Negative-pressure dust collection type building foundation pit guardrail
The invention discloses a negative pressure dust collection type building foundation pit guardrail. The guiderail comprises a vertical rod fixedly connected to the upper end of a base; a conical plateis fixedly connected to the lower portion of the inner wall of the vertical rod, a vertical plate is fixedly connected to the inner top of the vertical rod and the upper end of the conical plate, theinterior of the vertical rod is divided into two dust collection cavities and an exhaust cavity through the conical plate and the vertical plate, a vertical rod is rotatably connected to the upper end of the vertical rod, and a plurality of impellers are fixedly connected to the upper portion of the side wall of the vertical rod. The inner wall of the vertical rod is divided into the dust collection cavities and the exhaust cavity through the vertical plate and the conical plate; when wind blows outside, the impellers drive a cross rod to rotate through the vertical rod; the cross rod continuously skims over a sliding plate; the sliding plate continuously slides on the inner wall of the exhaust cavity under the effects of magnetic repulsion between a first magnet and a second magnet and aspring, air in the dust collection cavities is exhausted, negative pressure exists in the dust collection cavity, dust flying in the air is absorbed, and the situation that the dust is inhaled by constructors and harms the physical health of the constructors is avoided.
本发明公开了一种负压吸尘式建筑基坑护栏，包括固定连接在底座上端的立杆，所述立杆内壁下方固定连接有锥形板，所述立杆内顶部与锥形板上端固定连接有竖板，且所述锥形板和竖板将立杆内部分为两个吸尘腔和一个排气腔，所述立杆上端转动连接有竖杆，所述竖杆侧壁上方固定连接有多个叶轮。本发明通过竖板和锥形板将立杆内壁分为吸尘腔和排气腔，在外界起风时，叶轮通过竖杆带动横杆转动，使得横杆不断的掠过滑板，使得滑板在第一磁铁与第二磁铁之间的磁斥力和弹簧的作用下不断的在排气腔内壁滑动，对吸尘腔内的气体进行排出，使得吸尘腔内存在负压，对飘扬在空气中的灰尘进行吸收，避免灰尘被施工人员吸入，危害施工人员的身体健康。
