Intelligent lifting type flood control water retaining device for fan pavilion and control method

Abstract

The invention provides an intelligent lifting type flood control water retaining device for a fan pavilion and a control method. The device comprises a baffle assembly, a shell, a lifting assembly, a field monitoring system and an electrical control unit, wherein the baffle assembly is matched with the fan pavilion in shape; a sealing rubber strip is arranged on the periphery of the bottom of a baffle; the shell contains the lifting assembly and the baffle assembly and covers a foundation of a fan pavilion opening; a lifting opening is formed in the top of the shell; the sealing rubber strip seals the lifting opening when the baffle ascends; the lifting assembly comprises a linkage lifting mechanism and a motor; the field monitoring system comprises a water level gauge and a position sensor and collects information; and the electrical control unit receives the information and drives the linkage lifting mechanism to ascend and descend by controlling the motor to rotate forwards and backwards, and the baffle is made to stretch out and retract. The lifting mechanism is automatically controlled to drive the baffle to ascend and descend, the flood control capacity of the fan pavilion during rainstorm is improved, a station is prevented from being flooded, and the operation safety of a subway is ensured; and the automation degree is improved, the speed is high, and efficiency is high.

Description

technical field [0001] The invention belongs to the field of subway station ventilation, and in particular relates to an intelligent lifting type flood control and water retaining device for a wind pavilion of a subway station. Background technique [0002] In recent years, many cities such as Beijing, Guangzhou, Nanjing, Wuhan, and Shanghai have experienced severe waterlogging due to heavy rains, resulting in severe water accumulation in some areas. Some roads have been basically interrupted, and subway stations and underground garages have also been flooded. Some subway lines The outage also fully exposed that the process of urban modernization has seriously lagged behind in the planning, design and construction management of the urban drainage system. When the water level reaches the entrance of the subway and the shutters of the wind pavilion are designed, the subway station below the horizon will become a place for flood discharge. In some cases, the station will be flo...

AI Technical Summary

Problems solved by technology

[0003] The design height of the existing short wind pavilions in China (open wind pavilions without cover) is about 1m, which is not enough to resist rainwater backflow when heavy rain strikes. The domestic research on subway wind pavilion flood control devices is still in a blank stage. The development of anti-flooding equipment for wind pavilions is imminent
