Nozzle changer
A nozzle changing device to remove and attach nozzles to a water shooting device is described. The device allows for removal and attachment of various nozzles on a water shooting device during or after a water display without the need for a technician to manually change the nozzles. The device may be independent or attached to the water shooting device.
1. A nozzle changing device for changing a nozzle attached to a water delivery device, comprising:
a holder that is located below a surface of a body of water and that includes at least two slots or tracks for receiving and releasably holding one or more nozzles, with at least one of the slots or tracks being empty to receive the nozzle attached to the water device;
one or more replacement nozzles releasably held in the slots or tracks; and
an arm operably coupled to the holder that moves axially and radially to move the holder under the surface of the body of water to thereby change the nozzle attached to the water delivery device.
2. The nozzle changing device of claim 1 , wherein the holder is coupled to the arm such that the movement of the arm causes the holder to move adjacent to the water delivery device, receive the nozzle attached to the water delivery device in the empty slot or track, and replace the nozzle with a replacement nozzle.
3. The nozzle changing device of claim 1 , wherein
the arm is movable axially to move the holder toward and away from the water delivery device and radially to rotate the holder to position one of the slots or tracks in alignment with the water delivery device.
4. The nozzle changing device of claim 1 , wherein the holder is circular plate.
5. The nozzle changing device of claim 4 , wherein the arm is coupled to the holder at or near the center of the circular plate.
6. The nozzle changing device of claim 1 , wherein each of the replacement nozzles is configured to provide a different water stream when attached to the water delivery device.
7. The nozzle changing device of claim 1 , wherein the arm is movably coupled to the water delivery device.
8. The nozzle changing device of claim 1 , further comprising:
a control device for controlling the movement of the arm.
9. The nozzle changing device of claim 1 , wherein the body of water is contained within a reservoir.
10. The nozzle changing device of claim 9 , wherein the reservoir has a bottom floor and the nozzle changing device is coupled to the bottom floor.
11. The nozzle changing device of claim 10 further comprising a frame that is coupled to the bottom floor that supports the nozzle changing device.
12. The nozzle changing device of claim 1 , wherein the holder is always located under the surface of the body of water.
13. The nozzle changing device of claim 1 , wherein the arm moves the holder from the first position to a position that is above the surface of the water to change the nozzle.
