Abstract
The utility model discloses a sealing structure of a busbar for a protective air-tight portioning door of a subway interval. The sealing structure comprises a clamp for fixedly clamping electric wires of a rail, wherein a sealing ring is sleeved outside the clamp, is integrally formed according to the shape of the clamp and is only provided with an opening. According to the sealing structure of the busbar for the protective air-tight portioning door of the subway tunnel, as the integrally formed rubber sealing ring is adopted outside the clamp and is fastened outside the clamp according to the shape of the clamp, the integral tightness of the busbar is guaranteed.
Description
Technical field
The utility model refers in particular to a kind of Subway Tunnel protective airtight partition door bus-bar hermetically-sealed construction about a kind of bus-bar.
Background technology
Bus-bar is the electric supply installation of subway circulation, after guaranteeing that people's air defense is enabled, and the operation in short-term of subway, bus-bar can not be extractd.Therefore to carry out shutoff to bus-bar after protective airtight partition door being enabled.Common bus structures as shown in Figure 3, wherein, electric wire 90 is clamping by fixture 91, is wrapped on this fixture 91 by a plurality of caulking gums 92 are spliced to form an integral body in the outside of fixture 91.Because caulking gum 92 is to be spliced to form holisticly, the sealing of bus-bar can not be guaranteed and has potential safety hazard.
The utility model content
Because the problems referred to above, the utility model provides a kind of Subway Tunnel protective airtight partition door bus-bar hermetically-sealed construction, comprise the fixture for the clamping rail electric wire, described fixture outer cover is provided with a sealing ring, and described sealing ring is integrally formed according to the shape of described fixture and only have an opening.
Further, described sealing ring is fastening, and to be arranged at described fixture outside, and the inner surface of described sealing ring and the external surface of described fixture are close to mutually.
Further, described sealing ring adopts rubber seal, also is provided with sealing joint strip between described sealing ring and described fixture.
The fixture of Subway Tunnel protective airtight partition door bus-bar hermetically-sealed construction of the present utility model is outside adopts integrally formed rubber seal, and sealing ring be arranged on its outside fastening according to the shape of fixture guaranteed the overall tightness of bus-bar.
