Abstract
Description
Technical Field
[0001] This utility model relates to the field of greenhouse technology, specifically a greenhouse based on internal and external frame auxiliary support. Background Technology
[0002] A greenhouse, also known as a hothouse, is an agricultural facility specifically designed for plant cultivation. It utilizes light-transmitting materials such as glass and plastic film as a covering to create a relatively enclosed yet well-lit space, providing plants with a stable and suitable microclimate for growth. During seasons with low temperatures or other unfavorable conditions for plant growth, the greenhouse acts as a cradle for life, extending the growing season and effectively increasing crop yields. This facility is widely used in the cultivation and seedling raising of heat-loving vegetables, flowers, and trees. Greenhouses not only have good light transmission but also excellent heat retention (or heating) and durability. With the help of intelligent control systems, environmental factors such as light, temperature, and humidity can be precisely controlled to meet the personalized growth needs of various crops, making off-season production possible and greatly improving crop yield and quality. However, the combination and construction of traditional enclosed greenhouses is cumbersome and laborious, and the ventilation method is limited. Relying solely on doors or hanging windows makes it difficult to flexibly control the degree of openness of the internal space, which to some extent limits its ease of use and ventilation effect. Existing technologies may already have solutions to the above problems, but this case aims to provide an alternative or replacement technical solution. Utility Model Content
[0003] To achieve the above objectives, this utility model provides the following technical solution: a greenhouse based on auxiliary support of inner and outer frames, comprising: an inner secondary steel frame, an outer steel frame, and a pair of rear steel frames. The inner secondary steel frames are connected to the pair of rear steel frames, and the outer steel frames are connected to the rear steel frames. A lifting window control structure is installed on the outer steel frame. The lifting window control structure comprises: several outer steel combination buckles, several inner steel combination buckles, several rear steel combination buckles, a light-blocking and heat-insulating curtain, a pair of window mechanism mounting brackets, a mechanism platform, a lifting motor, a pair of lifting modules, a pair of transmission links, a skylight mounting block, a roof skylight, and symmetrical screws.
[0004] A plurality of outer steel combination buckles are respectively installed on the outer steel frame, a plurality of inner steel combination buckles are respectively installed on the inner secondary steel frame, a plurality of rear steel combination buckles are respectively installed on a pair of rear steel frames, the light-blocking and heat-insulating curtain is installed on the inner secondary steel frame, a pair of awning mechanism mounting brackets are respectively installed on a pair of outer steel combination buckles, and the pair of awning mechanism mounting brackets are respectively connected to the mechanism platform, the lifting motor is installed on the mechanism platform, the lifting motor is connected to the symmetrical screw, and the mechanism platform... A modular connecting slide is provided, and a pair of lifting modules are respectively connected to the mechanism platform through the modular connecting slide. The pair of lifting modules are respectively mounted on the symmetrical screws. A pair of transmission connecting rods are respectively mounted on the pair of lifting modules through rotating shafts, and the pair of transmission connecting rods are respectively connected to the skylight mounting block through rotating shafts. The skylight is mounted on the skylight mounting block. The inner secondary steel frame, the outer steel frame, and a pair of rear steel frames are respectively connected to the color steel wall panel. The door and exit components are installed on the color steel wall panel.
[0005] It should be noted that, as described above, the inner secondary steel frame, outer steel frame, and a pair of rear steel frames are first erected using ground stakes and stakes, along with plastic steel ropes, to form an integrated support structure. Then, multiple support structures are erected sequentially as needed. Next, a polyolefin (PO) film or polyvinyl chloride (PVC) greenhouse film is fitted onto the outer side. Finally, color steel wall panels are installed on both sides of the frame, completing the greenhouse structure. It is particularly important to note that the outer steel frame can be connected with multiple outer steel combination buckles to assemble a single type of greenhouse film, and the inner secondary steel frame can be connected with multiple inner steel combination buckles to assemble a single type of greenhouse film, thereby enriching and enhancing the greenhouse's functionality and effectiveness. The rear steel combination buckles are responsible for connecting and securing the rear steel frame to other film components. In addition to other expansion accessories (such as hooks), the canopy window mechanism mounting bracket can be unfolded on the inner secondary steel frame as needed. Therefore, this canopy is suitable for cultivating vegetation that needs to be shaded or requires strong light at the same time, and can be enhanced to keep the temperature higher at night when stronger heat preservation is needed. When the canopy needs ventilation, the lifting motor on the drive mechanism platform is activated, which drives the symmetrical screw to rotate, thereby causing a pair of lifting modules to move closer or further apart, which in turn drives the transmission linkage to lift or lower the skylight mounting block and the canopy skylight, thereby controlling the opening size of the canopy skylight. The mechanism platform is suspended and fixed by a pair of canopy window mechanism mounting brackets, and the dust cover on the lifting motor can protect the lifting motor from dust.
[0006] Preferably, the door and exit assembly includes: a side door, a main door, a first mounting plate, a second mounting plate, a limiting bolt, a limiting hook frame, a hook frame pivot, an extension block, a hook frame magnet, and a support block magnet.
[0007] The side opening door is installed on the color steel wall panel, the main opening door is installed on the color steel wall panel, the second mounting plate is installed on the main opening door, the first mounting plate is installed on the side opening door, the limiting bolt is installed on the second mounting plate, the limiting hook frame is connected to the hook frame pivot, the hook frame pivot is installed on the extension support block, the extension support block is installed on the first mounting plate, the hook frame magnet is installed on the limiting hook frame, and the support block magnet is installed on the extension support block;
[0008] It should be noted that, as described above, the main door can be opened and closed via a handle, while the side doors can be individually locked or unlocked via latches, thus increasing the overall openness of the shed. Once the latches are locked, only the main door can be opened and closed, allowing for adjustment of the overall openness of the shed. The accessories on the first and second mounting plates automatically lock both the main and side doors, preventing temperature loss due to incomplete door closure. When the main door closes, the limit bolt will first contact the limit hook frame, which will push the limit hook frame to rotate slightly on the hook frame pivot until it slides into the groove on the limit hook frame. The limit hook frame then resets. At this time, the limit bolt is fixed by the frame sleeve, so it is not easy to separate the side door from the main door and complete the locking. When real-time automatic locking is not required, the limit hook frame only needs to be fully attached to the extension block. At this time, the magnet of the support block and the magnet of the hook frame will attract each other and fix them through magnetic force. Then the limit bolt loses the constraint of the limit hook frame, and the side door and the main door can open and close freely.
[0009] Preferably, the lifting motor is equipped with a dust cover;
[0010] Preferably, the limiting bolt is provided with a wear-resistant coating;
[0011] Preferably, the main door is provided with a door handle;
[0012] Preferably, the side-opening door is equipped with a door latch.

Furthermore, by precisely controlling the lifting range of the skylights, it achieves fine control of air exchange, ensuring both good heat preservation and adequate air circulation when necessary.

Steel combination buckles 4 are respectively installed on the outer steel frame 2, several inner steel combination buckles 5 are respectively installed on the inner secondary steel frame 1, several rear steel combination buckles 6 are respectively installed on a pair of rear steel frames 3, the light-blocking and heat-insulating curtain 7 is installed on the inner secondary steel frame 1, a pair of awning mechanism mounting brackets 8 are respectively installed on a pair of outer steel combination buckles 4, and the pair of awning mechanism mounting brackets 8 are respectively connected to the mechanism platform 9, the lifting motor 10 is installed on the mechanism platform 9, the lifting motor 10 is connected to the symmetrical screw 15, the mechanism platform 9 is provided with a module connecting slide groove, and a pair of lifting modules 11 are respectively connected to the mechanism platform 9 through the module connecting slide groove. The mechanism platform 9 is connected to each other, and a pair of lifting modules 11 are respectively mounted on the symmetrical screws 15. A pair of transmission connecting rods 12 are respectively mounted on the pair of lifting modules 11 through rotating shafts, and the pair of transmission connecting rods 12 are respectively connected to the skylight mounting block 13 through rotating shafts. The skylight 14 is mounted on the skylight mounting block 13. The inner secondary steel frame 1, the outer steel frame 2, and a pair of rear steel frames 3 are respectively connected to the color steel wall panel. The color steel wall panel is equipped with an entrance / exit assembly. The entrance / exit assembly includes: a side opening door 16, a main opening door 17, a first mounting plate 18, a second mounting plate 19, a limit bolt 20, a limit hook frame 21, and a hook frame rotating shaft. 22. Extension support block 23, hook frame magnet 24, and support block magnet 25; the side opening door 16 is installed on the color steel wall panel, the main opening door 17 is installed on the color steel wall panel, the second mounting plate 19 is installed on the main opening door 17, the first mounting plate 18 is installed on the side opening door 16, the limiting bolt 20 is installed on the second mounting plate 19, the limiting hook frame 21 is connected to the hook frame rotating shaft 22, the hook frame rotating shaft 22 is installed on the extension support block 23, the extension support block 23 is installed on the first mounting plate 18, the hook frame magnet 24 is installed on the limiting hook frame 21, and the support block magnet 25 is installed on the extension support block 23.
[0024] According to the appendix Figure 1-4The process involves first erecting the inner secondary steel frame 1, outer steel frame 2, and a pair of rear steel frames 3 using ground piles and stakes, along with plastic steel ropes, to form a unified support structure. Then, multiple support structures are erected sequentially as needed. Next, polyolefin (PO) film or polyvinyl chloride (PVC) film is fitted onto the outer side. Finally, color steel wall panels are installed on both sides of the frame, completing the greenhouse assembly. It's important to note that the outer steel frame 2 can be connected with multiple outer steel combination buckles 4 to assemble a single type of greenhouse film, and the inner secondary steel frame 1 can be connected with multiple inner steel combination buckles 5 to assemble a single type of greenhouse film, thus enriching and enhancing the greenhouse's functionality and effectiveness. The rear steel combination buckles 6 are responsible for connection and fixation. The rear steel frame 3, along with other membrane bodies and other extension accessories (such as hooks), and the canopy window mechanism mounting bracket 8 can be deployed on the inner secondary steel frame 1 as needed. This allows the greenhouse to simultaneously cultivate vegetation requiring shade or strong light, and to enhance insulation when stronger insulation is needed at night. When ventilation is required, the lifting motor 10 on the drive mechanism platform 9 rotates the symmetrical screw 15, causing a pair of lifting modules 11 to move closer or further apart. This, in turn, drives the transmission linkage 12, raising or lowering the skylight mounting block 13 and the canopy skylight 14, thus controlling the opening size of the canopy skylight 14. The mechanism platform 9, through a pair of canopy window mechanism mounting brackets... The support bracket 8 is suspended and fixed, while the dust cover on the lifting motor 10 provides dust protection. The main opening and closing door 17 can be opened, closed, and locked via a handle, while the side opening and closing door 16 can be locked or opened independently, increasing the overall openness of the shed. Once the door latch is locked, only the main opening and closing door 17 can be opened and closed, allowing for adjustment of the overall openness of the shed. The accessories on the first mounting plate 18 and the second mounting plate 19 automatically lock the main opening and closing door 17 and the side opening and closing door 16, preventing incomplete closure and potential damage. In the event of a temperature drop, when the main door 17 is closed, the limit bolt 20 will first contact the limit hook frame 21, thereby pushing the limit hook frame 21 to rotate slightly based on the hook frame pivot 22 until it slides into the groove on the limit hook frame 21. The limit hook frame 21 then resets. At this time, the limit bolt 20 is fixed by the frame, making it difficult to easily separate the side door 16 from the main door 17 and complete the locking. When real-time automatic locking is not required, the limit hook frame 21 only needs to be fully attached to the extension block 23. At this time, the block magnet 25 and the hook frame magnet 24 will attract and fix each other through magnetic force, and the limit bolt 20 will lose the constraint of the limit hook frame 21. At this time, the side door 16 and the main door 17 can open and close freely.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
