Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a light-emitting cable for a coal mining machine. Background Technology

[0002] In coal mining, the coal mining machine is a critical piece of equipment. Its cables not only need to transmit electrical energy but also possess properties such as abrasion resistance, tensile strength, and bending resistance to ensure the machine's normal operation. Traditional coal mining machine cables often focus only on conductivity and basic mechanical strength, neglecting aspects like lighting and abrasion resistance. Especially in dark or poorly lit coal mining environments, operators have difficulty clearly seeing their surroundings and the cable's condition, increasing safety risks. Utility Model Content

[0003] This application provides a light-emitting cable for coal mining machines to solve the problem that existing coal mining machine cables make it difficult to clearly see the surrounding environment and cable condition in dark or low-light coal mining environments.

[0004] This application provides a light-emitting cable for a coal mining machine, comprising:

[0005] The cable core includes a power core and a control core;

[0006] Inner sheath, which is fitted onto the cable core;

[0007] A light source layer, comprising: an LED light strip and a sheath, wherein the sheath is fitted onto the LED light strip, and several LED light strips fitted into the sheath are loosely wrapped around the inner sheath;

[0008] An outer protective layer is fitted onto the light source layer.

[0009] The beneficial effects of the above embodiments are as follows: by configuring a sheath to form a protective structure for the LED light strip, the service life of the LED light strip is improved; by the loosely wound LED light strip emitting light on the cable surface, the cable and its surrounding environment are illuminated, which greatly improves the usability of the coal mining machine cable in the mine.

[0010] Based on the above embodiments, the embodiments of this application can be further improved as follows:

[0011] In one embodiment of this application: the power core includes: a first conductor, a first insulating layer, and a shielding layer, wherein the first insulating layer is fitted onto the first conductor, and the shielding layer is fitted onto the first insulating layer. The beneficial effect of this step is that the shielding layer can effectively suppress electromagnetic interference.

[0012] In one embodiment of this application: the first conductor is a round conductor formed by repeatedly stranding fine tin-plated copper wires with a pitch of 10 to 14 times. The beneficial effect of this step is to improve the bending fatigue resistance of the first conductor.

[0013] In one embodiment of this application, the first insulation layer is a flame-retardant high-strength ethylene propylene rubber insulation material. The beneficial effect of this step is to improve the cable's heat resistance and fire resistance.

[0014] In one embodiment of this application, the shielding layer is a tin-plated copper wire braided structure. The beneficial effects of this step are: it can prevent external interference to the cable itself, and also prevent the cable itself from interfering with other electronic devices, while ensuring the cable's flexibility, achieving a dual unity of shielding and armoring.

[0015] In one embodiment of this application: the control core includes multiple stranded sub-cores, each sub-core comprising: a pad core, a second conductor, a second insulation layer, and a wrapping tape. The second conductor is wound around the pad core, the second insulation layer is fitted over the second conductor, and the wrapping tape is fitted over the outside of the stranded structure of the sub-core. The beneficial effects of this step are: the pad core improves the strength of the second conductor structure, and the wrapping tape winds the multiple sub-cores into an independent structure, ensuring the stability of the coal mining machine signal.

[0016] In one embodiment of this application, the inner sheath is made of flame-retardant high-strength chlorinated polyethylene material. The beneficial effect of this step is to improve the cable's heat resistance and fire resistance.

[0017] In one embodiment of this application, the outer sheath is made of an elastomeric material. The beneficial effects of this step are: improved cable flexibility, bending resistance, torsional rigidity, and abrasion resistance.

[0018] In one embodiment of this application, the sheath and the outer protective layer are transparent. The beneficial effect of this step is that it facilitates overall cable illumination. Attached Figure Description

[0024] like Figure 1 As shown, a coal mining machine luminescent cable includes: a cable core 1, an inner sheath 2, a light source layer 3, and an outer sheath 4. The cable core 1 includes a power core 101 and a control core 102. The inner sheath 2 is fitted onto the cable core 1. The light source layer 3 includes: an LED light strip 301 and a sheath 302. The sheath 302 is fitted onto the LED light strip 301. Several LED light strips 301 fitted into the sheath 302 are loosely wound around the inner sheath 2. The outer sheath 4 is fitted onto the light source layer 3.

[0025] In some embodiments of this application, such as Figure 1 As shown, there are three power cores 101. The power core 101 includes: a first conductor 1010, a first insulation layer 1011, and a shielding layer 1012. The first insulation layer 1011 is fitted onto the first conductor 1010, and the shielding layer 1012 is fitted onto the first insulation layer 1011. Electromagnetic interference can be effectively suppressed through the shielding layer 1012.

[0026] In some embodiments of this application, such as Figure 1As shown, the first conductor 1010 is made of multiple tin-plated soft copper wires twisted together, ensuring that the finished cable has good flexibility, bending resistance, torsion resistance and a long service life; the first insulation layer 1011 is extruded on the conductor, and the first shielding layer 1012 is a layer of tin-plated copper wire braided on the first insulation layer 1011; there is one control core 102, which is cabled separately and twisted together with the power core 101 to form the cable core 1; the inner sheath 2 is extruded on the cable core 1, the light source layer 3 is a structure in which multiple LED light strips 301, each extruded with a layer of silicone rubber, are loosely wound on the inner sheath 2, and the outer sheath 4 is extruded on the outside of the light source layer 3.

[0027] In some embodiments of this application, such as Figure 1 As shown, the first conductor 1010 is a round conductor formed by repeatedly twisting together multiple strands of fine tin-plated copper wire with a pitch of 10 to 14 times, thereby improving the bending fatigue resistance of the first conductor 1010.

[0028] In some embodiments of this application, such as Figure 1 As shown, the first insulation layer 1011 is a flame-retardant high-strength ethylene propylene rubber insulation material, thereby improving the cable's heat resistance and fire resistance.

[0029] In some embodiments of this application, such as Figure 1 As shown, the shielding layer 1012 is a tin-plated copper wire braided structure. This prevents external interference with the cable itself, as well as interference from the cable itself to other electronic devices, while also ensuring the cable's flexibility, achieving a dual unity of shielding and armoring.

[0030] In some embodiments of this application, such as Figure 1 As shown, the control core 102 includes multiple stranded sub-cores. Each sub-core includes: a pad core 1020, a second conductor 1021, a second insulation layer 1022, and a wrapping tape 1023. The pad core 1020 is a cylindrical rubber pad core 1020, specifically made of chlorinated polyethylene rubber or neoprene rubber. The second conductor 1021 is made of tin-plated copper wire and is wound around the pad core 1020. The pad core 1020 provides buffer support for each sub-core and enhances the overall torsional resistance. The second insulation layer 1022 is made of flame-retardant high-strength ethylene propylene rubber insulation material and is fitted onto the second conductor 1021. The wrapping tape 1023 is a polyester wrapping tape 1023, which is wound around the outside of the overall structure formed by the stranding of the sub-cores. The strength of the second conductor 1021 structure is improved by padding core 1020, and the multiple sub-cores 1 are wound into an independent structure by wrapping tape 1023 to ensure the stability of the coal mining machine signal.

[0031] In some embodiments of this application, such as Figure 1As shown, the inner sheath 2 is made of flame-retardant high-strength chlorinated polyethylene material, thereby improving the cable's heat resistance and fire resistance.

[0032] In some embodiments of this application, such as Figure 1 As shown, the outer sheath 4 is an elastomer material, such as polyurethane elastomer. The outer sheath 4 improves the cable's flexibility, bending resistance, torsional rigidity, and abrasion resistance.

[0033] In some embodiments of this application, such as Figure 1 As shown, the sheath 302 and the outer sheath 4 are transparent. Specifically, no color masterbatch is added during the manufacturing process of the sheath 302 and the outer sheath 4, making them transparent and allowing the light from the LED strip 301 to pass through the cable structure and illuminate the external environment.

[0034] In some embodiments of this application, the coal mining machine is powered by a cable, and the LED light strip is powered by a power source that supplies power to the cable.

[0035] This type of coal mining machine luminous cable, by configuring a sheath 302 to form a protective structure for the LED light strip 301, improves the service life of the LED light strip 301. The loosely wound LED light strip 301 emits light on the entire surface of the cable, producing the effect of illuminating the entire cable and the surrounding environment, which greatly improves the ease of use of the coal mining machine cable in the mine.
