Description

Technical Field

[0001] The utility model relates to the technical field of cable trench covers, in particular to a waterproof cable trench cover. Background Art

[0002] A cable cover is a protective device used to cover a cable trench or cable trough. Cable trench covers are usually made of materials such as metal, plastic, and concrete. They have strong load-bearing capacity and durability, can prevent people from accidentally falling, vehicles from running over them, and protect cables from damage by the external environment. The design of cable trench covers mainly considers load-bearing capacity, anti-slip performance, waterproofness, durability, and aesthetic appearance to ensure that they are suitable for different use environments. In some cases, cable trench covers are also specially marked, such as indicating "cables below" or drawing electricity icons to remind people of the location of the cables. Cable trench covers are an important part of urban infrastructure construction and play a key role in maintaining the normal operation of power and communication systems.

[0003] The existing cable trench cover has a simple structure and does not have a waterproof function. Since the cable trench is often in an open-air environment, it is inevitable that rainwater or accumulated water will enter the cable trench along the gaps between the covers, thus posing a hidden danger to the safety of the cables. For example, the utility model patent with application number 202320180027.8 discloses a cable trench cover, including a first cover and a second cover; the first cover and the second cover are alternately placed on the steps on both sides of the cable trench along the front and rear direction of the cable trench; the vertical cross-sections of the first cover and the second cover in the front and rear direction of the cable trench are both trapezoidal, and the bottom surfaces of the first cover and the second cover are in contact with the steps on both sides of the cable trench.

[0004] In the technical solution of the above patent, although the waist surfaces of adjacent cover plates fit in contact, the force of the first cover plate or the second cover plate can be transmitted to the surrounding adjacent cover plates through the contact surface, dispersing the force and improving the compressive strength of the cable trench cover plate. However, when laying, there is a gap between the adjacent first cover plate and the second cover plate, which cannot prevent rainwater or accumulated water from entering the cable trench along the gap between the cover plates.

[0005] Therefore, it is necessary to develop a waterproof cable trench cover for the above-mentioned defects. Utility Model Content

[0006] The utility model aims to provide a waterproof cable trench cover plate, which can prevent rainwater or accumulated water from entering the cable trench along the gaps between the cover plates, and is easy to disassemble and assemble, thereby facilitating the inspection and maintenance of the cable trench.

[0008] The utility model discloses a waterproof cable trench cover plate, which is horizontally buckled on the top opening of the cable trench body, and comprises a plurality of first cover plates and a second cover plate which are laid at intervals from each other, wherein the left and right ends of the top surface of the first cover plate are both concavely formed with a first corrugated section, and the left and right ends of the bottom surface of the second cover plate are both concavely formed with a second corrugated section which overlaps with the first corrugated section; the top surfaces of the first cover plate and the second cover plate are in the same horizontal plane.

[0009] Furthermore, wing plates are extended at the left and right ends of the top surface of the second cover plate; wing plate yielding platforms are provided on the left and right sides of the top surface of the first cover plate near the first corrugated section, the wing plates are pressed against the wing plate yielding platforms, and the wing plate yielding platforms are provided with guide grooves, which are opened along the length direction of the first cover plate.

[0010] Furthermore, the guide groove is located near the joint between the wing plate and the top surface of the wing plate yielding platform.

[0011] Furthermore, a mounting platform is provided at the top of the side wall of the cable trench body, a card slot is provided on the top surface of the mounting platform, and blocks corresponding to the card slot are provided at the front and rear ends of the first cover plate and the second cover plate, and the first cover plate and the second cover plate are connected to the card slot of the mounting platform through the card blocks.

[0012] Furthermore, baffles are vertically arranged at the front and rear ends of the first cover plate and the second cover plate, and the baffles are in contact with the outer wall of the mounting platform.

[0013] Furthermore, the top surfaces of the first cover plate and the second cover plate are provided with anti-slip patterns consisting of a plurality of cross-shaped anti-slip protrusions.

[0014] Furthermore, a graphic or text identification area is provided in the middle of the top surfaces of the first cover plate and the second cover plate.

[0015] Furthermore, the first cover plate and the second cover plate are provided with hidden handles at the front and rear ends of the top surfaces, respectively.

[0016] Compared with the prior art, the beneficial technical effects of the utility model are:

[0017] The utility model arranges the first corrugated section and the second corrugated section on the first cover plate and the second cover plate respectively. Through the cooperation of the first corrugated section and the second corrugated section, the connection between the adjacent first cover plates and the second cover plates is tighter, which can prevent rainwater or accumulated water from entering the cable trench, and has a good waterproof effect. At the same time, by arranging the second cover plate on the two first cover plates, and arranging hidden handles on the first cover plate and the second cover plate, when the cable trench needs to be inspected, it is only necessary to lift any first cover plate by the handle.

[0018] In addition, by providing the wing plate and the guide groove, the accumulated water on the surface of the first cover plate and the second cover plate can be guided to the outside of the cable trench through the guide groove to prevent it from flowing into the cable trench through the gap at the connection between the cover plates. A mounting platform is provided on the side wall of the cable trench, and a card slot is provided on the mounting platform. The card blocks on the first cover plate and the second cover plate are connected to the card slot and provided on the baffle plate, so as to prevent water from seeping into the connection between the first cover plate and the second cover plate and the cable trench, thereby improving the waterproof effect.
