Description

Bottom trawl

The present invention relates to fishing nets, and more particularly to an undirected bottom trawl.

Referring to Figure 1, today's bottom-to-fish fishing uses a vessel tow the bottom trawl to capture the catch on the seabed by bottom trawling. The existing bottom trawl is mostly tapered, has a pointed end, and has an opening at the other end, and the opening is upward when dragging. After the fishing is completed, the vessel will take the net out of the sea and take a catch through the opening into the bottom trawl. The disadvantage is that when the catch is small, the fish caught in the opening can not suck the catch at the end of the trawl, so the bottom trawl needs to be retracted to a higher height in order to absorb the catch, and the net at the opening needs to be arranged. Conducive to the insertion of the suction tube, it is quite inconvenient. Furthermore, the catch is towed at the pointed end of the bottom trawl and is easily broken by squeezing.

In view of the above, the inventors of the present invention have made great efforts to solve the above problems in view of the above-mentioned prior art, and have made great efforts to solve the above problems, which has become the object of improvement of the present inventors.

The main object of the present invention is to provide an undirected bottom trawl.

In order to achieve the above object, the present invention provides a bottom trawl comprising a mesh bag and a plurality of fixing cables. The mesh bag comprises a plurality of ring networks connected in series and connected to each other, and each ring network comprises a side mesh connected by a plurality of ring columns. Each of the fixing cables is respectively disposed between the adjacent two side meshes to form a quick release restraining structure to bind the two side meshes.

Preferably, one end of the mesh bag is a closed end, and the other end is an open end of the opening, and the open end can be connected with at least one cable. Each side mesh has a trapezoidal shape, and the trapezoidal short sides of each side mesh are arranged toward the end. The bottom end is provided with a bottom mesh which is substantially regular in shape and which is connected to the side mesh at the end to close the end. The rings are of different sizes and are arranged in descending order from the open end to the end.

Preferably, the quick release binding structure bends the fixing cable into a plurality of collars arranged in a series, and the adjacent two collars respectively pass through the adjacent side meshes and then are fixed to each other. Each ring first Pass through one of the adjacent rings and then pass through the other adjacent ring. Therefore, the quick release binding structure can interlock the release collar and quickly separate the two side meshes.

The bottom trawl of the present invention of the present invention is capable of inserting a fish suction tube therein by unfastening the fixing cable in any direction.

Referring to Figures 2 through 3, a preferred embodiment of the present invention provides a bottom trawl comprising a mesh bag 100 and a plurality of fixing cables 200.

The mesh bag 100 is in the form of a strip, which comprises a plurality of ring nets 110 connected in series, and the ring nets 110 are connected to each other. One end of the mesh bag 100 is a closed end 101, and the other end is an open end 102 having an opening shape. In this embodiment, the ring networks 110 are all different in size, and each ring network 110 includes a plurality of side meshes 111 connected by a plurality of rings. Each of the side nets 111 has a trapezoidal shape, and the trapezoidal short sides are disposed toward the end of the net bag 100, and the ring nets 110 are arranged in descending order from the open end 102 of the net bag 100 toward the end 101 of the net bag 100. The bottom trawl of the present invention is tapered. The end 101 of the mesh bag 100 is provided with a bottom mesh 120 for closing the ring net 110 at the end 101 such that the end 101 of the bottom trawl is closed. In this embodiment, the bottom mesh 120 is interposed between the side meshes 111 at the end 101 and connected to the side nets 111 at the end 101, respectively, and the bottom mesh 120 is a nearly circular regular polygon. The end of the bottom trawl is a nearly circular positive multilateral shape. In the embodiment, the end 101 of the net bag 100 has a regular hexagon shape, and the bottom mesh piece 120 of the end 101 of the net bag 100 is a regular hexagon and is respectively connected to each side mesh 110 adjacent thereto, but the present invention does not This is limited. At least one cable 103 is attached to the open end 102 of the mesh bag 100 for towing by the vessel.

Referring to FIG. 4, each of the fixing cables 200 is disposed between the adjacent two side mesh sheets 111 to form a quick release restraining structure 210, and the two side mesh sheets 111 are fixedly connected by the quick release binding structure 210.

Referring to FIG. 4 and FIG. 5 , in this embodiment, one of the fixing cables 200 and the two side mesh 111 fixed and fixed thereto is taken as an example. One end of the fixing cable is a fixed end 201, and the other end of the fixing cable is a releasing end 202. The fixed end 102 is fixedly bound to one side of the mesh 111, and the quick release binding structure 210 includes a plurality of collars 211 formed between the fixed end 201 and the releasing end 202 of the fixing cable 200 and arranged in a string, each ring 211 is formed by bending the fixing cable 200, respectively. The adjacent collars 211 are respectively connected to different side nets 111, and each of the collars 211 is connected to another ring 211 adjacent to one side thereof and sleeved with The other set of rings 211 adjacent to one side is illustrated by the following example in which three sets of rings 211 are taken as an example. From the fixed end 201, the adjacent two sets of rings 211 pass through the side nets 111 and are then fixed to each other. Referring to FIG. 6, the collar 211 preferably first passes through one of the adjacent collars 211 that is closer to the fixed end 201, and then passes through the collar 211 of the other adjacent side, thereby causing the collars 211 to be inserted. Secure each other. Repeatingly fixing all of the collars 211 and fixing the release ends 202 to prevent the loops 211 from coming loose, that is, completing the quick release restraint structure 210 and thereby fixing the two side meshes 111 to each other. Moreover, by simply releasing the release end 202 and pulling the release end 202, the collars 211 can be interlocked and released, whereby the adjacent two-sided mesh 111 can be quickly separated.

Referring to Figure 7, the bottom trawl of the present invention has the advantages described below over the prior art. By fixing the side mesh 111 by the fixing cable 200, any one of the fixing cables 200 can be released to separate the side nets 111 on both sides of the fixing cable 200, thereby being able to insert the suction pipe through different places on the bottom tracing net. 10 to pick up the catch 20 in the net bag, so there is no need to pull the bottom trawl completely out of the water. The present invention provides an undirected bottom trawl that can insert the fish suction tube 10 therein in any direction as compared to conventional techniques that require the opening to be upward to facilitate insertion of the fish suction tube 10. Moreover, the end 101 is substantially a nearly circular regular polygon, so that the space formed therein is larger than the space formed in the tapered end of the conventional bottom trawl, so the bottom trawl of the present invention is more The bottom trawl can hold more catches, and the catch 20 will not be squeezed at the end and the death will be broken.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the patent scope of the present invention. All other equivalent variations of the patent spirit of the present invention are intended to be within the scope of the invention.
