Description

Technical Field

[0001] This invention relates to the field of rodent prevention technology for electrical conduits, specifically to a rodent-proof device for preventing electrical equipment conduits from being chewed. Background Technology

[0002] Rodent control in pipelines is a protective technology for various pipeline systems such as building water supply and drainage, gas, HVAC, and communications. It uses a combination of methods, including physical sealing, material reinforcement, and environmental management, to block the entry, gnawing, and climbing paths of rodents, thereby preventing pipeline damage, leakage, functional failure, and the spread of diseases. The key technical standard is that all gaps and mesh openings connecting pipelines to the outside world must be designed to prevent intrusion, cutting off the channels through which rodents come into contact with pipelines at the source.

[0003] Existing pipe rodent control methods involve adding natural repellents such as capsaicin, menthol, or camphor extract to the outer layer of the pipes, preventing rats from actively gnawing on electrical conduits. However, these methods utilize the pungent and irritating properties of capsaicin and the strong odor of menthol to stimulate the oral mucosa and olfactory nerves of rats, creating a conditioned reflex that makes rats actively avoid gnawing on the pipes. However, these materials have a short lifespan and cannot be effective in the long term, which can lead to a window of opportunity for rats to gnaw on the pipes. Furthermore, sealing the pipe openings requires the installation of covers that are compatible with the cables, and when additional cables are added to the pipes, the covers that are compatible with the cables need to be replaced. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides a rodent-proof device for preventing electrical equipment conduits from being chewed.

[0005] The technical solution adopted by the present invention to solve its technical problem is: an anti-rodent gnawing device for electrical equipment pipelines, including an inner tube, sealing components are provided at both ends of the inner tube, a reinforcing component is provided on the surface of the inner tube, and an isolation component is provided inside the inner tube; The sealing assembly includes a semi-cylinder that is snapped into the opening of the inner tube. A semi-circular arc plate is fixedly connected to the outer wall of the semi-cylinder, and multiple metal rods are fixedly connected to the inner wall of the semi-cylinder. A snap-fit ​​arc plate is snapped into the opening of the inner tube, and a splicing arc plate is fixedly connected to the outer wall of the snap-fit ​​arc plate. Multiple insertion holes are provided on the inner wall of the snap-fit ​​arc plate.

[0006] Specifically, the semi-cylinder and the snap-fit ​​arc plate are spliced ​​together to form a cylinder, and the same fixing ring is snapped onto the outer wall of the semi-cylinder and the snap-fit ​​arc plate.

[0007] Specifically, the upper end of the metal rod is inserted into the insertion hole on the inner wall of the snap-fit ​​arc plate, and the upper surface of the metal rod matches the outer wall of the snap-fit ​​arc plate.

[0008] Specifically, the reinforcing component includes two sealing rings, which are snapped onto both ends of the outer wall of the inner tube. Multiple rotating rings are rotatably sleeved on the outer wall of the inner tube. Multiple annular grooves are formed on the outer wall of the inner tube, and reinforcing rings are embedded inside the annular grooves. Multiple strip grooves are formed on the outer wall of the inner tube, and multiple notches are formed on the outer wall of the reinforcing rings.

[0009] Specifically, the groove and the notch are provided correspondingly, and the same reinforcing strip is engaged inside the groove and the notch.

[0010] Specifically, the inner wall of the sealing ring is provided with multiple slots, which are engaged with the surface of the reinforcing strip.

[0011] Specifically, the isolation assembly includes a collar that is movably fitted onto the inner wall of the inner tube. Multiple semicircular rings are fixedly connected to the inner wall of the collar, and a circular ring is fixedly connected to the outer wall of the semicircular rings.

[0012] The beneficial effects of this invention are: (1) The electrical equipment pipeline anti-rodent gnawing device of the present invention realizes flexible sealing and rodent protection of pipeline openings through the sealing component. The splicing design of the semi-cylinder and the snap-fit ​​arc plate allows for the addition of inserted cables between the metal rods. The cooperation between the metal rod and the socket not only enhances the stability of the splicing structure, but also uses the hardness of the metal material to block rodent gnawing. Different numbers of cables can be adapted without replacing the entire cover plate. The fixing ring reinforces the spliced ​​cylinder to prevent rodents from pulling and causing the sealing structure to loosen, further improving the reliability of rodent prevention.

[0013] (2) The electrical equipment pipeline anti-rodent gnawing device of the present invention enhances the overall structural strength of the inner pipe through the reinforcement component. The combination of the reinforcement ring and the reinforcement strip forms a double support. The setting of the rotating ring makes the pipeline quickly deflected when it is subjected to external force. The rotating ring disperses the force when the rodent gnaws, avoiding local damage to the inner pipe. At the same time, the design of the rotating ring makes it difficult for rodents to climb the pipeline, reducing their chance of contact with the pipeline. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1 to 7 The present invention provides the following technical solutions: Example 1: An anti-rodent gnawing device for electrical equipment conduits, comprising an inner tube 1, sealing components 2 at both ends of the inner tube 1, reinforcing components 3 on the surface of the inner tube 1, and an isolation component 4 inside the inner tube 1. The sealing assembly 2 includes a semi-cylinder 21, which is snapped into the opening of the inner tube 1. A semi-circular arc plate 22 is fixedly connected to the outer wall of the semi-cylinder 21, and multiple metal rods 23 are fixedly connected to the inner wall of the semi-cylinder 21. A snap-fit ​​arc plate 24 is snapped into the opening of the inner tube 1, and a splicing arc plate 25 is fixedly connected to the outer wall of the snap-fit ​​arc plate 24. Multiple insertion holes 26 are provided on the inner wall of the snap-fit ​​arc plate 24.

[0019] The semi-cylinder 21 and the snap-fit ​​arc plate 24 are spliced ​​together to form a cylinder. The same fixing ring 27 is snapped onto the outer wall of the semi-cylinder 21 and the snap-fit ​​arc plate 24. Through the splicing design of the semi-cylinder 21 and the snap-fit ​​arc plate 24, a complete cylindrical structure is formed, which precisely matches the opening size of the inner tube 1 and achieves complete coverage of the opening. This avoids leaving gaps for rodent intrusion due to incomplete structure. The snap-fit ​​function of the fixing ring 27 is to lock the spliced ​​semi-cylinder 21 and the snap-fit ​​arc plate 24 to prevent them from separating during rodent pulling, external vibration or cable adjustment, thus ensuring the stability and sealing of the sealing structure.

[0020] The upper end of the metal rod 23 is inserted into the insertion hole 26 on the inner wall of the snap-fit ​​arc plate 24. The upper surface of the metal rod 23 matches the outer wall of the snap-fit ​​arc plate 24. The metal rod 23 is made of hard metal, which rodents cannot gnaw and destroy. After it is inserted and fixed, it forms a horizontal protective barrier, blocking the path of rodents to gnaw on the inner tube 1 or cable through the opening. This makes up for the lack of timeliness of traditional natural repellents and achieves a long-term anti-gnawing effect.

[0021] In use, first select a semi-cylinder 21, a snap-fit ​​arc plate 24, and a fixing ring 27 that match the diameter of the inner tube 1. Check whether the metal rod 23 on the inner wall of the semi-cylinder 21 is intact and whether the insertion hole 26 on the inner wall of the snap-fit ​​arc plate 24 is unobstructed. Ensure that the diameter of the metal rod 23 and the diameter of the insertion hole 26 are precisely matched to avoid splicing gaps. Organize the electrical cables to be installed into a bundle, insert them from one end of the inner tube 1 and extend them to the other end, so that the cable bundle is located at the axis of the inner tube 1, leaving installation space for the sealing component 2. First, snap the cables that need to be inserted into the inner tube 1 between multiple metal rods 23. Then, splice the snap-fit ​​arc plate 24 and the semi-cylinder 21 together, so that the splicing arc plate 25 of the snap-fit ​​arc plate 24 and the semi-cylinder 21 are aligned. The arc plates 22 are aligned, and the metal rods 23 are precisely inserted into the insertion holes 26 of the snap-fit ​​arc plates 24 until the semi-cylinder 21 and the snap-fit ​​arc plates 24 are spliced ​​together to form a complete cylinder, completely covering the gap between the opening of the inner tube 1 and the cable bundle. Finally, the fixing ring 27 is put on from one end of the spliced ​​cylinder. The elastic clamping force of the fixing ring 27 is used to lock the semi-cylinder 21 and the snap-fit ​​arc plates 24 to prevent the splice from loosening due to the pulling of rodents. Then, the snap-fit ​​arc plates 24 and the semi-cylinder 21 are snapped in along the other side of the opening of the inner tube 1, so that the snap-fit ​​arc plates 24 and the semi-cylinder 21 seal the opening of the inner tube 1. Through the gap between the metal rods 23, the cable in the inner tube 1 can be added at will, and there is no need to replace the parts at the opening of the inner tube 1.

[0022] Example 2: The technical solution of this example, which differs from that of Example 1, includes: the reinforcing component 3 includes two sealing rings 31, which are snapped onto the two ends of the outer wall of the inner tube 1. Multiple rotating rings 32 are rotatably sleeved on the outer wall of the inner tube 1. Multiple annular grooves 33 are formed on the outer wall of the inner tube 1. Reinforcing rings 34 are embedded inside the annular grooves 33. Multiple strip grooves 35 are formed on the outer wall of the inner tube 1. Multiple notches 36 are formed on the outer wall of the reinforcing rings 34.

[0023] The groove 35 and the notch 36 are set accordingly. The same reinforcing strip 37 is snapped into the inside of the groove 35 and the notch 36. The reinforcing ring 34 is distributed around the inner tube 1 to enhance the radial anti-gnawing ability of the inner tube 1. The reinforcing strip 37 passes through the groove 35 and the notch 36 of the reinforcing ring 34 along the axial direction to form a cross-reinforcement structure, which disperses the local force when the rodent gnaws, avoids local damage to the inner tube 1, and significantly improves the overall structural strength and anti-damage ability of the inner tube 1.

[0024] Multiple slots 38 are provided on the inner wall of the sealing ring 31. The slots 38 are engaged with the surface of the reinforcing strip 37. The sealing ring 31 is made of elastic material. After being engaged with the outer walls of both ends of the inner tube 1, it fits tightly with the inner tube 1 and the mounting surface, sealing the gap between the outer wall of the inner tube 1 and the outside world. This blocks the path for rodents to enter the pipeline through the gaps from the source and supplements the sealing protection blind area of ​​the sealing component 2.

[0025] In use, annular grooves 33 are evenly distributed axially on the outer wall of the inner tube 1. Reinforcing rings 34 are then inserted one by one into the annular grooves 33, ensuring a tight fit between the reinforcing ring 34 and the inner wall of the annular groove 33 without loosening or displacement. The outer wall of the reinforcing ring 34 is flush with the outer wall of the inner tube 1 to avoid protrusions that could obstruct subsequent component installation. The reinforcing strip 37 is aligned axially with the strip groove 35 of the inner tube 1, ensuring its position corresponds to the notch 36 of the reinforcing ring 34. The reinforcing strip 37 is then inserted into the strip groove 35 until it passes through the notches 36 of all the reinforcing rings 34, achieving cross-reinforcement and dispersing the localized force exerted by rodent gnawing. Take a sealing ring 31 that matches the diameter of the inner tube 1, and put the sealing ring 31 on both ends of the inner tube 1 respectively. Slide it to both ends of the reinforcing strip 37 so that the groove 38 on the inner wall of the sealing ring 31 is precisely engaged with the end of the reinforcing strip 37. This not only fixes the axial position of the reinforcing strip 37, but also seals the gap between the inner tube 1 and the outside through the sealing ring 31, blocking the path of rodents to enter through the gap. Evenly fit multiple rotating rings 32 on the outer wall of the inner tube 1, between two sealing rings 31. The rotating rings 32 can rotate freely. When rodents try to climb the inner tube 1, the rotation of the rotating rings 32 will destroy the rodents' gripping force, thereby blocking their climbing path.

[0026] Example 3: The technical solution of this example that differs from that of Example 2 includes: the isolation component 4 includes a collar 41, which is movably sleeved on the inner wall of the inner tube 1. A plurality of semi-circular rings 42 are fixedly connected to the inner wall of the collar 41, and a circular ring 43 is fixedly connected to the outer wall of the semi-circular rings 42.

[0027] During use, check the connection strength of the collar 41, semi-circular ring 42, and circular ring 43 of the isolation component 4 to ensure that the semi-circular ring 42 is firmly fixed to the collar 41 and circular ring 43 without the risk of breakage. The semi-circular ring 42 can be slightly elastically deformed to adapt to cables of different diameters. Insert the collar 41 from one end of the inner tube 1 and slide it along the inner wall of the inner tube 1 to the middle position. Adjust the number of collars 41 according to the number of cables. Multiple collars 41 can be installed at intervals to ensure that the cables are supported throughout the entire length of the inner tube 1. Distribute the cable bundles passing through the inner tube 1 and embed them one by one into the gaps between the semi-circular rings 42. Use the elastic clamping force of the semi-circular rings 42 to fix individual cables and prevent them from tangling and squeezing. At the same time, maintain a certain distance between the cables to reduce the possibility of rodents passing through the gaps between the cables. The circular ring 43 further enhances the structural stability of the semi-circular ring 42 and prevents it from deforming under stress.
