Intelligent Greenhouse Agricultural Hydroponic System Glass Vegetable Growing Venlo Type Structure

1. Recently, the traditional Venlo-type structure of this smart glass greenhouse has been improved in China, changing the traditional small span of 3.2m and making it into a small span of 3.6m or 4.0m, thus deducing greenhouses with a span of 8.0m and 10.8m. Due to the increase in the span of the small roof, the strength of the simple aluminum alloy material used for the roof load-bearing structure is insufficient. Therefore, the roof load-bearing components are replaced by small-section square tubes. The dual role of the traditional aluminum alloy is simplified to only play the role of glass inlay.
2. In addition to increasing the span of the smart glass greenhouse, improvements to the Venlo-type structure can also increase the bay of the greenhouse from the traditional 3.0m to 4.0m, 4.5m, or even 6m or 8m. Due to the increase in size in the bay direction, the strength of the greenhouse's traditional gutter-supported roof structural plan in the bay direction will be seriously insufficient. For this reason, two-way trusses are often used for this type of greenhouse, that is, the greenhouse column tops are used in both the bay and span directions. Truss structure. This structure has fewer indoor columns and larger space.

3. Smart glass greenhouse covering material is glass. Glass as a traditional light-transmitting material, glass is still a commonly used covering material for this smart glass greenhouses in most countries with cold climates. 90% of greenhouses in the Netherlands are covered with glass Ordinary glass used in the construction of glass greenhouses is generally flat glass, usually in two specifications of thickness 4mm and 5mm. In Europe and the United States, 4mm thickness glass is commonly used, and 5mm thickness is only used in hail-prone areas. In China design, glass with a thickness of 5mm meets the requirements of the civil construction market and has become a common specification for glass greenhouse covering. With the gradual increase in imported greenhouses and the increase in investment of foreign glass greenhouse manufacturers in China, 4mm thick glass is gradually used in China’s glass greenhouses.

4. Smart greenhouses generally realize full automation of the planting system. Including water supply system, fertilization system and irrigation system, etc. The equipment that needs to be equipped includes water and fertilizer integrated machines, water tanks, water pipes, etc.
