Technical Field

[0001] The utility model belongs to the technical field of power cables, and in particular relates to a fireproof and flame-retardant cable. Background Art

[0002] Fire-retardant power cables refer to cables used for transmitting and distributing electrical energy. They are commonly used in urban underground power grids, lead-out lines of power stations, internal power supplies of industrial and mining enterprises, and underwater transmission lines across rivers and seas. The proportion of cables in power lines is gradually increasing.

[0003] The fire-retardant cables currently available on the market have the following problems in actual use:

[0004] 1. When the traditional fire-retardant cable is actually used, it needs to be transported and installed in a suitable position before use. During installation, the fire-retardant cable is in contact with the ground as a whole. At this time, during the stretching process, it will rub against the ground, which will cause the surface of the fire-retardant cable to be worn, and the protection is poor during use;

[0005] 2. During the use of most fire-retardant cables, they need to be installed in trenches dug in advance. When the fire-retardant cables are placed in the trench, they do not have fixing devices, so the location of the fire-retardant cables may extend out of the trench, which is inconvenient to install.

[0028] In order to better understand the purpose, structure and function of the utility model, the fire-proof and flame-retardant cable of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1-5 As shown, a fire-retardant cable of the utility model comprises a low-smoke halogen-free outer sheath 1, a first fixing ring 6 is fixedly connected to the surface of the low-smoke halogen-free outer sheath 1, and a second fixing ring 7 is fixedly connected to the surface of the low-smoke halogen-free outer sheath 1. By installing the first fixing ring 6 and the second fixing ring 7, the first fixing ring 6 and the second fixing ring 7 can be used to provide a limiting effect for the anti-wear sleeve 9, so that the anti-wear sleeve 9 will not be displaced, and the stability is relatively strong during use. The anti-wear sleeve 9 is sleeved on the surface of the low-smoke halogen-free outer sheath 1, one end of the anti-wear sleeve 9 is attached to one end of the first fixing ring 6, and the other end of the anti-wear sleeve 9 is attached to one end of the second fixing ring 7. The anti-wear sleeves 9 are equidistantly distributed. By installing the anti-wear sleeves 9, when the fire-retardant cable is stretched on the ground, the anti-wear sleeve 9 will contact the ground. At this time, the anti-wear sleeve 9 can be used to prevent the fire-retardant cable from directly contacting the ground, thereby providing an anti-wear effect for it, and the protectiveness is relatively strong during use.

[0030] The surface of the low-smoke zero-halogen outer sheath 1 is sleeved on the bottom plate 12, the surface of the bottom plate 12 is welded with a fixing rod 13, the other end of the fixing rod 13 is welded with a strip plate 14, the bottom of the strip plate 14 is fixedly connected to an internal threaded seat 15, the internal threaded seat 15 is sleeved with an external threaded rod 17, the other end of the external threaded rod 17 is fixedly connected to a ground nail 16, and a nut 18 is welded on the surface of the external threaded rod 17. When the fire-retardant cable is placed inside the ground trench, the ground nail 16 can be used to embed it into the soil, and then the fire-retardant cable can be fixed, so that the fire-retardant cable is fixed in the ground trench, so that the fire-retardant cable is always in the ground trench during subsequent filling, which is very convenient to install.

[0031] A snap ring 8 is welded to the side of the second fixing ring 7, and a slot 11 is opened at the other end of the anti-wear sleeve 9. The snap ring 8 is embedded in the slot 11. By installing the snap ring 8 and opening the slot 11, and after the snap ring 8 is embedded in the slot 11, the anti-wear sleeve 9 can be further fixed, so that the anti-wear sleeve 9 has greater stability.

[0032] The surface of the bottom plate 12 is connected to the clamp ring 19 through a rotating shaft, and the other end of the clamp ring 19 is fixedly connected to the first clamp block 22. The second clamp block 23 is welded on the surface of the bottom plate 12, and the surface of the first clamp block 22 is attached to the second clamp block 23. Bolts are installed inside the first clamp block 22, and the bolts penetrate the second clamp block 23. The clamp ring 19 is installed and rotated by the rotating shaft until the surface of the first clamp block 22 is attached to the second clamp block 23. At this time, the first clamp block 22 can be fixed to the second clamp block 23 by bolts, and then the bottom plate 12 can be fixed to the surface of the low-smoke halogen-free outer jacket 1. At this time, the bottom plate 12 can be provided with installation and disassembly effects, which is very convenient to use.

[0033] A groove 20 is provided inside the clamp ring 19, and an anti-slip strip 21 is bonded inside the groove 20. The clamp ring 19 is symmetrically distributed, and the anti-slip strip 21 is symmetrically distributed. By installing the anti-slip strip 21, when the inner wall of the clamp ring 19 is attached to the surface of the low-smoke zero-halogen outer jacket 1, the stability of the contact position can be increased, so that it will not slide, and the stability is strong during use.

[0034] The surface of the anti-wear sleeve 9 is fixedly connected to the ball head 10, which is distributed in a ring shape. The fireproof belt 2 is sleeved inside the low-smoke and halogen-free outer jacket 1, the copper braided sleeve 3 is sleeved inside the fireproof belt 2, the flame retardant 4 is sleeved inside the copper braided sleeve 3, and the cable 5 is installed inside the flame retardant 4. By installing the ball head 10, the volume of the anti-wear sleeve 9 is expanded by utilizing the ball head 10, thereby further improving the anti-wear effect of the anti-wear sleeve 9, and the protective performance is stronger when used.

[0035] The working principle of the fire-retardant cable: When using the fire-retardant cable, the bottom plate 12 should be placed on the surface of the low-smoke zero-halogen outer sheath 1 first, and then the clamp ring 19 should be rotated by the shaft until the surface of the first clamp block 22 is attached to the second clamp block 23. At this time, the first clamp block 22 can be fixed to the second clamp block 23 by bolts, and then the bottom plate 12 can be fixed to the surface of the low-smoke zero-halogen outer sheath 1. At this time, the bottom plate 12 can be provided with installation and disassembly effects, which is very convenient to use. Then the external threaded rod 17 on the ground nail 16 is installed inside the internal threaded seat 15 on the strip plate 14. After that, The fire-retardant cable can be installed in a trench dug in advance. During the installation process, when the fire-retardant cable is stretched on the ground, the anti-wear sleeve 9 will contact the ground. At this time, the anti-wear sleeve 9 can prevent the fire-retardant cable from directly contacting the ground, thereby providing it with an anti-wear effect. It has strong protection when used. Afterwards, the fire-retardant cable is placed inside the trench, and the ground nails 16 are embedded in the soil to fix the fire-retardant cable. The fire-retardant cable is fixed in the trench, so that the fire-retardant cable is always in the trench during subsequent filling, which is very convenient to install.
