Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic power generation, and in particular relates to a composite cable bridge. Background Art

[0002] After photovoltaic panels are installed, cables are usually loaded on a bridge frame to be fed into the power distribution cabinet and then transmitted to the substation. The traditional bridge frame is a box body welded from stainless steel plates, which has a protective effect on the cables. However, for photovoltaic power generation projects in some areas, photovoltaic panels are installed at a high level, and livestock such as cattle and sheep often graze below, causing the bridge frame to be trampled and damage the cables. Utility Model Content

[0003] The utility model aims to provide a composite cable bridge to prevent cattle and sheep raised at the bottom of photovoltaic panels from stepping on cables.

[0004] The technical solution adopted by the utility model is a composite cable bridge, comprising a strip-shaped box body and a strip-shaped box cover, the box body is a U-shaped cross-section structure, the cover is an inverted U-shaped structure, the sealing cover is closed at the upper opening of the box body, and the box body is filled with a coarse sand layer.

[0005] Preferably, a grille is provided in the box body, and the cables pass through the grille holes of the grille.

[0006] Preferably, the grille is inserted into the slots on both sides of the box body.

[0007] Preferably, both sides of the upper end of the box body are provided with external bosses, and the inner sides of both ends of the box cover are provided with card slots, and the external bosses are carded into the card slots.

[0008] Preferably, a sealing strip is provided at the upper end of the box.

[0009] Compared with the prior art, the beneficial effect of the utility model is that by filling the bridge with a coarse sand layer, it plays a role in auxiliary support and protection of the cables, preventing the cattle and sheep raised at the bottom of the photovoltaic panels from stepping on the cables. The coarse sand has good air permeability and can also play a better role in heat dissipation. In addition, the grid is used to organize the cables to pass through separately, which is convenient for limiting and avoiding short circuit between the two cables after the surface is damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a cross-sectional schematic diagram of the utility model. DETAILED DESCRIPTION

[0011] The present invention will be further explained below in conjunction with the accompanying drawings to facilitate better understanding by those skilled in the art.

[0012] Example 1

[0013] like Figure 1As shown, a composite cable bridge comprises a strip-shaped box body 1 and a strip-shaped box cover 2. The box body 1 is a U-shaped cross-section structure, and the cover 2 is an inverted U-shaped structure, which is sealed at the opening at the upper end of the box body 1. The box body 1 is filled with a coarse sand layer 3, which plays a role in auxiliary support and protection of the cable to prevent cattle and sheep raised at the bottom of the photovoltaic panel from stepping on the cable. In addition, the coarse sand has good air permeability and can also play a better heat dissipation role.

[0014] The box body 1 is provided with a grid 4, and the cable passes through the grid hole of the grid 4, which is convenient for limiting and avoids short circuit between two cables after the skin is damaged. The grid 4 is inserted into the card slots on both sides of the box body to play a positioning role.

[0015] Furthermore, external bosses 5 are provided on both sides of the upper end of the box body 1, and clamping grooves 6 are provided on the inner sides of both ends of the box cover 2. The external bosses 5 are clamped into the clamping grooves 6 to achieve a better locking effect.

[0016] Furthermore, a sealing strip 7 is provided at the upper end of the box body 1 to provide waterproofing.

[0017] The above-mentioned embodiments are only for describing the preferred implementation of the utility model, and are not intended to limit the scope of the utility model. Without departing from the design spirit and principle of the utility model, various modifications and improvements made by those skilled in the art to the technical solution of the utility model shall fall within the protection scope determined by the claims of the utility model.
