Photovoltaic cell board cleaning device's track mechanism

The utility model relates to a photovoltaic cell board cleaning device's track mechanism, this track mechanism contain the upper and lower rail that sets up both sides about the photovoltaic panel unit respectively. Wherein, the cladding all around of photovoltaic panel unit has the framework, and the inside bending type in upper and lower both sides of framework becomes borduring of free accommodation photovoltaic panel unit. And this track mechanism still contains the upper bracket and the lower carriage of fixed upper and lower rail respectively, and upper and lower support has the clamping part that is used for cliping photovoltaic panel unit framework respectively. Wherein, upward, be equipped with the bound hook portion of framework that catches on in the lower clamping part respectively. Compare with prior art because in cleaning device, the fixed upper bracket of going up the rail have respectively with the fixed lower carriage of rail down go up, lower clamping part, and go up, be equipped with hook
