Description
Technical Field
[0001] This utility model relates to the field of greenhouse environmental control technology, and in particular to a water collection device that can collect condensation inside a greenhouse. Background Technology
[0002] Dew is a natural phenomenon. When the water vapor in the atmosphere reaches saturation, it transforms from a gaseous state to a liquid state under the presence of condensation nuclei, forming condensates such as fog, frost, and dew. Dew consists of small water droplets condensing on the ground or objects on the ground. Inside greenhouses, because they are surrounded by coverings or buildings and contain vegetables, flowers, and other plants, saturated or near-saturated air condenses into dew droplets when it comes into contact with the low-temperature greenhouse building materials, coverings, or plants. While dew can help slightly wilted plants recover, excessive moisture can promote the growth of pathogens and cause diseases. For winter greenhouse production, preventing condensation and avoiding disease is an important aspect of technical management.
[0003] Meanwhile, under ample sunlight during the day, the temperature inside the greenhouse rises rapidly, and soil moisture and plant transpiration increase significantly, leading to a substantial increase in the water vapor content in the air. At night, as the temperature drops, the moisture in the air gradually reaches saturation, and water droplets are more likely to condense on cooler surfaces such as the greenhouse film, forming a noticeable condensation phenomenon. This phenomenon is particularly frequent in the cold season, not only affecting the safety of the greenhouse structure but also threatening crop health. The persistently high humidity environment easily induces various diseases, such as gray mold, downy mildew, and powdery mildew. These pathogens multiply rapidly in humid environments, easily causing large-scale disease spread. In addition, condensation dripping onto crop leaves or fruits can cause localized water accumulation, affecting photosynthetic efficiency and even causing rot, reducing crop quality and marketability. Utility Model Content
[0004] To overcome the problem of high humidity and easy condensation inside greenhouses, this utility model provides a water collection device that can collect condensation inside greenhouses.
[0005] The technical solution is as follows: A water collection device for collecting condensation inside a greenhouse includes a black water collection pipe. Multiple sets of flexible hoses for conveying condensation into the pipe are arranged sequentially from left to right at the upper end of the black water collection pipe. A guide plate is horizontally arranged at the top of each hose. A front plate is obliquely arranged on the side surface of the guide plate, and a rear plate is obliquely arranged on the other side of the guide plate at a 30° angle to the front plate. A water collection trough is formed in the cavity between the rear plate, the front plate, and the guide plate. The water collection trough is used to collect water condensed on the surface of the greenhouse roof film inside the greenhouse. The water collection troughs are connected sequentially inside the greenhouse at a 1.15° angle to the horizontal.
[0006] Furthermore, a groove is provided between every two adjacent sets of guide plates, and the groove and the hose are interlocked.
[0007] Furthermore, both the rear panel and the front panel are equipped with pins at their top ends, and the other ends of the rear panel and the front panel are provided with fastening grooves.
[0008] Furthermore, each pair of adjacent rear and front panels are connected by pins and fastening slots, and the rear, front, and deflector plates are all made of PET material.
[0009] Furthermore, a connecting groove is provided between the black water collection pipe and the flexible hose, and a cover plate is fastened to the top of the black water collection pipe.
[0010] Furthermore, multiple sets of drainage support rods are sequentially installed on the side surface of the black water collection pipe from left to right, and drainage grooves are symmetrically opened on both sides of the lower end of the drainage support rods.
[0011] Furthermore, a baffle for cleaning internal impurities is fastened to the top of the drainage support rod, and a gate valve is located inside the black water collection pipe at the rear end of the drainage support rod.
[0012] Furthermore, a handle is provided at the center of the top of the gate valve.
[0013] The beneficial effects are as follows: This utility model achieves effective collection of condensation water generated on the surface of the greenhouse roof film due to the temperature difference between day and night through the structure of the guide plate and the water collection trough, avoiding water waste. It concentrates and recycles the condensate water that would otherwise drip and waste for use in the irrigation system. It is especially suitable for arid or water-scarce areas, with good water-saving benefits, reducing the phenomenon of condensate water dripping onto crops or the ground, reducing the risk of disease transmission, keeping the ground dry, and improving the quality of the crop growth environment. The guide plate, front and rear plates and other components are made of PET material, which has good weather resistance and anti-aging ability, and is suitable for long-term outdoor and high-humidity environments. The black water collection pipe is equipped with a manual gate valve and handle, which can flexibly control the opening and closing of the water flow, making it easy to adjust the water volume or perform system maintenance.

Detailed Implementation
[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0021] Among the currently discovered feasible technologies, the following are described:
[0022] Condensation is a common natural phenomenon, essentially the process by which water vapor in the air changes from a gaseous state to a liquid state under specific conditions. When the humidity in the air approaches or reaches saturation and comes into contact with a cool surface, the water vapor condenses into tiny water droplets. This process usually requires certain condensation nuclei. In nature, this phenomenon manifests as dew on grass in the early morning, condensation on windows in cold weather, and water droplets forming on the surfaces of greenhouse structures in winter. Inside a greenhouse, the space is relatively enclosed due to the covering materials or building structure, resulting in poor air circulation. Furthermore, the large number of plants grown inside, such as vegetables, flowers, and fruit trees, absorb water through their roots and transpire through their leaves, causing the water vapor content in the greenhouse air to remain at a high level. Especially during the cold winter months, to maintain suitable temperature conditions for crop growth, ventilation time and frequency are often reduced, further exacerbating the increase in air humidity. At this time, the air inside the greenhouse easily reaches or approaches saturation, while the building materials such as the greenhouse film, steel frame, and walls, as well as the plant surfaces, become excellent condensation surfaces. When warm, humid air comes into contact with these cooler surfaces, noticeable dew droplets form. While this condensation can provide some moisture to slightly wilted plants and help them recover their physiological activity, overall, excessive condensation has a more significant negative impact on greenhouse production. First, frequent dew increases the humidity inside the greenhouse, creating an environment conducive to the reproduction and spread of pathogens, especially common diseases such as gray mold, downy mildew, and powdery mildew, which are highly susceptible to occur and spread rapidly under high humidity conditions, seriously affecting crop health and yield. Second, dew dripping onto plant leaves or fruits can directly cause localized water accumulation, affecting photosynthetic efficiency and even causing tissue rot, reducing the commercial value of agricultural products. In addition, condensation not only affects crop growth but also has adverse effects on the greenhouse structure itself. Metal frames that are constantly in a humid state are prone to corrosion, and plastic film materials may also age faster due to moisture adhesion, shortening their service life. In addition, excessive humidity may cause electrical equipment to operate unstablely, increasing safety hazards.
[0023] During the day, with ample sunlight, the temperature inside a greenhouse rises rapidly as sunlight penetrates the covering material and directly reaches the ground and crop surfaces. This accelerates soil moisture evaporation and significantly enhances plant transpiration, leading to a substantial increase in water vapor content and relative humidity. This "double humidification effect," caused by the combined effects of soil evaporation and plant transpiration, is particularly pronounced in enclosed or poorly ventilated greenhouses, often bringing the air close to or even to saturation. At night, as solar radiation weakens, the greenhouse temperature gradually decreases, especially in winter or cold seasons when the cooling is even faster. As the temperature drops, water vapor in the air cools and condenses into tiny liquid water droplets on cooler surfaces—a process commonly known as condensation. Surfaces such as greenhouse films, steel frames, plastic coverings, and crop leaves, due to their high thermal conductivity or rapid heat dissipation, become primary condensation surfaces, particularly prone to forming noticeable dew droplets. This environment of large diurnal temperature variations and high humidity is especially frequent in cold seasons, posing a potential impact not only on the internal structure of the greenhouse but also a serious threat to the healthy growth of crops. First, consistently high humidity provides ideal breeding conditions for various pathogenic microorganisms. For example, fungal diseases such as gray mold, downy mildew, and powdery mildew germinate rapidly and have strong infectivity in humid environments, easily spreading over large areas in a short time, severely affecting crop yield and quality. Second, if condensation is not removed in time, water droplets formed will often drip from the greenhouse film or other structures onto the leaves, flowers, or fruits of crops, causing localized water accumulation. This not only hinders normal photosynthesis and gas exchange in leaves but may also damage plant epidermal tissue, inducing rot and reducing the commercial value of agricultural products, especially fruit and vegetable crops such as tomatoes, cucumbers, and strawberries, as well as berry crops. In addition, greenhouse building materials such as metal frames and connectors, which are constantly exposed to moisture, will also experience accelerated oxidation and corrosion due to repeated dampness, shortening their service life; some plastic covering materials may also age and deform due to prolonged contact with condensation, affecting their heat insulation performance and light transmittance. At the same time, high humidity may also pose a risk of short circuits or unstable operation to electrical equipment and automatic control systems installed in the greenhouse, further affecting the level of intelligence in greenhouse management.
[0024] like Figures 1-5As shown, a water collection device for collecting condensation inside a greenhouse includes a black water collection pipe 1. Multiple sets of flexible hoses 2, arranged sequentially from left to right at the upper end of the black water collection pipe 1, are used to transport condensation into the pipe. A guide plate 13 is horizontally positioned at the top of each hose 2. A front plate 8 is obliquely positioned on the side surface of the guide plate 13. A rear plate 7, forming a 30° angle with the front plate 8, is obliquely positioned on the other side of the guide plate 13. A water collection trough 3 is formed in the cavity between the rear plate 7, the front plate 8, and the guide plate 13. The water collection trough 3 is used to collect water condensed on the surface of the greenhouse roof film inside the greenhouse. The water collection troughs 3 are sequentially connected inside the greenhouse, forming a 1.15° angle with the horizontal.
[0025] A groove 11 is provided between every two adjacent sets of guide plates 13. The groove 11 and the hose 2 are interlocked, which facilitates the quick installation and sealing connection between the hose 2 and the guide plate 13, and enhances the overall structural stability. The top of the rear plate 7 and the front plate 8 are provided with pins 14, and the other end of the rear plate 7 and the front plate 8 are provided with snap-fit grooves 10, which realizes the quick splicing and fixing between the front and rear plates 7, improves the assembly efficiency and connection firmness. Every two adjacent sets of rear plates 7 and front plates 8 are connected by pins 14 and snap-fit grooves 10. The rear plate 7, the front plate 8 and the guide plate 13 are all made of PET material 12. PET material 12 is lightweight and durable. With the design of pins 14 and snap-fit grooves 10, modular assembly and long-term outdoor use can be achieved.
[0026] When the water collection device is in operation, condensation caused by temperature differences on the surface of the greenhouse film falls onto the guide plate 13 area. The inclined angle allows the condensate to flow smoothly into the trough and collect sequentially along the collection channel 3. The collection channel 3 is arranged inside the greenhouse at a 1.15° angle, which helps water flow downstream by gravity and prevents water accumulation. Pipe grooves 11 are provided between the guide plates 13, tightly engaging with the lower flexible hose 2, allowing the collected condensation to be guided into the black collection pipe 1 through the hose 2. The pins 14 at the top of the front and rear plates 7 cooperate with the locking grooves 10 at their ends to achieve a stable connection between adjacent components, improving installation efficiency and enhancing the overall structural integrity. The guide plates 13, front plate 8, and rear plate 7 are all made of PET material 12, possessing good weather resistance and strength, suitable for the humid environment inside the greenhouse, and supporting modular assembly. Finally, hose 2 delivers the dew to black collection pipe 1, which then transports the collected water to the location of drainage support 4, and finally discharges it through drainage trough 16, completing the entire water collection and discharge process.
[0027] Please see Figures 3-4A connecting groove 15 is provided between the black water collection pipe 1 and the flexible hose 2. A cover plate 5 is fastened to the top of the black water collection pipe 1. The connecting groove 15 ensures a tight connection between the flexible hose 2 and the water collection pipe. The cover plate 5 can be opened for convenient daily maintenance and cleaning. Multiple sets of drainage support rods 4 are sequentially installed from left to right on the side surface of the black water collection pipe 1. Drainage grooves 16 are symmetrically opened on both sides of the lower end of the drainage support rods 4. The multi-point drainage combined with the symmetrical drainage grooves 16 design improves drainage efficiency and prevents water from concentrating and impacting the ground. A blocking frame 6 for cleaning internal impurities is fastened to the top of the drainage support rods 4. A gate valve 9 is provided inside the black water collection pipe 1 at the rear end of the drainage support rods 4. The blocking frame 6 can intercept impurities and prevent pipe blockage. The detachable design facilitates regular cleaning and maintenance. A handle 17 is provided at the center of the top of the gate valve 9. The manual gate valve 9 can flexibly control the opening and closing of the water flow for easy system adjustment.
[0028] During operation, the black water collection pipe 1 receives dew delivered from the upper hose 2 and discharges it evenly through multiple sets of drainage supports 4 installed along its side surface. Symmetrical drainage grooves 16 are located on both sides of the lower end of the drainage supports 4, ensuring stable water flow, preventing concentrated impact on the ground, and improving drainage efficiency. To prevent impurities from entering and clogging the pipe, a removable baffle 6 is installed at the top of the drainage supports 4 to intercept debris in the water and facilitate regular cleaning and maintenance. A gate valve 9 is located inside the black water collection pipe 1 at the rear end of the drainage supports 4, manually controlled by a handle 17 at the top, allowing for flexible adjustment of the water flow and facilitating system operation management and localized maintenance.
