Description

Guide plate assembly, photovoltaic assembly and photovoltaic array

Technical Field

The utility model relates to a photovoltaic technology field, concretely relates to guide plate subassembly, photovoltaic module and photovoltaic array.

Background

Solar energy is a clean, safe, reliable renewable energy source. The development of the solar power generation technology can effectively reduce energy efficiency, reduce pollution, adjust energy structure and realize sustainable development.

The photovoltaic power generation is a power generation technology for converting solar energy into electric energy by using a solar cell panel, and the photovoltaic tracking support is a power device capable of adjusting the inclination angle of the solar cell panel in real time so as to enable the solar cell panel to face the sun at any time. The photovoltaic tracking support is applied to effectively improve the solar radiation quantity received by the photovoltaic array, so that the overall generated energy of the photovoltaic power generation system is improved.

The photovoltaic tracking support is a large-span torsion structure which rotates by means of central torque. Along with the increase of the size of the photovoltaic module and the increase of the whole length of the tracking support, the photovoltaic module can be influenced by the wind environment, the influence is transmitted to the photovoltaic tracking support, the photovoltaic tracking support generates flutter under the action of wind load, and the vortex vibration and other wind-induced vibration phenomena cause the damage of the support structure. Meanwhile, the wind pressure and the wind torque are also important influencing factors in the structural design and the cost control of the photovoltaic tracking support.

At present, in order to reduce the influence of wind load on a support structure, the inclination angle of a photovoltaic module is usually adjusted to zero degree in windy weather, namely, the inclination angle is parallel to the ground, and the wind load is reduced by reducing the windward area of a photovoltaic tracking support. However, the tracking support is prone to flutter at a zero-degree inclination angle, which damages the structure, so that the critical unstable wind speed of the tracking support needs to be increased by multi-point driving, namely, a plurality of speed reducers, and the electric control cost of the tracking support is greatly increased. In order to avoid the occurrence of flutter, the inclination angle of the photovoltaic module can be adjusted to an angle of large wind in windy weather. At the moment, the wind-induced vibration phenomenon of the photovoltaic tracking support is dominated by vortex vibration, the structure cannot be damaged, and vibration generated by the vortex vibration can be effectively inhibited by installing a damper and the like.
