Description

Technical Field

Background Technology

[0002] With the rapid development of the new energy industry and the increasing scarcity of land resources, flexible support photovoltaic power generation systems for mountainous areas have emerged. Their strong adaptability to terrain allows for easy construction in various complex terrains such as ravines and valleys. Furthermore, their high land utilization rate and environmental friendliness make them a crucial direction for the development of the photovoltaic industry. However, the steep slopes, varied terrain, and complex geological conditions of mountainous areas, coupled with the large spans of flexible support photovoltaic systems (ranging from 10 to 60 meters), present numerous challenges to their installation. Many flexible support systems are installed in mountain valleys for convenient installation and transportation. However, mountain valleys have strong winds that blow diagonally from the bottom to the top, making it difficult to achieve strong wind resistance for the flexible support systems a problem that needs to be solved on-site.

[0007] A method for installing wind-resistant cables for three rows of horizontally arranged flexible photovoltaic power generation supports in a mountain valley: First, determine the wind direction in the valley. If the wind comes from the right front of the three horizontally arranged flexible photovoltaic power generation supports, then install the wind-resistant cables according to the following steps: The first step is to set the first ground anchor on the hillside slope on the right front side of the first row of prestressed steel strands, and to set the first ground anchor between the first row of wind-supported angle steel and the top crossbeam of the first row of side columns. The second step is to set up a second ground anchor on the hillside between the first row of prestressed steel strands and the second row of prestressed steel strands, and to set the second ground anchor between the second row of wind-supported angle steel and the top crossbeam of the second row of central column. The third step is to set up a third ground anchor on the hillside between the second row of prestressed steel strands and the third row of prestressed steel strands, and to set the third ground anchor between the third row of wind-supporting angle steel and the top crossbeam of the third row of central column. Step 4: Connect the first wind cable between the first ground anchor and the front end of the first row of wind support angle steel, and connect the third wind cable between the second ground anchor and the rear end of the first row of wind support angle steel, so that the first wind cable, the first row of wind support angle steel and the third wind cable form a trapezoidal frame. Step 5: Connect the second wind cable between the first ground anchor and the second row of wind cable support angle steel, and connect the fifth wind cable between the third ground anchor and the rear end of the second row of wind cable support angle steel, so that the second wind cable, the second row of wind cable support angle steel and the fifth wind cable form a trapezoidal frame spanning rows on both sides. Step 6: Connect the fourth wind cable between the second ground anchor and the front end of the third row of wind cable support angle steel, and connect the sixth wind cable between the third ground anchor and the rear end of the third row of wind cable support angle steel, so that the fourth wind cable, the third row of wind cable support angle steel and the sixth wind cable form a trapezoidal frame spanning one row. The cross-row X-shaped intersection of the second and third wind cables, and the cross-row X-shaped intersection of the fourth and fifth wind cables, connect the three rows of parallel photovoltaic power generation flexible supports into a stable whole. The first and sixth wind cables are arranged at an angle to the windward direction, so that the entire support system has the function of resisting wind pull.

[0008] This invention constructs a wind-supporting angle steel between the side columns and the central column. The wind-supporting angle steel is parallel to the top crossarm of the side columns and the top crossarm of the central column. Ground anchors are set in the direction perpendicular to the three rows of prestressed steel strands. By combining the wind-supporting cables between the ground anchors and the wind-supporting angle steel, a trapezoidal tensioning frame is constructed in the windward longitudinal direction, which tightens the three rows of prestressed steel strands together, thus resisting strong winds in the mountain valley and ensuring the safe operation of the photovoltaic panels installed on the prestressed steel strands.
