Description

Technical Field

[0001] This utility model relates to the field of greenhouse window technology, specifically to a vertical lifting window for wet curtains. Background Technology

[0002] In modern greenhouse farming, evaporative cooling pads are crucial for regulating indoor temperature and humidity. Current technology commonly employs outward-opening window structures, where the window hinges at the bottom to open outwards. This structure has significant drawbacks: a floor-mounted transmission mechanism is required at the bottom of the window, necessitating the construction of concrete foundation pillars to support the window's weight and wind loads. This not only significantly increases construction costs but also occupies a large amount of planting space, leading to reduced land utilization.

[0003] Further research indicates that the maximum opening angle of such outward-folding windows is typically limited to approximately 30 degrees. This opening angle severely restricts ventilation efficiency and fails to meet the full ventilation requirements of aquaculture spaces in high-temperature and high-humidity environments. Especially when evaporative cooling pads are used in conjunction with windows, insufficient window opening directly obstructs airflow across the surface of the evaporative cooling pads, weakening the evaporative cooling effect and impacting the precision of environmental control in aquaculture production.

[0004] To address the aforementioned issues, there is an urgent need to develop a new type of evaporative cooling pad window structure. An ideal solution should meet three requirements: first, eliminate foundation columns to reduce costs and save space; second, allow the window to fully open to maximize ventilation; and third, maintain a reliable connection with the transmission system. Although the industry has attempted improvements such as sliding windows, problems such as poor sealing, asynchronous transmission, or structural deformation still exist, and a fundamental breakthrough has not yet been achieved.

[0011] Furthermore, the aluminum alloy window frame is cut and spliced ​​at 45 degrees at its four corners, and sealing strips are installed at the splices to form a sealing structure; the upper and lower splicing interfaces of the aluminum alloy window frame are staggered.

[0012] Furthermore, the rack has a spacing of 1.6 meters between its two ends and 1.8 meters in the middle; the installation distance between the lifting window frame and the greenhouse facade glass wall is 3 mm.

[0042] According to an embodiment of the present invention, a vertical lifting window for wet curtains is provided. In a specific embodiment, the window frame 10 is made of all-aluminum alloy; the spacing between adjacent gears 7 is 1.6-2 meters; and the drive shaft 9 is a ∅32×3mm round tube.

[0043] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.

[0044] In practical use, the evaporative cooling curtain vertical lifting window described in this utility model adopts a specially developed all-aluminum alloy window frame 10 with a special sealing strip 18, which is easy to assemble, integrally molded, tightly sealed, lightweight and durable. The aluminum alloy window frame 10 can be perfectly connected to the transmission system, which drives the entire aluminum alloy window to slide up and down.

[0045] A single aluminum alloy window frame is typically 1-2 meters wide, suitable for wet curtain heights of 1-2 meters, and generally within 60 meters in length. It is covered with 8-10mm thick PC board 15, and the width of the PC board 15 is divided into 0.8-1 meters using upper H-clamp profile 13 and lower H-clamp profile 14. The entire window frame is stable and reliable, and is not affected by mechanical transmission.

[0046] The vertical window is driven by a transmission system consisting of gears 7, racks 9, a reduction motor 6, and a drive shaft 9. The reduction motor 6 is fixed to the greenhouse column 3 via a motor mounting plate 21, and the gears 7 are fixed to the greenhouse column 3 via a gear mounting plate 20. The gear spacing of the gears 7 is 1.6-2 meters. The reduction motor 6 and gears 7 are connected by the drive shaft 9, which is a ∅32*3 round tube. Each gear 7 is connected to a rack 9, and the rack 9 is connected to the window frame. The torque of the reduction motor 6 is converted into the force of the rack 9 moving up and down, thereby driving the aluminum alloy window frame to move up and down. The transmission is stable and reliable.

[0047] During installation, the four corners of the lifting window frame 12 are cut at 45 degrees and spliced ​​using rivets 23 and splicing plates 31, or rivets 23, flat corner connectors 24, and corner connectors 25. When splicing the upper and lower window frames of the lifting window frame 12, the upper and lower interfaces should be staggered. The window sash uses 8mm polycarbonate sheet. The lifting window frame 12 is connected using rivets 23. The lifting window frame 12 is very close to the glass wall facade, with a spacing of approximately 3mm. The reduction motor 6 is installed in the middle of the window sash and fixed to the greenhouse column 3; a piece of wet curtain paper needs to be removed during installation. The gears 7 are spaced 1.8 meters apart and fixed to the greenhouse column 3 using gear mounting plates 20; fine adjustments are possible during installation. The racks 8 are 1.6m at both ends and 1.8m apart in the middle; they are cut and drilled on-site and used as vertical supports fixed to the lifting window frame 12. When installing the transmission system of the lifting window, the reduction motor 6 and gears 7 should avoid collision with the lifting window frame 12, and their dimensions should be finely adjusted.

[0048] In summary, by utilizing the above-mentioned technical solution of this utility model, and through the optimized and improved design of the vertical sliding structure of the window, the window can be fully opened to the maximum ventilation area, thereby significantly increasing the ventilation volume. The integrated installation method of the transmission system and the greenhouse columns eliminates the need for foundation column construction, thus reducing costs and saving planting space. The modular design of the aluminum alloy window frame combined with the sealing strip gives the window both the advantages of being lightweight and durable as well as having a tight seal. The precise meshing structure of the transmission gear rack and pinion achieves the comprehensive benefits of stable operation and extended maintenance-free cycle.
