Abstract

The invention relates to a rigid contact screen sealing device which is positioned at a position at which a rigid contact screen passes a door leaf. The rigid contact screen sealing device comprises a profiled elastic block and a push mechanism. The profiled elastic block consists of an inner profiled elastic body wrapping the outer periphery of the rigid contact screen, a left outer profiled elastic body and a right outer profiled elastic body, and a loop-shaped elastic body, wherein the left outer profiled elastic body and the right outer profiled elastic body are pushed by guide heads of the push mechanism, can be gathered and sealed with the inner profiled elastic body and are opposite at the concave parts,. The left outer profiled elastic body and the right outer profiled elastic body are symmetrically connected to the front part of the left guide head and the right guide head and correspond to a left sealing box and a right sealing box which are arranged at two door leaves at the left side and the right side of the inner profiled elastic body. The front parts of the left sealing box and the right sealing box are provided with corresponding wedge shapes. The rear parts of the left sealing box and the right sealing box can accommodate the front parts of the guide heads. Limit stoppers are fixed at middle parts of the left sealing box and the right sealing box. The rigid contact screen sealing device realizes close and reliable sealing, simple structure, easy production and low cost and effectively solves the sealing problem of the rigid contact screen.

Description

technical field [0001] The invention relates to protective equipment for subway engineering, civil air defense engineering and national defense engineering, in particular to a rigid catenary sealing device for a protective airtight partition door of a rigid catenary power receiving subway section. Background technique [0002] With the development of urban transportation, many large and medium-sized cities in China have set off a new wave of subway transportation construction. According to the relevant provisions of my country's "Civil Air Defense Law", the construction of subway projects must also take into account the needs of civil air defense during wartime. At present, subways under construction are all The construction of civil air defense projects is divided into rigid catenary power receiving and catenary rail power receiving according to the different power receiving methods of the subway. The design and construction of the protective airtight partition door of the ca...
