Description

Technical Field

[0001] This utility model relates to the technical field of cable trench covers, specifically to a stainless steel mesh composite cable trench cover. Background Technology

[0002] Cable trench covers are protective facilities placed over cable trenches to protect cables inside from external forces, water, debris, and other damage. They are widely used in cable laying areas in municipal, power, and factory settings.

[0003] Utility model patent CN219471011U discloses a cable trench cover, mainly comprising a cable trench, a cover plate, a connecting block, and a rotation positioning assembly. The cable trench has a cover plate on top, and a connecting block is fixed to the inner side of the cover plate. A groove is formed in the middle of the cover plate, and a through hole is formed in the middle of the connecting block. The bottom of the through hole connects to a slot, and both ends of the slot communicate with the outside of the connecting block. A flip cover is hinged to the top of the groove, and a notch is formed on the upper surface of the flip cover. Slots are formed on both sides of the top of the cable trench, and insert blocks are fixed on both sides of the bottom of the cover plate, inserting into the slots. The rotation positioning assembly is disposed between the cover plate, the connecting block, and the cable trench. This utility model can prevent the cover plate from shifting relative to the cable trench, and the cover plate is easy to position and install, facilitating worker operation.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects: Existing cable trench covers are made of a single material. When the covers are in complex environments, they not only suffer from defects such as metals being prone to rust and corrosion, pure fiberglass having insufficient load-bearing or impact resistance, and plastic and wood having insufficient aging resistance or strength, but also ordinary materials are prone to corrosion, deformation, or loose connections. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a stainless steel mesh composite cable trench cover, which can effectively solve the problem that the cover is easily damaged by environmental factors when it is in a complex environment.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a stainless steel mesh composite cable trench cover, including a galvanized angle steel frame, a stainless steel mesh, a fiberglass mesh, stainless steel pull rings, and stainless steel pressure plates. The stainless steel pressure plates connect the stainless steel mesh and the fiberglass mesh with bolts. The stainless steel mesh is located inside the galvanized angle steel frame. The stainless steel mesh and the galvanized angle steel frame are welded and fixed by argon arc welding. The stainless steel pull rings are installed on both sides of the top of the fiberglass mesh. Insertion assembly components are provided on both sides of the top inner wall of the galvanized angle steel frame, and disassembly and protection components are provided on the outer side of the top of the galvanized angle steel frame.

[0008] The above scheme uses a galvanized angle steel outer frame as the main frame, and an internal stainless steel mesh is fixed by argon arc welding to enhance structural strength and corrosion resistance. Stainless steel pull rings facilitate the handling of the cover plate. The plug-in assembly components and the disassembly and protection components respectively enable the rapid installation and fixing of the fiberglass mesh and the safe disassembly and protection.

[0009] Furthermore, the plug-in assembly includes a fixing groove, a connecting plate installed on the outer side of the inner wall of the fixing groove, a spring on the inner side of the connecting plate, a slider installed on the other end of the spring, a plug-in plate installed on the inner side of the slider, and the inner side of the plug-in plate plugging into and connecting with the outer side of the fiberglass mesh.

[0010] In the above scheme, in the plug-in assembly, the connecting plate in the fixing groove is connected to a spring. The spring pushes the slider to drive the plug-in plate, so that the inner side of the plug-in plate is plugged into the outer side of the fiberglass mesh. The spring force is used to achieve elastic plug-in fixation between the fiberglass mesh and the galvanized angle steel outer frame, which is convenient for assembly.

[0011] Furthermore, the disassembly and protection assembly includes a connecting groove, the bottom of which is connected to a fixed groove. An inclined plate is slidably connected inside the connecting groove, and a strong magnetic block that can be inserted after the inclined plate is removed is slidably connected inside the connecting groove. The strong magnetic block is magnetically connected to the slider.

[0012] With the above solution, during the disassembly of the protective assembly, the connecting groove connects to the fixed groove, the inclined plate can slide in the connecting groove, and the strong magnetic block is inserted into the connecting groove and magnetically connected to the slider when the inclined plate is moved out. The strong magnetic attraction pulls the slider to compress the spring, so that the plug-in plate is separated from the fiberglass mesh, realizing convenient disassembly without tools. At the same time, the inclined plate can prevent debris from entering the fixed groove.

[0013] Furthermore, a support block is installed on the inner side of the inner wall of the galvanized angle steel outer frame. Several support blocks are provided and are arranged at equal intervals. The top of the support block is arc-shaped. A support plate is installed at the bottom of the fiberglass mesh. The bottom of the support plate is inserted and connected to the top of the support block.

[0014] With the above scheme, the support blocks on the inner wall of the galvanized angle steel outer frame are evenly distributed and have an arc-shaped top. The support plate at the bottom of the fiberglass mesh is inserted into the top of the support block. The arc-shaped support surface increases the contact area. Several support blocks jointly support the fiberglass mesh, improving the stability and uniformity of the load when the cover plate is under load.

[0015] Furthermore, a cover plate is inserted into the top of the connecting groove, which is installed when the strong magnetic block is removed, and a sealing block is installed at the bottom of the cover.

[0016] With the above solution, a cover plate is inserted at the top of the connecting groove when the strong magnetic block is removed. The sealing block at the bottom of the cover plate can seal the opening at the top of the connecting groove, preventing water and debris from entering the interior of the connecting groove.

[0017] Furthermore, a drainage hole is provided on the outer side of the galvanized angle steel frame, the inner side of the drainage hole is connected to the outer side of the connecting groove, and the inclined plate is located inside the drainage hole.

[0018] With the above solution, the drainage hole on the outside of the galvanized angle steel frame is connected to the outside of the connecting groove, and the inclined plate is located inside the drainage hole. When water enters the connecting groove, the inclined plate guides the water flow to be discharged along the drainage hole, avoiding water accumulation and corrosion of internal parts. The inclined design also reduces the retention of debris.

[0019] Furthermore, a sealing plate is installed on the outer side of the slider, and an elastic block is installed on the top of the support block.

[0020] Through the above solution, the sealing plate on the outside of the slider can seal the opening of the fixing groove, preventing water and dust from entering and affecting the performance of parts such as springs. The elastic block on the top of the support block can buffer the impact force when the fiberglass mesh is under load, reduce rigid contact wear, and improve connection stability and service life.

[0021] Furthermore, a movable block is installed on the top of the cover plate, and a triangular block is installed between the support blocks. The triangular block is installed on the inner side of the inner wall of the galvanized angle steel outer frame.

[0022] With the above solution, the movable block at the top of the cover strip facilitates the disassembly and assembly of the cover plate, and the triangular blocks between the support blocks are installed on the inner wall of the galvanized angle steel outer frame. The triangular structure enhances the connection strength between the support blocks, improves the overall frame's resistance to deformation, and ensures that all components work together stably.

[0023] Beneficial effects

[0024] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0025] I. This utility model incorporates components such as a galvanized angle steel frame, stainless steel mesh, and fiberglass mesh. The galvanized angle steel frame serves as the main framework, the stainless steel mesh is welded and fixed inside to enhance structural strength and corrosion resistance, and the fiberglass mesh covers the surface. This synergistic relationship between the three materials allows them to complement each other. The metal frame provides impact resistance, the stainless steel mesh provides corrosion resistance, and the fiberglass is lightweight and weather-resistant. As a result, this device can solve the problems of easy corrosion and insufficient load-bearing capacity of a single material in complex environments by combining composite materials, thereby improving the overall performance of the cover plate.

[0026] II. This utility model, by setting a fixing groove, spring, slider, and plug-in plate in the plug-in assembly component, and a connecting groove, strong magnetic block, and inclined plate in the disassembly and protection component, etc., achieves the effect of convenient installation and maintenance and structural protection through the spring pushing the plug-in plate to be plugged and fixed with the fiberglass mesh, and the strong magnetic block magnetically attracting the slider to disengage the plug-in plate. This allows the cover plate to be quickly installed by elastic plugging and disassembled without tools by magnetic attraction. At the same time, the inclined plate prevents debris from entering the fixing groove. Thus, this device can achieve the effect of convenient installation and maintenance and structural protection through modular component design, and avoid loosening of the connection.

[0027] Third, by setting up components such as support blocks, elastic blocks, and triangular blocks, the support blocks provide equidistant arc support for the bottom support plate of the fiberglass mesh, the elastic blocks buffer the impact of the load, and the triangular blocks enhance the connection strength between the support blocks. This makes the force evenly distributed when bearing load, reduces rigid wear, and improves the stability of the frame. Thus, this device can improve the load-bearing capacity and service life of the cover plate through the design of multiple support structures, and adapt to high-frequency load scenarios.

[0038] Support blocks 7 are installed on the inner side of the inner wall of the galvanized angle steel outer frame 1. Several support blocks 7 are arranged at equal intervals, and the top of the support blocks 7 is arc-shaped. A support plate 8 is installed at the bottom of the fiberglass mesh 3, and the bottom of the support plate 8 is inserted into the top of the support block 7. A cover strip 9, which is installed when the strong magnetic block 63 is removed, is inserted into the top of the connecting groove 61. A sealing block 10 is installed at the bottom of the cover strip 9. A drainage hole 11 is opened on the outer side of the galvanized angle steel outer frame 1, and the inner side of the drainage hole 11 is connected to the connecting groove 61. The outer side is connected, the inclined plate 62 is located inside the drain hole 11, the outer side of the slider 54 is equipped with a sealing plate 12, the top of the support block 7 is equipped with an elastic block 13, the top of the cover strip 9 is equipped with a moving block 14, the support blocks 7 are equipped with a triangular block 15, the triangular block 15 is installed on the inner side of the inner wall of the galvanized angle steel outer frame 1, the magnetic induction intensity of the strong magnetic block 63 is ≥500mT, the magnetic attraction force with the slider 54 is ≥50N, the inclined plate 62 has an inclination angle of 30°-45°, and guides the accumulated water to be discharged through the drain hole 11.

[0039] Working principle: During assembly, the stainless steel mesh 2 is first fixed to the inside of the galvanized angle steel outer frame 1 by argon arc welding to form a rigid skeleton. Then, the strong magnetic block 63 is moved into the inside of the connecting groove 61. Its magnetic attraction pulls the slider 54 outward, compressing the spring 53 and driving the plug-in plate 55. Then, the fiberglass mesh 3 is placed inside the outer frame. When the fiberglass mesh 3 is in place, the strong magnetic block 63 is removed. The spring 53 pushes the slider 54 to reset, so that the inner side of the plug-in plate 55 is precisely plugged into the outer side of the mesh, achieving rapid fixation. At the same time, the bottom support plate 8 of the mesh is inserted into the top of the arc-shaped support blocks 7 that are evenly distributed on the inner wall of the outer frame. The elastic block 13 buffers the contact impact, and the triangular block 15 enhances the stability of the support structure. Finally, the overall assembly of the composite cover plate is completed.

[0040] The galvanized angle steel outer frame 1 serves as a rigid skeleton, providing load-bearing support. Its galvanized layer resists external corrosion. The stainless steel mesh 2 is welded to the inside of the outer frame and forms an integral frame through argon arc welding, enhancing impact resistance and structural strength. At the same time, the stainless steel material is corrosion resistant, avoiding the rusting problem of traditional metals. The fiberglass mesh 3 covers the top of the outer frame and is connected to the support blocks 7 on the inner wall of the outer frame through the bottom support plate 8, forming a composite structure. The support blocks 7 are evenly distributed and have an arc-shaped design at the top, increasing the contact area with the fiberglass mesh 3 and evenly distributing the load-bearing pressure. The elastic block 13 is installed on the top of the support block 7 to buffer the impact force when the mesh is under load, reducing rigid contact wear. The triangular block 15 connects the support block 7, using the stability of the triangle to enhance the frame's resistance to deformation and ensure the overall structural stability.

[0041] When the overall structure needs maintenance, it can be easily lifted by the stainless steel pull ring 4 to separate the overall structure from the cable trench, making it convenient for users to perform maintenance and repairs inside the cable trench.

[0042] When the fiberglass mesh 3 needs to be disassembled for maintenance or replaced due to damage, first remove the cover strip 9 at the top of the connecting groove 61 by moving block 14, take out the inclined plate 62 to expose the installation position of the strong magnetic block 63, insert the strong magnetic block 63 into the connecting groove 61, its magnetic attraction pulls the slider 54 to move outward, compresses the spring 53 and drives the plug plate 55 to disengage from the fiberglass mesh 3. At this time, the fiberglass mesh 3 loses its limit and can be easily lifted by the stainless steel pull ring 4 to achieve quick disassembly. The protective structure, the dustproof and debris-proof inclined plate 62, normally covers the interface between the connecting groove 61 and the drain hole 11 to prevent debris from entering the fixed groove 51. After disassembly, reinsert the inclined plate 62 and cover it with the cover strip 9. The sealing block 10 at the bottom of the cover strip 9 seals the opening of the connecting groove 61 to prevent water and dust from entering. The strong magnetic block 63 is not inserted into the inside of the connecting groove 61 during daily use. Users only need to keep a few strong magnetic blocks 63 on hand and use them normally when disassembly and assembly are required.

[0043] When water seeps into the connecting groove 61 through the gap in the cover plate, the inclined plate 62 guides the water flow to the outside along the drain hole 11. The inclined plate 62’s slope design avoids water accumulation and stagnation, while the water flow force reduces the deposition of debris. The drain hole 11 is connected to the connecting groove 61 to form a complete drainage path, preventing internal parts from being corroded. The sealing plate 12 on the outside of the slider 54 covers the opening of the fixing groove 51 to prevent water and dust from entering and affecting the performance of the spring 53. The sealing block 10 at the top of the connecting groove 61 cooperates with the cover strip 9 to further improve the overall sealing performance.

[0044] The galvanized angle steel frame 1 provides high-strength support, and the galvanized layer on the surface enhances its corrosion resistance. The stainless steel mesh 2 is welded inside the frame to improve the overall structural strength and resist corrosive environments such as acids and alkalis. The fiberglass mesh 3 covers the surface and has lightweight, weather-resistant, and insulating properties, preventing direct metal exposure that could lead to rust. It also reduces the overall weight of the cover plate for easy handling. The stainless steel pull ring 4 is welded to the top of the fiberglass mesh 3 for easy manual or mechanical lifting, improving operational convenience.

[0045] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
