The limiting driving unit 621 may be a motor, which may be rotated forward or backward.

Thus, since the bi-directional threaded rod 622 has two threaded surfaces with opposite rotation directions, the two L-shaped plates 623 respectively disposed on the two threaded surfaces can move in opposite directions or backward directions in the third direction c under the action of the limiting driving unit 621, i.e., the L-shaped plates 623 can move in the third direction c along the bottom of the fixing frame 12. The two L-shaped plates 623 move to drive the corresponding limiting plates 611 to move along with the corresponding limiting plates, and finally, the limiting rods 612 on the limiting plates 611 move in the third direction c in opposite directions to be inserted into the corresponding limiting grooves 221, or the limiting rods 612 move in the third direction c in opposite directions to be pulled out of the corresponding limiting grooves 221.

The second catch 354 is restricted from being separated from the catch groove 231 by the catch elastic member 355. When the second buckle 354 is snapped into the card slot 231, the buckle elastic member 355 is in an initial state, and when the second buckle 354 is required to be disengaged from the card slot 231, the buckle elastic member 355 needs to be stretched against the elasticity of the buckle elastic member 355.

The principle of operation of the flood control roller door 100 is:

When the flood control roller shutter door 100 needs to block flood, firstly, the roller shutter driving mechanism drives the wind-up roller 21 to rotate, so that the door piece 222 of the roller shutter door body 22 is unfolded to move downwards along the second direction b, meanwhile, the bottom baffle plate 23 moves downwards along with the roller shutter door body 22 along the second direction b until the transmission rack 33 on the bottom baffle plate 23 is meshed with the transmission gear 34 along with the movement, the transmission gear 34 rotates clockwise so as to enable the transmission rod 31 to rotate along with the movement, and the transmission rod 31 drives the buckling piece 35 to rotate clockwise again, so that the buckling piece 35 is buckled into the buckling groove 231 to limit the movement of the bottom baffle plate 23, and at the moment, the roller shutter door body 22 is completely unfolded into a door. Secondly, in order to enhance the protection of the two sides of the rolling door body 22, the two-way threaded rod 622 is driven to rotate by the limit driving unit 621, so that the two L-shaped plates 623 move to drive the corresponding limit plates 611 to move in opposite directions, and finally the limit rods 612 on the limit plates 611 move in opposite directions along the third direction c to be inserted into the corresponding limit grooves 221. Finally, to enhance the protection of the lower portion of the rolling shutter body 22, the shutter device 5, i.e. the telescopic rod 41, is opened to extend along the first direction a, the second rotating rod 53 rotates clockwise, the shutter assembly 51 moves upward in the second direction b in the chute 133 to protrude from the bottom plate 132, and the driving rod 31 rotates clockwise in the whole process, so that the fastening member 35 is further fastened into the fastening slot 231, and the limitation of the bottom shutter 23 is enhanced.

When the flood control roller shutter door 100 needs to be opened, the protection on both sides of the roller shutter door body 22 is firstly released, that is, the two-way threaded rod 622 is driven to rotate by the limit driving unit 621, so that the two L-shaped plates 623 move to drive the corresponding limit plates 611 to move back along with the corresponding limit plates, and finally the limit rods 612 on the limit plates 611 move back along the third direction c to pull out the corresponding limit grooves 221. Secondly, the restriction of the baffle device 5 and the bottom baffle 23 is released, that is, the telescopic rod 41 is contracted along the first direction a, the second rotating rod 53 rotates anticlockwise, the baffle assembly 51 moves upwards along the second direction b in the chute 133 to be hidden in the bottom plate 132, and the transmission rod 31 rotates anticlockwise in the whole process, so that the clamping piece 35 is separated from the clamping groove 231, and the restriction of the bottom baffle 23 is released. Finally, the rolling roller 21 is driven to rotate by the rolling shutter driving mechanism, so that the door piece 222 of the rolling shutter door body 22 is rolled up to move upwards along the second direction b, meanwhile, the bottom baffle 23 moves upwards along the second direction b along with the rolling shutter door body 22, the transmission rack 33 on the bottom baffle 23 is meshed with the transmission gear 34 along with the movement in the process, the transmission gear 34 rotates anticlockwise, so that the transmission rod 31 rotates anticlockwise, the transmission rod 31 drives the clamping piece 35 to rotate anticlockwise, the clamping piece 35 is further separated from the clamping groove 231, and the limitation on the bottom baffle 23 is cancelled. Thereby, as the rolling shutter body 22 rises, the flood control rolling shutter 100 is opened.
