Description

Technical Field

[0001] The utility model relates to the technical field of fishery catching, and more specifically to a multifunctional fishery catching net. Background Art

[0002] Fishing nets are indispensable fishing tools in fishery production. There are many types of fishing nets, which can be selected according to different fishing environments. Among them, trawl nets are a type of fishing net. It is a fishing method that uses fishing boats to drag fishing gear forward on the seabed or in the sea water. It uses the power of the fishing boat to force the fish, shrimp, crabs and other fishing objects in the waters where the fishing gear passes into the net bag, thereby achieving the purpose of fishing. Trawl operations are characterized by flexibility, strong adaptability and high production efficiency. They can not only catch fish, but also marine life such as cephalopods, shellfish and crustaceans.

[0003] Based on the above, the inventors found that a buoy is installed at the top of the opening of the existing trawl net bag to expand the net bag and improve the fishing efficiency. However, the buoy is directly exposed to the outside, and when the net bag moves on the seabed, it is easy to cause rocks on the seabed to float, thereby colliding with the buoy. Over time, the buoy is damaged, resulting in the net bag cannot be fully opened, affecting the fishing effect. Therefore, in view of this, the existing structure is studied and improved to provide a multifunctional fishing net, in order to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a multifunctional fishing net. In this scheme, a protective component is arranged to protect the buoy of the fishing net, so as to prevent the stones that are collided and knocked away during the movement of the fishing net from directly impacting the buoy, thereby reducing the damage of the buoy and ensuring the fishing effect. In addition, a rotating component is arranged to eliminate part of the impact force through the rotation displacement of the protective component, and at the same time reduce the displacement resistance, thereby further improving the protection effect of the protective component.

[0026] Example:

[0027] See also Figure 1-4 A multifunctional fishing net comprises a net bag 1, the front end of the net bag 1 is fixedly connected to side plates 2 on both sides, and the front end of the net bag 1 is fixedly connected to a bottom rod 4 on the bottom surface, a group of rollers 6 are arranged on the outside of the bottom rod 4, a group of support rods 3 are fixedly connected to the top surface of the front end of the net bag 1, a pair of protective covers 5 are clamped on the outside of the support rods 3, and a floating ball 7 is arranged on the top of the support rods 3, a clamping groove 8 is opened on the side of the middle part of the support rod 3, a rotating mechanism 9 is arranged inside the clamping groove 8, the bottom ends of the two protective covers 5 are fixedly connected to clamping sleeves 10, and a pair of threaded rods 11 are fixedly connected to the inner side of one of the clamping sleeves 10;

[0028] The rotating mechanism 9 includes a connecting sleeve 12, positioning holes 13 are opened on both sides of the lower side of the connecting sleeve 12, and both ends of the connecting sleeve 12 are fixedly connected with movable rings 14, and the end surface of the movable ring 14 is movably connected with a group of balls 15. The rotating mechanism 9 is provided to make the protective cover 5 rotate when subjected to force and reduce the impact force.

[0029] See also Figure 1 The bottom rod 4 is arranged in a concave shape, and the bottom rod 4 passes through the roller 6, and the roller 6 is movably connected to the bottom rod 4. The tugboat puts the net bag 1 into the river channel through the winder, and the side plate 2 and the roller 6 are in contact with the riverbed. The side plate 2 ensures the opening width of the net bag 1, and the roller 6 prevents the net bag 1 from rubbing against the stones of the riverbed during movement, thereby reducing the friction damage of the net bag 1.

[0030] See also Figure 3 The protective cover 5 is arranged in a mesh shape, and the two protective covers 5 are arranged symmetrically. The two protective covers 5 are symmetrically fixedly connected to the outside of the floating ball 7 to protect the floating ball 7.

[0031] See also Figure 2 The float 7 is located on the inner side of the protective cover 5, and the top of the float 7 is threadedly connected to the support rod 3. The float 7 drives the opening of the net bag 1 to stretch upward to ensure the opening height of the net bag 1.

[0032] See also Figure 4 The connecting sleeve 12 is sleeved on the outside of the clamping groove 8, and the connecting sleeve 12 and the movable ring 14 are movably connected to the clamping groove 8. The connecting sleeve 12 drives the movable ring 14 to rotate inside the clamping groove 8, and eliminates part of the impact force through displacement.

[0033] See also Figure 4 One side of the ball 15 passes through the end face of the movable ring 14 and fits with the inner surface of the clamping groove 8. When the movable ring 14 rotates, the ball 15 rubs against the inner surface of the clamping groove 8, thereby rotating and reducing the rotational friction of the movable ring 14.

[0034] See also Figure 4 The threaded rod 11 on the inner side of the clamping sleeve 10 passes through the positioning hole 13 and the other clamping sleeve 10, and one end of the threaded rod 11 is threadedly connected with a nut. First, the float 7 is threadedly connected to the support rod 3, and then the two clamping sleeves 10 are symmetrically clamped on the outer side of the connecting sleeve 12, so that the threaded rod 11 passes through the positioning hole 13 and the other clamping sleeve 10, and is fixed by the nut.

[0035] When in use: first, thread the float 7 and the support rod 3, then symmetrically clamp the two clamping sleeves 10 on the outside of the connecting sleeve 12, so that the threaded rod 11 passes through the positioning hole 13 and the other clamping sleeve 10, and is fixed by a nut, and the two protective covers 5 are symmetrically fixedly connected to the outside of the float 7, and then the tugboat puts the net bag 1 into the river channel through the winder, and the side plate 2 and the roller 6 are in contact with the riverbed, and the side plate 2 ensures the opening width of the net bag 1, and cooperates with the buoyancy of the float 7 to drive the opening of the net bag 1 to stretch upward to ensure the opening height of the net bag 1, thereby ensuring the fishing effect of the net bag 1, and the roller 6 allows the net bag 1 to avoid the movement of the net bag 1. To avoid friction with the rocks on the riverbed and reduce friction damage to the net bag 1, when the net bag 1 is moving, the roller 6 and the side plate 2 may collide with the rocks, causing the rocks to hit the float 7. At this time, the float 7 is protected by the protective cover 5, and the protective cover 5 is subjected to force, so that the connecting sleeve 12 drives the movable ring 14 to rotate inside the clamping groove 8, and part of the impact force is eliminated through displacement. At the same time, the ball 15 rubs against the inner surface of the clamping groove 8 during the rotation of the movable ring 14, thereby rotating, reducing the rotational friction of the movable ring 14, improving the effect of eliminating the impact force, and further improving the protection effect of the protective cover 5 on the float 7.
