Description

Technical Field

[0001] This utility model relates to the technical field of outdoor power engineering, and in particular to a wear-resistant outdoor cable conduit structure. Background Technology

[0002] In outdoor power engineering, cable conduits are the core component that protects cables from damage by the external environment. They need to withstand complex outdoor working conditions for a long time, such as soil friction and heavy object compression. Therefore, a wear-resistant outdoor cable conduit structure is particularly needed.

[0003] Traditional conduits are mostly closed tubular structures with openings at both ends. When threading cables, the cable must be completely inserted from one end. If the cable is long or there are many cables, cable tangling and jamming are likely to occur. When inspecting cables in traditional conduits, although some conduits have reserved inspection slots, there is no temporary shielding structure. Soil and debris can easily enter the conduit during inspection, requiring additional cleaning.

[0004] To address the aforementioned issues, a wear-resistant outdoor cable conduit structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a wear-resistant outdoor cable conduit structure to solve the problems of the existing wear-resistant outdoor cable conduit structures mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wear-resistant outdoor cable conduit structure, comprising a conduit body, a sleeve fitted on the outer side of the conduit body, a cable passage groove extending through the top of the conduit body, sliding grooves on the outer walls of the conduit body on both sides of the cable passage groove, a locking groove at one end of the sliding groove, a baffle for blocking the cable passage groove slidably connected inside one side of the sliding groove, a locking block adapted to the locking groove at one end of the baffle, and a silicone pad on the side of the baffle facing the cable passage groove.

[0007] Preferably, the sleeve is provided with a sealing plate and an inner positioning plate inside. The sealing plate passes through the connection part of the wire groove, and the inner positioning plate is located inside the tube body. The sealing plate and the inner positioning plate are respectively attached to the outer wall and inner wall of the tube body.

[0008] Preferably, the inner positioning plate is provided in two sets, and a partition plate is provided between the two sets of inner positioning plates. The partition plate is used to separate the cables inside the tube.

[0009] Preferably, sealing strips are provided on both sides of the sealing plate.

[0010] Preferably, the outer surface of the tube is coated with a wear-resistant coating, and a reinforcing layer is provided inside the tube wall.

[0011] Preferably, the reinforcing layer is a glass fiber layer with a mesh structure.

[0012] Preferably, the outer surface of the sealing plate has a raised structure to increase friction.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This device has pre-set sliding grooves on both sides of the cable tray. During maintenance, you only need to slide the baffle along the sliding groove so that the locking block at one end of the baffle slides from the original locking groove into the locking groove on the other side to complete the positioning. The whole process does not require any additional tools and can quickly cover the cable tray. Compared with the traditional pipe installation, which involves the cumbersome process of finding obstructions before maintenance and cleaning up debris after maintenance, this device greatly simplifies the operation steps and reduces the labor intensity of the staff. 2. A through-type cable tray is opened at the top of the device tube. When threading the cable, there is no need to thread the cable through both ends of the tube. The cable can be directly placed into the tube through the cable tray. This is especially suitable for laying multiple cables or long-distance cables, avoiding cable tangling and jamming, and greatly shortening the threading time. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Example like Figure 1-3As shown, it includes a tube body 1, a sleeve 2 is sleeved on the outside of the tube body 1, a wire-passing groove 3 is opened through the top of the tube body 1, and sliding grooves 4 are provided on the outer walls of the tube body 1 on both sides of the wire-passing groove 3. A slot 5 is opened at one end of the sliding groove 4, and a baffle 6 for blocking the wire-passing groove 3 is slidably connected in one side of the sliding groove 4. A locking block 7 that matches the slot 5 is provided at one end of the baffle 6, and a silicone pad 8 is provided on the side of the baffle 6 facing the wire-passing groove 3.

[0018] It should be noted that, in this embodiment, a wear-resistant outdoor cable conduit structure includes a conduit body 1, which is injection molded from CPVC material, possessing good insulation and corrosion resistance. A sleeve 2, made of high-density polyethylene, is fitted onto the outer side of the conduit body 1, forming a double-layer protective structure. A cable-passing groove 3 is provided through the top of the conduit body 1 along its axial length, facilitating direct insertion of the cable into the conduit body 1. Sliding grooves 4 are symmetrically arranged on the outer walls of the conduit body 1 on both sides of the cable-passing groove 3, one end of which extends into the interior of the conduit body 1, and the other end... A circular slot 5 is provided, and a baffle 6 is slidably connected in the groove 4. The baffle 6 is made of rigid PVC material, and its length matches the wire groove 3, while its width is slightly larger than the wire groove 3. Silicone pads 8 are glued to both sides of the baffle 6. The thickness of the silicone pads 8 is 2mm. When the baffle 6 is closed, the silicone pads 8 are tightly fitted to the side wall of the slot 5 to form a seal. One end of the baffle 6 is integrally formed with a locking block 7 that matches the slot 5. The locking block 7 is made of elastic plastic, and its outer periphery is consistent with the surface of the tube body 1 without any protrusions. When the baffle 6 slides to the position of the slot 5, the locking block 7 gradually engages in the slot 5 to achieve positioning. The outer surface of the tube body 1 is uniformly coated with a wear-resistant coating 13. The coating material is epoxy resin with a thickness of 0.5-1mm, which can improve the wear resistance of the tube body 1. A reinforcing layer 14 is embedded in the tube wall of the tube body 1. The reinforcing layer 14 is a glass fiber layer with a mesh structure and a mesh size of 5mm×5mm, which can significantly improve the impact strength and pressure resistance of the tube body 1. The outer surface of the sealing plate 9 is integrally formed with a uniformly distributed protrusion structure with a protrusion height of 1mm, which can increase the friction when gripping without affecting the connection between the tube body 1 and the sleeve 2.

[0019] like Figure 4 , 5 As shown, the sleeve 2 is provided with a sealing plate 9 and an inner positioning plate 10 inside. The sealing plate 9 passes through the connection part of the wire groove 3. The inner positioning plate 10 is located inside the tube body 1, and the sealing plate 9 and the inner positioning plate 10 are respectively attached to the outer wall and the inner wall of the tube body 1. There are two sets of inner positioning plates 10, and a partition plate 11 is provided between the two sets of inner positioning plates 10. The partition plate 11 is used to separate the cables inside the tube body 1. Sealing strips 12 are provided on both sides of the sealing plate 9. The outer surface of the tube body 1 is coated with a wear-resistant coating 13. A reinforcing layer 14 is provided inside the tube wall of the tube body 1.

[0020] It should be noted that the sleeve 2 is equipped with a sealing plate 9 and an inner positioning plate 10, which are integrally formed. The width of the sealing plate 9 matches the wire groove 3 and can pass through the wire groove 3 for fixation. The sealing plate 9 is located on the outside of the tube body 1, and the inner positioning plate 10 is located on the inside of the tube body 1. Both are tightly fitted to the outer wall and inner wall of the tube body 1, respectively, forming a double fixation. Sealing strips 12 are embedded on both sides of the sealing plate 9. The sealing strips 12 are made of nitrile rubber, which can further enhance the sealing performance of the wire groove 3. There are two sets of inner positioning plates 10. A partition plate 11 is vertically arranged between the two sets of inner positioning plates 10. The partition plate 11 divides the inside of the tube body 1 into two independent chambers, which can accommodate different types of cables respectively.

[0021] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-5 The assembly with sealing plate 9, inner positioning plate 10 and partition plate 11 is inserted from one end of the pipe body 1. The sealing plate 9 passes through the wire groove 3. The sealing plate 9 and the inner positioning plate 10 are respectively attached to the outer wall and inner wall of the pipe body 1 to achieve fixation. The partition plate 11 separates the cables inside the tube 1 to prevent mutual interference, and at the same time supports the inner cavity of the tube 1 to improve the resistance to compression. The sealing strips 12 on both sides of the sealing plate 9 further enhance the sealing of the cable groove 3. The wear-resistant coating 13 on the outside of the tube body 1 improves the wear resistance, and the glass fiber reinforcement layer 14 inside the tube wall enhances the structural strength; If cable maintenance is required, the worker holds the outer surface of the sleeve 2 and applies a pulling force to the outside of the tube 1. Since the sealing plate 9 penetrates the cable groove 3 and the two are fixed only by adhering to the outer and inner walls of the tube 1, the pulling force can cause the connection to detach from the cable groove 3, thereby pulling out the whole assembly consisting of the sealing plate 9, the inner positioning plate 10 and the partition plate 11 from the tube 1. After the cable that needs maintenance or replacement is pulled out, slide the baffle 6 along the slide groove 4, so that the locking block 7 at one end of the baffle 6 is released from the positioning constraint of the original locking groove 5, until the locking block 7 of the baffle 6 is gradually locked into the locking groove 5 on the other side to achieve positioning. At this time, the baffle 6 completely covers the cable groove 3, temporarily blocking the cable groove 3, protecting the cable that has not been pulled out in the tube 1, and preventing debris from entering the tube 1 during maintenance and making it inconvenient to clean.

[0022] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
