Technical Field

[0001] This utility model relates to the field of land-based barrel aquaculture technology, and in particular to a land-based barrel escape prevention net and a land-based barrel. Background Technology

[0002] Land-based tank aquaculture is an emerging aquaculture method. Compared with traditional pond aquaculture, land-based tank aquaculture has advantages such as small footprint, high-density farming, and easy management. At the same time, the farming environment can be monitored, making the use of land resources more flexible.

[0003] The applicant knows that the land-based tank consists of a tank body and a waterproof cloth. A tank body is formed by steel plates at a selected location, and a waterproof cloth is laid inside the tank to form the land-based tank. However, during daily aquaculture, due to the special structure of the land-based tank, fish may try to escape the aquaculture area due to factors such as water flow, their own habits, or external disturbances. The escape area of ​​the fish is mainly concentrated near the inner edge of the tank body.

[0004] Therefore, there is an urgent need for a land-based bucket-type escape-proof net that can effectively prevent fish from escaping. Utility Model Content

[0005] The purpose of this utility model is to provide a land-based bucket escape-proof net and a land-based bucket to solve the problems existing in the prior art. By using a ring-shaped net to form a ring-shaped protective area at the edge of the top opening of the land-based bucket, it can effectively prevent fish from escaping.

[0006] To achieve the above objectives, this utility model provides the following solution: This utility model provides a land-based bucket escape-proof net, including a flexible annular net body. The top of the annular net body forms a constriction structure through an annular elastic rope. The diameter of the constriction structure is smaller than the inner diameter of the land-based bucket. The inner diameter of the bottom end of the annular net body is not smaller than the outer diameter of the land-based bucket. The bottom end of the annular net body is fitted onto the outer peripheral wall of the land-based bucket. The annular net body between the constriction structure and the top edge of the land-based bucket intercepts farmed fish.

[0007] Preferably, the annular mesh is fixedly mounted on the outer peripheral wall of the land-based bucket by fasteners.

[0008] Preferably, the fixing member is a ring-shaped clamp.

[0009] Preferably, the annular clamp is an elastic rope.

[0010] Preferably, the annular clamp is provided corresponding to the annular recess on the land-based barrel.

[0011] Preferably, the material of the ring net is the same as that of the fishing net.

[0012] Preferably, the ring mesh includes a first mesh wire and a second mesh wire, and a plurality of first mesh wires and a plurality of second mesh wires are obliquely woven together to form the ring mesh, wherein the number of first mesh wires is greater than the number of second mesh wires.

[0013] Preferably, the top of the annular net is provided with an annular cavity, and the annular elastic rope is disposed inside the annular cavity.

[0014] This utility model also provides a land-based barrel that uses the above-mentioned land-based barrel anti-escape net, wherein the ring-shaped net is fitted on the barrel body of the land-based barrel, and the constriction structure is located at the top opening of the barrel body.

[0015] Preferably, a flexible pad is provided along the top edge of the barrel.

[0016] The present invention achieves the following main technical effects compared to the prior art: After the entire ring net is placed over the land base barrel, due to the constricted structure at the top of the ring net, a ring-shaped protective area will eventually be formed at the edge of the top opening of the land base barrel, blocking the main escape area of ​​the fish and improving the fish's escape prevention effect. Moreover, the overall structure is simple and has the advantage of low cost.

[0017] The other solutions of this utility model achieve the following technical effects compared to the prior art: Fixing the ring-shaped net to the outer wall of the land-based container can prevent the ring-shaped net at the top opening of the land-based container from collapsing during use, thus reducing the anti-escape effect.

[0018] By using ring-shaped clamps to match the ring-shaped recesses on the land-based bucket, the firmness and stability of the ring net can be improved.

[0019] The first and second wires that cross within the ring mesh have better stress distribution performance, which can improve durability. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The purpose of this invention is to provide a land-based bucket escape-proof net and a land-based bucket to solve the problems existing in the prior art. By using a ring-shaped net to form a ring-shaped protective area at the edge of the top opening of the land-based bucket, it can effectively prevent fish from escaping.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please refer to the following: Figures 1-3 As shown, a land-based bucket escape-proof net is provided, including a flexible annular net body 1. The annular net body 1 can be formed by a single piece of netting, with both ends bound together. The mesh size of the annular net body 1 can be selected according to the fish being raised in the land-based bucket 3, and should be able to prevent fish from escaping through the mesh. The top of the annular net body 1 forms a constriction structure 2 through an annular elastic rope. The diameter of the constriction structure 2 is smaller than the inner diameter of the land-based bucket 3, and the inner diameter of the bottom end of the annular net body 1 is not smaller than the outer diameter of the land-based bucket 3. The bottom end of the annular net body 1 is fitted onto the outer peripheral wall of the land-based bucket 3. The constriction structure 2... The annular net 1 between the top edge of the land base tank 3 and the constricted structure 2 forms an annular protective area 4, which is used to protect the edge of the top opening of the land base tank 3, i.e., the main escape area for fish. This can improve the escape prevention effect of fish and will not have a negative impact on the ecological environment inside the land base tank 3. At the same time, the annular protective area 4 can also block external debris (branches, garbage, etc.) to prevent debris from entering the land base tank 3 from the annular protective area 4 and polluting the water in the land base tank 3.

[0026] To prevent the annular net 1 at the top opening of the land base 3 from collapsing and reducing its escape prevention effect, the annular net 1 is fixedly installed on the outer perimeter wall of the land base 3 using fasteners. At the same time, when installing the annular net 1, the bottom end of the annular net 1 should be pulled down as much as possible. With the help of the fasteners, the annular net 1 at the top opening of the land base 3 should be kept taut to improve the escape prevention effect.

[0027] In one embodiment, the fixing member is an annular clamp 5, which is used to fasten the annular net body 1 to the land base bucket 3.

[0028] The ring clamp 5 can be an elastic rope. In actual clamping, the clamping force can be increased by tightening both ends of the elastic rope and binding the two ends together, thereby improving the firmness and stability of the connection between the ring net body 1 and the land base barrel 3.

[0029] The ring clamp 5 can also be made of ordinary rope. Although the fixing effect is worse than that of elastic rope, it can still tighten the ring net 1 onto the land base barrel 3.

[0030] Since the outer wall of the steel plate used in some of the land base barrels 3 has multiple annular recesses 6 from top to bottom, and the whole structure is corrugated, the annular clamps 5 can be set to correspond to the annular recesses 6 on the land base barrel 3. The annular recesses 6 can be used to further improve the firmness and stability of the connection between the annular net body 1 and the land base barrel 3.

[0031] Alternatively, during the production stage, an annular recess 6 can be provided on the outer peripheral wall of the land base barrel 3 to accommodate the clamp of the annular clamp 5.

[0032] In one embodiment, the fastener can also be a bolt and a baffle. The nut of the bolt can be welded to the land base 3, and a hole can be made in the land base 3 at the position corresponding to the nut for the bolt to pass through (since a waterproof cloth is installed inside the land base 3, the operation of making the hole will not cause water loss). The bolt thread passes through the baffle and the mesh of the annular net 1 in sequence and then connects with the nut. At this time, the bolt achieves the fixation of the annular net 1. At the same time, the size of the baffle should be larger than the size of the mesh to prevent the annular net 1 from coming off from the large end of the bolt.

[0033] In one embodiment, the material of the ring net 1 is the same as that of the fishing net. The material combines high-strength fibers and anti-corrosion chemicals. The high-strength fibers can greatly improve the tensile strength of the escape-proof net, making it less prone to damage when facing large impacts and external tensions. The addition of anti-corrosion chemicals effectively extends the service life of the escape-proof net in harsh environments and reduces the cost increase caused by frequent replacement of the escape-proof net.

[0034] The ring net 1 includes a first net line 7 and a second net line 8. Multiple first net lines 7 are arranged in parallel, and multiple second net lines 8 are arranged in parallel. Multiple first net lines 7 and multiple second net lines 8 are obliquely woven to form the ring net 1. The number of first net lines 7 is greater than the number of second net lines 8. This design allows the ring net 1 to have better force distribution performance.

[0035] The specific design of the constriction structure 2 is as follows: the top of the ring net body 1 is provided with a ring cavity, which is formed by folding the edge of the ring net body 1 and binding it to the unfolded part. A ring elastic rope is provided inside the ring cavity.

[0036] This utility model also provides a land-based barrel 3 that uses the above-mentioned land-based barrel escape-proof net. The barrel body of the land-based barrel 3 is fitted with an annular net body 1, and the constriction structure 2 is located at the top opening of the barrel body to form an annular protective area 4 to prevent fish from escaping from there.

[0037] Since the barrel is generally formed by steel plates, a flexible pad is provided at the top edge of the barrel. The bottom of the flexible pad is provided with an insertion interface, which is inserted and connected to the top edge of the barrel. The flexible pad can not only prevent the top edge of the barrel from damaging the waterproof cloth, but also prevent damage to the ring net 1.

[0038] Any adaptive changes made according to actual needs are within the protection scope of this utility model.

[0039] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0040] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
