Cable transition interface of mining lifesaving cabin

Abstract

The invention belongs to the cable transition interface technology field, especially relating to a cable transition interface of a mining lifesaving cabin. A technical problem which needs to be solved is providing a good heat insulation performance good sealing cable transition interface of the mining lifesaving cabin. An employed technical scheme is as follows: the cable transition interface of the mining lifesaving cabin comprises a cable seat, a connection screw and an installation seat, the installation seat is installed on a wall of the lifesaving cabin, and the cable seat is fixedly connected with the installation seat through the connection screw; the cable seat comprises a cable cover and at least a communication connector, and the connector is welded on the cable cover and is in a hole which is adapted with an external diameter of the communication connector; the installation seat is made of heat insulation material; a sealing gasket is provided between the installation seat and the cable seat; the communication connector is provided with an explosion-proof cable sleeve inside; a cable through hole opened on the wall of the cabin is provided with a heat insulation sleeve, and the heat insulation sleeve is in interference fit with the wall of the cabin. According to the invention, a heat insulation performance of the lifesaving cabin is improved.

Description

technical field [0001] The invention discloses a cable transition interface for a mine rescue cabin, which belongs to the technical field of cable transition interfaces, and in particular relates to a cable transition interface for a mine rescue cabin. Background technique [0002] The mine rescue cabin is a refuge for the underground personnel to protect themselves in case of a sudden accident. If the underground power supply and communication facilities are not damaged when the mine disaster occurs, the underground power supply should be the first choice for the environmental monitoring of the rescue cabin. The system and lighting system are powered to maintain a longer escape time and create more favorable conditions for rescue. Therefore, it has very positive and far-reaching significance to be provided with a cable transition interface on the bulkhead of the mine rescue cabin. [0003] At present, the cable transition interface of the existing mining rescue cabin is ge...

AI Technical Summary

Problems solved by technology

[0003] At present, the cable transition interface of the existing mining rescue cabin is generally welded on the bulkhead and extends into the cabin body, causing the metal seat to directly contact with the interior, failing to effectively block the conduction of external heat into the cabin, which is harmful to the rescue cabin. In other words, the cable transition interface becomes a serious heating source, which seriously affects the thermal insulation performance of the mining rescue cabin
