Description
Technical Field
[0001] This utility model relates to the field of agricultural facility technology, and more specifically, to a gutter and greenhouse structure. Background Technology
[0002] Glass greenhouses are widely used structures for plant cultivation and agricultural production. Because glass greenhouses can control factors such as temperature, humidity, light, and carbon dioxide concentration, they provide a suitable and stable environment for plant growth, unaffected by climate or outdoor temperature and humidity. Glass greenhouses can provide the necessary heat and light for growing plants, allowing for fully controlled plant growth and significantly improving crop yield and quality.
[0003] In greenhouse structures, gutters serve multiple functions, including drainage and load-bearing. For example, gutters collect rainwater and melted snow from the roof, effectively guiding this water to the ends of the greenhouse or a specific drainage system to prevent rainwater from accumulating on the roof and causing leaks or damage to the greenhouse structure. In addition, gutters also serve as load-bearing structures and connect to the roof, supporting roof equipment and personnel for maintenance, as well as rain and snow. Gutters can connect to structural components such as the greenhouse's A-frame beams, firmly linking the various parts together to support and stabilize the entire greenhouse structure, forming a unified spatial structure and improving the greenhouse's resistance to wind and earthquakes.
[0004] However, when the humidity is high and the temperature difference is large inside the greenhouse, the hot air comes into contact with the low-temperature roof covering material (such as glass, PC board, film, etc.), and water vapor condenses to form condensate. If the condensate is not drained in time, it may drip onto the crop leaves and cause diseases, corrode metal structures, or lead to excessively high indoor humidity. Utility Model Content
