[0002] In order to ensure the temperature and ventilation inside the greenhouse, traditional greenhouses usually have ventilation openings at both ends after they are built. However, this ventilation method is inefficient and cannot ventilate the greenhouse when there is no wind. In addition, the ventilation openings are easily deformed by the pressure of snow accumulation. Therefore, the ventilation method of traditional greenhouses has the problems of low ventilation efficiency and insufficient environmental adaptability. Utility Model Content

A mechanical ventilation device is provided inside the greenhouse body. The mechanical ventilation device includes a horizontal ventilation duct and a vertical ventilation duct. The horizontal ventilation duct is installed at the upper end inside the greenhouse body and is connected to a fan that communicates with the outside of the greenhouse body. The horizontal ventilation duct has multiple ventilation holes. The vertical ventilation duct is vertically installed inside the greenhouse body. The upper end of the vertical ventilation duct has ventilation holes, and the lower end of the vertical ventilation duct extends out of the greenhouse body and is connected to the fan that communicates with the outside of the greenhouse body. A natural ventilation device is also provided at the top of the greenhouse body.

[0005] Optionally, multiple transverse air guide ducts are provided, each of which is individually connected to a fan. Some transverse air guide ducts have air guide holes along their entire length, while others have air guide holes along only a portion of their length.

[0006] Optionally, the top of the vertical air guide duct is provided with an air guide cover.

[0007] Optionally, the natural ventilation device includes a skylight and a side window. The skylight is located on the top of the greenhouse body, and the side window is located on the side wall of the greenhouse body. The side window is equipped with an adjustable-angle guide plate.

[0008] Optionally, the skylight is equipped with a push-rod type roof window, the size of which is larger than the size of the skylight, and the side window is equipped with a roll-up window, the size of which is larger than the size of the side window.

At the same time, air guiding holes are set at different positions of the air guiding pipe to provide targeted ventilation for different areas of the greenhouse, which is highly efficient.

[0012] 2. This utility model links the side wall and the roof ventilation opening, allowing hot air to be discharged through the top window and cold air to enter through the side window, forming vertical convection. At the same time, the adjustable guide plate optimizes the airflow path to avoid direct airflow onto crops. In conjunction with the internal air guiding device, it enhances the air guiding efficiency. Attached Figure Description

[0018] The following combination Figure 1-4 The present invention will be described in further detail below.

[0019] This utility model discloses a wind guide device for greenhouses, referring to... Figure 1 and Figure 2 The system includes a greenhouse body 1, which contains a mechanical ventilation system. The mechanical ventilation system includes a horizontal ventilation duct 2 and a vertical ventilation duct 3. The horizontal ventilation duct 2 is installed at the upper part of the greenhouse body 1 and is connected to a fan 4 that communicates with the outside of the greenhouse body 1. The horizontal ventilation duct 2 has multiple air guide holes 5. The vertical ventilation duct 3 is installed vertically inside the greenhouse body 1. The upper end of the vertical ventilation duct 3 has air guide holes 5, and the lower end of the vertical ventilation duct 3 extends out of the greenhouse body 1 and is connected to the fan 4 that communicates with the outside of the greenhouse body 1. The top of the greenhouse body 1 is also equipped with a natural ventilation system. There are multiple horizontal ventilation ducts 2, each of which is individually connected to a fan 4. Some horizontal ventilation ducts 2 have air guide holes 5 along their entire length, while others have air guide holes 5 only along a portion of their length. The top of the vertical ventilation duct 3 is equipped with a ventilation hood 11.

[0020] Specifically, the horizontal air guide duct 2 is connected to the side wall of the greenhouse body 1 at both ends. Both ends can be connected to the fan 4, or only one end can be connected. The air guide holes 5 on it can be set in various ways, such as full length setting, half-section setting, and interval setting. The specific method is designed according to the needs of different areas in the greenhouse. The lower end of the vertical air guide duct 3 can extend from the greenhouse body 1 through a bend, or it can extend to the bottom of the greenhouse body 1 below the ground and then extend out of the ground through a bend, which can avoid occupying the usable area inside the greenhouse body 1.

[0021] In a further implementation, refer to Figure 3 and Figure 4 The natural ventilation system includes a skylight 6 and a side window 7. The skylight 6 is located on the top of the main body 1 of the greenhouse, and the side window 7 is located on the side wall of the main body 1 of the greenhouse. The side window 7 is equipped with an adjustable angle guide plate 8. The skylight 6 is equipped with a push-rod type top window 9, which is larger than the skylight 6. The side window 7 is equipped with a roll-up window 10, which is larger than the side window 7. The skylight 6 and the side window 7 are equipped with insect-proof nets and dust-proof filter cloths.

[0022] Specifically, side windows 7 are provided on both sides of the main body 1 of the greenhouse, and skylights 6 are provided on both sides of the gutter at the top of the main body 1 of the greenhouse. These can receive wind blowing from different directions. The push-rod type top window 9 opens outward, and the roll-up window 10 rolls up. Both of these are larger than the side windows 7 or skylights 6. When closed, they can form good support and resist strong winds and snow, preventing the skylights 6 or side windows 7 from deforming. Multiple guide plates 8 inside the side window 7 are rotatably connected to the side wall of the side window 7 by connecting rods. Each connecting rod is connected by a push rod 12, so that the guide plates 8 can be linked and change their angles simultaneously.

[0023] The side window 7 of this utility model is linked with the skylight 6 ventilation opening. Hot air is discharged through the top window and cold air enters through the side window, forming vertical convection. At the same time, the airflow path is optimized by the adjustable guide plate to avoid direct airflow onto the crops.

[0024] In a further embodiment, a temperature and humidity sensor is installed inside the greenhouse body 1. The temperature and humidity sensor is linked to the fan 4. The intensity and opening and closing of the fan 4 are controlled by the data collected by the temperature and humidity sensor, thereby dynamically adjusting the airflow intensity, which is beneficial to crop growth.

[0025] In this invention, internal mechanical air guiding devices and natural air guiding devices can be selectively installed, but mechanical air guiding devices are the main type. When the greenhouse size is small, only natural air guiding devices or mechanical air guiding devices can be installed. When the greenhouse size is large, only mechanical air guiding devices can be installed. When the greenhouse size is too large, both mechanical air guiding devices and natural air guiding devices can be installed. At the same time, air guiding devices for both mechanical and natural air guiding devices can be added to improve ventilation efficiency.

[0026] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
