The power communication cable is the foundation for developing power engineering, and the current arrangement mode of the communication cable mainly comprises overhead and buried modes. For the power engineering of the cross-sea area, the communication cables can only be arranged in an overhead mode, but the weather of wind and rain on the sea surface is more, the cables are seriously damaged by corrosion, and the conventional bridge cannot be used, so that a special bridge is required to be designed to meet the arrangement of the communication cables on the sea surface.
Disclosure of Invention
The utility model aims to provide a high-span power bridge, which realizes the cross-sea arrangement of communication cables, resists the erosion of sea surface wind and rain and is durable in use.
The technical scheme adopted by the utility model is that the high-span power bridge comprises a bridge main body with a rectangular frame structure, wherein a plurality of cable brackets are horizontally arranged inwards at two sides of the bridge main body, and a rain shelter is arranged above the bridge main body.
Preferably, a supporting beam is fixedly arranged between the top end of the bridge body and the rain shelter, and the supporting beams are uniformly arranged at a preset distance along the width of the bridge body.
Preferably, the support beam is made of I-steel or section steel.
Preferably, the bridge body comprises a bottom cross beam, a top cross beam, longitudinal beams and stand columns, wherein the two bottom cross beams and the two top cross beams are arranged in parallel at intervals of a preset distance, the longitudinal beams are arranged between the two bottom cross beams or the two top cross beams in parallel at intervals, and the stand columns are fixedly arranged between the top cross beams and the bottom cross beams which are positioned on the same plane.
Preferably, diagonal braces are arranged between the upright posts, and connecting lines between the adjacent diagonal braces and the top cross beam or the bottom cross beam are triangular.
Preferably, reinforcing ribs are arranged between the adjacent longitudinal beams in a crossing manner.
The bridge main body has the beneficial effects that the bridge main body is formed by connecting and assembling profile steel or I-steel as a base material, has a rectangular frame structure, reduces wind damage on the sea surface while ensuring the structural strength, and is beneficial to heat dissipation; a plurality of cable brackets are arranged in the bridge main body, so that a plurality of layers of cables can be stably arranged, the trend is clear, and the installation and the maintenance are convenient; in addition, solve the problem of rainwater erosion through setting up the canopy, wherein, set up a supporting beam between canopy and the crane span structure main part, effectively increase the area of connection of canopy and crane span structure main part, improve the connection steadiness, reduce the sea wind influence.
