Description

Round-up fishing net structure

The present invention relates to a fishing net for fishing, and in particular to a fishing net structure for rounding up.

Traditional fishing nets are mainly composed of meshes woven into multiple meshes, and the size of the net is smaller than the size of the fish to be caught. Therefore, when the fishing boat pulls the fishing net to catch fish, it is not easy to escape from the net by catching the fish into the fishing net. The fishing net and the caught fish are returned to the boat, and then the caught fish are searched for the fish to be caught.

However, the above fishing nets have the following disadvantages. Because of the large size and heavy weight of the fishing nets, if the plurality of nets cannot be folded or brought together during the process of closing the nets, it will cause problems such as unfolding of the nets and excessive storage space. It has been criticized for a long time because it is unfavorable for the subsequent fishing catch or the tidying of fishing nets.

In view of this, the inventor of the present invention focused on the above-mentioned prior art, and made great efforts to solve the above-mentioned problems, which became the goal of the inventor's development.

The present invention provides a fishing net structure that utilizes the fishing net body to be retracted, the plural first diamond-shaped meshes and the plural second diamond-shaped meshes will be folded and merged by themselves to achieve the effect of reducing the volume of the fishing net and improving the smoothness of the net. .

In the embodiment of the present invention, the present invention provides a fishing net structure, including: a fishing net body, including a woven net, and an upper rope and a lower rope that are sequentially arranged on the woven net, lower, left, and right sides Rope, a left arch hand net and a right hand arch net, the woven net has a middle section, a dividing rope arranged between the upper rope and the lower rope, and woven between the upper rope and the dividing rope And a plurality of mesh areas parallel to each other horizontally and a plurality of lower mesh areas woven between the lower rope and the boundary rope and parallel to each other horizontally; wherein each of the mesh areas has a plurality of first diamond meshes, each The lower mesh area has a plurality of second diamond-shaped meshes, the plurality of first diamond-shaped meshes and the plurality of second diamond-shaped meshes are arranged inversely with respect to each other based on the dividing rope, and the size of the first diamond-shaped mesh of the plurality of meshes is determined by the The left arching net and the right arching net gradually decrease toward the middle segment, and the size of the second diamond mesh in the plural lower net area gradually decreases from the left arching net and the right arching net toward the middle segment. There is a first separation rope between two adjacent mesh areas, and the side of the first diamond mesh on one side of the first separation rope is formed by the sides of the two adjacent first diamond meshes on the other side , Each of the first separating ropes is an inclined line from the separating rope to the upper enclosing rope gradually approaching the middle mesh section, and a second separating rope is located between the two adjacent lower mesh areas. The side of the second diamond mesh on one side of the second separation rope is formed by the sides of the two adjacent second diamond meshes on the other side, and each second separation rope starts from the dividing rope to the lower encircling rope Gradually approach a sloping line of the middle segment.

Based on the above, the plural first diamond-shaped meshes and the plural second diamond-shaped meshes are arranged opposite to each other based on the dividing rope. Therefore, when the fishing net body is pulled, the plural first diamond-shaped meshes and the plural second diamond-shaped meshes will move closer to the middle of the woven net. It further strengthens the smoothness of net reeling of the fishing net structure.

Based on the above, each first separating rope is the inclined line from the boundary rope to the upper fence gradually approaching the middle segment, and each second separating rope is the inclination line from the boundary rope to the lower fence gradually approaching the middle segment. The slash is to guide the multiple net mesh area and the plural lower mesh area to overlap along the pulling direction to the middle net section position, so that the rounding fishing net structure is more smooth when the net is closed.

The fishing net body 1 includes a woven net 2 and the upper, lower, left, and right sides of the woven net 2 are surrounded in sequence. On the right side are an upper rope 3, a lower rope 4, a left arch hand net 5, and a right arch hand net 6. The woven net 2 has a middle section 7 in the middle, and the woven net 2 further has the upper and lower ropes 3 and A dividing rope 21 in the middle of the rope 4, a plurality of mesh areas 22 woven between the upper rope 3 and the dividing rope 21 and horizontally parallel to each other, and plural woven between the lower rope 4 and the dividing rope 21 and horizontally parallel to each other Under the mesh area 23.

Among them, each net mesh area 22 has a plurality of first diamond meshes 221, each lower mesh area 23 has a plurality of second diamond meshes 231, the plurality of first diamond meshes 221 and the plurality of second diamond meshes 231 The dividing ropes 21 are arranged in opposite directions to each other based on the reference, and the size of the first diamond mesh 221 of the plural net mesh area 22 gradually decreases from the left hand net 5 and the right hand net 6 toward the middle net section 7. The size of the two rhombus meshes 231 gradually decreases from the left hand mesh 5 and the right hand mesh 6 toward the middle mesh section 7.

The detailed description is as follows. As shown in FIG. 3, the weaving direction of the plural first diamond meshes 221 is opposite to the weaving direction of the plural second diamond meshes 231, and the number of segments of the plural net mesh areas 22 and the plural lower mesh areas 23 is equal to The positions are the same, so the plurality of first diamond meshes 221 and the plurality of second diamond meshes 231 are arranged in opposite directions and symmetrically with each other based on the dividing rope 21.

In addition, in this embodiment, the size of the first diamond mesh 221 of the adjacent two mesh areas 22 and the second diamond mesh 231 of the adjacent two lower mesh areas 23 are changed as follows. A first separation rope 24. The side of the first diamond mesh 221 located on one side of the first separation rope 24 is formed by the sides of two adjacent first diamond meshes 221 on the other side, and the adjacent two lower mesh areas 23 There is a second separation rope 25 therebetween, and the side of the second diamond mesh 231 on one side of the second separation rope 25 is formed by the side of two adjacent second diamond meshes 231 on the other side.

Furthermore, each first separating rope 24 is an inclined line starting from the dividing rope 21 to the upper hoisting rope 3 gradually approaching the middle mesh section 7, and each second separating rope 25 is gradually starting from the dividing rope 21 to the lower hoisting rope 4 An inclined line close to the middle segment 7.

In addition, the mesh size of the middle segment 7 is smaller than the size of the first diamond mesh 221 and the size of each second diamond mesh 231. Because the fish school 200 is mainly concentrated in the middle segment 7 during rounding up, the mesh size of the middle segment 7 is small It can prevent the school of fish 200 from slipping away from the mesh.

As shown in FIG. 1, the upper rope 3 is a rope body that can float on the sea surface. In this embodiment, a plastic rope is used as an example for description, but it is not limited thereto. Wherein, the upper rope 3 is connected to the upper side of the fishing net body 1 to facilitate the upper rope 3 to float on the sea surface.

As shown in Fig. 1, the lower rope 4 is a rope body that can be sunk into the sea. In this embodiment, a nylon rope is used as an example for description, but it is not limited thereto. Among them, the lower rope 4 is connected to the lower side of the fishing net body 1 to It is beneficial for the lower rope 4 to sink into the sea, and the fishing net body 1 can be relatively pulled apart relative to the upper rope 3, which is beneficial to the progress of the fishing group. Among them, the upper rope 3 and the lower rope 4 can adopt low-extension rope bodies, so as to prevent the fishing net body 1 from being deformed.

Furthermore, each first separating rope 24 is an inclined line starting from the dividing rope 21 to the upper hoisting rope 3 gradually approaching the middle mesh section 7, and each second separating rope 25 is starting from the dividing rope 21 to gradually approaching the lower hoisting rope 4 The inclined line of the middle segment 7 to guide the plural net mesh area 22 and plural lower mesh area 23 along the retracting direction (from the left hand net 5 and the right hand net 6 to the middle net section 7) Section 7 is folded in position to make the rounding fishing net structure 10 smoother.

Also, when pulling the fishing net body 1, the school of fish 200 will gather in the middle of the woven net 2 first, and will not slip away from the mesh until there is insufficient space in the middle of the woven net 2, so the size of the first diamond mesh 221 of the plural mesh area 22 From the left arch hand net 5 and the right arch hand net 6 to the middle segment 7 gradually decrease, the size of the second diamond mesh 231 in the mesh area 23 under the plural number gradually decreases from the left arch hand net 5 and the right arch hand net 6 towards the middle segment 7 , So that the meshes of the woven net 2 are large on both sides and small in the middle. Compared with the fishing nets that are all small meshes, the rounding fishing net structure 10 of the present invention has the advantages of low cost, light weight and small size.

Please refer to Figure 4, which is another embodiment of the fishing net structure 10 of the present invention. The embodiment of Figure 4 is substantially the same as the embodiment of Figures 1 to 3, and the embodiment of Figure 4 is different from the embodiment of Figures 1 to 3 The point is that the structure of the intermediate segment 7 is different.
