Zusammenfassung: | PURPOSE:To enhance cleaning efficiency by providing a suction pipe with a suction pump, a horizontal section projected out of a main body and with an extension section furnished with a suction section out of the horizontal section, and thereby providing a vehicle with a drive device rotating the aforesaid suction pipe and with a telescopic mechanism moving the pipe back to a wall surface. CONSTITUTION:Downward ground contacting force is imparted by means of running water in a water channel 14 to a self-propelled vehicle main body 11 capable of travelling in the water channel 14 such as a closed conduit and the like, and the main body is provided with a suction pump 16 driven by a hydraulic motor 15 where a suction pipe 16a and an exhaust pipe 19 are connected to a suction pipe 18 and a discharge side respectively in fluid sealing relation. In the second place, a drive device 21 which permits the suction pipe 18 to be rotated around the axial line of a horizontal section 18a, is interposed between both bearings 20 and 20 where its stationary side is connected to a rotating side with a swivel joint 17 in fluid sealing condition. A suction mouth 27 is provided for the tip end of an extension section 18b which is bent into an elbow shape out of the horizontal section 18a to clean a wall surface 31 to be cleaned, with an inner cleaning brush 30. By this constitution, it is thereby possible to clean attachments and deposits over the wall surface and the like. |
