The ball bearings 120a are arranged in a line along the upper surface of the bearing stabilizer 120. The ball bearing 120a is provided for a support structure in which the head part 300 can rotate with respect to the fixed trunk part 100.

The gasket 600 is mounted on each ball bearing 120a. The gasket 600 is located in the first channel 110 in the form of a flange, and a groove 610 is formed in the lower surface of the gasket 600 along the arrangement direction of the respective ball bearings 120a. Accordingly, when the gasket 600 is mounted on the ball bearing 120a, a bearing support structure is provided in which the ball bearing 120a comes into contact with the groove 610.

Also, the rotary plate 510 is mounted on the gasket 600. The rotating plate 510 is formed in the lower portion of the connecting pipe 520 integrally to form a connecting portion 500, that is, the upper rotating plate 510 is formed in the form of a flange, the lower portion of the connecting pipe 520 This extends downward.

Here, if the rotating plate 510 is located in the first channel 110, the connecting pipe 520 is fastened in the head portion 300 which passes through the lower end of the first channel 110 and positioned below it. Accordingly, the body part 100 and the head part 300 are connected by the connecting part 500, and at this time, the second water channel 310 formed in the head part 300 is connected to the first through the connecting pipe 520. It is in communication with the channel 110.

In addition, the head portion 300 has a cylindrical shape having a height of about 45 mm and an outer diameter of about 25 mm, and has a rounded lower end. In addition, a second channel 310 is formed in the axial direction, and the second channel 310 has a screw thread formed at an upper inner circumference to fasten an outer circumference of the connecting pipe 520.

At this time, each of the first injection grooves 320a is inclined at a predetermined angle with respect to the circumferential normal formed by the outer circumference of the head portion 300. According to the inclination of each of the first injection grooves 320a, the water jetted from each of the first nozzles 320 is jetted in the inclined direction along the first injection grooves 320a. Accordingly, the head part 300 rotates in a direction opposite to the jetting direction according to the principle of action-reaction by the jetting of water. (Shown in detail in FIG. 4)

4 is a cross-sectional view showing the propulsion force generating structure of the nozzle apparatus 1000 according to the present invention.

To reach. At this time, since the upper inner diameter of the second channel 310 is smaller than the upper inner diameter of the first channel 110, the pressure drops and the speed is relatively increased.

However, as the inner diameter of the lower portion of the second channel 310 is smaller, the speed is further increased, and the accelerated water is ejected through the nozzles 320 and 330 formed at both sides and the lower portion of the head 300. At the same time as the ejection, the first spraying groove 320a and the lower second spraying groove 330a are scattered while passing. At this time, since the first injection groove 320a is formed in a clockwise direction, the water jetting direction is clockwise while passing through the first injection groove 320a at a high speed.

Accordingly, the driving force is generated in the counterclockwise direction, and the head unit 300 tries to rotate along the counterclockwise direction opposite to the water jetting direction. At this time, the connecting pipe 520 and the head 300 is connected and the rotating plate 510 is provided with a rotation support structure in the first channel 110 by the gasket 600 and the ball bearing 120a. Head portion 300 may be rotated by the driving force in accordance with the water jet.

In addition, it is a matter of course that a hole in the outer periphery of the head portion 300 can be utilized as a spray nozzle separately from the propulsion force acquisition structure.

In addition to the structure in which the ball bearing 120a is interposed between the bearing set 120 and the gasket 600, the ball bearing 120a is integrally coupled between the outer ring and the inner ring via a ball bearing 120a or a roller, and the outer ring is the first channel 110. Coupling to the inner circumference of the) and the inner ring will be possible to use the structure of the rolling bearing used by fitting the outer circumference of the connecting pipe 520 of the connecting portion 500.

In addition, the bearing support 120 may be used by protruding the stepped to the boundary point of the upper surface and the inner circumference to prevent the ball bearing (120a) from being separated during assembly.

In addition to the method of reinforcing the coupling structure of the head portion 300 and the connecting pipe 520 by the fixing bolt 400, the connecting pipe 520 entered the pin into the second channel 310 of the head 300. Of course, it is possible to use a structure that penetrates into.

And the inclination angle is in addition to the above 45 °, if it is necessary to increase the rotational speed of the head portion 300 if necessary to increase the inclination angle to 50 ° ~ 80 ° or more, if it is necessary to reduce 10 ° ~ 40 Can be used within the range of °.

According to the rotary nozzle device for cleaning the tank according to the present invention as described above, since the washing can be performed throughout the inner wall of the tank 3000 by ejecting water while rotating, there is an advantage of improving the cleaning rate.

And the structure and shape is relatively simple, such as to obtain a driving force for rotation based on the water jet structure, there is an effect that is easy to manufacture and assembly.

In addition, since the nozzles 320 and 330 are not protruded to the outside but penetrated through the outer circumference of the head 300 having a predetermined inner diameter, the nozzles 320 and 330 may enter the tank 3000 having an inlet of a relatively small inner diameter. .
