ト部７を備えている。(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings. In the drawing, 1 is a rotating nozzle, which includes a hollow nozzle base 2, a hollow rotating shaft 3, a cylindrical bearing 4,
It is composed of a hollow support 5 and a water injection nozzle 6. The hollow nozzle base 2 consists of a base body 2A to which the hollow rotating shaft 3 is connected, and a cap body 2C that is covered with the base body 2A to form a hollow part 2B.
The rotating shaft 3 is attached to the screwing side of the base body 2A.
and a cylindrical skirt portion 7 surrounding the tip of the cylindrical bearing 4.

る。 The front end surface 8 of the cap body 2C is made into a tapered surface, and three water injection nozzles 6 are located concentrically at equal pitches and are screwed in communication with the hollow portion 2B.
そして、この水噴射ノズル６の中心軸線は、回
転軸線に対し放射方向に所定の角度ｂ傾斜させる

20度(a)傾斜して装着されている。 The central axis of the water injection nozzle 6 is inclined at a predetermined angle b in the radial direction with respect to the rotational axis, and the central axis is tilted at a predetermined angle b in the direction opposite to the rotational direction of the nozzle base 2.
It is mounted at an angle of 20 degrees (a).
なお、上記傾斜角度(d)10〜20度の限定理由は、

ぼす力が低下して所期の目的を達することができ
なくなるからである。 The reason for limiting the above inclination angle (d) to 10 to 20 degrees is as follows.
If the angle is less than 10 degrees, the initial torque for rotation of the nozzle base 2 cannot be obtained, and therefore the rotation cannot be performed smoothly. Moreover, if it exceeds 20 degrees, the rotation becomes faster and the jet water spreads, and the force exerted on the wall surface, etc. of the jet water decreases, making it impossible to achieve the intended purpose.

A bearing washer 11 is installed to ensure that it can withstand the use of river water. Synthetic resin bearing washers suffer from severe wear and tear due to the pressure of the rotating parts, and are not durable.

とによつて消泡を行なうことができる。 According to the embodiment of the present invention, the jetted water is ejected from the tip of each nozzle 6 slightly outwardly at a predetermined angle (b) with respect to the rotation axis, and at an angle of 10 to 20 degrees in the opposite direction to the rotation direction. It is often ejected and collides with the wall surface etc. 14 in front of the nozzle. The hollow nozzle base 2 is automatically rotated by the reaction force of the collision of the jet water with the wall surface, etc., and the jet water from each nozzle 6 is spread over a wide range because the impact position moves sequentially. It collides evenly and exerts an effect on the wall surface etc. 14. Then, excavation is performed for muddy sand, sand and sludge removal is performed for sediment and sludge, and removal action is performed for adhering substances such as pollutants and garbage. Furthermore, bubbles generated on the liquid surface can be defoamed by being injected from above the water surface.

ができる。(Effects of the Invention) The rotary nozzle according to the present invention has a hollow nozzle base rotatably and in communication with a support body having a water flow passage, and a plurality of rotary nozzles are arranged concentrically on the front surface of the hollow nozzle base. The water injection nozzle is installed at a predetermined angle in the radial direction and at an angle of 10 to 20 degrees in the opposite direction to the rotation direction of the nozzle base, so the nozzle base rotates smoothly and the secondary water sprays onto the wall. Because it impinges evenly over a wide area, cleaning and excavation can be carried out reliably and efficiently, and not only tap water but also poor quality water such as river water can be used, making it suitable for a wide range of applications. I can do it. Also, when cleaning the inner surface of the tube, the entire circumference can be cleaned evenly.
Accumulated earth and sand can also be discharged smoothly and efficiently.
