11 connection of end.
A kind of folding and unfolding method adapting to uneven water-bed bottom-sitting type underwater platform, comprising the following steps:
Step 1: a certain number of plastic floating balls will be installed on rigid support 1, platform is drawn to cloth with workboat and is discharged water
Domain；
Step 2: starting air compressor machine 10 is supplied to salvaging in bucket 4, and the water salvaged in bucket 4 is gradually forced out, until sitting bottom
Formula underwater platform buoyancy increases until itself floatability is in the water surface, during gas supply, if 4 edge of bucket is salvaged in discovery to be had largely
Bubble is emerged, then stops being that the salvaging bucket 4 continues to supply by controlling terminal 11, run until stopping air compressor machine 10；
Step 3: workboat hangs platform, releases plastic floating ball, opens end normally closed solenoid valve 5, salvages gas in bucket 4
Discharge, platform start the fashionable closing end normally closed solenoid valve 5 that sinks, and platform has lesser negative buoyancy force at this time, passes through workboat
Underwater platform cloth is slowly put into the bottom；
Step 4: after platform is bottomed, opening end normally closed solenoid valve 5, salvages gas emptying, platform negative buoyancy force in bucket 4
Highest is reached, platform is completed and is tethered at.
When needing to overhaul or other need to recycle on platform, comprising the following steps:
Step 1: being arranged necessary construction warning mark, indicates operation area range, and workboat is only placed on construction area
Swim side；
Step 2: being the gas supply of underwater salvage bucket 4 by air compressor machine 10, and gas is forced out the water of underwater salvage bucket 4 gradually,
Platform buoyancy is gradually increased to positive negative force (during gas supply, to be had a large amount of bubbles to emerge, leads to if 4 edge of bucket is salvaged in discovery
Cross controlling terminal 11 and stop being that the salvaging bucket 4 continues to supply, run until stopping air compressor machine 10), platform leaves water-bed and emersion
(in platform floating-upward process, due to variation in water pressure, 10 edge of air compressor machine constantly has gas to emerge to be normal phenomenon, is not necessarily to the water surface
Control)；
Step 3: after platform emerges, stage+module certain amount plastic floating ball；
Step 4: platform is drawn to bank or maintenance dock with workboat.
The above embodiments are only the preferred technical solution of the present invention, and are not construed as limitation of the invention, this hair
Bright protection scope should be with the technical solution of claim record, technical characteristic in the technical solution recorded including claim
Equivalents are protection scope.Equivalent replacement i.e. within this range is improved, also within protection scope of the present invention.
