Description

Technical Field

[0001] This utility model relates to the field of energy storage cable technology, specifically to a tensile-resistant and heat-dissipating energy storage cable. Background Technology

[0002] Energy storage cables are cables used in new energy power generation systems such as solar, wind, geothermal, and hydropower for energy storage, transfer, and distribution. They also refer to DC-side connection cables between battery clusters and between battery clusters and converters. In energy storage systems, cables are responsible for transmitting high-voltage DC power between battery modules and converters. They are the carriers of signals, data, and power transmission for the entire system, ensuring efficient and safe energy flow. Their performance directly affects the stability and safety of the entire system.

[0003] Currently, energy storage cables lack tensile heat dissipation structures. These cables are easily stretched by external forces during use, but their inherent tensile strength is poor, leading to localized deformation and eventual breakage. Furthermore, the large amount of heat generated during operation accumulates internally, and the difficulty in quickly dissipating this heat shortens their lifespan. Therefore, this paper proposes a tensile-resistant and easily heat-dissipating energy storage cable. This cable incorporates a tensile heat dissipation structure, utilizing sleeves, elasticity, and support to reduce localized deformation caused by external pulling, thereby improving its tensile strength. Simultaneously, heat conduction and ventilation are used for auxiliary heat dissipation, thus enhancing the overall performance. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a tensile-resistant and heat-dissipating energy storage cable, which reduces local deformation caused by external pulling force, improves its tensile strength, and thus improves its performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is a tensile-resistant and heat-dissipating energy storage cable, including a cable and a positioning component, wherein the positioning component is sleeved on the periphery of the cable;

[0006] The cable includes a first sheath, and a second sheath is wrapped around the first sheath. An elastomer is disposed at equal intervals between the second sheath and the first sheath, and the surface of the second sheath is provided with heat dissipation micropores.

[0007] By adopting the above technical solution, an auxiliary tensile heat dissipation structure is added, and elastic support and elastic deformation are used to reduce the tensile deformation caused by the cable itself being pulled.

[0008] Specifically, the positioning component includes a base plate, a fixing sleeve is bolted to the top of the base plate, and a connecting cable is sleeved on the fixing sleeve. The surface of the base plate has mounting holes.

[0009] Specifically, the elastomer is a thermoplastic elastomer, and the second sheath is made of silicone rubber.

[0010] Specifically, a fixing ring is provided on the outer side of the fixing sleeve, and a spring is provided between the fixing sleeve and the fixing ring, with both ends of the spring being fixedly connected to the fixing sleeve and the fixing ring through reserved slots.

[0011] Specifically, a conductor is disposed inside the first sheath, an insulating layer is disposed around the conductor, a filling layer is disposed between the conductor and the insulating layer, and a shielding layer is disposed between the first sheath and the insulating layer.

[0012] The beneficial effects of this utility model are:

[0013] (1) The tensile and heat-dissipating energy storage cable described in this utility model can increase the auxiliary tensile and heat dissipation structure by setting the first sheath, the second sheath, the elastomer and the heat dissipation micropores. By using elastic support and elastic deformation, the tensile deformation caused by the cable itself being pulled is reduced, thereby improving the tensile and heat dissipation performance of the energy storage cable and improving the actual use quality and effect.

[0014] (2) The tensile-resistant and heat-dissipating energy storage cable described in this utility model can increase the auxiliary positioning structure by setting the base plate, fixing sleeve, mounting hole, fixing ring and spring. By using the fixed length positioning method, the movement and deformation of the cable can be restricted, so that the tension can be distributed more evenly in all parts of the cable, avoiding damage caused by excessive local stress. At the same time, the spring force can be used to assist in the reset of the stretched parts, thereby improving the flexibility and stability of installation and use. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] To reduce localized deformation caused by external pulling forces, improve its tensile strength, and thus enhance its performance, such as... Figure 1-3 As shown, the present invention provides a tensile-resistant and heat-dissipating energy storage cable, which includes a cable 1 and a positioning component 2, wherein the positioning component 2 is sleeved around the cable 1.

[0024] The cable 1 includes a first sheath 101, and a second sheath 102 is wrapped around the first sheath 101. An elastomer 103 is equidistantly disposed between the second sheath 102 and the first sheath 101. The surface of the second sheath 102 is provided with heat dissipation micropores 104.

[0025] In use, the first sheath 101, the second sheath 102, the elastomer 103 and the heat dissipation micropores 104 can increase the auxiliary tensile heat dissipation structure, and reduce the tensile deformation caused by the cable itself being pulled by elastic support and elastic deformation.

[0026] To improve stability in use, for example, such as Figure 1 , Figure 4 As shown, the present invention also includes a positioning component 2 comprising a base plate 201, a fixing sleeve 202 connected to the top of the base plate 201 by bolts, and the fixing sleeve 202 being sleeved with a connecting cable 1, and an installation hole 203 being provided on the surface of the base plate 201.

[0027] During use, the base plate 201, fixing sleeve 202 and mounting hole 203 can be used to limit the movement and deformation of the cable by means of fixed length positioning, so that the tension can be distributed more evenly in all parts of the cable, avoiding damage caused by excessive local stress.

[0028] For example, such as Figure 2 As shown, the present invention also includes that the elastomer 103 is a thermoplastic elastomer and the second sheath 102 is made of silicone rubber.

[0029] During use, the elastic deformation properties of the elastomer 103 and the second sheath 102 can reduce the deformation of the cable 1 caused by external pulling force, thereby improving the stability and safety of use.

[0030] For example, such as Figure 4 As shown, the present invention also includes a fixing ring 204 provided on the outer side of the fixing sleeve 202, a spring 205 provided between the fixing sleeve 202 and the fixing ring 204, and both ends of the spring 205 are fixedly connected to the fixing sleeve 202 and the fixing ring 204 through reserved slots.

[0031] During use, the retaining ring 204 and spring 205 can be used to drive the cable to retract and reset, reducing the deformation caused by the external force pulling the cable 1 and further improving the tensile strength of the cable 1.

[0032] For example, such as Figure 5 As shown, the present invention also includes a conductor 105 disposed inside the first sheath 101, an insulating layer 106 disposed around the conductor 105, a filling layer 107 disposed between the conductor 105 and the insulating layer 106, and a shielding layer 108 disposed between the first sheath 101 and the insulating layer 106.

[0033] In use, the conductor 105, insulation layer 106, filling layer 107 and shielding layer 108 can form an energy storage cable with the first sheath 101.

[0034] When using this utility model, the operator can first fix the cable 1 in advance according to the installation location and environment, and fix it in place with screws through the mounting holes 203 of the base plate 201. When the cable 1 is pulled by an external force, the second sheath 102 and the elastic body 103 can generate elastic deformation under the action of the tension in advance, thereby reducing the effect of the tension on the first sheath 101. At the same time, the heat dissipation micro-holes 104 on the outer surface can be used to assist in the heat dissipation of the heat generated inside the cable 1, thereby improving the stability and safety of use.

[0035] Furthermore, the base plate 201 and the fixing sleeve 202 can be used to limit the movement and deformation of the cable by pre-setting the length. When a pulling force is received, the pulling force can be distributed more evenly to various parts of the cable, avoiding damage caused by excessive local force. At the same time, the spring 205 and the fixing ring 204 can be used to pull the cable 1 pulled by the elastic force to assist in retraction and reset, thereby further reducing the deformation caused by external pulling force. The overall structure is simple, low cost, and more stable and reliable in use.
