[0071] In a further embodiment of the present invention, an electric control box is also included for controlling the lifting motor 61 and the locking motor 71.

[0072] In a further embodiment of the present invention, sealing strips are provided around the upper door panel 4 and around the lower door panel 5, so that the upper door panel 4 and the crossbeam 3, the upper door panel 4 and the left column 1 and the right column 2, the upper door panel 4 and the lower door panel 5, the lower door panel 5 and the left column 1 and the right column 2, and the lower door panel 5 and the ground can all be in a sealed state.

[0073] In a further embodiment of the present invention, a single span is 8 meters and the water retaining height is more than 2 meters. Multiple intelligent folding water retaining doors can be combined and connected to achieve a larger span.

[0074] The working method of the present invention is described below:

[0075] Step 1: Start the electric control box, the locking motor 71 rotates to drive the first lever 72, which is transmitted to the second lever 74 and the third lever 77 by the first connecting rod 73 to rotate, the second lever 74 drives the second connecting rod 75 to make the upper locking piece 76 translate and unlock, and the third lever 77 drives the third connecting rod 78 to make the middle locking piece 79 translate and unlock.

[0076] Step 2: After unlocking, the rotating shaft of the lifting motor 61 rotates, driving the transmission gear 62 to rotate, driving the lifting chain 65 and the tensioning sprocket 64 to rotate, and the lifting seat 66 on the lifting shaft 67 of the lower door panel 5 moves up and down following the lifting chain 65. The lifting shaft 67 descends in the side column guide grooves of the left column 1 and the right column 2 along with the lifting chain 65. After the lower door panel 5 falls to the ground, the lifting motor 61 stops, and the upper door panel 4 and the lower door panel 5 stop moving.

[0077] Step 3: Start the locking motor 71 again. The locking motor 71 rotates in the opposite direction to drive the first lever 72, which is transmitted to the second lever 74 and the third lever 77 by the first connecting rod 73 to rotate in the opposite direction. The second lever 74 drives the second connecting rod 75 to make the upper locking plate 76 translate and lock. The third lever 77 drives the third connecting rod 78 to make the middle locking plate 79 translate and lock.

[0078] Step 4: During the locking process, the upper door panel 4 and the lower door panel 5 are pressed against the left column 1 and the right column 2, and the sealing strips of the upper door panel 4 and the lower door panel 5 fit the sides of the left column 1 and the right column 2 to achieve sealing. When the upper door panel 4 and the lower door panel 5 are changed from angles to planes, the bottom sealing strip of the lower door panel 5 will press the bottom surface, and the left column 1, the right column 2 and the bottom surface will form a U-shaped sealing surface to achieve the purpose of blocking water flow.

[0079] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
