Description

Technical Field

[0001] This utility model relates to the field of power pipe technology, specifically to an MPP power pipe that prevents cables from getting tangled. Background Technology

[0002] With the acceleration of urbanization and the continuous growth of electricity demand, cable transmission systems are playing an increasingly important role in the construction of urban power supply, communication and other infrastructure. A large number of cables need to be laid in underground pipelines to achieve safe and stable power and signal transmission.

[0003] Some power conduits have simple structures, mostly only possessing basic cable-carrying functions and lacking effective anti-tangle designs. When multiple cables are simultaneously inserted into traditional power conduits, the lack of proper partitioning and guidance within the conduit space easily leads to cable contact and entanglement. This entanglement not only increases the cable's frictional resistance, making cable insertion and extraction difficult, but may also cause wear and damage to the cable surface, reducing its service life. Therefore, an MPP power conduit designed to prevent cable entanglement is proposed to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an MPP power conduit that prevents cable tangling, possessing advantages such as anti-tangling and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An MPP power conduit for preventing cable tangling includes a base, a sealing block, and a conduit body, wherein the inner side of the conduit body is provided with an anti-tangling component for preventing cable tangling.

[0007] The anti-winding component includes four guide sleeves fixedly connected to the inside of the tube body, four ball bearings on the inside of the guide sleeves, and a separator fixedly connected to the inside of the tube body.

[0008] Furthermore, the partition frame is X-shaped, and the partition frame divides the interior of the tube into four fixed spaces, with the guide sleeve located inside the corresponding fixed space.

[0009] Furthermore, the inner side of the guide sleeve has four grooves that are adapted to the ball bearings. The ball bearings are slidably connected to the inner side of the corresponding grooves, and the four grooves are respectively arranged on the inner top wall, inner bottom wall, inner left side wall and inner right side wall of the guide sleeve.

[0010] Furthermore, an outer sheath is fixedly connected to the outside of the tube body, and the outer sheath adopts a three-layer co-extrusion structure, with the inner layer being ethylene-vinyl acetate copolymer, the middle layer being flame-retardant polyurethane, and the outer layer being fluorinated ethylene propylene copolymer.

[0011] Furthermore, the top of the inner side of the base and the bottom of the inner side of the sealing block are both provided with receiving openings that are adapted to the tube body.

[0012] Furthermore, the sealing block has fixing openings on both the left and right sides, and a frame is fixedly connected to the inner side of each fixing opening.

[0013] Furthermore, a transmission rod is rotatably connected to the inner side of the frame, a transmission gear is fixedly connected to the bottom end of the transmission rod, a driven gear meshes with the bottom of the transmission gear, a threaded rod is fixedly connected to the inner side of the center of the driven gear, a threaded block is threadedly connected to the outer side of the threaded rod, and a locking rod is fixedly connected to the opposite side of the threaded blocks on both the left and right sides.

[0015] Compared with the prior art, this utility model provides an MPP power conduit to prevent cable tangling, which has the following beneficial effects:

[0016] This MPP power conduit, designed to prevent cable tangling, uses an "X"-shaped divider to separate the interior of the conduit into four independent fixed spaces.

[0021] 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.

[0022] Please see Figures 1 to 3 The MPP power pipe for preventing cable tangling in this embodiment includes a base 1, a sealing block 2 and a pipe body 3. The inner side of the pipe body 3 is provided with an anti-tangling component for preventing cable tangling.

[0023] Please see Figure 1 In this embodiment, the anti-winding component includes four guide sleeves 4 fixedly connected to the inner side of the tube body 3, four ball bearings 5 ​​are provided on the inner side of the guide sleeves 4, and a separator 6 is fixedly connected to the inner side of the tube body 3.

[0024] Specifically, the divider 6 is X-shaped and divides the interior of the tube 3 into four fixed spaces, with the guide sleeve 4 located inside the corresponding fixed space.

[0025] It should be noted that this separation method makes each fixed space relatively independent. When multiple cables are run through the pipe 3, different cables can be placed in different fixed spaces, which effectively avoids the cables from getting tangled together in terms of spatial layout.

[0026] Specifically, the inner side of the guide sleeve 4 is provided with four grooves that are adapted to the ball 5. The ball 5 is slidably connected to the inner side of the corresponding groove, and the four grooves are respectively arranged on the inner top wall, inner bottom wall, inner left side wall and inner right side wall of the guide sleeve 4.

[0027] It should be noted that the four grooves on the inner side of the guide sleeve 4 are designed with arc-shaped grooves, forming a rolling fit with the spherical surface of the ball 5, allowing the cable to move smoothly along the axial direction when it enters the tube 3, avoiding cable twisting caused by friction. The ball 5 is made of wear-resistant nylon material to reduce rolling resistance and wear.

[0028] Specifically, an outer sheath 7 is fixedly connected to the outside of the tube body 3, and the outer sheath 7 adopts a three-layer co-extrusion structure, with the inner layer being ethylene-vinyl acetate copolymer, the middle layer being flame-retardant polyurethane, and the outer layer being fluorinated ethylene propylene copolymer.

[0029] It should be noted that the inner ethylene-vinyl acetate copolymer provides flexibility; the middle flame-retardant polyurethane enhances fire resistance; and the outer fluorinated ethylene-propylene copolymer imparts corrosion resistance and UV resistance, making it suitable for complex buried environments.

[0030] Specifically, the top of the inner side of the base 1 and the bottom of the inner side of the sealing block 2 are both provided with receiving openings that are compatible with the tube body 3.

[0031] It should be noted that the receiving port can position and fix the tube body 3, preventing the tube body 3 from shaking or shifting between the base 1 and the sealing block 2.

[0032] Specifically, the sealing block 2 has fixed openings on both the left and right sides, and the inner sides of the two fixed openings are fixedly connected to the frame 8. The inner side of the frame 8 is rotatably connected to the transmission rod 9. The bottom end of the transmission rod 9 is fixedly connected to the transmission gear 10. The bottom of the transmission gear 10 is meshed with the driven gear 11. The inner side of the center of the driven gear 11 is fixedly connected to the threaded rod 12. The outer side of the threaded rod 12 is threadedly connected to the threaded block 13. The opposite sides of the threaded blocks 13 on both the left and right sides are fixedly connected to the locking rod 14. The top of the inner side of the base 1 has two slots that are compatible with the frame 8, and the inner side of the slots has a locking groove that is compatible with the locking rod 14.

[0033] It should be noted that the transmission rod 9, transmission gear 10, driven gear 11 and threaded rod 12 inside the frame 8 constitute a worm gear transmission system. By rotating the transmission rod 9, the threaded rod 12 is driven to rotate, which causes the threaded block 13 to drive the locking rod 14 to move horizontally, thereby realizing the rapid locking or separation of the base 1 and the sealing block 2.

[0034] The working principle of the above embodiments is as follows:

[0035] When the cable enters from the port of the tube 3, it is separated into four fixed spaces by the "X" shaped structure of the separator 6, which forcibly achieves physical isolation and prevents multiple cables from contacting each other. When the cable moves in the fixed space, its outer surface contacts the ball 5 in the guide sleeve 4. The ball 5 rolls freely in the groove, converting sliding friction into rolling friction, reducing the torsional force when the cable enters, thereby suppressing the cable spin-wrap caused by friction. In addition, the groove of the guide sleeve 4 only allows the ball 5 to roll along the axial direction of the tube 3, limiting the radial displacement of the cable and ensuring that the cable always maintains a straight arrangement.

[0036] Place the tube body 3 into the receiving opening of the base 1, and then place the sealing block 2 above the tube body 3, so that the frame body 8 is aligned with the slot on the base 1 and inserted, thus achieving the initial positioning of the sealing block 2 and the base 1. Rotate the transmission rod 9, which drives the transmission gear 10 to rotate. Since the transmission gear 10 meshes with the driven gear 11, the rotation of the transmission gear 10 drives the driven gear 11 to rotate. The rotation of the driven gear 11 causes the threaded rod 12, which is fixedly connected to it, to rotate. The rotation of the threaded rod 12 causes the threaded block 13 connected to the outer thread to move along the axial direction of the threaded rod 12. The threaded block 13 then drives the locking rod 14 to move, so that the locking rod 14 is inserted into the locking groove, thus achieving a rigid connection between the base 1 and the sealing block 2.

[0037] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
