[0014] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0015] Reference Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a power engineering cable protection device, including a first cable joint explosion-proof box 1; a second cable joint explosion-proof box 2 is installed at the bottom of the first cable joint explosion-proof box 1; both ends of the first cable joint explosion-proof box 1 are fixedly connected to hollow blocks 3; both ends of the second cable joint explosion-proof box 2 are fixedly connected to hollow blocks 4; adjustment grooves 6 are provided on both sides of the hollow blocks 3; snap-fit ​​grooves 5 are provided on both sides of the inner cavity of the hollow blocks 4; adjustment blocks 7 are slidably connected inside the adjustment grooves 6; one side of the adjustment block 7... A connecting plate 8 is fixedly connected to one side of the connecting plate 8, and a snap-fit ​​block 9 is fixedly connected to one side of the connecting plate 8. After the workers align the bottom of the first cable intermediate joint explosion-proof box 1 with the top of the second cable intermediate joint explosion-proof box 2, they then move the adjusting block 7 to drive the connecting plate 8 to insert the snap-fit ​​block 9 into the snap-fit ​​groove 5. This achieves the effect of quickly installing the first cable intermediate joint explosion-proof box 1 and the second cable intermediate joint explosion-proof box 2, making the cable protection device for power engineering more convenient to use and greatly improving work efficiency.

[0016] Reference Figure 4 As shown in this embodiment: the hollow block 3 is fixedly connected to a limiting rod 11, and a limiting hole 10 is opened on one side of the connecting plate 8. The inside of the limiting hole 10 is slidably connected to the surface of the limiting rod 11. The cooperation between the limiting hole 10 and the limiting rod 11 makes the connecting plate 8 more stable when moving, avoiding the phenomenon of the connecting plate 8 shifting or shaking during the movement, thereby improving the stability of the power engineering cable protection device during installation.

[0017] Reference Figure 4 As shown in this embodiment: a return spring 12 is fixedly connected to one side of the connecting plate 8, and one side of the return spring 12 is fixedly connected to the inside of the hollow block 3. By setting the return spring 12, after the worker inserts the snap-fit ​​block 9 into the snap-fit ​​groove 5, the elastic force of the return spring 12 pushes the connecting plate 8 to reset, so that the snap-fit ​​block 9 can be tightly snapped into the inside of the snap-fit ​​groove 5. This further improves the stability of the first cable intermediate joint explosion-proof box 1 and the second cable intermediate joint explosion-proof box 2 during installation, avoids the phenomenon of falling off or loosening during use, and greatly improves the safety of the power engineering cable protection device during use.

[0018] Reference Figure 3 and Figure 4As shown in this embodiment: the surface of the snap-fit ​​block 9 is slidably connected to the inside of the snap-fit ​​groove 5, the outer diameter of the snap-fit ​​block 9 is adapted to the inner diameter of the snap-fit ​​groove 5, and the tight fit between the snap-fit ​​block 9 and the snap-fit ​​groove 5 effectively enhances the stability of the device during operation, prevents potential risks caused by loose connection, and greatly facilitates future disassembly and maintenance.

[0019] Reference Figure 1 As shown in this implementation scheme: the first cable joint explosion-proof box 1 and the second cable joint explosion-proof box 2 are both made of high impact-resistant insulating material. Using high impact-resistant insulating material as the main component material of the first cable joint explosion-proof box 1 and the second cable joint explosion-proof box 2 significantly improves the impact resistance and insulation performance of the device. This material can not only effectively resist the physical impact of the external environment, but also maintain a good insulation state during power transmission, greatly reducing the safety hazards caused by material problems.

[0020] Reference Figure 2 and Figure 3 As shown in this embodiment: the bottom of the first cable joint explosion-proof box 1 has two positioning grooves 13, and the top of the second cable joint explosion-proof box 2 is fixedly connected to two positioning blocks 14. The surface of the positioning blocks 14 is slidably connected to the inside of the positioning grooves 13. Through the sliding connection design between the positioning blocks 14 and the positioning grooves 13, the precise positioning and rapid assembly between the first cable joint explosion-proof box 1 and the second cable joint explosion-proof box 2 are realized. This design not only simplifies the installation process, but also improves the overall assembly accuracy and stability of the device.

[0021] Working Principle: After the operator aligns the bottom of the first cable joint explosion-proof box 1 with the top of the second cable joint explosion-proof box 2, they then move the adjusting block 7, causing the connecting plate 8 to insert the snap-fit ​​block 9 into the snap-fit ​​groove 5. This facilitates the rapid installation of the first cable joint explosion-proof box 1 and the second cable joint explosion-proof box 2, making the power cable protection device more convenient to use and greatly improving work efficiency. The cooperation of the limiting hole 10 and the limiting rod 11 ensures that the connecting plate 8 is more stable during movement, preventing deviation or shaking, thus improving the stability of the power cable protection device during installation. The return spring 12, after the operator inserts the snap-fit ​​block 9 into the snap-fit ​​groove 5, pushes the connecting plate 8 back to its original position, ensuring the snap-fit ​​block 9 is tightly engaged in the snap-fit ​​groove 5, further enhancing the connection between the first cable joint explosion-proof box 1 and the second cable joint explosion-proof box 2. The stability of the explosion-proof box 2 for the second cable intermediate joint during installation prevents it from falling off or loosening during use, greatly improving the safety of the cable protection device in power engineering. The tight fit between the snap-fit ​​block 9 and the snap-fit ​​groove 5 effectively enhances the stability of the device during operation, preventing potential risks caused by loose connections and greatly facilitating future disassembly and maintenance. High impact-resistant insulation material is used as the main component of the first and second cable intermediate joint explosion-proof boxes 1 and 2, significantly improving the impact resistance and insulation performance of the device. This material can not only effectively resist the physical impact of the external environment, but also maintain a good insulation state during power transmission, greatly reducing safety hazards caused by material problems. Through the sliding connection design of the positioning block 14 and the positioning groove 13, the precise positioning and rapid assembly between the first and second cable intermediate joint explosion-proof boxes 1 and 2 are realized. This design not only simplifies the installation process, but also improves the overall assembly accuracy and stability of the device.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
