[0034] The present invention will be further described in detail below with reference to embodiments:

[0035] Example 1

[0036] Please see Figures 1-11 This embodiment provides a cable protection device for power engineering, including a cable threading assembly 1, a combined frame 2, two hooks 3, and a cable 5. The two hooks 3 are rotatably connected within the combined frame 2, and the combined frame 2 is slidably connected within the cable threading assembly 1. A sliding groove 142 in the cable threading assembly 1 restricts the movement direction of the combined frame 2, allowing it to slide only up and down within the cable threading assembly 1. The cable 5 is slidably connected to the cable threading assembly 1. The water-conducting shell 10 and the cable threading tube 12 in the cable threading assembly 1 can be of any length in actual use. Other components can be evenly distributed outside the water-conducting shell 10 or distributed as needed.

[0037] The cable threading assembly 1 includes a water guide shell 10, a water guide cavity 11, a cable threading tube 12, four springs 13, and a mechanical compartment 14. The cable threading assembly 1 is primarily made of highly corrosion-resistant polytetrafluoroethylene (PTFE), which is lighter than metal materials and possesses extremely high high-temperature resistance, with a long-term operating temperature range of -200℃ to +260℃, maintaining stability even under extreme temperatures. Compared to the cable threading assembly 1, the remaining structures typically use titanium alloy, a high-strength, corrosion-resistant metallic material widely used in marine engineering construction. It can withstand harsh environments such as seawater, air, and waves, exhibiting superior corrosion resistance and high strength.

[0038] Four springs 13 are fixedly connected at one end to the outside of the conduit 12 and at the other end to the inside of the water-conducting shell 10. The four-way springs 13, due to their characteristics, prevent the conduit 12 from shifting due to falling or impact, increasing the stability of the cable 5 during installation. The water-conducting cavity 11 is fixedly connected to the water-conducting shell 10, and the mechanical chamber 14 is fixedly connected to the water-conducting cavity 11. The water-conducting shell 10 is typically designed as an elliptical structure, allowing river water to flow along its outer wall without impacting it; while the water-conducting cavity 11 effectively reduces the impact of water flow on other parts, further improving the lifespan of the cable protection device.

[0039] The mechanical compartment 14 has a movable cavity 140 and two limiting cavities 141, which are located on both sides of the movable cavity 140. The main function of the limiting cavities 141 is to work together with the limiting block 31 to reinforce and limit the position of the hook 3, prevent the hook 3 from swaying laterally, and make it more stable.

[0040] The hook 3 includes a claw 30, four limiting blocks 31, and two levers 32. One end of the claw 30 is fixedly connected to the four limiting blocks 31 and the two levers 32. The four limiting blocks are disposed within the limiting cavity 141, and the two levers 32 are disposed within the moving cavity 140. The claw 30 can also be hemispherical in shape. This shape is mainly suitable for situations where there are few rocks on the seabed. If there are many rocks or other debris on the seabed where the cable 5 is laid, an open-type claw 30 should be used.

[0041] The moving cavity 140 and the two limiting cavities 141 are each provided with a sliding groove 142; the sliding groove 142 allows the push rod 21 to move upward along the direction of the set sliding groove 142 without deviating.

[0042] Combination Figure 9 The combined frame 2 includes: a base plate 20, a push rod 21, two limiting shafts 22, and two fixed shafts 23. The base plate 20 is square in shape, with three square holes of the same size as the moving cavity 140 and the two limiting cavities 141. Holes penetrating the three square holes are formed inside the square holes in the base plate 20 for mounting the rotating shaft connecting the hook 3. The rotating shaft typically uses a telescopic rod with telescopic functions at both ends, with cylinders of the same diameter as the holes fixedly connected to the relatively distant ends to prevent the rotating shaft from wobbling. The telescopic rod is a retractable mechanical structure composed of multiple interlocking cylinders, each with internal and external threads at both ends, achieving both telescopic extension and length fixation. High-strength and high-toughness materials are required.

[0043] One end of the push rod 21 is fixedly connected to the base plate 20, and the other end is fixedly connected to two limiting shafts 22, which are slidably connected to the sliding groove 142. The end of the limiting shaft 22 away from the push rod 21 can also use a telescopic rod structure. One end of the push rod 21 has a concave groove, and two fixed shafts 23 are fixedly connected in the concave groove. The two fixed shafts 23 are symmetrical with respect to the central axis of the combined frame 2 in one direction and are a certain distance away from the bottom of the concave groove, so that the rotating rod 40 can rotate smoothly along the fixed shafts 23.

[0044] The cable protection device for power engineering also includes two connecting rods 4, which are rotatably connected to two fixed shafts 23. When the combined frame 2 moves upward, it drives the end of the connecting rod 4 connected to the fixed shaft 23 to rotate and move upward simultaneously. The connecting rod 4 includes a rotating rod 40 and a moving rod 41. One end of the moving rod 41 is rotatably connected to the rotating rod 40, and the other end has a hook groove 410, which abuts against the lever 32. Because the limiting groove 143 is a horizontal groove, the moving rod 41 can only move laterally along the limiting groove 143. Further changing the angle of the rotating rod 40 causes the end rotatably connected to the moving rod 41 to also move with the moving rod 41, thereby changing the lateral distance of the connecting rod 4. This causes the lever 32 to shift outward, closing the two claws 30 at the other end.

[0045] The connecting rod 4 also includes a limiting hook 42; four limiting grooves 143 are provided on the two inner walls of the moving cavity 140, the limiting grooves 143 are in a "Z" shape, and the limiting hook 42 is rotatably connected in the limiting groove 143; the limiting hook 42 includes: a hook body 420 and a rebound spring 421, one end of the rebound spring 421 is fixedly connected in the limiting groove 143, and the other end is fixedly connected to the hook body 420. When one end of the hook groove 410 of the moving rod 41 moves to contact the limiting hook 42, it will squeeze the limiting hook 42, causing it to rotate upward a certain distance. When the moving rod 41 continues to move, the hook body 420 will return to its initial position under the action of the rebound spring 421, thereby making the hook body 420 engage with the hook groove 410, further preventing the moving rod 41 from moving in the opposite direction, thus achieving the limiting function.

[0046] The working principle of this type of cable protection device for power engineering will be explained in detail below.

[0047] like Figure 1-11As shown, in use, cable 5 is threaded through conduit 12, and then cable 5 is placed in water to sink naturally. Due to the water guide shell 10 and water guide cavity 11, the impact of water flow on the device during descent is greatly reduced, protecting cable 5 from being coiled or twisted by the water flow. When the protective device reaches the bottom, spring 13 in the threading assembly 1 reduces the vibration of cable 5 caused by the impact. Due to inertia, the threading assembly 1 continues to move downward, causing the combined frame 2 and hook 3 to move upward relative to the threading assembly 1. This further causes the moving rod 41 to move laterally along the limiting groove 143, and then changes the angle of the rotating rod 40, making... The end rotatably connected to the moving rod 41 also moves with the moving rod 41. At the same time, when the moving rod 41 continues to move, the hook body 420 will return to its initial position under the action of the rebound spring 421, so that the hook body 420 engages with the hook groove 410, further preventing the moving rod 41 from moving in the opposite direction, thereby achieving the function of limiting. The change in the lateral distance of the connecting rod 4 will cause the lever 32 to shift outward, causing the two claws 30 at the other end to close, so that the two claws 30 can grab stones or mud and sand, thereby achieving the function of fixing itself, further preventing the cable 5 from directly contacting the bottom of the water, avoiding the wear and corrosion of the cable 5 by the mud and sand at the bottom of the water, and extending the service life of the cable 5.

[0048] When it is necessary to change the type of hook 3, simply rotate the two ends of the telescopic rod connecting the hook 3 and the combined frame 2 in opposite directions. This will cause the telescopic rod to shorten inward. When it reaches the shortest position, the hook 3 along with the telescopic rod can be removed. Then, the new type of hook 3 can be connected to the combined frame 2 through the telescopic rod.

[0049] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
