PURPOSE: To provide a device for completely recovering and removing foreign matter sticking to the interior of a pipe while scraping the foreign matter. CONSTITUTION: A support member 10 is fixed to the main body 2 of a traveling frame 1 moving inside a pipe 30. In addition, a head 12 for removing foreign matter sticking to the inner wall of the pipe 30 is attached to the tip of an arm 11 which is freely expandable in an orthogonal direction with the shaft core of a rotatary shaft 4 for the support member 10 and is pressed against the inner wall surface 31 of the pipe 30 with a specified pressing force. Further, a cylindrical recovery duct 16 interlocked with the arm 11 and freely expandable is arranged in the arm 11. On the other hand, the support member 10 communicating with the recovery duct 16 is connected to a discharge duct 17 behind a guide hole formed on the rotating shaft 4. Thus, it is possible to prevent the water being fouled by the scraped foreign matter or sludge to the maximum allowable extent. Besides, it is possible to maintain a strict observation of the operation and, at the same time, prevent the foreign matter from being insufficiently scraped off. In addition, the foreign matter is totally recovered to an outside recovery device, so that it is so longer almost entirely flown into the ocean and the river. Thus, the problem of an environmental pollution in the ocean and the river can be solved and the operating efficiency can be enhanced. |
