Description

Technical Field

[0001] This application relates to the field of cable protection technology, and in particular to a cable protection device for power engineering. Background Technology

[0002] Traditional cable protection devices for power engineering often employ simple sheath structures, resulting in significant gaps between the protective sheath and the cable, making it difficult to prevent the intrusion of dust, moisture, and corrosive substances. Furthermore, the fixed protective structure is ill-suited to the protection needs of cables of different specifications and installed environments. For cables at bends, corners, or in environments requiring frequent movement or vibration, traditional devices fail to provide adequate protection, leading to cable sheath wear and internal core breakage, impacting the stability and reliability of power transmission. Moreover, traditional cable connectors lack effective guiding structures when mating with equipment or other cables, making insertion errors likely.

[0003] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0004] To address the problems of traditional power engineering cable protection devices, which often employ simple sleeve structures with large gaps between the protective sleeve and the cable, making it difficult to prevent the intrusion of dust, moisture, and corrosive substances, and whose fixed protective structures are ill-suited to the protection needs of cables of different specifications and in different installation environments, this application provides a power engineering cable protection device.

[0005] The power engineering cable protection device provided in this application adopts the following technical solution:

[0006] A cable protection device for power engineering includes a protective tube, a fixing sleeve fixed in the middle of the outer wall of the protective tube, and matching protective covers movably installed on both ends of the protective tube. Connectors are connected to both ends of the protective tube, and sliding sleeves are fixed on the outer walls of the connectors. A set of balls are evenly distributed along the circumference of the outer wall of the sliding sleeves.

[0007] Preferably, both ends of the fixing sleeve are provided with connecting cavities, and a return spring for supporting the protective cover is connected inside the connecting cavity.

[0008] Preferably, the ends of the two protective covers that are close to each other are connected to threaded connecting pipes that are adapted to the threads of the connecting cavity.

[0009] Preferably, the threaded connecting pipe has a circular hole inside that is adapted to the protective pipe, and the circular hole communicates with the protective cover.

[0010] Preferably, the inner walls of the two protective covers at their opposite ends are sealed with sealing rubber rings, and the sliding sleeve is tapered.

[0011] Preferably, the outer wall of the sliding sleeve is provided with a set of movable holes that are adapted to the balls at equal intervals along the circumference, and the interior of the sliding sleeve is provided with an installation port that communicates with the protective tube.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] This application achieves automatic initial protection and flexible positioning of the protective cover through the combination of a return spring and a threaded connection structure. This simplifies the operation process, adapts to complex and diverse installation scenarios, and significantly improves installation efficiency. The sealing protection system constructed by the sealing rubber ring can completely isolate harmful external factors, effectively delay cable aging, and reduce the risk of power failure and maintenance costs. The tapered sleeve and ball bearing design at the connector not only provides precise guidance and reduces docking errors, but also significantly reduces friction due to the rolling of the balls, making complex connection work easy and efficient. At the same time, the stable connection structure ensures stable and safe power transmission, effectively avoiding power outages caused by loose connections. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a cable protection device for power engineering. (Refer to...) Figure 1The system includes a protective tube 1, with a fixing sleeve 2 fixed to the middle of its outer wall. Adaptive protective covers 5 are movably installed at both ends of the protective tube 1. Each end of the fixing sleeve 2 has a connecting cavity 3, and a return spring 4 supporting the protective cover 5 is connected inside the connecting cavity 3. The elasticity of the return spring 4 automatically pushes the protective cover 5 away, quickly providing initial protection to both ends of the protective tube 1 after the cable is passed through, eliminating the need for cumbersome manual adjustment. Furthermore, the connecting cavity 3 between the protective cover 5 and the fixing sleeve 2 uses a threaded connecting tube 12 for threaded adaptation; simply rotating the protective cover 5 easily completes the positioning. This installation method is not only simple to operate but also allows for flexible adjustment of the distance between the protective cover 5 and the protective tube 1 according to actual needs, adapting to different installation scenarios and cable layout requirements, greatly improving installation efficiency and flexibility.

[0020] Reference Figure 2 Each of the two protective covers 5 has a threaded connecting tube 12 at its closest end, which is compatible with the thread of the connecting cavity 3. The threaded connecting tube 12 has a circular hole inside that is compatible with the protective tube 1 and communicates with the protective cover 5. The inner walls of the two protective covers 5 at their furthest ends are sealed with sealing rubber rings 6. After installation, the sealing rubber rings 6 on the inner walls of the protective covers 5 tightly fit the cable, forming an effective sealing barrier. This effectively prevents external dust, moisture, corrosive substances, etc., from entering the protective tube 1, avoiding problems such as aging and short circuits caused by cable corrosion.

[0021] Combination Figure 3 As shown, the protective tube 1 is connected to two ends with connectors 7. The outer wall of the connector 7 is fixed with a sliding sleeve 8. The sliding sleeve 8 is tapered. The tapered design of the sliding sleeve 8 on the outer wall of the connector 7 can play a precise guiding role when docking with other equipment or cable interfaces, so that the connector 7 can be easily and accurately inserted into the interface, reducing deviations and errors in the docking process.

[0022] In this application, a set of balls 10 are evenly distributed circumferentially on the outer wall of the sliding sleeve 8, and a set of movable holes 9 adapted to the balls 10 are equally distributed circumferentially on the outer wall of the sliding sleeve 8. An installation port 11 communicating with the protective tube 1 is provided inside the sliding sleeve 8. The balls 10 can roll flexibly within the movable holes 9, which not only significantly reduces the frictional resistance between the sliding sleeve 8 and the inner wall of the interface, but also further reduces the friction on the cable during insertion by contacting the cable, making the insertion process of the connector 7 smoother and greatly reducing the installation difficulty. Even complex connection operations can be easily completed by the operator.

[0023] The implementation principle of a power engineering cable protection device according to an embodiment of this application is as follows:

[0024] During installation, the cable is first passed through the protective tube 1. The elasticity of the return spring 4 pushes the two protective covers 5 away, thus protecting both ends of the protective tube 1. The protective covers 5 can also be threadedly connected to the connecting cavity 3 of the fixing sleeve 2 via the threaded connecting tube 12. During installation, the protective cover 5 is rotated, causing the threaded connecting tube 12 to screw into the connecting cavity 3. As the threads engage, the protective cover 5 is positioned, allowing for easy adjustment of the protection distance according to actual needs. At this time, the return spring 4 is compressed, accumulating elastic potential energy. Once the protective cover 5 is in place, its inner sealing rubber ring 6 tightly adheres to the cable, forming a sealed structure that effectively prevents external dust, moisture, corrosive substances, etc., from entering the protective tube 1, preventing cable corrosion and extending cable lifespan.

[0025] When connecting cables to other devices or cables, align connector 7 with the interface. Due to the tapered design of the sliding sleeve 8, it acts as a guide during the docking process, making it easier to insert connector 7 into the interface. At the same time, the ball bearing 10 can roll flexibly within the movable hole 9 and contact the cable, greatly reducing the frictional resistance between the sliding sleeve 8 and the inner wall of the interface and the cable, allowing connector 7 to be inserted more smoothly and reducing installation difficulty.

[0026] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
