Description
Technical Field
[0001] This invention relates to the field of factory ventilation and waterproofing systems, and more particularly to a thin ventilation skylight system for factories. Background Technology
[0002] To ensure ventilation, typical factory skylight structures use water channels and valves on the roof, with the valves and channels alternating. Normally, the valves are open for ventilation, but close during rain or snow to drain rainwater through the channels. Commonly, the valves open and close by moving horizontally to close the gap between the valves and channels. However, this method has several drawbacks. First, rain and snow accumulate on the valves, leaking into the factory area when the valves are opened. Second, the horizontal drive mechanism of this type of valve requires frequent maintenance and has a short lifespan.
[0003] Common waterproof and skylight structures for factory roofs employ a combination of rain shields and waterproof channels. The rain shields block rain and snow, while some rainwater flows into the channel and drains away. The common method for installing these channels is by riveting and drilling, which is prone to rusting and leaks at the drilled holes. Later, a clamping installation method emerged, where the entire waterproof channel is clamped and fixed to a supporting beam. However, this method requires a clamping frame, which is cumbersome to install, has a complex structure, and low assembly efficiency. The clamping frame needs to be pre-assembled before being fitted with the waterproof channel, leading to high production and assembly costs. Furthermore, the connection between the clamping frame, the waterproof channel, and the supporting beam is often bolted, resulting in very low installation efficiency. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide a thin ventilation skylight system for factory buildings, which can solve the problems of high installation cost, complex assembly, and inconvenient operation of general factory roof waterproof lighting structures, as well as the problems of snow and water accumulation on the valve plate entering the factory area when the valve plate is opened, high maintenance frequency, and short service life caused by the use of horizontally driven valve plate structure.
