Description

Technical Field

[0001] This invention relates to the field of power line protection technology, specifically to a power line protection device. Background Technology

[0002] During cable or wire installation, power guy wire protection devices are safety facilities used to protect the steel guy wires of cables or power poles. They are mostly made of reflective modified composite materials, which can work stably in environments ranging from -40℃ to 60℃. They have UV resistance and high voltage resistance, and a service life of over 10 years. Some models are also equipped with solar-powered audible and visual warning functions. They protect the guy wires themselves, resisting external impacts, corrosion, and aging, reducing the risk of guy wire wear and breakage, ensuring the stability of power poles, cables, or wires, improving power grid stability, and ensuring public safety. They allow pedestrians and vehicles to notice the presence of guy wires from a distance, avoiding collision accidents. At the same time, their insulation performance can prevent the risk of electric shock caused by exposed guy wires. They are an important means of ensuring the safety of power facilities and the public.

[0003] Power line protection devices typically employ a longitudinally slit round tube structure. The grooves allow for quick installation by easily fitting the device over the outside of the power line. They are compatible with different specifications of power lines, and the red and white or black and yellow reflective markings on the surface enhance the warning effect. Two types of round tubes, one thick and one thin, are usually used to protect the grounding part and the other the power line part, respectively.

[0004] The inventors of this application discovered in their research that the core defect of the prior art is that, in order to ensure the normal installation of the power line protection device, the thick power line protection tube and the thin power line protection tube are usually installed separately, and the limit is usually set by threaded fixing, which makes the assembly of the thick power line protection tube and the thin power line protection tube inconvenient. Summary of the Invention

[0005] This invention provides a power line protection device that solves the problem of inconvenient assembly of thick and thin power line protection tubes, achieving the effect of convenient assembly of the power line protection device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power cable protection device, comprising a protective inner tube, a limiting body fixedly connected inside the protective inner tube, a hollow tube fixedly connected inside the limiting body, an inner sliding rod slidably connected inside the hollow tube, an inner slider fixedly connected to one end of the inner sliding rod, an inner slider slidably connected to the outside of the inner slider inside the limiting body, a return spring fixedly connected to one side of the inner slider through the inside of the limiting body, a plug-in block fixedly connected to one side of the inner slider, an auxiliary groove provided at the bottom of the plug-in block, a connecting pipe fixedly connected to the top of the protective inner tube, a plug-in connector inserted into the connecting pipe, plug-in grooves provided on both sides of the plug-in connector, and the protective inner tube being made of high-elasticity TPU.

[0007] By adopting the above technical solution, the insertion tube is inserted into the inside of the connecting tube, and insertion slots are provided on both sides of the insertion tube. After the insertion tube is inserted into the inside of the connecting tube, the insertion tube pushes the insertion locking block to retract into the inside of the limiting body, and the return spring is compressed until the insertion locking block is inserted into both sides of the insertion slot, and the insertion tube is locked and limited. Furthermore, because of the auxiliary slot, the insertion tube cannot be disassembled by lifting, which further facilitates the insertion and installation of the protective device and solves the problem that the protective device cannot be easily assembled.

[0008] Preferably, the insertion tube is fixedly connected to the outside with a horizontal strip, the bottom of the horizontal strip is fixedly connected with a vertical strip, and the insertion tube is fixedly connected to the outside with a rotating strip.

[0009] Preferably, the top of the insertion tube is connected to a protective thin tube, and a thin tube reflective strip is fixedly connected to the outside of the protective thin tube.

[0010] Preferably, the top of the connecting pipe is provided with a horizontal limiting groove, and the inside of the connecting pipe is provided with a vertical limiting groove.

[0011] Preferably, a rotating ring is fixedly connected to the outside of the connecting pipe, and an outer pipe connecting ring is rotatably connected to the outside of the connecting pipe and the rotating ring.

[0012] Preferably, a protective outer tube is fixedly connected to the outside of the outer tube connecting ring, and a reflective strip is fixedly connected to the outside of the protective outer tube. The material of the protective outer tube is high-elasticity TPU.

[0013] By adopting the above technical solution and the design of the inner and outer tubes, after the plug is inserted, the horizontal and vertical strips are inserted into the inside of the connecting tube. This allows the rotation of the protective thin tube to drive the inner protective tube to rotate inside the outer protective tube, causing the gaps between the inner and outer protective tubes to misalign and abut. Furthermore, the gaps of the protective thin tubes face the ground, further increasing the sealing performance of the power line protection device and reducing the amount of rainwater entering the inside of the power line protection device through the gaps.

[0014] Preferably, an outer tube buffer pad is fixedly connected inside the protective outer tube, the outer tube buffer pad being made of rubber rings, and a metal hoop is fixedly connected outside the protective outer tube, the metal hoop being made of nickel-titanium alloy.

[0015] Preferably, the metal hoop has an inner metal strip that is slidably connected inside, the inner metal strip being made of nickel-titanium alloy, and a fixing bolt being inserted inside the inner metal strip.

[0016] Preferably, the external thread of the fixing bolt is connected to a fixing nut, and the internal thread of the fixing nut is connected to both ends of the fixing bolt.

[0017] Preferably, an inner tube buffer pad is fixedly connected inside the protective inner tube, and a hollow tough strip is fixedly connected outside the inner tube buffer pad. The hollow tough strip is made of thermoplastic polyurethane, and a reinforcing hoop is fixedly connected outside the protective inner tube. The reinforcing hoop is made of nickel-titanium alloy.

[0018] By adopting the above technical solutions, the inner and outer tubes are designed with a hollow separation design, thereby increasing the strength of the power line protection device. In addition, the inner tube buffer pad and the outer tube buffer pad increase the three-dimensionality of the power line protection device, while also reducing the impact force on the power line when it is hit. Furthermore, the hollow tough strip and reinforcing hoop are set to increase the strength of the inner tube.

[0019] This invention provides a power line protection device. It has the following advantages: 1. This invention provides a connector that is inserted into the inside of a connecting pipe, with insertion slots on both sides of the connector. After the connector is inserted into the connecting pipe, it pushes the insertion locking block to retract into the limiting body, causing the return spring to be compressed. The connector is locked and limited until the insertion locking block is inserted into both sides of the insertion slot. Furthermore, because of the auxiliary slots, the connector cannot be disassembled by lifting, thus facilitating the installation of the protective device and solving the problem of the protective device being difficult to assemble.

[0020] 2. By designing inner and outer protective tubes, this invention allows the inner and outer protective tubes to rotate within the outer protective tube after the horizontal and vertical strips are inserted into the connecting tube. This causes the gaps between the inner and outer protective tubes to misalign and abut, with the gaps of the inner and outer protective tubes facing the ground. This further enhances the sealing of the power cable protection device and reduces the amount of rainwater entering the device through the gaps.

[0021] 3. This invention increases the strength of the power cable protection device by setting up a protective inner and outer tube design and adopting a hollow separation design. In addition, the inner tube buffer pad and the outer tube buffer pad increase the three-dimensionality of the power cable protection device, while reducing the impact force on the power cable when the power cable protection device is hit. Furthermore, the hollow tough strip and reinforcing hoop increase the strength of the protective inner tube. Attached Figure Description

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see the appendix Figure 1 - Appendix Figure 11 This invention provides a power cable protection device, including a protective inner tube 6. A limiting body 10 is fixedly connected inside the protective inner tube 6. A hollow tube 25 is fixedly connected inside the limiting body 10. An inner slide rod 26 is slidably connected inside the hollow tube 25. An inner slider 28 is fixedly connected to one end of the inner slide rod 26. The inner slider 28 is slidably connected to the inside of the limiting body 10. A return spring 27 is fixedly connected to one side of the inner slider 28 through the inside of the limiting body 10. A plug-in block 29 is fixedly connected to one side of the inner slider 28. An auxiliary groove 30 is provided at the bottom of the plug-in block 29. A connecting tube 11 is fixedly connected to the top of the protective inner tube 6. A plug-in pipe 12 is inserted into the inside of the connecting tube 11. Plug-in grooves 17 are provided on both sides of the plug-in pipe 12. The protective inner tube 6 is made of high-elasticity TPU.

[0026] Specifically, the inner protective tube 6 can be installed outside the power cable using the gap on one side, and the plug tube 12 can also be installed outside the power cable using the gap on one side. During the insertion of the plug tube 12 and the connecting tube 11, the gaps of the inner protective tube 6 and the plug tube 12 are mirror images of each other.

[0027] During the insertion process of the connector 12, the connector 12 will abut against the top of the connector block 29, causing the connector block 29 to drive the inner slider 28 to retract into the interior of the limiting body 10, and the inner slider 26 to slide inside the hollow tube 25. The return spring 27 is compressed until the connector block 29 is aligned with the connector slot 17. Then, the return spring 27 will pop the connector block 29 out and lock it into both sides of the connector 12, thereby limiting the insertion and removal of the connector 12.

[0028] Please see the appendix Figure 5 , Figure 6 , Figure 7 , Figure 8 and attached Figure 10 The external fixed connection of the insertion tube 12 is a horizontal strip 15, the bottom of the horizontal strip 15 is fixedly connected to a vertical strip 16, and the external fixed connection of the insertion tube 12 is a rotating strip 13.

[0029] The top of the insertion tube 12 is connected to a protective thin tube 3, and a thin tube reflective strip 4 is fixedly connected to the outside of the protective thin tube 3.

[0030] A horizontal limiting groove 22 is provided at the top of the connecting pipe 11, and a vertical limiting groove 23 is provided inside the connecting pipe 11.

[0031] A rotating ring 24 is fixedly connected to the outside of the connecting pipe 11, and an outer pipe connecting ring 14 is rotatably connected to the outside of the connecting pipe 11 and the rotating ring 24.

[0032] The outer tube connecting ring 14 is externally fixedly connected to a protective outer tube 1, and the protective outer tube 1 is externally fixedly connected to an outer tube reflective strip 2. The material of the protective outer tube 1 is high-elasticity TPU.

[0033] Specifically, after the insertion tube 12 is inserted into the connecting tube 11, the protective thin tube 3 and the protective inner tube 6 will be assembled and fixed. During this process, the horizontal strip 15 and the vertical strip 16 will be inserted into the horizontal limiting groove 22 and the vertical limiting groove 23 respectively. At the same time, the outer tube connecting ring 14 can be rotated outside the connecting tube 11 using the rotating ring 24, further realizing the function of rotating connection between the protective outer tube 1 and the protective inner tube 6.

[0034] After rotating the insertion pipe 12 using the rotating bar 13, the inner protective pipe 6 and the outer protective pipe 1 will rotate as a whole, causing the gaps between the inner protective pipe 6 and the outer protective pipe 1 to be misaligned. This also ensures that the gap on one side of the protective thin tube 3 is on the same side as the gap on one side of the protective inner tube 6, and that the gap on one side of the protective thin tube 3 is on the side facing the ground as the gap on one side of the protective inner tube 6.

[0035] Please see the appendix Figure 5 , Figure 6 and attached Figure 9The outer tube 1 is internally fixedly connected to an outer tube buffer pad 18, which is made of rubber ring. The outer tube 1 is externally fixedly connected to a metal hoop 5, which is made of nickel-titanium alloy.

[0036] The metal hoop 5 has an inner metal strip 19 that slides inside. The inner metal strip 19 is made of nickel-titanium alloy and has a fixing bolt 20 inserted inside it.

[0037] The external thread of the fixing bolt 20 is connected to the fixing nut 21, and the internal thread of the fixing nut 21 is connected to both ends of the fixing bolt 20.

[0038] The inner tube 6 is internally fixedly connected to an inner tube buffer pad 9, and the inner tube buffer pad 9 is externally fixedly connected to a hollow tough strip 7. The hollow tough strip 7 is made of thermoplastic polyurethane. The inner tube 6 is externally fixedly connected to a reinforcing hoop 8, which is made of nickel-titanium alloy.

[0039] Specifically, the outer protective tube 1 and the thin protective tube 3 adopt a hollow design and are buffered by the outer tube buffer pad 18. The inner tube buffer pad 9 is in direct contact with the guy wire, so that when the power guy wire protection device is impacted, the outer tube buffer pad 18 and the inner tube buffer pad 9 will buffer the impact and reduce the impact on the guy wire.

[0040] The metal hoop 5 is fixed to the outside of the protective outer tube 1 and is made of nickel-titanium alloy. This allows the metal hoop 5 to be bent according to the installation requirements of the protective outer tube 1. At the same time, the inner metal strip 19 can slide inside the metal hoop 5. After the fixing bolt 20 is inserted, the fixing nut 21 is used to limit the position, thereby playing a role in reinforcing the protective outer tube 1.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
