Description

Technical Field

[0001] This utility model is a structure for preventing rainwater leakage in a light-transmitting cover. Background Technology

[0002] In modern industrial buildings, skylights, as an important structure for providing natural lighting, are widely used in the roof systems of factories, warehouses, and large workshops. However, in actual engineering use, skylight structures are prone to structural problems such as rainwater leakage due to long-term exposure to wind, rain, and alternating hot and cold environments.

[0003] Taking a certain phase of a thermal power plant construction project as an example, after a period of operation, rainwater leakage occurred between the skylights and the frame due to the aging of the sealant. This caused rainwater to seep into the plant and affect the operational safety of electrical equipment. On-site inspection revealed that the skylight structure used in this project generally had the following defects: sealing relies on adhesive materials: the gaps between the existing skylights and the frame are mostly filled with a single sealant. However, the sealant is prone to aging, peeling, or cracking under long-term ultraviolet radiation, high and low temperature changes, and structural micro-movements, leading to sealing failure. Utility Model Content:

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a structure for preventing rainwater leakage in a light-transmitting cover.

[0005] A structure for preventing rainwater leakage in a skylight includes a square tube and a water collection trough. The square tube has an inlet and an outlet on its opposite side walls, with the outlet located at the bottom of the side wall. The water collection trough is fixedly installed on the side wall where the inlet of the square tube is located and at its height.

[0006] Furthermore, the water collection trough has an L-shaped bending structure, and its side and bottom edges form a U-shaped groove with the side wall of the square pipe.

[0007] Furthermore, the bottom edge is a sloping structure, which is set from high to low from its side to the side wall of the square tube.

[0008] Furthermore, the bottom of the square tube has a sloping structure, which is set from high to low from the outlet side to the drain side.

[0009] Furthermore, a baffle plate is installed at the drain outlet.

[0010] Furthermore, the water collection trough, square pipe, and water baffle are fixedly connected by welding.

[0011] Beneficial effects: Compared with the prior art, the present invention has the following advantages:

[0012] 1. High drainage efficiency and strong seepage prevention capability

[0013] This structure employs a square tube combined with a water collection trough to form a closed drainage channel, which quickly guides rainwater to the drain outlet, preventing water accumulation around the skylight. Simultaneously, the sloping bottom and the bottom edge of the water collection trough utilize gravity to increase water flow velocity, ensuring smooth drainage and significantly enhancing the system's drainage efficiency. Through multi-layered flow guidance design, it effectively prevents rainwater from seeping into the skylight's interior, improving overall sealing performance.

[0014] 2. Sturdy structure and reliable sealing

[0015] The structure employs welding to firmly connect the water collection trough, square pipe, and water baffle, which are then welded together with the angle steel base to form an integrated drainage frame. This connection method improves the mechanical strength between components and avoids the loosening and cracking problems that may occur with bolts or adhesives. Furthermore, the capping plate is fixed with screws, and weather-resistant sealant is used to seal the gaps, creating a double-layer waterproof barrier to ensure structural stability and reliable sealing during long-term use.

[0016] 3. Easy to install and highly adaptable

[0017] This structure was designed with construction convenience in mind. Modular components such as square tubes, water collection troughs, and capping plates can all be prefabricated and quickly installed on-site. The process involves first installing the angle steel base, then welding the frame, and finally adding the capping plate and sealant – a clear and easy-to-operate procedure. Furthermore, this structure is suitable for the perimeter of skylights of different shapes and sizes, and the shape and installation method of the water collection trough can be flexibly adjusted to meet various architectural design requirements.

[0018] 4. Safe to use and easy to maintain

[0019] Through simulated environmental testing, the structure has been verified to maintain excellent drainage under severe weather conditions such as heavy rainfall, reducing the probability of leakage to zero and ensuring a dry and safe environment within the light-transmitting area. Its high degree of structural integration reduces the frequency of maintenance, and daily inspections and cleaning are easy to implement, contributing to extended service life and lower maintenance costs.

[0022] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0023] A structure for preventing rainwater leakage in a skylight includes a square tube 1 and a water collection trough 4. The square tube 1 has an inlet 2 and a drain 3 on its opposite side walls. The drain 3 is located at the bottom of the side wall. The water collection trough 4 is fixedly installed on the side wall where the inlet 2 of the square tube 1 is located and at its height.

[0024] The basic idea behind this rainwater leakage prevention structure is to install a drainage system with a water collection trough 4 in the frame area of ​​the skylight. A square pipe 1 forms a closed flow channel, with inlets 2 and outlets 3 on its two side walls. The water collection trough 4 is fixedly installed on the outer wall of the inlet 2 side to collect rainwater and guide it into the square pipe 1. When rainwater falls into the water collection trough 4, it flows into the square pipe 1 through the inlet 2 and then exits through the outlet 3 at the bottom, effectively preventing rainwater from seeping into the inner structure of the skylight.

[0025] This embodiment, by setting up an independent water collection trough 4 and a drainage structure that cooperates with the square pipe 1, can achieve timely collection and drainage of rainwater on the outside of the skylight, preventing water from seeping into the interior through structural gaps and improving the overall sealing and seepage prevention performance of the skylight. In addition, the structure is highly modular, easy to process and install, and helps to improve construction efficiency and system maintainability.

[0026] In one possible implementation, the water collection tank 4 is an L-shaped bent structure, with its side and bottom edges forming a U-shaped groove with the side wall of the square tube 1.

[0027] The structure utilizes an L-shaped bend in the water collection trough 4, with one side tightly fitted to the outer perimeter of the skylight, and the bottom side extending inward and attaching to the side wall of the square tube 1, forming a U-shaped enclosure. This U-shaped trough not only provides a stable connection but also collects and guides rainwater, effectively gathering rainwater falling into the edge area and directing it to the inlet 2 of the square tube 1. This geometric configuration enhances rainwater diversion efficiency and ensures a stable installation.

[0028] The L-shaped bending structure allows for one-piece molding of structural components, simplifying manufacturing and installation processes and improving processing efficiency. The U-shaped channel formed by the L-shaped bending and the square tube 1 effectively intercepts and guides rainwater into the piping system, significantly improving drainage performance and reducing the risk of leakage. This structure enhances the system's mechanical strength and sealing performance, making it suitable for long-term outdoor use.

[0029] In one possible implementation, the bottom edge is a sloping structure (not shown in the figure), which is set from high to low from its side edge to the side wall of the square tube 1.

[0030] The bottom edge of the water collection trough 4 is designed as a sloped structure with a certain gradient, and its height gradually decreases from the outer edge of the water collection trough 4 inward to the side wall of the square pipe 1. This slope helps to guide rainwater toward the inlet 2 of the square pipe 1 and improves the flow efficiency by utilizing the gravity natural drainage mechanism, thus avoiding water accumulation or backflow in the water collection trough 4.

[0031] By incorporating a sloping structure, the flow rate of rainwater is accelerated, reducing the residence time of rainwater in the collection trough 4, thereby significantly reducing the risks of structural dampness, corrosion, and freezing. Furthermore, the sloping design also helps keep the pipes clean, reducing maintenance frequency and improving the overall reliability and service life of the drainage system.

[0032] In one possible implementation, the bottom of the square tube 1 is a sloping structure (not shown in the figure), which is set from high to low from the outlet side to the drain outlet 3 side.

[0033] This structure creates a sloping drainage channel by setting a longitudinal inclination angle at the bottom of the square pipe 1, causing it to gradually descend from the outlet end towards the drain outlet 3. In this way, rainwater entering the square pipe 1 can flow along the sloping bottom direction under the action of gravity and be concentrated at the drain outlet 3 for smooth discharge from the system.

[0034] The sloping bottom design significantly improves drainage efficiency, preventing water stagnation or accumulation inside the square pipe 1, thus reducing the risk of blockage and corrosion. This structure achieves continuous drainage without the need for a power unit, making it a highly efficient and energy-saving rainwater drainage solution, particularly suitable for continuous drainage scenarios around large-area skylights.

[0035] In one possible implementation, a baffle plate 5 is provided at the drain outlet 3.

[0036] An upward-extending baffle 5 is provided on the outside of the drain outlet 3. Its function is to prevent rainwater or splashing sewage from the external environment from flowing back into the drain channel. The baffle 5 can form a physical barrier, effectively preventing external water sources from entering the internal structure while maintaining unobstructed drainage.

[0037] The inclusion of baffle 5 enhances the overall system's drainage reliability under severe weather conditions such as heavy rain and strong winds, preventing increased load on the drainage system or backflow due to backflow. This design also improves the system's sealing and stability, increasing the safety margin for rainwater discharge.

[0038] In one possible implementation, the water collection tank 4, the square tube 1, and the baffle plate 5 are fixedly connected by welding.

[0039] The water collection tank 4, square pipe 1, and baffle plate 5 are fixed together by welding to form a complete and well-sealed drainage assembly. The welded connection eliminates the gaps caused by screws or plugs, improves the overall structural integrity of the system, and reduces the risk of loosening, displacement, or leakage between components.

[0040] Welding not only enhances the rigidity and stability of the structure but also improves the durability and corrosion resistance of the joints, making it particularly suitable for applications exposed to outdoor environments for extended periods. This method also reduces maintenance frequency, contributing to a longer overall system lifespan.

[0041] Instructions for Use: First, pre-install angle steel bases on the inner and outer sides of the skylight cover as the structural support foundation. Then, fix the square steel frame structure, consisting of the water collection trough 4, the water-retaining edge, and the square tube 1, to the angle steel bases by welding, ensuring overall structural stability and good sealing. After welding, cover the structure with a capping plate and fix it to the square frame with screws for additional compression and shielding. Finally, fill the gaps between the frame and the skylight cover with weather-resistant sealant to form an effective waterproof layer, preventing rainwater from seeping into the interior.

[0042] Before the skylight is officially installed, water can be injected into the water collection tank 4 to verify drainage. The water in the water collection tank 4 will flow into the square pipe 1 through the inlet hole and then smoothly discharge to the building roof through the drain hole. After confirming that the system's drainage function is normal, the main body of the skylight and the upper coping plate will be installed, and all gaps at the structural joints will be filled with weather-resistant sealant to ultimately form a double-sealed protection structure.

[0043] Tests conducted under simulated conditions demonstrate that, after installation and sealing, this rainproof structure significantly improves the drainage capacity of the skylight area, effectively preventing rainwater backflow or leakage. Using this structure can reduce the probability of leakage of the skylight under heavy rain conditions to zero, ensuring the dryness of the building's interior space and structural safety.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
