VENTILATION EQUIPMENT OF HOUSE FOR PREVENT INFLOW OF RAIN OR SNOW

摘要

The present invention relates to a ventilation device for a greenhouse and, more specifically, to a ventilation device for a greenhouse, capable of preventing rain or snow from flowing into a greenhouse and ventilating air in the greenhouse in a selective manner. In addition, the ventilation device for a greenhouse has excellent constructability and requires low installation costs by modularizing a roof. The ventilation device for a greenhouse includes: a house (10) having a vent (11) at an upper end; a blocking member (20) including a base plate (21) fixed to the upper end of the house and a blocking wall (22) extended upward from the base plate; a housing member (30) including a base frame (31) fixed to a position separated by a predetermined distance from the blocking wall to the outside, wherein the housing member (30) includes multiple housing frames (32) crossing an upper space of the vent at the position separated from the upper end of the blocking wall toward the upper side in the predetermined distance; and a cover member (40) installed on the upper side of the housing frame. A lower end of the cover member has a ventilation space (S) by being separated from the base frame, and an upper end of the blocking wall is higher than the lower end of the cover member.
