Description

Technical Field

[0001] This utility model relates to the field of insulated power cable technology, and more specifically, to an insulated power cable. Background Technology

[0002] In the field of power cables, ensuring the insulation performance of cables is crucial, especially at cable joints. Existing insulated power cables have some problems with the protection of joints, which may affect the overall performance and safety of the cable.

[0003] Firstly, traditional insulated power cables typically use insulating sleeves to wrap the cable. This method provides good insulation protection for the cable body. However, when two cables need to be joined, this method of wrapping the insulating sleeves reveals its limitations. The insulating sleeves at the joint are often more susceptible to external forces, such as bending, stretching, or impact, which can lead to damage. This damage may cause a decrease in the insulation performance of the cable, or even short circuits or leakage, threatening the stable operation of the power system.

[0004] Secondly, in order to solve the problem of joint protection, existing technologies have introduced a method of covering the outside of the joint with a protective sleeve. This design aims to enhance the insulation performance and mechanical strength of the joint by adding a layer of protection. However, the installation and removal of this protective sleeve is often cumbersome and requires professional tools and skills. This not only increases the difficulty of maintenance but also prolongs the maintenance time and reduces the flexibility and rapid response capability of the power system.

[0005] In addition, some power cable installations use special structures to achieve quick installation of protective sleeves to simplify the maintenance process. However, these structures are often too simple, resulting in low installation stability. During the operation of the power system, the position of the protective sleeve may become loose due to external forces, which may affect the insulation performance of the joint. This loosening may lead to cable failure or even serious accidents such as fire. Utility Model Content

[0031] Please see Figure 1-5 An insulated power cable 1 includes a cable 1, characterized in that: a protective device is installed on the outside of the cable 1, and an installation device is provided on the outside of the cable 1. The installation device includes a rotating sleeve 2, a mating sleeve 3, a clamping block 4, a sliding sleeve 5, an adapter 6, a sliding groove 7, a threaded groove 8, and a sliding block 9. The two ends of the rotating sleeve 2 are movably connected to the mating sleeve 3 and the adapter 6, respectively. One side of the clamping block 4 is slidably installed in the sliding groove 7. The sliding sleeve 5 is movably disposed inside the rotating sleeve 2. The sliding groove 7 is formed in the mating sleeve 3, and the threaded groove 8 is formed in the rotating sleeve 2. Inside, the sliding block 9 is slidably disposed in the threaded groove 8, and the sliding block 9 is fixedly disposed on the outside of the sliding sleeve 5. A protective mechanism is provided on the outside of the mating sleeve 3. The protective mechanism includes a limiting sleeve 10, a conical spring 11, a positioning rod 12 and a positioning groove 13. The two limiting sleeves 10 are respectively movably installed on the outside of the mating sleeve 3 and the adapter sleeve 6 by threads. One end of the positioning rod 12 is connected to the outside of the rotating sleeve 2 through the conical spring 11, and the other end of the positioning rod 12 is inserted into the positioning groove 13. Multiple positioning grooves 13 are respectively opened on the outside of the mating sleeve 3 and the adapter sleeve 6.

[0032] The inner side of the fitting sleeve 3 is provided with a fixing plate 14, and a push spring 15 is provided on one side of the fixing plate 14. The other end of the push spring 15 is connected to the clamping block 4.

[0033] The sliding groove 7 is designed with an inclined structure.

[0034] The inner side of the fitting 6 is provided with a slider 16, and the outer side of the sliding sleeve 5 is provided with a corresponding groove 17, which is adapted to the slider 16.

[0035] A rubber plate 18 is provided on one side of the clamping block 4, and the rubber plate 18 can be detachably installed on one side of the clamping block 4.

[0036] The rotating sleeve 2 and the limiting sleeve 10 are provided with anti-slip strips 19 on their outer sides, and multiple anti-slip strips 19 are fixedly connected to the outer sides of the rotating sleeve 2 and the limiting sleeve 10.

[0037] In this embodiment, when the device is needed, firstly, the two limiting sleeves 10 are rotated, and then the limiting sleeves 10 will move spirally along the thread direction. Then, the outer side of the positioning rod 12 will lose the limiting of the inner wall of the limiting sleeve 10. Then, the rotating sleeve 2 is rotated, and the rotating sleeve 2 will drive the positioning rod 12 to move. Then, the side wall of the positioning groove 13 will squeeze the side wall of the positioning rod 12. Due to the rounded corner structure design of the side wall of the positioning groove 13 and one end of the positioning rod 12, and the fact that the conical spring 11 only provides a weak reset function, one end of the positioning rod 12 will then exit from the positioning groove 13. The sliding sleeve 5 slides out, and then the other end of the positioning rod 12 will drive the conical spring 11 to stretch. At the same time, the rotating sleeve 2 will drive the inner threaded groove 8 to rotate. Since the sliding block 9 is slidably set in the threaded groove 8, and the slider 16 and the groove 17 set on the inner side of the matching sleeve 6 cooperate to limit the sliding sleeve 5, then the sliding block 9 set on the outer side of the sliding sleeve 5 will slide along the threaded groove 8, and at the same time the sliding sleeve 5 will slide along the slider 16 and the groove 17. Then, one side of the clamping block 4 will lose the limitation of the sliding sleeve 5, and then the push spring 15 connected to one side of the fixing plate 14 will reset and push. The clamping block 4 slides along the sliding groove 7. Due to the inclined structure design of the sliding groove 7, the clamping block 4 expands outward while sliding, and then the mating sleeves 3 are respectively fitted onto the outer side of the corresponding cable 1. Then the spring 21 is fitted onto the outer side of the cable 1, and then the two cables 1 are joined together. Then the mating sleeves 3 are moved to the corresponding positions, so that the two mating sleeves 3 compress the spring 21 through the push plate. Then the rotating sleeve 2 is rotated in the opposite direction. The rotating sleeve 2 drives the sliding sleeve 5 to reset along the slider 16 and the sliding groove 17 through the cooperation of the threaded groove 8 and the sliding block 9. The rear sliding sleeve 5 pushes the clamping block 4 to reset along the sliding groove 7. Then, the clamping block 4 cooperates with the fixing plate 14 to squeeze the push spring 15. Then, the clamping block 4 presses the insulating sleeve 20 through the rubber plate 18 on one side. Then, the limiting sleeve 10 is rotated in the opposite direction, so that the limiting sleeve 10 resets along the thread. Then, the inner wall of the limiting sleeve 10 limits the outer side of the positioning rod 12 again, thereby preventing the positioning rod 12 from moving. Then, the positioning rod 12 and the positioning groove 13 cooperate to effectively prevent the rotating sleeve 2 from moving, thus realizing the rapid and stable installation of the protective structure.

[0038] Please see Figure 1-2As one implementation of the protection device: the protection device includes an insulating sleeve 20, a spring 21 and a clamping plate 22. The insulating sleeve 20 is detachably sleeved on the outside of the cable 1, the clamping plate 22 is fixedly connected to both ends of the spring 21, and the spring 21 is movably sleeved on the outside of the insulating sleeve 20.

[0039] The outer side of the insulating sleeve 20 is provided with rubber rings 23, and multiple rubber rings 23 are fixedly connected to the outer side of the insulating sleeve 20.

[0040] More specifically, the insulating sleeve 20 isolates the outside of the cable 1, achieving external insulation protection for the cable 1. The rubber ring 23 increases the friction on the outside of the insulating sleeve 20, making the installation more stable. The spring 21 and push plate improve the structure of the traditional protective sleeve, allowing the connection to be bent, making it more convenient and flexible to use. When protecting different cables 1, only the spring 21 of different specifications needs to be replaced.

[0041] In summary, during the use or operation of the overall equipment: When the equipment needs to be used, first rotate the two limiting sleeves 10. Then, the limiting sleeves 10 will move spirally along the thread direction. Then, the outer side of the positioning rod 12 will lose the limiting of the inner wall of the limiting sleeve 10. Then, rotate the rotating sleeve 2, which will drive the positioning rod 12 to move. Then, the side wall of the positioning groove 13 will squeeze the side wall of the positioning rod 12. Due to the rounded corner structure design of the side wall of the positioning groove 13 and one end of the positioning rod 12, and the fact that the conical spring 11 only provides a weak reset function, one end of the positioning rod 12... The sliding sleeve 5 will slide out of the positioning groove 13, and then the other end of the positioning rod 12 will drive the conical spring 11 to stretch. At the same time, the rotating sleeve 2 will drive the inner threaded groove 8 to rotate. Since the sliding block 9 is slidably set in the threaded groove 8, and the slider 16 and the slide groove 17 set on the inner side of the matching sleeve 6 cooperate to limit the sliding sleeve 5, then the sliding block 9 set on the outer side of the sliding sleeve 5 will slide along the threaded groove 8, and at the same time the sliding sleeve 5 will slide along the slider 16 and the slide groove 17. Then the clamping block 4 will lose the limit of the sliding sleeve 5, and then the push spring 15 connected to the side of the fixing plate 14 will... The reset pusher 4 slides along the sliding groove 7. Due to the inclined structure design of the sliding groove 7, the clamp 4 will spread outward while sliding, and then the mating sleeves 3 are respectively fitted onto the outside of the corresponding cables 1. Then the spring 21 is fitted onto the outside of the cable 1, and then the two cables 1 are joined together. Then the mating sleeves 3 are moved to the corresponding positions, so that the two mating sleeves 3 compress the spring 21 through the push plate. Then the rotating sleeve 2 is rotated in the opposite direction. The rotating sleeve 2 drives the sliding sleeve 5 to reset along the slider 16 and the sliding groove 17 through the cooperation of the threaded groove 8 and the sliding block 9. Then, the sliding sleeve 5 pushes the clamping block 4 to reset along the sliding groove 7. Then, the clamping block 4 cooperates with the fixing plate 14 to squeeze the push spring 15. Then, the clamping block 4 presses the insulating sleeve 20 through the rubber plate 18 set on one side. Then, the limiting sleeve 10 is rotated in the opposite direction, so that the limiting sleeve 10 resets along the thread. Then, the inner wall of the limiting sleeve 10 limits the outer side of the positioning rod 12 again, thereby preventing the positioning rod 12 from moving. Then, the positioning rod 12 and the positioning groove 13 cooperate to effectively prevent the rotating sleeve 2 from moving, thus realizing the rapid and stable installation of the protective structure.

[0042] The insulating sleeve 20 isolates the outside of the cable 1, achieving external insulation protection for the cable 1. The rubber ring 23 increases the friction on the outside of the insulating sleeve 20, making the installation more stable. The spring 21 and push plate improve the structure of the traditional protective sleeve, allowing the connection to be bent, making it more convenient and flexible to use. When protecting different cables 1, only the spring 21 of different specifications needs to be replaced.

For all the fixed connections mentioned above, welding is preferred.
