Intelligent buoyancy type flood control and water retaining device for ventilation pavilion and control method

Abstract

The invention discloses an intelligent buoyancy type flood control and water retaining device for a ventilation pavilion and a control method. The device comprises a water retaining plate, a shell, a buoyancy assembly, an on-site monitoring system and an electrical control unit. The overall structure of the water baffle is matched with the shape of the ventilation pavilion, and the water baffle is formed by splicing a plurality of water baffles. The shell accommodates the buoyancy assembly and the water baffle, a water inlet hole is formed in the bottom, an extending opening is formed in the top, and a sealing tape is arranged between the extending opening and the baffle. The buoyancy assembly comprises a buoyancy device and a guide device. The buoyancy device drives the water baffle to float upwards. The guiding device is used for guiding the buoyancy device. The on-site monitoring system collects water level information and water baffle state information at the corresponding position of a position sensor in real time through a water level gauge and the position sensor, and transmits the information to the electrical control unit. Compared with preset parameters, judging and displaying are performed. The flood prevention capacity of the ventilation pavilion in rainstorm is improved, the station is prevented from being flooded, and subway operation safety is ensured. The automation degree of monitoring is improved, the speed is high, and the efficiency is high.

Description

technical field [0001] The invention belongs to the field of subway station ventilation, and in particular relates to a buoyancy type flood control and water retaining device for a wind pavilion of a subway station. Background technique [0002] During the rainy season and flood season, continuous torrential rains caused severe ground water accumulation, causing floods to pour into the subway from the air outlet surface of the wind pavilion hole, causing adverse consequences such as subway suspension and passenger stranded. [0003] The orifice surface of the existing wind pavilion has a certain height, which can play a certain effect of blocking water and preventing flooding. If the height of accumulated water exceeds the surface of the wind pavilion, it will be discharged into the subway through the wind pavilion. The internal drainage facilities cannot play the role of drainage and flood discharge in a short time, resulting in water accumulation inside the subway, threate...

Problems solved by technology

If the height of the accumulated water exceeds the surface of the Fengting mouth, it will be discharged into the subway through the Fengting mouth. The internal drainage facilities cannot play the role of drainage and flood discharge in a short time, resulting in water accumulation inside the subway, threatening the safety of the subway operation
