The water baffle 12 is made of transparent polycarbonate material, enabling people behind the flood control wall to observe the water level change after the flood control device is installed and avoiding line of sight obstruction; at the same time, the polycarbonate material has good strength and can withstand the impact of sand and gravel in the water flow.

[0043] Embodiment 4

[0044] On the basis of the above Embodiment 3, a connecting plate 15 is provided at the top of the frame 11 of the present utility model. The connecting plate 15 is fixedly connected to the tops of the side wall plates of the frame 11 through fixing bolts 17.

[0058] When the utility model is in use, the water baffle 12 is slidably connected to the corresponding T-shaped grooves 13 on the left and right end walls of the frame 11 through the T-shaped blocks 14. Then the connecting plate 15 is installed on the frame 11, and the connecting plate 15 is fixed to the frame 11 through the groove body 16, thus completing the assembly of the flood control unit.

[0059] When the assembled flood control units are spliced, the first dovetail groove convex rail 19 is slidably connected to the first dovetail groove concave rail 18 on the adjacent frame 11, so that the flood control units can be assembled together. Assembling the corresponding number of flood control units according to the installed flood control length completes the assembly of the flood control device.

[0060] Finally, the sealing airbag 21 is inflated through the inflation nozzle 24, and then the embedded parts or bolts are installed in the first fixing hole 26, so that the frame 11 can be fixed to the ground. At the same time, after adjusting the angle of the support rod 27, the second fixing plate 28 is fixed to the ground, thus completing the installation of the flood control device, ensuring the stable structure of the flood control device after installation. At the same time, when the flood control device is impacted by water flow, the impact can be effectively buffered by the sealing airbag 21, ensuring the stability of the flood control device during use.
