Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic cleaning, and in particular to a device for realizing automatic transport between rows of photovoltaic arrays of a cleaning robot. Background Art

[0002] The existing photovoltaic cleaning methods are divided into manual and automated equipment cleaning, but both have the following defects:

[0003] 1. Defects of manual cleaning methods:

[0004] The efficiency is extremely low, and it takes a lot of time and manpower, which cannot meet the cleaning needs of large-scale photovoltaic arrays. The high labor cost increases the operating cost of photovoltaic power stations. The cleaning quality is difficult to guarantee, and it is easy to have incomplete cleaning, which affects the power generation efficiency of photovoltaic panels.

[0005] 2. Defects of some automated equipment:

[0006] The transfer process requires manual intervention, and the degree of automation is not high, resulting in an unsmooth cleaning process and limited efficiency improvement. The single function cannot adapt to the diverse layout and cleaning needs of photovoltaic panels. For example, for photovoltaic panels of different heights and angles, the position and posture of the cleaning robot cannot be flexibly adjusted. The lack of stability and reliability makes it easy to fail during operation, affecting the normal progress of cleaning work. It may cause the cleaning robot to fail to reach the designated location accurately, or unexpected situations may occur during the transfer process, causing damage to the photovoltaic panels and cleaning robots. The compatibility of some equipment is poor and can only be used with cleaning robots of specific models or specifications, which limits its scope of application. In terms of energy utilization, there may be a problem of high energy consumption, which increases operating costs. The operation and maintenance of some equipment are more complicated, requiring professional personnel to operate and repair, which increases manpower and training costs. Summary of the invention

It can monitor and adjust the operating status of each system in real time to ensure the stable operation of the device. It can accurately control the travel drive system, lifting system and flip system, so that the shuttle can complete the transfer task according to the preset procedures and requirements.

[0042] An embodiment of the present invention provides a device for realizing automatic transport between rows of a photovoltaic array by a cleaning robot, comprising the following operating steps:

[0043] S1. Input the cleaning task parameters. The device completes self-check. If normal, the cleaning task will be started. If abnormal, the staff will be notified for maintenance.

[0044] S2. During the cleaning process, the power of the device is continuously monitored. If the power of the shuttle bus is less than 20% and the cleaning robot is less than 30%, it will automatically return to the charging station for charging or notify the staff to replace the battery;

[0046] Example 2:

[0047] In a photovoltaic power station, the device of the present invention is used to carry out the transportation work of the cleaning robot. The model of the cleaning robot is B33T, the overall dimensions are 650560340mm (excluding the roller brush), the weight is 35kg (including 20Ah battery, excluding the roller brush), the maximum overall dimensions are 14001300340mm (including the roller brush), and the maximum weight is 50kg (including 20Ah battery, including the roller brush).

After arriving at the designated position, the lifting system accurately lifts the ferry car to the appropriate position according to the height of the photovoltaic panel, and the flipping system flips the ferry car to the angle consistent with the inclination angle of the photovoltaic panel at the same time, and then the cleaning robot moves to the solar photovoltaic panel by itself to carry out cleaning work. During the whole process, the battery power system supplies power stably, and the control system accurately controls the coordinated operation of each system. Through actual testing, the device can accurately and efficiently complete the transportation task of the cleaning robot, and the cleaning efficiency is improved by 50% compared with before, and the labor cost is reduced by 70%.

After using the device of the present invention, no matter how the layout of the photovoltaic panels changes and what the inclination angle is, the shuttle bus can accurately transport the cleaning robot to the designated location. For example, in a cleaning task, the inclination angle of the photovoltaic panel is 12°, and the flipping system of the shuttle bus can quickly and accurately lift and flip the top plate to 12°, allowing the cleaning robot to move smoothly to the photovoltaic panel for cleaning. After a period of operation, the stability and reliability of the device have been fully verified, and no failures or abnormalities have occurred, effectively ensuring the smooth cleaning work of the photovoltaic power station.
