Description

Technical Field

[0001] The utility model relates to the field of cables, and in particular to an energy storage cable. Background Art

[0002] Energy storage cables refer to cables used for energy storage, transfer and distribution in new energy power generation systems such as solar energy, wind energy, geothermal energy, and hydropower. It includes battery packs, energy storage inverters, AC boundary points, substations and other corresponding equipment, which can effectively store clean energy from unconventional new energy power generation, and provide a stable, efficient and green supply for the energy needs of modern life and industry. Energy storage cables usually need to have high voltage characteristics, fire resistance, mechanical wear resistance, corrosion resistance and other characteristics. At the same time, energy storage cables also need a certain degree of compression resistance. When heavy objects are pressed on the cable, it may cause damage to the inner core of the internal cable, affecting the transmission efficiency and reducing safety. However, most of the existing energy storage cables do not have a compression-resistant structure, which may reduce the stability and service life of the energy storage cables during use.

[0003] How to invent an energy storage cable to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides an energy storage cable, which aims to improve the energy storage cable which requires a certain degree of pressure resistance. When a heavy object presses on the cable, it may cause damage to the inner core of the cable, affecting the transmission efficiency and reducing safety. However, most of the existing energy storage cables do not have a pressure-resistant structure, which may reduce the stability and service life of the energy storage cable during use.

[0005] The utility model is implemented as follows: an energy storage cable, including an outer protective wear-resistant layer, a cable inner core is arranged inside the outer protective wear-resistant layer, and several layers of packaging materials are arranged between the outer protective wear-resistant layer and the cable inner core. Several supporting and pressure-resistant components are evenly arranged on the outer wall of the outer protective wear-resistant layer, and each of the supporting and pressure-resistant components includes an outer shell, which is a hollow annular structure, and several V-shaped support members are annularly distributed and integrated between the curved inner walls on both sides of the outer shell.

[0006] In a preferred technical solution of the utility model, a plurality of through holes are annularly distributed on the outer wall of the shell, a threaded connection sleeve is fixedly connected in each of the through holes, and a sealing bolt is threadedly connected in each of the threaded connection sleeves.

[0007] In a preferred technical solution of the present utility model, each of the threaded connection sleeves is located at an opening on one side of the corresponding V-shaped support member.

[0008] In a preferred technical solution of the present invention, an elastic limiting member is fixedly connected between the opposite side surfaces of every two adjacent V-shaped supporting members.

[0009] In a preferred technical solution of the utility model, a fastening and limiting layer is provided outside the cable inner core and inside the outer protective wear-resistant layer.

[0010] In a preferred technical solution of the utility model, a heat insulation layer is provided outside the fastening and limiting layer and inside the outer protective wear-resistant layer.

[0011] In a preferred technical solution of the utility model, an anti-corrosion layer is provided outside the heat-insulating layer and inside the outer protective wear-resistant layer.

[0012] The beneficial effect of the utility model is that the utility model obtains an energy storage cable through the above-mentioned design. When in use, the supporting pressure-resistant components are integrally arranged on the outer wall of the outer protective wear-resistant layer, which can effectively increase the supporting points of the energy storage cable and reduce the contact area between the outer wall of the cable and the outside, thereby reducing the wear. At the same time, the intervals between the supporting pressure-resistant components can be set according to the use environment. When a heavy object presses on the cable, the supporting pressure-resistant components can also be used to support the heavy object, thereby improving the overall pressure resistance of the cable and improving the stability and service life of the energy storage cable during use.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 6 The utility model provides a technical solution: an energy storage cable, including an outer protective wear-resistant layer 2, a cable inner core 1 is arranged inside the outer protective wear-resistant layer 2, and several layers of packaging material are arranged between the outer protective wear-resistant layer 2 and the cable inner core 1. Several supporting and pressure-resistant components 3 are evenly arranged on the outer wall of the outer protective wear-resistant layer 2, and each supporting and pressure-resistant component 3 includes an outer shell 301, and the outer shell 301 is a hollow annular structure. Several V-shaped support members 302 are distributed in an annular manner between the curved inner walls on both sides of the outer shell 301.

[0023] It should be noted that the outer shell 301 and the V-shaped support member 302 are both made of relatively hard rubber material. When the outer shell 301 is subjected to pressure as a whole, the outer shell 301 and the V-shaped support member 302 can be deformed to protect the entire cable to a certain extent.

[0024] See also Figure 3 and Figure 4 A plurality of through holes are arranged in an annular pattern on the outer wall of the housing 301 , a threaded connection sleeve 303 is fixedly connected to each through hole, and a sealing bolt 304 is threadedly connected to each threaded connection sleeve 303 .

[0025] When laying cables and connecting several cables, the sealing bolts 304 can be removed, and the two housings 301 can be connected by stud bolts or the housings 301 can be installed on a support, thereby improving the convenience of laying cables and connecting cables.

[0026] Furthermore, each threaded connection sleeve 303 is located at an opening on one side of the corresponding V-shaped support member 302 .

[0027] The threaded connection sleeve 303 is located at an opening on one side of the corresponding V-shaped support member 302, so when the sealing bolt 304 and the stud bolt are connected in the threaded connection sleeve 303, the supporting effect of the V-shaped support member 302 will not be affected, thereby providing stability during use.

[0028] See also Figure 5 and Figure 6 An elastic limiting member 305 is fixedly connected between the opposite side surfaces of each two adjacent V-shaped supporting members 302 .

[0029] The elastic limiter 305 can support and limit the corresponding two V-shaped support members 302. The elastic limiter 305 is a whole of four integrally formed plate-like structures. One side surface of each flat plate is in contact with one side surface of the corresponding V-shaped support member 302, and the angle between the two flat plates at the same end is less than 90°. When the shell 301 is under pressure and the corresponding V-shaped support member 302 is deformed to both sides and the angle increases, it will directly squeeze the elastic limiter 305 on both sides. The elastic limiter 305 further supports the surfaces on both sides of the V-shaped support member 302. After the pressure is released, the elastic limiter 305 itself has elasticity and can quickly reset the V-shaped support member 302. The material of the elastic limiter 305 can be metal or plastic.

[0030] See also Figure 1 A fastening and limiting layer 6 is provided outside the cable inner core 1 and inside the outer protective wear-resistant layer 2 .

[0031] The tightening and limiting layer 6 is an insulating packaging material tightly wrapped around the outside of the cable core 1. While playing the role of insulation to improve the conduction safety, it can also increase the interface pressure between the cable cores 1, reduce the occurrence of discharge, and further improve the overall conduction efficiency of the cable.

[0032] Furthermore, a heat insulation layer 5 is provided outside the fastening and limiting layer 6 and inside the outer protective wear-resistant layer 2 .

[0033] The heat insulation layer 5 is located outside the fastening and limiting layer 6 to play a role in fire prevention and temperature insulation, thereby preventing the cable conduction efficiency from being affected under high temperature conditions and improving the safety of use to a certain extent by flame retardancy.

[0034] Furthermore, an anti-corrosion layer 4 is provided outside the heat-insulating layer 5 and inside the outer protective wear-resistant layer 2 .

[0035] The anti-corrosion layer 4 located on the second outer side can reduce the corrosion of the external environment to the internal packaging material and the cable core 1, thereby extending the overall service life of the cable. At the same time, protecting the anti-corrosion layer 4 through the outer protective wear-resistant layer 2 can reduce the wear of the anti-corrosion layer 4 and improve the overall corrosion resistance.

[0036] Working principle: The support and pressure-resistant components 3 are integrally arranged on the outer wall of the outer protective wear-resistant layer 2, which can effectively increase the support points of the energy storage cable and reduce the contact area between the outer wall of the cable and the outside, thereby reducing wear. At the same time, the intervals between the support and pressure-resistant components 3 can be set according to the use environment. When a heavy object presses on the cable, the support and pressure-resistant components 3 can also be used to support the heavy object. After the outer shell 301 is compressed, the outer wall is deformed to compress the corresponding V-shaped support member 302 inside. The V-shaped support member 302 opens to both sides to compress the elastic limit member 305. When the pressure is released, the V-shaped support member 302 is reset under the elastic action of the elastic limit member 305, thereby improving the overall pressure resistance of the cable and ensuring the stability and service life of the energy storage cable during use.

[0037] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
