According to the utility model, on one hand, the fluorescent protection layer made of the PC anti-ultraviolet film is installed on the outer side of the fluorescent layer, so that the cable can effectively reduce the damage of ultraviolet rays to the fluorescent layer under the action of the fluorescent protection layer when in use, and ensures that the fluorescent layer can be continuously used for a long time; on one hand, the outer side of the fluorescent protection layer is provided with the maintenance groove which is opposite to each insulation wire core, and the information label with the cable sheath thickness information is installed in the maintenance groove, so that the safety hazard of electric shock of pedestrians at night when the cable is drooping is avoided; therefore, the cable stripping position and the cable stripping depth of the cable during later-stage cable stripping maintenance can be accurately prompted, and the situation that the intact part in the cable is damaged due to the fact that the cable stripping cutter is inserted too deep during cable stripping maintenance during later-stage cable stripping maintenance of the cable is prevented.

Description

Technical Field

[0001] The utility model relates to the technical field of cables, and particularly relates to a new type of cable. Background Art

[0002] Cables are widely used in power supply systems, especially in long-distance power supply; as the carrier of the current power grid, cables are relatively expensive but essential facilities. Because of their high price, they are easily damaged or stolen; most traditional cables are wrapped with an outer rubber sleeve to wrap the internal wires, so it is very easy to cut the cable with scissors or pliers. At the same time, cables are mostly installed on utility poles or the outer surface of buildings. Cables often need to cross roads or alleys. After being broken by external forces, they will hang down or fall to the ground. At night, due to the lack of light, drivers and pedestrians cannot see the hanging or fallen wires. If they touch them, there may be an electric shock hazard.

[0003] In order to prevent the cable from being easily stolen during use and enable the cable to have a luminous warning function at night, a Chinese patent with the publication number CN205900143U discloses a new type of cable, including an inner wire, a shielding layer, an outer sheath, a synthetic fiber mesh layer, and a luminous layer; the inner wire is located inside the shielding layer, the outer sheath is wrapped around the outer periphery of the shielding layer, the synthetic fiber mesh layer is wrapped around the outer periphery of the outer sheath, the luminous layer is wrapped around the outer periphery of the synthetic fiber mesh layer, and an insulating core is arranged in the gap between the inner wire and the shielding layer.

[0004] Although the cable described in the above patent can prevent the cable from being easily cut and stolen by adding a synthetic fiber mesh layer during use, and can also use the luminous layer to give a luminous warning at night to avoid the safety hazard of electric shock caused by passing drivers or pedestrians touching the cable due to accidental drooping of the cable at night, the luminous layer of the cable with the above structure is directly installed on the outermost side of the cable during use, and the cable is directly exposed to the external environment during use, resulting in the luminous layer on the cable being damaged by long-term irradiation of ultraviolet rays, so that the cable loses the luminous warning function at night, and it is still easy to have the safety hazard of pedestrian electric shock at night when the cable is hanging low. At the same time, because the surface of the cable with the above structure is a smooth structure, it cannot give a prompt to the workers during the later cable stripping and maintenance, and it is easy for the cable stripping tool to be inserted too deep during the cable stripping and maintenance, thereby damaging the intact part inside the cable. Summary of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] The technical problem to be solved by the present utility model is to provide a novel cable aiming at the current situation of the prior art, which can not only protect the fluorescent layer to prevent the fluorescent layer from being easily damaged by ultraviolet irradiation during use, but also accurately prompt the stripping position and stripping depth on the cable during later wire stripping and maintenance.

[0007] (II) Technical solution

[0008] The present utility model is realized through the following technical solutions: The present utility model provides a novel cable, including a partition strip, on the outer wall of which four insulating wire cores are annularly installed. A shielding layer is wrapped outside the partition strip, an outer sheath is wrapped outside the shielding layer, a strengthening layer is wrapped outside the outer sheath, a fluorescent layer is wrapped outside the strengthening layer, a fluorescent protection layer is installed outside the fluorescent layer, and a maintenance slot is opened outside the fluorescent protection layer opposite to each insulating wire core, and an information label is installed in each maintenance slot.

[0009] Further, the partition strip is inserted into the insulating wire core, and the position of the partition strip opposite to the insulating wire core is an inward concave structure.

[0010] By adopting the above technical solution, the partition strip is mainly used to separate the insulating wire cores and prevent the mutual winding between the insulating wire cores.

[0011] Further, the shielding layer is bonded to the partition strip, and the partition strip is an insulating cotton strip.

[0012] By adopting the above technical solution, the shielding layer can shield and protect the insulating wire cores.

[0013] Further, the outer sheath is bonded to the shielding layer, and the outer sheath is a rubber sleeve.

[0014] By adopting the above technical solution, the outer sheath can provide insulation protection for the insulating wire cores.

[0015] Further, the strengthening layer is bonded to the outer sheath, and the strengthening layer is a synthetic fiber mesh layer.

[0016] By adopting the above technical solution, the strengthening layer can significantly improve the crack resistance of the cable, prevent the cable from being easily cut, and endow the cable with good anti-theft performance.

[0017] Further, the fluorescent protection layer is bonded to the fluorescent layer, and the fluorescent protection layer is made of a PC anti-ultraviolet film.

[0018] By adopting the above technical solution, the fluorescent layer can emit fluorescence at night, preventing potential safety hazards of pedestrian electric shock when the cable hangs low at night. The fluorescent protective layer can reduce the damage of ultraviolet rays to the fluorescent layer, ensuring the long-term stable use of the fluorescent layer.

[0019] Furthermore, the inspection groove is formed on the fluorescent protective layer, and the information label is adhered to the inspection groove.

[0020] By adopting the above technical solution, the inspection groove is mainly used to prompt the position of the insulated wire core, and the information label can prompt the stripping depth during the later stripping and maintenance of the cable.

[0021] (III) Beneficial Effects

[0022] The present utility model has the following beneficial effects compared with the prior art:

[0023] To solve the problem that although the existing cables can prevent the cables from being easily cut and stolen by adding a synthetic fiber mesh layer during use, and can also emit light for warning at night with the help of the luminous layer, avoiding potential safety hazards of electric shock caused by accidental drooping of the cable and touching the cable by passing drivers or pedestrians at night. However, in the cables with the above structure, the luminous layer is directly installed on the outermost side of the cable, and the cable is directly exposed to the external environment during use, resulting in the luminous layer on the cable being damaged by long-term irradiation of ultraviolet rays, so that the cable loses the function of luminous prompt at night, and still easily has potential safety hazards of pedestrian electric shock at night when the cable hangs low. At the same time, due to the smooth surface of the cables with the above structure, there is no prompt for workers during the later stripping and maintenance of the cable, and it is easy for the stripping tool to insert too deep during the stripping and maintenance of the cable, thereby damaging the intact part inside the cable. On the one hand, the present utility model installs a fluorescent protective layer made of PC anti-ultraviolet film outside the fluorescent layer, so that the cable can effectively reduce the damage of ultraviolet rays to the fluorescent layer under the action of the fluorescent protective layer during use, ensuring that the fluorescent layer can be continuously used for a long time and avoiding potential safety hazards of pedestrian electric shock when the cable hangs low at night. On the other hand, by opening an inspection groove on the outer side of the fluorescent protective layer opposite to each insulated wire core and installing an information label with the cable outer skin thickness information in the inspection groove, the stripping position and stripping depth during the later stripping and inspection of the cable can be accurately prompted, preventing the intact part inside the cable from being damaged due to the stripping tool inserting too deep during the later stripping and inspection of the cable.

The fluorescent layer 6 can emit fluorescence at night to prevent the safety hazard of pedestrians from getting an electric shock when the cable is hanging low at night. The fluorescent protective layer 7 can reduce the damage of ultraviolet rays to the fluorescent layer 6 and ensure the long-term stable use of the fluorescent layer 6. An inspection slot 8 is opened outside the fluorescent protective layer 7 opposite to each insulated wire core 1, and an information label 9 is installed in each inspection slot 8. The inspection slot 8 is mainly used to prompt the position of the insulated wire core 1, and the information label 9 can prompt the stripping depth during the later stripping and maintenance of the cable.

[0030] As Figure 1 - Figure 2 shown, in this embodiment, the partition strip 4 is inserted into the insulated wire core 1. The position of the partition strip 4 opposite to the insulated wire core 1 is an inward concave structure. The partition strip 4 is mainly used to separate the insulated wire cores 1 from each other to prevent the insulated wire cores 1 from being wound around each other. The shielding layer 2 is bonded to the partition strip 4. The partition strip 4 is an insulating cotton strip. The shielding layer 2 can shield and protect the insulated wire core 1. The outer sheath 3 is bonded to the shielding layer 2. The outer sheath 3 is a rubber sleeve. The outer sheath 3 can provide insulation protection for the insulated wire core 1.

[0031] As Figure 1 - Figure 2As shown, in this embodiment, the reinforcing layer 5 is bonded to the outer sheath 3.

The fluorescent protective layer 7 is bonded to the fluorescent layer 6. The fluorescent protective layer 7 is made of a PC anti-ultraviolet film. The inspection groove 8 is formed on the fluorescent protective layer 7, and the information label 9 is bonded to the inspection groove 8.

[0032] The specific implementation process of this embodiment is as follows: During use, first install the cable in the position where it is to be used, and then the cable can be put into use. During the use process, by installing the fluorescent protective layer 7 made of a PC anti-ultraviolet film outside the fluorescent layer 6, the cable can effectively reduce the damage of ultraviolet rays to the fluorescent layer 6 under the action of the fluorescent protective layer 7 during use, ensuring that the fluorescent layer 6 can be continuously used for a long time and avoiding the safety hazard of pedestrians getting electric shock at night when the cable is hanging low. At the same time, by opening an inspection groove 8 opposite each insulating wire core 1 on the outside of the fluorescent protective layer 7 and installing an information label 9 with the cable outer sheath thickness information in the inspection groove 8, the stripping position and stripping depth during the later cable stripping and maintenance can be accurately prompted, preventing damage to the intact part inside the cable due to the stripping tool being inserted too deep during the cable stripping and maintenance in the later stage.
