Sunken ventilation clerestory

A sunken ventilation clerestory comprises a roof beam and a roof panel arranged on the roof beam, and the roof panel is of an inverted-V-shaped structure. At least one notch is preset in the roof panel; each notch is provided with a low cover plate used for covering the notch. The two sides of the low cover plate are arranged on the two sides of the notch, the top of the low cover plate is lower than the top of the roof panel so that a preset height difference can exist between the low cover plate and the roof panel, the ventilation opening is formed through the preset height difference so that a sunken clerestory can be formed, the use of a protruding clerestory is avoided, and the use cost of the clerestory is reduced. The projection type clerestory prevents the shadow of the projection type clerestory from shielding the solar cell panel, reduces the adverse effect on the power generation efficiency of the solar cell panel on the roof, and is simpler, more stable and more reliable in structure on the premis
