At the moment, the whole lifting type aquaculture net cage has certain pressure on the seabed 17.
The utility model discloses a fishing operation working process of over-and-under type aquaculture net case as follows:
when the fishing operation is prepared, the lifting aquaculture net cage is suspended in water or is sunk on the seabed 17, the air inlet end of the air inlet pipe 100 on the upper variable-volume buoyancy chamber 05 is connected with a pipeline on the air outlet end of a vacuum compressor 700 on a ship through a quick connector 500, and the vacuum compressor 700 is started to press compressed air into the air inlet pipe 100 on the upper variable-volume buoyancy chamber 05. Since the check valve 600 is provided on the exhaust pipe 300, the check valve 600 is in a closed state under the pressure during the air compression process, and the exhaust of the exhaust pipe 300 is prevented. With further air compression of the upper variable-volume buoyancy chamber 05, the air in the upper variable-volume buoyancy chamber 05 is increased, the pressure in the upper variable-volume buoyancy chamber 05 is increased, seawater in the upper variable-volume buoyancy chamber 05 is gradually drained outwards through the upper drainage pipe 200 (even though the seawater is gradually drained outwards) until the seawater is in an empty chamber state (namely when the seawater in the upper variable-volume buoyancy chamber 05 is emptied), the air inlet pipe 100 is always in a working state, at the moment, the aquaculture box body rises to be in a top exposed floating state as shown in fig. 7, at the moment, the constant-volume buoyancy chamber 04 is still positioned at the upper limiting rod 131, the whole aquaculture box body is in the top exposed floating state, the constant-volume buoyancy chamber 04 still floats at the top of the aquaculture box body, and at the moment, the highest point of the lifting aquaculture net cage is exposed to about 1m (namely 0.5m, 0.8m, 1.2m and 1.5 m).

Along with further compressing air to the lower variable-volume buoyancy chamber 06, the air in the lower variable-volume buoyancy chamber 06 is gradually increased, the pressure of the lower variable-volume buoyancy chamber 06 is gradually increased, seawater in the lower variable-volume buoyancy chamber 06 is gradually drained outwards through the upper drain pipe 200 (even if the seawater is gradually drained outwards), the air inlet pipe 100 is always in a working state, at the moment, the lifting type aquaculture net cage continues to be in an upward floating state, the constant-volume buoyancy chamber 04 and the aquaculture box body move relatively, and the constant-volume buoyancy chamber 04 does not slip downwards away from the sea level 16 under the action of self gravity and seawater buoyancy.

Along with the further progress of the fishing operation, the caught objects in the lifting type aquaculture net cage are reduced (namely, the aquaculture objects in the netting box body 02), the floating height of the lifting type aquaculture net cage does not meet the requirement of the fishing operation, and the fishing operation is stopped. At this time, the operation of removing the safety adjusting device 14 is carried out (i.e. the rotating cross rod 142 of the safety adjusting device 14 on the top surface of the constant volume buoyancy chamber 04 rotates out and is separated from the position under the stop rod 141), the constant volume buoyancy chamber 04 is removed from being matched and fixed with the frame 01, the vacuum compressor 700 increases the pressure of compressed air on the lower variable volume buoyancy chamber 06, the lower variable buoyancy chamber 06 continues to discharge water outwards through the water discharge pipe 200, the lifting type aquaculture net cage continues to float upwards, the constant volume buoyancy chamber 04 slides downwards until the requirement of the fishing operation state is met again (i.e. the distance between the sea level 16 and the bottom pipe frame 08 is 0.75-0.8m, the operation needs on-site water level observation and micro-control of the vacuum compressor 700), the lower variable buoyancy chamber 06 continues to be subjected to pressure compression on the current time, and the operation of the safety adjusting device 14 is restarted (i.e. the rotating cross rod 142 of the safety adjusting device 14 on the top surface of the constant volume buoyancy chamber 04 rotates into the position under the stop rod 141, the rotating cross rod 142 is matched with the stop rod 141), and then the constant volume buoyancy chamber 04 is matched and fixed with the frame 01, and the fishing operation is started again.
