[0020] 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.

[0021] Please see Figures 1-7This utility model provides a technical solution: a sterile greenhouse, comprising a greenhouse side section 1 and a greenhouse top section 2. The greenhouse, consisting of the greenhouse side section 1 and the greenhouse top section 2, is 24m long and 16m wide. The foundation is a reinforced concrete foundation with a cement floor, and the main structure is a light steel frame. The greenhouse ridge is 8m high, and the internal ceiling is 7.2m high. The greenhouse side section 1 consists of several columns 101, wind-resistant columns 102, surrounding beams 103, and hollow tempered glass modules 104. The columns 101 and wind-resistant columns 102 are connected by surrounding beams 103 and jointly support the hollow tempered glass modules 104. The greenhouse top section 2 consists of A-frame beams 201, polycarbonate panels 202, and top windows 203. The top of the greenhouse top section 2 is also equipped with external sunshade columns 501 and external sunshade horizontal beams. The external shading net support structure 5, composed of beams 502, and several sets of cooling wet curtains 3 and fans 4 are respectively installed on both sides of the greenhouse side 1. The columns 101 and wind-resistant columns 102 of this structure are stably connected by the surrounding beams 103, which not only enhances the stability of the overall structure, but also effectively supports the hollow tempered glass modules 104, ensuring the high transparency and durability of the greenhouse side 1, which is conducive to maximizing the use of natural light and promoting plant growth. The design of the A-frame beams 201 and polycarbonate panels 202 on the greenhouse roof 2, together with the top windows 203, enables good ventilation inside the greenhouse. The external shading net support structure 5, composed of external shading columns 501 and external shading beams 502, can be flexibly adjusted according to different seasons and weather conditions. Light intensity and temperature create a suitable environment for plant growth. The cooling pads 3 and fans 4 installed on both sides of the greenhouse work in tandem. The cooling pads 3 cool the air entering the greenhouse, and the fans 4 evenly distribute the filtered and cooled fresh air to every corner of the greenhouse, ensuring air quality and improving plant growth efficiency. Overall, the efficient linkage between these components not only optimizes the greenhouse's space utilization, enabling multi-layer planting and increasing planting density and yield, but also simplifies equipment installation and maintenance. It solves the problems of inconvenient operation, low space utilization, and complex equipment installation caused by unreasonable structural design in existing technologies, thus meeting the demands of modern agriculture for high efficiency. To meet the needs of intensive production, the greenhouse is equipped with dedicated entrances and exits, external porch passages, and double-layered safety doors. It also features air showers, disinfection facilities, and air purification equipment. The freight entrance and exit are similarly equipped with external passages and double-layered safety doors, and ozone disinfection facilities to ensure that no pathogens are introduced when goods enter. Irrigation water is treated with a purification system. The inner sides of the greenhouse's side 1 are equipped with side insulation layers 105 via a lifting mechanism. This lifting mechanism includes components such as a motor, rollers, and steel cables, which work together to smoothly raise or lower the side insulation layers 105. The top of the greenhouse 2 is connected to the roof insulation layer 204 via an automatic opening and closing mechanism, which may include a motor-driven track system.Enable the ceiling insulation layer 204 to roll smoothly on the track, achieving a quick-response opening and closing operation. This structure's lifting mechanism can automatically adjust the height of the side insulation layer 105 according to the change of the external environmental temperature, ensuring that in cold seasons or at night, the side insulation layer 105 can be fully lowered to reduce heat loss, while in warm weather, it can be raised to increase air circulation and natural light. Meanwhile, the automatic opening and closing mechanism controls the opening and closing state of the ceiling insulation layer 204 to achieve precise regulation of the temperature inside the greenhouse. The connection between the external sunshade column 501 and the external sunshade crossbeam 502 is fixedly connected by a rod-end connector 503 with a "Ji" - shaped structure and bolts. And a longitudinal rod 504 passes through the lower part of the connection of the rod-end connector 503 of the external sunshade column 501. On both sides of the external sunshade column 501 and the longitudinal rod 504, there are respectively connected a "Ji" - shaped connecting plate 505 and a rectangular connecting plate 506, and the "Ji" - shaped connecting plate 505 and the rectangular connecting plate 506 are also connected to the longitudinal rod 504 by bolts. This structure's rod-end connector 503 firmly connects the external sunshade column 501 and the external sunshade crossbeam 502 together, not only enhancing the rigidity and stability of the overall structure but also effectively dispersing the lateral pressure brought by the external wind force. At the same time, the longitudinal rod 504 is closely connected with it through the "Ji" - shaped connecting plate 505 and the rectangular connecting plate 506, further strengthening the integrity of the structure. The "Ji" - shaped connecting plate 505 and the rectangular connecting plate 506 make the connection points more firm, preventing displacement or loosening under external forces, ensuring the stability and durability of the external sunshade system. In this way, the overall strength and wind resistance of the external sunshade net support structure 5 are improved, providing an ideal shading effect inside the greenhouse. On one side outside the greenhouse side 1, there is a water supply pool 6, and the cooling wet curtain 3 is connected to the water pump inside the water supply pool 6 through a water supply pipe 301. And a return water pipe 302 is also provided at the bottom of the cooling wet curtain 3. This structure's water pump in the water supply pool 6 transports water to the cooling wet curtain 3 through the water supply pipe 301, making the water evenly distributed on the surface of the cooling wet curtain 3. When the external air passes through the cooling wet curtain 3, the heat in the air is absorbed and evaporated by the water, thus achieving effective cooling of the air entering the greenhouse. Subsequently, the water flow passing through the cooling wet curtain 3 returns to the water supply pool 6 through the return water pipe 302 arranged at the bottom, forming a closed circulation system. This design not only ensures that the cooling wet curtain 3 can work continuously and effectively, reducing water resource waste, but also guarantees the cooling effect of the cooling wet curtain 3. There are a total of 5 groups of cooling wet curtains 3 on one side of the greenhouse side 1, each group of the cooling wet curtain 3 is 20.0 m long, and there are a total of 3 fans 4 on the other side of the greenhouse side 1. A dust-proof net is installed in the ventilation window of the fan 4. This structure forms an efficient air circulation system between the cooling wet curtain 3 and the fan 4. When the external hot air passes through the cooling wet curtain 3, the fan 4 starts, blowing the fresh air after cooling evenly to every corner inside the greenhouse. The dust-proof net installed in the ventilation window of the fan 4 effectively filters the dust and impurities in the air, ensuring the air quality entering the greenhouse.This not only significantly reduces the temperature inside the greenhouse, providing a more suitable environment for plant growth, but also achieves optimal airflow through the rationally arranged positions of the cooling evaporative cooling pads 3 and fans 4, improving the efficiency of the entire system. The cooling evaporative cooling pads 3 are installed on the side 1 of the greenhouse via a fixed frame. The fixed frame connected to the cooling evaporative cooling pads 3 is connected to the columns 101 and wind-resistant columns 102 via angle brackets. This structure provides a stable support foundation for the cooling evaporative cooling pads 3, ensuring stability during long-term operation without displacement or deformation. The angle brackets, as key connectors, firmly connect the fixed frame to the columns 101 and wind-resistant columns 102, enhancing the rigidity and stability of the entire structure. This allows the cooling evaporative cooling pads 3 to withstand various forces from the external environment, such as wind pressure. This not only ensures the normal operation of the cooling evaporative cooling pads 3, but also improves the safety and durability of the overall greenhouse structure through effective integration with the columns 101 and wind-resistant columns 102.

[0022] Working Principle: When using this sterile greenhouse, water is first pumped from the water supply tank 6 through the water supply pipe 301 to the cooling pad 3, ensuring even distribution of moisture on the surface of the cooling pad 3. Simultaneously, the motor activates the lifting mechanism, adjusting the height of the side insulation layer 105 according to the ambient temperature. This ensures the side insulation layer 105 is fully lowered during cold seasons or at night to reduce heat loss, and raised during warm weather to increase air circulation and natural light. Then, when hot outside air passes through the cooling pad 3, the heat in the air is absorbed and evaporated by the moisture, effectively cooling the air entering the greenhouse. The cooled, fresh air is then drawn in by the fan 4 and filtered through dust filters installed in its ventilation windows before being evenly blown into various parts of the greenhouse. In this process, the automatic opening and closing mechanism controls the opening and closing state of the roof insulation layer 204, adjusting the temperature inside the greenhouse as needed. The external shading column 501 and the external shading beam 502 are firmly connected by the rod end connector 503, and together with the longitudinal rod 504, the Z-shaped connecting plate 505 and the rectangular connecting plate 506, ensure the stable operation of the external shading system and provide an ideal shading effect. Finally, the water flowing through the cooling wet curtain 3 returns to the water supply tank 6 through the return water pipe 302 set at the bottom, forming a closed circulation system, ensuring that the cooling wet curtain 3 can work continuously and effectively. The entire system works in concert, and through the precise control of these components, the optimal management of the greenhouse internal environment is achieved, providing a suitable growth condition for the plants, thereby completing a series of tasks.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
