This invention provides a drainage collection device for building roofs, belonging to the field of water supply and drainage technology. It effectively solves the problem that current rooftop rainwater carrying a large amount of sand and soil increases the burden on subsequent filtration and treatment of collection devices. The technical solution includes an installation plate mounted on the exterior wall of the building. A rainwater pipe is vertically installed on the upper side of the installation plate. A flip plate is rotatably connected to the lower side of the rainwater pipe. A sliding frame is horizontally installed below the bottom output end of the rainwater pipe. A first sliding block and a second sliding block are horizontally slidably connected to the sliding frame. The first and second sliding blocks are fixedly connected by a connecting rod. A collection mechanism is connected to the first sliding block, and a discharge mechanism is connected to the second sliding block. The flip plate is connected to the first sliding block via a first linkage mechanism, and the discharge mechanism is connected to the second sliding block via a second linkage mechanism. The beneficial effect of this invention is that it provides a drainage collection device for building roofs that can automatically discharge rainwater containing a large amount of debris in its initial stage.

This invention discloses a ductless remote displacement dehumidification method and dehumidifier for large-space buildings, belonging to the field of building environmental humidity control technology. The method includes: the air to be treated sequentially flows through air filtration and refrigeration dehumidification treatment, then its pressure is increased to above 2 kPa by an ultra-high pressure EC fan, and after being stabilized by a flow equalization static pressure box, it is ejected from a long-neck nozzle at ultra-high dynamic pressure velocity, forming a remote displacement airflow. Based on the principle of mass, momentum, and static pressure conversion of air movement in a confined space in fluid mechanics, the remote displacement airflow actively adapts to the shape and size of the building space. Upon reaching the building's end wall, the dynamic pressure is converted into static pressure, forming a positive pressure center. This positive pressure center, combined with the negative pressure center at the dehumidifier inlet, creates a pressure difference, driving the return flow carrying humid air back to the dehumidifier inlet, completing a closed-loop dehumidification cycle. This invention also discloses a ductless remote displacement dehumidifier that implements the above method. This invention eliminates the need for duct installation, establishes an orderly airflow organization within a large building space, achieves remote displacement dehumidification, provides a large dehumidification coverage area, has a high energy efficiency, and can simultaneously filter dust or harmful gases.
