Large rainbow generating apparatus

30m large rainbow generator

This technology is about a large-scale rainbow generating device that can generate large, natural rainbows while minimizing components.

Generally, a rainbow is created when the observer turns his back to the sun and looks at a large group of water droplets, and the light refracted by the water droplets forms on the retina. If you spray water droplets by installing multiple water droplet spraying devices in a large area, you can create a group of water droplets with a large length and width. However, installing a water droplet spraying system including multiple water droplet spraying devices is very cumbersome and difficult to maintain, making it difficult to use in amusement parks or events.

This technology can create a natural large rainbow, such as by spraying water droplets with the spray guns arranged symmetrically left and right, giving the feeling of seeing a natural large rainbow in an empty field with just two guns.

Key Features:

• A unique structure that deploys two spray guns symmetrically to spray water droplets toward the upper center
• Each spray gun consists of a cylindrical housing, a high-performance blower mounted inside, multiple annular pipes arranged concentrically around the outlet end, and multiple nozzles installed in each pipe
• An anti-vortex member is installed inside the housing to prevent air vortices to maximize spray efficiency. In addition, the valve that controls the opening and closing of each annular pipe keeps the discharge water pressure constant, ensuring stable performance.
