Building ventilation shaft structure with rainproof function
The invention discloses a building ventilation shaft structure with a rainproof function. The building ventilation shaft structure comprises a shaftway, a guide pipe is arranged at the opening position of the upper end face of the shaftway, and a supporting rod is vertically and fixedly installed on the upper end face of the guide pipe. According to the building ventilation shaft structure, rainwater falls into a water collecting groove in the upper end face of a T-shaped heat conduction metal block and enters a first sliding cavity along a through hole, a first water absorption expansion ball pushes first pistons to move upwards after absorbing water, the two first pistons push a second piston to move upwards, the second piston drives the second piston to move upwards through a second guide rod, the second piston slides upwards along a negative pressure groove, negative pressure is formed on the lower portion of the second piston, then a fourth piston moves upwards, the liquid level of liquid below the fourth piston rises, liquid inside the guide pipe is pumped into a supporting rod, the lower end of a rotating bone is gradually close to the edge position of an opening in the upper end of the shaftway, the rainwater is prevented from entering the shaftway, the safe use of a fan is ensured, and the use cost is reduced.
本发明公开了一种具有防雨功能的建筑物通风井结构，包括井道，所述井道的上端面开口处设置有导管，所述导管的上端面的竖直固定安装有支撑杆。本发明，雨水落在T型导热金属块上端面的集水槽内，并沿着通孔进入一号滑腔内，一号吸水膨胀球吸水后会推动一号活塞向上运动，两个一号活塞会推动二号活塞向上运动，二号活塞通过二号导杆带动二号活塞向上运动，二号活塞沿着负压槽向上滑动，使得二号活塞下部分形成负压，进而使得四号活塞向上运动，进而使得四号活塞下方液体液面升高，进而将导管内部的液体抽入支撑杆内，使得转动骨的下端逐渐靠近井道上端开口的边缘处，避免了雨水进入，保证了风机的安全使用，减小了使用成本。
