458 results about "Vertical segment" patented technology

A vertical line segment is a portion of a line that is entirely vertical; that is, both vertices that make up the segment's endpoints have the same x- and y-coordinates but different z-coordinates. Vertical line segments may be individual features, or they may be contained in features that have other segments that are nonvertical, composing a hybrid polyline.

Submergence type lift aeration apparatus

The invention provides a suspending type lifting aeration device, which mainly comprises an aerator communicated with an external air supply through an air inlet pipe and an air bag type or pipe type floating drum connected with the aerator; the aerator is also provided with a lifting positioner which can realize the lifting positioning of the aerator and is provided with a lifting wire rope; the aerator is formed by the combination of at least two pipe type or disk type micropore aerators which are communicated with the soft air inlet pipe through air inlet branch pipes; the air bag type or pipe type floating drum is communicated with the external air supply through an air inlet-outlet hose; the lifting positioner at least comprises a set of pulley components and a lifting wire rope; and the pulley components also comprise positioning wheels arranged on the side part and the bottom part of a sewage reservoir, and by the pulley components and the positioning wheels, the lifting wire rope forms a vertical segment on the side part of the sewage reservoir, a horizontal segment on the bottom part of the sewage reservoir and a vertical segment below the aerator and is finally connected with the lower part of the aerator. The lifting aeration device has the characteristics that the lifting aeration device has simple structure and convenient use, and the aerator is made to suspend in the sewage reservoir, so that the positioning and the maintenance of the aerator are convenient, the project can be conveniently, continuously and stably operated for a long time, the use cost is lowered and the sewage treating effect can be improved.
