The invention belongs to the technical field of city underground comprehensive pipe galleries, and particularly relates to a safety device for preventing road rainwater from entering an underground comprehensive pipe gallery. The safety device comprises a base, a cover plate and a hydraulic cylinder; and one side of the cover plate is hinged to the base, the hydraulic cylinder comprises a piston rod and a hydraulic cylinder barrel, one end of the piston rod is connected to the hydraulic cylinder barrel in a sliding manner, and the other end of the piston rod is hinged to the lower surface of the cover plate. The safety device is installed at the bottom of a ventilating shaft, parts like civil engineering structures do not need to be additionally arranged, installation is convenient, and cost is saved. When waterlogging happens in a city, as the road rainwater accumulation depth is increased, when the accumulated water height is larger than the height of the bottom of a window-shade installed in a comprehensive pipe gallery ventilating shaft and rainwater overflows and enters the comprehensive pipe gallery, the safety device will be automatically closed, the aim of preventing the comprehensive pipe gallery from water logging is achieved, and safety of the comprehensive pipe gallery is guaranteed. After the road water accumulation height is reduced, accumulated water at the upper portion of the safety device is removed through a drainage facility, then the safety device is opened, and normal work of a ventilation opening is recovered.
Description
technical field [0001] The invention belongs to the technical field of urban underground comprehensive pipe gallery, and specifically relates to a safety device for preventing road rainwater from entering into an underground comprehensive pipe gallery; the invention also relates to an application system of a safety device for preventing road rainwater from entering into an underground comprehensive pipe gallery. Background technique [0002] The comprehensive pipe gallery is a structure and ancillary facilities built underground to accommodate two or more types of urban engineering pipelines. In order to ensure the air quality and personnel safety inside the comprehensive pipe gallery, the comprehensive pipe gallery needs to have ventilation shafts (air inlets and vents) for ventilation. The ventilation openings of the existing natural gas tanks and electric cable cabins in the integrated pipe gallery are set as follows: no more than 200m as a ventilation partition (the rest...
