Abstract

The cable bridge structure for the mountain photovoltaic project comprises a plurality of sets of supports arranged at intervals, each support comprises a front stand column, a rear stand column, steel plates and a cross arm, the bottoms of the front stand column and the rear stand column are connected with the steel plates in a welded mode respectively, the steel plates are fixed to a rock through expansion bolts, and the cross arm is arranged between the front stand column and the rear stand column. The cross arm is fixed with the front stand column and the rear stand column through bolts, a cable trough box is arranged on the cross arm, and the cable trough box is fixed with the cross arm through bolts. The stand columns and the cross arms are all made of angle steel. The distance W between the stand columns of every two adjacent sets of supports ranges from 1.5 m to 2 m. The distance between the front stand column and the rear stand column is consistent with the width of the cable trough box. The cable bridge support can effectively overcome severe geological conditions, especially land parcels with exposed rocks, and can effectively fix the cable bridge support, so that the field construction efficiency is improved.

Description

TECHNICAL FIELD

[0001] The utility model relates to photovoltaic power generation technical field especially, it is a kind of cable bridge structure for mountain photovoltaic project. BACKGROUND

[0002] Current mountain photovoltaic project common cable laying mode has direct-burial laying, bridge laying and other ways, due to topography, geology and policy condition factor restriction, part mountain photovoltaic project adopts bridge laying mode, common cable bridge is to adopt two root insertion topography, middle through bolt fixed one cross arm (angle steel), cross arm is fixed cable slot box.

[0003] For mountain photovoltaic project, topography geology condition is complex, in the rock bare land, the column of cable bridge support is very difficult to insert hard rock, causes construction difficulty or delay situation. SUMMARY

[0004] The utility model discloses a kind of cable bridge structures for mountain photovoltaic project to overcome the shortcoming that existing cable bridge support cannot be effectively fixed on hard rock.

[0005] The utility model discloses a kind of cable bridge structures for mountain photovoltaic project technical scheme is: including several groups of interval arrangement support, the support includes column, steel plate and cross arm, the column is two root front and back, and steel plate is connected in the bottom of two root column front and back respectively and is welded, the steel plate is fixed on rock by expansion bolt, cross arm between two root column front and back, cross arm is fixed with two root column front and back by bolt, cable slot box is set on cross arm, cable slot box is fixed with cross arm by bolt.

[0006] Further, the column and cross arm are all angle steel.

[0007] Further, the interval W between the column of adjacent two groups of support is 1.5m-2m.

[0008] Further, the interval between two root column front and back is consistent with the width of cable slot box.

[0009] The utility model discloses a kind of cable bridge structures for mountain photovoltaic project beneficial effect is: can effectively overcome harsh geological conditions, especially rock bare land, can effectively realize the fixation of cable bridge support, to improve the construction efficiency of scene.
