Solar photovoltaic main shaft bearing structure

Abstract

The invention provides a solar photovoltaic main shaft bearing structure. The solar photovoltaic main shaft bearing structure comprises bearing sleeves, bearing inner rings and rail grooves, wherein each bearing sleeve is composed of two opposite buckled disc-shaped structures; the rear end of each bearing sleeve is vertically connected with an oil storage cylinder; a connecting shaft sleeve is connected between the bearing sleeves; the two ends of the connecting shaft sleeve are each fixedly connected with one bearing inner ring; bearing outer rings are rotationally connected into inner grooves of the bearing sleeves; the bearing inner rings are internally connected into the bearing outer rings; fixing discs are fixedly arranged on the outer parts of the bearing outer rings through bolts;and the outer ends of the fixing discs are fixed on the bearing sleeves. According to the solar photovoltaic main shaft bearing structure, the inner ends of the oil storage cylinders communicates with the interior of buckling grooves of the bearing sleeves, and an oil injection nozzle is arranged in the middle of the outer wall of each oil storage cylinder, so that part of lubricating oil is always stored in the oil storage cylinder to keep long time lubricating conveniently.

Description

technical field [0001] The present invention relates to the technical field of photovoltaic power generation, and more specifically relates to a solar photovoltaic main shaft bearing structure based on solar photovoltaic. Background technique [0002] Solar photovoltaic power generation is a technology that accepts incident sunlight by using an array formed by a subsystem of solar photovoltaic modules, converts light energy into electrical energy through photovoltaic conversion, and collects the generated electrical energy for use. [0003] Existing solar photovoltaic systems usually use bracket structures to install solar photovoltaic arrays, especially large-area solar photovoltaic arrays. The bracket structure can generally fix the solar photovoltaic array, so that the solar photovoltaic array can work for a long time. When the bracket structure is used for installation, the bracket structure needs to be installed on the main shaft. In order to make the bracket structure...

AI Technical Summary

Problems solved by technology

[0006] To sum up, the present invention provides a solar photovoltaic spindle bearing structure based on solar photovoltaics. Through structural and functional improvements, it can solve the problem of maintenance during use because most of the solar photovoltaic power generation panels are installed at relatively high positions. It is inconvenient for personnel to go up for maintenance frequently, and the lubricating oil is always consumed because the photovoltaic power generation panel needs to follow the sunlight for rotation. On the other hand, the photovoltaic power generation The problem that the service life of bearing parts is greatly reduced
