Description
Technical field
The present invention relates to cable cavern high temperature resistant waterproof stopper.
Background technology
In many transformer stations, have many lines all to adopt power cable, when passing through floor or partition wall must through private cable hole, for the ease of install, general cable cavern is bigger than power cable diameter, just there is gap after cable installation, stopper should be installed in the gap between power cable and hole according to regulatory requirements, but existing closure installation and removal are complicated, non-refractory, fire protecting performance is bad, and the excessive water resistance in gap between stopper and cable cavern is bad.
Summary of the invention
For above-mentioned technical problem, it is an object of the invention to: provide a kind of and mount and dismount cable cavern high temperature resistant waterproof stopper simple, high temperature resistant, that fire protecting performance is good and water resistance is good.
nullIn order to solve above-mentioned technical problem，The present invention is by the following technical solutions: cable cavern high temperature resistant waterproof stopper，Stopper is formed by organizing plugging part more，Described stopper has cable installing hole，Described plugging part includes pre-ceramic block、Can the middle sealing gasket of deformation、Rear ceramic block and connection fixture，Described pre-ceramic block has pre-ceramic block installing hole，Described middle sealing gasket has middle sealing gasket installing hole，Described rear ceramic block has rear ceramic block installing hole，Described pre-ceramic block installing hole、Middle sealing gasket installing hole and rear ceramic block installing hole communicate，Described connection fixture traverse pre-ceramic block installing hole、Middle sealing gasket installing hole and rear ceramic block installing hole，Make pre-ceramic block、Middle sealing gasket and rear ceramic block fit together，Described pre-ceramic block is provided with in pre-ceramic block fire prevention gear and gear of preventing fires outside pre-ceramic block，Described rear ceramic block is provided with in rear ceramic block fire prevention gear and gear of preventing fires outside rear ceramic block，Make stopper is formed front interior fire prevention back-up ring、Front outer back-up ring of preventing fires、Fire prevention back-up ring and rear outer fire prevention back-up ring in rear，It is front fire prevention groove between fire prevention back-up ring and front outer fire prevention back-up ring in before described，It is rear fire prevention groove between fire prevention back-up ring and rear outer fire prevention back-up ring in after described.
nullCable cavern high temperature resistant waterproof stopper provided by the invention provides the benefit that: owing to stopper is formed by organizing plugging part more，Described stopper has cable installing hole，Described plugging part includes pre-ceramic block、Can the middle sealing gasket of deformation、Rear ceramic block and connection fixture，Described pre-ceramic block has pre-ceramic block installing hole，Described middle sealing gasket has middle sealing gasket installing hole，Described rear ceramic block has rear ceramic block installing hole，Described pre-ceramic block installing hole、Middle sealing gasket installing hole and rear ceramic block installing hole communicate，Described connection fixture traverse pre-ceramic block installing hole、Middle sealing gasket installing hole and rear ceramic block installing hole，Make pre-ceramic block、Middle sealing gasket and rear ceramic block fit together，Described pre-ceramic block is provided with in pre-ceramic block fire prevention gear and gear of preventing fires outside pre-ceramic block，Described rear ceramic block is provided with in rear ceramic block fire prevention gear and gear of preventing fires outside rear ceramic block，Make stopper is formed front interior fire prevention back-up ring、Front outer back-up ring of preventing fires、Fire prevention back-up ring and rear outer fire prevention back-up ring in rear，It is front fire prevention groove between fire prevention back-up ring and front outer fire prevention back-up ring in before described，It is rear fire prevention groove between fire prevention back-up ring and rear outer fire prevention back-up ring in after described，Only need to be assembled by organizing the gap that plugging part puts between cable and hole when therefore installing more，Make installation and removal simple and convenient，The pre-ceramic block being made of ceramic materials can bear higher temperature with rear ceramic block compared with metal，During breaking out of fire, flame is at front interior fire prevention back-up ring、Front outer back-up ring of preventing fires、Under the stop of rear interior fire prevention back-up ring and rear outer fire prevention back-up ring, flame can be kept off back and being sprayed toward opposite direction，That is under the stop of front fire prevention groove and rear fire prevention groove, flame can be kept off back and being sprayed toward opposite direction，Flame is avoided to enter from the gap between the gap between stopper and hole and stopper and cable，The cable and the middle sealing gasket that prevent stopper rear are burned out，Fire protecting performance is greatly improved，When stopper installs，The middle sealing gasket of deformation can uphold toward both sides under the extruding of pre-ceramic block and rear ceramic block and become big，The outward flange of middle sealing gasket is made to abut sealing with the inwall of hole，The inward flange of middle sealing gasket abuts sealing with the outer surface of cable，Water cannot be flowed in the middle of gap，Thus water resistance is greatly improved.
