Description

Technical Field

[0001] This utility model relates to the field of heat-insulating greenhouse technology, specifically a double-layer inflatable light-converting film heat-insulating greenhouse structure. Background Technology

[0002] In the development of modern agriculture, facility agriculture is an important means to improve agricultural production efficiency and ensure a stable supply of agricultural products. Among them, greenhouses, as the core carriers of facility agriculture, have structural design and functional optimization that are directly related to the effect of crop growth environment regulation and energy utilization efficiency.

[0003] Traditional greenhouses mostly use a single layer of plastic film for covering. While this provides basic light transmission and heat insulation, its performance in extreme climates, such as severe winters or high summers, often falls short of the needs of crop growth. Furthermore, the single-layer film structure is susceptible to damage from external forces, leading to a decrease in the stability of the greenhouse's internal environment and consequently affecting crop yield and quality.

[0004] Therefore, in order to address the above issues, the applicant needs to design a double-layer inflatable light-converting film insulation greenhouse structure to solve the problems. Utility Model Content

[0005] The purpose of this invention is to provide a double-layer inflatable light-converting film insulation greenhouse structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-layer inflatable light-converting film heat-insulating greenhouse structure, including a base, with supporting legs fixedly installed below the base, a fixed frame fixedly installed above the base, an arc-shaped frame fixedly installed on the fixed frame, and a composite film installed on the arc-shaped frame. The composite film is configured from the inside out as an inner light-converting film, a middle air chamber layer, and an outer dustproof and aging-resistant film. An air inlet is provided on the composite film, and the air inlet is connected to the middle air chamber layer. An air inflation mechanism is provided above the base, and the air inflation mechanism inflates the middle air chamber layer through the air inlet. The air inflation mechanism includes an air inflator body placed on the base, a connecting hose connected to the air inflator body, and an air inflation head corresponding to the air inlet at the output end of the connecting hose.

[0007] Furthermore, a mounting bracket is fixedly installed above the fixed frame, and a movable door is hinged to the mounting bracket.

[0008] The above structural design facilitates ventilation adjustment and daily entry and exit operations for users, improving the convenience of greenhouse management and the flexibility of internal environmental control.

[0009] Furthermore, a stabilizing base is provided below the inflator body, and a limiting block for clamping the inflator body is fixedly provided on the stabilizing base.

[0010] The above structural design effectively fixes the position of the air inflator, preventing the equipment from shifting or tipping over due to vibration during operation, thus ensuring a stable and reliable inflation process.

[0011] Furthermore, a support beam is fixedly installed on the arc-shaped frame, and the support beam is used to support the composite membrane.

[0012] The above structural design enhances the support strength of the arc frame for the composite film, effectively preventing the film from sinking or deforming due to snow accumulation, strong winds, or inflation pressure, and improving the overall structural stability of the greenhouse.

[0013] Furthermore, the outer dustproof and aging-resistant film is a fluoroplastic film, and the surface of the fluoroplastic film is coated with a silicon oxide / titanium oxide composite dustproof coating.

[0014] The above structural design improves the weather resistance and dustproof performance of the membrane material, extends its service life, and maintains a high light transmittance, avoiding a decrease in light transmittance due to dust accumulation and aging.

[0015] Furthermore, an air chamber diaphragm is provided in the intermediate air chamber layer, and the air chamber diaphragm forms a cross-linked air network by heat sealing.

[0016] Through the above structural design, the intermediate air chamber layer forms a uniform and stable air interlayer after being filled with air, which significantly improves the thermal insulation performance and enhances the overall structural strength and wind pressure resistance of the membrane.

[0017] Furthermore, the inflation network includes parallel straight air columns and perpendicularly intersecting horizontal air columns, with the ends of the straight air columns connected to the air outlets of the inflation ports, and the horizontal air columns connected to the straight air columns.

[0018] Through the above structural design, the airflow distribution is optimized, ensuring uniform inflation of the air chamber without dead zones, thereby improving the stability of the air chamber and the uniformity of the insulation effect.

[0019] Furthermore, the inner light-converting film is a polyethylene substrate, and rare earth organic complex light-converting agent is uniformly dispersed in the substrate.

[0020] Through the above structural design, non-photosynthetically active radiation such as ultraviolet light can be converted into wavelengths such as red and orange light that are beneficial to plant photosynthesis, thereby improving light energy utilization efficiency and promoting crop growth and quality improvement.

[0021] Compared with the prior art, the beneficial effects of this utility model are: This double-layer inflatable light-converting film greenhouse structure forms a highly efficient static air insulation layer through the middle air chamber layer maintained by the inflation mechanism. This improves the heat preservation and insulation performance and greatly reduces energy loss under extreme temperatures. At the same time, the composite membrane structure, reinforced by the supporting beams and the internal inflation network, has excellent pressure resistance, wind resistance, and tear resistance, ensuring the overall building's sturdiness and durability. In addition, the application of fluoroplastic film and dustproof coating ensures the long-term stability of light transmittance, thereby promoting crop growth and quality improvement.

[0022] This double-layered inflatable light-converting film greenhouse structure uses an inner light-converting film to convert ineffective ultraviolet light into visible light that promotes photosynthesis, thus optimizing the light quality inside the greenhouse. This directly provides a better light environment for crop growth, resulting in increased yield and improved quality. The movable door facilitates daily management. All components work together to create a stable growth environment with constant temperature and sufficient light, ultimately achieving comprehensive benefits such as improved energy efficiency, reduced operating costs, and guaranteed high yield and quality of agricultural products.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1-5As shown, this utility model discloses a double-layer inflatable light-converting film heat-insulating greenhouse structure, including a base 1, with a support leg 10 fixedly installed below the base 1, a fixed frame 11 fixedly installed above the base 1, an arc-shaped frame 12 fixedly installed on the fixed frame 11, and a composite film 14 installed on the arc-shaped frame 12. The composite film 14 is configured from the inside out as an inner light-converting film 142, a middle air chamber layer 141, and an outer dustproof and aging-resistant film 140. An air inlet 19 is provided on the composite film 14, and the air inlet 19 is connected to the middle air chamber layer 141. An air inflation mechanism 2 is provided above the base 1, and the air inflation mechanism 2 inflates the middle air chamber layer 141 through the air inlet 19. The air inflation mechanism 2 includes an air inflator body 20 placed on the base 1, a connecting hose 21 connected to the air inflator body 20, and an air inflation head 22 corresponding to the air inlet 19 is provided at the output end of the connecting hose 21.

[0027] An installation frame 15 is fixedly installed above the fixed frame 11, and a movable door 16 is hinged on the installation frame 15. By setting the movable door 16 on the fixed frame 11, it greatly facilitates personnel to enter and exit the greenhouse for agricultural operations, avoids frequent lifting or damage to the sealing structure of the composite film 14, effectively maintains the stability of the temperature, humidity and gas environment inside the greenhouse, reduces heat loss and environmental fluctuations caused by human operation, and thus ensures the continuity and stability of the crop growth environment.

[0028] A stabilizing base 17 is provided below the inflator body 20, and a limiting block 18 for clamping the inflator body 20 is fixedly provided on the stabilizing base 17. Through the cooperation of the stabilizing base 17 and the limiting block 18, the inflator body 20 can be firmly clamped and fixed on the base 1, which effectively prevents the inflator body 20 from shifting or tipping over due to vibration during operation, ensuring the continuity and stability of the inflation process, and ensuring that the intermediate air chamber layer 141 can always maintain the best inflation state.

[0029] A support beam 13 is fixedly installed on the arc-shaped frame 12, and the support beam 13 is used to support the composite film 14. The support beam 13 is fixed on the arc-shaped frame 12, providing an additional intermediate support point for the large-area composite film 14. This can significantly enhance the structural strength of the film surface and effectively prevent the composite film 14 from sinking, deforming, or even breaking due to external forces such as internal inflation pressure, snow accumulation, or strong winds, thereby improving the overall load-bearing capacity and structural safety of the greenhouse.

[0030] The outer dustproof and aging-resistant film 140 is a fluoroplastic film, and the surface of the fluoroplastic film is coated with a silicon oxide / titanium oxide composite dustproof coating. The outer layer uses a highly weather-resistant fluoroplastic film and is coated with a silicon oxide / titanium oxide composite coating, which greatly improves the film material's aging resistance, UV resistance and dustproof performance. Its surface is not easy to powder and degrade, thus extending its service life. At the same time, the smooth coating makes it difficult for dust and raindrops to adhere, and it is easy to be washed away by rainwater. It can maintain high light transmittance for a long time, ensuring that crops receive sufficient and stable light.

[0031] An air chamber membrane is provided in the intermediate air chamber layer 141, and the air chamber membrane forms a cross-linked air network in the horizontal and vertical directions by heat sealing. By setting a cross-linked heat-sealed air network in the intermediate air chamber layer 141, a large chamber is divided into many interconnected small air chamber units, which enhances the structural stability and tear resistance of the air chamber layer. When local damage occurs, it can effectively limit the gas leakage range, prevent the overall collapse of the air chamber, and improve the safety redundancy. At the same time, the supporting effect of the network makes the membrane surface more uniformly stressed.

[0032] The inflation network consists of parallel straight air columns and vertically intersecting horizontal air columns. The ends of the straight air columns are connected to the air outlets of the inflation port 19, and the horizontal air columns are connected to the straight air columns. This clearly defines the inflation network as composed of parallel straight air columns and vertical horizontal air columns, with the straight air columns directly connected to the inflation port 19. This forms an efficient and unobstructed gas flow channel, ensuring that compressed air can be quickly and evenly delivered to every far corner of the air chamber layer, avoiding inflation dead zones, achieving uniform expansion and full support of the entire intermediate layer, and ensuring the best thermal insulation effect.

[0033] The inner light-converting film 142 is made of polyethylene substrate, and rare earth organic complex light-converting agent is uniformly dispersed in the substrate. The rare earth organic complex light-converting agent in the inner light-converting film 142 can convert ultraviolet light in sunlight, which has low photosynthetic efficiency for plants, into usable visible light, optimize the spectral quality in the greenhouse, improve the light energy utilization efficiency, and thus effectively promote the photosynthesis, growth and development of crops.

[0034] When using this double-layer inflatable light-converting film greenhouse structure, the air inflator 20 continuously supplies air to the middle air chamber layer 141 of the composite film 14 through the connecting hose 21 and the air inflator 22 via the air inlet 19, causing it to expand and form a stable air interlayer. This sealed air interlayer has extremely low thermal conductivity, effectively blocking heat loss from the greenhouse and heat transfer from the outside, thus exhibiting excellent heat insulation performance and reducing temperature fluctuations in the greenhouse environment. At the same time, the outer dustproof and aging-resistant film 140 ensures high and long-lasting light transmittance and resists external weathering, while the inner light-converting film 142 converts some ultraviolet light into blue or red light that is beneficial to plant photosynthesis, optimizing the light quality inside the greenhouse. Ultimately, through the synergistic effect of this active inflation forming a static air insulation barrier and spectral regulation, a more constant temperature and better light environment are created for crops, achieving the dual goals of energy saving and increased yield.

[0035] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
