Prestressed photovoltaic support at small inclination angle

Technical Field

The utility model relates to a photovoltaic support technical field especially relates to a prestressed cable truss photovoltaic support at little inclination.

Background

The photovoltaic bracket is used for supporting a solar panel in a solar photovoltaic power generation system. The traditional photovoltaic support is a rigid support and generally comprises a stand column and purlines, photovoltaic modules are arranged on the rigid purlines in an array mode, the flexible photovoltaic support is characterized in that the rigid purlines are changed into steel strands to form a flexible cable structure, and the photovoltaic modules are directly arranged on two module mounting cables. And the two assembly mounting cables are positioned on different planes and are respectively called as an upper cable and a lower cable, so that the photovoltaic assembly forms a certain inclination angle after being mounted, and the sunlight can be better received.

The flexible support is in a mode of tensioning a prestressed cable between two fixing points, and the two fixing points adopt a rigid foundation to provide a reaction force, so that large-span installation can be realized, the installation range of a photovoltaic system is widened, and the cable force is in direct proportion to the quadratic power of the span and in inverse proportion to the deflection, so that the prior art generally selects a transverse component with limited span, generally has large deflection, complicated side anchoring measures, poor wind resistance, severe wind-induced vibration, long system construction period, high average cable force utilization level, large cable force variation and short steel cable fatigue life.

SUMMERY OF THE UTILITY MODEL

The utility model provides a prestressing force photovoltaic support at little inclination can form the zero amount of deflection plane of unit mount, and the anti-wind ability of reinforcing system suppresses torsional vibration and the vertical vibration of subassembly plane under the wind load effect, reduces the atress level and the cable force level of prestressing force suspension cable, promotes cable body fatigue life, further reduces the material quantity, the lowering system cost.

The prestressed photovoltaic support with the small inclination angle changes the plane direction relation between a cable and a component, and comprises a cable body, wherein anchor points are arranged at two ends of each lock body, a photovoltaic component is arranged between the two lock bodies, a component mounting part is arranged between each lock body and each photovoltaic component, the cable body is arranged between every two adjacent rows of components, and the using amount of the component mounting cable is reduced to one half of that of the traditional scheme.

The assembly mounting part adopts an adapter part form, the photovoltaic assembly inclination angle is realized through the height difference of two ends of the assembly mounting part, all photovoltaic assembly cables are located at the same mounting height, the mode of realizing the assembly inclination angle through the height difference of the assembly mounting cables in the traditional scheme is distinguished, and the length and the inclination angle of the adapter part are reasonably designed.

The assembly mount provides a mounting point for the assembly as shown in figure 4, avoiding direct hard contact between the photovoltaic assembly and the cable.

The assembly mounting piece is formed by casting alloy steel, and consists of a plurality of parts so as to form clamping and holding of the cable body after assembly; a screw hole or a mounting hole position is reserved at the tail end of the adapter piece so as to be convenient for connecting and mounting with the component and form a rotational freedom degree between the component and the adapter piece in the direction parallel to the cable axis.

Bearing cables are arranged below two adjacent lock body units in parallel, vertical load of a photovoltaic assembly is transmitted to the bearing cables through rigid support rods arranged at intervals, the upper assembly cable and the lower bearing cables form a truss string structure, each three groups of the rigid support rods are one unit and comprise a support rod A, a support rod B and a support rod C, and different numbers of rigid support rod units are selected according to actual span.

The transverse connecting rod pieces are added among the cable trusses, and the vertical vibration, the torsional vibration amplitude and the phase inconsistency of a single cable truss caused by the nonuniformity of a spatial wind field are utilized, so that the suppression and the drag action of the vibration among the cable trusses are realized, and the wind-induced vibration level of a system is obviously reduced;

the average cable force level is improved, so that the breaking force of the steel strand with the conventional specification in the industry is fully utilized, and the economic performance of the scheme is improved;
