Multi-point driving structure of cleaning beam and driving method of multi-point driving structure

Abstract

The invention provides a multi-point driving structure of a cleaning beam, and belongs to the technical field of driving structures. The multi-point driving structure of the cleaning beam comprises a cleaning beam assembly and a guide rail. A main motor driving assembly and a slave motor driving assembly are arranged at the two ends of the cleaning beam assembly correspondingly, and an auxiliary motor driving assembly is arranged between the main motor driving assembly and the slave motor driving assembly. The cleaning beam assembly comprises a cleaning beam and a cleaning assembly arranged at the lower end of the cleaning beam. The auxiliary motor driving assembly comprises a supporting wheel and an auxiliary motor arranged on the cleaning beam and used for driving the supporting wheel. The guide rails are located at the two ends of the cleaning beam correspondingly. The main motor driving assembly and the auxiliary motor driving assembly are used for driving the cleaning beam to move in the extending direction of the guide rails. The multi-point driving structure of the cleaning beam provided by the invention can effectively overcome the working condition of overlarge deflection and is suitable for a photovoltaic array with the extra length of more than 15 meters.

Description

technical field [0001] The invention relates to the technical field of driving structures, in particular to a multi-point driving structure of a cleaning beam and a driving method thereof. Background technique [0002] Photovoltaic power generation is a clean energy with very broad prospects. Dust in the air affects the power generation efficiency of photovoltaic modules. For this reason, cleaning equipment has been installed in each power station. However, each cleaning equipment operates independently, and the scope of cleaning is limited. The photovoltaic array width of large-scale factory roof power stations is getting wider and wider, and the requirements for cleaning equipment are getting higher and higher. [0003] The existing trackless driven cleaning beams are generally only suitable for photovoltaic arrays not exceeding 6 meters; rail-type cleaning beams are generally suitable for photovoltaic arrays not exceeding 10 meters, and are suitable for not exceeding 15...

AI Technical Summary

Problems solved by technology

[0005] In view of this, in order to solve the problem that the existing trackless driving cleaning beams are generally only suitable for photovoltaic arrays not exceeding 6 meters, the rail cleaning beams are generally suitable for For photovoltaic arrays exceeding 10 meters, it is suitable for photovoltaic arrays of no more than 15 meters when the size of the cleaning beam is increased. If the beam length exceeds the applicable range, the deflection will be too large due to the length of the beam, resulting in the cleaning equipment not being able to operate stably for a long time , once it exceeds the cleaning range, it needs to be equipped with multiple cleaning equipment or cannot install automatic cleaning equipment because there is no installation space for multiple cleaning equipment, which greatly increases the technical problem of manufacturing and installation costs. For this reason, the present invention provides a The multi-point driving structure of the cleaning beam can effectively overcome the working condition of excessive deflection and is suitable for photovoltaic arrays with a length of more than 15 meters
