Abstract
Description
Technical Field
[0001] This utility model relates to the field of greenhouses, specifically to a glass greenhouse for collecting dew. Background Technology
[0002] Greenhouses, also known as heated rooms, are structures that allow light to pass through while maintaining or heating the greenhouse. They are primarily used for cultivating plants or crops. Especially during seasons unsuitable for plant growth, they provide a growing period and increase yields, and are commonly used for cultivating or raising seedlings of warm-season vegetables, flowers, and trees. To enhance the functionality and efficiency of greenhouses, current technology often installs translucent glass or photovoltaic panels on the roof. However, this can lead to water vapor condensing on the back of the glass or panels and dripping down, potentially compromising safety within the greenhouse.
[0003] Utility model patent CN221956838U discloses a photovoltaic dew collection device, including a support frame, a photovoltaic panel, and a mist-catching component. The support frame includes a top support base that slopes upwards from front to back and a front column row and a rear column row located at the bottom of the top support base. The photovoltaic panel is supported on the top support base. The mist-catching component includes a rear mist-catching net and a rear collection trough. The rear collection trough is inclined along its extension direction, and its lower end is connected to a rear guide channel. The mist-catching component of this photovoltaic dew collection device can automatically capture and collect mist droplets in the air and collect them into liquid water, thereby meeting the water needs of outdoor maintenance personnel and solving their difficulties in accessing domestic water. However, the disclosed structure of this device is suitable for outdoor collection and is not suitable for dew collection inside greenhouses where significant structural modifications are required. Utility Model Content
[0004] In order to collect the dew condensed inside the greenhouse without changing the existing greenhouse structure, the technical solution adopted by this utility model is: a dew-collecting glass greenhouse, including several sets of supporting columns, with supporting beams arranged between each set of supporting columns, and longitudinal beams arranged on the top of the supporting beams; fixed seats are arranged on the top of the supporting columns and the top of the longitudinal beams, and light-transmitting components are covered between two adjacent fixed seats;
[0005] A condensation collection assembly is provided between the fixed base and the longitudinal beam. The condensation collection assembly includes a fixed plate attached to the top of the longitudinal beam and bending grooves horizontally connected to both ends of the fixed plate. The bending grooves are located directly below the ends of the light-transmitting assembly.
[0006] Based on the above, in order to improve the sealing performance of the condensation collection component and prevent water leakage, the fixing plate is integrally formed with the pair of bending grooves.
[0007] Based on the above, in order to improve the ability to collect dew, the bottom of the bending groove is set lower than the top surface of the longitudinal beam.
[0008] Based on the above, in order to facilitate the recycling of the collected dew, the bending groove extends along the length of the longitudinal beam, and the bending groove is inclined with one end higher than the other.
[0009] Based on the above, in order to increase the range and area of dew collection, the projected width of the dew collection component in the horizontal direction is greater than the projected width of the fixing base in the horizontal direction.
[0010] Based on the above, in order to facilitate the collection of rainwater from the top of the greenhouse, the top of the fixing seat is provided with an opening to form a U-shaped water collection trough.
[0011] Based on the above, in order to drain water in a timely manner, the light-transmitting component includes several light-transmitting glass panels, and one end of the several light-transmitting glass panels is spliced together to form a roof ridge.
[0012] Based on the above, in order to increase the functionality of the greenhouse, the light-transmitting component also includes several photovoltaic panels installed on the light-facing side.
[0013] Based on the above, the supporting beam is a truss structure.
[0014] This utility model has substantial features and advancements compared to existing technologies. Specifically, it provides a dew-collecting glass greenhouse by designing the greenhouse structure as a combination of supporting columns and crossbeams. Several longitudinal beams are installed on the crossbeams, and water collection troughs are mounted on these longitudinal beams. A dew-collecting component is positioned between the water collection troughs and the longitudinal beams. This design allows for stable support of the dew-collecting component using the longitudinal beams, ensuring that the two bending grooves of the dew-collecting component are directly below the light-transmitting components. Thus, it enables the timely collection of condensed dew within the greenhouse without altering the existing greenhouse structure.
[0015] Furthermore, by designing the dew collection component as an integrally molded fixed plate with a pair of bending grooves, it is possible to ensure that the dew collection component not only has a certain capacity to store dew, but also has the advantages of convenient installation and wide collection range.

To improve the dew-collecting capacity, the bottom of the bending grooves 9 is lower than the top surface of the longitudinal beam 5. To facilitate the recovery of the collected dew, the bending grooves 9 extend along the length of the longitudinal beam 5, and are inclined with one end higher than the other, thereby allowing the collected dew in the bending grooves 9 to flow from one end to the other.
[0026] Example 3
[0027] This embodiment provides a dew-collecting glass greenhouse. The main difference from Embodiment 1 is that, in order to increase the range and area of dew collection, the horizontal projection width of the dew-collecting component is greater than the horizontal projection width of the fixing base, thereby enabling timely collection of dripping dew.
