As an important device for power transmission and distribution, power cables play an irreplaceable role in modern society. In order to protect power cables from external factors such as mechanical damage, chemical corrosion and moisture, some protective pipes are provided outside power cables. These protective pipes can effectively isolate potential threats such as mechanical pressure, chemical substances, moisture, corrosion and electromagnetic interference, thereby extending the service life of power cables.

[0003] Ordinary PVC protection sleeves have a single function and cannot protect cables well;

A screw positioning hole, a positioning screw, a spiral positioning sleeve and a stainless steel support ring structure are added outside the cable protection pipe, which can enhance the pressure resistance and impact resistance of specific parts of the cable protection pipe and achieve stable protection of the internal cable.

[0005] When the above technical solution is actually implemented, the stainless steel support ring structure is relatively single, composed of stainless steel rings with different thicknesses, and the achievable impact resistance is limited. Summary of the Invention

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] The present invention provides a technical solution:

[0027] Please refer to Figures 1 to 4 , a power cable protection pipe with an adjustable reinforcement structure, including a protective tube body 1, a group of enhanced positioning tubes 4 for positioning are threadedly connected between two groups of protective tube bodies 1, an external enhancement sleeve 3 is movably connected to the outside of the enhanced positioning tube 4, and a buffer enhancement component 2 for buffer protection is arranged between the external enhancement sleeve 3 and the enhanced positioning tube 4;

[0028] The buffer enhancement component 2 includes a rubber plate 201 that abuts against the outer wall of the enhanced positioning tube 4, and a buffer spring 202 is fixedly arranged between the rubber plate 201 and the inner wall of the external enhancement sleeve 3. A damping telescopic rod 203 passes through the inside of the buffer spring 202, and both ends of the damping telescopic rod 203 are respectively connected to the rubber plate 201 and the inner wall of the external enhancement sleeve 3. The buffer springs 202 are located at the four corners of the rubber plate 201, and a connecting rod 204 is arranged in the middle of the rubber plate 201. The connecting rod 204 passes through the external enhancement sleeve 3 and is provided with a fixing cap 205, and pull plates 206 are arranged on the left and right sides of the fixing cap 205. The outer diameter of the fixing cap 205 is larger than the outer diameter of the connecting rod 204, and a connection hole is opened at the connection part of the connecting rod 204 and the external enhancement sleeve 3. The rubber plate 201 is in an arc-shaped structure, and the rubber plates 201 are evenly distributed at equal distances about the vertical center line of the protection tube body 1. The rubber plate 201 is elastically connected to the external enhancement sleeve 3 through the buffer spring 202 and the damping telescopic rod 203.

[0029] By adopting the above technical solution, according to the protection requirements of the cable, a suitable enhanced positioning tube 4 is installed between the protection tube bodies 1. The outer diameter of the enhanced positioning tube 4 is smaller than the outer diameter of the protection tube body 1, so as to prevent the buffer enhancement component 2 from shaking and shifting. When an impact occurs at the position of the buffer enhancement component 2, the external acting force can reach the rubber plate 201 through the external enhancement sleeve 3. Since the buffer spring 202 and the damping telescopic rod 203 are arranged between the rubber plate 201 and the external enhancement sleeve 3, the external acting force can be buffered, thereby further improving the protection effect on the cable.

[0030] Specifically, as Figure 2 and Figure 4 shown, the top of the protection tube body 1 is provided with internal threads, and the bottom of the protection tube body 1 is provided with external threads. The protection tube body 1 includes a chlorinated rubber paint layer 101, an epoxy resin layer 102, a carbon fiber tube 103, and a PVC inner tube 104 arranged in sequence from outside to inside. The carbon fiber tube 103 and the PVC inner tube 104 are bonded to each other. The top of the enhanced positioning tube 4 is provided with internal threads, and the bottom of the enhanced positioning tube 4 is provided with external threads. The internal threads and external threads on the enhanced positioning tube 4 are adapted to the internal threads and external threads on the protection tube body 1.

[0031] By adopting the above technical solution, the protection tube body 1 is composed of a carbon fiber tube 103 and a PVC inner tube 104, which has higher impact resistance than a traditional PVC protection tube. And by providing the chlorinated rubber paint layer 101 and the epoxy resin layer 102 on the surface of the carbon fiber tube 103, the waterproof and corrosion resistance of the protection tube body 1 can be improved. Since the tops of both the protection tube body 1 and the enhanced positioning tube 4 are provided with internal threads, and the bottoms of both the protection tube body 1 and the enhanced positioning tube 4 are provided with external threads, the protection tube body 1 and the enhanced positioning tube 4 can be assembled arbitrarily, with stronger adaptability.

[0032] Working principle: Install the enhanced positioning tube 4 at the position where protection needs to be increased, and assemble the protection tube body 1 and the enhanced positioning tube 4 arbitrarily according to needs. Pull the pull plate 206, and the pull plate 206 drives the connecting rod 204 to move through the fixing cap 205, thereby driving the rubber plate 201 to move, adjusting the distance between the rubber plate 201 and the external enhanced sleeve 3, so that the rubber plate 201 can be smoothly sleeved on the protection tube body 1 and reach the position of the enhanced positioning tube 4. Loosen the fixing cap 205 to make the rubber plate 201 abut against the enhanced positioning tube 4. When an impact occurs at the position of the buffer enhancement assembly 2, the external force can reach the rubber plate 201 through the external enhanced sleeve 3. Since there are buffer springs 202 and damping telescopic rods 203 between the rubber plate 201 and the external enhanced sleeve 3, the external force can be buffered, thereby further improving the protection effect on the cable.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
