[0039] It should be noted that the inner bottom of the fixed box 201 is fixedly connected with a support bracket 1 204 and a support bracket 2 207. These two groups of support brackets cooperate with each other, jointly bear the weight of the system, and provide support and guidance for subsequent motion components. The top of the support bracket 1 204 is fixedly connected with a propulsion rod 208, which is used to push the lifting block 205 up and down to achieve the adjustment function of the air circulation system. The top of the propulsion rod 208 is slidably connected to the inside of the lifting block 205, and a sliding track 209 is provided in the lifting block 205. This design ensures that the lifting block 205 can be smoothly lifted and lowered in a fixed track, thereby making the airflow adjustment more accurate. The top of the lifting block 205 is fixedly connected with a control end 202. One side of the control end 202 is fixedly connected with a main support plate 203, which provides a strong support for the entire circulation mechanism 2 and ensures that the equipment will not be deformed or damaged in a high temperature environment.

With the support of the bottom support plate 8, the push arm 6 can maintain a stable motion trajectory and reduce mechanical failures that may be caused by imbalance or instability. At the same time, the bottom support plate 8 also helps to disperse the load generated when the drive system is working, prolong the service life of the device, and the movable arm 6 is installed inside the driver 11. The driver 11 transmits power to the sunshade panel 10 through the push arm 6, driving the lifting and adjustment of the sunshade panel 10, ensuring that the sunshade effect in the greenhouse can be adjusted in real time according to changes in external light intensity.

[0049] It should be noted that the bottom support plate 8, as an important supporting base, bears the supporting force of the circulation mechanism 2 during the rotation process. By tightly connecting the bottom support plate 8 with the circulation mechanism 2, the bottom support plate not only provides the necessary stability, but also effectively disperses the pressure generated by the rotation of the circulation mechanism 2.
