Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipelines, and more specifically, to a power cable pipe. Background Art
[0002] With the development of social modernization, communication has become increasingly important. To ensure timely and smooth communication, the laying of cables has also become increasingly important. Currently, cables are mainly buried underground. When cables are buried underground, they are easily squeezed by soil, and when the cable outer skin is damaged, it is vulnerable to the influence of underground seepage water, resulting in easy damage to the cables. Once damaged, it is very difficult to repair or replace the cables directly buried underground. At this time, it is necessary to pre-place the cables in the power cable pipes and then bury them underground. A power cable pipe is a pipe used to protect cables from the external environment, usually used for burying cables underground to ensure the safe and stable operation of the cables. To save costs, power cable pipes are generally made of materials such as PVE. Existing power cable pipes for underground burial have the problem of insufficient support strength and being easily bent by backfill soil. Once the pipeline deforms, it will exert pressure on the internal cable wires, and the problem of the cable wires being crushed is likely to occur. Summary of the Utility Model

[0037] Embodiment
[0038] Combined with Figures 1 - 5 , the present utility model provides a power cable pipe, which divides the channel surrounded by the pipe wall 23 into two parts, a rectangular channel 27 provided at the lower part and a trapezoidal channel 26 provided at the upper part. When the pipe is buried underground, the two side walls of the lower rectangular channel 27 are straight walls, which can provide a sufficient large supporting force for the upper trapezoidal channel 26 to ensure that the lower rectangular channel 27 will not be bent and deformed. The short side of the upper trapezoidal channel 26 is located at the upper part, and the two inclined sides are inclined, changing the pressure of the backfill soil above from all downward to part downward and part to the side, thereby reducing the pressure on the pipe wall 23 and reducing the possibility of deformation of the pipe wall 23.
[0039] Specifically, referring to Figure 1 and Figure 4 , a power cable pipe of this embodiment includes an interface part 1 and a pipe body part 2 connected together. In this embodiment, the interface part 1 and the pipe body part 2 are integrally formed. Alternatively, according to needs, the interface part 1 and the pipe body part 2 can be connected together by means of bonding, welding, fusion connection, etc., as long as they are sealed and watertight after connection. In this embodiment, the interface part 1 includes the open mouth 11 directly connected to the pipe body part 2. The open mouth 11 is thinner than the pipe body part 2, and the outer wall of the open mouth 11 is aligned with the outer wall of the pipe body part 2. The part of the pipe body part 2 extending inward from the open mouth 11 forms a step surface 12. When two pipes are connected together, the step surface 12 can act as a limiting part to avoid excessive insertion of the pipe and resulting in pipe damage.
[0040] In this embodiment, the pipe body part 2 includes a pipe wall 23, and the pipe wall 23 encloses a channel; the channel includes a trapezoidal channel 26 and a rectangular channel 27, the trapezoidal channel 26 and the rectangular channel 27 are connected, and are separated by an imaginary line 25; the short side of the trapezoidal channel 26 is arranged away from the rectangular channel 27. When the power cable pipe is buried underground, the trapezoidal channel 26 is located in the upper part, and the rectangular channel 27 is located in the lower part. They can be directly connected in the middle for placing cable lines, or a grid structure can be set for placing cable lines.
[0041] In this embodiment, the trapezoidal channel 26 includes a third inner wall 233 and a fourth inner wall 234. The two third inner walls 233 are inclined at both ends of the fourth inner wall 234. The two third inner walls 233, the fourth inner wall 234 and the imaginary line 25 enclose the trapezoidal channel 26. The cross-section of the trapezoidal channel 26 is an isosceles trapezoid, and the range of the angle α between the third inner wall 233 and the imaginary line 25 is 15 degrees - 85 degrees. In this embodiment, when the angle α is 45 degrees, the structure of the upper trapezoidal channel 26 is the most stable, which can ensure that the pipe wall 23 does not deform to the greatest extent. In this embodiment, the upper trapezoidal channel 26 is an isosceles trapezoid, so that the lateral forces on the two upper hypotenuses are equal and the force directions are opposite, thereby canceling the lateral forces and further reducing the possibility of deformation of the pipe wall 23.
[0042] In this embodiment, the rectangular channel 27 includes a first inner wall 231 and a second inner wall 232. The two second inner walls 232 are vertically arranged at both ends of the first inner wall 231. The two second inner walls 232, the first inner wall 231 and the imaginary line 25 enclose the rectangular channel 27. The cross-section of the rectangular channel 27 is a rectangle, and the length of the second inner wall 232 is less than the length of the first inner wall 231. In this embodiment, the lower rectangular channel 27 is a rectangle, and the two side walls are short sides. Without changing the area, the length of the short sides is reduced, further reducing the possibility of deformation of the two side walls. In this embodiment, the flat bottom makes the pipe easy to adhere to the ground or the surface of the structure, facilitating the backfilling and compaction at the bottom, reducing deformation, and protecting the inner cable. In this embodiment, by expanding the length of the long side, the cables are separated when arranging, and the cables will not form superposition or crossing in the pipe, which is convenient for later maintenance and replacement; the cables are evenly arranged in the pipe without superposition, which is convenient for heat dissipation, reduces power consumption, reduces the aging of the cables, and prolongs the service life of the cables.
[0043] Combined with Figure 2, the open end 11 in this embodiment includes a first interface plate 111, a second interface plate 113, a third interface plate 115, and a fourth interface plate 117. The first interface plate 111, the second interface plate 113, the third interface plate 115, and the fourth interface plate 117 are connected to enclose a connection channel, and the connection channel has the same shape as the channel formed by the pipe wall 23. A first transition plate 112 is provided at the connection between the first interface plate 111 and the second interface plate 113, a second transition plate 114 is provided at the connection between the second interface plate 113 and the third interface plate 115, and a third transition plate 116 is provided at the connection between the third interface plate 115 and the fourth interface plate 117. The first transition plate 112, the second transition plate 114, and the third transition plate 116 are all arc-shaped structures. In this embodiment, the open end 11 is set thinner than the pipe wall 23, which is convenient for the installation of two sections of power cable pipes. At the same time, arc-shaped transition plates are provided at the joints of the interface plates of the open end 11, which can accommodate the corrugated structure 21 provided on the outer periphery of the pipe wall 23 and avoid generating gaps. After being blocked at both ends, it can prevent rainwater from seeping in and prevent small animals, etc. from entering and damaging the cables.
[0044] Combined with Figure 3 and Figure 5 , in this embodiment, a corrugated structure 21 is provided on the outer periphery of the outer wall of the pipe wall 23, and the corrugated structures 21 are arranged at intervals. The corrugated structures 21 are all arc-shaped structures at the corners. A gap 22 is formed at the interval of the corrugated structures 21, and a reinforcing rib 24 is provided on the outer wall of the pipe wall 23 at each gap 22 to improve the strength of the corrugated pipe. A corrugated groove 211 is also provided on the corrugated structure 21, so that the corrugated structure 21 forms a double wave, further strengthening the strength of the pipe.
[0045] The above schematically describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments to this technical solution without creative work without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
