s3: the second winch system 2 and the third winch system 3 are activated to wind the circulation cable 4 and the bottom cable into the winches, respectively, thereby tightening the top and bottom openings of the fishing seine 5, and finally inside the fishing seine 5.
Optionally, the cultivation net cage is in a cuboid configuration. The top opening of the cultivation net box is square. The cable guide 6 is provided with four, is located the four angles of aquaculture net case top surface respectively.
Optionally, the cultivation net cage is in a columnar configuration.
The cable guide 6 is controlled to be opened or closed by an opening and closing device.
The top of the connecting rope 5-2 is provided with a lute head 5-3, and the bottom of the leading rope 4-2 is fixed with a shackle 4-3 corresponding to the lute head 5-3.
The first winch system 1 comprises a first winch 1-1, a first fairlead 1-2 and a first fairlead base 1-3.
The invention consists of a first winch system 1, a second winch system 2, a third winch system 3, a circulating cable 4, a fishing purse net 5 and a cable guide 6, as shown in figure 1.
Wherein the first winch system 1 comprises a first winch 1-1, a first rope guide 1-2, a first rope guide base 1-3, as shown in fig. 2. The second winch system 2 and the third winch system 3 correspond to the first winch system 1.
The circulation cable 4 is composed of a main cable 4-1, a lead 4-2 and a shackle 4-3, as shown in fig. 3 and 4. The fishing purse net 5 consists of a bag-free purse net 5-1, a connecting rope 5-2 and lute heads 5-3, as shown in figure 5. The fairlead 6 is shown in fig. 6.
When the platform is built, the following equipment needs to be installed according to the following requirements: the first winch system 1, the second winch system 2, the third winch system 3, the circulating cable 4 and the cable guide 6 are arranged on the aquaculture net cage, and can be welded or connected by bolts.
Wherein the first winch system 1, the second winch system 2 and the third winch system 3 are mounted on the main deck foundation in a position that is easy to reach and convenient to operate; the cable guide 6 is arranged at a corner of the culture net cage, and an operation platform and a vertical ladder are arranged around the cable guide; the circulating cable 4 passes through all the cable guides 6 and is connected at both ends to the first winch 1-1 and the second winch 2-1. Taking a quadrilateral culture net cage as an example, the installation is completed as shown in figure 3.
When the installation work is completed and the fishes in the culture net cages are mature, the fish collecting operation is started by using the fish collecting device.
The first shackle 4-3 of the fishing purse net 5 is pulled out of the second winch 2-1, and the first lute head 5-3 of the fishing purse net 5 is connected with the first shackle 4-3 of the endless rope 4. After the connection is finished, the first winch 1-1 is started to pull the circulating cable 4, the circulating cable 4 is pulled through the first winch 1-1 after a pair of lute heads 5-3 and shackles 4-3 are connected, the fishing purse seine 5 is gradually attached to the inner side wall of the aquaculture net cage under the traction of the circulating cable 4, and finally the first winch 1-1 is stopped. As shown in fig. 7 and 8. If the speed of the pulling rope is lower, the pulling rope can be fixed while being pulled.
Since the fairlead 6 is arranged at a corner of the cultivation cage, the circulation cable 4 can be turned in direction at the fairlead 6, so that a circulation can be formed along the inside of the cultivation cage, as shown in fig. 3. When the rope 4-2 of the circulating cable 4 runs to the fairlead 6 under the pull of the first winch 1-1, the rope 4-2 cannot pass through the fairlead 6. At this point, the rope 4-2 is manually passed through the opening of the fairlead 6. As shown in fig. 10. An operation platform which is easy for personnel to reach is required to be arranged at the cable guide 6.
After the fishing purse net 5 is placed, a third winch system 3 is used for lifting a bottom cable corresponding to the lower line of the fishing purse net 5, so that the bottom of the purse net is closed, and the fishes in the culture net cage are concentrated in the fishing purse net 5.
The second winch 2-1 is started, the circulation cable 4 is pulled, the opening of the cable guide 6 is opened, and the circulation cable 4 is tensioned so as to close the top opening of the fishing seine 5.
The adult fish may be harvested into a fishing vessel by means of a suction pump or an auxiliary crane or the like.
In addition, the shackles 4-3 of the circulation rope 4 can be opened one by one near the second winch 2-1 to separate the fishing seine 5 from the circulation rope 4, when adult fish is in the fishing seine 5, the upper and lower lines of the fishing seine 5 are tightened, and the fishing operation is completed. The bottom cable can then be disconnected from the fixing point and the third winch, so that the fishing seine 5 can be freely moved.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should be covered by the protection scope of the present invention by making equivalents and modifications to the technical solution and the inventive concept thereof.
