Description

Technical Field

[0001] This utility model relates to the field of PE power pipe technology, specifically a PE power pipe with protective components. Background Technology

[0002] PE power pipe is a high-molecular material pipe specially used for laying power lines. It is mainly made of polyethylene (PE) and has excellent insulation properties, corrosion resistance, weather resistance and pressure resistance. In addition, PE power pipe also has the characteristics of anti-aging, impact resistance, high mechanical strength, long service life and excellent electrical insulation performance. It can be widely used in buried high-voltage cables, street light cable protection sleeves and other fields. When PE power pipes are laid overhead, the pipe body is exposed to the outside, so rainwater will wash away and adhere to the pipe body. The rainwater adhering to the pipe surface will soak the protective layer on the outer wall of the pipe for a long time, which can easily lead to the peeling of the protective layer from the base material. If the rainwater contains acidic components, the corrosion rate will be further accelerated, which will affect the service condition and service life of the pipe body. Therefore, to address the above problems, a PE power pipe with protective components is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a PE power pipe with protective components to solve the problems mentioned in the background art.

[0014] 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.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-7 This utility model provides a technical solution: A PE power conduit with protective components includes a conduit body 1, with connecting sleeves 2 connected to both ends of the conduit body 1. An upper rainproof component 3 is provided above the conduit body 1, and a lower rainproof component 4 is provided below the conduit body 1. A wiper component 5 is provided between the upper rainproof component 3 and the lower rainproof component 4. The upper rainproof component 3 includes a rainproof cover 31, which is semi-circular and located directly above the conduit body 1. The upper surface of the rainproof cover 31 has multiple first rain guide grooves 32, which are arranged at equal intervals. The cross-sectional shape of the first rain guide grooves 32 is semi-circular, and the connection between the first rain guide grooves 32 and the edge of the rainproof cover 31 is arc-shaped. The bottom of the rainproof cover 31 has symmetrical sliding grooves 33.

[0017] It should be noted that: Pipe body 1, as the core carrier of power transmission, has a sealed connection between the two ends through connecting sleeves 2 to ensure the integrity of the power cable after laying. Upper rainproof component 3 and lower rainproof component 4 are respectively set on the upper and lower parts of pipe body 1 to form a three-dimensional protective structure. The rainproof cover 31 of the upper rainproof component 3 is semi-circular and accurately covers the top of pipe body 1. Its arc-shaped contour can quickly guide rainwater. Multiple semi-circular first rain guide grooves 32 are equidistantly arranged on the upper surface. The grooves guide the rainwater to the edge of the rainproof cover 31. The arc-shaped connection design between the first rain guide groove 32 and the edge of the rainproof cover 31 avoids rainwater retention and reduces the long-term erosion of the structure by water accumulation on the surface of the rainproof cover 31. As a further implementation of this solution, the lower rainproof component 4 includes a rainproof sleeve 41, which is semi-circular and has its upper surface fitted with the lower surface of the tube body 1. An arc-shaped protrusion 42 is integrally formed at the bottom center of the rainproof sleeve 41. Multiple second rain guide grooves 43 are provided on the lower surface of the rainproof sleeve 41. The multiple second rain guide grooves 43 are inclined and are arranged at equal intervals. It should be noted that the rainproof sleeve 41 of the lower rainproof component 4 is also semi-circular, closely fitting the lower surface of the tube body 1, forming a support and protection for the bottom of the tube body 1. The multiple second rain guide grooves 43 on the lower surface are arranged at an inclined and equidistant distance, which can guide the rainwater attached to the rainproof sleeve 41 to both sides, further enhancing the rainproof effect. The arc-shaped protrusion 42 integrally formed at the bottom of the rainproof sleeve 41 can accelerate the gravity dripping effect of the raindrops when the raindrops adhering to the surface of the rainproof sleeve 41 slide off through its own shape. As a further implementation of this solution, multiple connecting semi-rings 44 are fitted on the top of the outer side of the pipe body 1. The multiple connecting semi-rings 44 are semi-circular, and the lower surface of the multiple connecting semi-rings 44 is in contact with the upper surface of the pipe body 1. The end of the connecting semi-ring 44 is fixedly connected to the top of the rainproof cover 41. A connecting rod 45 is provided between the connecting semi-ring 44 and the protective cover. The bottom end of the connecting rod 45 is fixedly connected to the top of the connecting semi-ring 44, and the top end of the connecting rod 45 is fixedly connected to the bottom of the rainproof cover 31. A gap is left between the rainproof cover 31 and the pipe body 1. It should be noted that: the multiple semi-circular connecting half-rings 44 fitted on the top of the outer side of the tube body 1 are used to securely connect the upper and lower rainproof components to the tube body 1 by attaching the bottom end to the tube body 1 and connecting the top end to the rainproof sleeve 41. The connecting rod 45 is vertically connected to the connecting half-rings 44 and the rainproof cover 31. A gap space is reserved between the rainproof cover 31 and the tube body 1. While ensuring the rainproof effect of the rainproof cover 31, it avoids the rainproof cover 31 directly pressing the tube body 1, and provides space for the tube body 1 to dissipate heat and for the rain wiper component 5 to move. As a further implementation of this solution, the wiper assembly 5 includes multiple wiper halves 51 disposed between adjacent connecting halves 44. The multiple wiper halves 51 are semi-circular. Wiper strips 52 are fixedly connected to the inner side of the wiper halves 51, and the lower surface of the wiper strips 52 is in contact with the upper surface of the tube body 1. A movable support rod 53 is fixedly connected to the top center of the wiper halves 51. A ball bearing 54 is rotatably embedded in the top center of the movable support rod 53. The ball bearing 54 is adapted to the sliding groove 33, and the upper part of the ball bearing 54 is disposed in the sliding groove 33. It should be noted that: multiple semi-circular wiper halves 51 are distributed between adjacent connecting halves 44. The wiper blades 52 on the inner side are closely attached to the upper surface of the tube body 1 and can remove raindrops from the upper surface of the tube body 1 as the assembly moves. The movable support rod 53 at the top of the wiper halves 51 cooperates with the sliding groove 33 at the bottom of the rain cover 31 through the ball bearing 54 at the top, so that the wiper assembly 5 can slide flexibly along the direction of the sliding groove 33. Under the scouring of rainwater or the push of wind, dynamic cleaning of the surface of the tube body 1 is achieved, avoiding the long-term adhesion of raindrops and the impact on the tube body 1. The overall structure, through the coordinated design of "top and bottom rainproofing + dynamic rain wipers", comprehensively enhances the rainproof capability of PE power pipes in outdoor environments.

[0018] Workflow: When encountering rainfall, the upper rainproof component 3 directly above the pipe body 1 takes the lead in providing protection. The semi-circular rainproof cover 31 covers the top of the pipe body 1, preventing rainwater from falling directly onto the surface of the pipe body 1. The rainwater falling on the upper surface of the rainproof cover 31 flows into multiple equidistant first rain guide channels 32 under the action of gravity. The first rain guide channel 32 has a semi-circular cross section, and the connection with the edge of the rainproof cover 31 adopts an arc transition design, which effectively reduces the resistance to rainwater flow and guides the rainwater to quickly drain along the first rain guide channel 32 to the two sides of the rainproof cover 31, avoiding the accumulation of rainwater on the surface of the rainproof cover 31. The lower rainproof component 4 below the pipe body 1 further enhances the protection. The upper surface of the semi-circular rainproof sleeve 41 is tightly fitted to the lower surface of the pipe body 1, forming a wrap-around protection for the bottom of the pipe body 1, preventing oblique rainfall or rain blown to the bottom of the pipe body 1 by wind. Multiple inclined second rain guide grooves 43 opened on its lower surface guide the diverted rainwater to drain quickly along the inclined direction. The arc-shaped protrusion 42 at the center of the bottom of the rainproof sleeve 41 allows the rainwater gathered through the second rain guide grooves 43 to drip quickly, avoiding rainwater from lingering at the bottom of the pipe body 1 for a long time and reducing the probability of corrosion of the pipe body 1 due to moisture. The connecting half ring 44 is sleeved on the top of the outer side of the pipe body 1, and its end is fixedly connected to the top of the rainproof sleeve 41, which strengthens the structural connection stability of the upper rainproof component 3 and the lower rainproof component 4. Because there is a gap between the upper surface of the pipe body 1 and the rain cover 31, rainwater will inevitably drip onto the upper surface of the pipe body 1 when it is raining at an angle or when it is windy. Since the friction coefficient between the wiper assembly 5 and the upper rain cover 3 and the lower rain cover 4 is low, it is easy to drive. Under the scouring of rainwater or the push of wind, the wiper assembly 5 can start cleaning. The ball bearing 54 on the movable support rod 53 at the top of the wiper half-set 51 will roll along the sliding groove 33 at the bottom of the rain cover 31, driving the wiper half-set 51 to move back and forth along the surface of the pipe body 1. During this process, the wiper blade 52 simultaneously wipes and cleans the rainwater on the upper surface of the pipe body 1 to prevent rainwater residue, ensure the cleanliness of the upper surface of the pipe body 1, and reduce the impact of long-term dirt accumulation on the service life of the pipe body 1. The entire process forms a protective closed loop of "all-round rain protection - efficient water diversion - real-time cleaning" through the top rainproof component 3, the bottom protection and drainage of the lower rainproof component 4, and the surface cleaning of the wiper component 5, which effectively improves the protective performance and service life of PE power pipes in humid environments.
