The present invention relates to a light-blocking device for a solar heat collector. The light-blocking device, which includes multiple supports, has a support frame with multiple vertical and horizontal frames connected to one another installed on the supports, has a solar heat connector installed on the upper surface of the support frame, and blocks sunlight concentrated on the solar heat collector. The device comprises: a fixing bar having a fixing part formed on an upper part connected and formed on both ends of the supports; a rope connected to the fixing part to fold and unfold a light-blocking screen; and an operating means mounted on the supports to operate the rope. As described above, the present invention enables a worker to selectively block radiant energy by folding or unfolding the light-blocking screen via manual and simple operation and facilitates the installation and disassembly of the light-blocking device as the light-blocking device blocks heat and light excessively transmitted to the solar heat collector via a method for winding or unwinding the rope around the solar heat collector. |
