Description

Technical Field

[0001] The invention relates to the technical field of fishing nets, in particular to a process for self-adapting mesh adjustment of fishing nets. Background Art

[0002] The mesh of a fishing net refers to a pore structure formed by a designed mesh line. It is the basic structural unit of a net. The mesh is composed of mesh feet and knots, or mesh connection points. Mesh size generally refers to the mesh size of the net used in fishing operations, typically expressed as the diagonal length of the mesh foot or the length of the mesh foot. Different fish have different mesh sizes at different growth stages, and different fish species also have different body shapes. Adaptive mesh adjustment allows precise adjustment of mesh size for different target fish species and their growth stages, effectively capturing target fish, reducing empty net rates, and improving fishing efficiency.

[0003] When using fishing nets, first check that they are in good condition. Choose the appropriate handle and mesh size for the situation. Observe the target, approach slowly from the side and below, and tilt the net at a 30-45 degree angle. Quickly capture the prey and lift the net out of the water, avoiding injury when removing it. Clean and store properly after use. Be mindful of protecting aquatic resources, operate safely, and minimize environmental disturbances.

[0004] However, in the existing technology, some fishing nets will scoop up fish during use. Since there are fish of different sizes in the same water area, if the mesh size is too large, small fish will easily escape. If the mesh size is too small, it will increase the water resistance and reduce the scooping speed. Even if the net bag is too heavy, large fish will fall off the net when struggling, resulting in reduced fishing flexibility. Therefore, in order to address the above shortcomings, a fishing net mesh adaptive adjustment process is proposed to solve the above problems. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a self-adaptive mesh adjustment process for fishing nets, which solves the problem in the existing technology that some fishing nets cannot adjust the mesh according to the size of the fish to be caught during use, resulting in reduced flexibility.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Please see the attached Figure 1 , Attachment Figure 7 and attached Figure 8 , an embodiment of the present invention provides a process for adaptively adjusting the mesh size of a fishing net, including a handle 1. The handle 1 is a component held by an operator and is made of a non-slip and durable rubber material, which is convenient for the user to hold stably and provides a convenient force point for the entire operation process. The handle 1 is internally slidably connected to a support mechanism 2, which can slide inside the handle 1 to adjust its extended or retracted length to adapt to different fishing scenarios and operational requirements. The support mechanism 2 includes an adjustment rod 21, which plays a supporting and connecting role. The outside of the adjustment rod 21 is slidably connected to the inside of the handle 1, and the adjustment rod 21 is flexibly moved relative to the handle 1 through the restriction of the handle 1, so that the operator can adjust the position of the support mechanism 2 according to actual conditions. The inside of the adjustment rod 21 is fixedly connected to a positioning rod 22, which is fixed by welding to provide support for the positioning rod 22. The outside of the positioning rod 22 is rotatably connected to a rotating plate 23, and the rotating plate 23 can rotate around the positioning rod 22;

[0031] An opening plate 24 is fixedly connected to the left side of the rotating plate 23. The rotating plate 23 rotates around the positioning rod 22. After the rotating plate 23 drives the opening plate 24 to rotate to a vertical position, the opening plate 24 is used to support the fishing tackle, thereby increasing its flexibility. Elastic members 25 are fixedly connected to the front and back sides of the rotating plate 23. These elastic members 25 are made of rubber. When the rotating plate 23 rotates, the elastic members 25 deform and, when the external force disappears, they return the rotating plate 23 to its original position. The right end of the rotating plate 23 is rotatably connected to a rotating plate 26, which is supported by an axle, allowing it to rotate. A limit plate 27 is fixedly connected to the right side of the rotating plate 26 and secured by welding, providing support for the limit plate 27. A support cone 28 is fixedly connected to the right side of the limit plate 27. The support cone 28 has a sharp end, making it easy to insert into the ground for support, allowing it to act as an auxiliary sling and provide various functions. A plurality of limiting openings 29 are formed on the bottom side of the adjusting rod 21 . The limiting openings 29 are evenly distributed on the bottom side of the adjusting rod 21 and are square in shape.

[0032] Please see the attached Figure 2 -Attached Figure 4 The left side of the support mechanism 2 is fixedly connected to an adjustment mechanism 3, which is used to achieve adaptive mesh adjustment. The adjustment mechanism 3 includes an outer ring 34. The left side of the adjustment rod 21 is fixedly connected to the right side of the outer ring 34 and secured by welding, so that the movement of the support mechanism 2 can be transmitted to the adjustment mechanism 3. The right side of the outer ring 34 is fixedly connected to the left side of the support mechanism 2, further strengthening the connection stability between the outer ring 34 and the support mechanism 2, ensuring that the two do not move relative to each other during operation. The bottom side of the outer ring 34 is fixedly connected to the outer net 35, which has a relatively large mesh. The bottom side of the outer net 35 is fixedly connected to the chassis 36, which forms a relatively closed fishing space for the outer net 35 to prevent the fish from escaping from the bottom. The bottom side of the inner net 32 ​​is fixedly connected to the top side of the chassis 36. The inner net 32 ​​has a relatively small mesh. The mesh size can be adjusted by interlacing the inner net 32 ​​with the outer net 35. Two connecting blocks 33 are symmetrically arranged within the outer ring 34, slidingly connected to the inner surface. These blocks 33 slide along the inner wall of the outer ring 34, providing support and guidance for the movement of the inner ring 31. The inner ring 31 is fixedly connected to the adjacent sides of the two connecting blocks 33. The sliding of these blocks 33 drives the synchronous movement of the inner ring 31, thereby adjusting the shape of the inner mesh 32. The inner mesh 32 is fixedly connected to the bottom of the inner ring 31. Rotating the inner ring 31 adjusts the mesh size of the inner mesh 32, achieving adaptive mesh adjustment.

[0033] Please see the attached Figure 4 -Attached Figure 6A sliding plate 37 is slidably connected to the interior of the connecting block 33. The restraint of the connecting block 33 ensures stable sliding of the sliding plate 37. The interior of the outer ring 34 begins to have multiple square openings 38, which fit into the sliding plates 37. When the sliding plates 37 engage different square openings 38, they stabilize the position of the connecting block 33 and the inner ring 31, thereby determining the mesh size of the inner net 32. A reset assembly 39 is fixedly connected to the bottom side of the sliding plates 37, which resets the sliding plates 37. Both reset assemblies 39 include a rectangular stopper 391. The outer portion of the stopper 391 slides inside the square openings 38, allowing the stopper 391 to slide in and out of the square openings 38. The outer portion of the stopper 391 slides inside the connecting block 33, ensuring stable sliding of the stopper 391 within the connecting block 33 and providing guidance for its engagement with the square openings 38. Spring 1 392 is fixedly connected to the distal ends of the two limiting plates 391. Spring 1 392 provides elastic return force for the limiting plates 391. When an external force compresses spring 1 392, the limiting plates 391 can be disengaged from the square opening 38. After the external force disappears, spring 1 392 recovers its deformation, driving the limiting plates 391 into the square opening 38. The distal ends of the two springs 1 392 are respectively fixedly connected to the distal sides of the inner walls of the two connecting blocks 33. Securing spring 1 392 to the inner wall of the connecting block 33 provides stable support for spring 1 392, ensuring that its elastic force can effectively act on the limiting plates 391.

[0034] Please see the attached Figure 7 -Attached Figure 8 The right end of the handle 1 is fixedly connected to a sliding mechanism 4, which includes an anti-slip sleeve 41. The surface of the anti-slip sleeve 41 is usually provided with anti-slip grooves, which can increase the friction between the operator's hand and the handle 1 and prevent slipping during operation. The inside of the anti-slip sleeve 41 is fixedly connected to the right end of the handle 1, ensuring that the anti-slip sleeve 41 and the handle 1 become a whole and will not slide relative to each other during operation. The inside of the anti-slip sleeve 41 is slidably connected to a sliding ring 42, which can slide up and down inside the anti-slip sleeve 41 to prevent the sliding ring 42 from deviating. The top side of the sliding ring 42 is fixedly connected to a fixing plate 43, which plays a role of connection and fixing, ensuring the stability of the sliding ring 42 when sliding. The outside of the fixing plate 43 is slidably connected to the inside of the right end of the handle 1, so that the fixing plate 43 can slide inside the handle 1 together with the sliding ring 42, and at the same time guide the sliding direction of the sliding ring 42. The outer portion of the fixing plate 43 is slidably connected to the inner portion of the anti-slip sleeve 41. The restriction of the anti-slip sleeve 41 ensures the stability of the fixing plate 43 during sliding, thus ensuring the accuracy of its motion trajectory.

[0035] A connecting block 44 is fixedly connected to the bottom side of the inner wall of the sliding ring 42. The shape of the connecting block 44 is adapted to the limit opening 29. The outer portion of the connecting block 44 slides inside the multiple limit openings 29. When the connecting block 44 is engaged with different limit openings 29, the adjustment rod 21 can be fixed in the corresponding position, thereby determining the extension length of the support mechanism 2. A second spring 45 is fixedly connected to the bottom side of the sliding ring 42. The second spring 45 provides an upward elastic force for the sliding ring 42. When the operator releases the sliding ring 42, the second spring 45 can drive the sliding ring 42 to reset upward, causing the connecting block 44 to engage the limit opening 29. The bottom end of the second spring 45 is fixedly connected to the bottom side of the inner wall of the handle 1. Fixing the second spring 45 to the bottom side of the inner wall of the handle 1 provides stable support for the second spring 45, ensuring that it can properly perform its elastic reset function.

[0036] Please see the attached Figure 1 and attached Figure 8 The right side of the handle 1 is fixedly connected to a reinforcement mechanism 5, which prevents the net from tipping over or shifting due to external forces when the fishing gear is supported. The reinforcement mechanism 5 includes a concave plate 51, the left side of which is fixedly connected to the right side of the handle 1 and fixed by welding, thereby providing support for the concave plate 51. The concave plate 51 is internally rotatably connected to a rotating block 52, which can rotate inside the concave plate 51 to adjust the angle to adapt to different support environments. The right side of the rotating block 52 is fixedly connected to a connecting plate 53, which is fixed by welding, thereby providing support for the connecting plate 53. The right side of the connecting plate 53 is fixedly connected to a reinforcement cone 54. The reinforcement cone 54 cooperates with the support cone 28 and can be inserted into the soil to reinforce the net from different angles, thereby improving the stability of the net when used as an auxiliary fishing gear.

[0037] Working principle: According to the size of the fish school and the demand for fishing size, the sliding plate 37 is pushed to slide, and then the limiting plate 391 is driven to slide. During the sliding process of the limiting plate 391, the spring 1 392 is squeezed, so that the spring 1 392 can store elastic potential energy, and then a force in the opposite direction is applied to the limiting plate 391 to reset. When the limiting plate 391 slides away from the inside of the square opening 38, the inner ring 31 can be rotated, and then the two connecting blocks 33 are driven to rotate, and at the same time, the inner net 32 ​​is driven to rotate, so that the grids of the inner net 32 ​​and the grids of the outer net 35 are staggered. After the rotation reaches the adapted position, the pushing force on the sliding plate 37 is released, and the restoring force of the spring 1 392 is transmitted to the limiting plate 391 and the limiting plate is engaged with the inside of the square opening 38 for fixation, thereby achieving the function of net adjustment and improving its fishing flexibility.

[0038] When the handle 1 is not used for fishing, the rotating plate 23 is pushed to continue rotating around the adjusting rod 21, and at the same time, the elastic member 25 is squeezed and deformed, so that the rotating plate 23 can rotate, and on the contrary, the elastic member 25 can be engaged with the inside of the adjusting rod 21. As the rotating plate 23 rotates, the opening plate 24 is driven to rotate upward, so that it can provide support for the fishing rod, and then the rotating plate 26 is rotated, which in turn drives the limiting plate 27 to rotate, and finally drives the supporting cone 28 to rotate vertically downward and penetrate into the soil, so that the handle 1 and the adjusting rod 21 are in an inclined state, and then the rotating block 52 is pushed to rotate, and finally the reinforcing cone 54 is driven by the connecting plate 53 to rotate vertically downward and penetrate into the soil for reinforcement, so that it can achieve the effect of simulating auxiliary fishing gear, thereby improving its flexibility;

[0039] At the same time, by holding the anti-slip sleeve 41 and then applying a thrust to the fixed plate 43, the sliding ring 42 is driven to slide, and then the connecting block 44 is driven to slide and slide away from the inside of the limiting opening 29. At the same time, the sliding ring 42 will also squeeze the spring 2 45, so that the spring 2 45 can store elastic potential energy. At this time, the handle 1 and the adjusting rod 21 can slide to adjust the distance. After sliding to the corresponding position, the thrust on the fixed plate 43 is released, and the sliding ring 42 is pushed to slide by the restoring force of the spring 2 45, and then the connecting block 44 is driven to slide and get stuck into the inside of the limiting opening 29 for fixation, and then the adjustment is completed.
