Description

Technical Field

[0001] This utility model relates to the field of agricultural greenhouse structure technology, specifically a vertical transmission drive device for movable greenhouse window sashes. Background Technology

[0002] Greenhouse window sash drive system refers to an electromechanical integrated device used to automatically control the opening and closing of greenhouse ventilation windows (including skylights, side windows, etc.). Its core function is to precisely adjust the opening and closing angle and speed of the windows based on environmental parameters (such as temperature, humidity, and light) or preset instructions, so as to realize intelligent control of the greenhouse environment.

[0003] The rotating shaft of the traditional greenhouse window sash drive system is horizontally arranged on the upper part of the roof, which leads to the following drawbacks: blocking sunlight and reducing light transmittance; occupying roof maintenance space (such as replacing glass); requiring installation through the structure, which is prone to corrosion.

[0004] Based on this, the present invention proposes a vertical transmission drive device for movable windows of greenhouses. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes a vertical transmission drive device for movable greenhouse windows. This device can avoid the roof lighting area by directing the transmission components, thus greatly improving light transmittance. The roof area is unobstructed by equipment, facilitating glass replacement. The clamp-type installation avoids structural perforation and provides corrosion protection. The vertical layout directly transmits wind loads to the columns, improving the stability of the device.

[0006] The technical solution to achieve the purpose of this utility model is: a vertical transmission drive device for movable window sashes in a greenhouse, including a greenhouse, wherein multiple columns are provided inside the greenhouse, multiple crossbeams are fixedly connected to the multiple columns, multiple roofs are respectively provided on the multiple crossbeams, multiple grooves are opened between the multiple roofs, and multiple window frames are slidably connected in the multiple grooves, and further includes;

[0007] An operating component includes a power source, a rotating shaft, and a universal joint. The power source is mounted on a crossbeam, the universal joint is mounted on the power source, and the rotating shaft is mounted on the universal joint. A curtain is located below the operating component. A driver is mounted on the crossbeam. The driver includes a housing and a rack. Multiple housings are fixedly connected to multiple crossbeams, and multiple racks are slidably connected within multiple housings. Multiple control rods are fixedly connected to multiple racks, and multiple extension members are provided on multiple windows.

[0008] Preferably, multiple sliding bearings are fixedly connected to the multiple crossbeams, and the multiple control rods are slidably connected to the multiple sliding bearings.

[0009] Preferably, multiple female couplings are fixedly connected to the multiple rotating shafts, and multiple male couplings are rotatably connected to the multiple housings, with the female couplings being adapted to the male couplings.

[0010] Preferably, the driver further includes a gear ring and a large gear, with multiple gear rings fixedly connected to the multiple male couplings respectively, and multiple large gears rotatably connected to the multiple housings respectively, with the gear rings meshing with the large gears.

[0011] Preferably, the driver further includes pinions, and multiple pinions are fixedly connected to multiple large gears, with the pinions meshing with a rack.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] In this invention, the rotating shaft is vertically arranged directly below the trench, avoiding the obstruction of the roof lighting area by the traditional horizontal shaft. Actual measurements show that it increases the greenhouse light transmittance by ≥15%. The gearbox housing adopts a clamp design to directly clamp the column without drilling, eliminating the risk of structural corrosion at the source. The roof area is completely open, providing unobstructed operating space for glass replacement and equipment maintenance, improving maintenance efficiency by more than 50%. This design simultaneously solves the three major pain points of traditional systems—light loss, perforation and corrosion, and inconvenient maintenance, achieving synergistic optimization of maximizing lighting and maintenance-free operation throughout the entire life cycle.

[0020] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] This utility model provides an improved vertical transmission drive device for movable greenhouse window sashes. The technical solution of this utility model is as follows:

[0022] like Figures 1-3 As shown, a vertical transmission drive device for movable window sashes in a greenhouse includes a greenhouse 1, a plurality of columns 2 inside the greenhouse 1, a plurality of crossbeams 3 fixedly connected to the plurality of columns 2, a plurality of roofs 4 respectively on the plurality of crossbeams 3, a plurality of grooves 5 opened between the plurality of roofs 4, a plurality of window 6 slidably connected in the plurality of grooves 5, the window 6 being used to adjust the ventilation inside the greenhouse 1, and also includes;

[0023] The operating component 7 includes a power source 8, a rotating shaft 9, and a universal joint 10. The power source 8 is mounted on the crossbeam 3, the universal joint 10 is mounted on the power source 8, and the rotating shaft 9 is mounted on the universal joint 10. A curtain 22 is located below the operating component 7, and a driver 11 is mounted on the crossbeam 3. The driver 11 includes a housing 15 and a rack 16. Multiple housings 15 are fixedly connected to multiple crossbeams 3, and multiple racks 16 are slidably connected to multiple housings 15. Multiple control rods 12 are fixedly connected to multiple control rods 12, and multiple extension members 13 are provided on multiple windows 6. The rotational motion is efficiently converted into the linear thrust of the rack 16, increasing the torque output by three times. The control rods 12 are synchronously linked to multiple windows 6 through the extension members 13, eliminating the risk of end-point asynchrony. The driver achieves high precision and reliable drive resistant to extreme weather with a purely mechanical structure.

[0024] Furthermore, such as Figure 1 and Figure 2 As shown, multiple sliding bearings 14 are fixedly connected to multiple crossbeams 3 respectively, and multiple control rods 12 are slidably connected to multiple sliding bearings 14 respectively. The sliding bearings 14 reduce the friction when the control rods 12 move and limit the control rods 12 to ensure stable movement.

[0025] Furthermore, such as Figure 2 As shown, multiple female couplings 20 are fixedly connected to multiple rotating shafts 9, and multiple male couplings 21 are rotatably connected to multiple housings 15. The female couplings 20 and male couplings 21 are adapted to each other. The female couplings 20 and male couplings 21 adopt a sliding plug-in structure to support rapid networking of multiple units.

[0026] Furthermore, such as Figure 2 and Figure 3 As shown, the driver 11 also includes a gear ring 17 and a large gear 18. Multiple gear rings 17 are fixedly connected to multiple male couplings 21 respectively, and multiple large gears 18 are rotatably connected to multiple housings 15 respectively. The gear rings 17 mesh with the large gears 18, and drive the large gears 18 to rotate through the gear rings 17.

[0027] Furthermore, such as Figure 2 and Figure 3 As shown, the driver 11 also includes a pinion 19, which is fixedly connected to a plurality of large gears 18. The pinion 19 meshes with the rack 16. The pinion 19 rotates as the large gear 18 rotates, which drives the rack 16 to move and pushes the control lever 12 to move, thus adjusting the position of the window 6.

[0028] The specific working method is as follows: After the power source 8 is started, it drives the universal joint 10, which in turn drives the rotating shaft 9, which is vertically installed below the groove 5, to rotate. The rotating shaft 9 transmits torque to the gear ring 17 of the rack and pinion drive 11 through the female coupling 20 and the male coupling 21. After three-stage reduction by the large gear 18 and the small gear 19, the rotational motion is converted into the horizontal linear motion of the rack 16. The rack 16 pushes the control rod 12 to move along the direction of the crossbeam 3. The control rod 12 simultaneously pulls multiple window sashes to perform opening and closing actions through the extension member 13: when the control rod 12 moves outward, the extension member 13 extends to push open the window sash; when it retracts, the extension member 13 folds to close the window sash. If local adjustment is required, the corresponding drive 11 can be operated independently to achieve single window control. When the window sash is subjected to strong wind load, the vertical rotating shaft 9 directly transmits the force to the column 2 to avoid deformation of the roof 4 structure. In daily maintenance, the clamp-fixed housing 15 can be quickly disassembled, and the roof 4 is unobstructed by equipment, which facilitates glass replacement work. The system achieves high-precision synchronous control of the window sashes through a mechanical linkage of vertical transmission, gear conversion, and parallel push rods, while avoiding the four lighting zones of the roof (actually improving light transmittance by ≥15%), thus balancing lighting optimization and structural stability.

[0029] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
