Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a protective device for cable construction in power distribution engineering. Background Technology

[0002] Cables in power distribution engineering are crucial carriers for transmitting and distributing electrical energy, playing a key role in connecting various electrical devices and transmitting power within power distribution systems. Protective devices are necessary during construction because the complex construction environment makes cables susceptible to mechanical damage, moisture, and corrosion, affecting their performance and lifespan. Protective devices are specifically designed to protect cables during construction. Their functions include preventing damage from scratches and impacts, preventing moisture intrusion that could degrade insulation, and resisting the corrosive effects of chemicals, thereby ensuring smooth cable construction and guaranteeing the stability and safety of power transmission.

[0003] Cable protection devices in power distribution projects typically consist of cable protection pipes, cable trays, cable trench covers, insulating materials, and warning signs. Cable protection pipes protect cables from external pressure and abrasion; cable trays provide support and a laying path for cables, facilitating cable management and maintenance; cable trench covers cover the trenches to prevent personnel and objects from falling in and damaging the cables; insulating materials such as insulating tape and insulating coatings enhance the insulation performance of the cables and prevent leakage accidents; warning signs serve as reminders to avoid accidental damage to the cables during construction.

[0004] In existing technologies, some cable construction protection devices in power distribution projects cannot be disassembled, making it impossible to quickly inspect their internal condition. When cable faults or potential hazards occur, maintenance personnel find it difficult to quickly locate the root cause of the problem, greatly increasing the time cost of troubleshooting, delaying power repairs, affecting power supply stability, and causing inconvenience to users. Therefore, a cable construction protection device for power distribution projects is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cable construction protection device for power distribution projects. It aims to improve the existing technology, which makes it difficult for maintenance personnel to quickly locate the root cause of problems when cables malfunction or have potential hazards. This greatly increases the time cost of troubleshooting, delays power repair, affects power supply stability, and causes inconvenience to users.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A protective device for cable construction in power distribution engineering includes an upper shell, with a cover fixedly connected to both the front and rear sides of the upper shell.

A moving block two is rotatably connected to the right side of the rotating plate. A limit rod is slidably connected inside the moving block two. A force-applying ring is fixedly connected to the outside of the limit rod. A spring two is fixedly connected to the rear side of the force-applying ring. A force-applying rod is fixedly connected to the bottom of the cover. A buffer assembly for buffering cables is fixedly connected to the inner wall of the upper shell.

[0009] The buffer assembly includes a fixed plate, the top of which is fixedly connected to the inner wall of the upper shell, a fixed rod is fixedly connected to the bottom of the fixed plate, a force-bearing ring is fixedly connected to the bottom of the fixed rod, a movable shell is slidably connected to the outside of the fixed rod, a semi-circular ring is fixedly connected to the bottom of the movable shell, and a spring is fixedly connected to the bottom of the force-bearing ring.

[0010] As a further description of the above technical solution:

[0011] The outer side of the force-applying ring is slidably connected to the inner wall of the second movable block, the rear side of the second spring is fixedly connected to the rear inner wall of the second movable block, and the rear side of the protective shell is fixedly connected to the lower shell.

In addition, it can effectively reduce the risk of damage to the cable from external impacts, avoid damage to the internal structure of the cable caused by impacts, and thus ensure stable power transmission of the cable.

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.

[0033] Reference Figures 2 to 4 This utility model provides an embodiment of a cable construction protection device for power distribution projects, comprising an upper shell 1, which protects the equipment. Upper covers 3 are fixedly connected to both the front and rear sides of the upper shell 1. A protective shell 4 is fixedly connected to the bottom of the upper covers 3. The upper covers 3 and the protective shell 4 provide protection and thus fix the protective device. Moving rods 5 are slidably connected to the left and right sides of the protective shell 4. The moving rods 5 receive external force and move accordingly. A moving block 8 is rotatably connected to the right side of the moving rod 5. The moving block 8 receives external force from the moving rod 5 and moves accordingly. A rotating plate 9 is rotatably connected to the right side of the moving block 8. A moving block is rotatably connected to the right side of the rotating plate 9. The rotating plate 9 receives the force from the moving block 8, causing it to rotate, which in turn drives the moving block 10 to move. The moving block 10 has a sliding connection to a limit rod 13 inside. A force ring 12 is fixedly connected to the outside of the limit rod 13. A spring 11 is fixedly connected to the rear side of the force ring 12. A force rod 14 is fixedly connected to the bottom of the top cover 3. The limit rod 13 limits the force rod 14. The spring 11 applies force to the limit rod 13 and receives the moving force of the limit rod 13. The force ring 12 moves with the limit rod 13, causing the spring 11 to be compressed. A buffer assembly for buffering cables is fixedly connected to the inner wall of the upper shell 1.

[0034] Reference Figure 2 and Figure 5The buffer assembly includes a fixed plate 15, the top of which is fixedly connected to the inner wall of the upper shell 1, a fixed rod 16 is fixedly connected to the bottom of the fixed plate 15, a force-receiving ring 17 is fixedly connected to the bottom of the fixed rod 16, a movable shell 20 is slidably connected to the outside of the fixed rod 16, a semi-circular ring 19 is fixedly connected to the bottom of the movable shell 20, and a spring 18 is fixedly connected to the bottom of the force-receiving ring 17. The fixed plate 15 is fixed to the inner wall of the upper shell 1 to stabilize it. The fixed rod 16 receives the force transmitted by the force-receiving ring 17 to stabilize it. The movable shell 20 receives the force applied by the semi-circular ring 19 to move, thereby compressing the spring 18.

[0035] Reference Figures 1 to 3 The force-applying ring 12 is externally slidably connected to the inner wall of the moving block 10. The force-applying ring 12 receives the pushing force of the limiting rod 13, thereby moving. The rear side of the spring 11 is fixedly connected to the rear inner wall of the moving block 10. The spring 11 receives the pushing force of the force-applying ring 12, thereby storing elastic force. The rear side of the protective shell 4 is fixedly connected to the lower shell 2, which contacts the upper shell 1 and protects its wires. The front side of the limiting rod 13 is slidably connected to the rear side of the force-applying rod 14. The limiting rod 13 is a force-applying rod. Rod 14 is limited to ensure stability. The external part of the force-applying rod 14 is slidably connected to the inner wall of the protective shell 4. The force-applying rod 14 receives external force and thus moves within the protective shell 4. A fixing plate 23 is fixedly connected to the left side of the moving rod 5. The fixing plate 23 receives external force and thus drives the moving rod 5 to move. A limiting plate 6 is fixedly connected to the outside of the moving rod 5. The outside of the limiting plate 6 is slidably connected to the inner wall of the upper cover 3. The limiting plate 6 limits the moving rod 5, preventing it from moving. The rotating plate 9 is externally rotatably connected to the inner wall of the protective shell 4. The rotating plate 9 receives the pushing force of the moving rod 5, thereby rotating. A spring 7 is fixedly connected to the right side of the limiting plate 6. The spring 7 receives the force transmitted by the limiting plate 6, thereby storing elastic force. A cable 24 is fixedly connected to the bottom of the semi-circular ring 19. The cable 24 is an electrical cable. A sealing ring 21 is fixedly connected to the outside of the cable 24. The sealing ring 21 is externally fixedly connected to the inner wall of the upper shell 1. The sealing ring 21 protects the protective device. The sealing ring 21 is sealed and stable inside. The top of the sealing ring 21 is fixedly connected to the limiting plate 22. The outside of the limiting plate 22 is fixedly connected to the inner wall of the upper shell 1. The limiting plate 22 protects the sealing ring 21 and makes it stable. The bottom of the spring 3 18 is fixedly connected to the bottom inner wall of the movable shell 20. The top of the force ring 17 is fixedly connected to the top inner wall of the movable shell 20. The spring 3 18 receives the force applied by the movable shell 20, thereby storing the elastic force. The force ring 17 receives the elastic force of the spring, so that the spring stores the elastic force here.

[0036] Working principle: The operator rotates the moving rod 5, causing its limiting plate to rotate. At this time, the internal slot facilitates the movement of the limiting plate. Spring 7 releases its elastic force, thereby driving the moving rod 5 to move, which in turn causes the rotating plate 9 to rotate, thereby driving the moving block 10 to move. This causes the limiting rod 13 to drive the force-applying rod 14 to move. After the limiting rod 13 has moved for a certain period of time, it is locked into the limiting groove under the action of spring 11, thereby disengaging the limiting rod 13 from the force-applying rod 14. This allows the protective shell 4 to detach from the top cover 3, thus achieving rapid disassembly of the protective device. In addition, it reduces project delays caused by the time spent on device disassembly, making the cable construction process more compact and smooth.

[0037] When the cable is impacted, the semicircular ring 19 moves, which in turn moves the movable shell 20. The movable shell 20 then compresses the internal spring, causing the spring to be cushioned by the force, and thus the semicircular ring 19 is also cushioned. This provides buffer protection for the cable and effectively reduces the risk of damage to the cable from external impacts, preventing damage to the internal structure of the cable due to impacts, thereby ensuring stable power transmission of the cable.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
