Embodiment 1

[0040] This embodiment provides a track system for cleaning across rows of a flat single-axis tracking system, and a schematic diagram of a part of its structural units is as follows figure 1 As shown, it includes a flat single-axis tracking system, a rowing track system and a lifting system; the flat single-axis tracking system includes a component and a rotating shaft, the component is installed on the rotating shaft and the component can rotate with the rotating shaft, The over-row track system includes an inter-row track and a transfer table, the transfer table is installed at the end of the inter-row track, and the transfer table corresponds to the position of the assembly.

[0041] The lifting system in this embodiment includes two lifting motion units arranged in parallel, a fixing unit and a separate guiding and limiting device, wherein the upper part of the lifting motion unit is fixed on the rotating shaft of the flat single-axis tracking system, and the lifting motio...

Embodiment 2

[0046] This embodiment provides a method for cleaning using the track system in Embodiment 1, the schematic flow chart of which is as follows Figure 7 shown, including the following steps:

[0047] S1, first rotate the components of the flat single-axis system to a horizontal or slightly inclined state, and the over-row track system reaches the designated position under the action of the lifting system;

[0048] S2, the cleaning robot judges whether the horizontal single-axis tracking system is in the robot cleaning mode, if yes, judges whether the lifting system is self-locked, if yes, starts the cleaning robot, otherwise, restarts the cleaning robot after the aforementioned conditions are met;

[0049] S3, the started cleaning robot runs along the inter-row track to the conversion table at the end of the current row of components;

[0050] S4, the cleaning robot climbs up the corresponding components of the conversion platform along the conversion platform, and starts to c...

Abstract

The invention discloses a track for the row-crossing cleaning of a flat single-axis tracking system, a cleaning system and a method for the row-crossing cleaning of a flat single-axis tracking systemand belongs to the technical field of photovoltaic assembly cleaning. The track system comprises assemblies, a rotating shaft, a lifting system and a row-crossing track system; the assemblies are installed on the rotating shaft and can rotate along with the rotating shaft; the row-crossing track system is installed on the lifting system; and one end of the lifting system is fixed on the rotating shaft of the flat single-axis tracking system, and the other end of the lifting system is connected with the row-crossing track system. The row-crossing track can continuously ascend and descend according to the difference of the angles of the assemblies, so that the influence of the shielding of track shadows on the power generation of the assemblies can be effectively avoided; flexible connectionbetween a lifting motion unit and the rotating shaft of the tracking system can reduce internal stress, so that a robot can be directly stopped on the track; and the track system can unload wind power when being subjected to strong wind, and influence on the flat single-axis tracking system is reduced.

Description

technical field [0001] The invention relates to the technical field of photovoltaic module cleaning, in particular to a track, a cleaning system and a method for cross-row cleaning of a flat single-axis tracking system. Background technique [0002] The dust accumulation on the surface of photovoltaic modules has a great impact on the power generation of the modules. In order to ensure the income of the power station, many owners of photovoltaic power stations are exploring the installation of module cleaning robots. The radiation utilization efficiency of the photovoltaic power station with the flat single-axis tracking system is higher than that of the fixed-support photovoltaic power station, so the improvement effect of its power generation will be more obvious. At present, for the cleaning of photovoltaic power plants with flat single-axis tracking systems, it is mainly to rely on manpower to complete the cross-row cleaning or to connect the front and rear rows by pilin...
