Description

Technical Field

[0001] The utility model belongs to the technical field of electric power equipment, and in particular relates to an electric power cover plate. Background Art

[0002] In traditional power transmission and distribution systems, cable lines are usually placed in underground cable trenches to protect the cables from external environmental influences and human damage. In these systems, power covers play a vital role. They cover the top of the cable trench and provide a solid protective layer for the cables. These covers are generally made of metal, concrete or composite materials, and are designed to be supported by the edges of the cable trench at both ends. However, there are some defects in the power cover structure in the prior art. When the power cover on the cable trench is subjected to uneven forces, especially when the middle part of the cover is frequently or continuously subjected to excessive forces, such as when large machinery passes by or is affected by natural disasters, the power cover may be deformed. This deformation will not only reduce the load-bearing capacity of the cover itself, but may also cause the sealing between the cover and the cable trench to be damaged, thereby exposing the cable to the external environment, increasing safety risks and maintenance costs.

[0003] Therefore, in order to improve the reliability and durability of the power cover, developing a power cover with higher bearing capacity, better mechanical property distribution and better deformation resistance is an urgent problem to be solved in the existing technology. Utility Model Content

[0004] The purpose of the utility model is to provide an electric cover plate with better bearing capacity in view of the above-mentioned technical problems.

[0005] In view of this, the utility model provides a power cover, characterized by comprising:

[0006] A cable frame, wherein the cable frame is hollow at the front and rear and has an upward opening;

[0007] A cover plate cover body, the cover plate cover body is erected above the cable frame, an empty slot is arranged at the bottom of the cover plate cover body, a support plate is arranged in the empty slot, the support plate extends along the length direction of the empty slot, the two ends of the support plate abut against the support structure extending from the bottom of the cover plate cover body, and the top of the support plate abuts against the top wall of the empty slot.

[0008] In the present technical solution, the cover body is erected on the cable frame, an empty groove is provided at the bottom of the cover body, a support plate is provided in the empty groove, the top of the support plate and the top of the empty groove are in contact with each other, the empty groove extends along the length direction of the cover body, the support plate extends along the direction of the empty groove, both ends of the support plate are supported by the support structure extending from the bottom of the cover body, when the middle part of the cover body is subjected to pressure, the support plate helps to disperse the pressure in the middle part of the cover body to both sides, effectively preventing the cover plate from being deformed or damaged due to excessive local force, so that the cover body has better bearing capacity.

[0009] In the above technical solution, further, support grooves are symmetrically arranged on the support arms of the cable frame, and the support grooves are used to place the cover plate cover body, and the cover plate cover body and the support grooves are in contact with each other.

[0010] In the above technical solution, further, the supporting structure is a fixing plate correspondingly arranged at both ends of the empty slot, the fixing plate extends downward and is vertically bent inward, and both ends of the fixing plate and the supporting plate abut against each other.

[0011] In this technical solution, the supporting end of the support plate can be firmly supported, and the two ends of the support plate can be fixedly connected to the fixing plate by fasteners such as bolts and screws, so as to avoid the support plate from vibrating when the pressure on the cover body is changed, thereby preventing the effect of sharing the force of the cover plate and the cover body.

[0012] In the above technical solution, further, the fixing plate abuts against the inner wall of the cable frame.

[0013] In this technical solution, the cover plate and cover body are stressed, the support plate disperses the pressure to both ends, and the fixing plate and the cable frame are against each other, which can further enhance the stress effect of the fixing plate and avoid fatigue damage caused by exceeding the strength limit of the material.

[0016] In the above technical solution, further, the top of the cover plate cover body is an arc-shaped protruding structure, and the cable frame support arm has an arc-shaped structure that is compatible with the curvature of the cover plate cover body.

[0017] In the present technical solution, the cover body is an arc-shaped raised structure, with the middle height gradually decreasing towards the support arms on both sides. In terms of bearing capacity, it helps to distribute the load applied thereon more evenly to the entire cover. This force distribution method can improve the overall bearing capacity of the cover. At the same time, when water or rain falls on the cover body, it can slide to both sides to ensure the dryness of the surface of the cover body. The cable frame support arm has an arc-shaped structure that matches the curvature of the cover body, which facilitates better drainage of rainwater and sewage, keeps the surface of the cover body dry, avoids liquid retention, and has a good anti-slip effect.

[0020] In the above technical solution, further, the anti-slip strips are wavy protrusions arranged at equal intervals.

[0021] In the present technical solution, the wave-shaped protrusions can form more friction points on the surface of the cover plate, which can more effectively increase the surface roughness, thereby improving the anti-slip performance, and also help guide water flow and reduce water accumulation.

[0022] In the above technical solution, further, a waterproof strip is provided between the cover plate cover and the support groove.

[0023] In this technical solution, the waterproof strip is an L-shaped structure made of waterproof rubber material, which can fully fit the cover body and the support groove to prevent rainwater and sewage from entering the cable frame and soaking the cables laid inside to cause damage.

[0024] The beneficial effects of the utility model are:

[0025] 1. The middle part of the cover body is under pressure, and the support plate helps to disperse the pressure in the middle part of the cover body to both sides, effectively preventing the cover from being deformed or damaged due to excessive local force, so that the cover body has better bearing capacity;

[0026] 2. The top of the cover body is an arc-shaped convex structure, and the cable frame support arm has an arc-shaped structure that matches the arc of the cover body, which helps to distribute the load applied thereon more evenly to the entire cover, facilitates better drainage of rainwater and sewage, keeps the surface of the cover body dry, avoids liquid retention, and has a good anti-slip effect;

[0027] 3. The anti-slip strips are equidistantly arranged wave-shaped protrusions. The wave-shaped protrusions can form more friction points on the surface of the cover plate, which can more effectively increase the surface roughness, thereby improving the anti-slip performance, and also help guide water flow and reduce water accumulation.
