Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panel connection equipment, in particular to a track bridge mechanism for gaps between adjacent photovoltaic panels. Background Art

[0002] During the installation of photovoltaic arrays, photovoltaic panels of uniform specifications are typically used. During operation, a solar tracking device (a device that keeps the panel's main optical axis parallel to the sun's rays, improving the panel's power generation efficiency) is installed at the bottom of the panel. However, the installation of the solar tracking device creates gaps between adjacent panels, preventing the panel cleaning robot from smoothly moving from one panel to another during operation, thus preventing the effective cleaning of the entire photovoltaic array. In the prior art, bridges are used to connect multiple photovoltaic panels to enable the panel cleaning robot to cross these gaps.
