Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a fireproof and compression-resistant cable based on flame retardant materials. Background Art

[0002] As a key component for power transmission, cables are widely used. During the process of cable laying and installation, due to various terrains and landforms involved, most cables are often directly exposed. During daily use, it is inevitable that the internal lines will be damaged due to external impact and extrusion. For existing cables, due to structural limitations, it is very difficult to effectively protect the internal lines of the cables. Moreover, external lightning strikes and fires will also affect the normal use of the cables. Content of the Utility Model

[0004] An insulating outer layer, the cross-section of the insulating outer layer is sealed and made of PVC material;

[0005] A core, the core is located inside the insulating outer layer;

[0006] A compression-resistant device, the inner wall of the compression-resistant device is fixedly connected to the outer wall of the core, the compression-resistant device is located inside the insulating outer layer, and the compression-resistant device is spirally arranged along the outer wall of the core;

[0007] A flame retardant plug board is fixedly connected to the outside of the compression-resistant device, a honeycomb steel wire frame is fixedly connected to the inside of the compression-resistant device, and a live wire, a neutral wire and a ground wire are fixedly connected to the inner wall of the honeycomb steel wire frame.

[0008] Preferably, the compression-resistant device includes a support plate, an arc-shaped plate is fixedly connected to the outer wall of the support plate, elastic pieces are fixedly connected to the outer walls on both sides of the arc-shaped plate, and connecting rods are fixedly connected to both ends of the arc-shaped plate.

[0009] Preferably, the outer wall of the flame retardant plug board is fixedly connected to the inner wall of the insulating outer layer, and both ends of the live wire, the neutral wire and the ground wire are connected to an external circuit.

[0010] Preferably, the outer wall of the core is fixedly connected to the outer wall of the support plate, and through holes are formed in the wall of the arc-shaped plate.

[0012] The beneficial effects of the utility model are as follows:

[0013] The utility model reduces the impact of external pressure on the cable by setting a compressive device, utilizing the stability of a triangle and the arc structure of a Luer triangle, through a multi-layer compressive structure, and by the conversion and consumption of energy. At the same time, the flame-retardant inserts made of flame-retardant materials are arranged in a spiral pattern along with the compressive device, which can improve the fire resistance of the cable while ensuring that the cross-section of the cable is circular. The circular cross-section cable, combined with the lateral support of the Luer triangle and with the assistance of a honeycomb steel wire frame, prevents the cable from being overly flattened, causing local short circuits or short circuits, thereby extending the service life of the cable.

[0020] Embodiment:

[0021] Please refer to Figure 1 - Figure 4 , the utility model provides a technical solution: a fireproof and compressive cable based on flame-retardant materials, including:

[0022] An insulating outer layer 1, with a sealed cross-section and made of PVC material;

[0023] A battery cell 2, located inside the insulating outer layer 1;

[0024] The compression resistance device 3, the inner wall of the compression resistance device 3 is fixedly connected to the outer wall of the battery cell 2, the compression resistance device 3 is located inside the insulating outer layer 1, and the compression resistance device 3 is spirally arrayed along the outer wall of the battery cell 2;

[0025] A flame-retardant plug board 4 is fixedly connected to the outside of the compression resistance device 3, a honeycomb steel wire frame 5 is fixedly connected to the inside of the compression resistance device 3, and a live wire 6, a neutral wire 7 and a ground wire 8 are fixedly connected to the inner wall of the honeycomb steel wire frame 5.

[0026] The compression resistance device 3 includes a support plate 10, an arc plate 11 is fixedly connected to the outer wall of the support plate 10, elastic pieces 13 are fixedly connected to the outer walls on both sides of the arc plate 11, and connecting rods 12 are fixedly connected to both ends of the arc plate 11.

[0027] The outer wall of the flame-retardant plug board 4 is fixedly connected to the inner wall of the insulating outer layer 1, and both ends of the live wire 6, the neutral wire 7 and the ground wire 8 are connected to the external circuit.

[0028] The outer wall of the battery cell 2 is fixedly connected to the outer wall of the support plate 10, and through holes are formed in the wall of the arc plate 11.

[0029] The outer wall of the arc plate 11 is fixedly connected to the inner wall of the flame-retardant plug board 4, there are two groups of the live wire 6, the neutral wire 7 and the ground wire 8, and they are all arranged on both sides of the support plate 10.

[0030] Working principle:

[0031] When in use, the live wire 6, the neutral wire 7 and the ground wire 8 are connected to the external circuit, the outer insulating layer 1 is sleeved on the outside, the battery cell 2 plays the role of connecting and guiding each compression resistance device 3, the cross section of the flame-retardant plug board 4 is in a crescent shape, which can fill the gap between the insulating outer layer 1 and the compression resistance device 3 as much as possible, and moreover, each flame-retardant plug board 4 is arranged around the outer side wall of the arc plate 11 in the compression resistance device 3. Without affecting the normal use of the cable, through the circumferential arrangement, the protection area can be further increased. While the flame-retardant plug board 4 is flame-retardant, it assists in protecting against external impact forces, preventing the external force impact on the compression resistance device 3 from being too large. The honeycomb steel wire frame 5 supports the inside of the compression resistance device 3, and at the same time wraps the live wire 6, the neutral wire 7 and the ground wire 8. The support plate 10 inside the support device 3 is fixed to the battery cell 2, and the arc plate 11 at the other end of the support plate 10 is connected to each other through the connecting rods 12 and the elastic pieces 13 at its two ends. Since the cross section of the compression resistance device 3 is a Lorentz triangle, when the external pressure is too large, the pressure will be transmitted to the support plate 10 through the arc plate 11. The arc plate 11 adopts a mutually arc-shaped porous design, which can achieve lightweight weight reduction while ensuring the structural strength. At the same time, the porous design facilitates the timely discharge of heat when the live wire 6, the neutral wire 7 and the ground wire 8 are in abnormal contact. The connecting rods 12 and the elastic pieces 13 can assist the arc plate 11 to reset, convert a part of the external pressure into elastic potential energy and store it, and reduce the impact of the external force on the inside of the cable through energy consumption, thereby extending the service life of the cable.
