The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] See Figures 1-3 A preferred embodiment of the present invention provides an auxiliary device for laying underground cables that facilitates maintenance, comprising: a cable trench body 1, a first cover plate 2, an observation window assembly 3, and a maintenance cover plate 4.

[0036] The cable trench body 1 is for underground burial. Depending on the intended use of the cable trench, the cable trench body 1 has a hollow accommodating cavity 101, wherein the cross-sectional shape of the accommodating cavity 101 is preferably rectangular. The accommodating cavity 101 is used to accommodate and protect the cables laid therein. According to the conventional requirements of underground cable laying, an inspection port 102 is provided at the top of the cable trench body 1. The inspection port 102 penetrates the top structure of the cable trench body 1, providing a working passage to the interior of the accommodating cavity 101.

[0037] The first cover plate 2 is installed and covers the top of the cable trench body 1, sealing the top opening of the accommodating cavity 101. The first cover plate 2, as the main covering element, is sized to cover most of the continuous area of ​​the cable trench body 1, forming the main protective barrier.

[0038] The observation window assembly 3 is installed above the cable trench body 1 and seals the receiving cavity 101. The length of the observation window assembly 3 is much smaller than that of the first cover plate 2. This relatively small size allows the observation window to be discretely distributed at key monitoring points extending along a predetermined route within the cable trench body 1. The observation window assembly 3 includes a transparent observation window 301, which allows maintenance personnel to observe the cable condition within the receiving cavity 101. Preferably, the transparent observation window 301 is made of high-strength transparent glass.

[0039] The inspection cover 4 is installed above the cable trench body 1 and seals the accommodating cavity 101. The inspection cover 4 covers the inspection port 102. The size of the inspection cover 4 matches that of a single inspection port 102, and its length is much smaller than that of the first cover 2. It can be understood that the miniaturized design of the inspection cover 4 facilitates manual opening or closing operations.

[0040] When the cable is operating normally, the first cover plate 2, the observation window assembly 3, and the maintenance cover plate 4 are all in a closed and sealed state. During routine inspections, maintenance personnel can directly observe the real-time condition of the cable inside the accommodating cavity 101 of the cable trench body 1 through the transparent observation window 301 of the observation window assembly 3, such as whether the cable sheath is damaged, whether the joints are abnormal, or whether there is water accumulation or foreign object intrusion, thus enabling preliminary fault diagnosis. If an abnormality is found or maintenance is required, the nearest maintenance cover plate 4 is opened, and work is carried out through the maintenance port 102. After the work is completed, the maintenance cover plate 4 is closed to restore the seal.

[0041] The cable trench body 1 is designed for underground burial and includes a receiving cavity 101 for housing the cable, thus providing concealed protection. The cable trench body 1 also features an inspection port 102, allowing for pre-planned maintenance access and providing a location for maintenance personnel. A first cover plate 2 is installed above the cable trench body 1 and seals the receiving cavity 101, creating a continuous, sealed environment to prevent soil and water from entering the trench and ensuring long-term dry and stable cable operation. An observation window assembly 3 is installed above the cable trench body 1 and seals the receiving cavity 101, preventing external contaminants from seeping in and ensuring a sealed environment. The observation window assembly 3 includes a transparent observation window 301, allowing maintenance personnel to observe the cable condition within the receiving cavity 101. This eliminates the need for repeatedly opening the large cover plate to inspect the cable, enabling direct assessment of aging, damage, water accumulation, and other abnormal conditions, significantly improving operational efficiency. The inspection cover 4 is installed above the cable trench body 1 and seals the accommodating cavity 101, so that the inspection port 102 is in a closed state when no maintenance is being performed. Together with the first cover 2 and the observation window assembly 3, it forms a fully enclosed protective system to ensure that the underground cable is isolated from the external environment. Because the inspection cover 4 covers the inspection port 102, the target cable can be directly accessed by opening the inspection cover 4, making maintenance operations more precise.

[0042] Preferably, the observation window assembly 3 further includes a support frame 302 and a movable cover plate 303. The support frame 302 is installed above the cable trench body 1 and supported by the cable trench body 1. Preferably, the support frame 302 has four legs welded to its bottom, and the four legs are connected to the leg holes on the upper part of the cable trench body 1 by bolts. The transparent observation window 301 is installed inside the support frame 302 and supported by the support frame 302. Preferably, the support frame 302 has a limiting groove machined on its inner side, and the transparent observation window 301 is embedded in the limiting groove after its edge is wrapped with a silicone cushioning pad. The movable cover plate 303 covers the transparent observation window 301 and can cover or move away from the transparent observation window 301.

[0043] Preferably, the observation window assembly 3 further includes a mesh support 304, wherein the material of the mesh support 304 is preferably stainless steel woven mesh. The mesh support 304 is connected to and supported by the support frame 302. Preferably, the support frame 302 has an annular mounting groove machined inside, and the outer edge of the mesh support 304 is wrapped with a silicone frame and embedded in the mounting groove. The movable cover plate 303, the mesh support 304, and the transparent observation window 301 are stacked sequentially from the outside to the inside along the cable trench body 1. The stacking height of the movable cover plate 303, the mesh support 304, and the transparent observation window 301 is consistent with the height of the first cover plate 2 and the maintenance cover plate 4, so that the road surface remains flat.

[0044] Preferably, the movable cover plate 303 is hinged to the edge of the support frame 302. The support frame 302 is machined with a hinge mounting groove, and a through hole is drilled at the bottom of the groove, which connects to the through hole on the side of the movable cover plate 303 via a hinge.

[0045] Preferably, the inspection cover 4 is fixed to the cable trench body 1 by bolts. Specifically, four pre-embedded nuts are spaced circumferentially at the edge of the cable trench body 1 corresponding to the inspection port 102, and through holes matching the pre-embedded nuts are opened at corresponding positions on the edge of the inspection cover 4, allowing the bolts to pass through smoothly.

[0046] Preferably, there are at least two of each of the first cover plate 2, observation window assembly 3, and maintenance cover plate 4, wherein the number of the first cover plate 2, observation window assembly 3, and maintenance cover plate 4 is determined according to the length range of the cable trench body 1. Multiple first cover plates 2, multiple observation window assemblies 3, and multiple maintenance cover plates 4 are sequentially and alternately connected along the extension direction of the cable trench body 1. Adjacent components of the first cover plate 2, observation window assembly 3, and maintenance cover plate 4 are connected by overlapping edges to ensure a flat and continuously sealed top surface.

[0047] Preferably, the movable cover 303 is made of lightweight aluminum alloy. It is understood that lightweight aluminum alloy can reduce the weight of the movable cover 303 while ensuring structural strength, making it easier and more convenient for maintenance personnel to open and close. The movable cover 303 is provided with a handle 305, which is used to open and close the movable cover 303. The handle 305 is preferably made of stainless steel and is U-shaped. Both ends of the handle 305 are bolted to the side of the movable cover 303 away from the hinge edge.

[0048] Preferably, the underground cable laying auxiliary device for easy maintenance further includes multiple cable support devices 5, which are arranged sequentially and at intervals on the inner wall of the cable trench body 1 along the extension direction of the cable trench body 1. Preferably, the cable support devices 5 are fixed to the inner wall of the cable trench body 1 with bolts. This connection method facilitates secure installation and subsequent maintenance or replacement of the cable support devices 5.

[0049] Preferably, the cable support device 5 includes a support member 501 and a separator 502. The support member 501 is preferably rectangular in shape, providing stronger bending resistance and the ability to support the weight of multiple cables. The support member 501 is detachably connected to the cable trench body 1, preferably using a plug-in structure. The separator 502 is detachably connected to the support member 501, preferably using a snap-fit ​​structure, allowing installation and disassembly to be completed in just a few seconds without any tools.

[0050] Preferably, the separator 502 includes an arc-shaped segment 503 and a straight segment 504, the arc-shaped segment 503 being used to wrap around the cable. The opening angle of the arc-shaped segment 503 is preferably designed to facilitate cable insertion while providing sufficient wrapping force. The end of the straight segment 504 away from the arc-shaped segment 503 is detachably connected to the support member 501. Preferably, the detachable connection between the end of the straight segment 504 away from the arc-shaped segment 503 and the support member 501 is achieved using a pin-type snap-fit ​​structure.
