内周面に高圧水を噴射して洗浄する管内洗浄ノズルに関
するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-pipe cleaning nozzle for injecting high-pressure water onto the inner peripheral surface of a pipe such as a water distribution pipe for cleaning.

なりつつある。2. Description of the Related Art Conventionally, this type of in-pipe cleaning nozzle is divided into two types, one that rotates (rotates) the injection port (rotating type) and the other that does not (fixed type). Since it hits only a part of the inner peripheral surface of the pipe, and uneven cleaning may occur, the rotating type is becoming the mainstream.

まうという不都合があった。However, in this rotary type in-pipe cleaning nozzle, the injection port is rotated by the reaction force when the high-pressure water is ejected from the injection port. Therefore, the cleaning force should be increased. When the pressure of the high-pressure water is increased, the number of rotations of the injection port also increases, and the high-pressure water discharged from the injection port becomes mist, which rather reduces the cleaning power.

ノズルには不向きである。In order to eliminate such an inconvenience, a method of decelerating the injection port by combining gears can be considered, but in that case, the mechanism becomes complicated and the device becomes large, so that not only the cost rises but also It is not suitable for running type pipe cleaning nozzles.

Here, each rotary jet port 6 is provided at an angle inclined with respect to the radial direction of the rotating part 5, and the two rotary jet ports 6A and 6C facing each other have the remaining two rotary jet ports 6B and 6D. The inner diameter is larger. Furthermore, as shown in FIG.

ら高圧水が勢いよく吐出する。Since the in-pipe cleaning nozzle 1 has the above-described structure, when cleaning the inner peripheral surface of a pipe (not shown) such as a water distribution pipe, the in-pipe cleaning nozzle 1 is connected to a water supply hose (not shown). ), And supplies high-pressure water from the water supply hose to the water passage 3 of the nozzle shaft 2. Then, high-pressure water is vigorously discharged from each of the rotary jet ports 6A, 6B, 6C, 6D of the rotary unit 5 and each of the rear jet ports 7.

Since a couple is generated in the rotating portion 5, the rotating portion 5 rotates in the arrow L direction due to the reaction force. On the other hand, high-pressure water is discharged rearward from the rear injection port 7, so that the reaction force causes the in-pipe cleaning nozzle 1 to advance in the pipe together with the water supply hose. As a result, the high-pressure water discharged from each rotary jet port 6 and each rear jet port 7 of the in-pipe washing nozzle 1 is discharged in a spiral shape and strongly hits the entire inner peripheral surface of the pipe. It is cleaned uniformly without causing uneven cleaning.

防止することができる。By the way, when the rotating portion 5 of the in-pipe cleaning nozzle 1 rotates, the centrifugal force generated by the rotation causes the four braking pins 1 to rotate.
Since 0 projects outward in the radial direction of the rotating portion 5 and abuts on the inner peripheral surface of the nozzle end 11, frictional resistance is generated at the abutting portion and the rotational speed of the rotating portion 5 is suppressed. Since this frictional resistance increases as the rotation speed of the rotating unit 5 increases, even if the pressure of the high-pressure water is increased in order to increase the cleaning power, it is possible to suppress the speeding up of the rotating unit 5 associated with it. As a result, it is possible to avoid the problem that the high-pressure water is atomized due to the high-speed rotation of the rotating unit 5, and it is possible to increase the cleaning power according to the increase in pressure of the high-pressure water. Moreover, since the high-pressure water supplied from the water supply hose to the water passage 3 is also supplied to the tip portions of all the braking pins 10, the friction heat generated at the contact portion between each braking pin 10 and the nozzle end 11 is eliminated. It is possible to prevent it from being seized.

It is mounted and the nozzle ends 11 are located outside of these braking tips 13. Further, two water conduits (not shown) are formed on the front surface of the rotating portion 5 so as to communicate with the water conduit 3 of the nozzle shaft 2, and if there is water in the water conduit 3, this water conduit 3 Will be supplied to the outside of each braking tip 13 through each of the water conduits. Other configurations are the same as those in the first embodiment.

Since it moves while rotating, the inner peripheral surface of the pipe is uniformly washed with high-pressure water. At this time, the two braking tips 13 are opened by the centrifugal force due to the rotation of the rotating part 5 of the in-pipe cleaning nozzle 1 and abut against the inner peripheral surface of the nozzle end 11, so that frictional resistance occurs and the rotating part 5 rotates.
