Description

Photovoltaic support convenient to overhaul and maintain Technical Field The invention relates to the technical field of photovoltaic equipment, in particular to a photovoltaic bracket convenient to overhaul and maintain. Background The photovoltaic power generation is used as a core utilization mode of clean renewable energy sources, and is widely applied to various scenes such as roofs, deserts, beaches and the like, and a photovoltaic module is easily influenced by natural environments such as dust, rainwater, wind sand and the like in a long-term use process, so that the problems of surface stains, module breakage, circuit aging and the like are easily caused, and regular overhauling and maintenance are needed to ensure the photovoltaic power generation efficiency and the equipment operation safety. Among the prior art, many pass through bolt riveting when photovoltaic board installs and fix, need change when single or a plurality of photovoltaic board take place to damage, though partial photovoltaic support tries to set up height and angle modulation, can highly reduce in order to maintain the operation with the photovoltaic board, still need dismantle a large amount of bolts with the help of specialized tool when dismantling the change alone to middle photovoltaic board, complex operation, and damage peripheral fragile subassembly easily in loaded down with trivial details operation in-process, fixing bolt exposes in the open air easily rusty card for a long time simultaneously, further increases the dismantlement degree of difficulty, reduce maintenance efficiency by a wide margin. And in the maintenance process of photovoltaic equipment, whether the junction box has the condition of ablation and poor contact or not needs to be checked, the MC4 connector is plugged, replaced or reworked and all arranged on the back of the photovoltaic panel when waterproof, but because the optical Fu Banbei cable is arranged between the brackets and is shielded, meanwhile, the cable on the back of the photovoltaic panel is aged, the cable is broken and the cable is worn out, and the cable or the cable is required to be rearranged, fixed and replaced, so that the single photovoltaic panel cannot be temporarily supported when the existing photovoltaic panel is overhauled, the circuit is inconvenient to overhaul, the operation difficulty of workers in the overhauling and maintenance process is increased, and the overhauling efficiency is influenced. In addition, in the overhaul maintenance of current photovoltaic support and the installation work progress of photovoltaic board, when carrying out dismantlement, installation and fastening operation to the mounting, operating personnel generally need trample photovoltaic board edge support, and the relevant operation of cooperation instrument completion again, this mode of operation not only leads to operation flow loaded down with trivial details, construction convenience not enough, has also improved operating personnel's security risk by a wide margin simultaneously.
