Description
Technical field
The present invention relates to a kind of cable fire-proof sleeve pipe, category power cable laying safeguard field.
Background technology
At present in the laying of the multiple cable such as power cable, communication cable, generally require a plurality of cable and be focused directly at
Carry out intensive laying together, or need such as to arrange embedding for electric power cable etc. with building such as inside etc., especially in rings such as switchgear houses
In border, often a plurality of electric power cable needs closely to be arranged in the enough small spaces of cable, or in electric power cable outer cladding one
The sleeve pipe of layer PVC material, and the sleeve pipe lacks to high temperature resistivity and putting out and alert capability to fire, therefore works as generation
During fire or certain root cable is after fault is on fire anyway, as electric power cable arrangement is intensive or is embedded in the interior of articles such as building, no
The method very first time finds disaster hidden-trouble, more point of origin cannot be processed in the very first time, therefore, easily cause electric power cable
Large area is on fire to burn, and easily causes electric shock accidents, while also easily feed through to the power cable for closing on normal operation, from but
Accident infringement expands, and causes the great wasting of resources, and needs to put into more manpower and materials and take in recovering after calamity
Dean, therefore present electric power cable arrangement equipment cannot effectively be prevented to cable fire and be protected, to safety utilization of electric power,
Power circuit construction and operation safety cause serious security threat.
Content of the invention
The object of the invention is that and overcomes above-mentioned deficiency, provides a kind of cable fire-proof sleeve pipe.
For achieving the above object, the present invention is to be achieved through the following technical solutions：
A kind of cable fire-proof sleeve pipe, is made up of wire bushing, adapter sleeve, seal plug and broken line warning system, described shield
Line set is made up of at least two section wire-passing tubes, and is connected by adapter sleeve between wire-passing tube, and described adapter sleeve is by tube wall and baffle plate
Composition, wherein tube wall and baffle plate are for integral type structure and axial cross section is " H " type, wherein separately set cable-through hole on baffle plate, described
Wire-passing tube is hollow tubular structures, and described tube wall is made up of the outer wall that insulate, hot melt inwall, wherein insulation outer wall and hot melt inwall
Between spacing be not less than 1 centimetre, and by link of boards and constitute fire prevention chamber, described fire prevention chamber is along parallel point of wire-passing tube axis direction
Cloth, fills extinguishing chemical in described fire prevention chamber, by seal plug between insulation outer wall and hot melt inwall at described wire-passing tube two ends
Sealing, separately sets elastic protecting sleeve outside described wire-passing tube, described broken line warning system is by power supply, switch, buzzer, early warning electricity
Line and adjustment resistance are constituted, and described early warning electric wire is in parallel with buzzer with after adjustment resistant series, then by switch and electricity
Source connects, and wherein described early warning electric wire is separately embedded in hot melt inwall and in around distribution, described power supply, switch, buzzer
And adjustment resistance is placed in setting on the outside of elastic protecting sleeve.
Adapter sleeve material is rubber or hard PVC section bar.
Plug is hard PVC section bar.
Extinguishing chemical is dry ice, fire foam, powder extinguishing agent or sand.
Buzzer is acousto-optic integrated buzzer.
One aspect of the present invention can ignition of cable accident effectively and timely put out and reported to the police, so as to greatly reduce cable
Initiation fire risk, improves Electrical Safety performance, while also effectively having prevented a cable fault concrete on fire occurs to which
The harm of cable is closed on, the operation safety of transmission line of electricity is substantially increased, and damage by fire is greatly reduced, save big
After the calamity of amount, Resuming agent and the time that replys after shortening calamity, improve fire incident and exclude efficiency.
