Description

Technical Field

[0001] This utility model relates to the field of greenhouse technology, specifically to a multi-window linkage ventilation structure for glass greenhouses. 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 / (m²・K), which is lower than the heat transfer coefficient of single-glazed glass of 5.0 W / (m²・K). In winter, it can reduce heat loss and lower 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 are often designed with single or double opening and closing. The ventilation volume is controlled by adjusting the opening angle of each window. Not only is the adjustable range small, but the ventilation volume is also difficult to control, resulting in uneven ventilation and poor convection. Moreover, the single-window adjustment method of traditional windows can only create 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. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this utility model designs a multi-window linkage ventilation structure for glass greenhouses, comprising: a greenhouse frame, a top multi-window linkage ventilation structure, and a side multi-window linkage ventilation structure; wherein, the top multi-window linkage ventilation structure is installed on the top of the greenhouse frame for top ventilation of the glass greenhouse; and the side multi-window linkage ventilation structure is installed on the side of the greenhouse frame for side ventilation of the glass greenhouse.

[0007] 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 work together for top ventilation of the glass greenhouse; wherein, the first multi-window linkage structure is installed on the top of the greenhouse frame; the first fan is installed on the greenhouse frame and is located below the first multi-window linkage structure.

[0009] Preferably, the first multi-window linkage structure and the second multi-window linkage structure have the same structure, both including: a main frame group and a ventilation window group; the main frame group is closable and installed on the greenhouse frame; there are multiple ventilation window groups, and multiple installation units are provided on the main frame group, the number of ventilation window groups is equal to the number of installation units; the multiple ventilation window groups are closable and installed on the multiple installation units respectively.

[0010] 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 greenhouse frame; 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.

[0011] Preferably, the ventilation window assembly includes: a ventilation window and a third window connector; the number of third window connectors is two, the two third window connectors are respectively installed at both ends of the ventilation window and connected to the second window connector, and cooperate with the second window connector to install the ventilation window in an openable and closable manner on the mounting unit.

[0012] Preferably, the first window connector, the second window connector, and the third window connector all use electric push rods, and the opening and closing angles of the electric push rods are remotely adjusted through a wireless control system.

[0014] Preferably, the number of installation units is not less than 2.

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

[0017] 2. 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.

[0018] 3. 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.

[0019] 4. 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.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1 like Figures 1-6 As shown, this utility model provides a multi-window linkage ventilation structure for a glass greenhouse, including: a greenhouse frame 1, a top multi-window linkage ventilation structure 2, and a side multi-window linkage ventilation structure 3; wherein, the top multi-window linkage ventilation structure 2 is installed on the top of the greenhouse frame 1 for top ventilation of the glass greenhouse; the side multi-window linkage ventilation structure 3 is installed on the side of the greenhouse frame 1 for side ventilation of the glass greenhouse. 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 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 easier to control but also increases the adjustable range of ventilation volume, solving the problems of uneven ventilation volume and poor convection effect. 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.

[0034] In a preferred embodiment, the first window connector 42, the second window connector 43, and the third window connector 52 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 the airflow path and achieves gradient ventilation by controlling the opening and closing angles of different ventilation window groups.

[0036] In a preferred embodiment, the number of installation units is not less than 2.
