Truss type photovoltaic array of large-open-distance support foundation

Abstract

A truss-type photovoltaic array of a large-spacing support foundation comprises a plurality of columns of photovoltaic supports extending along a first direction, and each column of photovoltaic supports is installed on each column of support foundation; the photovoltaic main shafts / purlines extend along a second direction and are arranged on each row of photovoltaic brackets and are used for mounting photovoltaic modules; the cross beams are bridged on every two rows of support foundations in the first direction, at least one photovoltaic main shaft / purline used for installing a photovoltaic module is arranged in the middle of each cross beam, and the cross beams, the support foundations and the photovoltaic main shafts / purlines form a truss structure. The movable space below the photovoltaic array is enlarged, the cross beams can also serve as laying channels of photovoltaic cables, the cross beams are connected with the support base and the photovoltaic main shaft to form truss structures, and the overall cost is reduced while safety and reliability of the photovoltaic array are guaranteed.

Description

[0001] Field of Invention [0002] The invention relates to a solar photovoltaic array, in particular to a truss-type photovoltaic array with a large opening distance bracket foundation. Background technique [0003] Solar photovoltaic panels, especially large-area solar photovoltaic panel arrays or photovoltaic systems, can fully receive sunlight when they are installed on the ground or on water. Especially the photovoltaic support array with automatic tracking device can track the movement of the sun in real time, and adjust the orientation of photovoltaic modules (for example, the movement from east to west), so that the sunlight directly hits the light-receiving plane of the photovoltaic panel and improves the photovoltaic power generation. However, existing photovoltaic support arrays such as figure 1 As shown in the photovoltaic support array 10, a column of photovoltaic modules 12 is installed on a column of support foundations 11, and the amount of the support foundat...

AI Technical Summary

Problems solved by technology

However, existing photovoltaic support arrays, such as figure 1 The photovoltaic support array 10 shown is to install a row of photovoltaic modules 12 on a row of support foundations 11, and the consumption of the support foundation is large and the cost is high

Moreover, in order to improve the utilization rate of the land or water area, the distance between two adjacent columns of support foundations 11 of the existing photovoltaic support array is designed to be small, so that the activity space on the ground or water surface is reduced, which is not conducive to project construction and daily life. maintenance, and is not conducive to agricultural farming on the ground or fishing operations on the water

Furthermore, in the prior art photovoltaic support array, the power cables and power cables in the east-west direction need to lay additional bridges or dig cable trenches on the ground, which brings problems such as complex construction and high cost.
