Detailed Description
As shown in figure 1, the flame-retardant and pressure-resistant cable comprises more than one fixing part 4, an elastic fire extinguishing assembly is fixedly arranged between every two adjacent fixing parts 4, more than one outer protection sheet 7 is arranged outside the elastic fire extinguishing assembly, the more than one outer protection sheets 7 are arranged around the fixing parts 4 in a circle at equal intervals and are spliced with each other to form a circular outer tegument, two sliding grooves 13 are respectively arranged on the end surfaces of two sides of the fixing parts 4, a sliding block 5 is arranged on the end surface of the outer protection sheet 7 opposite to the sliding grooves 13, the outer protection sheets 7 are respectively buckled in the sliding grooves 13 in a sliding way through the sliding blocks 5 on the two sides, a group of springs 8 are arranged in the sliding grooves 13, a through groove 12 is respectively arranged on the fixing part between the two sliding grooves 13, a cable core wire 6 is arranged at the top of each outer protection sheet 7, the cable core wire 6 passes through the through grooves 12 in the middle of the, the springs 8 are stretched after the outer protective sheet 7 is spread.
Wherein, elasticity subassembly of putting out a fire all adopts an elasticity gasbag 2, and its inside has a gas storage chamber 1, and the gas storage chamber 1 intussuseption is full of inert gas, and 6 parts of cable conductor are detained in the fixed intracavity of the arc of 7 bottoms of external protection pieces, and cable conductor 6 slides in the middle of the fixed part along leading to groove 12, and the slip condition takes place after the elasticity gasbag is destroyed. The cable core 6 is partially buckled in the elastic air bag 2 and forms an arc-shaped inner convex part 3. The cable is normal use state this moment, and all cable conductor independent settings can not have thermal transmission, and heat dispersion can promote greatly. When the cable core wires are pressed, the internal elastic air bags are pressed, so that the elastic air bags are pressed to deform, elastic buffering is realized, and all the cable core wires are in a flexible contact state without rigid pressing in the state;
when the extrusion shearing force is too large and exceeds the bearing pressure of the elastic air bag, the elastic air bag can explode, the explosion sound can be transmitted out, and an operator can stop working in advance by the sound to prevent further shearing. And after the elastic air bag explodes, all the outer protective sheets return under the tension of the spring, as shown in fig. 3, and at the moment, a secondary protective structure is formed to further protect the core wire, and the outer protective sheets are utilized to continuously bear the pressure.
As shown in fig. 2, the bottom of one end of the spring 8 is fixedly bonded to the bottom of the sliding groove 13, the other end of the spring is fixedly bonded to the bottom of the buckled sliding block, the spring 8 is stretched by the elastic airbag 2, and an elastic pulling force is generated at the moment, so that the spring can return after the elastic airbag is damaged, and further the outer protection plates are stretched towards the bottom, so that each outer protection plate returns to form a circular inner protection structure.
Wherein, the position that the lower terminal surface of external protection piece 7 just faced elasticity fire extinguishing assembly all sets up two arc contact site 9, and the lower terminal surface of arc contact site 9 all forms a bottom open-ended heart yearn between two adjacent arc contact site 9 and places the chamber with the outer wall contact of elasticity gasbag 2 of elasticity fire extinguishing assembly, and the bottom open end that the chamber was placed to the heart yearn is sealed through gas filled elasticity gasbag 2. Because cable conductor 6 independently sets up and places the intracavity in the heart yearn, and the bottom is contacted as elastic buffer by elasticity gasbag 2 again, so such structure makes the cable when using under normal condition, have fine independent heat dispersion and have fine elasticity buffer capacity, the heat can not consequently the circumstances such as spontaneous combustion can not appear in the transmission between the cable conductor, in case one of them cable conductor spontaneous combustion, then can burn the elasticity gasbag 2 of bottom, elasticity gasbag 2 gas leakage like this, a large amount of inert gases are poured into the heart yearn and are placed the intracavity, replace oxygen, block the spontaneous combustion with this, unusual safety.
wherein, the elastic airbag 2 all is the cylindricality, and the both sides face intermediate position of elastic airbag 2 all forms a bonding face, and this bonding face avoids spout 13 and logical groove 12, and the bonding face is scribbled glue through both sides and is fixed with the terminal surface bonding of fixed part 4 respectively. More than one outer protection sheet 7 is encircled into a circular structure, an inner protection cavity 21 is formed in each outer protection sheet, when the elastic air bag 2 is damaged due to pressure or external flame, all the outer protection sheets 7 can be close to the center, as shown in fig. 3, an inner protection cavity is formed in each outer protection sheet for secondary protection of each cable core wire, and the use safety of the cable is greatly improved. The number of the outer protection plates in the embodiment depends on the number of the cable cores, and the size and the number of the outer protection plates can be adjusted according to actual needs.
The invention has the beneficial effects that: according to the invention, the core wires of each cable are respectively and independently arranged, so that heat among the core wires can not be mutually transferred, and the heat is independently radiated in the independent cavities, and the heat radiation performance is good;
The expanded elastic air bag is arranged in the middle of each cable core wire, so that the elastic air bag is utilized to resist shearing and extrusion, and the purpose of buffering is achieved; when the shearing force or the extrusion force is large, the elastic air bag can be broken, so that a sound is emitted to inform an operator to stop construction, and meanwhile, all the outer protection sheets return under the action of the springs to form a closed inner protection money which is insufficient to carry out secondary protection on each cable core wire;
When a fire disaster occurs, the elastic air bag can be damaged by flame, so that the elastic air bag explodes under the action of the elastic force of the spring and the elastic air bag, and then the explosion force and the inert gas inside the elastic air bag are utilized to quickly extinguish the fire, and the purpose of extinguishing the fire is achieved.
the above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention.
