Description

Technical Field

[0001] The utility model relates to the technical field of building ventilation structures, in particular to a passive green building ventilation structure. Background Art

[0002] As a commonly used passive green building ventilation device, the unpowered hood uses the natural wind speed in nature to drive the turbine rotation of the fan and the principle of indoor and outdoor air convection to accelerate and transform the air flow in any parallel direction into a vertical air flow from bottom to top, so as to improve the indoor ventilation effect. It does not require electricity, is noiseless, can operate for a long time, and removes indoor heat, moisture and foul air. It is rationally set on the top of the roof according to the natural laws of air and the principle of air flow, which can quickly discharge indoor heat and foul gases and improve the indoor environment.

[0003] The unpowered hood needs to be installed on the roof when in use. For example, a green building modular passive ventilation assembly structure is disclosed in the Chinese utility model patent with publication number CN220014249U. Through the cooperation of the limit assembly and the anti-slip ring, each slider at the side end of the annular plate is pressed down and slidably connected in the slide groove. When the annular plate contacts the slope rod, it pushes the slope rod and the insertion rod toward the cavity. When the insertion rod and the slope rod pass through the insertion hole at the side end of the annular plate, the spring will automatically push against The limiting plate drives the plug rod and the sloped rod to rebound. At this time, the sloped rod is limited in the insertion hole. At this time, the annular plate is assembled and fixed in the limiting circle. The anti-slip resistance of the anti-slip ring to the side end of the annular plate can improve the fixing effect of the limiting circle, thereby realizing the assembly of the non-powered hood for passive ventilation, and improving the installation efficiency of the hood. When disassembling, each pull plate is pulled outward so that the plug rod and the sloped rod leave the insertion hole, and the annular plate can be taken out to disassemble, repair or replace the hood, thereby improving the disassembly efficiency of the hood.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the above-mentioned modular passive ventilation assembly structure for green buildings, through the setting of the plug rods, ensures the convenience of installing the non-powered wind hood. However, since there are multiple plug rods and each plug rod is always moved close to the non-powered wind hood under the elastic action of the spring, when pulling out the plug rods, it is necessary to pull multiple plug rods at the same time, which increases the difficulty of disassembly for a single operator when disassembling the non-powered wind hood, and the mutual cooperation of multiple operators in disassembly increases the labor cost of disassembling the non-powered wind hood.
