In order to realize the above-mentioned purpose, the utility model provides a nuclear power plant radioactivity laundry room pipeline dredging tool, including outer hose, inner hose, high pressure nozzle, solid fixed ring, the upper portion of the horizontal section of pipeline is equipped with one and goes up the access hole, goes up the access hole and is furnished with one and goes up sealed lid, and outer hose is in the horizontal section that outer hose from last access hole stretched into the pipeline, and the external diameter of outer hose equals 1/2-7/10 of pipeline internal diameter, the inside inner hose that is equipped with of outer hose, the outlet end of inner hose even have a hard pipe, and the tip of hard pipe exposes the outside of outer hose, and a high pressure nozzle is installed to the tip of hard pipe, and hard pipe and inner hose outside all link to have solid fixed ring, and solid fixed ring is fixed mutually with the inner wall of outer hose.

Preferably, the water inlet end of the inner hose is positioned outside the outer hose, and the water inlet end of the inner hose is connected with a high-pressure water supply device.

Preferably, the upper access hole is arranged in an inclined mode, and the inclined direction of the upper access hole from top to bottom is consistent with the water flow direction of the transverse section of the pipeline.

Preferably, the lower part of the transverse section of the pipeline is provided with a lower access hole, the lower access hole is positioned below the upper access hole, and the lower access hole is provided with a sealing cover.

Preferably, the water column sprayed by the high-pressure spray head inclines downwards.

Preferably, a plurality of cameras are fixed in the outer hose, and the cameras are close to the spray head.

The utility model has the advantages that: the high-pressure spray head is arranged at the end part of the hard pipe, so that the blocked part of the pipeline can be dispersed by high-pressure water flow, and the pipeline becomes smooth; the arrangement of the outer hose enables the tool to be difficult to retreat due to the reaction force in the using process, and the using effect of the tool is guaranteed.

The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.
