The equipment comprises equipment door leaves, an equipment door frame, equipment close locks, equipment hinges and a hydraulic driving device; the hydraulic driving device is connected with the equipment close locks and the equipment door leaves, and is composed of a control system and an executing mechanism; the equipment door leaves comprise a gate door leaf and a small door leaf; the equipment close locks comprise a gate close lock and a small door close lock; the equipment hinges comprise a gate hinge and a small door hinge; each equipment door leaf is composed of at least two modules which comprise a first module and a second module, the gate door leaf is formed by splicing a plurality of sets of first modules and second modules, the small door leaf is composed of a set of second modules. The equipment has a wide popularization and application prospect, and has significant combat readiness benefits and remarkable economic benefits.

Description

technical field [0001] The invention relates to a civil air defense protection equipment, in particular to a composite material civil air defense protection equipment for a hoisting port of an urban underground comprehensive pipe gallery, belonging to the field of civil air defense engineering protection equipment. 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 civil air defense construction of pipe corridors in my country is in its infancy. At present, there is no serialized orifice protection equipment specially applied to comprehensive pipe corridors, which cannot meet the fortification requirements of comprehensive pipe corridors. The hoisting port is the hole opened on the comprehensive pipe gallery to hoist various pipelines and equipment into or out of the comprehensive pipe gallery. Th...

Problems solved by technology

However, due to the high density of reinforced concrete and steel and poor corrosion resistance, there are disadvantages such as heavy weight, easy corrosion, laborious operation, and high cost; in terms of structural design: the door leaf structure of the current protective equipment mostly adopts beam-plate, arch, etc. Plate type and arched plate type, etc.; locking and hinge design: at present, the locking mechanism mostly adopts sliding bolt type and latch type, and hinge mechanism can be divided into through shaft type and split type, etc.; automatic control scheme design: for Protection equipment with automation needs needs to design its automation control system. At present, relatively mature products include: one machine with two functions, one machine with three functions, electric control protection equipment, vertical rotation type, lifting type hydraulic control protection equipment, etc.

However, due to the disadvantages of complex transmission mechanism and single control method, the above control method has low control accuracy and poor reliability.
