| titleOfInvention | special dredger for sewer pipe |
| abstract | the invention relates to a sewer pipe dredging structure, in particular to a special dredger for sewer pipes, which comprises a dredging metal hose and a taper positioning plug sleeved outside the dredging metal hose; two ends of the dredging metal hose are respectively fixed with a two-way pipe joint and a three-way pipe joint; one end of the two-way pipe joint is fixed with the tail end of the dredging metal hose into a whole, and the other end of the two-way pipe joint is fixed with a plugging positioning mechanism; an air supply hose and a conductive cable are arranged in the dredging metal hose; one end of the conductive cable penetrates out of the third port of the three-way pipe joint and then is fixed with the plug joint into a whole, the other end of the conductive cable penetrates out of the plugging positioning mechanism and then is electrically connected with the electric heater, and the electric heater is positioned in the gas generator. The invention shortens the dredging time, has simple and easy operation, does not damage the pipe wall, reduces the dredging cost and improves the life quality. |
