To second head rope 3.12 of extension and the connection mesh sheet 3.13 of connection first head rope and second head rope.First head rope and lower head rope phase
Connection.
The setting of second iron chains is in connection mesh sheet.Second iron chains extends along the length direction of the lower head rope, and the second iron chains leans on
Nearly second head rope.
It is 2-3 meters to control the length away from bar, and it is 2.6 meters that the length away from bar is controlled in the present embodiment.Control is located at Culture pure seine away from bar
Inside.The one end of control away from bar is hinged on the first iron chains or is connected with the first iron chains by connecting rope.Control is away from the another of bar
End is connected with second head rope.
As shown in Figure 4, Figure 5, gasbag is connected with second head rope, leads between gasbag and second head rope in the present embodiment
Connecting line is crossed to be connected.Gasbag is equally spaced along second head rope.The sum of buoyancy of each gasbag sinks to the bottom purse seine more than second
The gravity of sinker device.
Hydraulic pressure triggering air bleeding valve includes being located at Master cylinder body 3.41 and valve pocket 3.45 on the outside of gasbag, connecting the interior of Master cylinder body
The exhaust pipe 3.44 of the inner cavity of chamber and gasbag, the cylinder piston 3.42 being slidably arranged in Master cylinder body and it is slidably arranged in valve pocket
Interior valve pocket piston 3.46.Exhaust pipe is tightly connected with gasbag.The internal diameter of Master cylinder body is more than the internal diameter of valve pocket.The of Master cylinder body
One end is equipped with intercommunicating pore 3.43.The second end of Master cylinder body is connected with one end of valve pocket.In Master cylinder body and positioned at cylinder piston with
It is equipped between the second end of Master cylinder body and pre-tightens compressed spring 3.47.Ring limit block 3.48, cylinder piston position are equipped in Master cylinder body
Between ring limit block and the first end of Master cylinder body.
When cylinder piston is against in the first end of Master cylinder body：Exhaust pipe be located at cylinder piston and Master cylinder body second end it
Between.
When cylinder piston is against in ring limit block：Exhaust pipe is between cylinder piston and the first end of Master cylinder body.
In Culture pure seine sinking watching（It sinks to before seabed）：
As shown in figure 4, Culture pure seine sinks under the action of the first iron chains；
Second iron chains and strip connection net gasbag buoyancy float downward, and by control away from bar hold；
When the first iron chains leans near Sea Bottom, since the internal diameter of Master cylinder body is more than the internal diameter of valve pocket, thus in the hydraulic pressure of extraneous seawater
Under effect, the active force for pre-tightening compressed spring will be overcome, so that cylinder piston is moved toward the second end of Master cylinder body, until cylinder piston
It is against in ring limit block, at this point, the gas in gasbag gradually passes through exhaust pipe, Master cylinder body and intercommunicating pore discharge.
As shown in fig. 6, after the first iron chains sinks to seabed, since the first iron chains is one continuous and can be according to sea
Bottom surface carries out fitting iron chains, can ensure that the lower head rope of Culture pure seine is bonded with seabed surface in this way, avoid in Culture pure seine
Fish the problem of being drilled out from net bottom；
More importantly：After the first iron chains sinks to seabed, since the gas in gasbag is gradually discharged, when in gasbag
After gas discharge to a certain extent, the second iron chains will sink under the effect of gravity；In the second iron chains sinking watching, control will away from bar
Gasbag and the second iron chains is driven to be rotated down toward the direction far from the first iron chains around the first iron chains, in this way when the second iron chains sinks
To seabed and after being fitted in seabed surface, the second iron chains can not only coordinate sea of the strip connection mesh sheet on the inside of Culture pure seine
The block line of other one of from-inner-to-outer is formed on bottom surface；And it can ensure that there is foot between the second iron chains and the first iron chains
Enough spacing（Spacing between second iron chains and the first iron chains will be controlled by controlling the length away from bar）If the first iron chains in this way settles
When there are the protrusion or other bulge-structures of engraved structure in seabed, the second iron chains can be enable across these bulge-structures, made
These bulge-structures are between the second iron chains and the first iron chains（These bulge-structures connect net covering by strip）, thus into
One step effectively avoids that passageway is walked in formation between the bottom of Culture pure seine and seabed surface, effectively avoids the fish in Culture pure seine
The problem of class is drilled out from net bottom.
