Description

Technical Field

[0001] This utility model relates to the field of power cable technology, specifically to a protective power cable. Background Technology

[0002] Power cables are core electrical equipment used for transmitting and distributing electrical energy. They are widely used in power systems, industrial production, construction projects, transportation facilities, and other scenarios, serving as the "power blood vessels" connecting power plants, substations, and distribution stations with electrical equipment. Through structural designs such as insulation layers, shielding layers, and sheathing layers, they ensure electrical safety while achieving stable transmission of high voltage and high current. Compared to overhead power lines, they have advantages such as smaller footprint, less susceptibility to environmental influences, and higher safety.

[0003] In existing technologies, protective power cables are installed with protective iron shells in some complex terrains. Traditional protective devices cannot be changed according to the folding of the cable. When the cable routing needs to be bent and adjusted, the protective shell cannot bend synchronously, which will form a rigid pull or gap with the cable. Not only will it fail to fit and wrap the cable, but it may also squeeze the cable insulation layer, damaging the original structure of the cable. The gaps will allow dust, moisture, oil and other contaminants to enter, accelerating the aging of the cable. It may also allow foreign objects to touch the cable conductor, increasing the risk of short circuits and leakage. If used in mobile equipment or dynamic wiring scenarios, the forced misalignment between the protective shell and the cable will repeatedly wear down the cable, shortening its service life. It is not practical enough. It not only limits the flexibility of cable routing and cannot meet the installation requirements of complex paths, but may also cause the protective shell itself to crack or fall off due to forced adaptation, losing its protective function and increasing the cost of later maintenance and replacement. Utility Model Content

[0004] The purpose of this utility model is to provide a protective power cable to solve the problem mentioned in the background art that the protective power cable cannot be folded according to the folding of the cable, which leads to the destruction of the original structure of the cable, thus limiting the wiring flexibility of the cable and increasing the cost of later maintenance and replacement.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a protective power cable, including a cable jacket, an annular sleeve movably connected to the cable jacket, a mounting protective seat fixedly connected to the annular sleeve, a cable body disposed inside the cable jacket, a fixing component disposed on the mounting protective seat, a protective component disposed inside the cable jacket, a fixing bolt threadedly connected inside the mounting protective seat, a first adjusting bracket and a second adjusting bracket slidably connected inside the mounting protective seat, a sliding fixing plate fixedly connected to the first adjusting bracket and the second adjusting bracket, the sliding fixing plate slidably connected inside the mounting protective seat, the first adjusting bracket rotatably connected to the second adjusting bracket, and when the cable jacket needs to be folded, the annular sleeve slides on the cable jacket by pulling the mounting protective seat and the other mounting protective seat, causing the first adjusting bracket and the second adjusting bracket to protrude, and the rotation adjustment between the mounting protective seats is achieved by rotating the first adjusting bracket on the second adjusting bracket.

[0006] In the preferred embodiment of this technical solution, the protective mounting base has a sliding groove at the corresponding position of the second adjusting bracket and the first adjusting bracket, and the second adjusting bracket and the first adjusting bracket slide inside the sliding groove.

[0007] In the preferred embodiment of this technical solution, the protective mounting base has a groove at the corresponding position of the sliding fixing plate, and the sliding fixing plate slides inside the groove.

[0008] In the preferred embodiment of this technical solution, the protective mounting base is provided with a locking block inside the slide groove of the first adjusting bracket and the second adjusting bracket, and the sliding fixing plate contacts the locking block.

[0009] According to the preferred embodiment of this technical solution, the fixing component includes a return spring and an elastic pad disposed between the annular sleeve and the mounting protective seat, a slot opened inside the mounting protective seat, a limiting soft frame fixedly connected to one end of the mounting protective seat, and the limiting soft frame being snapped into the inside of the slot, thereby realizing the connection between the mounting protective seats by the limiting soft frame being snapped into the inside of the slot.

[0010] Based on the preferred embodiment of this technical solution, the limiting soft frame is provided with a protrusion, and the slot has a slot at the position of the protrusion, and the protrusion is engaged inside the slot.

[0011] Based on the preferred embodiment of this technical solution, the protective component includes a fixed bracket fixedly connected to the outside of the cable body, ceramic fiber disposed inside the fixed bracket, a high-temperature resistant layer fixedly connected to the fixed bracket, elastic beads disposed on the high-temperature resistant layer, a heat-conducting layer disposed on the elastic beads, a heat-dissipating layer disposed on the heat-conducting layer, a protective steel wire disposed outside the heat-dissipating layer, and an outer protective layer disposed between the protective steel wire and the cable jacket.

[0012] Based on the preferred embodiment of this technical solution, a number of elastic beads are provided, and the number of elastic beads are evenly disposed between the high-temperature resistant layer and the heat-conducting layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By pulling the protective base, the ring sleeve slides along the cable sheath, exposing the first and second adjustment brackets. Utilizing their rotational characteristics, the protective base can rotate at multiple angles, avoiding the rigid pulling of traditional protective shells on cables, preventing insulation damage and structural damage. There are no bends or gaps, which can block dust and moisture intrusion, slow down cable aging, reduce the risk of short circuits and leakage, adapt to complex terrain and dynamic wiring scenarios, avoid forced misalignment of the protective shell to avoid cable wear, extend service life, and reduce the need for forced adaptation, thus reducing the problem of protective shell cracking and falling off, lowering later maintenance and replacement costs, and meeting the installation requirements of complex paths.

[0014] 2. The fixed bracket provides stable support for the cable body, ensuring that the internal structure is not easily deformed under stress or bending. The inner ceramic fiber and high-temperature resistant layer are superimposed, greatly improving the cable's high-temperature resistance. It can adapt to high-temperature environments or cable overload heating scenarios, preventing the insulation layer from failing due to high-temperature aging. The evenly distributed elastic beads can buffer external impacts in all directions. No matter which direction the external force comes from, it can absorb energy through deformation, reducing damage to the cable body. It is especially suitable for scenarios with mechanical vibration or collision risks. The heat-conducting layer and heat-dissipating layer work together to quickly dissipate the heat generated during operation, preventing high temperature accumulation from affecting cable performance. The protective steel wire enhances the overall tensile and puncture resistance, resisting scratches or punctures from external sharp objects. The outer protective layer provides an additional barrier for the cable jacket. The superposition of multiple protections not only ensures the structural integrity of the cable in complex environments but also extends its service life, adapting to a variety of harsh scenarios.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 This utility model provides an embodiment including a cable jacket 1, an annular sleeve 2 movably connected to the cable jacket 1, a mounting protective seat 3 fixedly connected to the annular sleeve 2, a cable body 4 disposed inside the cable jacket 1, a fixing component disposed on the mounting protective seat 3, a protective component disposed inside the cable jacket 1, a fixing bolt 801 threadedly connected inside the mounting protective seat 3, a first adjusting bracket 802 and a second adjusting bracket 803 slidably connected inside the mounting protective seat 3, and a sliding fixing plate 806 fixedly connected to the first adjusting bracket 802 and the second adjusting bracket 803. The sliding fixing plate 806 is slidably connected to... Inside the mounting protective seat 3, the first adjusting bracket 802 is rotatably connected to the second adjusting bracket 803. When the cable sheath 1 needs to be folded, the mounting protective seat 3 and the other mounting protective seat 3 are pulled together, causing the annular sleeve 2 to slide on the cable sheath 1, thus exposing the first adjusting bracket 802 and the second adjusting bracket 803. The rotation of the first adjusting bracket 802 on the second adjusting bracket 803 achieves rotational adjustment between the mounting protective seats 3. External force is applied to the mounting protective seat 3, causing the annular sleeve 2 to slide along the cable sheath 1, exposing the previously hidden first adjusting bracket 802 and the second adjusting bracket 803. At this time, utilizing the rotational connection characteristic of the first adjusting bracket 802 and the second adjusting bracket 803, multi-angle rotation of adjacent mounting protective seats 3 can be achieved, meeting the cable bending requirements.

[0019] Please see Figure 2-4A further solution based on this embodiment is as follows: the mounting protective seat 3 has a sliding groove at the corresponding position of the second adjusting bracket 803 and the first adjusting bracket 802. The second adjusting bracket 803 and the first adjusting bracket 802 slide inside the sliding groove. By setting a sliding groove on the mounting protective seat 3 that is adapted to the second adjusting bracket 803 and the first adjusting bracket 802, precise guidance is provided for the sliding of the bracket, avoiding the second adjusting bracket 803 and the first adjusting bracket 802 from shifting or getting stuck during the adjustment process, and ensuring smooth connection between the sliding of the annular sleeve 2 and the rotation of the bracket.

[0020] Please see Figure 2-4 A further solution based on this embodiment is as follows: the protective mounting base 3 has a groove at the corresponding position of the sliding fixing plate 806, and the sliding fixing plate 806 slides inside the groove. By setting a dedicated groove for the sliding fixing plate 806, the sliding fixing plate 806 maintains a stable trajectory when it moves with the first adjusting bracket 802 and the second adjusting bracket 803, avoiding the loosening of the bracket connection caused by the offset of the sliding fixing plate 806. At the same time, the tight fit between the groove and the sliding fixing plate 806 can disperse some of the external force and reduce the load-bearing pressure of the first adjusting bracket 802 and the second adjusting bracket 803.

[0021] Please see Figure 2-4 A further solution based on this embodiment is as follows: the mounting protective seat 3 is provided with a locking block inside the slide groove of the first adjusting bracket 802 and the second adjusting bracket 803, and the sliding fixing plate 806 contacts the locking block. By setting the locking block in the slide groove and contacting the sliding fixing plate 806, the sliding range of the first adjusting bracket 802 and the second adjusting bracket 803 can be effectively limited, preventing the bracket from slipping out of the slide groove due to excessive sliding. At the same time, the locking block can support the sliding fixing plate 806 at a specific position, which enhances the structural rigidity of the cable when it is bent, avoids excessive deformation of the mounting protective seat 3 when it is under force, and ensures the protective strength of the bent part.

[0022] Please see Figure 2-4A further solution based on this embodiment is as follows: the fixing component includes a return spring 808 and an elastic pad 807 disposed between the annular sleeve 2 and the mounting protective seat 3, a slot 804 opened inside the mounting protective seat 3, a limiting soft frame 805 fixedly connected to one end of the mounting protective seat 3, and the limiting soft frame 805 snapping into the inside of the slot 804. The connection between the mounting protective seats 3 and the mounting protective seat 3 is achieved by the limiting soft frame 805 snapping into the inside of the slot 804. Through the buffering effect of the return spring 808 and the elastic pad 807, the hard collision of the mounting protective seat 3 during sliding and rotation can be reduced, protecting the integrity of the components. At the same time, the snapping structure of the limiting soft frame 805 and the slot 804 can quickly achieve a stable connection between adjacent mounting protective seats 3, which not only ensures the continuity of the overall protection, but also facilitates installation and subsequent maintenance. The elastic design can also adapt to a certain degree of deformation, improving the impact resistance of the structure.

[0023] Please see Figure 2-4 A further solution based on this embodiment is as follows: a protrusion is provided on the limiting soft frame 805, and a slot is provided on the slot 804 at the position of the protrusion. The protrusion is engaged inside the slot of the slot 804. By providing a protrusion on the limiting soft frame 805 and cooperating with the slot of the slot 804, the connection tightness between adjacent mounting protective seats 3 is further enhanced, preventing the mounting protective seats 3 from loosening and detaching when the cable shakes or is subjected to force. The interlocking structure of the protrusion and the slot can distribute the force on the connection part, reduce the wear of a single contact point, ensure that the connection structure can remain stable in long-term use, and improve the overall reliability of the protective shell.

[0024] Please see Figure 5 A further solution based on this embodiment is as follows: the protective component includes a fixed bracket 907 fixedly connected to the outside of the cable body 4, a ceramic fiber 908 disposed inside the fixed bracket 907, a high-temperature resistant layer 906 fixedly connected to the fixed bracket 907, an elastic bead 905 disposed on the high-temperature resistant layer 906, a heat-conducting layer 904 disposed on the elastic bead 905, a heat-dissipating layer 903 disposed on the heat-conducting layer 904, a protective steel wire 902 disposed outside the heat-dissipating layer 903, and an outer protective layer 901 disposed between the protective steel wire 902 and the cable jacket 1. The frame 907 provides stable support for the cable body 4, and the inner ceramic fiber 908 can improve the high temperature resistance of the cable. The high temperature resistant layer 906 further enhances the thermal protection capability. The elastic bead 905 can buffer external impacts and reduce damage to the internal structure. The combination of the heat-conducting layer 904 and the heat dissipation layer 903 can quickly dissipate the heat generated during cable operation and avoid high temperature accumulation. The protective steel wire 902 enhances the tensile and puncture resistance of the overall structure. The outer protective layer 901 provides additional protection for the cable jacket 1. The synergistic effect of multiple structures greatly improves the comprehensive protection performance of the cable.

[0025] Please see Figure 5 A further solution based on this embodiment is as follows: a plurality of elastic beads 905 are provided, and the plurality of elastic beads 905 are evenly disposed between the high temperature resistant layer 906 and the heat-conducting layer 904. By evenly distributing the plurality of elastic beads 905 between the high temperature resistant layer 906 and the heat-conducting layer 904, the buffering force can be evenly distributed in the circumferential direction, ensuring that when the cable is subjected to an external force impact from any direction, the impact force can be effectively absorbed by the deformation of the elastic beads 905, avoiding structural damage caused by excessive local stress.

[0026] Working principle: When the cable sheath 1 needs to be folded, pull the adjacent protective mounting seat 3, causing the annular sleeve 2 to slide along the cable sheath 1, exposing the hidden first adjusting bracket 802 and second adjusting bracket 803. Utilizing their rotational connection characteristics, the protective seat can rotate at multiple angles to meet bending requirements. The sliding groove of the protective mounting seat 3 provides guidance for the bracket and sliding fixing plate 806, and the locking block limits the sliding range to prevent detachment. In the fixing assembly, the limiting soft frame 805 and the slot 804 securely engage the protective seat, and the return spring 808 and elastic soft pad 807 buffer collisions. In the internal protective assembly, the fixing bracket 907 supports the cable body 4, the ceramic fiber 908 and the high-temperature resistant layer 906 resist high temperatures, the elastic bead 905 buffers impacts, the heat-conducting layer 904 and the heat dissipation layer 903 dissipate heat, and the protective steel wire 902 and the outer protective layer 901 enhance physical protection, achieving both adaptation and protection effects.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
