In this case, photovoltaic cables need to be buried over long distances. Due to the long burial distance, the environmental factors of the areas through which the photovoltaic cables pass are also different. Therefore, photovoltaic cables are required to have excellent properties such as high temperature resistance, corrosion resistance, wear resistance, flame retardancy and environmental protection.

The balls 8105 arranged in the longitudinal protection component 81 and the curved protection component 82 are rolled on the ground to prevent the surface of the cable from directly contacting the ground. In combination with the protection of the longitudinal protection component 81 and the curved protection component 82, the surface of the cable can be protected. The balls 8105 roll on the ground, which can effectively reduce the force used to drag the cable and reduce labor.

[0024] like Figure 3 and Figure 5 In the figure, the longitudinal protection component 81 includes a rubber fixing strip 8101, which is fixed on the outer wall of the outer layer component 7. The rubber fixing strip 8101 is provided with an embedding groove 8102, in which an embedding rubber strip 8103 is installed, and the ball 8105 is rollingly installed on the embedding rubber strip 8103. By rollingly installing the ball 8105 on the embedding rubber strip 8103, the ball 8105 can be replaced when it falls off or is excessively worn, thereby ensuring the wear-resistant protection effect of the external protection component 8 on the cable.

Since the cross-section of the photovoltaic cable is circular, the edges of the cross-section of the raised rib 8303 and the embedded rubber strip 8103 should be arranged on the outer wall of the cable. It is in the shape of an arc, and the above-mentioned outer diameter is the enclosed outer diameter formed by the raised ribs 8303 and the embedded rubber strip 8103 respectively. The protective plates 8301 are staggered between the curved protective components 82 to protect the exposed surface of the cable and prevent the surface of the cable from being worn and cracked due to the protrusion of foreign objects. When the embedded rubber strip 8103 falls off or is excessively worn, the protective plate 8301 will contact the ground, and the protective plate 8301 will make a sound due to friction when moving on the ground, thereby achieving the purpose of warning and reminding people to replace and repair the embedded rubber strip 8103 around the sound-producing part in time.

[0028] like Figure 1-Figure 3 In the embodiment, the cable assembly 2 includes a cable core 21, an insulating layer 22 is arranged on the outside of the cable core 21, and the insulating layer 22 is embedded and fixed on the supporting assembly 1. The insulating layer 22 is used to insulate and protect the cable core 21 to ensure the normal use of the cable.

[0029] like Figure 1 In the embodiment, a shielding layer 5 is glued inside the outer layer component 7, a protective net structure layer 6 is arranged between the outer layer component 7 and the shielding layer 5, a waterproof layer 4 is glued inside the shielding layer 5, an armor layer 3 is glued inside the waterproof layer 4, and the supporting component 1 is located inside the armor layer 3. The armor layer 3, the waterproof layer 4, the shielding layer 5 and the protective net structure layer 6 are utilized to ensure the normal use effect of the cable and the structural strength of the cable.

[0030] like Figure 2 , Figure 3 , Figure 4 ,and Figure 6In the embodiment, the support assembly 1 comprises a support shell 11, wherein three inner cavities 17 are arranged in the support shell 11, and three positioning grooves 12 are arranged equally on the outer side of the support shell 11, and the three cable assemblies 2 are respectively fixed in the three positioning grooves 12; the outer sides of the three cable assemblies 2 are respectively provided with a No. 2 heat conducting plate 15 which fits with each other, and the outer sides of the three No. 2 heat conducting plates 15 are respectively fixed with a No. 2 pillar 16, and the end of the No. 2 pillar 16 sequentially penetrates the armor layer 3, the waterproof layer 4, the shielding layer 5, the protective net structure layer 6 and the outer layer assembly 7 and is fixed on the longitudinal protection assembly 81, and the three inner cavities 17 are respectively provided with a No. 1 heat conducting plate 13, and the No. 1 heat conducting plate 15 is arranged on the outer side of the three cable assemblies 2, and the No. 2 pillar 16 is respectively fixed on the outer side of the three No. 2 heat conducting plates 15. A No. 1 pillar 14 is fixedly connected to the outer side of the No. 1 heat-conducting plate 13, and the end of the No. 1 pillar 14 passes through the supporting shell 11, the armor layer 3, the waterproof layer 4, the shielding layer 5, the protective net structure layer 6 and the outer layer component 7 in sequence and is fixed to the protective plate 8301. The gap between the supporting shell 11 and the armor layer 3 and the inner cavity 17 are filled with solid particles with lightweight thermal conductivity properties. By filling the gap between the supporting shell 11 and the armor layer 3 and the inner cavity 17 with solid particles with lightweight thermal conductivity properties, the weight of the cable is reduced by filling the particles, and the heat generated by the cable assembly 2 during use can be discharged by utilizing the filling particles, so as to increase the service life of the cable.

[0031] During operation, the photovoltaic cable will be dragged and moved when buried, and the outer layer of the existing photovoltaic cable is mainly protected by a rubber outer layer. The outer layer of the photovoltaic cable is easily worn and broken during dragging and moving, thereby reducing the protective effect of the cable, resulting in poor wear resistance and protection of the cable. The rupture of the outer layer of the photovoltaic cable will affect the normal use of the cable. In this solution, the longitudinal protection component 81 is fixed along the cable setting direction, and the curved protection component 82 is set between the longitudinal protection components 81. The longitudinal protection component 81 and the curved protection component 82 are used to support the cable, so that the cable is kept at a certain distance from the ground or foreign objects to avoid direct wear on the outer layer of the cable, and the spacer component 83 is used to fill the gap of the curved protection component 82 to prevent the protrusion or foreign objects from contacting the outer layer of the cable and causing damage to the cable, thereby fully protecting the cable. When the cable is dragged and moved, since the curved protection component 82 and the longitudinal protection component 81 have the same internal component settings, the curved protection component 82 and the longitudinal protection component 81 are both provided with rubber fixing strips 8101, interlocking grooves 8102, interlocking rubber strips 8103, fixed shells 8104, balls 8105, fixed rib grooves 8106 and fixed ribs 8107, and the component installation methods are consistent, and all meet the requirement that the balls 8105 can roll in the fixed shell 8104. When the photovoltaic cable is dragged, the balls 8105 in the longitudinal protection component 81 and the curved protection component 82 will roll in the fixed shell 8104, and the smoothness of the rolling of the balls 8105 is ensured under the action of the fixed shell 8104, so as to reduce the force used to drag the cable, thereby achieving the effect of labor saving. Regardless of the angle or dragging method of the cable, the longitudinal protection component 81 and the curved protection component 82 can always contact the ground, thereby avoiding the outer layer of the photovoltaic cable from being worn, thereby achieving the effect of cable wear protection. When the ball 8105 is damaged and falls off from the fixed shell 8104 or the embedded rubber strip 8103 is excessively worn, the raised rib 8303 will touch the ground. At this time, the protective plate 8301 will make a sound due to the friction between the raised rib 8303 and the ground during the dragging of the cable, so as to achieve the function of prompting, so that people can repair the part that makes the sound in time, and ensure that the external protective component 8 can continue to protect the cable, so as to ensure the wear-resistant protection effect of the cable; During repair, the damaged embedded rubber strip 8103 is removed from the embedded groove 8102, and the complete embedded rubber strip 8103 is reinstalled in the embedded groove 8102, and the fixing ribs 8107 on both sides of the embedded rubber strip 8103 are respectively embedded in the fixing rib grooves 8106 to fix the embedded rubber strip 8103; By arranging the metal corrugated sheet 73 and the steel wire 75 in the outer rubber layer 71 and the inner rubber layer 72, the outer layer structural strength of the photovoltaic cable is improved, and the cable is prevented from being directly worn and broken after the longitudinal protection component 81, the curved protection component 82 and the spacing component 83 are damaged and fall off, so as to further improve the wear-resistant protection effect of the outer layer of the cable; By fixing the cable assembly 2 in the positioning groove 12, the heat generated by the cable during use will be absorbed by the filling particles and conducted outwardly, and the heat of the cable is absorbed by the No. 1 pillar 14, the No. 2 pillar 16, the No. 1 heat conducting plate 13 and the No. 2 heat conducting plate 15, and the heat is dissipated outwardly through the protective plate 8301 and the longitudinal protective assembly 81, so as to achieve the effect of heat dissipation, and the support shell 11 is supported and fixed by the No. 1 pillar 14, and the No. 2 pillar 16 fixes the cable assembly 2, so as to ensure the structural stability of the cable; The combination achieves the effect of wear-resistant protection of photovoltaic cables. Compared with traditional photovoltaic cables, the wear-resistant effect is better, and the wear-resistant protection effect of photovoltaic cables is effectively improved.
