It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The first embodiment is as follows: as shown in fig. 1 and 8, which are only one embodiment of the present invention, a water barrier structure for facilitating escape comprises a plurality of water barrier door panels 100, a pair of door panel slideways 300, and a chain driving mechanism 200 for driving the water barrier door panels 100 to move, wherein the water barrier door panels 100 comprise a main body panel 110, a first positioning portion 120 located at the upper end of the main body panel 110, and a first positioning groove 130 for connecting with the first positioning portion 120 of an adjacent main body panel 110, the chain driving mechanism 200 comprises a driving sprocket and a door panel chain engaged with the driving sprocket, the main body panel 110 comprises a plurality of first door panels 111 and a plurality of second door panels 112, the first door panels 111 and the second door panels 112 are connected with the door panel chain through roller shafts 210, the distance between the roller shafts 210 on two adjacent first door panels 111 is smaller than the distance between the roller shafts 210 on the first door panels 111 and the roller shafts 210 on the second door panels 112, the door panel slide 300 is provided with a fixing assembly 400 for fixing the first door panel 111.

In the utility model, a top box body is arranged at the top of the entrance, a chain driving mechanism 200 and a power mechanism are arranged in the top box body, a pair of chain driving mechanisms 200 are arranged at two sides of the top box body, a pair of guide rails for supporting the water-retaining door plate piece 100 to be hung in a row are also arranged in the top box body, and the guide rails are used for supporting the water-retaining door plate piece 100 to be hung vertically. Compare in prior art, with water-stop door plate 100 direct fixed mounting in the lower extreme of shutter door, the height of water-stop door plate 100 this moment is greater than the meter at least, and when the shutter door rose to the top, water-stop door plate 100 still occupied great space, was unfavorable for the pedestrian to pass through. Therefore, a plurality of water-blocking door plates 100 are vertically hung on the guide rail, so that the water-blocking door plates 100 occupy small space and are convenient to store. The chain driving mechanism 200 includes a driving sprocket and a door chain engaged with the driving sprocket, roller shafts 210 are disposed on two sides of the water-blocking door panel 100, and the water-blocking door panels 100 are connected to the door chain through the roller shafts. Taking the height of the water gate plate 100 as 25 cm as an example, the distance between the roller shafts 210 on two adjacent water gate plate 100 needs to be greater than 25 cm, and the distance between the roller shafts on two adjacent water gate plate 100 is preferably 28 cm, so as to prevent the two adjacent water gate plate 100 from colliding or interfering in the process of ascending or descending, which may result in the water gate plate 100 not being able to ascend or descend normally.
