Embodiment 2 (not shown in the figure)

The difference from the first embodiment is that on the basis of the first embodiment, the greenhouse further includes: a temperature control module, including a temperature measurement module and a control module, the temperature measurement module is used to measure the temperature inside and outside the greenhouse, and control The module is electrically connected to the film winding motor 202 and the temperature measurement module, and can start the film winding motor 202 when the difference between the internal temperature and the external temperature of the greenhouse is within a preset range.

The greenhouse also includes a temperature control module. The temperature control module includes a temperature measurement module for measuring the temperature inside and outside the greenhouse and a control module that is electrically connected to the film motor 202 and the temperature measurement module. When the difference of the external temperature is within the preset range, the film winding motor 202 is started to realize the automatic operation of the film winding device and the automatic operation of the liquid collection assembly, which improves the automation and intelligence level of the product, and makes the liquid collection tank 302 collects dew more timely, which greatly improves the user experience.

The specific structure and working principle of the greenhouse provided in this application will be described in detail below with reference to a specific embodiment.

As shown in Figures 1 to 4, the greenhouse provided by this application mainly includes the following parts: side purlin 102, column 101, gutter 105, arch 104, climbing rod 203, arch 104 lower chord 103, rotating shaft (ie Fixed rotating shaft 204), rolling rotating shaft (that is, rolling bearing 303), film winding motor 202, suspension (that is, suspension belt 301), liquid collection tank 302, film winding rod 201.

Working logic: one end of the climbing rod 203 is connected to the rotating shaft (ie, the fixed rotating shaft 204), and one end is connected to the film winding motor 202. When the film winding motor 202 is working, the film winding rod 201 rotates and rises along the greenhouse skeleton to roll up the film on the greenhouse , So as to achieve the function of rolling film. A pair of rolling shafts are installed on the film rolling rod 201, the upper end of the suspension (ie suspension belt 301) is around the rolling shaft (ie rolling bearing 303), and the lower end is connected to the liquid collection tank 302, under the rotation of the rolling shaft (ie rolling bearing 303) and the action of gravity , The liquid collection tank 302 always maintains a vertical direction.

When the temperature difference between day and night is small and the dew on the film does not form drips but adheres to the film, the film winding motor 202 starts, and the film starts to wrap around the film winding rod 201 while the film winding rod 201 rises. The number of windings of the film on the film rod 201 increases, and the dew around the film rod 201 will gradually increase, eventually forming dew. The dew will drip into the bottom due to the rotation of the film rod 201 and under its own gravity. In the sump 302, the sump 302 is parallel to the gutter 105, and the end of the sump 302 is connected to the outdoors with a slope, and the collected dew is discharged to the outdoors.

In summary, the liquid collection device provided in the present application effectively prevents the dew on the film from directly dropping into the greenhouse after it hits the frame, causing burns and other adverse effects on the plants, and reduces the humidity caused by more dew in the greenhouse. Therefore, diseases and insect pests are prone to occur. At the same time, since the film rod can rise along the greenhouse frame, when the film rod rises to the top of the greenhouse and rolls up the film on the top of the greenhouse, the dew attached to the film on the top of the greenhouse will follow The film is rolled up and drips into the liquid collecting tank below the film roll rod. Therefore, the liquid collecting device can also be used to collect the dew on the film on the top of the greenhouse, which solves the problem that the prior art cannot collect the dew on the film on the top of the greenhouse. The problem is that because the liquid collecting assembly is connected with the film rod, it does not occupy the planting space inside the greenhouse, which helps to improve the space utilization rate of the greenhouse cultivation, and the liquid collecting device has a simple structure and convenient assembly, which effectively reduces the cost of greenhouse cultivation facilities.
