    • An extended-reach sewer inspection device involving a hose-driven apparatus for progressively inspecting and cleaning the inside of a pipe at remote locations. The apparatus is comprised of a hose that has a nozzle apparatus which includes rearwardly-directed non-axial orifices such nozzle is attached to a forwardly-extending axially-aligned male member that has a female proximal end connected to the hose and a distal end opposite of the hose. A skid that includes a central body with at least three pipe-engaging runners connected to it and an axially-aligned opening dimensioned to freely receive the male member in such a manner as to allow the member to rotate freely within the skid. A retainer is secured to the distal end of the male member to hold it in the central-body opening, and a video camera is affixed to the central body whereby non-rotating video images are available to assist in the inspection and cleaning of a pipe.
    • 一种延伸的下水道检查装置,其包括用于逐步检查和清洁远程位置的管道内部的软管驱动装置。 该装置由具有喷嘴装置的软管组成,该喷嘴装置包括向后定向的非轴向孔,该喷嘴连接到前向延伸的轴向对准的阳构件,该阳构件具有连接到软管的阴性近端和与软管相对的远端 的软管。 包括具有与其连接的至少三个管接合流道的中心主体和一个轴向对准的开口,该开口的尺寸适于以允许构件在滑道内自由旋转的方式自由地容纳阳构件。 保持器固定到阳构件的远端以将其保持在中心体开口中,并且将摄像机固定到中心体,由此可以使非旋转视频图像有助于检查和清洁管道 。
