Description

Technical Field

[0001] The utility model relates to the technical field of ventilation devices, in particular to a mobile ventilation structure for greenhouse watermelons. Background Art

[0002] Before the emergence of this mobile ventilation structure for greenhouse watermelons, the ventilation of greenhouse watermelons mainly relied on traditional fixed ventilation equipment.

[0003] Traditional fixed ventilation equipment usually installs ventilation windows at specific locations in the greenhouse and achieves ventilation through natural wind or simple mechanical ventilation devices. However, this method has many shortcomings.

[0004] On the one hand, the position of the fixed ventilation windows cannot be flexibly adjusted, which leads to uneven ventilation. Some areas in the greenhouse may be well ventilated, while other areas are not well ventilated, affecting the overall growth environment of the watermelon.

[0005] On the other hand, traditional ventilation equipment struggles to precisely control ventilation volume and direction. It lacks the flexibility to adjust to varying weather conditions, the watermelon's growth stage, and other factors. This can lead to insufficient ventilation in hot weather, effectively failing to lower the greenhouse temperature. In cold weather, the inability to adjust ventilation in time can lead to excessively low temperatures inside the greenhouse.

[0006] Furthermore, traditional ventilation systems are relatively inconvenient to operate, often requiring tedious manual opening and closing operations, and are difficult to adjust for various ventilation angles. Furthermore, traditional ventilation systems generally have limited functionality, failing to provide all-around, multi-angle ventilation, nor can they be quickly moved to meet ventilation requirements at different locations.
