Solar energy assembly used for sun tracking system

Abstract

The invention discloses a solar energy assembly used for a sun tracking system, which comprises a solar energy assembly and an assembly support, wherein one end of the solar energy assembly is rotatably connected with one end of the assembly support; an elastic mechanism is arranged between the other end of the solar energy assembly and the other end of the assembly support; the elastic modulus k of the elastic mechanism is shown as follows: k is more than or equal to G / 2a and less than or equal to F / L or k is more than or equal to F / L and less than or equal to G / 2a and L is less than or equal to M, wherein a is the displacement of the assembly for overcoming the elastic mechanism under a flat state under the effect of the dead weight, L is the rotating displacement generated on wind acting on the plane of the assembly at the maximum design wind speed, F is the force of the wind acting on the plane of the assembly at the maximum design wind speed, G is the dead weight of the assembly, and M is the maximum bearing deformation of the elastic mechanism. The invention has the advantages that an elastic assembly installing mode is realized by using the mechanism with light weight and small occupied space, thereby being beneficial to the wind resistance, the snow pressure resistance, the hailstone resistance and the vibration resistance of the sun tracking system.

Description

technical field [0001] The invention belongs to a solar component used in a solar tracking system, and relates to a solution for components in the solar tracking system to avoid wind, resist snow pressure, resist hail attack and resist earthquakes. Background technique [0002] At present, the installation of components in the application is mostly fixed installation. [0003] Similar to the component installation mechanism of the present invention, a spring mechanism is used as the component installation force connection mode, and a bearing is installed at the center point of the long side of the rectangular component as a rotating shaft for the component to be twisted under the action of an external force. [0004] The fixed installation method is mostly used in the non-tracking fixed bracket installation method. When used in a sun tracking system, due to the diversity of its working conditions, it is necessary to fully consider the avoidance posture of the sun-facing sur...

AI Technical Summary

Problems solved by technology

Its spring mechanism will not only deform vertically but also easily deform laterally under the pressure change state, and it is easy to be entangled and clamped with the gap of the mechanism or the bracket structure, causing non-self-repairable failures or even permanent damage spring mechanism

In addition, its rotating shaft is installed on the center of a pair of symmetrical sides of the rectangular component. Under the action of the wind, the forces on both sides of the shaft on the windward surface of the component are basically balanced, so that the probability of a large torsion is greatly reduced, and more Most of the time it is just vibration, which greatly reduces the wind resistance it wants to achieve

Moreover, the seismic performance of the structure is poor, and under the action of instantaneous large force, it cannot enter the elastic state instantly, and thus cannot overcome the damage of the earthquake.
