Semi-automatic anti-flooding device for rail transit entrance/exit

Abstract

The invention relates to the technical field of rail transit, in particular to a semi-automatic anti-flooding device for a rail transit entrance / exit. An anti-flooding embedded groove is formed in anentrance / exit ground wall, an anti-flooding baffle movably covers the anti-flooding embedded groove, and one side wall of the anti-flooding embedded groove is connected with one side edge of the anti-flooding baffle through a hinge joint piece. A water stop connecting belt is connected between the side, provided with the hinge joint piece, of the anti-flooding baffle and the inner wall of the anti-flooding embedded groove. The bottom wall of the anti-flooding baffle is connected with one end of a pneumatic supporting rod in a screwed mode, and the other end of the pneumatic supporting rod is screwed into the inner wall of one side of the flood-proof embedded groove and is opposite to the water stop connecting belt. Once a large flood occurs, a worker can perform on-site, concise and quickinstallation without special equipment. The device has the remarkable advantages of being simple in structure, high in leakproofness and reliability, free of occupying precious underground space resources of a subway, easy to operate, maintain and manage, rapid in recovery after flood and the like.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a semi-automatic anti-flooding device for rail transit entrances and exits. Background technique [0002] At present, the anti-flooding facilities at the entrances and exits of rail transit are relatively single. Many existing subway entrances and exits only use the method of stacking sandbags. In recent years, anti-flooding gates have been reserved in the design of entrances and exits, but anti-flooding baffles need to be assembled on site. The above several methods all have the following problems: 1. It takes a long time to close, and it takes a lot of personnel; Flood baffles require a large amount of space for storage, which is irreconcilable. The storage points of some stations are far away from the entrance and exit, which increases the installation time and easily delays the timing of flood prevention. 4.

Problems solved by technology

[0002] At present, the anti-flooding facilities at the entrances and exits of rail transit are relatively single. Many existing subway entrances and exits only use the method of stacking sandbags. In recent years, anti-flooding gates have been reserved in the design of entrances and exits, but anti-flooding baffles need to be assembled on site

The above several methods all have the following problems: 1. It takes a long time to close, and it takes a lot of personnel; Flood baffles require a large amount of space for storage, which is irreconcilable. Some station storage points are far away from the entrance and exit, which increases installation time and easily delays the timing of flood prevention. 4. After the flood, the restoration work is cumbersome, and some facilities cannot be reused

However, the anti-flooding baffle in the above-mentioned technical scheme needs to use hydraulic opening and closing equipment to raise the water baffle

On the one hand, the entrance and exit site is complicated, and the upper and lower guide grooves are easily blocked by obstacles, resulting in the inability to raise the flood prevention baffle; on the other hand, the hydraulic and pneumatic equipment system is complicated, and daily maintenance is difficult. Once a problem occurs during use, non-professionals cannot Operation, it is easy to miss the best time for flood prevention
