A movable carriage having an electric motor, a speed retarder for said motor, a winding up wheel pivotally connected to the power shaft of said retarder and a control panel for said electric motor thereon is provided for enabling the successive hoisting and descending of the diffused aeration pipe apparatus.,下面是Diffused aeration pipe apparatus for use with an aeration tank专利的具体信息内容。

1. In an aeration tAnk having an air supply pipe mounted on a support adjacent one of the upper edges of said tank, an aeration piping system comprising: a. a first pipe having one end pivotably attached to said air supply pipe, the other end opening generally horizontally, b. a plurality of generally U-shaped pipes each having their ends pivotably jointed, one of said pipes having one end pivotably attached to said other end of said first pipe, c. aeration diffusion means attached to an open end of one of said plurality of pipes, d. means attached to said plurality of pipes adjacent each of said pivot joints to limit the angle of rotation between said joined pipes, e. means selectably engaging said first pipe to prevent said first pipe from moving relative to said supply pipe, f. guide means pivotably attached to said support, g. reversible rotating reel means, and h. a cable having one end attached to said reversible rotating reel means, the other end attached to the piping system and passing over said guide means.
2. The aeration piping system of claim 1 wherein the other end of said cable is attached to said aeration diffusion means.
3. The aeration piping system of claim 1 wherein said guide means is attached to said first pipe.
4. The aeration piping system of claim 3 wherein said other end of said cable is attached to said first pipe.
5. The aeration system of claim 1 wherein said reversible rotating reel means is attached to a carriage which is movable with respect to said piping system.
6. The aeration piping system of claim 1 wherein said means to limit the angle of rotation between adjacent joined pipes comprises mutually engaging levers, at least one lever attached to each pipe adjacent each joint.
7. The aeration piping system of claim 1 wherein said other end of the cable is removably attached to said first pipe.
8. The aeration piping system of claim 5 wherein said reversible rotating reel means comprises a reversible electric motor mounted on said movable carriage; a speed reduction gearbox having an output shaft attached to the output shaft of said electric motor; a take up reel mounted on said gearbox output shaft, said reel having one end of said cable attached thereto; and control means to control the direction of rotation of said electric motor.
