Description

Water screen nozzle assembly}

The present invention relates to a nozzle of a water screen capable of spraying water to form a fan-shaped water film.

When water is sprayed into the air at high pressure, a water stream may be formed in a specific shape according to a nozzle shape, and for example, a fan-shaped water film may be formed when the nozzle shape is flattened.

When an image is projected on the water curtain using an image projector, the image can be displayed on the water curtain like a movie theater screen, and the viewer can see the image.

As described above, a water film for expressing images is called a water screen.

Conventionally, the nozzles for forming the water screen are monotonous, and the water film is fixed in only one shape.

On the other hand, there is a technique of arranging several nozzles and spraying a fountain like mist to form a wall with water, but in this case, the image is not clear and the resolution is low, and an empty place where no water exists is formed. There is a problem that part of the image does not appear.

Therefore, there is a need for an improved water screen nozzle for a new type of special effect that can implement a higher resolution.

The first flange 32 may be fixed to the outer ring 24 of the bearing unit 20 . In addition, the first flange 32 may be formed in a circular ring shape with an empty center. As shown in FIG. 2, it can be arranged around the outer periphery of the nozzle flange 12 and not interfere with the nozzle flange 12.

As shown in FIGS. 2 and 5 , the cover 34 is fixed to the first flange 32 and may be disposed outside the nozzle assembly 10 . Also, as shown in FIG. 2 , the cover 34 may be disposed to cover a part of the nozzle gap t of the nozzle assembly 10 .

The second flange 36 is fixed to the cover 34 as shown in FIGS. 2 and 5 .

That is, in the nozzle of the water screen according to the embodiment of the present invention, the first flange 32, the cover 34, and the second flange 36 are formed in an approximate U shape to form a nozzle flange 12 and a nozzle cover ( 18) may be arranged to wrap around the outer circumference.

Therefore, the nozzle of the water screen according to the embodiment of the present invention, when water is sprayed through the nozzle gap t, can reliably block the water spray with the swing cover unit 30, so that the water is released according to the intention of the director. You can either let it spray or prevent the water from spraying.

As shown in FIG. 1 , the drive unit 40 may include a motor 42 , a first gear 44 and a second gear 46 .

The motor 42 outputs rotational power. In addition, the motor 42 may be a submersible motor or a waterproof motor, and may be a numerically controllable servo motor or DC motor.

The first gear 44 may be installed concentrically with the swing cover unit 30 from the outside of the swing cover unit 30 .

The second gear 46 is installed on the motor shaft of the motor 42 and meshes with the first gear 44 .

In the nozzle of the water screen according to an embodiment of the present invention, when the drive unit 40 operates, the rotational power is transmitted in the order of the motor shaft, the second gear 46, and the first gear 44 to form a swing cover unit 30 to rotate.

In addition, the motor 42 can precisely set or adjust the opening/closing angle of the swing cover unit 30 by numerical control.

The guide shaft 48 may be installed in the mount bracket 50, and a part may pass through the first gear 44 and be assembled into the guide hole 38 of the second flange 36.

As a result, the positions of the first gear 44 and the second gear 46 can be precisely aligned, and the first gear 44 and the second gear 46 can be properly engaged and assembled.

That is, the nozzle of the water screen according to the embodiment of the present invention is assembled so that the first gear 44 and the second gear 46 are engaged in an accurately aligned state, so that when the motor 42 is operated, the rotational power is in the middle. The swing cover unit 30 can be smoothly operated without jamming.

Hereinafter, the action of the nozzle of the water screen according to an embodiment of the present invention will be described with reference to FIG. 6 . Figure 6 is a view for explaining the action of the nozzle of the water screen according to an embodiment of the present invention.

In (a) of FIG. 6, the cover 34 is located on the upper side and covers the entire upper surface of the surface processing unit 14, and in this case, even if water is sprayed into the nozzle gap t, it is actually outside the cover 34 As a result, a water film is not formed.

6(b) is an example in which the opening angle a of the cover 34 is approximately 60 degrees. As a result, the water film w can form a 60 degree fan shape.

6(c) is an example in which the opening angle a of the cover 34 is approximately 90 degrees. As a result, the water film w may form a 90-degree fan shape.

6(d) is an example in which the opening angle a of the cover 34 is approximately 120 degrees. As a result, the water film w can form a 120-degree fan shape.

6(e) is an example in which the opening angle a of the cover 34 is approximately 180 degrees. As a result, the water film w can form a 180-degree fan shape.

That is, the nozzle of the water screen according to the embodiment of the present invention can form the water film to have an arbitrary fan angle according to the director's intention when forming the water film in a fan shape as shown in FIG. Video effects can be implemented.

On the other hand, although FIG. 6 describes an example in which the cover 34 is opened in a counterclockwise direction, an arbitrary fan-shaped angle of the water curtain may be implemented while being opened in a clockwise direction.
