The bottom of the left guide rail and the right guide rail are all provided with the guide rail bracket 4 of its supporting effect, and the guide rail bracket 4 is fixedly arranged on the wall mount. The end place of left guide rail and right guide rail is all provided with synchronous wheel 6, and synchronous wheel 6 is fixedly installed on the gear fixed plate 5, and gear fixed plate 5 is arranged between guide rail 13 and guide rail support 4, and gear fixed plate 5 also plays a role The role of strengthening the support for the guide rail 13. Synchronous wheel 6 can adopt synchronous pulley or synchronous sprocket wheel, is provided with synchronous wheel shaft 12 between two synchronous wheels 6, and synchronous wheel shaft 12 can be selected as synchronous belt wheel shaft or synchronous sprocket shaft according to synchronous wheel 6. A transmission belt 7 is arranged between the transmission motor assembly 17 and the synchronous wheel 6, and the transmission belt 7 can rotate between the two when the transmission motor assembly 17 is in operation. Driving belt 7 can be set as toothed belt or chain according to use needs.

The transmission belt 7 is connected to the pulley assembly provided on the first group of photocell assemblies 23, and a hook 19 is arranged between two adjacent groups of photocell assemblies. Fold inward.

A dust removal assembly 15 is also arranged between two adjacent photocell assemblies. The dust removal assembly 15 includes a housing 24 and a silica gel strip 25 for wiping off the dust on the surface of the photocell assembly. The dust removal assembly 15 is arranged in the two adjacent photocell assemblies. A hook 19 is provided at the front end of the relatively lower photocell module, and a hook 19 is provided at the rear end of the relatively higher photocell module among two adjacent photocell modules, and a hook body used in conjunction with the hook 19 is provided on the housing 24 26. Like this, transmission motor assembly 17 runs, and when driving the first group of photocell assemblies 23 to stretch outwards by transmission belt 7, arranging hook 19 and hook body 26 will hang on one by one between adjacent two groups of photocell assemblies, thereby successively each group of photocell assemblies toward Stretch out. When the unfolded photocell assembly needs to be folded in, the transmission motor assembly 17 reverses its rotation, and the first group of photocell assemblies 23 starts to move backward, and the pulley assembly arranged on it will abut against the pulley assembly provided on the latter group of photocell assemblies. That is, when retracting, the pulley assembly provided on the previous group of photocell assemblies will abut against the pulley assembly provided on the rear group of photocell assemblies, thereby driving each group of photocell assemblies to be folded step by step.
