Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, specifically to a ventilation structure for a glass greenhouse. Background Technology

[0002] Greenhouses are widely used for the cultivation or seedling raising of vegetables, flowers, trees and other plants because they have the advantages of regulating environmental conditions such as temperature, humidity and light, and can withstand natural disasters such as wind, rain, hail and frost, thus meeting the diverse needs of the market.

[0003] Greenhouses mainly include plastic greenhouses and glass greenhouses. Except for their lower cost, plastic greenhouses are far inferior to glass greenhouses in other aspects. The smooth surface of glass results in low light scattering and more uniform light distribution inside, reducing uneven growth of crops caused by light differences.

[0004] Glass greenhouses are further divided into ordinary glass greenhouses and double-glazed greenhouses. The heat transfer coefficient of double-glazed glass is as low as 2.0-3.0 W / (㎡·K), which is lower than the heat transfer coefficient of single-glazed glass of 5.0 W / (㎡·K). In winter, it can reduce heat loss and reduce heating energy consumption. In summer, with the help of external shading systems (shading rate of 70%-80%) and ventilation equipment, the indoor temperature can be effectively controlled and high temperature stress can be avoided.

[0005] In traditional glass greenhouses, windows often employ a single-pane or double-pane design with opposing openings. Ventilation is controlled by adjusting the opening angle of each window, resulting in a limited adjustable range and difficulty in controlling the ventilation volume. This leads to uneven ventilation and poor convection. Furthermore, the single-window adjustment method in traditional greenhouses only creates an air buffer layer by controlling the opening angle of each window, and the airflow path is singular, making it impossible to achieve gradient ventilation through mechanical linkage. Additionally, the uneven airflow distribution within the internal circulation system of traditional glass greenhouses easily creates dead zones or excessive wind speeds. Dead zones are prone to temperature and humidity imbalances, while areas with excessive wind speeds cause leaf tearing and stem lodging, affecting the uniformity and health of crop growth.

[0008] Preferably, both the first ventilation duct and the third ventilation duct include multiple fans, wherein the ventilation direction of the fans in the first ventilation duct is opposite to that of the fans in the third ventilation duct.

[0009] Preferably, the top multi-window linkage ventilation structure includes: a first multi-window linkage structure and a first fan; the first multi-window linkage structure and the first fan cooperate for top ventilation of the glass greenhouse; wherein, the first multi-window linkage structure is installed on the top of the glass greenhouse; the first fan is installed on the glass greenhouse and is located below the first multi-window linkage structure.

[0012] Preferably, the main frame assembly includes: a main frame, a first window connector, and a second window connector; the main frame is provided with multiple installation units, the number of which is equal to the number of ventilation window assemblies; there are two first window connectors, which are respectively installed at both ends of the main frame for the main frame to be openably and closably installed on the glass greenhouse; there are multiple second window connectors, the number of which matches the number of installation units, and the multiple second window connectors are respectively installed in multiple installation units; the ventilation window assemblies are openably and closably installed on the installation units through the second window connectors.

[0016] Compared with the closest existing technology, the beneficial effects of this utility model are as follows:

[0017] 1. The zoned design of the top and side ventilation modules of this utility model significantly improves the ventilation efficiency and environmental control flexibility of the glass greenhouse. The multi-window linkage structure at the top can use the thermal pressure effect to preferentially exhaust the high-temperature air at the top, quickly reduce the heat accumulation at the top, and avoid crops from suffering high-temperature stress. The side structure introduces fresh air from the outside, promotes airflow circulation at the bottom, regulates humidity, and replenishes carbon dioxide. The two work together to form a three-dimensional air convection, optimize the ventilation path, and eliminate dead airflow corners in the greenhouse.

[0018] 2. The first and third ventilation ducts of this utility model work together to stratify the airflow. The second ventilation duct, in conjunction with the first and third ventilation ducts, can form a composite airflow field in both horizontal and vertical directions. By adjusting the wind speed of different ducts, the lateral diffusion and longitudinal disturbance of greenhouse air are promoted, breaking the dead zone of airflow that is easily formed by traditional single top ventilation ducts. At the same time, both the first and third ventilation ducts use multiple fans to work together, avoiding temperature and humidity imbalances or concentrated wind speed exceeding limits in local areas due to airflow stagnation, thus providing a more stable microenvironment for large-scale planting.

[0019] 3. The present invention provides multiple ventilation window assemblies, each of which can be opened and closed and installed on the main frame assembly. This means that each ventilation window assembly can control ventilation. The amount of ventilation can be controlled by controlling the number of ventilation windows in the assembly. This not only makes it easier to control the amount of ventilation, but also increases the adjustable range of ventilation, thus solving the problems of uneven ventilation and poor convection.

[0020] 4. The first window connector, the second window connector, and the third window connector of this utility model are all remotely controlled by a wireless control system, which enables the opening and closing angle of each ventilation window group to be remotely controlled. This not only increases the control accuracy, but also optimizes the airflow path and achieves gradient ventilation by controlling the opening and closing angle of different ventilation window groups.

[0021] 5. The main frame assembly of this utility model can open all ventilation window assemblies simultaneously, directly controlling them to reach the maximum ventilation volume requirement without adjusting each window assembly individually, simplifying the operation process, and achieving maximum air replacement in the shortest time, greatly increasing ventilation efficiency.

[0033] Example 1

[0034] like Figures 1-8As shown, this utility model provides a ventilation structure for a glass greenhouse, including: an internal circulation ventilation structure 2, a top multi-window linkage ventilation structure 3, and a side multi-window linkage ventilation structure 4. The internal circulation ventilation structure 2 is installed inside the glass greenhouse 1 for internal circulation ventilation of the glass greenhouse 1; the top multi-window linkage ventilation structure 3 is installed on the top of the glass greenhouse 1 for top ventilation of the glass greenhouse 1; and the side multi-window linkage ventilation structure 4 is installed on the side of the glass greenhouse 1 for side ventilation of the glass greenhouse 1. The zoned design of the top and side ventilation modules significantly improves the ventilation efficiency and environmental control flexibility of the glass greenhouse. The top multi-window linkage structure can utilize the thermal pressure effect to preferentially exhaust the high-temperature air from the upper layer, quickly reducing the heat accumulation at the top and preventing crops from suffering from high-temperature stress. The side structure introduces fresh external air, promotes airflow circulation at the bottom, regulates humidity, and replenishes carbon dioxide. The two work together to form a three-dimensional air convection, optimizing the ventilation path and eliminating dead air zones in the greenhouse.

[0035] In a preferred embodiment, the internal circulation ventilation structure 2 includes: a first ventilation duct 21, a second ventilation duct 22, and a third ventilation duct 23; the first and second ventilation ducts 21 and 22 are both installed at the top of the inner side of the glass greenhouse 1; the third ventilation duct 23 is installed at the bottom of the inner side of the glass greenhouse 1. Preferably, both the first and third ventilation ducts 21 and 23 include multiple fans, wherein the ventilation direction of the fans in the first ventilation duct 21 is opposite to that in the third ventilation duct 23. The first and third ventilation ducts work together to stratify the airflow. The second ventilation duct, in conjunction with the first and third ventilation ducts, can form a composite airflow field in both horizontal and vertical directions. By adjusting the wind speed of different ducts, the lateral diffusion and longitudinal disturbance of the greenhouse air are promoted, breaking the dead zones of airflow that are easily formed by traditional single-top ventilation ducts. At the same time, both the first and third ventilation ducts use multiple fans working together to avoid temperature and humidity imbalances or concentrated excessive wind speeds in local areas due to airflow stagnation, thus providing a more stable microenvironment for large-scale planting.

The multiple ventilation window groups, each closable and installed on the main frame group, mean that each ventilation window group can control ventilation. The ventilation volume can be controlled by controlling the number of windows opened in the ventilation window group, which not only makes the ventilation volume easy to control but also increases the adjustable range of ventilation volume, solving the problems of uneven ventilation and poor convection. The main frame group allows all ventilation window groups to be opened simultaneously, directly controlling them to reach the maximum ventilation volume requirement without adjusting each window group individually, simplifying the operation process, and achieving maximum air replacement in the shortest time, greatly increasing ventilation efficiency.

[0041] In a preferred embodiment, the first window connector 52, the second window connector 53, and the third window connector 62 are all electric push rods, whose opening and closing angles are remotely adjusted via a wireless control system. The fact that all three window connectors are remotely controlled via a wireless control system allows for remote control of the opening and closing angle of each ventilation window group. This not only increases control precision but also optimizes airflow paths and achieves gradient ventilation by controlling the opening and closing angles of different ventilation window groups.

[0042] In a preferred embodiment, the number of second window connectors 53 is twice the number of mounting units; the mounting units are arranged in a matrix structure on the main frame 51.
