For the present invention by setting fire-retardant shearing device outside cable main, the intensity of a fire when condition of a fire occurring with effective control is climing
Prolong, reduce potential safety hazard as far as possible, reduce loss.During work, when the condition of a fire occurs, during fire spreading to fire-retardant shearing device,
Temperature reaches fuse member by housing, so that fuse member fuses, cutting knife is cut in cable main or straight in the presence of elastic component
Cut-out cable main is connect, effectively to split the cable of its both sides, prevents the intensity of a fire from continuing to spread.Wherein, the blade of cutting knife is away from cable
Main body certain distance so that when fuse member fuses, with enough kinetic energy during the tangential cable main of cutting knife.In addition, the institute of both sides
On the one hand positional stability that positioner can effectively ensure that fire-retardant shearing device is stated, on the other hand provides one effectively
The device of fixed cable, while the matching relationship of ring-shaped slide groove and sliding ring, in fixed cable, to avoid to cable
Reverse.The positioner of both sides also acts the fire retardation to the partial cables, with avoid fire-retardant shearing device directly by compared with
The big intensity of a fire is destroyed, and causes the failure of its fire-retardant cutting function.
As the present invention preferably, the cutting knife includes the blade of multi-disc gap setting, and the every blade is provided with least one
The individual elastic component and fuse member.The process that the structure to cut or cut off is more efficient, is cut off from multiple angles,
Gap relationships cause blade to be independent of each other in incision.
Fusing hole preferably, in the middle part of the blade is provided with as of the invention, the fuse member passes through the fusing hole, and described
The both ends of fuse member connect the case inside wall.The structure more can guarantee that the timely of cut-out, because fuse member is in fusing
The part in hole can be constantly subjected to a power, Gu when the temperature increases, the part will fuse at first.
As the present invention preferably, the blade of the blade is the arc for coordinating the cable main external surface shape.It is described
Structure causes the stress of the various pieces of blade in cut process to be more uniformly distributed, to ensure the fluency of cut process.
As the present invention preferably, the housing includes pressing close to the heat-insulating and sealing seat of the cable main, located at the sealing
Thermal conductive shell on seat.The heat-insulating and sealing seat is made of not transcalent material, with avoid the intensity of a fire or high temperature by every
Heat seal seat is transmitted in cable main, and thermal conductive shell then ensure that fuse member can fuse in time, to ensure its resistance
Fuel efficiency fruit.
As it is of the invention preferably, the seal receptacle its towards one end of the cable main be provided with seal groove, the sealing
Sealing strip is provided with groove.The structure ensure that the sealing of enclosure interior, to ensure the service life of fire-retardant shearing device.
As the present invention preferably, the fixture includes supporting plate, the fixed plate located at the supporting plate end, described solid
Fixed board is provided with multiple fixing holes.The structure of the fixture is simple, and fixed operation is convenient, and dress will be entirely positioned by fixing hole
Put and be fixedly connected with wall etc..
It is an advantage of the invention that：It is simple in construction, it is easy to use, cable system can be effectively protected, while fire can be controlled
The sprawling of gesture, to reduce loss.
