  of a plurality of said door panels  11  moves as the chain  46 , the guiding of the guide wheel  15  at the guiding opening  44  is adapted further to move downwards in the branch rail  43 , for a plurality of said door panels to be in an overlapping shape under the driving of the guide rail  42  and the chain  46 , such that a plurality of door panels  11  are disposed in the frames  3  to form a waterproof shutter. Therefore, with the design of above bearing set  13 , guide rail  42  and branch rail  43 , the rocking and inclined movement may be avoided as a plurality of door panels are raised and lowered to achieve the advantages for stable movement and reduction of equipment damage. 
     Moreover, two stoppers  47  are provided in the storage device  4  to stop a plurality of said door panels  11 . With the design of stoppers  47 , the occurrence of damage of a plurality of door panels caused by collision may be reduced to achieve the advantages for protection of door panel  11  structure and increase of door panel  11  life. Besides, because a certain gap exists wherever the chain  46  is connected pivotally with each of a plurality of door panels  11 , as a plurality of said door panels  11  moves inwards to or outwards from the casing  2  along with the chain  46 , a plurality of said door panels  11  may overlap mutually by the hand clamping prevention block piece  111  (as shown in  FIG. 4 ) provided therewith. Therefore, there is no separation between a plurality of door panels  11  to achieve the advantage for safe operation of waterproof and flood protection. Also, as shown in  FIGS. 7E-1, 7E-2, 7F-1 and 7F-2 , which show a schematic view of an appearance for a fixation board of a storage device in a preferred embodiment of the invention, a schematic view of an enlarged appearance of  FIG. 7E-1 , a schematic view of an appearance for a chain guard board of the storage device and a schematic view of an enlarged view of  FIG. 7F-1 , wherein the overhead rail  41  of the storage device  4  is provided with a fixation board  481  and a chain guard board  482  thereon, the fixation board  481  allows the overhead rail  41  to form a fixed space, such that the bearing set  13  and the door panel  11  may move along with the overhead rail  41  more stably and freely without deflection from the overhead rail  41 . Further, the chain guard board  482  may prevent links of the chain  46  from getting constricted and stuck tightly as the door panel  11  is shut, closed such that the door panel  11  is not raised, lowered smoothly. Hence, the additional installment of the chain guard board  482  achieves the advantage that the chain  46  is forced to be spread as the door panel  11  is lowered for the door panels  11  to be raised, lowered more smoothly. Besides, As shown in  FIGS. 7G-1 and 7G-2 , which are schematic views showing the appearance for two of the folding portions of the overhead rail of the storage device, wherein the upper edge and the lower edge of the overhead rail  41  of the storage device  4  are disposed with a folding portion  411 , respectively, an internal space formed by the overhead rail  41  and the two folding portions  411  contains the flange  131  of the bearing set  13 . With the installment of the folding portion  411  and the flange  131 , the bearing set  13  may slide within the overhead rail  41  more stably to achieve the advantage that the bearing set  13  is kept from being detached and that the bearing set  13  is contained within the overhead rail  41 . 
     Refer to  FIG. 8 , which is a lateral operation view showing a downward-pressing hydraulic cylinder of the automatic auto-sensing flood protection roller shutter with auto-locating reinforced column according to a preferred embodiment of the invention. As shown in the figure, after a plurality of door panels  11  are lowered and pushed horizontally for layers to be aligned and fit, the downward-pressing hydraulic cylinder  5  is pressed downwards for the downward-pressing plate  51  to press a plurality of door panels  11  with sealing gasket  118  disposed between each panel downwards to be waterproof to achieve the advantages for increase of airtight and waterproof and disaster prevention. 
     Refer to  FIG. 9 , which is a lateral operation view showing a sideward-pressing hydraulic cylinder of the automatic auto-sensing flood protection roller shutter with auto-locating reinforced column according to a preferred embodiment of the invention. As shown in the figure, after a plurality of door panels  11  are lowered and pushed horizontally for layers to be aligned and fit, the downward-pressing hydraulic cylinder  5  is pressed downwards for the downward-pressing plate  51  to press a plurality of door panels  11  with sealing gasket  118  disposes between each panel downwards to be waterproof (as shown in  FIG. 8 ), subsequently, the sideward-pressing hydraulic cylinder  6  presses downwards to drive the push lever  61  to induce the stop lever  62  to lower, as the stop lever  62  is lowered to a horizontal angle, the pressing plate  63  is stopped to push horizontally a plurality of door panels  11  for the waterproof glue strip  1172  to be more tight and fit therewith, such that the advantages for increase of airtight and waterproof and disaster prevention are achieved.
