[0003] At present, the energy storage cable connection wires on the market are bare copper wire conductors twisted and then extruded with insulation. Among them, the insulation selected for the connection wires is PVC, TPE, chloroprene rubber, and XLPE. The working temperature of the above materials is between -15℃ and 90℃.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figures 1 to 4As shown, a cable structure for achieving heat dissipation during energy storage comprises a cable body 1, an insulating layer 2, a shielding layer 3, a protective layer 4, a heat-conducting sleeve 5, and a weather-resistant and wear-resistant protective sleeve 6 which are sequentially coated on the outside of the cable body 1, wherein the inside of the weather-resistant and wear-resistant protective sleeve 6 is uniformly provided with heat-conducting channels 7 along the circumferential direction, and the heat-conducting channels 7 are respectively connected to the heat-conducting sleeve 5 and the outside of the cable, and a blocking component is arranged on the weather-resistant and wear-resistant protective sleeve 6 and at the outer channel opening of the heat-conducting channel 7, and the heat-conducting channel 7 forms a closed space under the blocking of the blocking component and the heat-conducting sleeve 5, and when the closed space is heated and the air pressure increases, the blocking component is squeezed out to dissipate heat, and when the air pressure decreases, the blocking component is reset to maintain the blocked state.

[0027] As a further improvement of this embodiment, an extended heat-conducting portion 8 extending into the heat-conducting channel 7 is provided on the outer shell wall of the heat-conducting sleeve 5 , and heat can be effectively conducted into the heat-conducting channel through the extended heat-conducting portion 8 .

[0028] As a further improvement of this embodiment, the blocking component includes a blocking block 9 arranged at the outer channel opening of the heat-conducting channel 7, and a spring 10 is connected to the inner side of the blocking block 9, and the spring 10 can reset the blocking block 9 after the air pressure is reduced. A step groove 11 is arranged on the weather-resistant and wear-resistant protective cover 6 and located at the outer channel opening of the heat-conducting channel 7, and the inner contour of the blocking block 9 is adapted to the groove bottom shape of the step groove 11. A hollow connecting plate 12 is arranged inside the heat-conducting channel 7, and the other end of the spring 10 is connected to the hollow connecting plate 12. The hollow connecting plate 12 includes a connecting plate body 121 located in the middle, a connecting rod body 122 arranged around the connecting plate body 121 and connected to the side wall of the heat-conducting channel 7, and the spring 10 is connected to the connecting plate body 121. The diameter of the connecting plate body 121 is smaller than the diameter of the heat-conducting channel 7 to ensure that heat passes through the connecting plate body 121.

[0029] As a further improvement of this embodiment, guide rods 13 arranged parallel to the heat conduction channel 7 are provided at both ends of the inner side of the blocking block 9. A guide groove 14 cooperating with the guide rod 13 is provided on the step groove 11. The length dimension of the guide groove 14 is greater than the ejection distance dimension of the blocking block 9. Through the above technical solution, it can be ensured that the blocking block 9 still maintains a sliding connection relationship with the weather-resistant and wear-resistant protective cover 6 after being ejected.

[0030] The working principle and use process of this utility model:

[0031] Under normal working condition Figure 1As shown, the heat generated during the energy storage process will be absorbed and concentrated by the heat-conducting sleeve 5, and then transferred to the heat-conducting channel 7 through the extended heat-conducting portion 8. Since the heat-conducting channel 7 is a sealed space at this time, the air pressure inside it will gradually increase with the increase of temperature, and will squeeze the blocking block 9 to move outward. When the air pressure increases to the limit, the blocking block 9 will completely pop out of the step groove 11. At this time, the heat-conducting channel 7 will be connected to the outside of the cable to achieve heat dissipation. Figure 5 shown.

[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.

Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
