Cable-stayed flexible photovoltaic bracket unit and photovoltaic bracket

Abstract

The invention discloses a cable-stayed flexible photovoltaic bracket unit and a photovoltaic bracket. The bracket unit comprises two oppositely arranged upright posts, a stabilization cable and a plurality of main diagonal cables are arranged between the two upright posts, and the two ends of the stabilization cable are respectively connected to the lower parts of the upright posts on the corresponding ends; all main diagonal cables are divided into two groups, each group at least comprises one main diagonal cable, the upper ends of all main diagonal cables of each group are connected to the upper parts of the upright posts on the corresponding ends, the lower ends of the two groups of main diagonal cables are connected with a cross beam, and connection points are uniformly arranged alongthe length direction of the cross beam, and the cross beam is horizontally arranged; and a plurality of slings are equidistantly arranged between the cross beam and the stabilization cable along the vertical direction, the upper ends of all slings are connected with the cross beam, and the lower ends of all slings are connected with the stabilization cable. By adoption of an optimized self-balancing prestressed cable system, the vertical stiffness of the structure is improved, and the vibration problem under the wind load is solved, thereby significantly improving the spanning capability of the photovoltaic bracket, further reducing the floor space, and having relatively high adaptability on complex terrain areas.

Description

technical field [0001] The invention discloses a cable-stayed flexible photovoltaic support unit and a photovoltaic support, and relates to the technical field of solar energy applications. Background technique [0002] In recent years, in order to adapt to the special erection environment, flexible photovoltaic support has become more and more popular. However, there are obvious deficiencies in the structure and structural system of the existing suspension cable flexible photovoltaic support: the direct connection structure between photovoltaic modules and flexible cables is complex and inconvenient to install , and the connection is unreliable; vibrations are prone to occur under wind loads, causing hidden cracks in the components. At the same time, as the span of the bracket increases, greater pre-tension is required to provide stiffness, and excessive pre-tension will lead to higher requirements on the boundary and a sharp increase in cost . Therefore, how to quickly an...
