Description

Technical Field

[0001] This utility model relates to the field of greenhouse roof waterproofing and drainage technology, specifically to a rainproof and leakproof structure for glass greenhouses. Background Technology

[0002] Glass greenhouses, as an important form of modern facility agriculture, are widely used due to their advantages such as high light transmittance, strong environmental control capabilities, and long service life. Their roofs are typically constructed by multiple glass panels overlapping a gable beam frame. However, the joints between the glass panels and between the glass panels and the drainage gutters are the weakest points in the entire roof system. Under long-term exposure to wind and rain, especially strong storms, rainwater can easily seep into the greenhouse through these joints.

[0003] To address the aforementioned leakage issues, existing glass greenhouse roof structures typically employ a combination of sealant and mechanical fastening. Specifically, a common practice is to directly fix the ends of the A-frame beams to the gutters, with the lower ends of the glass panels between adjacent A-frame beams overlapping the edge of the gutters. For sealing, construction workers fill the gaps between the glass panels and the gutters with a large amount of silicone weather-resistant sealant to create a tight, waterproof layer.

[0004] However, the aforementioned rainproof structure relying on extensive sealant application has significant and insurmountable drawbacks. First, the sealant, when exposed to ultraviolet radiation, rainwater, and drastic temperature and humidity changes over a long period, inevitably ages, hardens, cracks, and shrinks, leading to a rapid decline in its sealing performance. It typically requires reapplying after several years, resulting in high maintenance costs and short-lived effectiveness. Second, this structure lacks an effective secondary drainage and water-conducting mechanism. Once the sealant fails, or rainwater is forced into the joints under strong wind pressure, the infiltrated water accumulates directly in structural grooves such as the connection between the gutters and the gable beams, unable to drain promptly. This accumulated water not only accelerates the corrosion of metal components but also, driven by capillary action or wind pressure, easily overcomes the obstruction of the gutter edges, ultimately seeping into the greenhouse interior. In other words, the existing technology is a passive, single-minded anti-blocking strategy, lacking the ability to actively guide and drain infiltrated water, resulting in poor leak-proof reliability.

[0005] Therefore, the above problems urgently need to be solved. Utility Model Content

[0006] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a rainproof and leakproof structure for glass greenhouses. By integrating a water collection chamber and a water guide hole into the gutter and setting multiple sealing and pressing components, a collaborative leakproof system is constructed that can actively guide the rainwater that has seeped in and block it in multiple ways, thereby significantly improving the rainproof reliability and durability of glass greenhouses in long-term wind and rain environments.

[0007] Technical Solution: This utility model provides a rainproof and leakproof structure for a glass greenhouse, including a gutter, which is mounted on a gutter bracket and has a long, hollow structure. The lower inner side has a water collection chamber, and the upper outer side has a pair of symmetrically distributed slots on both sides above the water collection chamber. The water collection chamber is used to drain collected rainwater outside the glass greenhouse. A pair of water guide holes are respectively located at the bottom of the pair of slots to guide rainwater seeping into the water collection chamber. Several A-frame beams are spaced apart along the extension direction of the gutter, with the end of each A-frame beam obliquely embedded in a corresponding slot. Several glass panels are embedded between the two A-frame beams, with their lower ends overlapping a support portion at the upper end of the gutter. A first sealing component is located between the lower end of the glass panel and the support portion to prevent rainwater on the glass panel from seeping into the glass greenhouse. The gutter, a long, hollow structure, has a collection chamber on its lower side that collects rainwater from the top of the glass greenhouse. This water is then directed out of the greenhouse, preventing water accumulation on the roof. A pair of slots on the upper exterior of the gutter are used to embed the ends of the A-frame beams, while a pair of drainage holes at the bottom of these slots guide any rainwater seeping into the collection chamber, preventing stagnation. Several A-frame beams are spaced apart along the gutter's extension direction, their ends angled and embedded in the slots, providing stable support for the glass panels. The glass panels are embedded between the two A-frame beams, their lower ends overlapping the support portion of the gutter, achieving precise positioning and fixation of the glass panels and ensuring the overall structural stability. A first sealing component is located between the lower end of the glass panel and the support portion, tightly sealing the gap between them to prevent rainwater from seeping into the glass greenhouse, forming a leak-proof barrier.

[0008] Furthermore, in this application, a rainproof and leakproof structure for a glass greenhouse includes a support portion and a stop portion. The support portion extends along the inclined direction of the herringbone beam to accommodate the edge of the glass panel, and the stop portion is formed by bending upward from the end of the support portion. The first sealing component includes a glass gasket strip, which extends axially along the gutter and engages with the stop portion, and abuts against the lower cross-section of the glass panel.

[0009] Furthermore, in a rainproof and leakproof structure for a glass greenhouse, the first sealing component further includes a gutter PVC strip, which extends along the gutter axis. The upper end of the gutter is also provided with a pair of second slots. The gutter PVC strip has an F-shaped cross-section and is engaged in the second slots. The long side of the gutter PVC strip is pressed against the upper surface of the glass panel. The support extends along the inclined direction of the herringbone beam, precisely adapting to the tilt angle of the glass panel and providing a close-fitting support surface for the glass edge, preventing instability caused by angular misalignment. The stop bends upward from the end of the support, which on the one hand, can intercept the glass gasket, preventing it from shifting axially or radially along the gutter; on the other hand, it can limit the lateral movement of the glass panel, preventing the glass edge from detaching from the support. The glass gasket extends axially along the gutter, forming a continuous sealing strip that covers the entire contact gap between the lower end of the glass panel and the support, preventing localized leakage. The glass gasket is locked in place with the stop and can maintain its sealed position independently without the need for additional adhesives or fasteners; at the same time, it closely contacts the cross-section of the lower end of the glass panel, filling the tiny gaps between them and preventing rainwater from seeping in.

[0010] Furthermore, in a rainproof and leak-proof structure for a glass greenhouse, the lower side of the free end of the long side of the PVC gutter strip is provided with a water-resistant strip extending towards the center line of the gutter. The water-resistant strip is pressed against the upper surface of the glass panel, forming a multi-layered water-blocking structure together with the long side of the PVC gutter strip. The long side of the PVC strip itself can block some rainwater, and together with the water-resistant strip below, it forms a two-layered water-blocking structure. Even if a small amount of rainwater passes through the water-resistant strip, it still needs to overcome the obstruction of the long side of the PVC strip to reach the sealing gap, thus constructing multiple water-blocking barriers.

[0011] Furthermore, in one rainproof and leakproof structure for a glass greenhouse, the A-frame beam is provided with a pair of symmetrically arranged third slots. The glass panel is respectively embedded in the third slots of two adjacent A-frame beams along both sides of the gutter axis. The pair of symmetrically arranged third slots on the A-frame beam can precisely match the two sides of the glass panel along the gutter axis, ensuring that the glass can be quickly aligned during installation, avoiding lateral offset, and ensuring flatness when multiple glass panels are spliced.

[0012] Furthermore, in one rainproof and leakproof structure for a glass greenhouse, the third slot is fitted with a sealing strip that abuts against the side surface of the glass panel. The leakproof structure at the gutter focuses on the lower end of the glass, the waterproof strip focuses on the upper surface of the glass, and the sealing strip targets the gaps on the side of the glass. Together, these three elements completely block the key paths through which rainwater may seep in.

[0013] Furthermore, in one rainproof and leakproof structure for a glass greenhouse, the sealing strip has an O-shaped cross-section and is made of EPDM rubber.

[0014] Furthermore, in a rainproof and leakproof structure for a glass greenhouse, the end of the support portion is provided with an inwardly bent hook, and the end of the A-frame beam is provided with a fourth locking groove, the hook engaging with the fourth locking groove. The hook, after bending inward, embeds into the fourth locking groove, forming a mechanical locking structure for limiting its position.

[0015] As can be seen from the above technical solution, this utility model has the following beneficial effects: 1. The rainproof and leak-proof structure for glass greenhouses described in this utility model constructs an active drainage system by integrating a water collection chamber and water guide holes into the gutters. This system can promptly guide rainwater that seeps into the slots into the water collection chamber and discharge it outdoors, preventing rainwater from stagnating in the structural slots. This fundamentally solves the problems of water accumulation accelerating metal corrosion and seeping into the greenhouse through capillary action or wind pressure in existing technologies, significantly improving the reliability of leak prevention.

[0016] 2. The rainproof and leakproof structure for glass greenhouses described in this utility model features multiple synergistic sealing components, forming a three-dimensional leak-proof barrier. Glass gaskets seal the gap at the bottom of the glass, PVC gutter strips and waterproof strips prevent rainwater from entering the upper surface of the glass, and O-ring sealing strips on the herringbone beams seal the side gaps of the glass. These three components work together to replace the traditional reliance on a single sealant, effectively resisting the degradation of sealing performance caused by ultraviolet radiation and changes in temperature and humidity, extending the durability of the structure, and reducing later maintenance costs.

A pair of second slots 14 are also provided at the upper end of the gutter 1. The gutter PVC pressure strip 52 extends axially along the gutter 1, and its cross-section is F-shaped, and it is engaged in the second slots 14. The long side of the gutter PVC pressure strip 52 is pressed against the upper surface of the glass panel 4, and a water-blocking strip 521 extending towards the centerline of the gutter 1 is provided on the lower side of its free end. The water-blocking strip 521 is pressed against the upper surface of the glass panel 4, and together with the long side of the gutter PVC pressure strip 52, they form a multi-layer water-blocking structure.

[0025] In this embodiment, the regular arrangement of the water guide holes 6, the active drainage function of the water collection chamber 11, and the multiple sealing system composed of the glass gasket 51, the gutter PVC pressure strip 52, the water-proof strip 521 and the sealing strip 311 effectively realize the active drainage and coordinated leak prevention of rainwater, thereby improving the rainproof reliability and durability of the glass greenhouse.
