Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fishing net using buoyancy control, and its main object is to facilitate the operation of seine nets and fixed nets.

Trawl nets are made by attaching a float to one side of a long thin net and a weight to the other side, and fishing is carried out by dragging the bottom of the sea or river on the side with the weight attached, so there is a lot of resistance when pulling the net. So all I can do is enjoy the seine net. In addition, fixed nets require skill and labor as the net must be sunk flat on the ocean floor or riverbed and then quickly pulled up around the net when fish have entered, so traditional fishing nets are not suitable for recreational use by amateurs. has the disadvantage that it requires too much effort.

In view of the above, the present invention aims to popularize the operation of nets by utilizing the buoyancy of air and the weight of water.

An embodiment of the present invention will be explained using a seine net. In Fig. 1, 1 is a net, 2 is a reinforcing material using a thin plate of flexible plastic, etc. As shown in Fig.
Pass through the pipes 3.4, 3', 4' made of rubber or plastic to the string loops 9.9 on both sides of the reinforcing material 2, close the ends of each pipe, and close the base ends of the pulp 5. .6 and 5',
A rope 8 is forked and tied to the tip of the reinforcing material 2 on the opposite side of the pump 70, which enables blowing and suction through the pipe 6'. gear hole 1 with a pitch equal to the pitch of the winch gear.
1 is opened, a weight is tied to the small hole 12 of one of the reinforcing members, and when used, air is sent into the pipes 3, 4, 3', 4', the net is pulled out to the set position by boat or other means, and the weight is tied to the small hole 12 of one of the reinforcing members. If you open the pulp 5' and 6' of the pipe on the side where you attached the gauze (or reverse the pump to remove the air from the pipe, the weight side of the net will settle and the pipe on the other side will be filled with air. The net floats vertically.Also, in the case of small seine nets, a fourth layer is used as a reinforcing material.
As shown in FIG. 5 and FIG. 5, a sliding piece 14 having a connecting recess 16, a guide protrusion 17 in the center of one end thereof, and a groove 15 in which the guide protrusion fits on the opposite side of the guide protrusion, and a small In the connecting recess 16 of the unit connecting body 13, the string ring 9.9' is inserted into the hole 12.
Inserting the sliding piece 14 of another unit connector 13 and fitting the guide protrusion 17 into the groove 15 to connect the multiple unit connectors 13,
Pipes 3, 4, 3' and 4' are passed through the string ring 9.9' and tied to both sides of the net to serve as reinforcement material, and the reinforcement material is used to transport the net from land. It can also be pushed out towards the eye or pulled towards the pupil.

An example of a fixed network will be explained with reference to FIG. 9.
A reinforcing material 2 made of flexible plastic or the like is provided on the four sides of 8, and although not shown in the drawing, a weight is attached to the reinforcing material 2, and a pipe whose tip can be closed is made of rubber or plastic. 3.4, the foot pump 20 has a base end of the pipe that can freely rotate forward and reverse through the pulp 19.
It can be connected to create a fixed network.

The seine net constructed as described above is connected to the pump 7 and the pipe 3.
4. Send air to 3', 4' and pulp 5.6.5', 6'
When the net is closed, buoyancy is applied to both sides of the net, and the entire net is floated and pulled offshore using the rope 8. Since the buoyancy is acting on the entire net, pulling out the net is extremely easy.

After pulling out the net to the desired position, open 5.6' of the pipe on the side where the weight is attached and release the air, the side with the weight will sink and the side without the weight will rise. Therefore, the net becomes vertical and becomes a fishing state. When the lower part of the net touches the seabed or river bottom when the net is pulled toward the pupil side with a rope and is heavy, sending a small amount of air into the pipe on the weight side will cause the weight to rise a little and reduce the friction between the net and the seabed. The net becomes easier to pull.

In addition, if the seine net is small, unit connection body 1 shown in Figure 4
When using the reinforcing material connected to 3, when pushing the reinforcing material ＼ when sending the net out to sea, the connecting body 13 comes into contact with each unit as shown in Figure 6 and can be pushed out, and when pulling the net toward the pupil. is the seventh
As shown in the figure, the groove 15 of each unit connector 13 is locked by the guide protrusion 17 and does not separate, so the reinforcing material can be pulled into a rope, making it suitable for recreational use by several people. Also, in the case of a fixed net, if air is put into pipe 3.4, the net will float, so the net will be placed in the designated position and the air in the pipe will be removed (and the net will sink due to the weight, and when the net is pulled up, air will be forced into the pipe). When the net is fed, the four sides of the net rise up, eliminating the need for manual effort to pull it up. When pulling up the net, switch the pulp and send air through the pipe to drain the water and give buoyancy to the net.

The above is a case where the pipe is attached to the reinforcing material, so it is possible to use a thin pipe, but if you use a long, sharp pipe, you can get the same effect even if you connect the pipe and the net directly without using any reinforcing material. You can change your expectations.
