DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model.

[0023] like Figures 1 to 5As shown, a subway station flood prevention device includes two groups of mounting frames 101 arranged at the entrance of the subway station, multiple groups of flood baffles 102 for flood prevention and isolation are connected between the two groups of mounting frames 101, and also includes a mounting assembly arranged between the flood baffles 102 and the two groups of mounting frames 101 for assisting the stacking of the flood baffles 102, an automatic lifting flood prevention assembly for automatically lifting and lowering according to the water level for flood prevention is arranged between the two groups of mounting frames 101, and an extrusion limit assembly connected with an extrusion limit for stacking multiple groups of flood baffles 102 is arranged on the mounting frame 101;

[0024] The automatic lifting flood prevention assembly includes a lifting plate 201 arranged between two groups of mounting frames 101, and the two sides of the lifting plate 201 are respectively set against one side of the two groups of mounting frames 101, and the lifting plate 201 is located in front of each stacked flood prevention baffle 102, and the flood prevention baffle 102 is connected to multiple groups of stacked flood prevention baffles 102 through a connecting assembly, and a floating plate 202 is arranged in front of the lifting plate 201;

[0025] During the flood prevention operation at the subway station, the flood prevention device uses the lifting plate 201 and multiple flood baffles 102 to block the flood in front of the subway station entrance. In the process of blocking and preventing floods, the buoyancy between the floating plates 202 in front of the lifting plate 201 and the flood is used to make the lifting plate 201 rise synchronously with the rise of the flood level. The rise of the lifting plate 201 ensures the height of the flood barrier, thereby further ensuring the flood prevention effect of the subway station.

[0026] There are multiple groups of floating plates 202, and the multiple groups of floating plates 202 are equidistantly arranged on one side of the lifting plate 201; the multiple groups of floating plates 202 equidistantly arranged facilitate the lifting plate 201 to move upward more sensitively and stably.

[0027] The connecting assembly includes a plurality of T-shaped connecting grooves 301 opened on the front side of the flood baffle 102, and a T-shaped back plate 302 matched with the T-shaped connecting grooves 301 is fixed on one side of the lifting plate 201; after multiple groups of flood baffles 102 are stacked and squeezed to limit their positions, the connection between the T-shaped connecting grooves 301 and the T-shaped back plate 302 facilitates the installation and connection of the lifting plate 201 on the front side of each flood baffle 102.

[0028] The installation component includes a T-shaped slide groove 401 opened on the installation frame 101, and T-shaped blocks 402 that are matched with the T-shaped slide groove 401 are fixed on both sides of the flood baffle 102; through the installation and connection function of the T-shaped slide groove 401 and the T-shaped block 402, it is convenient to stack multiple groups of flood baffles 102 from bottom to bottom in sequence between two groups of installation frames 101.

[0029] The extrusion limit assembly includes a mounting plate 501, on which a threaded sleeve 502 is fixed, on which a threaded extrusion rod 503 is threadedly engaged and connected, and a driving pin 504 is fixed to the upper end of the threaded extrusion rod 503; the mounting plate 501 is inserted into the card slot 6, and the threaded extrusion rod 503 is driven to rotate by the driving pin 504. During the rotation of the threaded extrusion rod 503, the threaded extrusion rod 503 and the threaded sleeve 502 are mutually engaged and driven, so that the threaded extrusion rod 503 moves downward and the lower end of the threaded extrusion rod 503 is abutted against the upper end of the topmost flood baffle 102 after stacking, so that the stacked multiple groups of flood baffles 102 are squeezed, the gap between the stacked flood baffles 102 is reduced, and the flood prevention effect is ensured.

[0030] The mounting frame 101 is provided with a slot 6 for mounting the mounting plate 501 . The slot 6 facilitates quick installation and removal of the mounting plate 501 on the mounting frame 101 .

[0031] During the flood prevention operation of the flood prevention device at the subway station, multiple groups of flood prevention baffles 102 are stacked from bottom to bottom between the two groups of mounting frames 101 through the installation connection of the T-shaped slide groove 401 and the T-shaped block 402. After the stacking is completed, the mounting plate 501 is clamped into the clamping groove 6, and the threaded extrusion rod 503 is driven to rotate by the driving pin 504. During the rotation of the threaded extrusion rod 503, the threaded extrusion rod 503 is driven to move downward through the mutual meshing transmission between the threaded extrusion rod 503 and the threaded sleeve 502, so that the lower end of the threaded extrusion rod 503 is against the upper end of the top flood prevention baffle 102 after stacking, and the stacked multiple groups of flood prevention baffles 102 are squeezed, and the gap between each flood prevention baffle 102 after stacking is reduced, so as to ensure the flood prevention effect;

[0032] After multiple groups of flood baffles 102 are stacked and squeezed to limit their positions, the lifting plate 201 is installed and connected to the front side of each flood baffle 102 through the connection between the T-shaped connecting groove 301 and the T-shaped back plate 302. The lifting plate 201 and the multiple flood baffles 102 are used to block and prevent floods in front of the subway station entrance.

[0033] In the process of flood barrier, the buoyancy between the floating plates 202 in front of the lifting plate 201 and the flood causes the lifting plate 201 to rise synchronously with the rising flood level. The rise of the lifting plate 201 ensures the height of the flood barrier, further ensuring the flood prevention effect of the subway station.
