Title:
Multi stage type diffused air device
Document Type and Number:
Japanese Patent JP6100123
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a multistage air diffusion apparatus by which an apparatus cost, a construction cost of the apparatus, or the like can be drastically reduced by reducing the number of air hoses to one.SOLUTION: There is provided a multistage air diffusion apparatus in which air diffusion nozzles 6a to 6c that make a multistage in a vertical direction in water are supported by a support member 4, and air fed by air hoses 8 from land is fed by switching to the air diffusion nozzles 6a to 6c of each stage. An intermittent rotation switching mechanism 10(A) that feeds air fed from a single air hose 8 by switching to the air diffusion nozzles 6a to 6c of each stage is provided. The intermittent rotation switching mechanism 10(A) intermittently rotates a main port 12a about one direction by feeding air pressure from the air hose 8 such that the main port 12a on the air hose 8 side matches one of sub ports 11a to 11c on the air diffusion nozzles 6a to 6c side of each stage.
