Steel-structure civil air defense protection equipment for manhole of urban underground comprehensive pipe galley

Abstract

The invention belongs to the technical field of protection equipment in civil air defense engineering, and in particular relates to steel-structure civil air defense protection equipment for a manholeof an urban underground comprehensive pipe galley. The steel-structure civil air defense protection equipment comprises a doorframe, hinges, a door leaf, a latch and an electric driving device, wherein the doorframe is arranged on a basal body of the manhole and is used for installing the door leaf and transferring load; the door leaf is a steel-structure door leaf and is hinged with the doorframe through the hinges; the latch is arranged on the door leaf and is used for being matched with the doorframe to lock or unlock the door leaf; and the electric driving device is connected with the door leaf and the latch and is used for realizing the turning of the door leaf and the opening and closing of the latch. The steel-structure civil air defense protection equipment can provide efficient and reliable hole protection measures for the manhole, guarantees the safety of the internal personnel and equipment of the engineering, and has important guiding significance and application value forpreserving the strength of a wartime city and improving the survivability of an important city transportation pipeline.

Description

technical field [0001] The invention belongs to the technical field of civil air defense engineering protective equipment, and in particular, the invention relates to a steel structure civil air defense protective equipment for an inspection port of an urban underground comprehensive utility gallery. Background technique [0002] The urban comprehensive pipeline corridor is the underground urban pipeline comprehensive corridor, which is an important infrastructure and "lifeline" project to ensure the operation of the city. The inspection port, also known as the escape port, is a hole opened on the comprehensive pipe gallery for maintenance personnel to enter and exit the project and for emergency escape. Protective equipment can usually be divided into protective doors, protective airtight doors, blocking plates, valve damping systems, etc. according to their functions; according to their materials, they can usually be divided into reinforced concrete protective equipment, s...
