Abstract
Description
Technical Field
[0001] The utility model specifically relates to a fishing net structure for salvage. Background Art
[0002] In the field of fishery fishing technology, traditional fishing net designs often focus on improving fishing efficiency and selective fishing ability while reducing adverse impacts on the marine ecosystem. However, many existing fishing net structures have some limitations in practical applications. Especially when ensuring efficient fishing, it is difficult to effectively avoid bycatch and protect juvenile fish and non-target species. In the traditional aquaculture industry, especially for fish, fish are cultured in ponds. After a period of breeding, the fish in the ponds are caught. However, there are many drawbacks in the existing traditional fishing process. For example, when using the traditional dragnet fishing operation, the whole fishing process takes a long time, the work efficiency is low, and it is easy to miss the net. Since the fish are forced to be driven by the dragnet, the fish are prone to struggle, resulting in fish injuries or the fishing net being torn. Another example is when using the traditional method of pumping water first and then catching fish. The process of catching fish is more time-consuming and laborious, and it is easy to cause damage or even death of aquatic products. No matter which method is used, it is easy to cause fish losses, and the difficult operation leads to an increase in labor and time costs.
[0003] The present utility model is precisely produced based on the above deficiencies. Summary of the Utility Model
[0004] The purpose of the present utility model is to overcome the deficiencies of the prior art and provide a fishing net structure for salvage with high efficiency and low loss.
[0005] The present utility model is achieved by the following technical solutions:
[0006] A fishing net structure for salvage includes a fishing net body, which is composed of a plurality of fishing net monomers spliced together. A fishing hole is provided in the middle of each fishing net monomer, which can allow aquatic products to pass through from bottom to top when it sinks. A cover net or a tubular net is detachably connected to the fishing net monomer at the position corresponding to the fishing hole. When the fishing net monomer is connected to the cover net, the edge of the cover net is connected to the edge of the fishing hole to seal the fishing hole. When the fishing net monomer is connected to the tubular net, the lower edge of the tubular net is connected to the edge of the fishing hole, so that the inner side of the tubular net and the fishing hole form a fishing channel for aquatic products to swim from the lower side of the fishing net monomer to the upper side of the fishing net monomer.
[0007] The fishing net structure for salvage as described above is composed of a plurality of fishing net monomers spliced together, and a cover net is connected to some of the fishing net monomers, while a tubular net is connected to the rest of the fishing net monomers.
[0008] The fishing net structure for salvage as described above, the adjacent fishing net monomers are connected by a zipper.
[0009] For the fishing net structure described above, the edge of the cover net is connected to the edge of the fishing hole by a zipper.
[0010] For the fishing net structure described above, the lower edge of the cylindrical net is connected to the fishing hole by a zipper.
[0011] For the fishing net structure described above, the diameter of the cylindrical net gradually decreases from bottom to top.
[0012] For the fishing net structure described above, an airbag is connected to the top of the cylindrical net, which is used to pull up the top of the cylindrical net when the fishing net unit sinks.
[0013] For the fishing net structure described above, a pulling rope is also connected to the top of the cylindrical net.
[0014] For the fishing net structure described above, a buoy is connected to the free end of the pulling rope.
[0015] For the fishing net structure described above, a partition net is detachably connected to the upper surface of the fishing net body. The lower edge of the partition net is connected to the upper surface of the fishing net body, and the partition net has a structure that is larger at the top and smaller at the bottom.
[0016] Compared with the prior art, the present utility model has the following advantages:
[0017] When using the fishing net structure of the present utility model, it is only necessary to slowly sink the fishing net body first, and then pull up the fishing net body to catch aquatic products. During the whole process, the aquatic products swim into the capture net by themselves, and the degree of fright or injury to the aquatic products is greatly reduced. Therefore, the survival rate of the aquatic products is high, the fishing gear is less likely to be damaged, the service life of the fishing gear is increased, and at the same time, the operation is very convenient, without a large number of steps of operating in the water, saving time and effort, and improving the operation efficiency.

[0029] Embodiment 1:
[0030] This embodiment provides a fishing net structure, including a fishing net body A. When in use, the fishing net body A is laid on the breeding pond. In order to adapt to breeding ponds of different sizes, as Figure 1 shown, the fishing net body A is spliced by a number of fishing net monomers 1. The specific splicing method is through a zipper. As Figure 2 shown, that is, the shape of the fishing net body A is designed as a rectangle or a polygon. A zipper cloth tape, that is, a single chain of the zipper, is arranged on the edge of the fishing net body A, and only the zipper pull head B is reserved on a part of the edge of the fishing net body A. For example, the fishing net body A is a rectangular structure, and its upper side and left side are connected with the zipper cloth tape and the zipper pull head B is reserved, and its lower side and right side are connected with the matching zipper cloth tape; or adjacent fishing net bodies A can also be tied tightly together by ropes, or other methods can connect two adjacent fishing net bodies A to form a fishing net body A with a larger area. As Figures 2 to 5As described above, a fishing hole 10 through which aquatic products can pass from bottom to top when the fishing net unit 1 sinks is provided in the middle of the fishing net unit 1. A cover net 2 or a tubular net 3 is detachably connected to the fishing net unit 1 at a position corresponding to the fishing hole 10. The shape of the cover net 2 matches that of the fishing hole 10. The tubular net 3 penetrates up and down, and the shape of the lower opening of the tubular net 3 matches that of the fishing hole 10, so that the cover net 2 and the tubular net 3 can be selectively connected to the fishing net unit 1. When the fishing net unit 1 is connected to the cover net 2, the edge of the cover net 2 is connected to the edge of the fishing hole 10 to seal the fishing hole 10. When the fishing net unit 1 is connected to the tubular net 3, the lower edge of the tubular net 3 is connected to the edge of the fishing hole 10, so that a fishing channel 100 through which aquatic products can swim from the lower side of the fishing net unit 1 to the upper side of the fishing net unit 1 is formed between the inner side of the tubular net 3 and the fishing hole 10. In this way, a single fishing net unit 1 can be used alone, or multiple fishing net units 1 can be combined to form a fishing net body A for use. When used in combination to form the fishing net body A: when all the fishing net units 1 of a fishing net body A are connected with cover nets 2, the fishing net body A can be used as an ordinary fishing net; when some or all of the fishing net units 1 of a fishing net body A are connected with tubular nets 3, during use, first cover the fishing net body A on the breeding pond, and the fishing net body A slowly sinks. When the aquatic products instinctively swim upstream, the aquatic products can only swim to the upper side of the fishing net body A through the fishing channel 100. Then, it is generally difficult for the aquatic products to swim from the upper side of the fishing net body A to the upper end of the tubular net 3 and then swim downstream through the fishing channel 100 to the lower side of the fishing net body A, so that most of the aquatic products stay in the water area on the upper side of the fishing net body A. When the fishing net body A sinks to the bottom of the breeding pond or sinks to other appropriate positions, the fishing net body A can be pulled up to catch the aquatic products. During the whole process, the aquatic products swim into the catching net by themselves, and the degree of fright or injury to the aquatic products during the process is greatly reduced. Therefore, the survival rate of the aquatic products is high, the fishing gear is less likely to be damaged, the service life of the fishing gear is prolonged, and at the same time, the operation is very convenient, without a large number of steps of operating in the water, saving time and effort, and improving the operation efficiency. In order to improve the efficiency, in actual operation, before the fishing net body A sinks, each fishing net unit 1 can be connected with a tubular net 3. After the fishing net body A sinks to the bottom of the breeding pond, the tubular net 3 can be disassembled and replaced with a cover net 2, so as to prevent the aquatic products from swimming to the lower side of the fishing net body A and improve the fishing efficiency. In order to adapt to larger breeding ponds, as Figure 9 shown, in actual operation, a larger fishing net structure is often formed by splicing and combining multiple fishing net bodies A.
[0031] Preferably, as Figure 3 shown, the edge of the cover net 2 and the edge of the fishing hole 10 are connected by a zipper. That is, a zipper cloth tape is provided on the edge of the cover net 2, that is, a single chain of the zipper. A corresponding zipper cloth tape is provided on the edge of the fishing hole 10, and only one of them retains the zipper pull head B.
[0032] Preferably, as Figure 4 shown, the lower edge of the cylindrical net 3 and the fishing hole 10 are connected by a zipper. That is, a zipper tape is provided at the lower edge of the cylindrical net 3, that is, a single chain of the zipper. A corresponding zipper tape is provided at the edge of the fishing hole 10, and only the zipper pull B needs to be retained on one of them.
[0033] In this embodiment, zipper tapes are provided at the edges of the cover net 2 and the lower edge of the cylindrical net 3, and a corresponding zipper tape is provided at the edge of the fishing hole 10 and the zipper pull B is retained to facilitate fitting and installation.
[0034] Preferably, as Figure 4 shown, in order to reduce the probability of aquatic products swimming downstream from the top of the cylindrical net 3, the diameter of the cylindrical net 3 gradually decreases from bottom to top.
[0035] Embodiment 2:
[0036] A fishing net structure, which is different from Embodiment 1 in that:
[0037] 1. As Figure 6 shown, an airbag 31 for pulling up the top of the cylindrical net 3 when the fishing net unit 1 sinks is connected to the top of the cylindrical net 3;
[0038] 2. As Figure 6 shown, a pulling rope 32 is also connected to the top of the cylindrical net 3;
[0039] 3. As Figure 6 shown, a buoy 33 is connected to the free end of the pulling rope 32.
[0040] As Figure 5 and Figure 7 shown, during use, when the fishing net body A sinks, the airbag 31 can pull up the top of the cylindrical net 3, and the airbag 31 itself has a small volume and small buoyancy, which can pull the cylindrical net 3 into an erected state without affecting the sinking of the fishing net body A. This facilitates opening the cylindrical net 3 for aquatic products to pass through. The pulling rope 32 is convenient for preventing the cylindrical net 3 from naturally closing when collecting the net. In order to facilitate identifying the position of the cylindrical net 3, a buoy 33 is connected to the free end of the pulling rope 32.
[0041] Embodiment 3:
[0042] A fishing net structure, which is different from Embodiment 1 in that: As Figure 8As shown in the figure, a partition net C is detachably connected to the upper surface of the fishing net body A. The lower edge of the partition net C is connected to the upper surface of the fishing net body A. Moreover, the partition net C has a structure that is larger at the top and smaller at the bottom. The lower edge of the partition net C and the upper surface of the fishing net body A can be connected by a binding rope or a zipper. That is, a zipper cloth tape is provided at the lower edge of the partition net C, which is a single chain of the zipper. A corresponding zipper cloth tape is provided on the upper surface of the fishing net body A, and only one of them needs to retain the zipper pull head. In order to separate aquatic products of different sizes, through holes C1 with different aperture sizes can be provided on the partition net C, so that aquatic products of different sizes can be left on both sides of the partition net C.
[0043] The above are only embodiments of the present invention. Common knowledge such as specific structures and characteristics known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to explain the content of the claims.
