Description

  The present invention relates to a pipe cleaning tool and a polishing nozzle used therefor. More specifically, the present invention relates to a pipe cleaning tool and a polishing nozzle used for polishing rust attached to the pipe.

  The miscellaneous wastewater is supplied to homes and factories via pipes. However, when a metal such as iron is used for the pipe, the pipe is corroded, which may narrow the cavity in the pipe and pinch the pipe. Further, the miscellaneous wastewater contains minerals such as calcium, and the above problem may occur even if the minerals are deposited in the pipe. For this reason, in order to keep piping in a suitable state, it is preferable to clean the piping at regular intervals.

  In general, piping is cleaned by removing water from the inside of the pipe, inserting a screw with a blade (blade) from one side of the pipe, and pulling the vacuum from the other side to rotate the screw, thereby causing rust and carbonate in the pipe. This is done by removing deposits such as calcium.

  However, since general piping is branched into a plurality of parts, in order to draw a vacuum, it is necessary to securely seal the outlet of each branch, and there is a problem that preparation is very troublesome. In addition, since the screw is rotated by the air flow generated when the vacuum is pulled, if the screw is caught in sediment in the pipe and the air flow is secured from the gap between the screws, the screw is then rotated. However, it is necessary to repeat the procedure of pulling out the screw once and securing the rotation of the screw and then performing polishing again, and there is a problem that the work efficiency decreases when the repeated work is repeated many times.

A rotating member that is rotatable by the fluid and that has a polishing member disposed around it and has a through-hole that discharges fluid, and is fixed to the shaft member and rotates between the shaft member and the rotating member. And a tip member that sandwiches the member.

  Moreover, the pipe cleaning tool according to the second means for solving the above problems includes a first polishing nozzle, a second polishing nozzle, a connecting pipe connecting the first polishing nozzle and the second polishing nozzle, The second nozzle is connected to the hose, discharges the fluid supplied from the hose from the first through-hole, and is connected to the connecting pipe to supply the fluid to the first polishing nozzle. A rotating member formed by a shaft member penetrating through the shaft member and being rotatable by a fluid discharged from the shaft member, a polishing member being disposed around the shaft member, and a second through hole for discharging the fluid being formed. A first member fixed to the shaft member and sandwiching the rotating member with the shaft member, and the first nozzle is connected to the connection pipe and discharges the fluid supplied from the connection pipe from the through hole.

By providing this through hole 311, fluid can be supplied to the inside of the rotating member 32, and the rotating member 32 receives this discharge and rotates. The direction of the through-hole 311 is not limited as long as the above effect is obtained, but it is preferable that the direction of the through-hole 311 is formed substantially parallel to a direction 316 perpendicular to the axial extending direction 315, for example. Here, “substantially parallel” means that it is completely parallel, but it means that a manufacturing error of about several degrees (for example, about 5 degrees) is allowed and included. The number of the through holes is not particularly limited, but it is preferable to receive a plurality of through holes, and it is preferable that the number is 2 or more and 6 or less.

  In addition, in this embodiment, although the raw material of the shaft member 31 is not limited as long as it can endure a high voltage | pressure, it is preferable to be comprised with metal materials, such as stainless steel, for example.

  In the present embodiment, the rotating member 32 in the second nozzle 3 has a substantially cylindrical shape, and a cavity is formed therein, and the cavity penetrates the shaft member 31. The rotating member 32 can be rotated by the fluid 8 discharged from the shaft member 31, and a polishing member 322 is disposed around the rotating member 32, and a through hole 321 for discharging the fluid 8 is formed.

  In the present embodiment, the cavity of the rotating member 32 may be near the center, but is preferably formed at an eccentric position. Here, “eccentric” means that the center of gravity is shifted in the plane of rotation (a plane perpendicular to the extending direction 315 of the shaft). By doing in this way, it becomes possible to shake a rotating member in the direction 316 perpendicular | vertical with respect to the extending | stretching direction 315 of a shaft member, and more powerful grinding | polishing is attained.
