Description

Rear upright post of shared photovoltaic bracket and photovoltaic bracket system Technical Field The invention relates to the technical field of photovoltaic brackets, in particular to a shared photovoltaic bracket rear upright post and a photovoltaic bracket system. Background The rear column of the photovoltaic support is a key component for bearing the load of the rear end of the photovoltaic module, and the connection reliability of the rear column directly influences the overall stability of the system. The existing rear upright post is usually fixed at any position of the guide rail through bolts, and the connecting mode has the following defects that firstly, the joint of each guide rail often becomes a weak link of the whole bracket system, and because when the rear upright post bears external forces such as wind load, snow load and the like, the load is transmitted to the joint of the guide rail, so that stress concentration is easily caused, the guide rail is deformed or connected loose, the service life of the system is influenced, and the joint of the rear upright post and the guide rail often avoids the joint of the guide rail. Secondly, the existing photovoltaic bracket system generally adopts independent rear posts to support single photovoltaic modules (each module needs to be provided with an independent rear post), and certain installation gaps are reserved between adjacent modules due to the arrangement, so that the roof space utilization rate is low, and the installed capacity of unit area is limited.
