[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0014] Please see Figures 1-3In this embodiment of the utility model, a power engineering cable protection device includes a first protective pipe 1 and a second protective pipe 2 for protecting the surface of the cable 8. A protective corrugated pipe 3 is fixedly connected between the first protective pipe 1 and the second protective pipe 2. A connecting mechanism is provided at both ends of the first protective pipe 1 and the second protective pipe 2. A limiting mechanism is installed between the outer periphery of the first protective pipe 1 and the second protective pipe 2. The ends of the first protective pipe 1 and the second protective pipe 2 that are far away from the protective corrugated pipe 3 in an adjacent state are detachably connected through the connecting mechanism. The limiting mechanism is used to keep the two parts of the connecting mechanism effectively connected.

[0015] In this embodiment: First, during the laying of cable 8, as cable 8 is laid, protective pipe 1, protective pipe 2, and protective corrugated pipe 3 are fitted around the outer periphery of cable 8 to protect the outside of cable 8. When the two protective devices are connected, the ends of the two protective devices that are close to each other are fixed using a connecting mechanism. After the fixing is completed, the limiting mechanism is connected. After the limiting mechanism is connected, the limiting mechanism limits the length of the protective corrugated pipe 3, so that it cannot be stretched or shortened at will. This can prevent the connecting mechanism from becoming loose and ensure the stability of the connecting mechanism after connection.

[0016] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The connecting mechanism includes a fixed connecting sleeve 4 fixedly installed on the end of the second protective pipe 2 away from the protective corrugated pipe 3. The fixed connecting sleeve 4 has a connecting screw hole at the end away from the second protective pipe 2. The connecting mechanism also includes a rotating connecting head 5 rotatably installed on the outer wall of the end of the first protective pipe 1 away from the protective corrugated pipe 3. The outer circumference of the rotating connecting head 5 is formed with an external thread that is threaded to the connecting screw hole. The end of the rotating connecting head 5 close to the first protective pipe 1 is integrally formed with a force-bearing head 6. The vertical cross section of the force-bearing head 6 is a regular hexagon.

[0017] In this embodiment: when the two protective devices are connected, the rotating connector 5 at one end of the unfixed protective device is threaded to the fixed connector sleeve 4 at one end of the fixed protective device. During the threaded connection process, a wrench is used to engage with the outer side of the force-receiving head 6 and drive the force-receiving head 6 to rotate. The force-receiving head 6 drives the rotating connector 5 to rotate, thereby realizing the complete connection mechanism between the rotating connector 5 and the fixed connector sleeve 4.

[0018] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3The limiting mechanism includes a fixing ring 7 integrally formed on the outer periphery of the first protective pipe 1 and the second protective pipe 2 near the protective corrugated pipe 3. The outer periphery of the two fixing rings 7 is provided with a connecting groove 11 in the shape of a "U". The inner wall of the connecting groove 11 is engaged with a limiting rod 9. The two ends of the outer periphery of the limiting rod 9 are integrally formed with limiting plates 10. The two limiting plates 10 respectively abut against the side of the two fixing rings 7 that are close to each other. The outer periphery of the limiting rod 9 is threaded with a limiting nut.

[0019] In this embodiment: after the two protective devices are connected end to end by the connecting mechanism, the limiting rod 9 is inserted into the two connecting slots 11, and the limiting plate 10 and the two fixing rings 7 are brought close to each other. Then, the limiting nut is threaded onto the external thread of the limiting rod 9 and tightened to limit the protective bellows 3 to the current length. At this time, the length of the protective bellows 3 is limited, so the first protective tube 1 cannot move. Therefore, the connection mechanism is prevented from becoming loose, and the stability of the connection mechanism after connection is ensured.

[0020] Please refer to this carefully. Figure 2 The inner circumference of the rotating connector 5 is integrally formed with a rotating ring having a "convex" shaped cross-section, and the outer circumference of the first protective pipe 1 is provided with a rotating groove for the rotating ring to rotate.

[0021] In this embodiment: when the rotating connector 5 and the fixed connecting sleeve 4 are connected by threads, the rotating connector 5 drives the rotating ring to rotate in the rotating groove, thereby achieving the purpose of rotating the rotating connector 5.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
